Wireless PCI Card
Planning Your Wireless Network
Network Topology
A wireless LAN is exactly like a regular LAN, except that each computer in the
LAN uses an Instant Wireless™ Wireless PCI Card to connect to the network
using no wires. Computers in a wireless LAN must be configured to share the
same radio channel.
The Instant Wireless™ Wireless PCI Card provides LAN access for wireless
workstations. An integrated wireless and wired LAN is called an Infrastructure
configuration. A group of Wireless PCI Card users and an Access Point compose a Basic Service Set (BSS). Each PC equipped with an Wireless PCI Card
in a BSS can talk to any computer in a wired LAN infrastructure via the Access
Point.
Package Contents
• One Instant WirelessTM Wireless PCI Card
• One Setup CD-ROM (Manual on CD)
• Quick Installation Guide and Registration Card (not shown)
System Requirements
• One Free PCI Slot
• Windows 95, 98, Millennium, NT or 2000
• 600 Kbytes of free disk space for utility and driver installation
An infrastructure configuration extends the accessibility of an Wireless PCI
Card PC to a wired LAN, and doubles the effective wireless transmission range
for two Wireless PCI Card PCs. Since the Access Point is able to forward data
within its BSS, the effective transmission range in an infrastructure LAN is
doubled.
The use of a unique ID in a Basic Service Set is essential.
The Wireless LAN Infrastructure configuration is appropriate for enterprisescale wireless access to a central database, or as a wireless application for
mobile users.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. More
than one BSS can be configured as an Extended Service Set (ESS). This continuous network allows users to roam freely within an ESS. All Wireless PCI
Card PCs within one Extende Service Set must be configured with the same
SSID.
Selecting a feasible radio channel and optimum Access Point position is recommended. Proper Access Point positioning combined with a clear radio signal will greatly enhance performance.

Wireless PCI Card
2. The first tab across the top of the screen, labeled Install, should now be highlighted. Click on the Install button. The following screen should appear,
indicating that Windows is preparing the installation.
Before You Start
Your new Instant Wireless™ Wireless PCI Card comes with an automated software installation procedure for Windows 95, 98, Millennium, and 2000.
Windows NT users should refer to the next section. This new procedure automatically installs the drivers and Configuration Utility before you install your
hardware, so there’s no searching for the location of drivers. Again, this step is
taken before installing your hardware.
Running the Auto Driver Installation
1. Before installing your adapter, insert the Setup CD into your CD-ROM drive.
Unless you have deactivated the auto-run feature of Windows, the following
screen should appear automatically.
If, for whatever reason, you need to abort or terminate the installation, press
the Cancel button at any time during the installation. Otherwise the installation will continue automatically.
Note: If you stop the installation before it has finished, you will have to
run the installation completely again before installing your hardware.
3. This screen will appear next, indicating that Windows is ready to continue
the installation. Click the Next button.
If this screen does not appear automatically, you can access the installation
by pressing the Start button and choosing Run. In the drop down box provided, type D:\setup.exe (where D: is the letter of your CD-ROM drive).
Alternately, double-click My Computer, and then double-click the CDROM drive where the Setup CD is located. Then double-click the Setup.exe
icon that appears.
Instant WirelessTM Series
4. The next screen that appears will be the Warranty Policy. Read the entire
policy by pressing the Page Down button on your keyboard. Click on the
Yes button if you agree, or No if you disagree. Clicking No will terminate
the installation. If you click Yes, the installation will continue.
Wireless PCI Card
6. When the following screen appears, choose either Infrastructure mode or
Ad-Hoc mode, depending on your needs. If you are unsure whether to
choose Infrastructure or Ad-Hoc, refer to the next section for more information. Once you have made your choice, click the Next button.
5. The following window will appear next. To install the Configuration Utility
in the default directory (recommended), click the Next button. If you prefer to install the Utility in another directory, click the Browse button, locate
the preferred directory then click the Next button.
Instant WirelessTM Series
Ad-Hoc versus Infrastructure Mode
Unlike wired networks, wireless networks have two different modes in which
they may be set up: Infrastructure and Ad-Hoc. Choosing between these two
modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.
If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral, such as a printer, with the wired network
computers, the wireless network should be set up in the Infrastructure mode.
The basis of Infrastructure mode centers around an access point, which serves
as the main point of communications in a wireless network. Access points
transmit data to PCs equipped with wireless network card, which can roam
within a certain
radial range of
the access point.
Multiple access
points can be
arranged to work
in succession to
extend the roaming range, and
can be set up to
communicate
with your Ethernet
hardware as well.
