Explanation

A touch screen is both an input and output device (or an input/output device).

It is an electronic visual display—often an LCD, AMOLED, or OLED screen

Explanation

The ALU (Arithmetic and Logic Unit) performs the computer's data processing functions.

As a primary component of the CPU, the ALU handles all arithmetic, logic, and shifting operations on data. 

Explanation

1 byte equals 8 bits.

Additional Information

Explanation

• In computers, input, processing, and output are the main functions.
• A song being played represents output, as the computer is producing sound for the user.
• Input would be typing or clicking, processing is computations or data handling.

Additional information:

• Output devices include speakers, monitor, and printer.
• Computers convert processed data into user-friendly form via output.

Explanation

• Memory (RAM): Temporary, volatile, fast access
• Storage (HDD/SSD): Permanent, non-volatile, slower than RAM
• Example Memory: RAM in computers (4GB, 8GB, 16GB)
• Example Storage: Hard disk, SSD (256GB, 512GB, 1TB)
• Purpose: Memory = active tasks, Storage = long-term data

Explanation

A "standalone" computer by definition does not require a network connection to function, as it operates independently. 

A LAN Card (Local Area Network card) is networking hardware used to connect a computer to a network (like the internet or a local office network).

RAM (Random Access Memory) is a crucial component for a computer's basic operation

An operating system (OS) is essential system software that manages the computer's hardware and software resources 

Explanation

An extremely small piece of silicon on which integrated circuits are implemented is called a microchip.

It is also commonly known as an integrated circuit (IC), or simply a chip

It is made of silicon.

Used in computers and electronics.

Controls processing functions.

Explanation

A device that encodes characters by pressing keys is known as a keyboard

ADDITIONAL INFORMATION RELATED TO KEYBOARD

It is an input device.

It is used to enter text and commands.

Each key represents a character or function.

Christopher Latham Sholes was an American inventor who invented the QWERTY keyboard.
