Here are most tips you need to know about Computer Software
Software is a set of programs, which is designed to perform a well-defined function. A program is a sequence of instructions written to solve a particular problem.
There are two types of software
Software, instructions that tell a computer what to do. Software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system. The term was coined to differentiate these instructions from hardware — i.e., The physical components of a computer system. A set of instructions that directs a computer’s hardware to perform a task is called a program, or software program.
software is also a collection of programs designed to operate, control, and expand the processing capabilities of the computer itself. System software is generally prepared by the computer manufacturers. These software products include programs written in low-level languages that communicate with the hardware at a very basic level. System software serves as an interface between the hardware and the end users.
Some examples of system software are Operating System, Compilers, Interpreter, Assemblers, and more.
Here is a list of some of the most prominent features of a system software
Less interactive
Fast in speed
Difficult to understand
Close to the system
Operating System
An operating system (OS) is a type of system software that manages the hardware and software resources of computers. Provides common services for computer programs. An operating system acts as a link between software and hardware. It controls and maintains a record of the execution of all other programs that are present on the computer, including application programs and other system software.
This are most important tasks performed by the operating system
1. Memory Management: The OS keeps track of the primary memory and allocates the memory when a process requests it.
2. Processor Management: Allocates the main memory (RAM) to a process and de-allocates it when it is no longer required.
3. File Management: Allocates and de-allocates the resources and decides who gets the resources.
4. Security: Prevents unauthorized access to programs and data by means of passwords.
5. Error-detecting Aids: Production of dumps, traces, error messages, and other debugging and error-detecting methods.
6. Scheduling: The OS schedules process through its scheduling algorithms.
Compiler: A compiler is a software that translates the code written in one language to some other language without changing the meaning of the program. The compiler is also said to make the target code efficient and optimized in terms of time and space.
A compiler performs almost all of the following operations during compilation: preprocessing, lexical analysis, parsing, semantic analysis (syntax-directed translation), conversion of input programs to an intermediate representation, code optimization and code generation. Examples of compiler may include gcc (C compiler), g ++ (C ++ Compiler), javac (Java Compiler) etc
Application
Application software products are designed to meet a particular need in a particular environment. All software applications prepared in the computer lab can fall under the category of application software.
Application software may be a single program, such as Microsoft’s Notepad for writing and editing plain text. It can also be made up of a collection of programs, often called software packages, that work together to perform a task, such as a spreadsheet.
Features of application software:
Easy to design
More interactive
Slow in speed
Generally written in high-level language
Easy to understand
Easy to manipulate and use
Bigger in size and requires large storage space
Examples of Application software
Payroll Software
Student Record Software
Inventory Management Software
Income Tax Software
Railways Reservation Software
Microsoft Office Suite Software
Microsoft Word
Microsoft Excel
Microsoft PowerPoint
Types of System Software
Here are the important tips from the system software:
Operating Systems: – The operating system software helps you efficiently use all the hardware and software components of a computer system.
Translators of programming languages: – Transforms the instructions prepared by the developers in a programming language in a form that can be interpreted or compiled and executed by a computer system.
Communication software: – Communication software allows us to transfer data and programs from one computer system to another.
Utility programs: – Utility programs are a set of programs that assist users in system maintenance tasks and in performing tasks of a routine nature.
Types of Application Software
Here, are some important types of Application Software:
Word-processing software:- It makes use of a computer for creating, modifying, viewing, storing, retrieving, and printing documents.
Spreadsheet software:- Spreadsheet software is a numeric data-analysis tool that allows you to create a computerized ledger.
Database software:- A database software is a collection of related data that is stored and retrieved according to user demand.
Graphics software:- It allows computer systems for creating, editing, drawings, graphs, etc.
Education software:- Education software allows a computer to be used as a learning and teaching tool.
Entertainment software:- This type of app allows a computer to be used as an entertainment tool.
