By use of TCP/IP, several computers on small network in a department can use these protocols in conjunction with other protocols on a single LAN. In this protocol suite, the IP components helps in routing form the small LAN in that department to regional and also to the global internet. TCP/IP is made up of layers which enable it to perform its tasks. The IP part is responsible of moving packet from one node to the other based on the destination IP address. This IPs are mainly assigned by the internet authorities to service providers and thus making it easier for computers to communicate because the IPs assigned to them makes them unique and thus packets can move from source to destination all over the world.
It is used to segment a network and hold back frames that are intended for the local area network while transmitting those that are needed to be sent to the other networks. This improves level of privacy since the information intended for one network cannot be listened on the other connected network. It also reduces traffic and collisions on all networks. A bridge connecting two networks The difference between a switch and a bridge is that each port on a switch is its own collision domain. A collision domain is formed between any two connected devices via a sw... ... middle of paper ... ...so a trusted method of securing data and used as an internet standard.
Decision Support Systems Used in Network Hardware How does data pass through the internet? If you said decision support systems, you are correct. In an indecisive world, network hardware devices uses decision support systems (DSS) to efficiently and effectively route data, in a local area network, with the least amount of errors and inconsistencies. Decision support systems are the brains behind network hardware, and would be near impossible for them to work without the intelligent core of each distinct DSS. There are a variety of network hardware devices: switches, hubs, and routers; and they all use algorithms/procedures to transfer data towards the correct destination.
One of most basic examples of this is a two tin can’s on a string; they are connected to each other just so the two can communicate. This relationship can also be observed with two computers connected with a crossover Ethernet cord. This method of connection is also used for communication through telephone, but this is achieved logically. Switched telecommunications systems are used to create a link between two phones to connect them and allow communications between the two and then dropped when the connection is no longer needed. Point to Point communication in modern times is still prevalent, but achieved using more complex networks with the help of logical networking, and can be used to describe many of the connections between individual parts of a network.
1.0 INTRODUCTION For mini project of this subject, I choose to analyze performance management of different Wi-Fi based on context Wi-Fi service provided in my house area which is SriPuteri WifiNet. To analyze the performance management, I have to identify the problem statement, scope and method to use. In Local Area Network (LAN), although multiple device such as PC, laptop, mobile phone and many more can connected to Wi-Fi but as the increasing of device used, the network can become slower because of data traffic congestion. To overcome the problem, it is essential to have a good Network Management plans. In Network Management, there are three main aspects that must considered which is Security, Performance and Reliability.
Switchers have the ability to create VLANSs (Virtual LAN). According to (Pintello, 2013) A VLAN refers to a group if hosts that share a common set of requirements for communication and are grouped together via Layer 2 of the OSI Model. VLANs are also used to make networks more secure. Switches form one-to-one connections between a... ... middle of paper ... ... In this way, it is easy to switch an algorithm without being necessary to modify the protocol.
Routers primarily route data packets to other networks. They provide the interfaces between external and internal networks (the Internet and a LAN, for example). A router usually contains other functions such as firewalls, traffic monitoring, VPN, and more services. Security Review According to the SciTechConnect blog , “In today’s network infrastructures, it is critical to know the fundamentals of basic security infrastructure. Before any computer is connected to the Internet, planning must occur to make sure the network is designed in a secure manner.

Why? Routers are used to connect networks together and they also do the following network functions. FUNCTIONS OF A ROUTER • Control broadcasts on the LAN • Act as the default gateway • Translate protocols when necessary • Send data to different networks • Learn and advertise loop free paths • Show the most efficient path to reach the correct destination At the physical, data link and network layer Networks (most of the time Ethernet) use broadcast communication. Transmissions on the network layer broadcast to all devices or servers on the network layer. Network broadcast communication i... ... middle of paper ... ...een programmed this way, and finds routes based off of other routers.
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.
