What is an operating system?

What is an operating system?


Operating system is a program that acts as a medium between the hardware and the consumer of a computer. The primary goal of the operating system is to make the computer system convenient for use and its second goal is to keep the computer hardware running smoothly.
The operating system is a set of programs designed to manage a computer's resources and include starting a computer, managing programs, managing memory, and coordinating tasks between input and output devices. .


  • Operating System required / working

Operating System controls and operates the entire computer. The computer is managed by this. Operating System gives the user the ability to work on the computer easily. The relationship of operating system and computer can be understood through a flow chart.

Some of the major functions of the Operating System are below.


  • The Operating System makes it easy to use the computer properly.
  • The Operating System hides a lot of hardware information from the user, so the user is not confronted with a lot of information.
  • The Operating System provides the user with a simple medium so that they can operate on the computer easily
  • The Operating System acts as an intermediary between the user and the hardware so that the user can easily use the computer and its resources.
  • Managing the computer and its resources is an essential function of the Operating System.

Different Types of Operating System


The Operating System has always been with computers. As the computer developed, so did the Operating System itself. The Operating System is divided into several categories. However, we will know some of the major types of Operating System here.



  1.  Multi-user:- Operating System This operating system allows multiple users to work together. On this operating system, hundreds of users can do their work at a time.
  2. Single-user:- Operating System In contrast, the Single-user Operating System allows only one user to work at a time. Many users cannot work on this operating system at one time.
  3. Multitasking Operating:- System This Operating System allows the user to run several different programs simultaneously. On this operating system, you can also write e-mail at a time and also chat with your friends.
  4. Multi-Processing:- Operating System This Operating System allows a program to run on more than one CPU.
  5. Multi-Threading:- Operating System This Operating System allows different parts of a program to run simultaneously.
  6. Real Time Operating System:- The Real Time Operating System processes the Input given by the user immediately. The Windows Operating System is the best example of this.


Operating system is a very important program for computers. Without it, the computer is just a dead object, it is not wrong to say. Without an operating system, using a computer can prove to be a very difficult task. To understand the relationship of Operating System and Computer, you can understand the above diagram.

Operating System Features

  • Tracks Primary Memory Like, where is it being used? How much memory is being used? And provides memory on demand.
  • It takes care of the processor, that is, manages.
  • Maintains all computers connected devices.
  • The computer manages both hardware and software.
  • Provides security through password and other technologies.
  • Keeps track of the work done by the computer and keeps a record of them.
  • Shows errors and dangers.
  • Creates coordination between User and Computer Programs.

Major Operating System Names


  • Windows os
  • Mac OS
  • Linux OS
  • Ubuntu
  • Android OS
  • iOS
  • Ms-dos
  • Symbian OS

What have you learned?

What is computer keyboard?


Complete Information About Keyboard


Keyboard is an input device. With its help, we give instructions to the computer. The main use of the keyboard is to write text. Apart from this, the keyboard can also be used like a mouse. It is also a multifunctional device, which can not only write but also use the keyboard to control the computer.

The special layout of keys (Keys) on a keyboard is called a keyboard layout. The keyboard layout itself determines the texture, shape and type of the keyboard.

Today various layouts of computer keyboards are available. Different countries of the world have developed keyboard layouts according to their language and script.

We can divide all these keyboard layouts into two broad categories:

  1. QWERTY Keyboard Layout
  2. Non-QWERTY Keyboard Layout


  • QWERTY Keyboard Layout


This is the most popular and used keyboard layout. It has been adopted worldwide. And the same layout is used in modern computer keyboards. Some other Keyboard Layouts based on QWERTY Layout:
  • QWERTY 
  • QWERTZ 
  • AZERTY
  • QZERTY

  • Non-QWERTY Keyboard Layout



Keyboards where QWERTY Layout is not used to set keys are called Non-QWERTY Keyboard. Some Non-QWERTY Keyboard Layouts.

  • Dvork
  • Colemak
  • Workman




Type of Keyboard Keys - Names and types of keys located in the keyboard

The 'QWERTY' Layout is by far the most popular and adopted pattern worldwide. And in this Lesson, you are also told to use this type of keyboard.
Let's know how many Keys in a keyboard? Name and type of keys and what is their use?

A normal keyboard has a total of 104 Keys. And their number also depends on Keyboard Manufactures and Operating System. So broadly we can say that a QWERTY Keyboard has around 100 Keys (±).
Each key in the keyboard has its own special function. And on the basis of this work, they have been divided into the following six categories. Whose description is as follows.

