diagram illustrates a Local Area Network implemented using an Ethernet connection on a bus topology model. It is a LAN because there is no indication of considerable distance between the computers or departments. It is in Bus topology as since the computers connect to the network by connecting to the network cable. This as opposed to a star network topology setup.
Next to each network component is an Internet Protocol (IP) address. Each IP consists of four number whose value can range from 0 to 255. This four numbers are separated by period marks (WhatIsMyIPAddress.com, 2000-2016). No number can be repeated on the same LAN sharing the same subnet mask making it an effective way of uniquely ‘naming’ each component in the network.
Q1.Ethernet has become the standard for LAN communications. Give a brief overview of structure of an Ethernet frame.
Ethernet and Wi-Fi are the most commonly used technologies to set up Local Area Networks today. It operates by using Carrier Sense Multiple Access Detection (CSMA/CD) to control media access. (Study CCNA, 2016)
The structure of an Ethernet Frame is as follows:
The Ethernet Frame Structure (Anon., 2013)
• Preamble: This field is responsible for harmonizing bits…
a WAN network is an ISP (Internet Service Provider) (Ocens, 2012). This WAN connection is T1 that connects to the T1 Demarcation Router in the computer room; this terminates the T1 line and provides an Ethernet Connection to the Main Router as well as a T1 connection to the WAN. The main router creates LAN connectivity and connects to the PIX Firewall and the Ethernet Switch; the firewall controls access to the public internet through the main router’s connection to the WAN. The LAN connection…
This specifies the general interface between the network layer (IP etc.) and the Data Link layer (Ethernet, Token Ring etc.) It’s the standard for the upper Data Link layer sublayer, also known as the Logical Link Control layer. It’s responsible for flow and error control. The Data Link layer wants to send some data over the network, 802.2 LLC helps make this possible.
b. 802.3 – Ethernet
802.3 is the standard which Ethernet operates by. The original 802.3 standard is 10mbps. Commonly, Ethernet…
Technology Framework Design
In this section, we combine the user domain needs described in Part 1 of this proposal, the physical framework requirements described in Part 2, and the technology selections described in Part 3 to create the final Digital Edge Manufacturing network infrastructure proposal.
Choosing the Cabling Used in the Network
We considered infrastructure costs, speed, and reliability for cabling and adaptors. Our network employed hybrid type of network sine we use Ethernet cable,…
a Layer 2 protocol.
d. Leased lines are Layer 7 standards.
10. Which of the following statements is true when comparing the OSI and the TCP/IP model as defined in RFC 1122?
a. Two layer names match.
b. The lower four layers of TCP/IP define the same kinds of functions as the matching layer numbers from OSI.
c. The TCP/IP five-layer model is old and has been replaced by the seven-layer OSI model.
d. The TCP/IP application layer defines functions that match closely to only…
the student lobby. Network devices should be able to be secured and maintained with ease. The network devices should fit the needs of 524 potential hosts.
Proposed Network Devices
Switches in the closets and server rooms should be used over hubs. One 48 port switch is used for each classroom closet and server room. The computer lab uses a 72 port switch because of the number of hosts connected to it. Patch panels are also used for each closet and server room. More specifically, (2) 24 patch…
Communication is key, regardless of where you work. Communication can be between people or a computer communicating data to a person. When obtaining data from a computer, people want to be able to trust the data that they are receiving and that none of the packets got lost somewhere along the way. Packets are units of data that are routed between an origin and a destination on the Internet. Networks use Ethernet cables, called Category (more commonly referred to as CAT)…
it’s transmitted through copper which dwindles speeds; currently it is Fibre to the box then copper cable so you don’t get full fibre speeds.
What is LAN?
A Local Area Network or (LAN) allows a group of computers to associate with one another on the same network, such as; school’s, homes and offices. When on the same network, file sharing is quick and reliable because it’s dealing directly with another computer on that network. If many computers where on the same network it can also share…
gateway where the exterior close network is interrupted. Terminal are affixed to this gateway through point-to-point connections. In this action, the gateway behaves as a core switch. The simplest figures is when all data are digital and encapsulated into the equal protocol. For example, the gateway can be an Ethernet switch or an IP router. now, in residential zones, the best applied cabling manner is Twisted Pair Cable with RJ45 connector.
Home networks can conduct either…
