Abascus - ANS Was the first ever computing device developed in babaloynia over 5000 years
ago known as the "finger-powered calculator".
Is still used in some parts of the world
Algorithm - ANS Is a set of operations and rules used to perform calculations or other
problem-solving operations usually done by a computer.
For instance, they were used to find the greatest common divisor of two numbers
Early calculators - ANS Manual - eg, slide rule calculators were used in science and
engineering until later replaced by pocket calculators (modern calculators)
Mechanical
Jacquard Loom - ANS A mechanical loom used to create complex patterns in cloth quickly
and accurately.

, This was done using punch cards which carry instructions that tell computers the calculations
needed to perform a certain function. They were later used for coding in computers.
This machine was the foundation and start to computer technology.
***Was not a computing device
George Boole - ANS -Invented Boolean Algebra
-Made logical foundations of digital computing
Calude Shannon - ANS -Father of modern technology
-Introduced Boolean algebra in the application of computing computers
-Established key principles "A Mathematical theory of communication" for encoding that
allowed information to be transferred electronically
Von Neumann Architecture - ANS -A processor where data and instructions are stored in the
same memory
-Consists of CPU, memory, mass storage, Binary internal coding
-Still the basis for modern computers
Engima Machine (Germany) - ANS -Was the most sophisticated coding machine
-Germans thought it was unbreakable as the used it during WW2 to transmit secret and
important messages
EINAC -"Electronic Numerical Integrator and Computer" - ANS -First ever general use
electronic computer
-Was big and bulky as it used many vacuum tubes to control the flow of electronic signals
-Was first used by the US army
-Programming was done manually and had to be wired to perform a certain task
