LOCAL AREA NETWORK TECHNOLOGY
Local area network technology is the technology used to make local area network to
support data communication by connecting terminals, computers and printers within a small
limited geographical area. Examples of LAN Technology include; Token Ring, Fibre
Distributed Data Interface (FDDI) and ARCNET.
Local Area Network is a data communication network connecting Terminals, Computers
and Printers within a building or other geographically limited area. These devices can be
connected through wired cables or wireless link.
It is also a communication network for computers within a building or small group of
buildings. It may be configured as;
1. A bus, a main channel to which nodes or secondary channels are connected in a branching
structure.
2. A ring in which each computer is connected to two neighbouring computers to form a
closed circuit.
3. A star in which each computer is linked directly to a central computer and indirectly to one
another.
Each of these has an advantage though a bus configuration has become the most.

ETHERNET
Ethernet is a standard communications protocol embedded in software and hardware
devices, intended for building a local area network (LAN). It was designed by Bob Metcalfe
in 1973, and through the efforts of Digital, Intel and Xerox (for which Metcalfe worked),
"DIX" Ethernet became the standard model for LANs worldwide
EVOLUTOIN OF ETHERNET
Ethernet evolved to include higher bandwidth, improved media access control (MAC)
method and different physical media. The coaxial cable was replaced with point-to-point
links connected by Ethernet, repeaters or switches to reduce installation cost, increasing
reliability and improve management and troubleshooting. Many variants of Ethernet remain
in common use.
Ethernet stations communicate by sending each other data packets; blocks of data…...

Often they are in different structures. Congress is not consistent. Example - U.S. Postal Service - Federal Corporation set up by the government for profit. Rates are reviewed by the postal rate commission. When addressing legal issues, the one question you ask is what does this issue sound in? Contract, property, tort ? One problem with admin law is trying to figure out whose rules to follow. Power of the president to control/fire people. At the cabinet level, no problem. Lower level positions usually are insulated by statute that says “for cause” . . . 1. Presidential Power ‘the Unitary President’ F&S 51-67 Vesting Clause: Art. II §1; Take Care Clause: Art. III, §3 Meyers and Humphreys focus on two kinds of issues: (1) separation of powers, (2) non-delegation: Separation of powers is an issue of encroachment - if congress can fire people under the executive branch, they step on the presidents toes. Isn’t it the same type of encroachment if congress says the president can not fire the head of an agency?

...The Department of Housing and Urban Development Abstract The Department of Housing and Urban Development has developed programs designed to help out the less fortunate for years and protect them from discrimination. Administrative law is especially valuable to agencies such The Department of Housing and Urban Development as it addresses fairness and responsibility issues with governing laws.

Admin Distance & Junos Route Preferences

...NT2640 Cisco IOS Admin Distances & Juniper JUNOS Route Preferences Introduction Most routing protocols have metric structures and algorithms that are not compatible with other protocols. In a network with multiple routing protocols, the exchange of route information and the capability to select the best path across the multiple protocols are critical. Administrative distance is the feature that routers use in order to select the best path when there are two or more different routes to the same destination from two different routing protocols. Administrative distance defines the reliability of a routing protocol. Each routing protocol is prioritized in order of most to least reliable (believable) with the help of an administrative distance value. Prerequisites Requirements Cisco recommends that you have knowledge of these topics: * Basics of the routing process. Refer to Routing Basics. Components Used This document is not restricted to specific software and hardware versions. Conventions Refer to Cisco Technical Tips Conventions for more information on document conventions. Select the Best Path Administrative distance is the first criterion that a router uses to determine which routing protocol to use if two protocols provide route information for the same destination. Administrative distance is a measure of the trustworthiness of the source of the routing information. Administrative distance has only local significance, and is not advertised in routing...

... administrative decisions apply rules of that kind to particular cases; - 2. parliamentary control of the relevant decision, although not definitive, is an indication that the decisions might properly be characterised as legislative rather then administrative. - 3. A requirement of public consultation further indicates the decision may be one of a legislative rather than administrative nature; - 4. The fact that provision is made for review of decision on the merits is an indication that the decision is of an administrative nature. - 5. The fact that a decision has a binding legal effect, in the sense of directly affecting the operation of other statutory provisions suggests it is legislative in nature. Paradise v GCCC decision of legislative character as it is a by-law, admin character applies by-law rule to a fact situation to achieve a result.

...The Globe Samsung’s unlikely success in mixing Western best practices with an essentially Japanese business system holds powerful lessons for today’s emerging giants. by Tarun Khanna, Jaeyong Song, and Kyungmook Lee A s today’s emerging giants face the challenge of moving beyond their home markets, they have much to learn from the pathbreaking experience of South Korea’s Samsung Group, arguably the most successful globalizer of the previous generation. Twenty years ago, few people would have predicted that Samsung could transform itself from a low-cost original equipment manufacturer to a world leader in R&D, marketing, and design, with a brand more valuable than Pepsi, Nike, or American Express. Fewer still would have predicted the success of the path it has taken. For two decades now, Samsung has been grafting Western business practices onto its essentially Japanese system, combining its traditional low-cost manufacturing prowess with an ability to bring high-quality, high-margin branded products swiftly to market. The two sets of business practices could not have seemed more incompatible. Into an organization focused on continuous process improvement, Samsung introduced a focus on innovation. Into a homogeneous workforce, Samsung introduced outsiders who could not speak the language and were unfamiliar with the company’s culture. Into a Confucian tradition of reverence for elders, Samsung introduced merit pay and promotion, putting...

...This situation usually arises in one of two circumstances: * A company has a small amount of remaining unused production capacity available that it wishes to use; or * A company is unable to sell at a higher price The first scenario is one in which a company is more likely to be financially healthy - it simply wishes to maximize its profitability with a few more unit sales. The second scenario is one of desperation, where a company can achieve sales by no other means. In either case, the sales are intended to be on an incremental basis; they are not intended to be a long-term pricing strategy, since prices set this low cannot be expected to offset the fixed costs of a business. The variable cost of a product is usually only the direct materials required to build it. Direct labor is rarely completely variable, since a minimum number of people are required to crew a production line, irrespective of the number of units produced. The Marginal Cost Calculation ABC International has designed a product that contains $5.00 of variable expenses and $3.50 of allocated overhead expenses. ABC has sold all possible units at its normal price point of $10.00, and still has residual production capacity available. A customer offers to buy 6,000 units at the company's best price. To obtain the sale, the sales manager sets the price of $6.00, which will generate an incremental profit of $1.00 on each unit sold, or $6,000 in total. The sales manager ignores the allocated overhead of...
