Input Device: It allows you to communicate with the computer or to input data, e.g., a keyboard. Storage Device: It permanently stores the data, e.g., hard drive. Motherboard: It is the part that connects all other parts or components of a computer. Memory: It is the primary memory for data transfer between the CPU and storage. Processor: It executes instructions from software and hardware. The basic parts without which a computer cannot work are as follows: Charles Babbage is also known as the father of the computer. It is believed that the Analytical Engine was the first computer which was invented by Charles Babbage in 1837. Whereas, the programs and data are called software. The components of a computer such as machinery that includes wires, transistors, circuits, hard disk are called hardware. It also has a memory that stores the data, programs, and result of processing. It works with the help of programs and represents the decimal numbers through a string of binary digits. The term "computer" is derived from the Latin word "computare" which means to calculate.Ī computer is designed to execute applications and provides a variety of solutions through integrated hardware and software components. It can process numerical as well as non-numerical calculations. 
It renders output just after performing mathematical and logical operations and can save the output for future use.
A computer is a programmable electronic device that accepts raw data as input and processes it with a set of instructions (a program) to produce the result as output.
