Adapter –
Electronic circuitry that converts one form of input to a different form
of output so that it fits for your PC or Gateway.
Examples
are Power Adapter,
Ethernet Adapter, and DSL Adapter.
Backbone –
The part of a network that connects many systems and networks
and handles high volume of data.
Bit –
binary digit with values 0 or 1 in the binary numbering system.
Boot –
When your Gateway or PC is powered on, the built-in instructions in a
ROM chip that are automatically executed to search and load operating system
and pass control to it.
Bridge –
A device that provides connectivity between different networks.
Broadband Connection –
Media that offers higher bandwidth that has capability
to allow voice, video and data transmission. Now a days, Cable television network
and Digital Subscriber Line (DSL) do offer residential broadband connections.
Browser -
A browser is an application program that allows the user to browse
through the web pages on your PC. For example, the browser can be used to look
at web (html, shtml, xml) pages and download files that are available using FTP.
Cable Modem –
A device that connects a computer to its Ethernet port and then
to Internet through the Cable TV network. Once connected, cable modem users
have a continuous connection to the Internet. Cable modems support bandwidth
of 36 Mbps downstream (from the Internet to the computer), and from 200 Kbps
to 2 Mbps upstream (from the computer to the Internet).
CAT 5 cable –
ANSI/EIA (American National Standards Institute/Electronic
Industries Association) Standard 568 is one of standards that specify
"CATegories" of twisted pair cabling systems (wires, junctions, and connectors) in
terms of the data rates that they can sustain. CAT 5 cable has a maximum
throughput of 100 Mbps and is usually utilized for 100BaseTX networks.
Data Packet –
It is a collection of bits sent over a network at once. For example,
an Ethernet packet can be from 64 to 1518 bytes in length.
DDNS –
Dynamic Domain Name System allows a network device with a dynamic
Internet IP address to have a fixed host and domain name, such as
abcd.mydomain.com. It is useful when you are hosting your own website, FTP
server, or other server behind a router, so people can find your site no matter
how often the Internet IP address changes. Using DDNS requires registering with
a DDNS service provider on the Internet.
Default Gateway –
The routing device used to forward all traffic that is not
addressed to a station within the local subnet.
Denial of Service –
When an attacker floods packets continuously to occupy the
network bandwidth, your PC will not be able to respond to any other service
requests. This leads to Denial of Service. The attack is called Denial of Service
attack.
DES –
Data Encryption Standard, a standard by which sender and receiver use a
shared secret key to encrypt or decrypt the data. The key length used is 56-bits
in this standard.
