What is Digital Computer? Features, Examples, Uses and Difference Between Digital and Analog Computer.

Digital Computer examples are one of the wonders of modern technology; computers have become very important in today’s world. Majorly computers have been divided into three depending upon application: Analog computer, Digital computer, and Hybrid computer.

Today in this article, we will uncover Digital Computers which are being used in abundance at present. Let’s get to know ‘What digital Computer?’ examples are and ‘What the difference between digital and analog computers.

Digital Computer, What is it?

Digital computers are built to bring the solutions of equations to an almost unlimited precision, but in a bit slow manner compared to analog computers.

They all have similar components for receiving, processing, sorting, and transmitting data and using a relatively small number of essential functions to perform their tasks.

As its name suggests, a digital computer represents the digital computer’s letters, numerical values, or any other special symbols. This computer is the computer that calculates the number for processing the data.

The inputs and outputs of these computers are binary code i.e., and they use 0 and 1 (binary numbers) for computer operation. The accuracy of these computers is 100%. Digital computers understand machine languages only.

It performs all operations related to computer calculations by adding data. After that, the computer simultaneously takes the required data as input and then performs the calculations and mathematical functions on them and simultaneously provides the results on the monitor screen as an output.

Digital computers use discrete electrical signals for operation rather than continuous electrical signals that made the most common form of computers today because of their versatility, speed, and power.

While analog computers are examples of non-digital computers, they can be electronic computers, and mechanical computers are examples of non-electronic computers (which may or may not be digital).

An example of a computer that is both Non-Digital and Non-Electronic is the ancient Antikythera system found in Greece. Digital computers mainly represent the 5th generation of computers.

Features of Digital Computers

Digital computers are general-purpose machines, i.e., they can solve virtually all kinds of problems. These computers have a large internal memory, where millions of characters can be entered.

Digital computers are used to process both numeric as well as non-numeric data.

It can also perform many arithmetic operations such as addition, subtraction, multiplication, division, and logical operations. It is necessary to have a good enough knowledge of programming to work on these types of computers.

Digital Computers are suitable for solving many problems, and therefore are very popular. They are commonly used in all places. Such as at the home, office, shop, railway, hotel too, etc. Other applications include business, banking, education, entertainment, etc.

These computers are precise because they provide the exact answer to a specific problem. Most of the computers which are available at present are all digital computers. Read all the essential features of computers.

Working of Digital Computer in simple Terms :

Digital computers work in four steps.

  1. Reads input,
  2. Save the input to the memory,
  3. Processing data,
  4. Provides the Output.

Examples of Digital Computers

  • Personal Computers (Desktops and Laptops),
  • Smartphones, and Tablets,
  • Calculators,
  • Digital Weighing Machine,
  • Accounting machines,
  • Digital clock,
  • ATM (Automated Teller Machine).

Uses of Digital computer

  • Scientific research: Digital devices are used to solve mathematical calculations, numerical counts, etc.
  • Technical applications: these are applications where digital tools are used to facilitate engineering designs, drawing plans, commercial product designs, etc.
  • Control systems: consist of remote control mechanisms designed for use in private and industrial homes. Such as electrical appliances, turning the lights on or off, defrosting the refrigerator, regulating the heating or air conditioning, starting the coffee maker, etc.

Advantages of Digital Computer

  • Digital systems have made possible many industrial, scientific, and commercial advances that would have been unattainable otherwise.
  • Information or data can easily store in digital computer systems as compared to analog ones. Also, many additional features and units can often be added to a digital system more efficiently.
  • If we talk about results, then digital computers provide more accurate results than analog computers but, Analog computers are much faster than digital ones.
  • Other merits of digital computers are more reliability, flexibility, versatility, compatibility, less expensive, and ease to control.

Disadvantages of Digital Computers

  • Digital systems consume more energy than analog circuits to accomplish the tasks, thus producing more heat.
  • The Digital circuits are often fragile. If a single piece of digital data is lost or misinterpreted, the meaning of large blocks of related data can completely change.
  • Digital computers manipulate discrete elements of information by using a machine language (binary code).
