Software is a term used to describe a set of instructions and data that a computer program needs to run. It is similar to hardware in that it is a component of a computer.
There are many different types of software, including applications, system software and firmware. Applications are designed to perform specific tasks and are usually larger packages.
System software is a type of software that is preinstalled on a computer. This includes the operating system, which is the first thing that is loaded into the system memory when the machine turns on. The operating system acts as an interface between the application software and the computer hardware.
Firmware is a set of instructions that are permanently engraved into the hardware. This allows the device to interface with other computers and perform basic input/output activities.
Simulation software is a good example of a software product. It is used in engineering, robotics, and weather forecasting. MATLAB is a good example of a simulation software product.
Freeware is a form of software that is available for download on most operating systems. Some of the most popular freeware products are browsers, games, and communication apps. Others are limited to personal use only, such as Adobe Reader.
Shareware is a type of application software. It is free, but it has some restrictions on the function of the application. In some cases, it requires a license key to activate.
Graphics software is used to manipulate visual data. Examples of graphics software include Unity 3d, PaintShop, and Adobe Photoshop.
