Tips 86

* A computer system can only interpret either "1" or "0". The enormous speed of processing power enables the computer system to translate these numbers alongside with formulas or algorithm and to produce results from the given circumstances. These results are to be decoded into human language (E.g.: English sentence or numbers).

The faster the speed, the better the performance is. The speed is usually measured in "hertz" (E.g. Kilohertz, Megahertz, Gigahertz). This technology has been used in data transmission and also satellite signaling. The speed of transmission is fast and produces excellent picture quality.

A bit about computer basics.

A bit (short for binary digit) is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1. Although computers usually provide instructions that can test and manipulate bits, they generally are designed to store data and execute instructions in bit multiples called bytes. In most computer systems, there are eight bits in a byte. The value of a bit is usually stored as either above or below a designated level of electrical charge in a single capacitor within a memory device.

Half a byte (four bits) is called a nibble. In some systems, the term octet is used for an eight-bit unit instead of byte. In many systems, four eight-bit bytes or octets form a 32-bit word. In such systems, instruction lengths are sometimes expressed as full-word (32 bits in length) or half-word (16 bits in length).
