What jis ja jcommunications/data jbus? j- jANS✓✓-It jis ja jcommunication jsystem
jthat jtransfers jdata jbetween jcomponents jinside ja jcomputer jor jbetween
jcomputers.
What jis ja jcommunications jprotocol? j- jANS✓✓-It jis ja jsystem jof jrules jthat
jallow jtwo jor jmore jentities jof ja jcommunications jsystem jto jtransmit jinformation
jand jdata. jAn jexample jthat jexists jin jthe joutside jworld jis jsending jan jemail
jwhere jthe jrules jare jan jemail(receiver), ja jsubject, jand ja jbody.
Difference jbetween jserial jand jparallel jcommunications. j- jANS✓✓-- jSerial
jtransmit jbit jby jbit
- jParallel jtransmit ja jbyte(8 jbits) jor jcharacter
Parallel jBus jCommuncations. j- jANS✓✓-PCI, jIDE/SATA, jIEEE j1284(Centronics)
IDE jand jSATA jPorts. j- jANS✓✓-SATA, j(Serial jAdvanced jTechnology
jAdvancement) jis ja jcomputer jbus jinterface jthat jconnects jhost jbus jadapters jto
jmass jstorage jdevices jsuch jas jHDD, jSSD, jor joptical jdrives. jIDE, jIntegrated
jDrive jElectronics jis jsimilar jto jSATA jbut jslower.
BIOS jChip jand jBattery. j- jANS✓✓-It jis ja jROM jchip jthat jallows jyou jto jaccess
jand jset jthe jcomputer jat jthe jmost jbasic jlevel. jThe jbattery jis ja jvery jlow jpower
jsemiconductor jthat jis jused jto jsave jthe jBIOS jsettings.
Northbridge j- jANS✓✓-The jfunction jof jthe jnorth jbridge jis jto jhandle
jcommunication jbetween jthe jCPU jchip jitself jand jwith jthe jmemory jbus jand
jgraphics jbus j(PCIe jx16 j& jx8) jcontrollers.*High jPerformance*
