Bridge Analysis

Good Essays
In order for a computer to operate on a network, there is a range of different components that are required. They are the bridge, router, DSL modem, switch, network interface card and Hub.
A bridge is a hardware and software devices designed for bridging applications. Bridge start on the OSI Model Data Link Layer. Their function is to detect an error and control the flow on the physical link. They look for the MAC addresses for Ethernet and Token Ring to determine whether or not to forward or ignore a packet. The Purpose of a Bridge are isolating networks by Mac address, manages network traffic by filtering packets and translate from one protocol to another.
Hub is like a repeater. When a packet goes in one of the port, it gets duplicate inside

It operates a layer 2 of the OSL model because it requires a MAC address to send the packets. It is not suitable to be used as a host as it is usually connected to a hub. When a packet reached a bridge on one of port it will check if the destination MAC address is on the other port. If yes, the packet will be sent to the port.
A switch is similar to a bridge. But, it more efficient than a hub. For example, it has more than 2 ports. It does not have limitations that are on the hub and the bridge. It filters packets based on MAC address. It can manage a traffic better than a hub. It also more ports than a bridge to connect to many devices or a

It is not as popular as cat 3 and cat 5 cables as it is usually used for voice and low-speed data applications with a maximum speed of 16mpbs.
Third is the cat 5 cable. They are quite common for most people with a maximum speed of 100mbps.
Cat 5e cable was then introduced as higher speed was needed. It has a maximum speed of 1000mpbs. This has become the new replacement for the cat 5 cable.
However, all these cables are unreliable as they tend to be slow. More and more homes and company are starting to replace their normal UTP cables with fiber optical cables. These optical fiber cables are thin strands of glass the size of a human hair. They are more reliable and the doesn’t lose packets and they travel at the speed of light. (Explainthatstuff, 2016) stated that a single strand of optical fiber can carry approximately 25,000 telephone calls and a bundle of the optical fiber can carry a million calls.
Another type of network cable is the coaxial cable. It is mainly used by telephone companies to provide interference-free transmission electrical signals. It has a few layers of electrical conductors and insulator. This ensures that the signal is kept within the cable to prevent electrical noise from interfering with the signal. The inner layer is a conducting wire usually made of copper. This follows by an insulating material that surrounds the wire. Then a third layer of braided copper mesh that surround the 2 layer inside it, follow by another insulated

    The computer will then send a request to the server, the server responds and sends the data to the HTTP server. uses only one TCP connection from client to server there is no TCP connection from server to client. The default port for HTTP is TCP. HTTP prefers a reliable transfer instead of speed which is why it uses TCP. DNS uses UDP which is a faster way of getting the packets but not as reliable.…

    The objective of VLC is to increase data rates in wireless communication and to have better performance of networks especially for indoor networks using light emitting diode (LED) lamps [2]. LED, has many benefits such as low power consumption, small size, long life, low cost, low heat radiation. So they are used in numerous applications, like traffic lights, advertisement displays, and indoor lighting equipment and so on. LED based Li-Fi can provide internet connectivity to users instead of using existing wireless technologies as it has many advantages such as no electromagnetic interference, easy installation, high data rate, secure data communication and low cost [3]. Ceiling LED lights are used to transmit data to the users inside the…

    Along with the free PC-to-PC calls, calls that are from PC to landline are done for much cheaper than a traditional phone line (The Advantages and Disadvantages of VoIP). Another advantage is the portability of VoIP, a user is able to make a VoIP call from anywhere there is an Internet connection simply by logging into their account (The Advantages and Disadvantages of VoIP). This makes any business and its phone number and communications portable at any time. Along with this a user could travel with a VoIP device and plug into the Internet anywhere and make calls for nearly…

    When the sending device removes the message from the token, it changes the signal to indicate that the token is available and then sends the token along the network. Through this message, the workstations know that a message can now be sent. 15. How does a network card determine that a message is meant for a particular device? Each packet of data that is sent, contains the unique IP address of the workstation that the data is meant for.…

    Single-mode cables are much smaller than there multi-mode counterparts with a core diameter of approximately ten micro-meters. Single-mode has some advantages and disadvantages. The main advantage is that the single mode fiber has very low attenuation at larger distances. “Single-mode cable is capable of transmitting data at up to forty gigabytes at up to hundreds of kilometers with little integrity loss. Over greater distances, into the thousands of kilometers, this type of cable can send data at speeds up to ten gigabytes.” [2] Although this is a significant advantage, some of the disadvantages are drastic as well.…

    IBM 701 still used a vacuum tube circuitry but used magnetic memory storage and could hold a maximum of 2048 words. Although it was relatively cheaper compare to the ENAIC, it still cost $4000 at the time and $35000 adjusted for inflation. Transistor was the first major breakthrough for electronic computers as it was much smaller and consumes a lot less power compare to the vacuum tube. University of Manchester created the first transistorize computer in 1953, and by 1955, the computer had only 200 transistors and consumed 150 watts. Then the discovery of the semiconductor silicone took the transistor to the next level; thousands or millions of transistor can be pack on to a tiny chip, and as a result, the computer processing power increase exponentially by the year.…

    Optical Fibres By Jaydan Fibre optics are wires made of pure strands of glass or plastic spliced together (weaved together). These wires are as thin as strands of hair so their can be millions of them in a fibre optic cable. The wires are in bundles called optical cables and are used to transmit digital information over long distances. Fibre optics can be used for telecommunication, networking, decorations, endoscopy and much more because they are flexible, carry much more information than copper wires, can be used quickly by computers, the digital hardware is much smaller and it is easier to send information over long distances. Fibre Optic wires work by transmitting light signals through the core of the wire using total internal reflection…
