Practice Activity 2: Cabling – Definitions

...PRACTICE Activity 2: Cabling – Definitions In-Class Activity, Graded Description: The goal of this activity is to learn the basic terminology used in copper and fiber cabling. It builds a strong foundation and allows everyone to speak the same language when discussing topics in this course. Give students a few minutes to review the chapters, looking for key terms. Divide the class into two teams. Read the definition and have the teams race to the board to write the correct term. At the end of the game, go over each term again. Then, have students write down each term and define it. Please define the following terms: Horizontal Cable- cable which supports a single floor of a building Backbone Cable- high traffic cable which frequently connects multiple floors, buildings, or continents Patch Cords- short, manufactured cables offered in various lengths and colors for patching from permanent cable installations to workstations or switch points Connectors- the things copper wires go into that allows them to connect to jacks Conduit- the tubes that house and protect cables Racks- a fixture for mounting various hardware components, providing ease of access, better ventilation, and more flexibility than cases Punch-Down Blocks- connection bits which cut the insulation of copper wires and forces the copper itself into contact with a circuit. Special tool required. Consolidation Points- a convergence point for the horizontal cabling of a section or......

LAN Domain The Local Area Network Domain is a group of computers that are all connected to a single LAN domain. The LAN Domain is a collection of computers connected to each another or to a common medium. All LAN domains have data closets, physical elements of the LAN, and logical elements as designated by authorized personnel. It involves strong security and access controls. This domain can access company-wide systems, applications, and data from anyplace within the LAN. The LAN support group is in control of maintaining and securing the domain. The biggest threat to the LAN domain is an Un-authorized access to anything on the network. For example: LAN, the systems, and data. One thing we can do is require strict security protocols for this domain, such as disabling all external access ports for the workstation. This would cause a no......

Unit 5 Cabling Factors

...4/14/2014 Unit 5. Assignment 1: Cabling Factors and Tools Discussion Three factors that need to be considered is being fire protected, water proof, and shock protection. Being fire protected, just in case a fire occurs, the wiring would be protected by a casing around the actual wires which in cause wouldn’t melt the casing and destroy the wires. Since the data room is usually in the basement of companies, if a flood occurs, there are wires that are protected by a casing that would not let water intrude into the casing. For shock protection, there is always a chance for a shortage to happen. Wiring and a lot of electricity used. For example, if there is a storm going on and lightning hits a generator and shorts everything out, it would not fry the wiring if they are protected from the shock. The two most important considerations to take into account when either pre-wiring a house or wiring after the house is complete, are the routing of the cable and the quality of the wire used. These two points are often overlooked and the decision to wire the house at all often comes as an afterthought, when most if not all of the interior of the structure has been completed. Some tools that would be useful to use are cable cutters, hole cutting tools, wire strippers, punch down tools, RJ45 connector crimp kits, pliers and cutters, label makers and electrical tape. The makeshift tool that we would use is a staple gun....

Unit 5 P2 Definitions

...P2 - Definitions Capital Income: This is the net worth of a business. It’s the amount in which assets exceed liabilities. It’s the income that comes from capital, which means it’s coming directly from the government itself, rather than any specific production or direct work. Capital income includes stock dividends or any sort of capital gains, as well as income an owner gets from a business they own. Sole traders: If you’re self-employed then it means you work for yourself, and not for an employer. A sole-trader is a self-employed person and they are the sole owner of their business. Partners: Partners are people who have shares within businesses. This means they don’t solely own the business; it could be split by 2 or more people, starting with a 50% share for 2 people and so on. Shares: If someone has a share within a business, it means that they have a unit of ownership within a corporation or financial asset. However, owning shares of a business doesn’t generally mean that they have direct control over said business on a day to day basis, but they are entitled to an equal distribution of any profits if any end up being declared in the form of dividends. Loans: A loan is something that is borrowed, generally money. This means people borrow a sum of money (often a large sum of money) and they’re expected to pay it back, with interest. Mortgages: A mortgage is a legal agreement between somewhere like a bank or building society, and they lend money in agreement that...

Cabling Design, Standards, Codes and Definitions

...Cabling Design, Standards, Codes and Definitions The American National Standards Institute (ANSI) is a non-profit organization whose membership is made up of over 1,400 private companies and government organizations. ANSI facilitates the development of national standards by accrediting the procedures of the organizations that develop the standards. In order to gain ANSI approval, the document must be developed by a cross-section of both manufacturers and end users. ANSI is also a founding member of the ISO. The International Organization for Standardization (ISO) is an organization of many national specifications bodies from over 160 countries and is based in Geneva, Switzerland. The ISO standards are developed by the people that need them, through a consensus process. They ensure that products and services are safe, reliable and of good quality (ISO Org., 2015). Each ISO member is the principal standards organization in its country. The members propose the new standards, participate in their development and provide support in collaboration with ISO Central Secretariat for nearly 3.280 technical groups that actually develop the standards. The Electronic Industries Alliance (EIA) represents a wide variety of electronics manufacturers in the United States and abroad. It was developed to ensure the equipment of different manufacturers was compatible and interchangeable. In 2007, the EIA announced that it would be dissolved and formally ceased to exist on February 11,......

...APPLICATION (IN TERMS OF CABLING INFRASTRUCTURE)- (1) A program running on a computer. (2) A system, the transmission method of which is supported by telecommunications cabling, such as 100Base-TX Ethernet, or digital voice UNSHIELDED TWISTED-PAIR- (1) A pair of copper wires twisted together with no electromagnetic shielding around them. (2) A cable containing multiple pairs of UTP wire. Each wire pair is twisted many times per foot (higher grade UTP cable can have more than 20 twists per foot). The twists serve to cancel out electromagnetic interference that the transmission of electrical signal through the pairs generates. An unshielded jacket made of some type of plastic then surrounds the individual twisted pairs. Twisted-pair cabling includes no shielding. UTP most often refers to the 100 ohm Categories 3, 5e, and 6 cables specified in the ANSI/TIA/EIA-568-B standard SHIELDED TWISTED-PAIR- A type of twisted-pair cable in which the pairs are enclosed in an outer braided shield, although individual pairs may also be shielded. STP most often refers to the 150 ohm IBM Type 1, 2, 6, 8, and 9 cables used with Token Ring networks. Unlike UTP cabling, the pairs in STP cable have an individual shield, and the individual shielded cables are wrapped in an overall shield. The primary advantages of STP cable are that it has less attenuation at higher frequencies and is less susceptible to EMI. Since the advent of standards-based structured wiring, STP cable is rarely used in the......
