computer
History
old computer(before invent transistors)
electronic computers : its a electrical enormous work on electricity and made of vacuum tubes and it used fore calculating and for send orders and it was the start of progaming to have a language between human user and machine with automatic working tasks and orders from user and manual usage with programing languages. and it divide to :
EDSAC : and its the first computer that stores the program in memory with Binary numbers and the first to store the orders an information
EDVAC : and its the first computer it work on programmatic logic for have alanguage to make communication between user and machine
then
ENIAC : a huge computer used for calcuating and send arithmetic operations
then
vacuum tubes : somethings like lamp but it have a two used for storing the info like (0or1) long term or short term.
:warning: tip : the vacuum tubes have alot of problems :
:warning:-they have a short old.
:warning:-they are so expensive.
:warning:-they generate alot of heat.
:warning:-and they are turly big so you should had a massive place like tennise court to fit size such one computer!
manual calculators
chinese calculator: it is just a simple calculator just using pieces of rock rings to solve logical mathematical problems
mechanical calculators
its a calculating device and it also used for calculating accurately contains a mechanical wheels and tape of paper and buttons to Entering arithmetic operations and it works on electricity with manual useage and automatic working tasks
smart and modern computers (after invent transistors)

componets ccustmize and factory immediately installation
*tip : the pc (personal computer) have the same componets but it contains different of changing or customization some parts : details : -(some comuters have the ability of customize and anothe
they dont have). -(or some parts are already installe and another they dont).
