What is software and its type or how it made? [2020]



That is the part of the software computer that we can only see and work on it, the software is created to simplify the task of computers, nowadays software is built according to the work, as Work Software.

Software is designed by software programmers keeping in mind the needs of the users in big companies, some of which are available in free and charge for some. For example, if you have to work related to the photo, then use the media player for photoshop or any video to see it.

Computers are a set of different programs through which specific tasks can be done. The computer has two parts, the first is called the hardware, while the other is software. Hardware is the physical part of the computer that we can touch, which performs a certain task for which they have been created, such as Keyboard, Mouse, Monitor, CPU, Printer, Projector, etc.

In contrast, there is a set of software programs that determine the functions of this hardware such as word processing, Operating System, Presentation, etc. Come on, who does the interface with the hardware.

If the comparison of the hardware goes from the computer's body then the software is compared to the computer's mind. Just as the human body is useless without the brain, there is no existence of a computer without software. For example, we use a keyboard, Mouse, Printer, Internet, etc. Software is also required to run them all.

"Software is a Group of Programs"

After Computer On, Software is loaded first in RAM, and Execute is done in Central Processing Unit. It is made in Machine Language, which is special for a different processor. It is also written in High-Level Language and Assembly Language.

Needs of Software

As we know, there is a group of computers, hardware, and software, if the software is removed from it, then the computer will remain like a box. This box can not work until that time in which Operating System Software is not loaded. This means that Operating System Software is required to do anything in Computer.

We also require some software other than operating system software. For example, if you want to type a letter or create graphics charts or create a presentation or manage your office personal data then you need again several different software for different purposes Which is called Application Software.

In addition, if your computer gets infected with the virus, then you will need a software called Utility. In short, if you have a computer system and you want to work smoothly, you will need software from time to time.

The software may need the following reasons:
  • To turn on Computer
  • To type the letter
  • To create a chart
  • To Create Presentation
  • To manage data
  • To use internet


History of Software

An outline (algorithm) for the first part of the software was written by Anda Lovelace in the 19th century, which was for analytical engine.

However, neither the analytical engine nor any software has ever been created for it.

The first principle about the software - before the creation of computers, as we know today - Alan Turing proposed in the 1953 essay with an application for the consolidated numbers Entscheidungs problem (Decision Problem).

Since then, the field of computer science and software engineering was created. Computer science is more theoretical (Turing Computer Science essay is an example), where software engineering focuses on more practical business.

However, before 1946, as software, as we now understand, store programs from the memory of digital computers - were not yet available. Earlier electronic computing devices had to rewire to do "reprogram" instead.


Types of Software





The computer software divides into three parts. System Software, Application Software, and Utility Software.

1.System Software


The system software is a software that manages and controls hardware so that application software can complete its task. This is a necessary part of the computer system, the operating system is a clear example.


"System Software is the one that works to keep the system in control and systematic"

If the system software is stored in non-volatile storage such as Integrated Circuit (IC), then it is usually given the name of the firmware, in short, a system is a group of software programs. There are several types of System Software like-

  • Operating System Software
  • Compiler
  • Interpreter
  • Assembler
  • Linker
  • Loader
  • Debugger etc.

 

Operating System Software

Operating System is a System Software, which is loaded after the computer is turned on. That is, this is a necessary program for a computer to boot. In addition to booting this computer, it is necessary for other application software and utility software.

The function of the Operating system


  • Process Management
  • Memory Management
  • Disk and File System
  • Networking
  • Security Management
  • Device Drivers


Compiler

A compiler translates the source code into machine code to create the executable file. These codes are called the object code of the executable file. The programmer can execute this executable object file after copying it to another computer.

In other words, once the program is compiled, an executable file becomes independent, which does not require the compiler to be executed. Every programming language needs Compiler.

The compiler works to convert the source code into machine code, its speed is greater and it occupies more space in memory because it reads the entire program at once and if there are an error message shows. |

Interpreter

An interpreter is a program that works in converting a program written in High-Level language into Machine Language. An interpreter translates a single instruction to machine language alternately. All instruction in this high-level language program together does not translate into machine language.

  The interpreter occupies less space in memory because it checks every line of the program alternately and if any error occurs in a line, then it immediately shows Error Massage, and until the mistake is corrected This does not let go further.


 Assembler

Assembler is a program that translates assembly language into machine language. In addition, it translates the high-level language into Machine language, it changes the mnemonic code like ADD, NOV, SUB, etc. into the Binary Code.


2.Application Software

Application Software is a subclass of computer software used to do the desired work by the user.

"Application Software is the Software that works to add User and Computer."

Application Software is very useful for computers if there is no Application Software on the computer, then we can not do any work on a computer. Without Application Software, computers are just a box. Many programs come under the Application Software, which is the following.

  • Ms word
  • MS Excel
  • MS PowerPoint
  • MS Access
  • MS Outlook
  • MS Paint


3.Utility Software

Utility software is also known as a service program. It is a type of computer software designed specifically to help in the installation of computer hardware, operating system, or application software.

