First Personal Computer The Apple II was the first true "personal computer" it was factory built, in-expensive and easy to learn and use. Provided with the most extensive set of software and low cost floppy disks, the Apple II was also the first personal computer capable of color graphics and easy modem operation
9
First Killer Application Visicalc (Visible Calculator) Development of the Visicalc spreadsheet program created a business tool that made adoption of Apple II a regular part of business.
10
First Intel PC Computer The MITS Altair was the first 8080 based kit microcomputer. It was first introduced in the January, 1975 issue of Popular Electronics magazine as a construction project. Although not the first available microcomputer, it was the start of the PC industry.
11
First PC Computer The original IBM Personal Computer was released in August 1981. It cost a little under $3000 and came with 64Kb of Random Access Memory (RAM), 40Kb of Read Only Memory (ROM) which included a BASIC interpreter, a 160Kb floppy disk, version 1.0 of MS-DOS, and a cassette interface.
12
XT Computer In March 1983, the IBM Personal Computer XT (eXtended Technology) was unveiled with a built-in 10 MB fixed disk.
13
XT Computer It consisted of a Central Processing Unit (CPU) which was the Intel 8088 running at 4.77 MHz, some RAM, some ROM containing the machine's Basic Input Output System (BIOS)
14
AT Computer In 1984, the IBM AT (Advanced Technology) Using an Intel 80286 processor, a 16-bit bus, a medium- speed hard disk and a 1.2 megabyte floppy disk drive
15
Second Killer Application LOTUS 1-2-3 Another spreadsheet program developed from the un-copyrighted Visicalc program originally on the Apple II computer
16
ATX Computer An open PC motherboard specification by Intel ATX is a development of the Baby AT specification with the motherboard rotated 90 degrees in the chassis. The CPU and SIMM sockets have been relocated away from the expansion card slots meaning that all the slots support full-length cards.
17
Modern Computers ATX computers are the current standard form-factor for PCs INTELAMD

Computer Language DigitalAnalog Binary System (2)
19
Computer Language Bit = 0 or 1 Byte = 8 bits Byte = Character (ABC, 012, etc)
20
Computer Language Kilobyte (KB/K) = 1,024 bytes 2 10 Megabyte (MB/M) = 1,048,576 bytes 2 20 Gigabyte ( GB/G ) = 1,073,741,824 bytes 2 30
21
Computer Language Hertz a unit of frequency of electrical vibrations equal to one cycle per second
22
Computer Language MHz – Megahertz Mega = Million GHz – Gigahertz Giga = Billion THz – Terahertz Tera = Trillion
