Answer:
Network
Explanation:
A computer network can be defined as a group of computers Linked together in order to share resources and information. The complexity of the network increases with the number of computers to be connected and the geographical location covered. It can be as simple as connecting two computers in a room to trillions of computers in the whole world.
To understand Computer Networks better, the following basics must be known.
1. Networking Devices
These are the devices that help the user link to other computers or devices or even boost the strength of the networks. Examples include bridges, hubs, switches, routers and repeaters.
2. Topology
This explains the logical layout of the computers within the network. Examples include Bus, Star, Ring, Mesh etc.
3. The Medium
These are the channels used to transmit data from one computer/ network to another. The choice of a medium depends on the distance, terrain, affordability and environment. Examples include Fiber optic, coaxial cables, radio waves, twisted pair cable etc.
4. Protocols
These are set of rules or guidelines that are used between two or more communicating devices. Examples :
a. TCP (Transmission Control Protocol ) and UDP ( User Data gram Protocol ) used for transmission of data.
b. SMTP (Simple Mail Transfer Protocols) used for mails
c. FTP (File Transfer Protocols ) used for File Transfers
5. Software
The common software that help in computer networks are mainly the operating system. Example Network Operating System running on the servers, Other operating systems running on the client machines.
In conclusion, Computer Networks are set of computers connected using different media channels, networking devices, protocols and software so as to enhance sharing resources like printers and information.
For cable connection, computers have an Expansion Slot for Network Interface Card that helps in controlling data flow between the computer and other Networks.
