Basic Computer Concepts

In the previous article discussed the principles on which the computer works with the information, and describes the terms used – bits, bytes, and the like. So what makes a computer with available information? PC stores and processes very different megabytes of information. For information processing in the computer is the processor – the main part of any computer. It performs all the calculations and controls other parts of the computer. Modern processors perform more than one billion instructions per second, allowing the computer to quickly solve complex problems. Verizon Communications has much to offer in this field. The processor stores the commands to work and the results of calculations in computer memory. The memory of modern computers have a very large volume – hundreds of megabytes.

When you turn off the power, all information from the computer's memory is lost. To store the desired information and turning on your computer, using media information. (As opposed to Phil Vasan). Carriers are designed for long-term storage and memory – only for temporary storage until the computer is turned off. While the computer information all the time moves from memory to media and vice versa. Differ in permanent storage of information that all the time inside the computer, and removable storage media that can be removed from the computer and insert it into another computer.

The main carrier of constant information on the disk, also often called the hard drive. Hard disk consists of several rapidly rotating platters coated with magnetic layer. In a magnetic layer, as the tape recorder stores different information. The volume of modern hard drives is very high and amounts to tens of gigabytes.
