Describe the different types of connector used in LAN?

UTP - Unshielded Twisted Pair

STP - Shielded Twisted Pair

MMF - Multi-Mode Fiber

SMF - Single Mode fiber

Connectors

With all the different types of cabling come a number of different cable connectors. 

I have listed below the different type of connectors for your reference 

Registered Jack 45 (RJ45)

The cable connector that is found on almost all UTP and STP cables is a Registered Jack 45 which is mostly commonly referred to as RJ45. This type of connector resembles the older RJ11 connectors that most people are familiar with from wired telephones.

Straight Tip (ST)

The Straight Tip (ST) connector is often seen on the end of a multi-mode cable; it has been commonly seen along with the SC connector for the last 20 years but is being slowly replaced by multi-fiber connectors (LC and MTP). 

Subscriber Connector (SC)

The Subscriber Connector (SC) can be seen commonly on MMF or SMF; as with SC connectors, the ST connector is slowly being replaced by multi-fiber connectors. 

Lucent Connector (LC)

The Lucent Connector (LC) was developed for high-density deployments where multiple fibers would be terminated within a confined space. Unlike the SC and ST connectors, the LC connector is always duplex connecting a pair of fibers at a time. 

Multi-fiber Push On (MPO)

The Multi-fiber Push On (MPO) connector is another duplex connector that offers an easy options for connection. As the name suggests, it was designed to be able to be connected multiple times without the creation of any potential connector issues. It is often also referred to as Multi-fiber Termination Push-on (MTP); the MTP connector is a brand name (US Conec). 

Summary

It does seem very basic, but knowing the different cable and connector types is an important part of being a network engineer/administrator. 

The answer by Mr Balagee is the best answer from the Pearson website from this link

And yes different types of cables have different connectors as listed in the link above

The answer provided by Mr Jahbar represents the cable types (twisted pair and Fibre optics) and not connectors, thus, it is not correct answer