Wireless PCI Card
Infrastructure Mode
1. If you have chosen Infrastructure mode, the following screen will appear.
If you have chosen Ad-Hoc mode, skip to the next section.
You will be prompted to enter an SSID value in the box provided. The
SSID may be up to 32 characters in length and may include any character
on the keyboard. All SSID values on your wireless network must match. If
you are unsure, use the default value of “linksys”. Then, click the Next button. Note: All characters are case-sensitive.
2. The next screen to appear will be the Review Settings screen. Verify that
all the settings are correct and click the Next button to continue.
If the wireless network is relatively small and needs to share resources only
with the other computers on the wireless network, then the Ad-Hoc mode can
be used. Ad-Hoc mode allows computers equipped with wireless transmitters
and receivers to communicate directly with each other, eliminating the need for
an access point. The drawback of this mode is in the fact that, in Ad-Hoc mode,
wireless-equipped computers are not able to communicate with computers on
a wired network. And,
of course, communication between the wireless-equipped computers is limited by the distance and interference
directly between them.
Instant WirelessTM Series
3. The following screen will appear, indicating that all of the appropriate files
are being copied onto your drive. Click the Cancel button if you need to
stop the installation for any reason.
4. Once Windows has finished copying the necessary files, the following
screen will appear. In order for the drivers to be installed properly, you
must restart your computer. If you choose to do it now, select Yes, I want
to restart my computer now. If you do not want to do it now, choose No,
I will restart my computer later. Once you have made your choice, click
the Finish button to continue.
Wireless PCI Card
Ad-Hoc Mode
1. If you have chosen Ad-Hoc mode, the following screen will appear. If you
have chosen Infrastructure mode, refer to the previous section.

Configuration Utility
LINK INFO
The Configuration Utility is provided to allow you further customization of
the Wireless PCI Card and your wireless network.
The Link Info screen provides information about the current link between the
Wireless PCI Card and the wireless Access Point.
Using the Configuration Utility
Once the Configuration Utility has been installed, an icon will be placed in the
system tray (next to the clock) when the Wireless PCI Card is inserted.
This icon (which looks like a
small computer) serves two purposes. Double-clicking on the
icon will open the Configuration
Utility. The other function of the icon is to indicate the status of your wireless
connection. The icon does this by changing color. The different colors each
indicate a different quality of wireless connection. The chart below details
what the colors are and what each one means.
Note: In Ad-Hoc mode, the icon will always appear green. When in
this mode, the icon color does not apply to the Link Quality and Signal
Strength of the wireless connection.
You can also start the Configuration Utility by pressing the Start button and
selecting Wireless PCI Card. Then choose Configuration Utility. You will see
the Wireless LAN Configuration Utility screen. This utility is divided into four
parts: Link Info, Configuration, Site Survey, Encryption, Advanced, and
About. It is recommended that you change all configuration settings for your
Wireless PCI Card using this utility and not under the Network Properties section in your Control Panel.
Note: When in
Ad-Hoc mode,
Link Quality and
Signal Strength
indicators will
not be available.
The Current Channel field shows to what channel the Wireless PCI Card is set.
The Current Transmit Rate field shows the transfer rate in megabits per second.
The Throughput fields show the rate at which data is transferred and received in
Bytes per second.
The Link Quality field will display a bar indicating the percentage, between 0 and
100 percent, of the quality of the link. The higher the percentage, the better the
link.
The Signal Strength field will display a bar indicating the percentage, between 0
and 100 percent, of the strength of the signal. The higher the percentage, the
stronger the signal. (This is to be used as a guide only and not an indicator true
signal strength or quality.)

CONFIGURATION
The Configuration screen allows you to customize the settings for the Wireless
PCI Card and your wireless network. Once these are set, you can save these
configuration settings with the Profile function. Click Create to save your configuration settings and Activate to use these settings. To delete settings you
have saved, use the Remove button.
The Wireless Mode setting determines the architecture of your wireless network. Select Ad-Hoc or Infrastructure Mode depending on your network
type. The Ad-Hoc mode is used for a simple peer-to-peer network and allows
the sharing of local resources only between Wireless PCI Cards without needing a wireless Access Point. The Infrastructure mode allows a wireless network to be integrated into an existed, wired network through an Access Point.
Infrastructure networks permit roaming between Access Points while maintaining a connection to all network resources.
Wireless PCI Card
The Channel setting specifies the channel used in wireless communication and
should be set to the same channel as the other points in the wireless network.
This setting can only be adjusted in Ad-Hoc mode.
ENCRYPTION
The 64-bit or 128-bit WEP keys can be generated from a user-defined
passphrase or entered manually.
