Explanation

An integrated circuit is a small chip of semiconductor material, typically silicon, that contains numerous tiny MOSFETs.

The five generations of computers:

1. First Generation (1946-1959 or 1940-1956): Vacuum tube-based technology (e.g., ENIAC).
2. Second Generation (1959-1965 or 1956-1963): Transistor-based technology.
3. Third Generation (1965-1971 or 1964-1971): Integrated circuit-based technology.
4. Fourth Generation (1972-1980): VLSI microprocessor-based technology.
5. Fifth Generation (1980-present): ULSI microprocessor-based technology, with a focus on artificial intelligence.

Explanation

The ALU (Arithmetic Logic Unit) is a component of the processor that consists of both the Logic Unit (LU) and the Arithmetic Unit (AU).

It performs arithmetic and logical operations essential for processing data.

Explanation

Software is a set of computer programs and associated documentation and data.

This is in contrast to hardware, from which the system is built and which actually performs the work.

Explanation

The list of coded instructions is called a Computer program.

Explanation

The size of information in the computer is measured in Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB).

1024 kilobytes (KB) is equal to 1 megabyte (MB).

One Megabyte (MB) = 1024 Kilobytes (KB

One Gigabyte (GB) =  1024 Megabytes MB

One Terabyte (TB)= 1024 gigabytes (GB).

Explanation

EEPROM Stand for Electrically erasable programmable read-only memory.

EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge.

EEPROM is similar to Flash Memory

Explanation

The main memory of a computer is also known by several names, including:

• Primary storage
• Internal memory
• Primary memory
• Main storage
• Random Access Memory (RAM)

All these terms refer to the computer's volatile memory, which temporarily stores data and programs that are currently being used or processed by the CPU (Central Processing Unit).

RAM is a primary memory.

ROM is a primary memory.

RAM stands for: Random Access Memory

ROM stands for: Read Only Memory
