Understanding Software (software) Computer

Another name of the Software is software. As with any other name it, namely the software, its nature was different with the hardware or hardware, if hardware is a real component which can diliat and touched by humans, then the software or software can not be touched and seen physically, the software does not seem physical and intangible objects but can be operated.
Understanding Computer software is a collection of electronic data stored and managed by computers, electronic data stored by a computer that can be either program or instructions that will execute a command. Through software or software is a computer can run a command

Software or computer software based on its distribution can be divided into several types, namely paid software, free software or free (freeware, free software, shareware, adware).
Paid software is software that is distributed for commercial purposes, any users who wish to use or obtain the software by purchasing or paying on the party who distribute it. users who use a paid software is generally not permitted to distribute the software freely without any publisher's permission. example of this instance is paid software system microsoft windows, microsoft office, adobe photo shop, and others.
Freeware or free software is copyrighted computer software which is free to use without limit of time, is different from shareware, which requires users to pay (eg after some trial period or for additional functionality). Developers often create a free tool 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, with no additional cost. A prime example is a suite of browser and mail client and Mozilla News, also distributed under GPL (Free Software).
Free Software is more directed to the free use but not necessarily free. In fact, his name is because it is free to try open source software (Open Source) and therein lies the essence of freedom: the programs under the GPL, once obtained can be used, copied, modified and distributed freely. So free software is free does not lead to the purchase but the use and distribution. Once out of the license we can find different ways to distribute the software, including freeware, shareware or Adware. This classification affects the way in which the programs are marketed, and independent from 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 for free. Therefore, and as mentioned earlier, the Free Software does not need to be free, just as Freeware not be free.
Shareware is also free but more limited for a certain time. Shareware is a limited program is distributed both as a demonstration or evaluation version with limited features or functions or by using the specified 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 type are antivirus software, these companies usually allow the release of the product evaluation applies only to a certain number of days. After passing the maximum, the program will stop working and you need to buy the product if you want to keep using it.
We can also find free software entirely, but are included in advertising programs, 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 entry by way of banner ads or pop-ups.
