| Software Computer |
In the world of information technology, we often hear the Word "software". Actually what the heck the 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 explanation a bit below.
Understanding Software
Software is different with the hardware, if the hardware is a real component that can be seen and touched by human directly, then the software or the software can't be touched and seen physically, the software did not seem physically and intangible objects but can to operate.
Understanding of computer Software is a set of electronic data that is stored and managed by computer, electronic data stored on that computer can be either a program or instructions that will execute a command. Through the software or the software this is a computer able to run a command.
Types of Software
Computer software distribution based on differentiated into several kinds, i.e. paid software, free software (Freeware, free software, shareware, adware).
- Paid software
- Freeware
Free software or freeware is copyrighted computer software which is free to use without restriction of time, different from shareware which require users to pay (e.g. after a certain trial period or to gain additional functionality). The developers a free tool often makes a free tool freeware to donate to the community, but also want to maintain their rights as a developer and have control over future development. Freeware is also defined as any program that is distributed free of charge, at no 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 more leads to free use but not necessarily free. In fact, its name is because it is free to try open source software (Open Source) and that's where lies the essence of liberty: programmes under the GPL, once acquired can be used, copied, modified and distributed. So free software is not free but purchasing leads to usage and distribution. Once out of the license we can find many different ways to distribute the software, including freeware, shareware or Adware. This classification affects the way in which the program is marketed, and is independent of the software licenses where they came from.
The real difference between Free Software and Freeware. The conflict arises within the meaning of the word "free" in the language of the United Kingdom, which means both free and free. Therefore, and as previously mentioned, the Free Software need not be free, just like the Freeware should not be free.
- Shareware
Shareware is also free but more limited for a certain time. Shareware is distributed either as a limited program of demonstration or evaluation version with limited features or functions or by using a set time limit (e.g., 30 days). Thus, it gives the user the opportunity to test products before you buy and then buy the full version of the program. A very clear example of this type is the antivirus software, these companies usually allow the release of the evaluation products only applies to a specific number of days. After passing the maximum number, 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 completely, but included in the advertising program, this type of distribution 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.
That is the article an explanation of the notion of software or computer software. Hopefully the above reviews can increase you knowledge and insight in the field of computers.
