Number System

 The number system is something we use every day to complete our tasks and routine activities. For this, we have a system in place with unique symbols and specific values. This system becomes what we call a number system helping us calculate everything.

The basic features of a number system are – unique symbols, consistency, comparable value results and are easy to reproduce. The Decimal system remains the most basic system used by humans with a base power of 10 but the same things can’t go for machines as well. 

There are four number systems that a computer supports. They are – 

  1. Binary
  2. Octal
  3. Decimal
  4. Hexadecimal

Introduction to Computer

Image
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 the hallmark of the third generation of computers.  Transistors were miniaturiz
