An RCA connector is a plug and a jack designed for use with coaxial cable for frequencies ranging from the very lowest up to several megahertz. An RCA connector is sometimes known as a phono plug and jack.
The male RCA plug consists of a central pin measuring approximately two millimeters (mm) in diameter, and an outer shell whose inside diameter is approximately six mm. The plug shell is slotted rather than threaded, to facilitate quick insertion to, and removal from, the female jack or receptacle. Contact is maintained by physical pressure between the slotted shell of the plug and the smooth cylindrical barrel of the jack. The plug shell is connected to the outer conductor, or shield, of the coaxial cable, normally at electrical ground. The center pin of the plug is connected to the cable center conductor, which carries the signal. In the jack, the barrel is grounded and the center hole is plated inside to conduct the signal.
RCA connectors are suitable for audio-frequency (AF) applications. They are also used in radio-frequency (RF)systems at low and medium frequencies, and at power levels up to approximately 100 watts. At higher frequencies or higher power levels, larger connectors are necessary. RCA connectors are designed for cables with small outside diameters (less than 6 or 7 mm) and are intended for indoor use only.

Mesh Topology & Tree Topology
A Mesh topology Provides each device with a point-to-point connection to every other device in the network. These are most commonly used in WAN's, which connect networks over telecommunication links. Mesh topologies use routers to determine the best path.
Mesh networks provide redundancy, in the event of a link failure, meshed networks enable data to be routed through any other site connected to the network. Because each device has a point-to-point connection to every other device, mesh topologies are the most expensive and difficult to maintain.
Tree Topology also known as a star bus topology, tree topology is one of the most common types of network setups that is similar to a bus topology and a star topology.

Coaxial cable, or coax, has a single, solid copper core, which is wrapped in a dielectric, a copper outer conductor, and a PVC covering. The outer conductor can be woven mesh or solid copper.
The advantages of coax include the following:
- Broadband system—Coax has a sufficient frequency range to support multiple channels, which allows for much greater throughput.
- Lower error rates—Because the inner conductor is in a Faraday shield, noise immunity is improved, and coax has lower error rates and therefore slightly better performance than twisted-pair. The error rate is generally 10–9 (i.e., 1 in 1 billion) bps.
- Greater spacing between amplifiers—Coax's cable shielding reduces noise and crosstalk, which means amplifiers can be spaced farther apart than with twisted-pair.
The main disadvantages of coax are as follows:
- Problems with the deployment architecture—The bus topology in which coax is deployed is susceptible to congestion, noise, and security risks.
- Great noise—The return path has some noise problems, and the end equipment requires added intelligence to take care of error control.
- High installation costs—Installation costs in the local environment are high.
Fiber optic systems have many attractive features that are superior to electrical systems. These include improved system performance, immunity to electrical noise, signal security, and improved safety and electrical isolation.
The advantages of Fiber optic systems include the following:
- Greatly increased bandwidth and capacity
- Lower signal attenuation (loss)
- Immunity to Electrical Noise
· it is not susceptible to electromagnetic or radio frequency interference
The main disadvantages of fiber optic systemsare as follows:
· expensive over short distance
· requires highly skilled installers
· adding additional nodes is difficult
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.
The advantages of twisted pair include the following:
- It is a thin, flexible cable that is easy to string between walls.
- Because UTP is small, it does not quickly fill up wiring ducts.
- UTP costs less per meter/foot than any other type of LAN cable.
The main disadvantages of twisted pair are as follows:
· Susceptibility to inference and noise
· Attenuation problem (For analog, repeaters needed every 5-6km)
· Relatively low bandwidth (3000Hz)

e-commerce ,MyEG & Rilek portal
-Business conducted between companies, rather than between a company and individual consumer. An example of B2B company is a firm that makes parts that are sold directly to an automobile manufacturer.
Business To Consumer (B2C)
-Business conducted between companies and indivdual consumer, rather than between two companies. An retailer like Wal-Mart is an example of a B2C company.
Customer To Customer (C2C)
-A type of business model that faciltates interaction between customers. Customer to customer business provides individuals with a place to converse, exchange and interact with other people. Many C2C business have onlne operations. Online auctions and classfieds such as Ebay and Craig's List are examples of very successful customer to customer business models. These sites don't look directly sell goods to their members, instead the customers are exchanging with other customers.
MyEG Services Berhad is concessionaire for the Malaysian E-Government MSC Flagship Application. They role as a Service Provider for the E-Services component essentially provides the electronic link between the Government and citizens or businesses. Through this portal, also offer the Malaysian public a single point of contact between the Government and the people it serves. This portal enables Malaysians to dynamically interact with numerous agencies with the Federal, State and the Local Government machinery providing services ranging from information searches to licenses applications.
RILEK PORTAL represents reliability, simplicity and security. RILEK is equipped with high-end multimedia facilities and system support to accommodate heavy traffic flow. In addition, it is capable of processing information at an efficient and high-speed rate. RILEK promotes a hassle-free and innovative lifestyle that is designed to eliminate queues and frustrations.

Microsoft Window & Apple Mac
Windows
It is the operating system by Microsoft, it is the one, that most home users use and it is also the one, that most games and stuff are developed for (maybe after game consoles like PlayStation etc.). Windows is a pre-compiled system, so you install a finished package on you computer and it is supposed to work right from the start. It can NOT be installed on any computer, not Power PCs for example.
MacOS X:
This is a quite young system by the company apple, it is based on the first system: UNIX (very stable), but unlike UNIX it has a GUI (Graphical User Interface).
The current version is called OS X Tiger; it is also what I am using. OS X used to only work on special Apple Computers (the ones with the nice Design, iMac, iBook, etc.) but now they're making it compatible to the Intel-architecture too.
