What are the three basic operations of a computer?
Memory Unit: Computer is used to store data and Instructions. Arithmetic Logic Unit (ALU): The major operations performed by the ALU are addition, subtraction, multiplication, division, logic and comparison. Output: This is the process of producing results from the data for getting useful information.

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.
Who control all activities of computer?
Answer: An operating system controls all the activities of a computer.
What controls the computer memory?
The control unit of the central processing unit regulates and integrates the operations of the computer. It selects and retrieves instructions from the main memory in proper sequence and interprets them so as to activate the other functional elements of the system at the appropriate moment…

What controls all parts of a computer system?
The Central Processing Unit (CPU) is called “the brain of computer” as it controls operation of all parts of computer. It consists of two components: Arithmetic Logic Unit (ALU), and Control Unit.
What is a control device in computer?
Control devices are output devices which work together with sensors. Remember – Sensors gather ‘measurable’ data from the environment and input it into a computer. They do not need any human involvement. Sensors typically gather data such as temperature, pressure, pH etc.
Does the operating system control the computer’s memory?
An operating system is the most important software that runs on a computer. It manages the computer’s memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer’s language.
What are two basic tasks of control unit?
The work of the control unit is to direct the flow of data or instructions for the execution by the processor of a computer. It controls, manages and co-ordinates main memory, ALU, registers, input, and output units. It fetches the instructions and generates control signals for the execution.
How do computers work at the most basic level?
The most basic way of thinking of a computer is as an Input/Output machine.So yes, on a very fundamental level all a computer understands is 1’s and 0’s which means that every single input and output gets at some point translated into or from 1’s and 0s.
