THE BROKERAGE MODEL

Whether a company sells products or services to consumers, other businesses, or both, there are many different ways to approach the marketplace and make a profit. Business models, of which the brokerage model is simply one, are used to describe how companies go about this process. They spell out the main ways in which companies make profits by identifying a company's role during commerce and describing how products, information, and other important elements are structured. Just as there are many different industries and types of companies, there are many different kinds of business models. While some are simple, others are very complex. Even within the same industry, companies may rely on business models that are very different from one another, and some companies may use a combination of several different models.

One Internet business model is the brokerage model. At the heart of this model are third parties known as brokers, who bring sellers and buyers of products and services together to engage in transactions. Normally, the broker charges a fee to at least one party involved in a transaction. While many brokers are involved in connecting consumers with retailers, they also may connect businesses with other businesses or consumers with other consumers. A wide variety of different scenarios or business configurations fall under the banner of a brokerage model. These include everything from Web sites posting simple online classified ads and Internet shopping malls (Web sites that sell products from a variety of different companies) to online marketplaces, online auctions, aggregators, and shopping bots.

Community Model

The community model is a method of developing an online presence in which several individuals or groups are encouraged to join and participate in ongoing interaction designed around a common purpose. Web communities, or virtual communities, were not only a way for like-minded people to come together online, they also were an increasingly important element of business plans.
the community model comes in two basic varieties: those centered on relationships and those centered on tasks. The former typically are informal, grassroots-oriented communities that revolve around shared interests, ideas, topics, and goals. In these communities, the development of relationships is the primary goal. To maximize member involvement, community sites must offer maximum degrees of interactivity and personalization. For example, GeoCities offers space and tools for members to set up their own Web sites and establish virtual communities within the broader GeoCities community. Task-centered communities generally are more structured and impersonal. The relationships established or augmented online are a means to a mutual end, such as enhanced profits. More specifically, Web communities are established between business partners, between businesses and their customers, between different groups of customers, within companies, and between individuals and groups devoted to particular topics.

In business-to-business (B2B) relationships, the community model provides all community members with the ability to share and check electronic invoices, communicate and exchange funds on secured networks, and resolve problems quickly and openly. Internet communities offer exceptionally streamlined workflow processes between and within companies, where the functionality of key tasks is integrated and synthesized. This necessitates less personnel, paperwork, and software, and boosts efficiency, thereby minimizing operating costs and enhancing profit margins.

COMPARISON ROUTER AND SWITCH

Router Switch
  • Basically, a router is used to connect computers belonging to one network with those belonging to another or other networks. Thus, a router connects two or more different networks.
  • A switch on the other hand, connects different computers within one network.
  • As per the OSI model, a router is a Network Layer device, i.e. it operates at Layer 3.
  • Unless it is a multi-layer switch, a network switch operates at Layer 2 (Data Link Layer).
  • Routers are much more sophisticated and intelligent network devices, as compared to switches.
  • In comparison with routers, switches are less sophisticated and less intelligent.
  • A router works on the principle of IP addresses.
  • A switch works on the basis of MAC addresses.
  • A router's inbuilt hardware makes use of routing algorithms to compute the best possible path for routing data packets across different computer networks.
  • A switch does not perform any such activities.
  • Routers have their own inbuilt operating systems and they need to be configured before use.
  • Most switches do not require any prior configuration and are usually 'ready-to-use'.

COMPARISION BETWEEN SWITCH AND HUB

Switch Hub
  • As per the OSI model, network switches are classified as Data Link Layer devices, i.e. they operate at Layer 2. However, certain multi-layer switches can operate at higher layers as well.
  • As per the OSI model, a hub is a Physical Layer device, i.e. it operates at Layer 1.
  • A switch is a more sophisticated network device and is more expensive than a hub.
  • A hub is a very primitive device and is comparatively much cheaper.
  • A switch is an intelligent device, it transmits the data packets from the source computer to only those network computers to which the data packets are originally intended.
  • A hub is a 'dumb' device to say the least. It broadcasts the data packets to each and every networked computer, and not just the target computer or set of computers to which the data packets were originally intended to be sent.
  • There is optimum utilization of network bandwidth in case of switches, and bandwidth wastage is minimal.
  • Due to their broadcast mechanism of data transmission, there is unnecessary wastage of network bandwidth which results in slow operation and data transfer speeds.
  • Switches are full-duplex devices, i.e. both, data transmission and reception can take place simultaneously.
  • Hubs are half-duplex devices, i.e. both, data transmission and reception cannot take place simultaneously.
  • Thanks to its broadcast mechanism, network security becomes a big issue and a loophole in the case of a hub.
