Hardware is the physical components of the computer, such as the central processing unit CPU , hard disk , monitor , keyboard and mouse. Software is the programs that run on a computer. A computer system requires both hardware and software to function. Aside from the internal components of a computer, additional hardware allows the user to communicate with the system through inputs and outputs. The table below shows some examples of input and output hardware. Operating system OS — a software that controls and coordinates the computer hardware devices and runs other software and applications on a computer.
It is the main part of system software and a computer will not function without it. Device driver — a software program that is designed to control a particular hardware device that is attached to a computer. Utility software — a type of system software that helps set up, analyze, configure, strengthen, maintain a computer and performs a very specific task e. Skip to content Unit 7. Evolution of computers.
They perform transferring of data to hard disk, It performs text or images or graphics to be seen on display devices,. There are various other system software which is developed for specific tasks, such as device drivers are installed in PC for better functionality of that device, for example:: Device drivers of display cards and sound cards are used in viewing better resolutions on the computer screen and hearing sound from soundcards.
Programming tools, utility software, compiler, the interpreter is also considered to be system software. System software can be operating system and language processors. Assembly language and High-level languages to machine language which is a language that is understood by computers. These are those programs that translate codes that are written in high-level or Assembly language into Machine language or that language that is easily understood by the computer.

Such as mouse, sound cards, and keyboards. These utility programs help the user to better communicate and interact with software and hardware. It presents the user with a GUI stands for Graphical User Interface where the user can directly communicate or interact with hardware and software used in computer systems. Application Software is a program that is designed and developed for specific purposes and for a special task that is directly used by the users.
In other words, it can be described as an interface between user and system software, which helps the user to perform a given specific task. They are designed and developed as well as customized as per the requirements of the clients. They are developed to perform a special and specific task as the user needs. The developer or the programmer has the privileges to change or update or add or delete the source code of the software any time when found necessary.
