What is Software,Needs of Software,Types of Software

1)What is Software

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 large 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 software. Hardware is the physical part of the computer that we can touch that 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 these hardware such as word processing, operating system, presentation etc. Come on, who do 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 keyboard, Mouse, Printer, Internet etc. Software is also required to run them all.“Software is a Group of Programmes”

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 the High Level Language and Assembly language.

2)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 a graphic chart 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 utility 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

3)Types of Software

Divides the computer software into three parts

1)System Software

2)Application Software

3)Utility Software

1)System Software

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

System software is those that work to keep the system in control and systematic

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

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

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

Function of Operating system

1. Process Management
2. Memory Management
3. Disk and File System
4. Networking
5. Security Management
6. Device Drivers
7. Compiler

Compiler translates the source code into machine code to create the executable file. These codes are called the object code of the executable file. 

Programmer can execute this executable object file after copying it to another computer. In other words, once the program is compile, an executable file becomes independent, which does not require the compiler to be executed. Each programming language requires a compiler.

The compiler works to convert the source code into a machine code, its speed is much higher and it occupies more space in memory because it reads the entire program at once and if there is an error error massage shows

2)Application Software

Application Software There is a subclass of computer software that is 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 Computer if there is no Application Software in the Computer, then we can not do any work on Computer. Without Computer software, there is only one box without Application Software. Many programs come under the Application Software, which are the following.

1. MS word
2. MS excle
3. MS PowerPoint
4. MS access
5. MS outlook
6. MS paint

3)Utility Software

Utility Software is also known as the Service Program. It is a type of computer software designed specifically to help computerize hardware, operating system or application software.

Utility Software is software that can improve the computer by repairing the computer and helping to make it more functional.

Different Utility Software Available like

1. Disk Defragmenter
2. Scan Disk
3. Disk Cleanup
4. Anti virus
5. Disk Checker
6. System Profilers
7. Virus Scanner
8. Disk Cleaner etc.
