SOFTWAREMr. Jovien G. Keliste, BSIT

WHAT IS SOFTWARE?

• is a collection of instructions that enable the user to interact with a computer, its hardware, or perform tasks. Without software, computers would be useless.

Examples and types of software

• Antivirus– AVG– McAfee

• Google Chrome• Microsoft Office

– Word– Excel– Powerpoint, etc.

• VLC• Movie Maker

How do you get software?

• Software can be purchased at a retail computer store or online and come in a box containing all the disks (floppy diskette, CD, DVD, or Blu-ray), manuals, warranty, and other documentation.

• Software can also be downloaded to a computer over the Internet. Once downloaded, setup files are run to start the installation process on your computer.

Free software• Shareware or trial software is software that gives you a

few days to try the software before you have to buy the program. After the trial time expires, you'll be asked to enter a code or to register the product before you can continue to use it.

• Freeware is completely free software that never requires payment, as long as it is not modified.

• Open source software is similar to freeware. Not only is the program given away for free, but the source code used to make the program is as well, allowing anyone to modify the program or view how it was created.

How do you use computer software?

• Once the software has been installed on to your computer hard drive, the program can be used anytime by finding the program on the computer. On a Windows computer, a program icon is added to the Start Menu or Start Screen, depending on your version of Windows.

How to maintain software

• After the software has been installed on your computer it may need to be updated to fix any found errors. Updating a program can be done using software patches. Once updates are installed any problems that may have been experienced in the program will no longer occur.

How is software created and how does it work?

• A computer programmer (or several computer programmers) write the instructions using a programming language that tell the software how to function and what to do. Once the program has been completed, it is compiled into a language that the computer can understand.

OPERATING SYSTEMMr. Jovien G. Keliste, BSIT

Operating System•  or OS is a software on the hard drive that

enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer and software programs would be useless.
