First Programmable computeer
Z1 (originally named V1), began development in 1936 by Germany's Konrad Zuse in his parents living room and today is considered the first electrical binary programmable computer. The Z1 had 64-word memory (each word contained 22 bits) and a clock speed of 1 Hz. To program the the Z1 required that the user insert <a href='http://www.computerhope.com/jargon/p/punctape.htm' >pun -

The First Digital Computer
Short for Atanasoff-Berry Computer, the ABC started being developed by Professor John Vincent Atanasoff and graduate student Cliff Berry in 1937 and continued to be developed until 1942 at the Iowa State College (now Iowa State University). On October 19, 1973, US Federal Judge Earl R. Larson signed his decision that the ENIAC patent by Eckert and Mauchly was invalid and named Atanasoff the inventor of the electronic digital computer. -

Eniac
The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. Although the Judge ruled that the ABC computer was the first digital computer many still consider the ENIAC to be the first digital computer. -

The First Stored Program Computer
The early British computer known as the EDSAC is considered to be the first stored program electronic computer. The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game. -

The first PC (IBM compatible) computer
In 1953 IBM shipped its first electric computer, the 701. Later IBM introduced its first personal computer called the "IBM PC" in 1981. The computer was code named and still sometimes referred to as the "Acorn" and had a 8088 processor, 16 KB of memory, which was expandable to 256 and utilizing MS-DOS. -
The first Transistor Computer
The TX-O (Transistorized Experimental computer) and first transistorized computer is demonstrated at the Massachusetts Institute of Technology in 1956. -
The frst Minicomputer
In 1960 Digital Equipment Corporation released its first of many PDP computers the PDP-1.
Short for Programmable Data Processor, PDP was a series of computers developed by Digial. The first PDP and first minicomputer was the PDP-1 and was developed in 1960, had five-megacycle circuits, a magnetic core memory, and fully parallel processing with a computation rate of 100,000 additions per second. The PDP series included the PDP-4, PDP-6, PDP-7, PDP-8, PDP-9, PDP-10, PDP-11, PDP-12, PDP-14, and PDP -

The first Personal computer
In 1975 Ed Roberts coined the term personal computer when he introduced the Altair 8800. Although the first personal computer is considered to be the Kenback-1, which was first introduced for $750 in 1971. The computer relied on a series of switches for inputting data and output data by turning on and off a series of lights. The Micral is considered the be the first commercial non-assembly computer. The computer used the Intel 8008 processor and sold for $1,750 in 1973. -
The first Workstation
Although never sold the first workstation is considered to be the Xerox Alto, introduced in 1974. The computer was revolutionary for its time and included a fully functional computer, display, and mouse. The computer operated like many computers today utilizing windows, menus and icons as an interface to its operating system. -
The first PC clone
The first PC clone was developed by Compaq, the "Compaq Portable" was release in March 1983 and was 100% compatible with IBM computers and software that ran on IBM computers. -
Laptop
The first portable computer or laptop is considered to be the Osborne I. -

The first laptop or portable computer
The first portable computer or laptop is considered to be the Osborne I, developed by Adam Osborne that weighed 24 pounds, a 5-inch display, 64 KB of memory, two 5 1/4" floppy drives, and a modem.
IBM PCD later released the IBM portable in 1984, it's first portable computer that weighed in at 30 pounds. IBM PCD later announced in 1986 it's first laptop computer, the PC Convertible, weighing 12 pounds. And in 1994 introduces the IBM ThinkPad 775CD, the first notebook with an integrated CD-ROM -
The first multimedia computer
In 1992 Tandy Radio Shack becomes one of the first companies to release a computer based on the MPC standard with its introduction of the M2500 XL/2 and M4020 SX computers.
