Explanation

An application programming interface is a connection between computers or between computer programs.

It is a type of software interface, offering a service to other pieces of software.

Explanation

An integrated circuit  is a set of electronic circuits on one small flat piece  of semiconductor material, usually silicon.

Large numbers of tiny MOSFETs  integrate into a small chip.

First generation  (1940 - 1956) vacuum tubes as a major piece of technology.

The  ENIAC  is an example of 1st generation computer.

Second generation (1956 - 1963) use of transistors .

Third generation (1964 - 1971) use of  Integrated circuits.

Explanation

Packet switching is used in networks where data is broken into smaller packets before being transmitted.

These packets are sent independently and may take different paths to the destination

This method is efficient and robust, making it the foundation for most modern data networks, including the Internet.

Explanation

Explanation

RAM stands for Random Access Memory

It is the hardware in a computing device where the operating system (OS)

RAM is also known as read/write memory

RAM is located in the Motherboard.

Explanation

The First Mechanical Computer Designed by Charles Babbage was called Analytical Engine.

The English inventor Charles Babbage in the 19th century (he worked on it until his death in 1871).

Explanation

Hard Disk is an example of Magnetic Storage and Secondary storage.

The hard disk was invented on September 13, 1956, by an IBM team led by Rey Johnson

The commercial usage of hard disk drives (HDD) began in 1957

Rey Johnson (considered as “father” of the disk drive).

A computer hard disk drive is a non-volatile data storage device.

Hard Disk is an example of Magnetic Storage

Explanation

The hard disk is a secondary storage device, which is designed to store data permanently.

Note: ROM and RAM are two main types of Primary Storage Device
