Motherboard system components- Bus architecture

Question 1

In the early days, what dominated single file serial connections?

Answer 1

parralel communication pathways (made up of multiple sychronized wires)

Question 2

what shift was there towards?

Answer 2

Serial communications

Question 3

what happened once engineers created transmitters and recievers capable of sustaining data rates of usually parralel comm?

Answer 3

they found no need of tieing pathways togeteher

Question 4

whats the downside of parralel comm ?

Answer 4

loss of circuit length, distance of signal, amount of data moved per time

Question 5

whats the only limitation of serial circuits?

Answer 5

The cpabaility of the trancievers but grows over time thanks to tech

Question 6

examples of specs of serial comm that dominate?

Answer 6

sata, usb, ieee1394- firwire, pcie

Question 7

parralel comm works on the basis of a bus, what does bus mean in this sense?

Answer 7

a common collection of signal pathways at sychronised rates that communicate over related devices within the computer system

Question 8

expansion slots are incorprated at certain points to connect what?

Answer 8

generally arbitary and pci

Question 9

what are the other types of buses?

Answer 9

more internal type to allow communication between cpu and compononents with which data must be exchanged

Question 10

what was the problem with parralel comm?

Answer 10

they had to be send through many pins in parralel at synchronised rates but became harder to increase rates because was harder to synchronise

Question 11

which one can move data at higher rates? parellel or serial comm?

Answer 11

serialll

Question 12

how can buses be rated?

Answer 12

through their bus speed

Question 13

what are bus speeds?

Answer 13

the rate of communication
