The most important contributions of advances in the Information
Age to society
Computers
What is computer
computer is an electronic device that stores and processes data (information). It runs on a program that contains the exact, step-by-step directions to solve a problem.
It is a single-user instrument. PCs were first known as microcomputers since they were
complete computers but built on a smaller scale than the enormous systems operated by
most businesses
Personal Computer (PC)
It is described as a PC that is not designed for portability. The assumption with a desktop
is that it will be set up in a permanent spot
Desktop Computer
These are portable computers that integrate the essentials of a desktop computer in a
battery-powered package, which are somewhat larger than a typical hardcover book.
Laptops
These are tightly integrated computers that usually have no keyboards but rely on a touch
screen for user input. PDAs are typically smaller than a paperback, lightweight, and
battery-powered
Personal Digital Assistants
It refers to a computer that has been improved to provide network services to other
computers
Server.
These are huge computer systems that can fill an entire room. They are used especially
by large firms to describe the large, expensive machines that process millions of
transactions every day
Mainframe
They involve materials that are usually integrated into cell phones, watches, and other
small objects or places. T

Internet
is a worldwide system of interconnected networks that facilitate data
transmission among innumerable computers. It was developed during the 1970s by the
Department of Defense
Sergey Brin and Larry Page
directors of a Stanford research project, built a search

Electronic mail, or emai
was a suitable way to send a message to fellow workers,
business partners, or friends. Messages could be sent and received at the convenience
of the individual.
Bioinformatics
Is the application of information technology to store, organize, and
analyze vast amounts of biological data which is available in the form of sequences and
structures of proteins–the building blocks of organisms and nucleic acids-the information
carrier
