(A)Twisted Pair

Advantages :

1. Cheaper and far easier to splice.

2. Less susceptible to electrical interference caused by nearby equipment or wires.

3. In turn are less likely to cause interference themselves

.4. Because it is electrically "cleaner", STP wire can carry data at a faster speed.

Disadvantages :

1. STP wire is that it is physically larger and more expensive than twisted pairwire.

2. STP is more difficult to connect to a terminating block.

(B)Coaxial Pair

Advantages :

1. Coaxial cable can support greater cable lengths between network devices than twisted pair cable.

2. Thick coaxial cable has an extra protective plastic cover that help keep moistureaway.

Disadvantages :

1. Thick coaxial is that it does not bend easily and is difficult to install.

(C)Fiber Optic

Advantages :

1. One single mode fiber can replace a metal of time larger and heavier.

2. Multi-mode optical cable has a larger diameter and can be used to carry signalover short distance.

Disadvantages :

1. Fiber optic versus metal cable is that it is difficult to make connections tofiber optic cable.

2. The optical fiber must be highly polished to allow light to pass with little loss.

B2B (Business-to-Business)

E-Commerce is conducted through industry-sponsored marketplaces and through private exchanges set up by large companies for their suppliers and customers. Of course, companies also sell to business customers through their own Web sites. In the early 2000s, industry-sponsored marketplaces (ISMs) accounted for only a small percentage of B2B transactions. The main reason, according a survey of 25 ISMs published in the industry periodical B to B, is that ISMs have had problems convincing buyers and sellers to use them. For one thing, companies are reluctant to acquire customized designs through marketplaces because they don't want to reveal proprietary information on an site that is shared by competitors. These companies fear they will give away too much information about their competitive strategies simply by taking part in such a marketplace. ISMs also do not necessarily level the playing field for small companies against larger competitors. As a result, companies use such marketplaces mainly to purchase commodity goods, manage their supply chains, and conduct indirect procurement transactions not related to their core business. Business-to-business (B2B) e-commerce is significantly different from business-to-consumer (B2C) e-commerce. While B2C merchants sell on a first-come, first-served basis, most B2B commerce is done through negotiated contracts that allow the seller to anticipate and plan for how much the buyer will purchase. In some cases B2B is not so much a matter of generating revenue as it is a matter of making connections with business partners.

B2C (Business-to-Consumer)

E-Commerce is basically a concept of online marketing and distributing of products and services over the Internet. It is a natural progression for many retailers or marketer who sells directly to the consumer. The general idea is, if you could reach more customers, service them better, make more sales while spending less to do it, that would the formula of success for implementing a B2C e-commerce infrastructure.For the consumer, it is relatively easy to appreciate the importance of e-commerce. Why waste time fighting the very real crowds in supermarkets, when, from the comfort of home, one can shop on-line at any time in virtual Internet shopping malls, and have the goods delivered home directly.Who should use B2C E-Commerce?• Manufacturers - to sell and to retail the business buyers• Distributors - to take orders from the merchants they supply• Publisher - to sell subscriptions and books• Direct Sales Firms - as another channel to reach the buyers• Entertainment Firms - to promote new products and sell copies• Information Provider - to take payment for downloaded materials• Specialty Retailers - Niche marketers of products ranging from candles, coffees, specialty foods, books use it to broaden their customer reach.• Insurance Firms - On-line rate quotes and premium payments have made it easier for this industry to attract and retain customers. In fact, virtually any business that can deliver its products or provide its services outside its doors is a potential user.

C2C (Consumer to Consumer)

E-Commerce has also emerged that allows unknown, un-trusted parties to sell goods and services to one-another. An excellent example of this is found at Ebay, where consumers sell their goods and services to other consumers. To accommodate this activity, several technologies have emerged. Firstly, Ebay allows all sellers and buyers to rate one another. In this manner, future prospective purchasers may see that a particular seller has sold to more than 2,000 customers - all of whom rate the seller as excellent. In another example, a prospective purchaser may see a seller who has previously sold only 4 times and all 4 rate the seller poorly. This type of information is helpful. Another technology that has emerged to support C2C activities is that of the payment intermediary. Pay Pal is a good example of this. Instead of purchasing items directly from an unknown, un-trusted seller, the buyer can instead send the money to Pay Pal. From there, Pay Pal notifies the seller that they will hold the money for them until the goods have been shipped and accepted by the buyer.

