The link physically contains two wires. Which of the following is a possible option to allow both nodes to send data? b 6. UTP cables can have up to eight wires inside the cables. Which of the following is the most likely reason why EMI from one wire does not affect the electrical behavior of another wire inside the same cable?
Master It – The customer wants to ensure capability to operate 10Gbase-T What cable would you recommend to offer the best shielding performance? I would recommend the screened shielded twisted pair (f/FTP and S/FTP) Determine the uses of pleum-and-riser-rate cabling. Plenum cable – Cable whose flammable and smoke characteristics allow it to be routed in in air handling space between the wall, under structured floors, and above drop ceilings, without being enclosed in a concuit. Riser Cable- A type of cable to be used in vertical building shafts Such as telecommunications and utility
a. Broadband b. Modem c. ISDN d. DSL 8. To connect a LAN to the Internet, you must use __________. a. a hub b. a switch c. a router d. an Internet cable 9. Which TCP/IP protocol is specifically used for transferring
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.
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.
• Imagine you are a CISO of a publically traded company and concerned about security when sending any message traffic over the Internet to your remote sites. Determine the security measures you would consider implementing to mitigate security risks when sending message traffic over the Internet. Explain your reasoning. Teardrop – a mangled packet sent in fragments via overlapping or overloading payloads which could cause the systems as it has in the past with older OS versions. Sequence number – hijacked or interrupted TCP/IP sessions via injected packets that disguises its origination from one of the two computers in a session.
NT1210 Research Paper From what I gathered about “Layer 2 switches” is that the Layer 2 switches use a MAC address from a host NIC card. This makes it to decide where to “forward frames”. Also Layer 2 is a hardware-based control. It uses “application-specific integrated circuits”, which provides “wire speed, high speed, low latency”. 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.
DEMARC What is SONET WAN technology? One of several key technologies often found in a WAN. SONET - Synchronous Optical Network is an international standard for high speed communication over fiber-optic networks. The SONET establishes Optical Carrier (0C) levels from 51.8 Mbps to 10 Gbps (0C-192) or even higher. SONET provides high speed connectivity over the network and is standard for physical cable.

Lab 2.1: Connecting Computers Exercise 2.1.1 Media, Interface, Signal, Pattern, and Timing are all necessary to establish a network. Media is needed for the physical structure on which the signal will travel. Interface is needed so the computer can access the media. Signal is the means of transmission such as electrical signal. Pattern is the format for the signals to be interpreted.
