1. Multi-point is a line or circuit interconnecting several stations/nodes in a sequential fashion.

Point-to-point is a circuit or line that has only two terminals

2. Guided media are the physical links through which signals are confined to narrow path. Three common types of bounded media are used of the data transmission. These are Coaxial Cable, Twisted Pairs Cable, and Fiber Optics Cable. Twisted pair

A pair of wires used in standard telephone wiring. They are twisted to reduce interference caused by the other twisted pairs in the same cable bundle. Twisted-pair wires go from homes and offices to the telephone company end office.

Fiber-optic cable

A transmission medium that uses glass or plastic cable instead of copper wires.

Coaxial cable

An insulated wire that runs through the middle of a cable. A second braided wire surrounds the insulation of the inner wire like a sheath. Used on LANs for transmitting messages between devices.

6.

Analog Transmission

Transmission of a continuously variable signal as opposed to a discrete on/off signal. The traditional way of transmitting a telephone or voice signal is analog.

Digital transmission

Is the transmission of binary electrical or light pulses in that it only has two possible states, a 1 or a 0. The most commonly encountered voltage levels range from a low of +3/−3 to a high of +24/−24 volts. Digital signals are usually sent over wire of no more than a few thousand feet in

Mis 589 Week 2 Homework

...Week 2 Homework assignment R3) What are some of the possible service that a link-layer protocol can offer to the network layer? Which of these link layer services have corresponding services in IP? In TCP? Some of the possible services that can be offered by a link-layer protocol include Framing which encapsulates each network-layer datagram within a link layer frame prior to transmitting. Link access, Reliable delivery and Error detection and correction are the remaining services offered by a link-layer protocol. Reliable delivery has a corresponding service in TCP. Link access has corresponding services in IP. Suppose two nodes start to transmit at the same time a packet of length L over a broadcast channel of Rate R. Denote the propagation delay between the two nodes as dprop. Will there be a collision if dprop <L/R? Why or Why not. Since both nodes are transmitting at the same time, I assume Dprop would be N1/N2 =1. The efficiency is 1/ (1+ 5(1)/ dtrans. The test states that as Dprop approaches 0, the efficiency approaches 1 and vice versa. So, since dprop is 1 the efficiency is towards 0 which would suggest a collision. How big is the MAC address space? The IPv4 address space? The IPv6 address space The MAC address space is 6 bytes long or 2*48 possible MAC addresses. 281474976710656 possible MAC addresses. MAC addresses are managed by the IEEE assuring no two adapters have duplicate addresses. The addresses are normally in Hexadecimal format. The...

...Jackson, insisted he had to plow his fields before he could write, and Joseph Conrad, author of Lord Jim and other novels, is said to have cried on occasion from the sheer dread of sitting down to compose his stories. To spare you as much hand-wringing as possible, this chapter presents some practical suggestions on how to begin writing your short essay. Although all writers must find the methods that work best for them, you may find some of the following ideas helpful. But no matter how you actually begin putting words on paper, it is absolutely essential to maintain two basic ideas concerning your writing task. Before you write a single sentence, you should always remind yourself that 1. You have some valuable ideas to tell your reader, and 2. More than anything, you want to communicate those ideas to your reader. These reminders may seem obvious to you, but without a solid commitment to your own opinions as well as to your reader, your prose will be lifeless and boring. If you don’t care about your subject, you can’t very well expect anyone else to. Have confidence that your ideas are worthwhile and that your reader genuinely...
