A computer is an electronic machine that can: Accept input, Process input, Produce output:

  1.  Accept input. Note that,  Input could be entered by a human through a keyboard, or received over a network, or provided automatically by sensors attached to the computer.
  2. Execute a set of instructions to process the input data.
  3. Produce output. Output could be data displayed to a human in the form of soft copy output or hard copy output, but it could also be anything that effects the world outside the computer such as electrical signals that control how a device operates.

Today, computers are being used in every field of life. It can be used for different tasks.
It is used for data processing. It is used to calculate or perform some mathematical work. It can be used for word processing, record keeping, listening music, playing computer games etc. And above all, it is being used to access and use Internet, a huge source of information.

    Advantages and Disadvantages of Ring Network Topology

    Topic: Advantages and Disadvantages of Ring Network Topology alongwith detailed working of Ring topology What Do You Mean by Ring Topology? In Ring topology, each computer is connected to the next computer such that last computer is connected to the first. Every computer is connected to next computer in the ring. Each computer retransmits what it receives from the previous computer. Suppose, computer A needs to send data to computer D. Now the computer A sends data to computer B. As computer B is not the destination computer, so it will retransmit data to computer C. Finally, Computer C will transfer data to computer D, the destination computer. When a node sends a message, the message is processed by each computer in the ring. If a computer is not the destination node, it will pass the message to the next node, until the message arrives at its destination. Advantages of Ring Network Topology 1. It is relatively less expensive than a star topology network. 2. In a Rin
