-
This was another machine that was built to help fight World War 2. It was a British machine used to help decode secret enemy messages.
-
Vacuum tubes were used for storage and memory. They were often called a drum. They were very expensive to operate, and also used a lot of electricity, so they got very hot, which was a lot of times the cause of malfunctions.
-
This is the period of time where the first and earliest computers were invented/used.
-
Von Nueman designed the electronic descrete variable automatic computer with a memory to hold both a stored program as well as data.
-
Electronic Numerical Integrator and Computer was produced by a partnership between University of Pennslyvania and the US government. It consisted of 18,000 vacuum tubes and 7,000 resistors.
-
The Universal Automatic Computer was invented by Remington rand and owned by the US census bureau and General Electric.
-
The transistor was invented in 1947 in Bell Labs by Walter Brattain John Bardeen, William Shockley. A transistor is device composed of semiconductor material that amplifies a signal or opens or closes a circuit. They have allowed computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.
-
This is the second generation of computers where transistors were the main invention of the generation.
-
When assembly language replaced machine language, abbreviated programming codes to replaced long, difficult binary codes.
-
This was one of the first computing machines based on the tranisistor. They were programmed in languages such as COBOL and FORTRAN.
-
A computer universally that was universally accepted thoughout the industry, and is considered by many to be the Model T of the computer industry.
-
Magnetic disks and tape were often used for data storage for almost all of the second generation computers.
-
The invention of this was said to be "the hallmark of the third generation." They allowed computers to process faster and more efficiently.
-
The third generation of computers where the integrated circuit was the main invention of the generation.
-
Parallelism became the trend of the time and there were abundant use of functional units.
-
Integrated circuits are placed on circuit boards, which are thin pieces of bakelite or fiberglass that have electronical connections etched onto them. They're sometimes called "mother boards."
-
Invented in 1969 at AT&T Bell Labs. Provided the user with the means to allocate resources on the fly rather than requiring the resources be allocated in the design stages.
-
Ken Thompson developed simplification of CPL and called it B.
-
This took the integrated circuit one step further by locating all of the components of a computer on a little chip.
-
This is the fourth generation of computers. It extends from 1971 to the present. So these are the most updated computers and the newest computers.
-
One of the earliest computers. You could purchase one of these kits and make your own personal computer.
-
Video games started becoming more and more popular. One of the most popular ones of that time was Atari 2600.
-
IBM introduced personal computers for home and office use.
-
Switches are used to represent and control the routing of data in the form of binary digits or sometimes just called bits.
