A computer is a machine that can be programmed to carry out a sequence of arithmetic or logical operations. Computers are used as control systems for a wide variety of industrial and consumer devices.
Computers can be classified into a number of different types, based on size, power requirements, and general-purpose or special-purpose functionality. There are also different types of computer architecture, which define the internal makeup of a computer.
Most computers are controlled by a central processing unit (CPU), which is the main component that carries out the instructions of a computer program. Other important components include the system memory, or random access memory (RAM), which stores the program instructions and data currently being used by the CPU, and the secondary storage, which provides long-term storage for data.
The most common problem with a computer is that it will not turn on. If your computer will not turn on, the first thing you should do is check the power cord to make sure it is plugged in properly. If the power cord is plugged in and the computer still will not turn on, the next step is to check the power supply.
If the power supply is not the problem, the next step is to test the motherboard. To test the motherboard, you will need to use a diagnostic card. If the motherboard is not the problem, the next step is to test the RAM. To test the RAM, you will need to use a diagnostic program.
