Definition of Computer Software. In the information technology world we often hear the word software. Actually what is software? Some say that without the software, then a computer can not be used or operated. To know the definition or understanding of the software please refer to the little explanation below.
Definition Software
Another name of the Software is software. Because also referred to as software, then its nature is different to the hardware or hardware, if the hardware is a component that is real and can be seen and touched by humans, then the software or the software can not be touched and seen physically, the software does not appear to be physical and intangible objects but can be to operate.
Definition of Computer Software is a set of electronic data is stored and managed by computer, electronic data stored by the computer in the form of programs or instructions that can run a command. Through this software the computer can run the command
Types of Software
Computer software can be divided into several types, namely paid software, free software (freeware, free software, shareware, adware).
Paid software
Paid software is software distributed for commercial purposes, any users who want to use or obtain the software by way of purchase or pay for the parties to distribute it. users who use paid software is not permitted to disseminate the paid software without permission from the publisher. an example of this example is a paid software system Microsoft Windows, Microsoft Office, Adobe Photo Shop, and others.
Freeware
Freeware is copyrighted computer software which is free to use without any time limit, different from shareware which requires users to pay (eg after a certain trial period or to acquire additional functions). The free software developers often make the free tool freeware to be donated to the community, but also still want to retain their rights as a developer and have control over future development. Freeware is also defined as any program that is distributed free of charge, without any additional cost. A prime example is a suite of browser and mail client and Mozilla News, also distributed under the GPL (Free Software).
Free Software
Free Software is more directed to the free use but not necessarily free. In fact, its name is because it is free to try open source software (Open Source) and therein lies the essence of freedom: the programs under GPL, once obtained can be used, copied, modified and distributed freely. So free software does not lead to a free purchases but the use and distribution. Once out of the license we can find different ways to distribute software, including freeware, shareware or adware. This classification affect the way in which programs are marketed, and independent of software licenses to which they belong.
The real difference between Free Software and Freeware. Conflicts arise within the meaning of the word free in English, which means both free and free of charge. Therefore, and as mentioned before, the Free Software does not need to be free, just as Freeware should not be free.
Shareware
Shareware is also free but more restricted to a certain time. Shareware
is a limited program distributed both as a demonstration or evaluation
version with limited features or functions or by using a set time limit
(eg 30 days). Thus, giving users the opportunity to test the product before buying and then buy the full version of the program. A
very clear example of this is the type of antivirus software, these
companies usually allow the release of a product evaluation that applies
only to a certain number of days. After passing through the maximum, the program will stop working and you need to buy a product if you want to keep using it.
We can also find free software entirely, but included in the advertising program, the distribution of this type is called Adware. A clear example is the Messenger program from Microsoft that allows the use of free software in exchange for admission by way of banner ads or pop-ups.
