This ‘telephone’ has too
many shortcomings to be seriously considered
as a means of communication. The
device is inherently of no value to us

By changing the program (instructions), the same computer can be used to perform different function
(That’s why X-Box can be hacked to run Linux OS)
mainframes support more simultaneous programs.
But supercomputers can execute a single program faster than a mainframe
Workstation: Sun Ultra450
HP Compaq microcomputer
Apple i-Mac computer
Owing to market demand, a new spectrum of products is being developed and the boundary is becoming un-clear.
One example is the so-called “sub-notebooks” with dimension from 9 inches to 14 inches
Personal Digital Assistant
DSP: Digital Signal Processor
The machine which stores your email / web page
PCs, workstations which access mail / webpage (e.g. running I.E.)
E-Book with Dual monitor?
More environment-friendly: Solar notebook?
Only time will tell whether those concepts could survive
The raw facts and figures that are processed into information
Data that has been summarized or otherwise manipulated for use in decision makingSo, what is the common point?
Although computers differ in size, price and usage, but as mentioned earlier, they are common in a way that they all
run programs. Another common point is that computers
process data into information.
Profit / business strategy
All the machinery and equipment in a computer system
All the instructions that tell the computer how to perform a taskHardware and software
Since computer is a generic machine which is capable of doing different tasks, you need to provide the computer with command / instructions (i.e. SOFTWARE)
Thanks to the improvement
of technology. Wireless ver
is more common
Case or system cabinet
Computer circuitry that temporarily holds data waiting to be processed
Secondary storage (storage) -
The area in the computer where data or information is held permanentlyHow Computers Work - Concept #3All computers follow the same five basic operations.
