Study Notes

What is Software?

Software is a collection of instructions, data, or computer programs that run machines and carry out specific activities.
Software refers to a device's running programs, scripts, and applications.
It is the antithesis of hardware, which refers to a computer's external components.

Types of Software

System Software

System software operates the computer hardware and provides basic functionality to users and other software.
It controls a computer's internal functioning and hardware devices such as monitors, printers, and storage devices.
Examples of system software include Operating Systems (OS) like Linux, Apple macOS, and Microsoft Windows.
The OS is the main program of a computer system, managing resources like computer memory, CPU, printer, and hard disk, and providing an interface to the user.
Language Processors convert human-readable language into machine language and vice versa.
Device Drivers are programs that control devices and help them perform their functions.

Features of System Software

Closer to the computer system.
Written in a low-level language in general.
Difficult to design and understand.
Fast in speed (working speed).
Less interactive for users in comparison to application software.

Application Software

General Purpose Software: used for a variety of tasks, e.g., MS-Word, MS-Excel, PowerPoint.
Customized Software: designed to perform specific tasks or functions for specific organizations, e.g., railway reservation system, airline reservation system.
Utility Software: used to support computer infrastructure, e.g., antivirus, disk fragmenter, memory tester.

Features of Application Software

Performs more specialized tasks like word processing, spreadsheets, email.
Requires more storage space.
More interactive for users, making it easy to use and design.
Easy to design and understand.
Written in a high-level language in general.

Characteristics of Software

Reliability: ability to consistently perform intended tasks without failures or errors.
Usability: how easily and effectively users can interact with and navigate through the software.
Efficiency: optimal utilization of system resources to perform tasks on time.
Maintainability: how easily and cost-effectively software can be modified, updated, or extended.
Portability: ability to run on different platforms or environments without significant modifications.

This quiz covers the definition of software, including a collection of instructions, data, or computer programs used to run machines and carry out activities. It also explains the difference between software and hardware. System software is discussed as a type of software.
