The three basic subsystems of a computer system are the central processing unit (CPU), the random access memory (RAM) and the storage. Each subsystem can be broken down into smaller systems, but these are the three major subsystems of any computer.Continue Reading
The CPU is the component that processes instructions. It receives input from the computer's user, operates applications and the operating system and processes data to provide output.
RAM provides the operating memory for the computer. The more processes a computer needs to run at a single time, the more RAM it needs. Operating processes from RAM is much faster than running them from a disk or hard drive.
A computer's storage permits it to permanently store files and data. The hard drive is a common storage device that varies in capacity.Learn more about Computers & Hardware
RAM, or random access memory, is the storage space for data used by the operating system and other programs while the computer is in use. RAM is volatile, meaning that it exists only while the computer is powered on and changes along with the system's immediate requirements.Full Answer >
CPU stands for central processing unit, the part of a computer's hardware that performs the instructions of programs and controls the operations of the system. Simply put, it is the brain of the computer.Full Answer >
Microprocessors serve as the central processing unit in a computer system and are involved in the actual execution of machine instructions. Instructions stored in the memory of a computer tell the microprocessors what to do and how to do it. A component of the microprocessor called the arithmetic/logic unit performs arithmetic operations such as addition, subtraction, multiplication and division. Microprocessors also transfer data from one memory location to another.Full Answer >
The important components of a computer are the CPU, memory, graphics adapter, storage system and power supply. The motherboard connects these components together inside the case. Outside the case, the input system includes a keyboard and mouse, and the output display is usually a monitor.Full Answer >
