At first, as a computer novice, one must be acquainted with the machine, that is called the computer. A computer is basically an electronic machine that needs an electric power supply to function. A computer system is used basically to process all the data given by us. It processes data or information from one end, stores it in memory, and finalize the processing process on the other end – until the data is completely outputed. Basically, a computer works by storing data that has to be processed, receiving information that is processed and sending information that is received back to another source.
Basically, computers are divided into two major categories desktop and mainframe computers. Desktop computers are the most common type of computer found in homes and small offices. Mainframes are the biggest and most powerful type of computer system. The central processing unit or CPU, is the brain of all computers.
An instruction set is a series of instructions that a CPU follows in executing its tasks. Instructions are generally stored in RAM or main memory. A CPU can execute instructions during operation while the rest of the computer stays idle unless it is prompted to do so. When a task is performed, the operating system schedules the time of execution of the various tasks that are performing on the CPU.
There are many types of ports on a computer. These ports are referred to sockets that allow input and output of electronic signals. The most common ports are USB, motherboards, scanners, printers, USB drives and audio and video ports. Most people have one or more ports but you will find that some computers have as many as sixteen ports all of which can be used for different purposes.
One thing that separates computers from other machines is its storage. Computers stores programs and data in RAM, main memory, hard drive or some other storage medium. Storage is very important because without it a computer cannot function. In addition, a computer has its own architecture complete with power supply units, processors, memory modules and communication ports. All of these components work together to provide the basic operating functions of the machine.
A computer consists of hardware and software components. A computer’s architecture usually consists of four main components: an input device, output device, processing device and memory. These parts are connected in a particular order in order to provide the desired results. Each component performs a specific job and is assigned a specific task to accomplish.
One of the most important parts of a computer is its microprocessor. The main purpose of the microprocessor is to control and coordinate all of the main processing units. The different main processing units of a computer are the registers, microcoded instructions, hardware instructions and microprocessor tasks. The register consists of instructions that tell the CPU to start an instruction; an instruction specifies what data to be collected at a later time; and a microcoded instruction tells the CPU what actions to take. All of these combine to provide the complex output of the computer.
The registers of a PC are the storage for instructions and data. The microcoded instructions tell the computer what actions to take. The output of the computer is the results of all of the actions taken. In order to understand how a computer works it is helpful to know what each part of the computer is for and how it works in conjunction with each other.
The parts of a desktop computer that are directly seen are the monitor, keyboard and the mouse. These three components control and receive data from input devices such as joysticks, pointing devices, and earbuds. The monitor is what you see when your computer is connected to a monitor. The keyboard is what your computer uses to send information to the various input devices and is what you see on your screen. And finally, the mouse allows you to move the computer cursor, although this last component is not actually part of a computer.
Computers perform many different tasks. The three most important components to a desktop computer are memory, hard drive space and speed. All of these components have an effect on the speed and performance of your computer. Obviously, if you do not have enough memory or if your hard drive is too small you will not be able to store a lot of information and will not be able to browse the Internet quickly.
If your computer has problems, one of the first things to check are all of the components. A slow computer often has a problem with the main input device such as the mouse or keyboard. Another common problem for new computers is the slow performance of the random access memory or RAM. Another potential source of error is the floppy disk drive. Other potential sources of error include the power supply or the floppy disk drive itself.
