03 famous computer scientist
First part of the CPU.
Arithmetic Logic Unit Performs operations on data. Addition Subtraction
Charles Babbage
Began developing the Difference Engine in 1822. He was never able to finish a full scale version. However, it is still considered the first automatic computing engine capable of computing many sets of numbers and printing results.
Alan Turing
Best known for his role in WWII breaking the Enigma code and creating the Turing test.
Charles Babbage
Conceptualized and invented the Analytical Engine in 1837 which contained the first Arithmetic Logic Unit (ALU), memory and basic flow control. His son Henry partially developed the machine in 1910.
Second part of the CPU
Control unit Coordinates the computer's activities. Communication between input/output devices. Interprets instructions and determines the sequence for processing data.
Charles Babbage
Father of Computing" A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.
Ada Lovelace
First to full recognize the potential of Babbage's machines and first computer programmer.
Alan Turing
In 1936, created the Turing Machine. It printed instruction like symbols on magnetic tape similar to a human solving a math problem.
CPU
Is a small flat square that is connected to the motherboard, generally referred to as the processor. Is the brain of the computer and controls the manipulation of data. In small, mobile devices, is called a microprocessor.
Ada Lovelace
Mother of Programming" A mathematician and writer.
Ada Lovelace
Realized a machine used to crunch numbers could be used for the computation of anything when using numbers as reputation symbols.
third part of the CPU
Register unit Stores data in cells Cells are called registers Consists of 2 types of registers General-purpose Special-purpose
Grece Hopper
She popularized the idea of machine-independent programming languages, which led to the development of COBOL. Cobol: an early high-level programming language designed in 1959 and still in use today.
Grece Hopper
She was a pioneer of computer programming and invented one of the first compilers
Alan Turing
"Father of theoretical computer science and artificial intelligence" A computer scientist, mathematician, logician, crypt analyst, philosopher, and theoretical biologist.
Grece Hopper
A computer scientist and United States Navy rear admiral.
