What does Software mean ?
Software, in its most general sense, is a set of instructions or programs instructing a computer to do specific tasks.
Software is a generic term used to describe computer programs.
Scripts, applications, programs and a set of instructions are the terms often used to describe software.
The word software was first used by John Tukey in 1958.
The theory of software was first proposed by Alan Turing in 1935.
>> Software is often divided into three categories:
System software serves as a base for application software.
System software includes device drivers, operating systems (OSs), compilers, disk formatters, text editors and utilities helping the computer to operate more efficiently.
It is also responsible for managing hardware components and providing basic non-task specific functions.
The system software is usually written in C programming language.
Programming software is a set of tools to aid the developers to write programs.
The various tools available are compilers, linkers, debuggers, interpreters and text editors.
Application software is intended to perform certain tasks.
Examples of application software include office suites, gaming applications, database systems and educational software.
Application software can be a single program or a collection of small programs.

Top Programs That Can Make Your Computer Run Faster
Thereâs plenty of software out there to speed up your computer.
Letâs take a look at some programs that can bring your system back to its former glory.
>> MSConfig / Task Manager
In theory, having lots of software on your computer probably isnât causing a slowdown by itself.
When you have two dozen programs all trying to run when you first start the system, though, thatâs where problems occur.
The built-in utility MSConfig can help you cut down on the amount of programs that run automatically.
To access it in Windows 7, type msconfig into the Start Menu to open the System Configuration window.
Click on the Startup tab to view everything that starts running when you boot into Windows.
If youâre on Windows 8 or 10, this tab will instead refer you to the Startup tab of the revamped Task Manager.
Once in the Startup menu, you can start unchecking boxes (on Windows 7) or right-clicking and choosing Disable (on Windows 8 or 10) to prevent items from running at boot.
Be sure that you know what a program does before disabling it.
You donât want to stop your antivirus or backup software from running at startup, since you need those active all the time.
>> Disk Cleanup / CCleaner
You might already know, but a lot of files on your computer arenât necessary for any program.
From leftover Windows Update files to temporary data used by your web browser, you could have several gigabytes of junk just sitting around.
If this is filling up your hard drive, it could affect performance.
Your best two options for cleaning up temporary data are the built-in Disk Cleanup tool and CCleaner.
>> Revo Uninstaller
While it helps to prevent non-critical software from running at startup, itâs even better to uninstall programs you donât use.
This will free up space and save resources.
You can always use the Programs and Features menu in Windows to uninstall software, but going a step further with Revo Uninstaller is a good idea.
Revo allows you to obliterate every trace of a program on your system.
After running the built-in uninstaller, it scans for extra pieces.
However, donât fret about the items that Revo finds in the Registry during the uninstall process.
Cleaning the Registry is useless and youâre better off leaving it alone to avoid damage.
Paired up with our other tips, Revo is one part of a great offense against troublesome software that might be slowing down your system.
>> Disk Defragmenter
While solid state drives (SSDs) are becoming more popular, traditional hard disk drives (HDDs) are still widely used.
If you use an HDD, regular defragmentation can help keep the drive performing at its best.
The built-in Disk Defragmenter / Optimize Drives tool in Windows is all most people need for defragmentation.
Simply click Analyze to find out how fragmented the drive is, then Defragment / Optimize to begin the process.
Modern versions of Windows perform this process on a schedule automatically, so you wonât need to manually run this utility.
>> Consider Lighter Alternatives
In some cases, you can replace slow software with a speedier alternative to keep things running quickly.
One example is Google Chrome, which is notorious for hogging RAM and running slowly on low-end systems.
If you can break out of Chromeâs trap, speed up your browsing by using Firefox or giving Opera a try.
Other software you use might be slowing down your experience.
If you regularly work with massive PDFs, try a lighter alternative to Adobe Reader.
Donât use the, bloated ÂµTorrent; replace it with a BitTorrent client thatâs light as a feather.
