Hardware



Hardware represents the physical and tangible components of a computer, i.e. the components that can be seen and touched.
Examples of Hardware are the following −
  • Input devices − keyboard, mouse, etc.
  • Output devices − printer, monitor, etc.
  • Secondary storage devices − Hard disk, CD, DVD, etc.
  • Internal components − CPU, motherboard, RAM, etc.
Computer Hardware

Relationship between Hardware and Software

  • Hardware and software are mutually dependent on each other. Both of them must work together to make a computer produce a useful output.
  • Software cannot be utilized without supporting hardware.
  • Hardware without a set of programs to operate upon cannot be utilized and is useless.
  • To get a particular job done on the computer, relevant software should be loaded into the hardware.
  • Hardware is a one-time expense.
  • Software development is very expensive and is a continuing expense.
  • Different software applications can be loaded on a hardware to run different jobs.
  • A software acts as an interface between the user and the hardware.
  • If the hardware is the 'heart' of a computer system, then the software is its 'soul'. Both are complementary to each other.

Digital Transmission

Data can be represented either in analog or digital form. The computers used the digital form to store the information. Therefore, the data needs to be converted in digital form so that it can be used by a computer. DIGITAL-TO-DIGITAL CONVERSION Digital-to-digital encoding is the representation of digital information by a digital signal. When binary 1s and 0s generated by the computer are translated into a sequence of voltage pulses that can be propagated over a wire, this process is known as digital-to-digital encoding. Digital-to-digital encoding is divided into three categories: Unipolar Encoding Polar Encoding Bipolar Encoding Unipolar Digital transmission system sends the voltage pulses over the medium link such as wire or cable. In most types of encoding, one voltage level represents 0, and another voltage level represents 1. The polarity of each pulse determines whether it is positive or negative. This type of encoding is known as Unipolar encoding as it ...

Computers Types classified by their speed and computing power.

Computers can be broadly classified by their speed and computing power. S.No. Type Specifications 1 PC (Personal Computer) It is a single user computer system having moderately powerful microprocessor 2 Workstation It is also a single user computer system, similar to personal computer however has a more powerful microprocessor. 3 Mini Computer It is a multi-user computer system, capable of supporting hundreds of users simultaneously. 4 Main Frame It is a multi-user computer system, capable of supporting hundreds of users simultaneously. Software technology is different from minicomputer. 5 Supercomputer It is an extremely fast computer, which can execute hundreds of millions of instructions per second.

Connection-oriented and Connection-less Services

Image
Difference between Connection-oriented and Connection-less Services Both  Connection-oriented service and Connection-less service  are used for the connection establishment between two or more than two devices. These type of services are offered by network layer. Connection-oriented service  is related to the telephone system. It includes the connection establishment and connection termination. In connection-oriented service, Handshake method is used to establish the connection between sender and receiver. Connection-less service  is related to the postal system. It does not include any connection establishment and connection termination. Connection-less Service does not give the guarantee of reliability. In this, Packets do not follow same path to reach destination. Difference between Connection-oriented and Connection-less Services: S.NO CONNECTION-ORIENTED SERVICE CONNECTION-LESS SERVICE 1. Connection-oriented service is related to the telephone...
