OPERATING SYSTEM PART-1 ( CUI & GUI)

                               INTRODUCTION OF OPERATING SYSTEM
An operating system is a program that acts as an intermediary between a user and the computer hardware. The purpose of an operating system is to provide an environment in which a user can execute programs in a convenient and efficient manner. The operating system must ensure the correct operation of the computer system must ensure the correct operation of the computer system . To prevent user programs from interfering with the proper operation of the system, the hardware must provide appropriate mechanisms to ensure such proper behavior.

TYPES OF OPERATING SYSTEM 


1.CUI :  CHARACTER USER INTERFACE


2.GUI:  GRAPHICAL USER INTERFACE



👉   Definition of CUI

CUI is the acronym used for Character User  Interface, which are conventional interfaces extensively used in 1980’s. A command-line interface (CUI) allows users to write commands in a terminal or console window to communicate with an operating system. It is a medium where users respond to a visual prompt by writing a command and receive a response back from the system. Users have to type command or train of command to perform a task. CUI’s are more accurate than GUI’s, but it requires mastery over the commands and syntax. It emphasizes over cognitive process as a primary task. CUI is appropriate for the costly computing where input precision is the priority.

Drawbacks of CUI


  • CLI is suitable for the user who uses it in a regular basis and can memorize the range of commands and options.
  • Mistyping could result in complete chaos.
  • The commands can never be intuitive.
  • These are suitable for modelling not for the interactive graphics.

 ðŸ‘‰    Definition of GUI


GUI expands to Graphical User Interface. A GUI uses graphics to allow users to intercommunicate with the operating system or application. GUI provides windows, scrollbars, buttons, wizards, iconic images, other icons to facilitate users. It is an easy-to-use interface for the novice users. It is intuitive, easy to learn and reduces cognitive load. Unlike CLI, GUI users need not to remember commands rather it requires recognition and good exploratory analysis and graphics.

Drawbacks of GUI
  • Lack of precision.
  • Analysis replication and retracing of steps is hard.
  • Not suitable for modelling.
  • Difficult to design.





                           ðŸ‘‰ Difference Between CUI & GUI


CHARACTER USER INTERFACE: 

1. Basic  : Command line Interface enables a user to communicate with the system through commands.

2.Device : Keyboard

3.Ease of Performing Tasks: Hard to perform an operation and expertise.

4.Flexibility:  Intransigent 

5.Memory Consumption : Low

6.Appearance: Can't be changed

7.Speed: Fast

8.Integration & Extensibility:  Scope of potential improvements.

GRAPHICAL USER INTERFACE: 

1.Basic : Graphical User Interface permits a user to interact with the system by using graphics which includes images, icons etc.

 2.Device : Mouse & Keyboard

3.Ease of Performing Tasks: Ease to perform tasks and does not require expertise.

4.Flexibility: More Flexible

5.Memory Consumption : High

6.Appearance: Custom changes can be employed

7.Speed: Slow

8.Integration & Extensibility:   Bounded

CHARACTERISTICS OF A COMPUTER & CENTRAL PROCESSING UNIT (C.P.U)

Hello, Readers This Blog will help you understand the Characteristics of Computer & About C.P.U (Central Processing Unit ). Characteristic means Computer capabilities i.e Characteristics of Computer  1.Speed 2.Accuracy 3.Consistency 4. Data Storing Capability 5.Flexibility  A. Speed : A Computer is a very fast device .It can perform , in a few Second ,the amount of work that a human being can do in an entire year working round the clock .The speed of the computer is usually 2 to 4 GHz . A powerful computer is capable of performing  about 10 to 40 million arithmetic calculations in a second. or We can say that Computer speed is measured in   megahertz (MHz) or gigahertz (GHz). One Megahertz equals to one million ticks per second,one Gigahertz equals one billion ticks per second . B. Accuracy : The accuracy of a Computer is consistently high an the degree o accuracy of a particular task is 100% accurate.In  a every computer each and e...
