2. RJ11 AND RJ45 CABLE:
RJ is the acronym for Registered Jack
The main difference between these two is in where they are actually used. RJ45 jacks
are used in networking (Ethernet LAN), where you connect computers or other network elements
to each other. RJ11 is the cable connector that is being used in telephone sets.

3. VGA:
VGA stands for Video Graphics Array. At its core, VGA is an analog interface
standard for computer video output. It defines both a display hardware specification and a 15-pin
connector type used to connect video sources (like computers) to display devices (like monitors).

4. HDMI:
What is the full form of HDMI?
The full form of HDMI is the High Definition Multimedia Interface. It is an all-digital audio-
video interface that transmits information to a computer monitor, video projector, digital
television and so on, in uncompressed mode. For example, uncompressed video information
and compressed or uncompressed digital information from an HDMI-authorized source unit.
Different types of HDMI
Various types of HDMI cables are available.
Standard cable
It is often referred to as the HDMI cable Category 1. It functions at 75 MHz pixel rates,
enabling a bandwidth of around 2.23 GBps. It is ideal for sending a 1080i signal that is
uncompressed.
High-speed cable
It is often referred to as the HDMI Level 2 cable. It functions at 340 MHz pixel rates, enabling
a bandwidth of around 10.2 GBps. For the recent 1440p & WQXGA resolutions, it is suitable.

7. Ethernet Cable Color Coding:
Ethernet cable which is used to connect networking devices through UTP(Unshielded
twisted pair) cable and end is terminated with RJ45 connector. In UTP cable consist of 4pair or
8 wire of different color that is used to terminate on RJ45 connector. Ethernet cable color coding
as standardized by EIA(Electronic Industries association) and TIA(Telecommunication Industry
Association) there are two standard EIA/TIA-568-A and EIA/TIA-568-B.
EIA/TIA-568-A
In EIA/TIA-568-A the eight wire are arranged in Green-White, Green, Orange-White,
Blue, Blue-White, Orange, Brown-White, Brown.

8. EIA/TIA-568-B
In EIA/TIA-568-B the eight wire are arranged in Orange-White, Orange,
Green-White, Blue, Blue-White, Green, Brown-White, Brown.

9. An easy way to remember color code is in odd places(1,3,5,7) color with white strip
are present. Two types of Ethernet cable connection are made using EIA/TIA-568-A and
EIA/TIA-568-B standard
Straight-Through cables
Crossover Ethernet cable
Straight-Through cables:
In Straight-Through cable both the end is terminated with the same standard i.e.
EIA/TIA-568-A or EIA/TIA-568-B standard Any of one use at both ends of the cable.
Nowadays most patch cable are terminated with T568-B standard.

11. Straight cable are used to connect MDI and MDX devices. Straight Cable is
used to connect two dissimilar devices MDI and MDIX.
MDI– Medium Dependent Interface type of Ethernet port found on network devices, device
like end station, Ethernet card that inside our computer or laptop.
MDIX(or MDI-X) – Medium Dependent Interface Crossover is similar to MDI, but
interchange the transmit and receive pins within the interface. Device are generally
infrastructure equipment like router, Switch or firewall etc
In straight through 10Base-T and 100Base-T four wire (Two Pair) of UTP cable is used and in
1000Base-T all the eight wire (Four Pair) are used.

13. Crossover Ethernet cables
In crossover Ethernet cable both the end is terminated with different standard i.e.
EIA/TIA-568-A and EIA/TIA-568-B standard.

14. Ethernet Cross-Over Cables used to connect MDI to MDI and MDI-X to MDI-X.
Cross Over cable is used to connect two similar devices.
In Crossover Cable 10Base-T and 100Base-T four wire (Two Pair) of UTP cable are used
and in 1000Base-T all the eight wire (Four Pair) are used.
* 10/100/1000 ethernet - we get 10 Megabits, 100 Megabits, and 1000 Megabits.
