Cable most commonly used is a flat4 style, although any standard data cable can be used. Tools needed, MODULAR CRIMPING TOOL with RJ9 crimp port ( also known as a 4P?C plug) Common flat4 conductor colour and pin-out is. (pin 1 being the left-most as you look at the front of the connector with the locking clip upmost). 1- Black. 2- Red. 3- Green. 4-Yellow. Select RJ9 crimp connector to suit wire type (either solid or multi strand) this will ensure the best termination of the conductors. Carefully strip the outer insulation with either a sharp blade or the strippers as part of the modular crimper. Insert the RJ9 connector into the Modular crimping tool, followed by the cable, ( with inner insultation intact). Tighten the crimping tool, remove RJ9 connnector and inspect that the outer insulator in anchored by the rear cable crimp.
An RJ11 connector is a six-position two-conductor connector. An RJ9 connector is a term for a four-position, four-conductor connector that is often used to connect a handset to the base of a telephone.
RJ-45 or 8P8C modular connectors
RJ45 Modular connector can be bought at many different electronic stores in the neighborhood such as Radio Shack or Best Buy. Purchasing online can save you some money so be sure to check out ebay or amazon online stores.

It is on the back of your computer and a flash drive can fit in it.
Difference between modular and non-modular bricks
Your Ethernet cable should have an RJ-45 modular connector on each end of the cable. Connect one plug in the RJ-45 slot/connector in the back of the desktop unit, and connect the other end to a switch, hub, or router.
You use a Rj-45 connector with twisted-pair cabling in an Ethernet LAN. Rj-45 is a connector with a 4 5 wiring sequence.
additional ports can be added in modular routers.
