Today,Miss Azura wan us find information about the RCA.Below are the detail about RCA.

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.

That day, Miss Azura continue her Chapter 6 part 3...also about the telecommunication...we learned about the facsmile systems and paging systems....we all felt interested about the pager because our father had been used pager before when we stil young...
We learned detailly about the telecommunication in 5 part..there are facsmile, paging, satellite, telephone systems and cellular phone systems....
Lastly, Miss Azura announced that next Wednesday canceled her class...we all felt happy and thankful because most of us already go back to our hometown...thanks ya, Miss Azura!!!

SCCT 1023(A) 6-9-09 Sunday

Today, Miss Azura teached us about the chapter about telecommunication.
We will knowed more about the ability of the telephone and cellular phone technology like GPRS, GSM, EDGE and more. Although we always saw those terms occur in our handphone service or broadband services but we also don't really understand what the meaning of those terms...
Through the lesson on that day, we all know more detailly about the terms and gain more the knowledge about the telecommunication.

This Wednesday, Miss Azura want us find infomation about Razak Sat...below are the details about Razak Sat...

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 unique near-equatorial orbit that presents many imaging opportunities for the equatorial region.

RazakSAT is unique as it will be the first microsatellite of its class to be placed at Near equatorial orbit (NEqO); unlike many other satellites of its kind that are placed on Sun-Synchronous Orbit (SSO). RazakSAT's orbital inclination will coincide with the latitude of its launch at Kwajalein, and that of the northernmost extent of Malaysia. Thus its launch will be nearly due east and quite efficient.

This is especially important because Malaysia is usually covered by the equatorial cloud bands. Normal sun-synchronous optical satellites, which may re-visit an area only once every 14 days, will almost never be able to see the ground during their pass. As a result, much optical imagery of Malaysia is years out of date.RazakSAT, on the other hand, will revisit some part of Malaysian territory every 90 minutes, maximising its ability to exploit gaps in the clouds, and substantially improving coverage of the country as a result.

Today, Miss Azura teached us about the chapter 5 part two...we learn more about communication device, LAN and more...After that, she want us to find some information about the MESH TOPOLOGY and TREE TOPOLOGY...

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

Also known as a hierarchical network.

The type of network topology in which a central 'root' node (the top level of the hierarchy) is connected to one or more other nodes that are one level lower in the hierarchy (i.e., the second level) with a point-to-point link between each of the second level nodes and the top level central 'root' node, while each of the second level nodes that are connected to the top level central 'root' node will also have one or more other nodes that are one level lower in the hierarchy (i.e., the third level) connected to it, also with a point-to-point link, the top level central 'root' node being the only node that has no other node above it in the hierarchy (The hierarchy of the tree is symmetrical.) Each node in the network having a specific fixed number, of nodes connected to it at the next lower level in the hierarchy, the number, being referred to as the 'branching factor' of the hierarchical tree.

1.) A network that is based upon the physical hierarchical topology must have at least three levels in the hierarchy of the tree, since a network with a central 'root' node and only one hierarchical level below it would exhibit the physical topology of a star.

2.) A network that is based upon the physical hierarchical topology and with a branching factor of 1 would be classified as a physical linear topology.

3.) The branching factor, f, is independent of the total number of nodes in the network and, therefore, if the nodes in the network require ports for connection to other nodes the total number of ports per node may be kept low even though the total number of nodes is large – this makes the effect of the cost of adding ports to each node totally dependent upon the branching factor and may therefore be kept as low as required without any effect upon the total number of nodes that are possible.

4.) The total number of point-to-point links in a network that is based upon the physical hierarchical topology will be one less than the total number of nodes in the network.

5.) If the nodes in a network that is based upon the physical hierarchical topology are required to perform any processing upon the data that is transmitted between nodes in the network, the nodes that are at higher levels in the hierarchy will be required to perform more processing operations on behalf of other nodes than the nodes that are lower in the hierarchy. Such a type of network topology is very useful and highly recommended.
