If you needed to convert between digital and analog video, which adapter would be required?
DVI - VGA
_ is used in plenum spaces (a space between the actual ceiling and a drop ceiling)
Plenum cabling
_ balance pair operation which means that are differential signaling
Twisted pair cable
_ is equal but opposite signals travel on each pair member and examining the difference between each member allows for the receiver to determine what is noise and cancel it
Twisted pair cable
_ is when twisted pairs of wires are less susceptible to interference
Less cross talk
transmits data by using pulses of light Transmission over great distances Highly secure data transmission Not affected by electrical or radio interference Cables are generally very robust
Fiber optic cabling
RG-6 and RG-59 are both
coaxial cables
_ are commonly used by cable companies for your internet service and suitable for longer distances and higher bandwidth
RG-6
_ are suitable for shorter distances and lower bandwidth and it is more commonly used as patch cables
RG-59
the benefits of _ are
You can divide it up into frequency ranges (this is why you can get many channels on your TV over the same single cable)
Lower error rates than twisted cable
High capacity in terms of its bandwidth
Rigid design (makes it pretty robust and its not very prone to breaks)
coaxial cable
100BASE-TX can travel a distance of _ meters
100
_ fiber cable is for shorter distances. Its cheaper and used in data centers
multimode
_ fiber cable is for longer distances. It is used to connect data centers that are far apart. It is more expensive
single mode
_ cable is
Unshielded cable
Speed of 10 or 100 Mbps
Operate at a frequency of about 100 MHz
Cat5
_ cable is
Unshielded
Speed of 1000 Mbps/1 Gbps
Operate at a frequency of about 100 MHz
Cat5e
The main differences between _ and _ are quality control. There are more stringent regulations on the testing and manufacturing of 5e.
Cat5 and Cat5e
Key features of _
Shielded or unshielded
1000 Mbps/1 Gbps
>250 MHz
Cat6
Key features of _
shielded
10000 Mbps/10 Gbps
500 MHz
Cat6a
this video cable is _
Has 15 pins in three rows of five
Physical connector is usually blue
Analog signal (it uses variances in electrical impulses to represent variances in colors, primarily red, green, and blue) sometimes referred to as and RGB connection
The longer the cable is the more degraded the signal could become
VGA
DVI - I (single link) operates at _ gigabits per second per second 60 frames per second
3.7
Dual link operates at _ gigabits per second at 85 frames per second
7.4
DVI-I supports _ signals
analog
DVI-D supports _ signals only
digital
_ is integrated and supports both analog and digital signals
DVI-I
_ allows you to connect video sources to your display
carries audio as well
DisplayPort
_ is a specification defined by the Video Electronics Standards Association (VESA)
-Means its not proprietary, manufacturers don’t have to pay a licensing fee to put a display port on their device
Packetized data transmission
Compatible with DVI and HDMI
DisplayPort
_ is a digital video audio interface
replaces analog standards
HDMI
_ cables are proprietary cable Brand name (Intel and Apple)
- Transmits data and power
- Uses a combination of PCI Express and DisplayPort over two separate serial channels to allow for peripheral device connections in configurations that can be daisy change for up to six devices
Thunderbolt
USB
Universal Serial Bus
USB _ was introduced in 1996 as version 1.0
At that time there were two variations
- Slow speed that operated at 1.5 Mbps over a distance of 3 meters
- Full speed that operated at 12 Mbps over a distance of 5 meters
Physical connectors
- Had type A that connected to computer
- Had type B that connected to device
1.0
USB _ was released in 2000 Introduced modifications to USB package Speed was increased to 480 Mbps over 5 meters Connectors • Type-A • Mini A • Micro A • Type-B • Mini B • Micro B
2.0
USB _ was released in 2008 Operated at SuperSpeed with operated at 5 Gbps over 3 meters Implemented full duplex communication Connectors • Type-A • Type-B • Micro B Superspeed
3.0
USB _ has a 24 pin USB connector USB 3.1 • SuperSpeed transfer mode (5 Gbps) • SuperSpeed+ transfer mode USB 3.2 • Two new SuperSpeed+ transfer modes • 10 and 20 Gbps throughput
C
_ cables are transfer data between devices using Serial communication protocol -That transmits data one bit at a time Primarily used -For lower bandwidth devices over long distances Communication standards -Varying transmission standards
Peripheral
An example of serial communication is _ serial communication
RS-232
_ Serial communication is
communication between Data Terminal Equipment (such as a computer terminal) and Data Circuit-Terminating Equipment (a device such as a modem)
RS-232
_ standard defines
Signal characteristics from electrical standpoint like the timing and meaning of the signals
Physical characteristics like the pin out configuration of the cables
RS-232
