Free Essays on Four Main Parts Of A Computer

The four categories are the processor, memory, input and output devices, and storage devices. I will explain what each one of these are, in definitions. The Central Processing Unit (CPU) is what we call the processor. The computer CPU is responsible for handling all instructions and calculations that it receives from other hardware components in the computer, and software programs running on the computer. There are many different speeds of processors, but I can’t name all of them. Memory is the electronic holding place for instructions and data that your computer's microprocessor can reach quickly. Memory is often referred to as random access memory (RAM). The RAM accesses instructions and data from the more slowly accessed hard disk form of storage. There are four sections of memory, external memory, high memory area, upper memory area and conventional memory. External memory (XMS) is directly accessible memory starting at 1 MB. High memory area (HMA) is the first 64 KB of XMS, the extended memory above the first 1MB of memory. Upper memory area (UMA) is located between 640KB and 1MB. Upper Memory Block (UMB) is areas of upper memory that is remapped into RAM. Conventional memory portion of the RAM is the only portion of memory DOS. I/O (input/output), is any operation, program, or device that transfers data to or from a computer. Typical I/O devices are printers, hard disks, keyboards, and mice. A storage device is capable of storing data. The term usually refers to mass storage devices, such as disk and tape drives. So this explains the four categories of computer hardware, and their component’s and section’s....
