How Computers Changed The World

1. How Computers Changed The World By Kj Chung

2. What is a computer? • A computer is an organized setting of hardware and systems, and the “ computer “ is the operator. • Personal Computers are the same as a normal computer except they use a variety of extra software. • Normal computers which are not personalized for entertainment, are more accustomed for work.

3. Personal Computers • A personal computer [PC] is a computer made so that the user can easily modify the system to their personal needs. • Computers are generally named from a manufacturing company such as, “Macintosh” or “Pentium”. • These computers may be different, but all computers share common traits, such as the “microprocessor”. [The “brain” of the computer]

4. History • The first computers were enormous, and filled up a room easily. • These computers required huge amounts of power, and they also required special needs. • One example was temperature, with the correct temperature the computers could 0perate with stability.

5. Advances in Technology • In the 1950’s, the “integrated circuit” was invented and it changed the economy of the computer market. • The IC allowed computers to control “transistors” [controls] faster and every year from that, the number of controls the IC could handle doubled. • In addition to that, IC’s were smaller and were faster then a large computer software.

6. Modern Computers • Today’s computers can read CDs or DVDs in their system without the proper player. • Also, computers have become mobile. • Mobile computers are extremely portable, but they have their own setbacks. • Portable computers do not have a long battery life, and need a special design for ventilation in order not overheat.

7. Communicating • Computers can record sounds and voices with a microphone and keep it as a file. • Computers can also send emails using the Internet with ease, which was a lot faster then the traditional mailing.

8. Computer Systems • Two high school friends, Paul Allen and Bill Gates, created a software for computers and made the Microsoft Corp. • Microsoft is the world’s leading independent software developer. • The International Business Machines [IBM] is a leading company of computer industry.

9. Microsoft • Microsoft created “Windows XP” which was a huge success due to its capabilities which increased over time. • After XP, Microsoft released “Microsoft Vista” which was a more secure software then XP, with increased potential. • Soon, nearly all computers became “user-friendly” and more and more people began to use computers.

10. The Internet • Computers connect to the internet by using either : “T” [trunk] carriers which sent digital signals, telephone lines carrying the signal, or Wi-Fi [Wireless Fidelity] • As the internet became more common, it soon became a main source for entertainment source for many. • People used it for games, videos, blogs, and much more.

11. Computer Aided Manufacturing • CAM is a form of manufacturing, when machines “communicate” to do a task. • This began in the 1950’s and began to take over the menial jobs of human workers. • Computers soon helped the manufacturing process go faster and easier with less mistakes.

12. Computer Aided Manufacturing • In the 1950’s, the computers were simple numerically controlled machines. • These computers had a set of coded instructions in them, which were in punched paper tape. • However these computers were not as advanced and this progress required a number of computers.

13. Computer Aided Manufacturing • A computer from today can control a number of other machines, rather needing a number. • A computer engineer can easily change the programming to make the machines to do another task. • The most advanced systems can do tasks such as ordering a shipment, scheduling, and tasks people are usually assigned.

14. This chart shows the percentage of people who owned computers in America during different time periods.

15. Computer Facts • Some portable computers can be tenth the size of a notebook. • Every year, the capabilities of most computers double and operate better. • A computer’s memory has increased over time, and the size of the computer has gotten smaller, but has increased capabilities as well.
