Understanding Software or software is one important component in the computer. Simply put, the notion of software is data that has been programmed and stored digitally but not physically visible but is inside a computer. This software can be a program to run commands through this software so the computer can operate.
Software also has an important role on the computer, because with the software hardware can be driven or controlled properly. This software is made using a programming language that was created and written by a programmer which is then compiled by an application called a compiler to be a code that can be recognized by the hardware.
Types of software on computers
1. Freeware
Ie a free software that can be used without any time limit, in general this freeware is donated to several communities, but freeware also has the rights of developers and controllers in the development of subsequent applications. But if the application developer stops developing the product to another freeware or announces that the freeware can be developed together, the freeware will provide the source code.
2. Shareware
It is a software that has been tested for free but with limited features such as availability, functionality, and convenience which unfortunately cannot be utilized optimally. This trial software aims to introduce the software as a marketing strategy in developing the shareware application itself. Shareware is often called trialware.
3. Firmware
Namely a software that is located in the ROM (Read Only Memory). This firmware cannot be changed even though it has no electricity, and the storage can not be changed in ROM but can still be modified depending on the type of ROM such as EEPROM or flashROM. All that can still be changed according to their needs.
4. Commercial software

Anyone who uses this software freely can commercialize and take advantage of the distribution and modification of the source code. In addition, this software can also be distributed for free.
6. Open source software
It is software whose source code can be learned, modified, improved, and also distributed. Because the nature of this software is open, so the development carried out by an open community or group can develop software with open source.
7. Malware
Malware is one software that was created to damage a system on a computer and a computer network but without the permission of the owner. Another word of this malware is a computer virus, the types of devices contained in this computer virus are Trojan horses, advertising devices, computer worms, rootkits, and other malicious software.
Software Functions
Software Functions in General
1. Providing basic functions for computer needs which are further divided into operating systems or only support systems.
2. Arrange a variety of hardware so that it can work together.
3. As a link between other software and hardware.
4. As another software translator in the instructions into machine language so that it can be accepted by the hardware.
5. As a program identifier.
