A computer can be defined as an electronic device that accepts data from an input device, processes it, stores it in a disk and finally displays it on an output device such as a monitor.
To understand the basic rudiments of the functioning of the computer refer to the all types of computers such as Personal Computers, Laptops, Palmtops etc. In other words, the fundamental principle of working is the same. There are four main building blocks in a computer's functioning. input, processor, output and memory. The data is entered
through input devices like the keyboard, disks or mouse. These input devices help convert data and programs into the language that the computer can process. The data received from the keyboard is processed bythe CPU, i.e. the Central Processing Unit. The CPU controls and manipulates the data that produce information. The CPU is usually housed within the protective cartridge. The processed data is either stored in the memory or sent to the output device, as per thecommand given by the user. The memory unit holds data and program instructions forprocessing data. Output devices translate the processed information from the computer into a form that we can understand.
