2. Backbone Cable- Backbone cabling is cabling that supplies telecommunications access between different areas in a facility or complex 3. Patch Cords- is an electrical or optical cable used to connect ("patch-in") one electronic or optical device to another for signal routing. 4. Connectors- a thing that links two or more things together.
Voice or data computers, network interfaces, and transmission medium C. Modems, transmission links, and wireless access points D. TCP/IP software, modems, and transmission links Correct! The correct answer is: B. âA network consists of two or more connected computersâ (Laudon & Laudon, 2011, p. 194). âBasic network components include computers, network interfaces, a connection medium, network operating system software, and either a hub or a switchâ (p. 225). Networking and telecommunications technology, consisting of both physical devices and software, links the various pieces of hardware and transfers data from one physical location to another. 2.
I. (This layer is used to process requests from hosts and to make sure a connection is made to an appropriate port.) ii. Transport – Defines the type of connection established between hosts and how acknowledgements are sent. iii.
Andrey Borsch NT1310 Unit 4 Exercise 1 4-18-14 Cabling - Definitions Horizontal Cable - The cabling between and including the telecommunications outlet and the horizontal cross-connect. Horizontal cabling is considered the permanent portion of a link; may also be called horizontal wiring. Backbone Cable - The physical/electrical interconnections between telecommunications rooms and equipment rooms Patch Cord - Any flexible piece of cable that connects one network device to the main cable run or to a patch panel that in turn connects to the main cable run. Used for interconnecting circuits on a patch panel or cross-connect. Patch cables are short distance, usually have connectors preinstalled on both ends, are used to connect equipment, and are generally between 3 and 6 meters long.
(Choose two answers.) a,c 3. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. Which of the following tasks is a function done by the transmitter? (Choose two answers.)
OSI Model: Open System Interconnection * Is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into abstraction layers 7) Application Layer | 6) Presentation Layer | 5) Session Layer | 4) Transport Layer | 3) Network Layer | 2) Data Link Layer | 1) Physical Layer | * The model group’s communication functions into seven logical layers. A layer serves the layer above it and is served by the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer. (Wikipedia) 2.
They are usually located in a LAN like a home or on the internet. Lab 2.1 Review 1. A network device is equipment used to connect two or more computers together, such as a router, network cable, and network cards. A peripheral device is any external device on a computer such as a mouse, keyboard, or a monitor. 2.
1. Which of the following are required when adding a network to the OSPF routing process configuration? network address wildcard mask area ID 2. Which of the following are primary functions of a router? (Choose two.)
What it is responsible for is the synchronizing frames, error checking, and the flow control. The third layer of the seven layers of (OSI) network model is the Network layer. The responsibility of the Network layer is managing the logical address information in packets and the delivery. The responsibility in managing logical addressing information and make sure that it is correctly sent to the right destination. The direct data packet generated by Network Layer using information that is stored in a table known as routing table.
Master It 1. What is the most typical implementation of the hierarchical star? Specifically, where are the horizontal cross-connection and workgroup switches typically placed? 2. To reduce the cost of a hierarchical star, the network designer has the option to locate network elements closer to equipment outlets.
