1. The Evolution Of The Desktop Computer By Nicholas Bland

2. A desktop is a type of personal computer that is immobile

3. Hardware Software Price SpeedUses CHANGES OVER TIME

4. 1972-the microprocessor The microprocessor is a computer processor that incorporates the functions of a computers central processing unit (CPU) on a single integrated circuit

5. 1973-Xerox alto The first computer with a mouse Screen Large 1 MHz

6. 1974- the Altair Input by way toggle switches Output by way of LED light CPU-Intel 8080 OS- CP/M basic 2 MHz $400-$600

7. Mid 70’s-The Apple 1 Steve Jobs, Steve Wozniak Microprocessor CPU- MOS 6502 1MHz $666

8. All-in-one PC (AIO) Monitor built into console Space consolidation Lack of upgradability

9. 1977 Commodore PET Personal electronic transactor Early All-In-One 9 inch display screen OS- basic in ROM CPU-MOS 6202 1 MHz $795

10. 1979- The Apple II Color display First User friendly PC Expansion Slots for customization OS- WOS integer basic CPU- MOS 6502 1 MHz

11. Desktop customization describes software that is specifically developed for a specific organization or user

12. 1981- The IBM 5150 Featured MS-DOS Operating System Became the Standard CPU- INTEL 8088 OS- MS-DOS 7.44 MHZ $1,500 - $2,000

13. Standardization- enables computer users to use the same software on computers by different manufactures

14. Early 80’s Apple Lisa Graphical User Interface 12 inch screen OS- Apple Lisa GUI CPU- Motorola 68000 5 MHz $10,000 Apple Macintosh Graphical User Interface 9 inch scree OS- Apple Macintosh GUI CPU- Motorola 68000 7 MHz More Affordable $2,500

15. Graphical User Interface (GUI) –Allows users to interact with their computer by means of icons and graphical displays as opposed to text commands

16. Became the new standard GUI Conflict with apple begins 1985-Microsoft Windows

17. Hardware Microprocessor Mini tower Mid tower Tower Monitors All in ones Larger screens

18. Software Standardization Customization GUI

19. Speed of the Desktop Average speed of a desktop is 1.5-2.5 GHz The average speed of a desktop in 1970s was 1-2 MHz

20. Price The price of a desktop is now is usually between 275 and 1600 The price of a desktop in the 1970’s would range from 500-10,000

21. Practical Uses Then Advance calculation Now Wide range of functions
