The document discusses the evolution of computers from their early invention to modern times. It describes how early computers were large, expensive machines only affordable to institutions and the wealthy, while modern computers are small, affordable devices ubiquitous in everyday life and business. The core components of computers like the CPU, RAM, hard drives and other parts are also explained.

1. The Evolution Of Computers Jacob Sedgwick

2. Overview Powerpoint Conclusion Application Class Activity

3. Thesis While computers have been around for decades their components inside keep evolving. In order to keep up with this evolving technology a Network Administrator will need to receive the proper certifications and training.

4. Personal Relevance

5. What is a Computer? A computer is a electronic device that stores and processes data, according to the instructions that the user gave it

6. Why Computers Are Important? Computers are very important in this day in age because they control almost everything we do and they are very accurate Computers are also very fast & they can accomplish many tasks all at the same time

7. The history of the Computer

8. Invention of the First Working Computer The design for the first computer was made by Wilhelm Schockard Schockard’s computer was a calculating machine designed to calculate the distance between the planets His machine also could add or subtract up to six digit numbers http://upload.wikimedia.org/wikipedia/commons/5/5a/Schickardmaschine.jpg

9. First Programmable Computer The first programmable computer was invented in May 1941 by Konrad Zuse Zuse’s computer was used to solve complicated math Zuse’s Computer weighted over 2,500 pounds The internal parts are similar to the modern computer

10. First Programmable Computer

11. Computers in the 1970s Early computers were all hand built They were slow and could only perform simple problems These computers were only affordable to the upper class They were expensive

12. Computers in the 1990s The 1990s was when computers were first widely commercially available They were cheap enough that the average consumer could afford one The computers were not very powerful but they could complete complicated tasks

13. Modern Computers Today Most computers made today are cheap, portable, & lightweight Compared to computers from the 1970s, computers today are thousands of times more powerful and cheaper

14. Time Line 1930 2010 1970 1975 The Company Microsoft & Apple were founded

15. Working Safely When Repairing a Computer

16. Work Environment Always work in a clean, dusk free environment When working with circuit boards always wear a anti-static wrist strap Lay all parts removed on an antistatic mat

17. Always Unplug The Computer Unplugging a computer helps protect you from a potential deadly electric shock

18. Remove all Hand Jewelry Most Hand Jewelry is conductive which can result in a electrical shock Hand jewelry should also be removed when working with moving parts

19. Avoid Capacitors Capacitors are miniature “Batteries” that can hold a electrical charge after a computer is disconnected from power When working on a computer always disconnect the power then wait a few minutes for the capacitors to discharge

20. Never Attempt to Service Non-Serviceable Parts Non-serviceable parts are parts that are not designed to be replaced by anybody except the manufacturer ExamplesOptical DrivesHard DrivesMonitorsComputer Power Supply’s Optical DrivesHard DrivesMonitorsComputer Power Supply’s http://maven.smith.edu/~orourke/103/CSC103_Pictures_files/CSC103_PowerSupply.jpg

21. Basic Computer Components

22. Major Computer Components CPU (Central Processing Unit) RAM (Random-Access Memory) Hard Drive Motherboard Computer Case Video CardSound CardOptical DriveMonitor Network Interface Card

23. Central Processing Unit (CPU) It is the most important element of a computer The CPU is the “brain” of the computer CPU is the part of the computer that controls and executes all tasks that the computer is trying to perform

24. Heat-sink It is a device that removes unwanted or excessive heat They are usually make out of Aluminum They can be either liquid or air cooled

25. Random-Access Memory (RAM) RAM is a type of computer chip that stores all of the dynamic data on the computer By storing all of your dynamic date in RAM, it makes data access faster than a hard drive http://im3.ebidst.com/upload_big/6/4/4/1214619692-30617-0.jpg

26. Hard Disk Drive A hard drive is a device that magnetically stores data on a spinning disk It is a non-volatile type of storage

27. Solid State Drive It is a data storage device that uses solid-state memory to store data instead of a spinning disk The technology has been around for years, but only available to the military (SSD)

28. Motherboard It is a printed circuit board that holds all of the principle components that make up a computer

29. Video Card It is a expansion card that generates images to be displayed on a monitor Many modern video cards have capabilities to display 3D images, and live TV

30. Sound Card It is a card in the computer case that translates computer code into audio signals Most computers have sound cards built into the motherboard, but some require a separate card

31. Optical Disk Drive It is a type of disk drive that uses laser light to read to and from disks Most drives today commonly can read & write to disks The most common name for a optical disk drive are: CD burner & DVD burner

32. Computer Case It is the enclosure that holds all the main components for a computer It is also the protective covering that prevents the components inside from getting damaged

33. Network Card A Network Card is a device that enables a computer to communicate with other computers on a network or the internet (NIC) Wireless Wired

34. Printer It is a device that accepts text or graphics from a computer and outputs the information on paper

35. Monitor It’s a device that displays images that are generated by a computer There are two types of Computer Monitors http://star-techcentral.com/archives/2007/5/29/prodit/Philips_1b.jpg http://www.samsung.com/us/system/consumer/product/2009/08/22/ls24kizkfvza/2494SW_Front_Medium.jpg

36. Screen Burn-In

37. Types of Monitors

38. CRT Monitor A CRT monitor creates a picture by that it has many rows of colored dots (Cathode Ray Tube)

39. LCD Monitor One of the most popular flat screen monitors Th (Liquid Crystal Display)

40. Conclusion I learned more about how and when computers were invented My project had changed my opinion on computers because I never knew how big of a major role that computers played in our daily lives
