relevant authorizations.

A

Management of execution of applications

24
Q

The operating system manages reading and writing in the file system and the user and
application file access authorizations.

A

File Management

25
Q

The operating system provides a certain number of indicators that can be used to
diagnose the correct operation of the machine.

A

Information Management

26
Q

What are the three (3) Components of the Operating System

A
  1. The kernel
  2. The shell
  3. The file system
27
Q

Which represents the operating system’s basic functions such as management of memory, processes, files, main inputs/outputs and communication functionalities.

A

The kernel

28
Q

Allowing communication with the operating system via a control language, letting the user control the peripherals without knowing the characteristics of the hardware used, management of physical addresses,
etc.

A

The shell

29
Q

Allowing files to be recorded in a tree structure.

A

The file system

Q

Seven (7) Categories of Operating System

A
  1. Real-Time OS
  2. Single-user and single-task OS
  3. Single-user and multitask OS
  4. Multi-user O
  5. Network OS
  6. Internet/Web OS
  7. Mobile OS
31
Q

Is installed in special purpose embedded systems like robots, cars, and modems.

A

Real-Time OS

32
Q

Are installed on single-user devices like phones.

A

Single-user and single-task OS

33
Q

Are installed on contemporary personal computers.

A

Single-user and multitask OS

33
Q

Is installed in network environments where many users have to share resources. Server
OSs are examples of multi-user operating systems.

A

Multi-user OS

34
Q

Is used to share resources such as files, printers in a network setup.

A

37
Q

The combination of operating system and processor.

A

Platform

38
Q

It refers to the part of an operating system, program, or service that allows a user to enter and receive information.

A

The User Interface

38
Q

Starting Your Computer

A

The Boot Process

39
Q

What is the origin of the term “boot” in the context of the boot process, and what expression did it inspire?

A

The term “boot” comes from “bootstrap loader,” a small program used to start a larger one. It alludes to bootstraps, leather straps used to pull on boots.

This use of bootstraps led to the expression “pull oneself up by the bootstraps.”

40
Q

The boot process consists of four (4) basic steps:

A
  1. The basic input/output system (BIOS) is activated by powering on the CPU.
  2. The BIOS checks that all attached devices are in place (called a power-on self-test or POST).
  3. The operating system is loaded into RAM.
  4. Configuration and customization settings are checked.
41
Q
