Networks

Front 1

an interconnection of computers and other communication devices that allow multiple users to share

Back 1

Networks

Front 2

Networks share:

Back 2

1.Hardware
2.Data
3. Communication
4. Software

Front 3

Centralized computer is connected to dumb terminals via direct lines and/or through the telephone lines

Back 3

Teleprocessing

Front 4

Computers must be within a few thousand feet of one another

Back 4

Local Area Network (LAN)

Front 5

communications network covering a city or suburb

Back 5

Metropolitan Area Network (MAN)

Front 6

)- A network that covers a wide geographic area (state, country, or the world)

Back 6

Wide Area Network (WAN)

Front 7

Each computer can perform all of its own tasks or have other computers perform some specialized tasks

Back 7

Distributed

Front 8

A network that uses both teleprocessing and distributed and has advantages of both

Back 8

Hybrid

Front 9

Two major types of LAN's

Back 9

Peer-to-peer and Client Server

Front 10

. Consists of individuals using microcomputers and more powerful microcomputers or workstations computers that provide dedicated services for the LAN network

Back 10

Client Server LAN

Front 11

All the microcomputers on the network communicate directly with one another without relying on a server

Back 11

Peer-to-peer LAN

Front 12

4 LAN Topologies

Back 12

Star, bus, ring, FDDI

Front 13

Central computer (Hub) operates as clearing house for all sharing of data and communications

Back 13

Star topology

Front 14

communications and data are passed through one computer at a time in a circular manner; if the connection is broken then the whole network is down

Back 14

Ring topology

Front 15

Computers share communications and data by sharing the same communication lines

Back 15

Bus topology
