其实，我真的放不下你。
爱了你一年多，突然要我这样放弃，
我真的很心痛。
但你对我说，你没办法，你只能选这条路，
那时，我真的很想你明白，人生有很多条路可以选的。。。
而你选这放弃的时候，就等于我就会离开你。

Last two class-RCA JACK
Class Communication and Technology today is the most faster class finished i ever had. After Miss Azura finished the class, she told us how and what to do on our seminar. In the end i know why the class will end so fast already. But luckily also because that day I'm so tired. Haha... There is nothing special for this class.^@^
RCA JACK
------------
An RCA Jack or RCA Plug is a connector commonly used to connect various components in a audio-video system or simple analog transmission. It is used for analog and coaxial digital audio and composite and component video connections.

Tree topology and Mesh topology
This week we got quizzzzzzz..................wuwuwu......i guess my result must below than 8~~~haizzz...sad... Recently the CT study some i already studied in form 6. Haha!!!
Tree Topology
A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable (See fig. 4). Tree topologies allow for the expansion of an existing network, and enable schools to configure a network to meet their needs.
Advantages of a Tree Topology
* Point-to-point wiring for individual segments.
* Supported by several hardware and software venders.
Disadvantages of a Tree Topology
* Overall length of each segment is limited by the type of cabling used.
* If the backbone line breaks, the entire segment goes down.
* More difficult to configure and wire than other topologies.
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.

E- Commerce
This week is the 1st week after i came back from holiday. For this whole month, the night class will begin on 2030. Bwahaha.... 1st at all, the most impression is the cigarette smell came from one guy... And because of it my friend change her place from my right hand side to my left even the chair is broken.
After that, Miss Azura told us to bring the file next week to check. After Miss Azura told us, Silvia already know next week will got quiz. And very sorry, cause our class is very noisy and make Miss Azura angry...
B2B(Business to Business)
Internet-based business-to-business (B2B) 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.
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)
B2C (Business-to-Consumer) 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
C2C(Consumer to Consumer)
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.

Before i talk with them, my mood is very bad. After that, i called them. I talk and talk and they keep cheer me up. I felt that the problem is not really a big deal. Then i begun to move forward. really hope that they will always beside me and also hope that my friend can heal from the cancer...
