HARDWARE REVOLUTION 1981 -Osbanne was introduced. It has two floppy drives and no hand disk. It also has the operating system called CP/M (Controlled Processor or Minicomputer). -CPM is a word processing software called wordstar and spread sheet software called supercal. -In August 1981,IBM launched the IBM PC that has an operating system called DOS (Dist Operating System) that has provided by Microsoft Corporation. It has a RAM of 16K with two floppy disk drive. - Xerox Corporation introduced Xerox Star with the use of the mouse as an input device.

1982 -the sun Microsystem Inc. was established and established the 1st workstation called SUN1 Intel Corporation also released it’s 16-Bit microprocessor.

1983 -Compag released the 1st successful 100% IBM-PC compatible.

1985 -Intercorporation introduces the 32-bit microprocessor.

1986 -IBM Corporation introduces the 1st laptop computer. -In the same year, CD-ROM technology introduces as a promising storage device in an international conference held in Seattle, Washington, U.S.A.

1987 -The bass design of the Extended Industry standard. Architecture is introduced to compete with IBM’s microchannel architecture. -Video Graphical Array (VGA) interface was introduced by IBM Corporation that offers 256 colors with 320x200 resolution. -HP-Deskjet printer was also introduced by HP (Hewett-Packard)

1988 -Steve Jobs owner of Next Inc. and the cofounder of apple Comp. introduces the first PC to use object oriented Programming and used CD-ROM drive instead of the floppy drive.

1989 -Apple released Powerbook. -Apple along with IBM and Motorola signed an agreement to design and produced RISC (Reduced Instruction Set Computing),OOP System and develop common multimedia standards. They develop the Power PC.

1992 -IBM released think Pad.

1995 -Intel introduces the Pention microprocessor.

1996 -The start of the world-renewed PDA (Personal Digital Assistant).

1997 -Introduces Pentium II. -DVD digital video disk was also introduced.

1998 -Pentium II Celeron was released.

1999 -Pentium II is released. It enhances the websites graphic application. -Apple Corp. release Mac.

2000 -AMD and Intel Corp. introduces to releasethe world’s first microprocessor to run in 1 GHz speed.

2001 -Apple Comp. introduces iPod, the first music player with an internal memory of 56b that can store 100 songs.

2003 -WI-Fi wireless Fidelity with the use of your laptops without using wires.

2005 -Bluetooth enabled devices allow sharing of text, videos, music or files across broad range of devices such as your cell phone, PDA or iPod.

2006 -Intel care Duo is the emerging microprocessor technology in the market.

Central Processing Unit (CPU) -also called as the microprocessor and is the brain of the computer. -it interprets and carry out instructions or commands in each program or software. -it also does arithmetic and logical operations and connect with the other parts of the computer.

RAM -computer’s main memory. -its integrated circuits that can be used to store program, instructions and data temporarily. -the computer access information through RAM with the use of unique memory address (memory location). Scheme is applied so that the computer would easily find were to retrieve the data or information needed. -a volatile type of memory because whatever which we stored into it during the time we use the computer will vanish completely when we turn off the computer. -the higher the bytes of your RAM, the better that it can perform task faster and better.

ROM -a non volatile type memory meaning the programs and data stored are permanent. -the computer can read info or instruction from it, but it can never write or store any new info on it. -use to check subsystem of the computer hardware in order to ensure that on the basic parts are working and in good condition, otherwise the ROM won’t let the computer to function.

CMOS -Complementary metal –oxide semi-conductor. -a chief used to hold and record all basic set up of the computer system such as the number of hard disk installed, the system date and if other computer peripherals are connected to it such as modem, sound cards and others. -all settings of hardware are recorded in the CMOS. -the personal computer has a CMOS that uses battery to operate that is why it has an update date and time even were not using our computer in a day or a week.

What is an OS? -is a collection of programs that perform a variety of tasks and functions. -the task involve communicating with the disk, drives, printers, hard disks, CD ROMS, monitor, mode m and other peripheral devices. -Performs memory management task such as keeping track of how the memory of the computer is being used so that no job will conflict with another job performed at the other parts of the computer.

Diff. Kinds of Operating System -the disk operating system (DOS) -In 1980 and early 1990s DOS dominates the market as a standard operating system of Personal Computers. -designed with a character-based user interface meaning we have to type a command to perform a particular task, like copying, deleting, transferring and running a certain program or software.

Microsoft Windows O.S. Windows 95 -used by computers in early 1990s who wanted a GUI type of operating system. -Put all the data communication in a single screen icon, these are email, downloads and internet access. -supports the plug and play feature.

Windows 98 -an update of windows 95, it has the inclusion of the internet Explore.

Windows ME (Millennium Edition) -offers ore enhancements such as digital video editing, improved multimedia support and capabilities, and enhanced internet features.

Windows 2000 Professional -combines the user friendly interface of Windows 98 and the networking power of Windows NT.

Windows NT -released before Windows 95. It was originally designed as the successor of DOS but it turned out to be and repositioned as a high end operating system for powerful workstation and network server.

Windows XP -desktop has more 3 dimensional 3D look. It supports 64-bit CPU. -with its digital media support, the user can take advantage of the video and audition rendering for multimedia projects and digital broadcast support. -with more enhanced plug and play. -Internet connection sharing the user can connect multiple PCs to the internet via a single connection.

Windows Vista -Finding the file in a few quick clicks. -Keeping Photos organized. -Create a customized movie. -keeping track of your music. -Watch and record tv drama. -Surfing multiple web at once. -more system security. -see everything you open lately.
