What is a Network?
A computer network is a number of computers linked together to allow them to share resources. Networked computers can share hardware, software and data.
What is the difference between LAN and WAN.
A LAN covers a small area such as one site or building, eg a school or a college, while a WAN covers a large geographical area. Most WANs are made from several LANs connected together.
What is BUS network and why use it?
In a bus network all the workstations, servers and printers are joined to one cable (the bus). At each end of the cable a terminator is fitted to stop signals reflecting back down the bus. It is easy to install and is cheaper than other networks to install.
What is a Disadvantage of the BUS network?
If any part of the cable breaks, then the entire network is broken.
What is Ring network and why use it?
In a ring network each device (workstation, server, printer) is connected to two other devices, this forms a ring for the signals to travel around.This type of network can transfer data quickly, even if there are a large number of devices connected because the data only flows in one direction, so there won't be any data collisions.
What is Star network and why use it?
In a star network each device on the network has its own cable that connects to a switch or hub. A hub sends every packet of data to every device, whereas a switch only sends a packet of data to the destination device. Is very reliable - if one cable or device fails then all the others will continue to work.
