Backbone
The
network of connections and high-speed lines that forms the
infrastructure of the Internet. An important consideration
in choosing a Web site host is that host's proximity to the
backbone. The less network distance between your provider
and the backbone, the faster and more reliable your Web site
will be.
Bandwidth
The
total amount of data that can be sent through a network connection
in a certain time, usually measured in bits per second (bps),
megabits per second (Mbps), or gigabits per second (Gbps).
The bandwidth provides for a faster loading time for your
web site. It is also important because most web hosts only
allow a fixed amount of bandwidth each month. Going over the
limit can be costly. Be sure to know your exact bandwidth
limitations.
Baud
Unit
of signaling speed equal to the number of discrete signal
elements transmited per second. Baud is synonymous with bits
per second (bps). In common usage the baud rate of a modem
is how many bits it can send or receive per second. Technically,
baud is the number of times per second that the carrier signal
shifts value - for example a 1200 bit-per-second modem actually
runs at 300 baud, but it moves 4 bits per baud (4 x 300 =
1200 bits per second).
Binary
Data
represented in binary format uses only two digits - 0 and
1.
binary
mode
FTP
client mode used to transfer binary files (multimedia files,
executables and other data files). Not suitable for transferring
normal text files.
Bit
Every
computer uses an instruction set that is composed of a series
of "bits" or "on-off" signals that are usually represented
by a "1" or a "0." A bit can be thought of a single instruction
that tells a computer processor whether it is "on" or "off."
Think off this like the relationship between a light bulb
and a light switch -- when the switch is up, the light is
on, and when it is down, the light is off. A computer language
combines a series of "bits" into "bytes" and provides an instruction
set that tells a computer processor what to do. .
Bit
rate
The
speed at which bits are transmitted over a communication link.
Expressed in bits per second (bps).
Byte
A
byte is composed of 8 bits or "on-off" signals. You can think
of a byte as being the computer representation for a letter,
like "A," a number like "7," or an instruction to multiply
two numbers, like "3 * 6." For the purposes of creating a
Web site, the number of bytes will measure the size of your
site in terms of disk space. For instance, if your Web hosting
plan allows you to publish a 2 MB (Megabytes or million bytes)
Web site, then essentially it can be made up of 2 million
characters or instructions.
Burst
In
web hosting, burst is when a client suddenly uses more bandwidth
than is expected under its contract.Typically, the web hosting
company expects this to happen occasionally and has set fees
for the client depending on the bandwidth used.
Bridge
A
network device used to connect two LANs using different cabling.
Broadcast
Sending
a packet to all machines on the network.
Browser
Computer
program that allows to search the World Wide Web and displays
the content of the webpages. Examples are Mosaic, Netscape,
Mozilla, Opera and Internet Explorer.
Browser
sniffing
The
process in which the web site tries to determine what kind
of web browser the user is using. This is done to suit the
website to the particular capabilities of the browser.
Bps
(Bits-Per-Second)
-- A measurement of how fast data is moved from one place
to another. A 28.8 modem can move 28,800 bits per second.
