Decision Support Systems Used in Network Hardware Essay

The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP).

But how does it work? The internet, based on the concept of “packet switching”, involves the travelling of small packets of data over one or more networks (Frenzel, 2013). This can be compared to “electronic postcards”, meaning that “a computer generates a piece of data and flings it into the net, just like the postal system, except 100 million times faster” (Cerf, 2013). This concept allows one computer to speak to many different computers around the network by sending out these “electronic postcards”. However, before these networks can work seamlessly together, they must use a common protocol, or set of rules for transmitting and receiving these packets of data. There are several protocols currently in use, including the OSI Model, the TCP/IP Model, UDP, HTTP, and FDP (Mitchell, 2014), but the most commonly used is Transmission Control Protocol/Internet Protocol (TCP/IP) (Gilmer, 2011). Even as early as 1977, TCP/IP was being used by other networks to link to ARPANET (Kozierok,

Router is a device for networking that sends packets of data between the networks of a computer. The packet of data is forwarded to routers of the networks that contain the internetwork until the packet is at the destination node. A router can be linked to several data lines from various systems. The router reads the address information in the packet to establish the ultimate destination when the data packet is in any data lines (Liu, 2012).

A Router is a Layer 3 or Network layer device that connects a network to another network. It connects networks with the same protocol such as RIP (Routing Information Protocol) and IP (Internet Protocol).

A router is a network device, typically connected to a variety of LAN and WAN interfaces, that forwards packets based on their destination IP addresses.

The reason 2013 intangible assets make up more of the total assets compared to 2013 intangible assets is due to the NDS acquisition that occurred in 2013

Most business networks today use switches to connect computers, printers and servers within a building or campus. A switch serves as a controller, enabling networked devices to talk to each other efficiently. Routers, on the other hand, are a much more sophisticated piece of technology. They are small like a switch and look like modems in which multiple nodes can be connected. Today’s routers are actually designed for the purpose of connecting multiple ‘area networks’ (both local and wide). In terms of the internet, routers actually serve as a temporary destination for network traffic. Routers are capable of transmitting and receiving data packets but will actually ‘read’ the packet to get its IP address for determining the packet’s destination. Unlike the switch, routers are capable of joining the multiple networks together; in the case of Kudler Fine Foods, their three store locations. “Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size.” (FCITC, 1997) There are four basic types of cable: Unshielded Twisted Pair (UTP), Shielded Twisted Pair (STP), Coaxial Cable, and Fiber Optic Cable. Unshielded twisted pair can range from basic telephone-grade wiring to high-speed cabling. This cable consist of four pairs of wires inside the outer covering each pair twisted with a different number of twists per inch to reduce/eliminate interference from adjacent pair or other devices. The tighter the twisting the higher data rates it supports but it also will increase the cost of the cable. Shielded twisted pair cables are actually shielded from radio and electrical frequencies and

1. Study the networked supply chain concept as implemented by Cisco. What are its strengths and weaknesses?

After knowing the benefit and limitation of Decision Support System (DSS), we should consider the following points before creation of successful DSS. Even the existing system, which are away from these point, can consider the same for future enhancement. Below are most important factors to bring success to DSS while using -

1. Create a strategy to leverage the knowledge base of the practice against the value of knowledge within the developing ACOs.

Physical media is what physically connects the computers connected on the internet. For this network two physical media will be used to allow access to the application layers of the system. The coaxial cables will be used to create a WAN. While a wireless protocol will be used in allowing users to roam within the network. A LAN will be represented as follows;

Cisco Systems is a global market leader and innovator of computer communications and networking solutions. Established in the 1980’s, the company rapidly developed into the world’s greatest manufacturer of internet routers and was/is a foremost provider of commercial communication network devices. The aim of this case study report is to create an understanding of Cisco’s historical international business activities as well as explore their recent and current developments in international business management. The ‘Recent Development’ section details both Cisco’s main strategy of Acquisitions and how the company has operated under and coped with new management.

Every home that has internet connectivity has a router. Just like the name suggest, a router makes routing decisions in networking. What this means is, the router is responsible for directing packets or data from one network node to another node. A node simply is a device on a network, i.e. Desktop, server, laptop etc. In this description, I will explain in simple terms exactly how a computer on a network is able to send a packet or information to each other with precision through a router.

Decision support system is an interactive computer based support system that aids decisions making in an organization. It helps any organization or even a small sized business in decision making process. An appropriately planned Decision Support System is an intuitive programming based framework expected to help leaders gather valuable data from crude information, records, individual learning, and/or plans of action to recognize and take care of issues and decide. This can be completely computerized, human or both.

Group decision support systems (GDSS) are interactive, computer-based systems that facilitate solution of semi-structured and unstructured problems by a designated set of decision-makers working together as a group. A GDSS can assist groups, especially groups of managers, in analyzing problem situations and in performing group decision making tasks. GDSS include structured decision tools for tasks like brainstorming, commenting on ideas, and rating and ranking of alternatives
