the major milestones in the evolution of today's computer. Early computing machine Abacus: The Abacus, which emerged about 5,000 years ago in Asia, can be considered as the first computer.
21 paź 2019 · The computer age was characterized by generation of computers, which signified that computer had pass through stages of evolution or development. Before we could arrive at the present day ...
• The basic elements of a digital computer are: storage, movement, processing, and control functions. • Two fundamental types of components are required: gates and memory cells.
Computers truly came into their own as great inventions in the last two decades of the 20th century. But their history stretches back more than 2500 years to the abacus: a simple calculator made from beads and wires, which is still used in some parts of the world today.
Computer is an electronic machine which performs mathematics and logical calculations. Charles Babbage is called the Father of computer. Now, in this chapter, we are trying to describe the types of computers and elaborate classification of computer. Computers can be classified in various ways depending on their
In the following subsections, we will discuss the generations of computer in terms of the technology used by them (hardware and software), computing characteristics (speed, i.e., number of instructions executed per second), physical appearance, and their applications.
• Modern silicon chips have billions of components in a 1 cm2 area. “The complexity for minimum component costs has increased at a rate of roughly a factor of two per year. Certainly over the short term this rate can be expected to continue, if not to increase.” The processor in your computer is basically billions of transistors.
