Solutions
S1. Ans.(b)
Sol. Broadcast network are characterized by the presence of a single communication channel that is shared by all users. Messages, in some cases called packets, are sent by each user and received by all the others.
S2. Ans. (d)
S3. Ans. (d)
Sol. Fiber optic cables transmit signals in the form of optical signals over a narrow glass fiber stand.
S4. Ans.(d)
Sol. There are two types of twisted pair cables are Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP). Unshielded Twisted Pair (UTP) cables.
S5. Ans. (a)
Sol. Short for unshielded twisted pair, a popular type of cable that consists of two unshielded wires twisted around each other. Due to its low cost, UTP cabling is used extensively for local-area networks (LANs) and telephone connections.
S6. Ans. (a)
Sol. Twisted pair wires are used in telephone networks and for digital data transmission over short distances up to 1 km.
S7. Ans. (d)
Sol. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
S8. Ans.(d)
S9. Ans. (d)
Sol. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
S10. Ans. (d)
Sol. optical fiber, co-axial cable and twisted pair wire are example of guided medium. Micro waves are unguided medium.
