hello,guys..(0.0)..we meet again..though i'm not that expert in IT,but i know that is my responsible in learning it..well,i'm not going to learn it alone..because i'll share it with all..so,everyone will be clever just like me.. :p..straight to the point,i will continue what i've learn in my favourite class.
HARDWARE
the equipment that process data to create information.
(not only computer considered as hardware.keyboard,mouse,monitor,etc. also consider as hardware)
about 4 types of computers
- supercomputers:most powerful and high-capacity computer used by very large companies
- mainframe computers:not very powerful but have great processing speeds and data storage
- minicomputers:used by medium-sized companies for specific purpose
- microcomputers:most widely used.eg: desktop,notebook,tablet PC,handheld computers
4 basic categories of microcomputers hardware:
system unit
input/output device
secondary storage
communication
enough with hardware..let we proceed to 'data' which is also 1 part of information system..why we have to know about it? (^.^)..to burden our mind,i guess..???...just kidding
DATA
raw and unprocessed facts which include text,numbers,images and sounds.once the data processed, it will become information.when save in files,this data can be used directly as input for system unit.probably everyone will recognize all of these files..
- document
- worksheet
- database
- presentation
