Q & A

What is a computer according to the script?

A computer is an electronic device capable of receiving inputs, storing data, manipulating it according to a set of instructions called a program, and producing output in a desired form.

How is computer literacy defined in the script?

Computer literacy is defined as the knowledge and ability to use computers and related technology efficiently, covering a range of skills from elementary use to programming and advanced problem-solving.

What are the four basic steps of CPU operation mentioned in the script?

The four basic steps of CPU operation are fetch, decode, execute, and write back.

What is the primary responsibility of a computer processor?

The primary responsibility of a computer processor is to execute a sequential set of instructions that constitute a program.

Can you describe the function of a motherboard as outlined in the script?

A motherboard consists of sockets for microprocessors, memory slots, a chipset for interfacing CPU bus and peripheral buses, non-volatile memory chips for firmware, and a clock generator for system synchronization. Some also include logic and connectors for input devices.

What is a hard disk and what is its primary function?

A hard disk is a part of the computer disk drive that stores data and provides quick access to large amounts of data. It is an electromagnetically charged surface or set of disks that record data in concentric circles.

What is the capacity range of data storage for a hard disk as mentioned in the script?

Hard disks can store between 120 gigabytes to 2 terabytes of data.

How does computer memory function in collaboration with the CPU?

Computer memory retains digital data and forms the core of a computer, working in collaboration with the CPU to process and store information.

What is the purpose of a monitor in a computer system?

A monitor, also known as a visual display unit, displays images generated by the video output of a computer, providing users with instant feedback in the form of text and graphic images.

Describe the function of a keyboard as an input device for a computer.

A keyboard is an input device with keys that act as electronic switches or mechanical levers, each key press corresponding to a written symbol. It has its own processor and circuitry to facilitate operation.

How does a computer mouse function as a pointing device?

A computer mouse detects two-dimensional motion and translates the motion of a user's hand into signals that a computer can recognize and respond to.
