Q

Why are conductor pairs twisted at different rates in TP cabling?

TP = Twisted Pair

A

To reduce interference

The balanced electrical signals on each pair help identify the signal against interference, but the method has limited range

97
Q

Meaning of SCSI?

A

Small Computer System Interface

98
Q

How many bits are transferred in a serial interface?

i.e. USB & thunderbolt use serial communication

A

1 bit at a time

Serial communications can achieve Mbps & Gbps speeds through the use of improved signaling & encoding methods. Back when serial interfaces were much slower, PC vendors used parallel data transmission to support better transfer rates

99
Q

How many bits are transferred in a parallel interface?

SCSI
A

1 byte at a time

Serial communications can achieve Mbps & Gbps speeds through the use of improved signaling & encoding methods. Back when serial interfaces were much slower, PC vendors used parallel data transmission to support better transfer rates.

100
Q

What bus communication does SCSI use?

A

Parallel

101
Q

Does SCSI support daisy chaining?

A

Yes

SCSI defines a command language for the host adapter to identify connected devices and their access methods

102
Q

What could SCSI be used for?

A

Internal devices & external peripherals

i.e. scanners & printers

103
Q

What is SCSI now mainly used for?

A

Internal hard drive connections

104
Q

Identify connector

A

SCSI (68-pin

While some SCSI connectors may have 68 pins, others may have different pin counts, such as 50 pins or 80 pins.

105
Q

What data rates does SCSI support?

A

Up to 320 MBps

106
Q

2 common SCSI connectors?

A
  • HD 68-pin
  • SCA 80-pin

SCA = Single Connector Attachment

107
Q

A

Molex

109
Q

What must each device in a wide SCSI bus be configured with?

A

Unique ID

110
Q

What is SCSI’s ID range?

A

0-15

Each device on a wide SCSI bus must be configured with a unique ID

111
Q

A

7 or 15

112
Q

What SCSI ID is allocated to a bootable hard disk?

A

0

113
Q

How is a SCSI bus device terminated?

The first & last device must be terminated

A

Internally or with an external terminator pack

SCSI terminator
114
Q

What part of SCSI is still used?

Parallel SCSI as a physical interface has almost completely disappeared

A

The software interface & command set

It is used on other storage technologies, like SAS

115

118
Q

What is IDE aka?

A

PATA

(Parallel Advanced Technology Attachment)

119
Q

How does the extended IDE (EIDE) transfer data?

EIDE can have different interfaces, including the standard 40-pin interface used for IDE drives and the 80-conductor cable interface for faster data transfer rates.
A

Through 16-bit parallel data transfers

This means that 16 bits are sent simultaneously over the bus

120
Q

How many IDE host adapters may a MOBO have?

MOBO = Motherboard

A

1 or 2, called IDE1 & IDE2 channel

These may also be labelled primary (PRI IDE) & secondary (SEC IDE)

A single IDE channel is now more typical if the MOBO supports SATA. Each IDE channel supports 2 devices, 0 & 1

121
Q

How many connectors does an EIDE cable typically have?

A

3 color-coded connectors

122
Q
