UGA NMIX 2020 Networks 100% Verified!!
Computer network - ANSWER a network (wired or wireless) of computers to share
information with each other
Node - ANSWER An endpoint or redistribution point of where data is sent (data being
sent directly to one computer and stopping there, or being sent to many different
computers)
DARPANET - ANSWER Advanced Research Projects Agency Network, created in 1969
that connected four computers into a network using TCP/IP for the first time
The four colleges involved in DARPANET - ANSWER UCLA, Stanford, UC- Santa
Barbara, University of Utah
TCP/IP - ANSWER Transmission Control Protocol/ Internet Protocol - allows two or
more computers to communicate with each other. Robert Kahn, Vint Cerf created it
Protocol - ANSWER A system of rules for how something (in this case a computer)
should behave
Metcalfe's Law - ANSWER Outlined in a 1973 Memo that outlined a theory saying that
the value of a communications network is proportional to the square of the number of
connected users of the system
Tim Berners Lee - ANSWER British guy who "created" the World Wide Web (NOT
internet) working at CERN in 1991 on a NeXT computer
LAN/WAN/MAN - ANSWER Local Area Network, interconnects computers within a
limited area. ETHERNET cable best example of this.
, WAN and MAN - wide area network and metropolitan area network. These just define
how big of a computer network. LAN smallest, WAN largest, and MAN in the middle in
terms of size
Dial Up Internet - ANSWER Uses the existing telephone lines to use the Internet. Has
the slowest internet speeds in kilobits/second, but often still found in very rural places
Broadband Internet - ANSWER Uses a router and modem to connect to the Internet
through an ISP, gives speeds of 10s to 100s of megabytes/second.
Fiber Optics - ANSWER Newest way to connect to Internet, transmits data through
copper wires at the speed of light. Allows for gigabit/second Internet, but requires new
wiring which is very expensive and not many companies are doing this right now
They're more commonly found on the floor of the ocean, which allows for fast data
connection across the continents, to data centers around the world
Minitel - ANSWER Introduced in 1978, first computer everyone could really access and
it was quite successful - connects to your phone line, and you could access a phone
directory, message boards, databases, and even buy things off catalogs and have it ship
to your home!
Internet - ANSWER The network of computers that communicate with each other
Router - ANSWER Allows multiple computers to get on the same network and ensures
that the data that comes through the modem gets to the right device
Modem - ANSWER This is the thing that actually physically connects to the ISP, and
then sends the data it gets to the router. The router and modem are often now in one box
ISP - ANSWER Internet Service Provider - this is your Comcast/Dish/AT&T, etc. They
