(i)Mesh Topology:



The Mesh Topology is 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.

(ii) Tree Topology



The 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 . The tree topologies allow for the expansion of an existing network, and enable schools to configure a network to meet their needs.

As Miss Azura promised in the last lesson, today we'll be given a "pop quiz". Unfortunately she is absent because she falls sick so our quiz is conducted by another lecturer to replace Miss Azura. Anyway i hope that she'll get well soon. ^-^

Ermm....today nothing special, everyone as usual enter class and lesson still goes on. When Miss Azura enter the class, she is wearing a mask. She shows a very good example to us because H1N1 is getting serious in Malaysia. In class, she also mentions about our "pop quiz" which going to be held on next lesson.

Besides searching what is My EG Portal and Rilek Portal, Miss Azura also wanted us to find info bout E-Commerce.

1. B2C
Business-to-consumer e-commerce, or commerce between companies and consumers, involves customers gathering information; purchasing physical goods or information goods and, for information goods, receiving products over an electronic network.
It is the second largest and the earliest form of e-commerce. Its origins can be traced to online retailing (or e-tailing). Thus, the more common B2C business models are the online retailing companies such as Amazon.com, Drugstore.com, Beyond.com, Barnes and Noble and ToysRus. Other B2C examples involving information goods are E-Trade and Travelocity. The more common applications of this type of e-commerce are in the areas of purchasing products and information, and personal finance management, which pertains to the management of personal investments and finances with the use of online banking tools. B2C e-commerce also reduces market entry barriers since the cost of putting up and maintaining a Web site is much cheaper than installing a “brick-and-mortar” structure for a firm. In the case of information goods, B2C e-commerce is even more attractive because it saves firms from factoring in the additional cost of a physical distribution network. Moreover, for countries with a growing and robust Internet population, delivering information goods becomes increasingly feasible.

2. C2C
Consumer-to-consumer e-commerce or C2C is simply commerce between private individuals or consumers. This type of e-commerce is characterized by the growth of electronic marketplaces and online auctions, particularly in vertical industries where firms/businesses can bid for what they want from among multiple suppliers.16 It perhaps has the greatest potential for developing new markets.
This type of e-commerce comes in at least three forms:
(i) auctions facilitated at a portal, such as eBay, which allows online real-time bidding on items being sold in the Web;
(ii) peer-to-peer systems, such as the Napster model (a protocol for sharing files between users used by chat forums similar to IRC) and other file exchange and later money exchange models; and
(iii) classified ads at portal sites such as Excite Classifieds and eWanted (an interactive, online marketplace where buyers and sellers can negotiate and which features “Buyer Leads & Want Ads”).

3. B2B
B2B e-commerce is simply defined as e-commerce between companies. This is the type of e-commerce that deals with relationships between and among businesses. About 80% of e-commerce is of this type, and most experts predict that B2B e-commerce will continue to grow faster than the B2C segment. The B2B market has two primary components: e-frastructure and e-markets. Efrastructure is the architecture of B2B, primarily consisting of the following:
(i) logistics - transportation, warehousing and distribution (e.g., Procter and Gamble);
(ii) application service providers - deployment, hosting and management of packaged software from a central facility (e.g., Oracle and Linkshare);
(iii) outsourcing of functions in the process of e-commerce, such as Web-hosting, security and customer care solutions (e.g., outsourcing providers such as eShare, NetSales, iXL Enterprises and Universal Access);
(iv) auction solutions software for the operation and maintenance of real-time auctions in the Internet (e.g., Moai Technologies and OpenSite Technologies);
(v) content management software for the facilitation of Web site content management and delivery (e.g., Interwoven and ProcureNet); and
(vi) Web-based commerce enablers (e.g., Commerce One, a browser-based, XML-enabled purchasing automation software).
E-markets are simply defined as Web sites where buyers and sellers interact with each other and conduct transactions.
The more common B2B examples and best practice models are IBM, Hewlett Packard (HP), Cisco and Dell. Cisco, for instance, receives over 90% of its product orders over the Internet. Most B2B applications are in the areas of supplier management (especially purchase order processing), inventory management (i.e., managing order-ship-bill cycles), distribution management (especially in the transmission of shipping documents), channel management (i.e., information dissemination on changes in operational conditions), and payment management (e.g., electronic payment systems or EPS).

Unbelieveable!!!! Today's lecture is still Computer Technology! We've been touching this topic for the past 2 lessons! I wonder when we will be learning the next topic....=.= Besides lecture, Miss Azura also asked us to find what is "My EG Portal" and "Rilek Portal".

My EG portal is principally engaged in the business of development and implementation of Electronic Government (E-Government) services and the provision of other related services for the E-Government Initiative as well as investment holding. The E-Government Initiative is a Government programme which focuses on delivering improvements in terms of how the Government operates internally, and how it delivers services to the people. The overall E-Government Initiatives focuses on allowing citizens to retrieve information and perform transactions with various Service Suppliers in a convenient and timely manner by utilizing its Electronic Services (E-Services). The main Service Suppliers that currently employ our E-Government services and solutions are:
i. Dewan Bandaraya Kuala Lumpur ("DBKL")
ii. Jabatan Insolvency Malaysia ("JIM")
iii. Jabatan Pengangkutan Jalan ("JPJ")
iv. Polis Diraja Malaysia ("PDRM")
v. Tenaga Nasional Berhad ("TNB")
vi. Telekom Malaysia Berhad ("TMB")

Rilek portal is the revolutionary way to perform all your e-government services:
i. Jabatan Pengangkutan Jalan (JPJ)
ii. Polis DiRaja Malaysia (PDRM)
iii. Telekom Malaysia Berhad (TMB)
iv. Tenaga Nasional Berhad (TNB)
Besides that, Rilek portal provide easy transactions electronically through various delivery channels and offers JPJ Driving Licenses services, summons payments and inquiries on Kejara points. Their services also include electronic utility bill payment for TNB and Telekom bills.

After one week holiday due to infection of H1N1 in UUM, all classes seems started as usual today. But most of my classmates, including me, feel very tired because most of us jz arrive back UUM early in the morning. Although tired, we still need to attend the class. Hai..... Today's lecture is bout Computer Technology again (continue from last lecture). Miss Azura gives more explainations and details about computer so that we can understand deeper.

CCT1023 Group A (26 July 2009)

Everyone goes to class as usual in the morning to hand up our individual assignment to Miss Azura. Unfortunately, our assignments appear to have few mistakes and were corrected by our lecturer. Those who has mistakes are required to do correction and pass up on the next day. But I managed to correct my assignment and handed on the same day. I wish Miss Azura will "close one eye" and give us full marks...hahaha...
