Information Systems Test 3a

Networks are an interconnection of computers and other communication devices that allow multiple users to SHARE:

The 3 parts of the NETWORK SYSTEM ARCHITECTURE:

____________ is when a "centralized computer" is connected to dumb terminals via direct lines and/or through telephone lines.

With TELEPROCESSING,the computer is normally a ___________.

_________ is capable of processing very large business applications efficiently.

Large and medium sized companies relied on ______________ in the 80s and many still do today.

A teleprocessing network's operating system is ______ ______  so it can execute multiple ____________ at the same time.

In a teleprocessing network , the computer is referred to as the _________.

The 4 types of a DISTRIBUTED network are:

In a DISTRIBUTED network, different computers can specialize in different _________.

A _____________ network is when independent computers are connected to each other (mainly microcomputers and workstations).

In a ___________ network, each computer can perform all of it's own tasks or have other computers perform some specialized tasks.

Computers must be within a few thousand feet in a ________ network.

A __________ is a network that covers a city or suburb.

A ________ is a network that covers a large geographical area. Can be made up of several LAN and MAN networks.

A _________ network architecture uses both teleprocessing and distributed. And has the advantages of both.

The two major types of DISTRIBUTED NETWORKS are:

Name the 4 configurations of LAN topology:

Any device on a network that is not a server is called a _________.

A  _________ is a computer that serves the needs of the network only.

A ________ is a device (normally a computer) that connects nodes on a network and is half-duplex.

A ________ is a device (normally a computer) that connects nodes on a network and is full-duplex.

A ______ forwards data it receives to all other nodes.

__________ are a set of communications conventions that are built into the hardware and software (NOS) that govern the exchange of data between computers in a network.

A _________ is a circuit board that connects to the mother board in each computer which connects it to the network.

4 examples of a server are:

________ duplex devices, such as a _____, can't receive and send at the same time.

________ duplex devices, such as a _______, can send and receive at the same time.

A _________ is a computer that connects two LAN Networks with the SAME topology (configuration).

A _________ is a computer that connects two LAN Networks with a DIFFERENT topology (configuration).

A _________ is a computer that directs communications when several networks are connected together.

A switch forwards data only to the ________ that are ________.

In ________ topology, the overall speed of the network is dependent on the processing speed of the HUB.

In __________ topology the central computer (HUB) operates as a clearing house for all the sharing of data and communications.

In _______ topology, each user has its own computer to do their independent processing.

In _______ topology if the central computer is down, then the network is down.

In _______ topology, communications and data are passed through one computer at a time in a circular manner.

In ________ topology, if the connection is broken, then the whole network is down.

Ring topology can be _______/_______ or ______ to _______.

_______ topology is the most reliable of all the LAN topologies.

In _________ toplogy, computers share communication and data by sharing the same communication lines.

In __________ topology, more communications or data may be on the line so faster line speeds are required.

Bus topology can ________/________ or ______ to ______.

The FDDI uses ______ ______ _______ with adaptation of ring topology.

________ is the fastest, most reliable and most expensive LAN.

FDDI uses _______ rings.

The  _______ is an organization's private network.

The ____________ are private intranets that connect not only internal personnel, but also selected suppliers, etc...

__________ are private networks that use the internet to connect remote sites (locations).

A system of hardware and software that blocks unauthorized users inside or outside an organization from entering the intranet is called a ____________.
