How Computers Work

THE BASIC PARTS OF COMPUTER The basic parts of a computer are the central processing unit (CPU), memory, a keyboard or other input device, and a screen or other output device.

How does a computer add or subtract, and how can its memory remember the answers it computes? A computer does not have a human brain inside but acts in many ways as though it does have a real one. However, while we understand human language, the computer can understand machine language. When a person types on the computer's keyboard, the human brain identifies the letters, numbers, and characters combined to create words and sentences. But the computer does not recognize letters as letters of the alphabet; it sees the letters as a series of 0's and 1's called the binary language .

What is Binary Language? Binary is a base-2 numeral system that only has two digits: 0 and 1. In computers, it is the underlying language for representing and processing data. Each digit in a binary integer is called a bit, and its position corresponds to a power of two. This technique is essential in digital systems like computers, where electrical impulses may be easily read as either on (1) or off (0). By organizing these binary digits, electronic devices may efficiently transfer and analyze complex data, commands, and codes

Computer Number Systems Humans use the decimal number system to count, measure, and compute. The decimal number system has ten digits, such as 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. A computer, on the other hand, can only understand two digits-a 0 and a 1. These two numbers play an important role in the way computers communicate with one another. This type of number system is called the binary number system, with the prefix bi, which means 2. There are other types of number systems, such as the octal number system (from the prefix octa, meaning it uses 8 digits) and the hexadecimal number system ( hexa means 6; deci means 10, meaning it uses 16 digits to represent its values). However, these special number systems are merely a way to bridge the computer's binary language to a somewhat understandable human (decimal) language since computer data can be complicated.
