What is digital computer and explain with block diagram?

A digital computer is considered to be a calculating device that can perform arithmetic operations at enormous speed.

It is defined as a device that operates upon information/data..

What is Computer explain its block diagram with all parts?

Computer Block Diagram Mainly computer system consists of three parts, that are central processing unit (CPU), Input Devices, and Output Devices. The Central Processing Unit (CPU) is divided into two parts again: arithmetic logic unit (ALU) and the control unit (CU). The set of instruction is in the form of raw data.

What are the 4 functional parts of computer system?

Taking data and instructions from a user, processing the data as per instructions, and displaying or storing the processed data, are the four major functions of a computer. These functions are also known as the input function, process function, output function, and storage function, respectively.

What are the four functional components of a computer?

A computer consists of five functionally independent main parts input, memory, arithmetic logic unit (ALU), output and control unit. Input device accepts the coded information as source program i.e. high level language.

What type of work can a computer perform?

Artwork: A computer works by combining input, storage, processing, and output. All the main parts of a computer system are involved in one of these four processes. Input: Your keyboard and mouse, for example, are just input units—ways of getting information into your computer that it can process.

Where are digital computers used?

It is used to run everything from spacecraft to factories, healthcare systems to telecommunications, banks to household budgets. Since its invention during World War II, the electronic digital computer has become essential to the economies of the developed world.

How does a computer work 0 and 1?

Binary (or base-2) a numeric system that only uses two digits — 0 and 1. Computers operate in binary, meaning they store data and perform calculations using only zeros and ones. A single binary digit can only represent True (1) or False (0) in boolean logic.

What are the advantages of a digital computer?

The main advantage of Digital computers is that they can store loads of data and it is very accurate. Analog computer is quick and hence fastest. Digital computers are comparatively slower than Analog and this is the main disadvantage.
