How do the following three types of LCD displays compare to each other?
TN
IPS
VA
TN: Fastest | Worst color and contrast ratios
IPS: In between | Best colors
VA: Slowest | Best contrast ratios
What two things must support a specified refresh rate (Hz)?
The GPU and monitor
Identify USB specifications, speeds and colors
Big gap happens at USB 3.0 and turns blue
What does a yellow USB port represent?
Always on
Capable of charging even when the PC is off
What additional features and speeds does USB4 support?
- 40 Gbps transfers
- DP support
- 4k displays
- Compatibility with Thunderbolt 3 & 4 devices
- Requires USB-C connector
Identify USB types
What two technologies does Thunderbolt combine?
PCIe and DisplayPort
What can Thunderbolt 4 (latest standard) support?
- DisplayPort 1.2 (first inroduced by TB 2)
- 40 Gbps speed (first introduced by TB 3)
- 10 Gbps Ethernet (first introduced by TB 3)
- Two 4k displays
- 32 Gbps PCIe
4 is 40Gbps
When did Thunderbolt switch from Mini DisplayPort to USB-C?
Thunderbolt 3
Also introduced 40Gbps speed
What is one benefit of copper cables over optical cables?
They can provide power to a device
Identify the connector
DB-9 serial
Used for RS-232 signals (standard of communication)
How many rows of pins does a VGA connector have?
3 rows
DB-9 has 2
What connectors utilize analog video?
VGA and DVI-A
Analog is electrical data. Digital is binary bata.
What DVI connector is this?
DVI-D
Identify the port
eSATAp (with power)
Can also utilize USB
Does an eSATA port provide power?
No.
Alternatively, a Power over SATA port combines eSATA and USB to supply power.
Identify the connector
PATA (formerly IDE)
Powered by a Molex connector
Identify the port
SCSI
Most often found on servers or enterprise systems
What is the most common audio connector?
TRS
2 ring 3.5mm cable (aux)
Which connector is compatible with DVI-A?
VGA
Summary of DVI Types
DVI-D: Digital signals only, directly compatible with HDMI for video. DVI-A: Analog signals only, similar to VGA. DVI-I: Both digital and analog signals, adaptable to either HDMI (digital) or VGA (analog).
What is the newer implementation of SCSI?
SAS (Serial Attached SCSI)
15,000 rpm HDs use this
Which USB standard had the biggest increase in data transfer speeds?
USB 3.0
The speed increased from 480 Mbps (USB 2.0) to 5 Gbps (USB 3.0). The color also turned to blue to differentiate the higher performance.
Which thunderbolt versions use mini DP?
Thunderbolt 1 and 2
What connector is the predecessor of USB?
Serial (DB-9)
Two rows of pins