"Utility Software is software that increases the efficiency of a computer by repairing the computer and helping to make it more functional."

 Different types of utility software are available such as-

  • Disk Defragmenter
  • Scan Disk
  • Disk Cleanup
  • Antivirus
  • Disk Checker
  • System Profilers
  • Virus Scanner
  • Disk Cleaner etc.


How software is made


Creating computer software is a bit of a difficult task. Because to perform this task you must have good knowledge of the required programming languages ​​and a lot of patience. Only then can you become a professional software developer.

Dozens of programming languages ​​have been developed to create software. By which you can create software for different needs.

You can not become experts in all languages. Not impossible. You can learn. But for beginners, you can do Java, C, C ++ by learning basic languages. And try your hand at Computer Coding.

Types of Software License


Types of software licenses:

The license of the software empowers the user to use the software in a licensed environment.
A software license is legally enforceable which specifies the terms of use for an application and defines the rights of software manufacturer and end-user.
Here is a list of the default license types filtered by the manufacturer:

1) Freeware:



As its name suggests, freeware is a software that is free to download and use.
Freeware's distribution is not registered by any copyright. You can download it and use it without paying. Freeware expires after Limited Time Limited.


2) Shareware:



Shareware is copyright software that is free to download but it is used in some way.
Shareware can expire after a limited period, after which you may have to pay again to use the software.
In other cases, there can be no time limit, but you can not access all the features of the software until you give any payment.

3) Limited License:



Limited license software is for use only for non-commercial purposes. To use this software, customers are restricted to the number of computers.

4) Unlimited Site License:



There is no restriction on this license type in how many computers you are installing this software on.
Such software is popular in education institutes so that they can provide it to their faculty and staff.
But such unlimited site licenses allow only one physical location, such as a college campus or the use of software in the office.

5) Enterprise Site License:



An enterprise license is like an unlimited site license, but it is not limited to only one physical location.
A company that has offices in different locations allows the software to be installed in all its offices.
Customers can be limited to the number of such computers on which this software can be used, such as 50 or 100 computers.

6) Volume Purchase Agreement:



Volume Purchase Agreement makes it possible for the organization to buy a large number of copyright software at a lower cost.
Customers can install this software on multiple computers, usually from a DVD or CD, and usually, they have the same product keys for which they are activated.

7) Single License:



This type of license allows you to install software on only one computer. If you have to install software on additional computers, you will have to buy a separate license for each computer.
When you buy a branded laptop or computer and with that license of Microsoft Windows, it is a single license (OEM).

8) Client Access License (CAL):



Users are given access to the server in the Client Access License (CAL) license type.
The more client access licenses you can take, the more the client can connect to the server.

9) Node-Locked:



These licenses are for specific workstations of typical configurations and they run on them.

10) Open Source Software:



Open-source software comes with free software licenses, which give users the right to modifiers and redistributable software.

Enterprise Software

Enterprise software, also known as Enterprise Application Software (EAS), is computer software used to meet the requirements of organizations rather than users.

Today, there are many instances of this enterprise application being used-

1) Artificial intelligence:


The development of artificial intelligence (AI) was a difficult possibility some years ago. But it is, in fact, rapidly developing technology that offers opportunities for businesses that promote their employees and change the users' experience.

It's getting so popular that it is estimated that by 2020 AI will be in every software product.


2) Machine learning:


Machine learning is one of the most modern software technologies that entrepreneurs are embracing. It comes from the world of automation and helps the organization to increase internal operations and provide new customer experiences.


 3) Customer Relationship Management (CRM):


CRM software is used in enterprise engagement with customers in both queries related to sales and service.

It applies to Business-To-Customer (B2C) and Business-To-Business (B2B) interactions.

It tracks the information, customers, clients, sales, leads, and more that information.

This helps in providing relocation data to the organization so that sales teams help in identifying the service or product that customers want.

With this, they can provide better services to the customers, help the Sales Team help cross-sell and up-sell, understands the needs of customers in an affirmative and better way.


4) Enterprise Resource Planning (ERP):


ERP is a Business Process Management (BPM) software, which allows an organization to manage a business and integrate applications related to technology, service, and human resources.

ERP software handles important backend processes; Purchase History, Billing and Shipping Details, Accounting Informations, Financial Data, and Supply Chain Management Details. It integrates all operations from the same database, application and user interface into the organization.


5) Human Capital Management (HCM):


Human Resource Management System (HRMS) and the HR system are used to integrate the Employee Records and Talent Management System to display Human Resources.

It is important for this employee to keep track of data, and it is common for most companies to have a major human capital management system that is currently centered around areas like payroll, compliance, and admin.


6) Business Intelligence Software:


The primary goal of Business intelligence software is to remove critical data from the RAW data of the organization, to help the business make the fastest and most accurate decision-making.

It is an application designed for retrieving, analyzing, transforming, and reporting data for business intelligencers.


7) Enterprise Information Management (EIM):


There is a special field within EIM Information Technology. It specializes in finding a solution to the best use of information within the organization.
