The shape of a network can take many different forms and these topologies can be connected by a variety of means. The differing topologies are Mesh, Bus, Ring and Star and each one will be examined and the advantages and disadvantages explored. These networks can be connected via Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI) or wireless. Each of the connection methods will also be analyzed and the differences will be explained.
The term network topology refers to the physical layout of computers, cables, and other components that make up a network. The choice of one topology over another is important for the network professional and will have an impact on the type of equipment the network needs, the capabilities of the equipment, the growth of the network and the way the network is managed. The different types of topologies each require different communication methods and these will also have an influence on the network.
The first topology to be discussed is the bus topology. It consists of devices that are connected to a common shared cable. The bus topology is the simplest and most common method of networking computers with the computers set up in a straight line. The single cable that feeds all of the computers is known as the trunk (also called backbone or segment) and connects all of the network computers in a single line. The computers communicate by addressing data to a certain computer and sending out the data onto the cable via electronic signals. The signal is sent out on the bus and only the computer whose address matches the address encoded in the original accepts the information. A disadvantage of the bus topology is that only one computer can send data at a time and this limits the number of computers that can be on the network. The more computers on the bus, the more computers will be waiting to put data on the bus and slow down network performance. Another disadvantage is that if the trunk breaks or is becomes un-terminated, the network will cease to function since the signal will bounce. The advantage to a bus network is that if one computer on the bus fails, it will not affect the others on the bus.
A star topology has cable pieces from each computer connected to a central hub. The signals are transmitted from the sending computer through the hub to call computers on the network.
A bus is a communication system that connects multiple subsystems within a computer. An average computer system normally consists of several components such as a central processing unit, memory devices, and input/output (I/O) devices. The bus system consists of linking media like wires and connectors, and a bus protocol. Buses can be categorized as serial or parallel and synchronous or asynchronous. The bus lets the different components communicate with each other by allowing information to flow between units and devices.

“Network topology is the arrangement of the various network elements such as node, link, of computer network. Basically, it is topological structure of a network which ether be physically or logically.”
In “Connectivity and its Discontents,” Sherry Turkle discusses how often we are found on our technology. Turkle states in her thesis “Technology makes it easy to communicate when we wish and to disengage at will.” In the essay are interviews on several different people, of all ages to get their view on the 21st century. Teens are starting to rely on “robot friendships,” the most communication teens get are from their phones. Are we so busy trying to connect to the media that we are often forgetting what is happening around us?
Point-to-Point routing system, unlike low-cost competitors that utilize hub-and-spoke system, partnering with larger airlines to provide connecting flights.
To attempt to define a network in a few sentences would be a fool’s errand. A network could be seen as simply a grid of interconnecting connections between multiple bodies. However when this vision is applied to real-world systems, they all start to differ. There is not anything that exists in the universe that is not part of a network. A network is the result of different parts or members which have similarities in parts of their identity. This similarity that they have in common, they will also have with other bodies forming a network between them. Most of these factors of identity are different from those of most others. As a result, each factor will be in common with different other members of different networks. Each factor includes this body in a multitude of networks. This means that no one thing is in one and only one network, but is included in many.
The techniques of discipline, which are exhibited most by the prison of Mettray who used the division of the inmate population into hierarchical groups and constant supervision to transform criminals into docile bodies, are still in place today because of the implications they have in medicinal and judicial models. The carceral network and its influence on society has transformed society from a punitive model into a penitentiary model that produced delinquents, transformed the focus from order and offenses to the norms of society, and legalized the power to punish (the great economy of power). The carceral network also allowed the focus of the penal system to mainly focus on punishing and judging normality, allowed for inmates to be captured
In the article, “Connectivity and Its Discontent,” by Sherry Turkle, the author discusses the relationship between human beings and technology. First, the author begins the article by explaining why people choose to text message because it is easier compared to face to face contact. On the other hand, technology can prevent a person from feeling lonely and having power to control a conversation. In addition, the author states how a person can multitask while communicating with someone on video chat, yet a person can feel at times guilt-ridden by ignoring a person sending emails while socializing on video chats. Meanwhile, Turkle contends that some people are choosing to be closer to their devices by focusing on themselves and not show consideration
Network topology can be defined in many ways since there are many different types of network that depending on the certain amount of user, ability, and purpose. For example, in Multimedia University (MMU) all networks inside our campus are connected through Local Area Network (LAN) to access MMLS for example. While when connected to outside through internet, we call it Wide Area Network (WAN). We are connected to the world via various network topologies, such as Point-to-point, Bus, Star, Ring, Mesh, Tree, Hybrid, and last but not least Daisy chain. Our interest regarding this Final Year Project is Wireless Mesh Network build based on Mesh Topology.
The Jaagz’ local area network will use category 5 cable and run IEEE 802.3 protocol. Using IEEE 802.3, the network speed will average about 10 Mbps. It will utilize a combination of a star and bus topology, which is the most common topology used in networks. The bus topology makes up the backbone of the network while the star topology branches out.
In this topology, all nodes are connected to a central device, usually a hub or a switch. Each connected device has a dedicated, point-to-point connection between the device and the hub. The star network topology is by far the most widely implemented topology in use today.
A model developed for using factor analysis to try to determine the key traits in human personality. Although trait theories were well established by the 1960s, there was no consensus concerning the number or nature of the traits that make up personality. Since then, further research has confirmed a basic five factor model of personality or ‘Big Five’ (Tomas 2007). This five factor structure has been replicated by Norma (1963), Borgatta (1964) and Digman and Takemoto-Chock (1981) in list derived from Cattle’s 35 variables (Lawrence &Oliver 2000).
Production Functions A production function in general, without specifying what kind, is related to the output of a production process which starts with the factors of production. Production functions are an integral part of explaining marginal products as well as allocative efficiency. There are different classifications for production functions, and what constitutes them, determined by the type of production. This article of the WIKI aims to focus on the Substitional production function, explaining what it is and means, as well as the limitations, of doing the same.
A bus network is a network topology in which nodes are directly connected to a branched half-duplex link called a bus. A star topology is a topology for a Local Area Network in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable, but the benefit is that if a cable fails, only one node will be brought down. Advantages of using a star topology include fast connection speed because each workstation has a dedicated cable, it will not slow down when many users are on-line and new workstations can be added without affecting the other workstations.
The term Topology refers to the physical or logical shape or layout of a network. Communication between different nodes within a network is determined by its topology. Mesh, Bus, Ring and Star are four of the most common network topologies, each with advantages and disadvantages in relation to each other.
