Technology advances (moore's law)
Small is powerful (technology tends to become smaller and more powerful... Though this makes user
interface more of an enigma: how do we interact with/use increasingly smaller devices?)
The network is the thing (it's not just the machine... It's its ability to network.
e-cycling= recycling of electronic hardware. Implications: we're going green, bigger and bigger concern.
Mouse, keyboard, touch screen, scanners, etc.
Central processing unit (CPU)
Brain: processes, analyzes, goes through procedures, stores information in storage.
CPU and data bus (cache memory)
Fast processing of data once it's in main memory (once in ram)
Main memory (RAM)
Hold multiple programs, process large amounts of data
Main memory takes info that has come from memory and then processed by the cpu
Store many large programs, store many large files, swap files in and out of memory (storage/harddrive)
Special function cards
e.g. Video cards. Augments computer's basic functions (add-ons)
Monitors, speakers, etc.
Saves data and programs
Moves info from RAM to CPU
Binary digits=bits=8 to a byte
Operating systems manage operating processes (organizes what happens and allocates computer
Unix for engineers
Linux for open sourcers
Windows for business
Leopard for graphic designers
Horizontal market application vs vertical market application
