In this age, the first large-scale automatic digital computer was created.
Give its name and when and who
Electromechanical Age
- Mark 1
- 1940 by Harvard University
8ft high, 50ft long, 2ft wide, and weighed 5 tons computer
Mark 1 - The first large-scale automatic digital computer
Year of Electronic Age
1940-present
This age is what we currently live in
Electronic Age
Characterized by the development of the ENIAC
Electronic Age
What is ENIAC
The first high-speed, digital computer
These computers use vacuum tubes and punch cards like the ENIAC and Mark 1
First Generation Computers
Rotating magnetic drums were used for internal storage
First Generation Computers
These computers replaced vacuum tubes with transistors, punch cards were replaced with magnetic tape,
Second Generation Computers
Rotating magnetic drums were replaced by magnetic cores for internal storage.
Second Generation Computers
During this time, high-level programming languages were created such as FORTRAN and COBOL
Second Generation Computers
These computers replaced transistors with integrated circuits
Third Generation Computers
Magnetic tape was used throughout all computers
Third Generation Computers
Magnetic core turned into metal oxide semiconductors
Third Generation Computers
Actual operating system showed up around this time along with the advanced programming language BASIC.
Third Generation Computers
The latest generation of computers which uses CPUs
Fourth Generation Computers
The first personal computer called Apple II was developed and the graphical user interface (GUI
Fourth Generation Computers
Still in development up until today
Fifth Generation Computers
What generation where a computer have the power of human intelligence
Fifth Generation Computers
