Program and Computer
How the programs run internally?on single computer and on server?
What is a computer: an electronic Device that manipulates information or Data.
Definition: A computer is Machine made of devices that enable you to enter data (input) , process it(CPU), store it(Memory) and output the result.
Logic Gate:
AND , OR, NOT
We use transistors to build logic gates(3)
Transistors are connected in specific wires to create special circuits called logic gates. Logic gates can be combined to form calculations, make decisions and remember information.
Microprocessor is responsible for running software or applications like web browsers... together with Operating System.
An Integrated circuit that contains all the functions of CPU of a computer.
4 bit to 64 bit Microprocessor:
CPU or Microprocessor is the Brain of computer.
Clock Speed or Clock Rate : No of instructions per sec.
One CPU Cycle
Fetch -->Decode-->Execute-->store/write back to cache
instructions cycle/execution cycle/clock cycle.
1GHZ= 1 billion clock cycles/sec
2GHZ=2 billion clock cycles/sec
Generations:
1. Performance[turbo boost,hyper threading]
2. Cache Memory
3. No.of cores[dual core, quad core[Multi tasking]]
---> 32 bit
2 power 32 = 4 GB (processor can store 4 Giga bit)
64 bit
2 power 64 = 16EB(exa byte)
RAM : will give data to CPU
max: 128GB RAM
facebook requires: 300 MB memory example
