Реферат: How To Design A Network Essay Research

control data and applications. The network software to be used will consists of computer

programs that establish protocols, or rules, for computers to talk to one another. These

protocols are carried out by sending and receiving formatted instructions of data called packets.

Protocols make logical connections between network applications, d!

irect movement through the physical network, and minimize the possibility of collisions between

packets sent at the same time. Network hardware is made up of the physical components that

connect computers. Two important components that will carry the computer’s signals will be

wires or fiber-optic cables, and the network adapter, which will access the physical media that

links the computers, receives packets from the network software, and transmits instructions and

requests to other computers. Transmitted information is in the form of binary digits, or bits which

the electronic circuitry can process.

The new local area network (LAN) that we are proposing to design will only be a one volume

server. The directory structure for this server will go as follows: There will be a system directory

where the queue holds and services the print jobs prior to being printed. A login will be

established to activate and open a session to the Network Operating System for a user. The

DOS applications available to the public will be Word Perfect, Excel, Power Point, and Lotus

1-2-3. A mail directory will be created for users to be able to send e-mail and also retrieve it.

The users of this directory structure will be focused around the faculty which will be Heinrichs,

Perry, Banerjee, Clapper, and Carland. The faculty will have the rights to the classes that are

taught here at Western Carolina University. These classes will also be used by the students of the

Computer Information Systems program. The applications that will be used by the students and

faculty of CIS will be Salsa, CO!

BOL, Visual Basic, Database applications, Basic, and Visual/IFPS Plus. In these courses faculty

can assign programs or assignments to the students and all they have to do is go to the

appropriate class that they are in and get the homework that is do for that certain class.

The medium used to transmit information will limit the speed of the network, the effective distance

between computer, and the network topology. The coaxial cable will provide transmission

speeds of a few thousand bits per second for long distances and about one-hundred million bits

per second (Mbps) for shorter distances.
