Recommended: Importance of networking computers

Introduction
In this modernize world, internet and network are very vital and important not only for individuals but also for companies, organization, institution, etc. Because of this, it is very important to make use of as many network devices available. We need to study more or at least to have a glimpse of information about the networking devices before we choose or start using it. There are many networking device out there that able for us to study but the chosen device for this report are hub, switch, router and repeater.
Hub
When it comes to networking, a hub is a simple device that joins more than one computers together into one central connection points via LAN. The single network segment are formed by joining multiple computers or other network devices connected using a hub. Hubs are used for twisted-pair cabling when are used on the network. Hub essentially receives incoming packets that been sent and broadcast all these packets to all device that connected on the network under the hub device. Ethernet hub, active hub, network hub, repeater hub and multiport hub is an example of hub.
Hubs that are used on LAN are under the star topology. That is because when one device in the hub are disconnected it is still connected. That why the hubs are categorize under the star topology.
An Ethernet hub is also called multiport repeater. It is used to increase the signal as it passes through it and to prevent the effects of attenuation. Ethernet hubs are vary when it comes to bandwidth that they support. The number of ports an Ethernet hub support also can be vary. The commonly used Ethernet hubs in home networks are four and five port Ethernet hubs. The newer Ethernet hubs devices are much smaller compare to the older devices....

...This device allow data rate up to 100Mbps. It also Enclosure rating of IP67 for outdoor conditions.
Network repeaters are used to boost in coming wireless signal or electrical signal. By using the repeater together with physical media like Ethernet cable or Wi-Fi, the amplified data transmission will only span limited distance before the signal starts to degrade.
All the devices that been studied above each play it unique role in network works that are deeply affected our daily lives. For example without hubs it really impossible for more than one computers to link to one line. It is really hard to implement a long distance connections without a repeater to support and amplifies the signal. Without switch, it is impossible to switch from one port to another port. Without routers it is hard to divide a large network into separate parts thus saving cost and money.

    ... access to what and in which sequence. The router connects the LAN to other networks, which could be the Internet or another corporate network so that the LAN can exchange information with networks external to it. The most common LAN operating systems are Windows, Linux, and Novell. Each of these network operating systems supports TCP/IP as their default networking protocol. Ethernet is the dominant LAN standard at the physical network level, specifying the physical medium to carry signals between computers, access control rules, and a standardized set of bits used to carry data over the system. Originally, Ethernet supported a data transfer rate of 10 megabits per second (Mbps). Newer versions, such as Fast Ethernet and Gigabit Ethernet, support data transfer rates of 100 Mbps and 1 gigabits per second (Gbps), respectively, and are used in network backbones.

    Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.

    A Hub is a networking device that allows one to connect multiple PCs to a single network. Hubs may be based on Ethernet, Firewire, or USB connections. “A switch is a control unit that turns the flow of electricity on or off in a circuit. It may also be used to route information patterns in streaming electronic data sent over networks. “

Now with the improvement of the telecommunications, the Ethernet became what we know today as Internet. I don't think that mass transportation is going to change that much, its going to change but not as fast as telecommunications and technology. I think that telecommunications and technology are the key of the door called future.

    A reason why Wi-Fi is the most important invention is because of safety. I can go on CNN's or NBC's website and find out about what is happening in the world, not only that, I can find out what is happening in my region. I have the ability to read about storms, such as hurricanes or blizzards that can affect me. I can also sign up for alerts that are sent right to my phone immediately warning me. In the summer there was a heavy rainstorm. Trees were falling down and it was dangerous. I received a tornado alert on my phone, because of that I knew that a tornado and power outage could take place anytime. Also, I can find shootings or fires that have happened or are happening in my neighborhood. It is much harder to be safe and alert of weather conditions without Wi-Fi.

  • Peer to Peer or Server Based Networking

    2177 Words  | 5 Pages

    A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).

    Mesh networks are reliable, stable, and redundant. If a node can no longer operate, all the others are not affected as they can still communicate either directly or through one or more intermediate nodes. Mesh networks can be very expensive due to the large amount of cable and connections required. Bus Topology Bus topology refers to a local area network (LAN) arrangement where each node or device is connected to a main cable or link called a bus. The bus network is simple yet very reliable.
