Information is data formatted in a manner that allows it to be utilized by human beings in some significant way.
Example of Information:

Central Processing Unit:
After receiving data and commands from the user, a computer system has to process the instructions provided using Central Processing Unit (CPU). It has three elements:

(a) Arithmetic and Logic Unit: An arithmetic logic unit (ALU) is a major component of the central processing unit of a computer system. It does all processes related to arithmetic and logic operations like add, subtract, multiply, etc.

(b) Control Unit: The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor. It tells the computer’s memory, arithmetic, and logic unit, and input and output devices how to respond to the instructions that have been sent to the processor.

(c) Memory Unit: A memory unit is the amount of data that can be stored in the storage unit. Once the data has been entered using input devices, the system stores the data in the memory unit.

Types of Memory: Primary Memory & Secondary Memory.

Output Unit:
An output device is any device used to send data from a computer to another device or user. Most computer data output that is ‘meant for humans is in the form of audio or video. Thus, most output devices used by humans are in these categories. Examples include monitors, projectors, speakers.

RAM: It stands for Random Access Memory. RAM is known as reading/write memory. It is the main memory of the computer system. The information stored in this memory is lost as the power supply to the computer is switched off, so it is also called as “Volatile Memory”.

ROM: It stands for Read-Only Memory. ROM is permanent memory. The content is not lost when the power supply is switched off. ROM cannot be overwritten by the computer, so it is also called “Non-Volatile Memory”.
