modification of packet is done in the order of packet arrival, which increases the reliability of data
transmission between two computers.
TCP/IP (Transmission Control Protocol/Internet Protocol)
These two protocols were developed by
the
U.S. military to allow computers to talk to each other over long distance networks. IP is
responsible for moving packets of data between nodes. TCP is responsible for verifying delivery from
client to server. TCP/IP forms the basis of the Internet, and is built into every common modern
operating system (including all flavors of Unix, the Mac OS, and the latest versions of Windows). .
TELNET
Telnet, developed as a service for ARPANET, is an application that lets you log on to a Unix computer.
Provided you have an account on that Telnet server, you can then use its resources. A drawback of
Telnet is that it's character-based, so you need to speak Unix to the other computer. It is in wide use
for TCP/IP-based Internet.

UDP (User Datagram Protocol)
Protocol basing TCP/IP, standard Internet protocol. In TCP/IP model, data trasmission is done through
the combination of IP, network layer protocol(OSI third layer), TCP, transmission control protocol or
UDP. While communication begins after session is set up, UPD does not include session set-up
procedure, which means faster transmission. But, there is no function such as error packet correction
or re-transmission as TCP does. UDP is adopted by multimedia application that requires high speed
rather than reliabilty.
URL (Uniform Resource Locator)
URLs are the Internet equivalent of standardized logical addresses. It is made up of protoco, host
name, address, and directory location. For example, http://www.nasdisk.com/index.html, or
ftp://ftp.nasdisk.com/pub/public.zip.
VDSL (Very high-Data rate digital Subscriber Line)
VDSL (Very high data rate Digital Subscriber Line) is a type of broadband transport technology for
twisted-pair access operating at data rates from 12.9 to 52.8 Mbps with corresponding maximum
reach ranging from 4500 feet to 1000 feet of 24 gauge twisted pair. VDSL is the most promising
technology capable of delivering full service today is for service providers. VDSL is both symmetric
and asymmetric and provides up to 52 Mbps of bandwidth, over voice, on a single twisted pair copper
loop. VDSL technology provides the service provider with the ability to create the type of business that
is critical for success in the new millennium. Those service providers that can deliver full narrowband
and broadband services consisting of voice, data, and video - including interactive TV - will be the