RazakSAT in the House.....

RazakSAT is a Malaysian satellite carrying a high-resolution camera. It was launched into low Earth orbit by a Falcon 1 rocket on July 14, 2009. It was placed into an near-equatorial orbit that presents many imaging opportunities for the equatorial region

This satellite is Malaysia's second remote sensing satellite after TiungSAT-1. Originally called MACSAT, RazakSAT's payload is mainly electro-optical, carrying a Medium-sized Aperture Camera (MAC) which is a pushbroom camera with five linear detectors (one panchromatic, four multi-spectral) weighing approximately 50 kg. The entire satellite weighs at about 180 kg.

The then-Prime Minister of Malaysia, Mahathir Mohamad renamed the satellite to RazakSAT in tribute to the second Prime Minister of Malaysia, Abdul Razak or known as the "Bapa Pembangunan Malaysia" (Father of Malaysian Development) for his contribution to Malaysia's development. This was held officially during Mahathir's working visit to Astronautic Technology (M) Sdn. Bhd. (ATSB) in 2003 at its premise in Technology Park Malaysia (TPM) in Bukit Jalil, Kuala Lumpur. It has since moved to its new premises at Hicom-Glenmarie Industrial Park, Shah Alam, Selangor. ATSB is a wholly-owned company of the Minister of Finance Inc. (MOF) and reports to the Ministry of Science, Technology and Innovation (MOSTI), Malaysia.

RADIO CORPORATION OF AMERICA

RCA is a used by three now separate companies descended from a common ancestor, the Radio Corporation of America. Various product lines and business interests of these companies now carry the RCA brand.

Broadcast expansion

By 1926, the market for commercial radio had expanded significantly, and RCA purchased the WEAF and WCAP radio stations and networks from AT&T, merged them with the already-owned WJZ (the predecessor of WABC) New York to WRC (presently WTEM) Washington chain, and formed the National Broadcasting Company (NBC).

Phonograph

In 1929, RCA purchased the Victor Talking Machine Company, then the world's largest manufacturer of phonographs (including the famous "Victrola") and phonograph records. This included a majority ownership of the Japan Victor Company (JVC). The new subsidiary then became RCA-Victor. With Victor, RCA acquired New World rights to the Nipper trademark. RCA Victor produced many radio-phonographs and also created RCA Photophone, a sound-on-film system for sound films that competed with William Fox's sound-on-film Movietone and Warner Bros. sound-on-disc Vitaphone.
RCA began selling the first electronic turntable in 1930. In 1931, RCA Victor developed and released the first 33⅓ rpm records to the public. These had the standard groove size identical to the contemporary 78 rpm records, rather than the "microgroove" used in post-World War II 33⅓ "Long Play" records. The format was a commercial failure at the height of the Great Depression, partially because the records and playback equipment were expensive, and partially because the audio performance was poor (tracking ability depends upon, among other things, the stylus's radius of curvature, and it would require the smaller-radius stylus of the microgroove system to make slower-speed records track acceptably). The system was withdrawn from the market after about a year. (This was not the first attempt at a commercial long play record format, as Edison Records had marketed a microgroove vertically recorded disc with 20 minutes playing time per side the previous decade; the Edison long playing records were also a commercial failure.)
In 1930, RCA became a crucial and key tenant in the yet to be constructed landmark building of the Rockefeller Center complex, 30 Rockefeller Plaza, which from 1933 became known as the RCA building, now the GE Building. This critical lease in the massive project enabled it to proceed as a commercially viable venture.

UTP vs STP

Twisted pair

Twisted pair cabling is a form of wiring in which two conductors (the forward and return conductors of a single circuit) are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from Unshielded Twisted Pair (UTP) cables, and crosstalk between neighboring pairs

A)Unshielded Twisted Pair

Twisted pair cables were first used in telephone systems by Alexander Graham Bell in 1881. By 1900, the entire American telephone line network was either twisted pair or open wire with similar arrangements to guard against interference. Today, most of the millions of kilometres of twisted pairs in the world are outdoor landlines, owned by telephone companies, used for voice service, and only handled or even seen by telephone workers.

UTP cables are found in many ethernet networks and telephone systems. For indoor telephone applications, UTP is often grouped into sets of 25 pairs according to a standard 25-pair color code originally developed by AT&T. A typical subset of these colors (white/blue, blue/white, white/orange, orange/white) shows up in most UTP cables.

