Week 3

hey :) this was the most busy week till now. We have learnt a lot in this week. The lecturer taught us about the software and its components.
Software : The Intangible part of computer is known as Software. We cannot touch Software physically. It tells computer what, how and when to do.
Software is divided into three categories :

• System software
• Application Software
• Programming Language

We all got surprise first that how can a software communicate with computer that what to do and how to do then lecturer taught us that It must be given a detailed list of instructions, called a compute program or software that tells it directly that what it has to do. Then lecturer told us about Operating system functions.

Some Operating System functions are starting and shutting down computer, providing a using interface, managing programs, managing memory, coordinating tasks, configuring devices,monitoring performance,updating software automatically, controlling a network,administering security.

User Interface :The user interface, in the industrial design field of human-machine interaction, is the space where interaction between humans and machines occurs. The goal of interaction between a human and a machine at the user interface is effective operation and control of the machine, and feedback from the machine which aids the operator in making operational decisions

Types of user Interface :

Graphical User Interface ( GUI) : A graphical user interface (GUI) is a type of user Interface that allows users to Interact with electronic devices using images rather than text commands.

Command Line Interface (CLI) : A command-line interface (CLI) is a means of interaction with a computer program where the user (or client) issues commands to a program in the form of successive lines of text (command lines).

Operating System : An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system.
