first electronic computer was developed in?
1946 designed by J presper eckert and john W mauchly
who invented integrated circuit?
1965 jack kilby
this generation involves computer intelligence which associated with the (AI) artificial intelligence
4th gen.
what makes computer work?
Computer is an electronic device that manipulate information or data
Different types of computer
Desktop computer - laptop computer - battery powered com tablet computer - handheld com. smart phones - handheld telephones wearables - fitness trackers smart tv's - latest television
this considered to be the first generation computer
ENIAC
This information only do arithmetic operation zuch as addition and subtraction of up to 10 digits
Eniac
five generation of computer are briefly defined (pepito 2012)
First generation computer (1946 - 1959) Second generatiom computer (1959 - 1965? third generation computer (1965 - 1971) fourth generation computer (1971 - 1980) fifth generation computer (1980- onwards)
general classifications of computer are:
Personal computer- small single user workstation- powerful single user minicomputer- multi user 10 to hundreds mainframe- powerful multi user hundred to thousand supercomputer- extremely fast
ENIAC means?
electronic numeric integrator and calculator
In this generation remote processing time sharing and multiprograming operating system were used
Third generation
this was used as the interior section of computer?
Transistor
smaller faster and more dependable than the vacuum tube af the 1st G?
Transistors
small portable storage devise often refer to pen drives thumb drive or jump drive
flash disk drive
its a flat round and portable mental disc
compact disc
it has the abily to store retrieve and process data, it also contain both hardware components and software applications
componenst of a computer
it a single chip knows as the
microprocessor
system unit also called?
motherboard
a hardware component that transmits information to one or more people
output devices
it send back the administered data to the user
output devices
it and i7 only have
r cores
a computer can be utilized with only processing memory input and output devides
storage devise
the enclosure composed of the main elements of a computer that are used to administer data
system unit
they generate less heat and consumed less electricity but were still very costly
transistor
to compare a computer intel core i3 processor
two cores
