Answer 1

C
Explanation: UTP cable types vary in their data carrying capacity. Common categories of UTP cabling include the following: Category 3 (Cat 3 ) cable is commonly used in Ethernet 10BASE-T networks, which carry data at a rate of 10 Mbps (where Mbps stands for megabits per second, meaning millions of bits per second). However, Cat 3 cable can carry data at a maximum rate of 16 Mbps, as seen in some Token Ring networks. Category 5 (Cat 5 ) cable is commonly used in Ethernet 100BASE-TX networks, which carry data at a rate of 100 Mbps. However, Cat 5 cable can carry ATM traffic at a rate of 155 Mbps. Most Cat 5 cables consist of four pairs of 24 gauge wires. Each pair is twisted, with a different number of twists per meter. However, on average, one pair of wires has a twist every 5 cm. Category 5e (Cat 5e) cable is an updated version of Cat 5 and is commonly used for 1000BASE-T networks, which carry data at a rate of 1 Gbps. Cat 5e cable offers reduced crosstalk, as compared to Cat 5 cable. Like Cat 5e cable, Category 6 (Cat 6 ) cable is commonly used for 1000BASE-T Ethernet networks. Some Cat 6 cable is made of thicker conductors (for example, 22 gauge or 23 gauge wire), although some Cat 6 cable is made from the same 24-gauge wire used by Cat 5 and Cat 5e. Cat 6 cable has thicker insulation and offers reduced crosstalk, as compared with Cat 5e. Category 6a (Cat 6a), or augmented Cat 6 , supports twice as many frequencies as Cat 6 and can be used for 10GBASE-T networks, which can transmit data at a rate of 10 billion bits per second (10 Gbps).
