NT 1310 PHYSICAL NETWORKING UNIT 7 DEFINITIONS KENDAL JEFFERSON 1. CROSSTALK: The coupling or transfer of unwanted signals from one pair within a cable to another pair. Crosstalk can be measured at the same (near) end or far end with respect to the signal source. Crosstalk is considered noise or interference and is expressed in decibels. 2. WAVEGUIDES: A structure that guides electromagnetic waves along their length. The core fiber in an optical-fiber cable is an optical waveguide. 3. FTTH: :

NT 1310 NETWORK TOPOLOGY PAPER: KENDAL JEFFERSON Network topology refers to layout of a network and how different nodes in a network are connected to each other and how they communicate. Mesh Topology: in a mesh network‚ devices are connected with many redundant interconnections between network nodes‚ in a true mesh topology every node has a connection to every other node in the network. There are two types of mesh topologies: Full mesh occurs when every node has a circuit connection it to every

Ghattas The differences between LED and Laser Transmitters LED LED (Light-Emitting Diode) is a two-lead semiconductor light source. It resembles a basic p-n junction diode (is a boundary or interface between two types of semiconductor material‚ p-type and n-type‚ inside a single crystal of semiconductor.‚ which emits light when activated.

Windows NT is a unique and powerful operating system. It has been an entirely different operating system than Microsoft’s initial Windows desktops operating systems. It was simply better and more secure ("Survey of operating Systems" pg125.) Windows NT offers you a high degree of performance and a wealth of capabilities and features. ("Windows NT 101"‚ 1998.) NT supports two file systems: NtFS4 and FAT16. It can use up to 4 Gigabytes of RAM and also uses virtual memory. Windows NT doesn’t work well

Linux versus Windows NT Forget the browser wars. This year’s big nerd battle is the server shootout between Linux and Windows NT - and it’s not just a bunch of geeks nit-picking. While both offer more affordable platforms for Web service than in the past‚ Linux and NT are polar opposites on almost every other level. They look different‚ run differently‚ support different software‚ and cost money in different places. So far though‚ most press coverage of the Linux-NT debate has focused on the competing
