Basic Knowledge Test On Computer! Trivia Quiz

1. CPU stands for.....

Contact Processing Utilities

Central Processing Unit

Central Processing Utopia

The correct answer is "Central Processing Unit". The CPU is the primary component of a computer that carries out the instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations. It is often referred to as the "brain" of the computer, as it interprets and executes instructions, performs calculations, and manages the flow of data within the computer system.

2. Software is a physical thing.

True

False

Software is not a physical thing, but rather a collection of instructions and data that can be stored and executed by a computer. Unlike physical objects, software exists in a digital form and can be easily copied and distributed without any loss of quality.

3. A computer can work without an operating system.

True

False

A computer cannot work without an operating system. The operating system is responsible for managing the computer's hardware, coordinating the execution of software programs, and providing a user interface. Without an operating system, the computer would not be able to perform basic functions or run any software applications. Therefore, the statement that a computer can work without an operating system is false.

4. Main memory is made up of 2 types. Which are these?

Read access memory and read-only memory

Read-only memory and hardisk memory

Hardrive and cd drive memory

The correct answer is read access memory and read-only memory. Main memory, also known as primary memory, is made up of these two types of memory. Read access memory (RAM) is a type of volatile memory that stores data that can be read from and written to by the computer's processor. It is used to temporarily store data that is actively being used by the computer. On the other hand, read-only memory (ROM) is a type of non-volatile memory that stores data that cannot be modified or erased. It contains firmware or software instructions that are permanently stored and used by the computer during startup.

5. RAM is a volatile storage device.

True

False

RAM stands for Random Access Memory, and it is indeed a volatile storage device. Volatile means that the data stored in RAM is temporary and gets erased when the power supply is interrupted or turned off. This is in contrast to non-volatile storage devices like hard drives or solid-state drives, where the data remains even when power is not supplied. RAM is used by computers to store data that is actively being used by the CPU, allowing for faster access compared to non-volatile storage devices.
