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.

    What are Different Types of Computer

    Computers can be divided into the following 3 types on the basis of their working mechanism: 1) Analog Computers 2) Digital Computers 3) Hybrid Computers 1. Analog Computers Analog computer is used to measure continuous values. It measures a physical property like voltage, pressure, speed, time and temperature. An analog computer takes input in analog form and gives output in analog form. Its output is usually displayed on a meter or scale. Analog computer has low memory and fewer functions. Analog computer is mainly used in the field of engineering and medicine. Examples include: Examples of Analog Computers include:  1. Thermometer 2. Speedometer 3. Analog clock 2. Digital Computers A digital computer works with digital data. Digital computer uses binary number system. Binary number system consists of only two digits 0 and 1. A digital computer represents data in digital signals. A 0 represents OFF and a 1 represents ON. Digital computer performs a...

    Types Of Network Topology

    Today, we will types of network topology . What is a Network Topology? Definition of Network topology is the shape of the network . It is the physical layout of connected devices in a network. It tells us how a network will look like. Network Topology ( Definition 2) : The way in which the connections are made among all the network entities is called the topology of the network. Network Topology ( Definition 3) :Network topology specifically refers to the physical layout of the network, e.g., the location of the computers and how the cable is run between them. Network Topology ( Definition 4) :The physical topology of a network refers to the configuration of cables, computers, and other peripherals. The characteristics of a network depend upon the network topology selected. types of network topology Explain different types of network Topology Different network topologies are as follows: 1.
