Electricity MUST flow in a complete circle to work at all; so most wiring is done in pairs.
Wire bundles are cables composed of many wires (or wire pairs) in a rope like bundle. They are usually not enclosed in a protective jacket.
There are 4 pairs, 8 wires in total.
There are four wire pairs. White/Blue - Blue, White/Orange - Orange, White/Green - Green, and White/Brown - Brown. Only two pairs are used in Cat5 networks.
4 pairs of wires.
In a standard LAN cross-connect, there are typically four pairs of wires in a cable, totaling eight individual wires. These pairs are usually twisted together to reduce electromagnetic interference and crosstalk. Common cable types used for this purpose include Category 5e, Category 6, and Category 6a cables. Each pair is used for data transmission in Ethernet networks.
4 pairs of wires, or 8 wires total
A Cat5 cable contains 4 pairs of 2 wires twisted together, making a total of 8 individual wires, however only 2 wire pairs (4 wires) are actually used for communication.

Twisted pairs
In an RJ-45 connector used for Ethernet networking, the active wires are typically the four twisted pairs of wires, totaling eight wires. For 10BASE-T and 100BASE-TX Ethernet, only two pairs (four wires) are used: pins 1 and 2 for transmit and pins 3 and 6 for receive. In 1000BASE-T (Gigabit Ethernet), all four pairs (eight wires) are utilized for simultaneous transmit and receive, allowing for higher data rates.
A category 6 cable contains 4 pairs of wires, for a total of 8. The pairs are twisted together along the length of the cable, which helps to reduce noise and preserve the signal.
Twisted pair cabling has 4 pairs of wires (8 wires in total), but 10BASE-T and 100BASE-TX requires only 2 of those pairs (4 wires in total).Exams will often try to trick you by asking questions like 10baseT uses how many pairs so you think you're being asked how many pairs does it have? When really you're just being asked how many pairs does it use.