An acronym for Wired Equivalent Privacy, WEP is an encryption scheme used
to protect your wireless data communications. WEP uses a combination of 64bit or 128-bit keys to provide access control to your network and encryption
security for every data transmission. To decode a data transmission, each point
in a network must use an identical 64-bit or 128-bit key. Higher encryption
levels mean higher levels of security, but, due to the complexity of the encryption, they may mean decreased network performance.
An acronym for Service Set Identifier, SSID is the unique name shared among
all points in a wireless network. The SSID must be identical for all points in the
network. It is case sensitive and must not exceed 32 characters.
The Transfer Rate field shows the current transfer rate for the Wireless PCI
Card. To optimize
performance
and
range, the TX Rate
should be set to
Fully Automatic,
which will automatically adjust the
transfer speed for
best performance
and longest range.
Power Saving Mode,
or
PS
Mode,
enables or disables
the power saving
features of your
Wireless PCI Card.
32
Encryption (WEP) can be Disabled, or set to 64-bit or 128-bit encryption as
a hexadecimal number for each key that you wish to encrypt. Make sure that
the values entered in these fields for WEP is identical to the encryption keys
used on the other wireless devices on the network.
33
Instant WirelessTM Series
Wireless PCI Card
The Default Key can then be set by selecting any of the four keys that have been
entered in the Manual Entry fields. That key will then be the one used automatically by the Wireless PCI Card.
ADVANCED
Once you have chosen your key encryption method and entered either the
Passphrase or manual key, click the Apply Changes button Then click the OK
button and the encryption portion of the setup is complete. To undo these
changes, click the Undo Changes button.
Note: Make sure that the values entered in these fields for WEP are identical
to the encryption keys used on the other wireless devices on the network.
You can also restore the card’s default settings by clicking the Restore Defaults
button.
ENCRYPTION
The Site Survey tab will show you that available Access Points and their features. Click on the desired Access Point, then click Connect to connect or
Search to search for more Access Points. Click OK when you are finished.
34
The Advanced tab allows you to set the Fragmentation Threshold, the
RTS/CTS Threshold, and the Preamble Type. The Fragmentation Threshold
Value indicates how much of the network resources are devoted to recovering
packet errors. The value should remain at its default setting of 2,436. If you
experience high packet error rates, you can decrease this value, but it will likely decrease overall network performance. Only minor modifications of this
value are recommended.
The RTS Threshold Value should remain at its default setting of 2,437. A preamble is a signal used to synchronize the transmission timing between two or
more systems. A series of transmission pulses is sent before the data to indicate that "someone is about to transmit data". This ensures that systems receiving the information correctly interpret when the data transmission starts.
Security is used for WEP only. By selecting Deny Unencrypted Data
Frames, all unencrypted data will not be seen. For Authentication Type, you

Shared Key is when both the sender and recipient share a secret key. Both units
use this key for an extended length of time, sometimes indefinitely. Any eavesdropper that discovers the key may decipher all packets until the key is
changed.
Open System, the default setting, is when the sender and the recipient do not
share a secret key. Each party generates its own key-pair and asks the receiver
to accept the (usually randomly) generated key. Once accepted, this key is used
for a short time only, then a new key is generated and agreed upon. Even if the
secret key is discovered, only a small amount of data may be decrypted.

39
Instant WirelessTM Series
Can I play multiplayer games with other members of the wireless network?
Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the game's user guide for more information.
What is IEEE 802.11b standard?
The IEEE 802.11b Wireless LAN standards subcommittee, which is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufacturers to communicate.
What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11b functions:
• CSMA/CA plus Acknowledge protocol
• Multi-Channel Roaming
• Automatic Rate Selection
• RTS/CTS feature
• Fragmentation
• Power Management
What is Ad-Hoc?
An Ad-Hoc wireless LAN is a group of computers, each with a WLAN adapter,
connected as an independent wireless LAN. Ad hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.
What is Infrastructure?
An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers.
What is Roaming?
Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single Access Point. Before using the roaming function, the workstation must
make sure that it is the same channel number with the Access Point of dedicated coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a
number of different functions. Each node and Access Point, for example, must
always acknowledge receipt of each message. Each node must maintain contact
with the wireless network even when not actually transmitting data. Achieving
these functions simultaneously requires a dynamic RF networking technology
that links Access Points and nodes. In such a system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates such
40
Wireless PCI Card
factors as signal strength and quality, as well as the message load currently
being carried by each Access Point and the distance of each Access Point to the
wired backbone. Based on that information, the node next selects the right
Access Point and registers its address. Communications between end node and
host computer can then be transmitted up and down the backbone.