  1. Function keys
  2. Typing keys
  3. Control keys
  4. Navigation Keys
  5. Indicator Lights
  6. Numeric keypad

  • Function Keys


Function Keys is at the top of the keyboard. These are written from F1 to F12 in the keyboard. Function Keys are used to perform a particular task. They have a different function in every program. 

  • Typing Keys

These keys are most commonly used. Typing keys include both types of keys (alphabet and numbers), collectively called Alphanumeric keys. Typing keys also include all types of symbols and punctuation marks.

  • Control Keys


These keys are used alone or with other keys to perform a certain task. In a normal keyboard, most of the Ctrl key, Alt key, Window key, Esc key are used as control keys. Apart from these, keys like Menu key, Scroll key, Pause Break key, PrtScr key etc. are also included in the control keys.

  • Navigation Keys

Navigation keys contain Arrow keys, Home, End, Insert, Page Up, Delete, Page down etc. They are used to move around in any document, webpage etc.  

  • Indicator Lights


There are three types of Indicator light in the keyboard. Num Lock, Scroll Lock and Caps Lock. When the first light in the keyboard is lit, it means that the Numeric Keypad is turned on, and if it is closed it means that the Numeric Keypad is off. Secondly, light indicates to us about Uppercase and Lowercase of letters. When it is closed, the letters are in lowercase, and when it is moving, the letters are in uppercase. The third, known as Scroll Lock. This indicates to us about scrolling.

  • Numeric Keypad

We can also call them Calculator keys, because a numeric keypad has almost the same (some extra) keys as a calculator. They are used to write numbers.


Some of the main Typing Keys and their use

  • Tab Key

Tab is used to give the space of many letters simultaneously. Apart from this, it also has many uses. Tab is also used in some Keyboard Shortcuts.

  • Caps Lock Key

This key is used to write all letters in uppercase. When Caps Lock remains on, all letters will be written in uppercase and in lowercase when off.


  • Shift Keys

Shift keys are used to write letters in uppercase. In addition, Shift Keys are also used to type the top portion of a key.

  • Spacebar Spacebar

Keyboard is the largest key. It is used to move the Cursor one space further.

  • Enter Key

The Enter Key is an important key. It is used to start the next line. When Enter is pressed, the Cursor moves to the beginning of the next line. The Enter key also acts as the 'OK' button.

  • Backspace

Backspace is used to delete the selected text next to the Cursor.


Some of the main control keys and their usage

Understanding What is Inside Your Computer and How it Works


 Computer assocessries

Have you ever looked inside a computer case? Its small parts may look complex, but it is not really mysterious inside the computer case. Here you will understand a little bit more about some basic parts

Motherboard:-
The motherboard is the main circuit board of the computer. It is a thin plate with connectors for CPU, memory, hard drives and optical drives, expansion cards to control video and audio, and connections to your computer's port (such as USB ports). The motherboard connects directly or indirectly to each of the computer's components.

Processor:-
The Central Processing Unit (CPU), also known as the processor, is located on the motherboard in the case of a computer. This is called the brain of the computer. It produces the output by processing the input information.
The CPU is usually two inches of Ceramic Square with a silicon chip. This chip fits into the motherboard's CPU socket, which is covered by a hit sink, which soaks up heat from the CPU.
As you might think, CPU speed and performance is the most important factor that determines how a computer will work.
Processor speed is measured in Megahertz (MHz) or Gigahertz (GHz). Faster processors can execute instruction faster.

RAM:-
RAM is the short-term memory of your system. All the processes running on the computer are temporally stored in RAM.
The more capacity RAM the computer has, the more applications you can work on simultaneously.
This short-term memory disappears when the computer is turned off. If you are working on a Word, spreadsheet, or other type of file, you have to save it to avoid losing it. When you save a file, this data is stored on the hard drive, which acts as a permanent storage.
Speeds of RAM are in Megabytes (MB) or Gigabytes (GB). The more RAM you have, the more things computers can do at the same time.

HDD:-
Hard drives are permanent storage of data. All the data on your computer is stored on it.
IDE hard drives, SATA hard drives and SCSI hard drives are the main types of hard disk or HDD.
Today, hard disks in personal computers have 80GB, 120GB, 160GB, 250GB, 320GB, 500GB, 1TB and 2TB capacities.

Optical Disk:-
Most desktop and notebook computers come with optical drives, which are either a CD / DVD or Blu-ray disc.

SMPS:-
Switched-Mode Power Supply (SMPS) takes AC input from the wall outlet, performs power factor correction and then converts the output to a low voltage DC output. It sends power via cable to the motherboard and other components.
