Computer Functionality Quiz

The binary number system is a base-2 number system that uses only two digits, 0 and 1, to represent numbers. In digital computers, the binary number system is used to represent and manipulate data and instructions because computers use electronic components that can easily represent and process binary signals.

Binary codes are representations of characters, numbers, or instructions using binary digits. They are used in digital computers to encode and decode information. For example, ASCII (American Standard Code for Information Interchange) and Unicode are binary codes that represent characters in different languages and symbol sets.

Two components of a digital computer are the Central Processing Unit (CPU) and the Memory. The CPU is responsible for executing instructions and performing arithmetic and logical operations. The Memory stores data and instructions that the CPU can access and manipulate.

The CPU (Central Processing Unit) is the brain of a computer. Its main role is to execute instructions and perform calculations. It fetches instructions from memory, decodes them, and then carries out the necessary operations. The CPU also coordinates the activities of other hardware components in the computer.

In a computer, an instruction is a command or a set of commands that tells the CPU what operations to perform. Instructions are encoded in binary form and stored in memory. The CPU fetches instructions, decodes them, and executes them to perform tasks such as arithmetic operations, data manipulation, and control flow.
