Cable Types and Connectors

Question 1

HDMI

Answer 1

Is currently the most popular Audio/Video interface for both consumer electronics and computer systems.

Question 2

DisplayPort

Answer 2

Audio/video interface developed by VESA as royalty free alternative to HDMI. Shares some compatibility with DVI and HDMI.

Question 3

Thunderbolt

Answer 3

Is both a Audio/Video interface like HDMI and a general peripheral interface like USB 3. The current version uses USB-C connectors.

Question 4

Lightning

Answer 4

Propitiatory connector and interface for apple iphone and ipad devices.

Question 5

SATA

Answer 5

serial ATA is the most common connector for internal storage devices found in laptops and desktops. It uses a 7 pin data connector and is powered by a 15 pin power connector or the older MOLEX power connector.
SATA 3 can transfer 6Gbps (600MBps).

Question 6

Molex Connector

Answer 6

Legacy power connector for internal devices.

Question 7

eSATA

Answer 7

external SATA is a variant of SATA cabling for external use such as external HDD.

Question 8

A technician connects a single port on a graphics card to two monitors using two cables, what kind of interface is being used?

Answer 8

Thunderbolt or DisplayPort, using daisy chaining.

Question 9

USB-C ports are compatible with apple lightning connectors and ports?

Answer 9

No, you would need an adapter.

Question 10

Should a blanking plate be used after removing a expansion card?

Answer 10

Yes, the airflow will be affected and dust will accumulate in the system.

Question 11

what is the connector in image

Answer 11

USB-2.0 type B micro.

Question 12

What is the connector in the image?

Answer 12

Legacy Molex power connector.

Question 13

The system case/chassis

Answer 13

houses the internal components. These include the motherboard, central processing unit (CPU), system memory modules, adapter cards, fixed disks, and power supply unit.

Question 14

Blanking plates?

Answer 14

A blanking plate is a flat, solid piece of material used to cover and seal off unused openings or ports. Blanking plates are necessary to prevent gaps in the system case. Gaps create the following problems:
-Dust
-ESD
-EMI

Question 15

ESD

Answer 15

electrostatic discharge (ESD) means that a static charge on someone’s finger or on a tool is conducted into a computer chip. This can cause a temporary or permanent fault in the chip.

Question 16

EMI

Answer 16

electromagnetic interference (EMI). EMI is energy from magnetic and electrical sources, such as motors or other electronic devices and radios, that can cause temporary or permanent faults. The PC’s case absorbs this energy, but gaps can reduce this protection.

Question 17

Port

Answer 17

A hardware port is the external connection point for a particular type of bus interface. A bus allows the transfer of data to and from devices.

Question 18

Connector

Answer 18

The connector is the part of a peripheral cable that can be inserted into a port with the same shape or form factor. Each bus interface type might use multiple connector form factors. Most connectors and ports now use edge contacts and either have an asymmetric design called keying to prevent them from being inserted the wrong way around or are reversible.

Question 19

Universal Serial Bus

Answer 19

The Universal Serial Bus (USB) is the standard means of connecting most types of peripheral devices to a computer. A USB is managed by a host controller.

Question 20

USB 2.0

Answer 20

The USB 2.0 HighSpeed standard specifies a data rate of 480 Mbps shared between all devices attached to the same host controller. The bus is half-duplex, meaning that each device can send or receive, but not at the same time.

Question 21

USB 3.x

Answer 21

Iterations of USB 3.x introduced new connector form factors and upgraded transfer rates, each of which are full-duplex, so a device can send and receive simultaneously.
USB 3.2 Gen 1 SuperSpeed USB
5 Gbps
USB-A, USB-B, USB-C, USB Micro

USB 3.2 Gen 2x1 SuperSpeed USB
10 Gbps
USB-A, USB-C, USB Micro

USB 3.2 Gen 2x2 SuperSpeed USB
2 x 10 Gbps
USB-C

Question 22

USB Cable Length

Answer 22

The maximum cable length for LowSpeed devices is 3 meters.
FullSpeed and HighSpeed the limit is 5 meters.
SuperSpeed-capable cables do not have an official maximum length, up to about 3 meters is recommended.

Question 23

USB Power

Answer 23

As well as a data signal, the bus can supply power to the connected device. Most USB Type A and Type C ports can be used to charge the battery in a connected device.
Basic USB ports can supply up to about 4.5 watts, depending on the version.