As the user moves on, the end nodes RF transmitter regularly checks the system to determine whether it is in touch with the original Access Point or
whether it should seek a new one. When a node no longer receives acknowledgment from its original Access Point, it undertakes a new search. Upon finding a new Access Point, it then reregisters, and the communication process continues.
What is BSS ID?
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a
BSS must be configured with the same BSS ID.
What is ESS ID?
An Infrastructure configuration could also support roaming capability for
mobile workers. More than one BSS can be configured as an Extended Service
Set (ESS). Users within an ESS could Roam freely between BSSs while served
as a continuous connection to the network wireless stations and Access Points
within an ESS must be configured with the same ESS ID and the same radio
channel.
What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth
for unlicensed use in the ISM (Industrial, Scientific and Medical) band.
Spectrum in the vicinity of 2.4 GHz, in particular, is being made available
worldwide. This presents a truly revolutionary opportunity to place convenient
high-speed wireless capabilities in the hands of users around the globe.
What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability,
integrity, and security. In other words, more bandwidth is consumed than in the
case of narrowband transmission, but the trade off produces a signal that is, in
effect, louder and thus easier to detect, provided that the receiver knows the
parameters of the spread-spectrum signal being broadcast. If a receiver is not
tuned to the right frequency, a spread-spectrum signal looks like background
noise. There are two main alternatives, Direct Sequence Spread Spectrum
(DSSS) and Frequency Hopping Spread Spectrum (FHSS).
41
Instant WirelessTM Series
What is DSSS? What is FHSS? And what are their differences?
Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that
changes frequency in a pattern that is known to both transmitter and receiver.
Properly synchronized, the net effect is to maintain a single logical channel. To
an unintended receiver, FHSS appears to be short-duration impulse noise.
Direct-Sequence Spread-Spectrum (DSSS) generates a redundant bit pattern
for each bit to be transmitted. This bit pattern is called a chip (or chipping
code). The longer the chip, the greater the probability that the original data can
be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original
data without -the need for retransmission. To an unintended receiver, DSSS
appears as low power wideband noise and is rejected (ignored) by most narrowband receivers.
Would the information be intercepted while transmitting on air?
WLAN features two-fold protection in security. On the hardware side, as with
Direct Sequence Spread Spectrum technology, it has the inherent security feature of scrambling. On the software side, WLAN series offer the encryption
function (WEP) to enhance security and Access Control. Users can set it up
depending upon their needs.
Can Instant WirelessTM products support printer sharing?
Instant WirelessTM products perform the same function as LAN products.
Therefore, Instant Wireless™ products can work with NetWare, Windows
2000, or other LAN operating systems to support printer or file sharing.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit
shared key algorithm, as described in the IEEE 802.11b standard.
Wireless PCI Card
Glossary
Ad-hoc Network - An ad-hoc network is a wireless network or other small network in which some of the network devices are part of the network only for the
duration of a communications session while in some close proximity to the rest
of the network.
Default Gateway - The router used to forward all traffic that is not addressed
to a station within the local subnet.
DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network
administrators manage centrally and automate the assignment of Internet
Protocol (IP) addresses in an organization's network. Using the Internet's set of
protocol (TCP/IP), each machine that can connect to the Internet needs a
unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer and,
if computers move to another location in another part of the network, a new IP
address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP
address when a computer is plugged into a different place in the network.
DHCP uses the concept of a "lease" or amount of time that a given IP address
will be valid for a computer. The lease time can vary depending on how long a
user is likely to require the Internet connection at a particular location. It's especially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks
in which there are more computers than there are available IP addresses.
DHCP supports static addresses for computers containing Web servers that
need a permanent IP address.
DNS - The domain name system (DNS) is the way that Internet domain name
are located and translated into Internet Protocol (IP) addresses. A domain name
is a meaningful and easy-to-remember "handle" for an Internet address.
42
43
Instant WirelessTM Series
DSSS - Also known as “Direct Sequence Spread Spectrum”, this is a variety of
radio transmission methods that continuously change frequencies or signal patterns. Direct sequence spread spectrum (DSSS), which is used in CDMA, multiplies the data bits by a very fast pseudo-random bit pattern (PN sequence) that
"spreads" the data into a large coded stream that takes the full bandwidth of the
channel
Dynamic IP Address - An IP address that is automatically assigned to a client
station in a TCP/IP network, typically by a DHCP server. Network devices that
serve multiple users, such as servers and printers, are usually assigned static IP
addresses.
ESS - More than one BSS in a network.
FHSS - Also known as “Frequency Hopping Spread Spectrum”. Frequency
hopping spread spectrum (FHSS) continuously changes the center frequency of
a conventional carrier several times per second according to a pseudo-random
set of channels, while chirp spread spectrum changes the carrier frequency.
