A device driver is software which allows a peripheral to communicate with the other components of a computer (eg OS, other software apps, other hardware components etc etc).
Just like how a car driver is useless without arms, a peripheral connected to a computer is useless without a device driver.

part c of parrallel serial bit-
Serial - transmits 8 bits (1byte) in a row through 1 cable
Parallel - transmits 1byte at a time through 8 cables, 1 bit through each cable (hence parallel)
For both of these, data can only travel in one direction through each cable/pin.
Half-Duplex - data only travels in 1 dir at 1 time
Full-Duplex - data travels in both dir at same time
To acheive full-duplex in serial and parallel the number of pins/cables need to be doubled.

The marking guidelines stated confusion between serial/parralel and simplex/half-duplex/duplex modes. But i guess if you used em correctly, it would get ya the extra marks.

Configuration? Doesnt that just allow for changing the settings of how a component communicates with the rest of the computer, or how it behaves in a certain situation? Like say modem configuration, things like error correction method and stuff like that?Linda N said:
EDIT: IDE...hmmm (runs for cover coz he doesnt really know.)
Hehe i think its an interface for mass storage devices to transfer files, with the controller in the actual drive (eg Hard drive).
IDE stands for Intelligent Drive Electronics
EDIT 2: What a fluke it does stand for that :S

Umm it stands for both (see webopedia.com)
Examples of configuring the modem?
You can change parameters such as
Flow control: outlines method of handshaking
Parity Bit: states presence of parity bit or not
Baud Rate: number of electrical symbols sent per second
BPS: number of bits per second
Start/stop bit: indicates presence of start/stop bit for asynchronous transfer
Hope thats what you mean :|

Whats that matrix thing!

Damages the software industry, causes programmers to go bankrupt as everyone steals their software without paying for it...umm...
The matrix thing is an new online game which is being tested in the us at the moment. "http://thematrixonline.warnerbros.com/web/index.jsp"
9 time out of 10 all the functions of the programs illegaly being used have functions in which aren't turned on
software companys loss of income (not that some of them need iteg microsoft)

- The chance of being caught and coping a huge fine
- The lost of a job if piracy is done in the workplace
- Lawsuits
- Goal sentence
- Free PROGRAMS !!!! (saves the individual user money but i would put that as a answer in the HSC )
- The company loss of money can affect the amount of jobs available which raises the cost of the individual program to make a living which in return raises the cost of software which then raise the rate at which piracy occurs

we dont know yet aye? Last year it was 4000 odd soo...anyways another question...
