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