Because a fixed frequency is not used, illegal monitoring of spread spectrum
signals is extremely difficult, if not downright impossible depending on the
particular method.
Firmware - Programming that is inserted into programmable read-only memory (programmable read-only memory), thus becoming a permanent part of a
computing device.
IEEE - The Institute of Electrical and Electronics Engineers. The IEEE
describes itself as "the world's largest technical professional society -- promoting the development and application of electrotechnology and allied sciences
for the benefit of humanity, the advancement of the profession, and the wellbeing of our members."

Wireless PCI Card
IP Address - In the most widely installed level of the Internet Protocol (IP)
today, an IP address is a 32-binary digit number that identifies each sender or
receiver of information that is sent in packet across the Internet. When you
request an HTML page or send e-mail, the Internet Protocol part of TCP/IP
includes your IP address in the message (actually, in each of the packets if more
than one is required) and sends it to the IP address that is obtained by looking
up the domain name in the Uniform Resource Locator you requested or in the
e-mail address you're sending a note to. At the other end, the recipient can see
the IP address of the Web page requestor or the e-mail sender and can respond
by sending another message using the IP address it received.
IPCONIFG - A utility that provides for querying, defining and managing IP
addresses within a network. A commonly used utility, under Windows NT and
2000, for configuring networks with static IP addresses.
ISP - An ISP (Internet service provider) is a company that provides individuals
and companies access to the Internet and other related services such as Web site
building and virtual hosting.
LAN - A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
resources of a single processor or server within a small geographic area (for
example, within an office building).
MAC Address - The MAC (Media Access Control) address is your computer's
unique hardware number.
mIRC - mIRC runs under Windows and provides a graphical interface for logging onto IRC servers and listing, joining and leaving channels.
Network Mask - also known as the “Subnet Mask”.
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of journals, has
many local chapters, and several large societies in special areas, such as the
IEEE Computer Society.
PCMCIA - The PCMCIA (Personal Computer Memory Card International
Association) is an industry group organized in 1989 to promote standards for a
credit card-size memory or I/O device that would fit into a personal computer,
usually a notebook or laptop computer.
Infrastructure - An infrastructure network is a wireless network or other small
network in which the wireless network devices are made a part of the network
through the Access Point which connects them to the rest of the network.
Ping - (Packet INternet Groper) An Internet utility used to determine whether
a particular IP address is online. It is used to test and debug a network by sending out a packet and waiting for a response.
45
Instant WirelessTM Series
RJ-45 - A connector similar to a telephone connector that holds up to eight
wires, used for connecting Ethernet devices.
Roaming - The ability to use a wireless device and be able to move from one
access point’s range to another without losing the connection.
Static IP Address - A permanent IP address that is assigned to a node in a
TCP/IP network.
Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets.
TCP (Transmission Control Protocol) - A method (protocol) used along with
the Internet Protocol (Internet Protocol) to send data in the form of message
units between computers over the Internet. While IP takes care of handling the
actual delivery of the data, TCP takes care of keeping track of the individual
units of data (called packet) that a message is divided into for efficient routing
through the Internet.
Wireless PCI Card
UTP - Unshielded twisted pair is the most common kind of copper telephone
wiring. Twisted pair is the ordinary copper wire that connects home and many
business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are
twisted around each other. Each signal on twisted pair requires both wires.
Since some telephone sets or desktop locations require multiple connections,
twisted pair is sometimes installed in two or more pairs, all within a single
cable.
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64bit shared key algorithm, as described in the IEEE 802.11 standard.
WINIPCFG - Configuration utility based on the Win32 API for querying,
defining and managing IP addresses within a network. A commonly used utility, under Windows 95, 98, and Millennium, for configuring networks with
static IP addresses.
TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the
basic communication language or protocol of the Internet. It can also be used
as a communications protocol in a private network (either an intranet or an
extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer
that you may send messages to or get information from also has a copy of
TCP/IP.
UDP (User Datagram Protocol) - A communications method (protocol) that
offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol (IP). UDP is an alternative
to the Transmission Control Protocol (TCP) and, together with IP, is sometimes
referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the
Internet Protocol to actually get a data unit (called a datagram) from one computer to another. Unlike TCP, however, UDP does not provide the service of
dividing a message into packets (datagrams) and reassembling it at the other
end. Specifically, UDP doesn't provide sequencing of the packets that the data
arrives in. This means that the application program that uses UDP must be able
to make sure that the entire message has arrived and is in the right order.
Network applications that want to save processing time because they have very
small data units to exchange (and therefore very little message reassembling to
do) may prefer UDP to TCP.
