hi friends!

computer has mainly three components

1. software
2. hardware
3. liveware

computer uses some special types of languages to communicate with the user.
these languages are called programming languages.

computer's hardware can understand only the language of electricity pulses because it is operated by the electricity signals. hence we uses binary number system in stead of decimal number system.

actually binary number system can represent any information using only two types of electric signals 0 and 1
but
decimal number system need to use 10 different electric signals to represent any information from 0,1,2......,9. hence using decimal number system is more tedious than binary number system

hence we use binary number system in computer to process all type of data

I think we need a separate thread for sharing the information related to our field specially.

so what are you waiting for just do it here...

share your valuable information with us

all type of info information related to the computers, IT and ITES is heartly welcomed

feel free to give your contribution to this thread.

your information is very precious for all of us.

please do not try to divert the thread from its original topic

and please do not make it a chating thread. although chat related to computers is permissible.

let us start with the basic standard definition of the computers :

"computer is an electronic data processing device that is mainly use to perform different types of applications according to the requirement of the user"

electronic :

1. operated by the electricity
2. a device that contain ICs (Integrated Circuits) in itself.

ex: computers, television etc.

data :

1. raw fact about the entity.
2. a collection of information in the raw material form.

ex: employees details of 10 companies, list of students score cards

processing:

processing is the process of converting the useless data into the useful information

ex: getting the information of a particular employee from the employee details table

normally junk stands for the wastage material.

In terms of computers, JUNK is that type of computer related waste or useless material like CD, HDD, VDU etc. that is not in use.

you can say useless computer related material is junk.

in our field change is the only constant. technology is changing with very fast speed so a new technology which is very useful today may become useless tomorrow due to a better technology invented. and new technology replace the older one

like we are using P4 or dualcore processor now a days but before 10 years the capacity of that time's super computers was less than todays personal computers. hence you can imaging the fast change of technology.

this fast track change makes the things older very quickly. these older version of computer related material are useless for the developed countries so they dump this material into the developing countries like India.
