How Does a Computer Encode and Process Information?
Binary System of Encoding Data is input into a computer. The computer encodes the information using binary code (see Resources). The information received by the computer is encoded using 1s and 0s. A 1 means “true,” and a 0 means “false.” Computers think in base 2, which is the use of two digits to form a numbering system. Once the information is encoded, it is moved to the central processing unit (CPU). Central Processing Unit The CPU is a computer’s brain, where all of the information is processed by the computer. The CPU of a typical desktop or laptop computer is housed on a chip called a processor or microprocessor. CPUs come in varying speeds. Faster processors allow a computer to rapidly perform logical calculations and swiftly execute instructions. Slower processors perform the same calculations but at a slower rate. The CPU consists of two components: the arithmetic logic unit (ALU), where logical and arithmetic functions occur; and the control unit (CU), which decodes informat
