Decimal Number System

 The decimal number system, also known as the base-10 number system, is the most commonly used number system in everyday life. It uses ten digits - 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 - to represent all numbers.

In the decimal system, each digit has a place value that is a power of 10. The rightmost digit represents the units place, the next digit to the left represents the tens place, the next represents the hundreds place, and so on.

For example, the decimal number "547" represents:

510^2 + 410^1 + 7*10^0 = 500 + 40 + 7 = 547

The decimal system is used in everyday life for counting, measuring, and money transactions. It is also used in computer programming and electronics as a way to represent and process numbers.

Computers are electronic devices that are designed to process, store, and retrieve data. They are used for a wide variety of purposes, from personal computing to complex scientific simulations and industrial automation. A computer consists of various hardware components, including a central processing unit (CPU), memory, storage devices, input/output (I/O) devices such as keyboards, mice, and displays, and various other peripherals. Computers communicate with each other over networks, which are interconnected groups of computers that share resources and information. The internet is a global network that connects millions of computers around the world and enables communication and information sharing on an unprecedented scale. The field of computer science is concerned with the study of computers and computational systems, including their design, development, and application. It encompasses many subfields, including artificial intelligence, computer graphics, databases, programming lang...

Computer Generation

 There are five generations of computer:  First generation– 1946 - 1958  Second generation– 1959 - 1964  Third generation– 1965 - 1970  Fourth generation– 1971 - today  Fifth generation– Today to future The First Generation   The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.  They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. The Second Generation   Transistors replaced vacuum tubes and ushered in the second generation of computers.  One transistor replaced the equivalent of 40 vacuum tubes.    Allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable.  Still generated a great deal of heat that can damage the computer. The Third Generation  The development of the integrated circuit was ...
