11. Cable Toner12. Continuity Tester- an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made 13. Category 5e/6 cable- is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards 14. Binder Groups- Cable pairs are typically arranged under the cable sheath in binder groups 15.
(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.)
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.
You can purchase the devices together as a single combination unit called an optical loss test set (OLTS) or as separate units in a fiber-optic test kit. The Time-Domain Reflectometers is the primary tool used to determine the length of a copper cable and to locate the impedance variations that are caused by opens, shorts, damaged cables, and interference with other systems. Two basic types of TDRs are available: those that display their results as a waveform on an LCD or CRT screen and those that use a numeric readout to indicate the distance to a source of impedance. You can use a TDR to test any kind of cable that uses metallic conductors, including the coaxial and twisted-pair cables used to construct LANs. A high-quality TDR can detect a large variety of cable faults, including open conductors; shorted conductors; loose connectors; sheath faults; water damage; crimped, cut, or smashed cables; and many other conditions.
SONET provides high speed connectivity over the network and is standard for physical cable. What is a byte? A byte is a series of 8 bits. When using a truth table, 1 and 0 equal? Equals 0 (Zero) What do parentheses do in mathematical equations?
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.
OIS layer 7 packets are called “layer 4-7 switches” these are like content switches, content service switches and web switches or application switches… Content switches are normally used for “load balancing” among server groups like on TCP/IP. Some can also do NAT wirespeed. Also they can be used in encryption and decryption to reduce the loading on servers. Layer 7 switching is the technology of “content delivery network”.. Layer 4 load balancer is a
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.
iii. Internet – Defines the protocols used for addressing and routing the data packets. iv. Network Interface – Defines how the host connects to the network. 2.
This link is above the Physical layer it is responsible for end-to-end validity of what is being transmitted. Datalink layer is divided into; two sub-layer which is Media Access Control (MAC) that determines the physical addressing of the host. The MAC addresses (physical device addresses) that communicate with other devices within the network. Then there is the Logical Link Control (LLC) sub layer. What it is responsible for is the synchronizing frames, error checking, and the flow control.
