CIS 105 Survey of Computer Information Systems

• Essential Concepts and Terminology
• Study Unit 10

2
Synergism.

• The simultaneous action of separate agencies
  which, together, have a greater total effect than
  their separate effects.

3
Computer Network.

• A collection of computers and related devices,
  connected in a way that allows them to share
  data, hardware, and software.

4
Terminal.

• A device with a keyboard and a monitor, used for
  input and output, but not for processing.

5
Local Area Network (LAN).

• An interconnected group of computers and
  peripherals located within a relatively limited
  area, such as building or a campus.

6
Network Version Software.

• Applications designed for installation on a file
  server and made available to more than one user
  at a time.

7
Groupware.

• Software that provides ways for multiple users to
  collaborate on a project, usually through a pool
  of data that can be shared by members of the
  workgroup.

8
Circuit Switching.

• The method of establishing an end-to-end connect
  between computers for the duration of a data
  transmission.

9
Packet Switching.

• A technology employed by data communications
  networks, such as the Internet, whereby a message
  is divided into smaller transmission units called
  packets.

10
Router.

• A computer at an intersection on a
  packet-switching network that examines IP
  addresses and forwards the data towards its
  destination on the least congested path.

11
Protocol.

• In data communication and networking, a
  specifying standard governing data format and
  transmission rules.

12
Protocol Suite.

• The total collection of protocols that define how
  a specific network's functions. Networks can
  employ dozens of protocols.

13
Protocol Stack.

• A network architecture concept that describes the
  sequence of data handling, between the user and
  the physical media, by a series of protocols.

14
Network Interface Card (NIC) .

• A circuit board that enables sending and
  receiving data on a network.

15
Workstation.

• A computer connected to a local area network.

16
Node.

• Each device on a network, including workstations,
  servers, printers, and other peripherals.

17
Client/Server Network.

• A network with workstations (clients) and one or
  more the servers.

18
File Server.

• In client/server computing, a high-capacity,
  high-speed computer dedicated to making files
  and programs available to client workstations and
  nodes.

19
Clients.

• In network computing, all the workstations that
  connect to and send requests to a server.

20
Topology.

• The physical layout of a network. The pattern of
  communications pathways, such as star, bus, and
  ring.

21
Collision.

• A disruption of communication that occurs when
  two packets are sent at the same time.
  Corruption of data caused by simultaneous
  transmission.

22
Ethernet.

• A LAN standard in which network nodes are
  connected by coaxial cable or twisted-pair wire.
  The most popular network architecture, capable of
  transmitting data at 10 Mbps to 1 Gbps.

23
Electronic Data Interchange (EDI).

• A set of business-to-business standards to
  facilitate paperless financial transactions.
