Explanation

A compiler is system software that translates the entire high-level language source code into machine-level object code at once.

It checks for errors during translation and produces a separate executable file.

Explanation

Computers are fast (Speed), precise (Accuracy), and dependable (Reliability).

These qualities make their use attractive in various tasks.

Explanation

Line spacing determines the amount of vertical space between lines of text in a paragraph.

By default, lines are single-spaced, meaning that the spacing accommodates the largest font in that line, plus a small amount of extra space.

Explanation

The third generation of computers (roughly 1964-1971)

It is associated with the development and widespread use of integrated circuits (ICs),

They allowed for smaller, faster, and more powerful computers.

This era also saw the emergence of online real-time systems, making them a defining characteristic of this generation. 

Explanation

UNIX is an operating system that was originally AT&T.

UNIX development started in 1969 at the Bell Labs research center by Ken Thompson and Dennis Ritchie.

UNIX was widely used for Internet servers, workstations, and mainframe computers.

Explanation

A Realtime operating system (RTOS) is designed to respond immediately to external events.

It is used in systems like aircraft controls, medical devices, and industrial machines, where delays can be critical.

Explanation

Explanation

From Third generation operating systems were developed.

The period of third generation was from 1965-1971.

The computers of third generation used Integrated Circuits (ICs) in place of transistors.

A single IC has many transistors, resistors, and capacitors along with the associated circuitry.

The IC was invented by Jack Kilby.
