Main Types Of A Network

This allows you to share centrally stored files to all of your connected computers easily. It also makes sharing a printer much easier than transfering everything to one computer as a gateway.

It is in most cases used to connect multiple local area networks together to form a bigger network.

Repeaters are devices for amplifying signals and retransmit at higher power on the area of an obstruction for the indication to cover longer detachments. They are used to in the

HUB - An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment.

Bridges are networking devices that can connect 2 local area networks (LAN). A bridge can learn all of the MAC addresses on the network, and this is done during the bridges data gathering phase. Basically a bridge will receive the data and analyze the address. The bridge will then pass the data on to the correct address. The ports on a bridge are in and out, but they are smart ports with the ability to locate the address on the network.

The mesh topology provides multiple routes between devices. Not only does this provide alternates for file transmission should there be a failure anywhere along the network, but it makes it easy for additional devices to be connected and will not slow down network traffic. Since networks built using mesh topology can be large one of the main disadvantages is the difficulty involved with installation, configuration as well as the on-going maintenance involved. The expense of cabling is also a disadvantage of mesh topologies as they can take more cabling and more devices than other topologies. (Networking

Team “C” was hired by Riordan Manufacturing management to overhaul the security features currently employed by the company. Management outlined a comprehensive plan that included a complete hardware refresh, security best practices and end user training. Team “C” will devote resources to assess the physical and network security issues and concerns at each Riordan plant. Once those have been identified, Team “C” will identify the data security issues and concerns present at each Riordan plant. Finally, Team “C” will address web security issues and concerns present at each Riordan plant and recommend a way forward for the company.

Legacy Ethernet is half-duplex, meaning information can move in only one direction at a time. In a totally switched network, nodes only communicate with the switch and never directly with each other. Switched networks also employ either twisted pair or fiber optic cabling, both of which use separate conductors for sending and receiving data. In this type of environment, Ethernet stations can forgo the collision detection process and transmit at will, since they are the only potential devices that can access the medium. This allows end stations to transmit to the switch at the same time that the switch transmits to them, achieving a collision-free environment. (Pidgeon, 2011)

Star – All computers and devices are connected to a centrally situated hub or switch. The hub or switch collects and distributes the flow of knowledge at intervals the network. It’s higher to use a switch than a hub as a result of a switch transmits the info to the supposed recipient instead of to all or any hosts on a network.

4. Radio: most common form of wireless transmission, typical of home routers and most wireless devices to use this form. Infared uses low frequency light waves to carry data using line-of-sight.

layer 1 | Hubs, repeaters, network adapters, Parallel SCSI buses. Various physical-layer Ethernet incorporates both this layer and the data-link layer. Token ring, FDDI, and IEEE 802.11. | - |

There are hybrid switches available today that combine both store-and-forward and cut-through switching methods. These hybrids are known as runtless or fragment-free switches. Fragment-free switches were designed to solve the late-collision problem and are primarily used in the backbone of congested networks. These hybrids check both the source and destination MAC address of a packet then make the appropriate switching to send the packet to its corresponding destination (Javvin Technologies,Inc., 2008).

LAN Switch- A LAN Switch performs the same work as a hub except that, a switch does not broadcast packets to every computer in the network like hubs. All the computers and computer devices will be connected to the switch by Ethernet cables. The LAN Switch costs $150.

• A hub and spoke network topology where many branch offices rely on connectivity to a centralized hub site for communications to other parts of the organization.

Twisted pair will also be used to plug computers to the main internet socket to aid the roaming of the wireless users.