For urban outdoor telephone cables containing hundreds or thousands of pairs, the cable is divided into smaller but identical bundles. Each bundle consists of twisted pairs that have different twist rates. The bundles are in turn twisted together to make up the cable. Pairs having the same twist rate within the cable can still experience some degree of crosstalk. Wire pairs are selected carefully to minimize crosstalk within a large cable.

Short for Unshielded Twisted Pair cable, UTP cable is a popular type of cable used in computer networking that consists of two shielded wires twisted around each other.

B)Shielded Twisted Pair

Shielded Twisted Pair Cable is used to eliminate inductive and capacitive coupling. Twisting cancels out inductive coupling, while the shield eliminates capacitive coupling. Most applications for this cable are between equipment, racks and buildings. Shielding adds usually some attenuation to the cable (compared to unshielded), but usually not because in the case of balanced transmission, the complementing signals will effectively cancel out any shield currents, so shield current losses are negligible.

The noise pickup characteritics of twisted pair cable is determined by the following cable characteristics: number of twists per meter (generally more twists per meter gives better performance), uniform cable construction, capacitance balance (less capacitance difference to groud, the better), cable diameter (less are between wires is better) and the amount of shielding (more shielding, the better).

HOW ABOUT TOPOLOGY.....

Topologies in Networking

A network topology is the geometric arrangement of nodes and cable links in a LAN, thats what we learn in the class...need 2 find 2 more types of topologys...MESH n TREE

There are three topology’s to think about when you get into networks. These are the star, ring, and the bus.

Star - a ring topology features a logically closed loop. Data packets travel in a single direction around the ring from one network device to the next. Each network device acts as a repeater, meaning it regenerates the signal.
Ring - in a star topology each node has a dedicated set of wires connecting it to a central network hub. Since all traffic passes through the hub, the hub becomes a central point for isolating network problems and gathering network statistics.
Bus - the bus topology, each node (computer, server, peripheral etc.) attaches directly to a common cable. This topology most often serves as the backbone for a network. In some instances, such as in classrooms or labs, a bus will connect small workgroups.

MESH TOPOLOGY

A type of network setup where each of the computers and network devices are interconnected with one another, allowing for most transmissions to be distributed, even if one of the connections go down. This type of topology is not commonly used for most computer networks as it is difficult and expensive to have redundant connection to every computer. However, this type of topology is commonly used for wireless networks. Below is a visual example of a simple computer setup on a network using a mesh topology.

TREE TOPOLOGY

Among all the Network Topologies we can derive that the Tree Topology is a combination of the bus and the Star Topology. The tree like structure allows you to have many servers on the network and you can branch out the network in many ways. This is particularly helpful for colleges, universities and schools so that each of the branches can identify the relevant systems in their own network and yet connect to the big network in some way.

DEFINITION OF APPLE MAC OS.............





This is the operating system that runs on Macintosh computers. It is pronounced, "mack-oh-es." The Mac OS has been around since the first Macintosh was introduced in 1984. Since then, it has been continually updated and many new features have been added to it. Each major OS release is signified by a new number (i.e. Mac OS 8, Mac OS 9).Since the core of the Mac OS was nearly decades old, Apple decided to completely revamp the operating system. In March of 2001, Apple introduced a completely new version of the Mac OS that was written from the ground up. The company dubbed it "Mac OS X," correctly pronounced "Mac OS 10." Unlike earlier versions of the Mac OS, Mac OS X is based on the same kernel as Unix and has many advanced administrative features and utilities. Though the operating system is much more advanced than earlier versions of the Mac OS, it still has the same ease-of-use that people have come to expect from Apple software

DEFINITION OF MICROSOFT WINDOWS........

Microsoft Windows is a range of commercial operating environments for personal computers. The range was first introduced by Microsoft in 1985 and eventually has come to dominate the world personal computer market. All recent versions of Windows are fully-fledged operating systems.
Windows was developed for IBM PC compatible computers (these were based on Intel x86 architecture), and to this day, almost all versions of Windows are made for this hardware-platform (although some versions of Windows NT were made for other architectures ). The popularity of Windows made Intel CPUs more popular and vice versa. In fact, the term Wintel became used to describe PC compatible computers running a version of Windows.
