Computers are a nice electronic to have at home, school, or work. They have quickly become a necessity in our generation in order to do all the things we do in life now. We have computers everywhere at our desk's, pockets, office everywhere in which they help us do many things-from helping us do our taxes to setting the right temperature in a room to just having entertainment. This report will help to understand the three main components of a computer: hardware, software, and operating systems.
The motherboard is the main component inside the case. It is a large board with an integrated circuitry that connects the parts of the computer which includes the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots. The CPU or "The central processing unit" performs most of the calculations which help a computer to work, and is sometimes referred to as the "brain" of the computer. It is usually cooled by a fan. Now the RAM or "Random Access Memory" stores resident part of the current running OS (OS core and so on) and all running processes (applications parts, using CPU or input/output (I/O) channels or waiting for CPU or I/O channels).
Computer software is a collection of computer programs and data that help instructions by telling a computer what to do and how to do it. In other words software is a set of programs and procedures. System Software performs the function of the program it implements, either by providing instructions for the computer hardware or by serving as an input to another piece of software. In difference to hardware, software is can't be touched physically. A device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device and the Operating system (OS) is software, consisting of programs and data, that runs on computers and manages computer hardware resources and provides common services for efficient execution of various application software. The server is a computer program running as a service, to serve the needs or requests of other programs which may or may not be running on the same computer.
The Program Software has A compiler which is a computer program that transforms source code written in a programming language into another computer language. The most common reason for wanting to transform source code is to create an executable program. A debugger is a computer program that is used to test and debug other programs (the "target" program) or to get rid of. In computer science, an interpreter normally means a computer program that executes, performs, instructions written in a programming language. An interpreter may be a program that either
executes the source code directly
translates source code into some efficient intermediate representation (code) and immediately executes this
explicitly executes stored precompiled code made by a compiler which is part of the interpreter system

OPERATING SYSTEMS
An operating system (OS) is software, consisting of programs and data, and that runs on computers and manages the computer hardware resources and provides common services for efficient execution of various application software. DOS, short for "Disk Operating System", is an acronym for several closely related operating systems that dominated the IBM PC compatible market between 1981 and 1995, or until about 2000 if one includes the partially DOS-based Microsoft Windows versions 95,98, and Millennium Edition.

Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Microsoft first introduced an operating environment named Windows on November 20, 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs).

The Macintosh or Mac, is a series of several lines of personal computers designed, developed, and marketed by Apple Inc.

Conclusion
Computers come in all shapes and sizes-from a digital watch to the sprinkler system that waters the grass. All computers have hardware (the physical side), software (the program side), and an operating system (the software that controls the hardware). There are many examples of each of these items all around us. Hopefully, you will notice more examples now that you know more about them.
