You’ve probably known about puters your whole life. But puters have not really been around for very long. Computers started to bee popular with big panies in the 1960s. Computers didn’t bee widespread in homes and schools until the 1980s.
HOW DO PEOPLE USE COMPUTERS?
People use puters in many ways. Stores use puters to keep track of products and check you out at the cash register. Banks use puters to send money all over the world.
Computers help teachers keep track of lessons and grades. They help students do research and learn. Computers let you hook up to neorks (many puters hooked together). They let you hook up to a worldwide neork called the Inter.
Scientists use puters to solve research problems. Engineers use puters to make cars, trucks, and airplanes. Architects use puters to design houses and other buildings. The police use puters to track down criminals. The military uses puters to make and read coded messages.
Computers are not just desktops and laptops. Computers are everywhere around your home. There are tiny puters inside microwave ovens, television sets, and videocassette recorders (VCRs) or digital video disc (DVD) players. There are even tiny puters in cars to help them run better.
HARDWARE AND SOFTWARE
Computers need hardware and sofare in order to work. Your desktop or laptop and all the parts inside are called hardware. The central processing unit (CPU) makes the puter work. The keyboard, mouse, printer, and monitor are also pieces of puter hardware.
Memory chips are hardware that stores information and instructions. Information also gets stored on the hard disk drive.
The programs that run the puter are called sofare. The puter operating system is sofare that tells the puter how to run. Applications or programs are sofare that do certain tasks. Word-processing programs, for example, let you write school reports and letters.
HOW CAN COMPUTERS DO SO MUCH?
One reason that puters can do so much is that they have a special language that tells them what to do. Computer language has only o letters: zeros and ones. Computers can read these ones and zeros extremely quickly.
Each zero or one is called a bit. Eight zeros and ones together are called a byte. Bits and bytes get stored in puter memory chips. Every year, puter engineers make chips that can hold more bytes. The chips can hold more information. Programmers can write applications that can do more things.
WHO INVENTED THE COMPUTER?
Many inventions have contributed to the development of modern puters. French mathematician Blaise Pascal and other inventors in the 1600s began making machines that could add and subtract numbers. Wheels, levers, and other moving parts made these machines work. In the 1800s, British mathematicians Charles Babbage and Augusta Ada Byron, countess of Lovelace, worked on plans for machines that could store information on cards with holes punched in them.
American inventor Herman Hollerith made a machine that automatically totaled population figures for the 1890 United States census. His pany joined with other panies to bee International Business Machines (IBM) in 1924. Other inventors built better puters. But none of these early puters were digital—that is, none used the digits zero and one.
The first digital puter, called ENIAC, was built in the 1940s. It was huge. It was as big as a house. It had more than 18,000 glass tubes inside and weighed more than five elephants.
The first puter used by business was called UNIVAC. Big puters like ENIAC and UNIVAC were called mainframes. The desktop or laptop puter that you use today is much more powerful than those big machines.
In the 1940s, scientists at Bell Telephone Laboratories invented a tiny electric switch called the transistor. In the 1960s, scientists and engineers invented integrated circuits or puter chips. Computer chips cram millions of transistors into a space the size of your little fingernail. Computer chips allowed puters to be *** aller.
Personal puters (PCs) were invented in the 1970s. Most PCs are meant to be used by only one person at a time. They are *** all enough to fit on a desk. The Altair 8800 was the first PC. Apple Computer made its first PC in 1977. IBM made its first PC in 1981.
WHO INVENTED COMPUTER PROGRAMS?
Computer programs are sets of instructions that tell a puter what to do. Many people worked on early puter programs. The first programs were very hard to write and understand. They were extremely long strings of zeros and ones.
American naval officer and mathematician Grace Murray Hopper in 1952 wrote the first program that turned English puter instructions into the strings of ones and zeros that make puters work. These programs are called pilers. In 1957, she helped develop the first programming language that panies could buy and use. It was called FLOW-MATIC. Hopper was also the first to use the word bug to mean a problem with a puter. She found a moth trapped in one of the puters she worked with. She taped the moth into her notebook and wrote, “First actual case of a bug being found.”
LATER DEVELOPMENTS
As puters have bee more powerful and widespread, operating systems have bee extremely plex. Few people can use a puter without one. Scientists at AT&T developed an operating system called UNIX in 1969. UNIX and related operating systems such as Linux are popular at universities and among puter professionals. In 1975, Bill Gates and his friend Paul Allen wrote a program for the Altair 8800 and founded the Microsoft Corporation. Microsoft later developed the DOS and Windows operating systems used on many home and office PCs.
Computers keep getting *** aller and more powerful. Personal puters that fit on a desktop today are more powerful than early “superputers” that filled entire rooms. Cell phones and watches contain tiny puters that can store information such as telephone numbers, addresses, and appointments. These devices allow you to surf the Web and play games. Many puter experts think that puters have only begun to make their mark on history.
