Involves managing, processing and communicating information.
Two types of Computing
Centralised Computing
Distributed Computing
Advantages
Disadvantages
Mainframe Computing
Sophisticated machines based on vacuum tube technology
Personal Computing
Smaller size machines
Designed for personal usage
Networked Computing
Computers interconnected using small networks
Eg. ARPANET
Extra Stuff
Mersenne Primes → Primes of form 2^n - 1 → Used in elliptical curves.
The GIMPS Project → Allowed users to share their CPU/GPU computation → Identified 52nd Mersenne prime.
SETI → Search for extra terrestrial existence → Analysis of radio waves → Users were able to contribute their CPU computation.
Grid Computing → distributed system model that connects multiple independent, often geographically dispersed computers over a network to act as a unified "virtual supercomputer" capable of tackling massive computational tasks
