Essays on LAN

Abstract

Computer networks are a group of computers that are connected to work together in sharing information and data. Usually, various computer network types are categorized using their scale and scope. About all design types are referred to as a type of area network by the networking industry (Lowe, 2009). Commonly known area networks types are; Metropolitan Area Network (MAN), Wireless Local Area Network (WLAN), Wide Area Network (WAN), Local Area Network (LAN), Personal Area Network (PAN), Cluster Area Network (CAN) and Storage Area Network (SAN). WAN and LAN is the most common types as they are the primary categories ( ...

The warehouse employees are not able to communicate to main office employees through the internet since their machines are not the ...

DESIGN PROPOSAL

1.0 PHYSICAL NETWORK DESIGN This design implementation must be on LAN systems because it is located in within the same building that has no structured facilities that aid data transfer from one network to another. Use of proper network topology helps in structuring the network with advantages such as cost reduction and less power consumption. The network nodes and connection lines are supposed to be designed in such a way that it reduces complexity and utilizes the available space properly. Currently, there are both physical and logical network topologies [3]. The physical aspect is defined as the actual geometric ...

CSMA-CD is not used in wireless because it cannot detect whether a collision occurred or not, therefore, it will be of no use. 2.0 Price and performance Considering the fact that about 100 employees will be connected to the network, I would recommend the use of wired network because wired LAN offers superior performance as compared to wireless LAN. It is prudent to use Ethernet switches since they are cheaper and also utilizes the available bandwidth. Ethernet switches are relatively cheaper than hubs hence most recommended (Laude, 2002). It is also important to note that hubs may suffer performance ...

Introduction

Active directory (AD) is a windows domain network or Network Operating (NOS) directory mainly designed for windows server 2003 and windows 2000. Active directory therefore is directory service, which catalog information stored in an organized manner allowing access to information in the directory matching their values and names. For example, a user trying to log into a computer in a client computer in the server domain of the network, active network aid access by verifying the back end user by matching a user password and the directory domain thereby determines whether you are a system administrator or a regular ...

The types of Networks

A computer network describes a collection of computers and other devices. These computers and devices are interconnected by channels of communication which allow for the sharing of information and resources among the said devices that are interconnected. The classification of networks follows different characteristics such as the medium used for the transportation of data, the protocols of communication used, scale, topology, and the scope of an organization as stated by Akyildiz & Rudin (2013). The categories of networks, therefore, constitute; a local area network, a Wide Area Network, a Metropolitan Area Network, Wireless Local Area Network, System Area Network, and ...

Part 1: Once physical access is obtained by an intruder all security is lost is true because physical access provides an entry even to a reasonable expert to hack and gain access to the network, unencrypted terminals and servers. Wireless networks have not completely decreased the need for hackers to gain physical intrusion as there are vulnerabilities as similar to the wired networks. The systems are exposed to negative forces due to the lack of proper safeguards, as in the case of wireless LANs . Comparing wireless vs. wired security, it is vital to secure a wireless network than to ...

Communication System

The key elements of a data communication system are the source, the transmitter, the transmission system, the receiver and the destination. The source will be used in the generation of the data to be transmitted. The transmitter has a purpose of transforming and encoding the data into signals that can be transmittable for example the transformation from a digital bit stream to the corresponding analogue signal. The transmission system serves the purpose of carrying the data and it can be in terms of a transmission line or a complex network connecting the source and the destination. The receiver will ...

A work like Pearl S Buck’s The Good Earth is by its very nature orientalist in the Saidian sense Because it was created within the structures of Orientalism as both a genre and as an epistemological category. Buck was born the child of an American missionary in China and spent much of her formative years there. Buck’s early life and experiences as an American and the child of a missionary informed her preconceptions of China, its people, society, and culture. Orientalism in this sense isn’t just a literary genre: an orientalist work is not just, a ...

What purpose do financial ratios serve? Why would anyone look at a ratio when analyzing a company? After all, it’s just a number. Actually, financial ratios do serve a purpose. A big purpose actually. By themselves, they don’t tell us much. But when compared against other companies and the industry as a whole, they are very valuable. But we have to remember not all industries are the same. Capital intensive industries like energy are much different than healthcare. What may be a good ratio in one may not be in another. So what can a ration tell ...

The network that makes email communication possible consists of infrastructure based on modems switches and routers. Based on the topology of the network a modem will be used to connect the Local Area Network (LAN) to the Wide Area Network (WAN) connection to facilitate encoding and decoding of digital to analog signals. A router will be connected to the modem to direct traffic between the LAN and the WAN connection enabling the network to be a part of the internet. Switches are also connected to the router serving as a hub for the connection of the different devices used ...

IEEE 802.1X Standard and EAP Authentication Schemes

Abstract Authentication risks are common reasons why network users are left frustrated when attackers exploit vulnerabilities. With increasing number of network attackers, there is a necessity for reliance on authentication technologies that offer the greatest efficiency in terms of denying access to unauthorized users. IEEE 802.1X and Extensible Authentication Protocol play a major part in mitigating authentication risks including providing a framework for handling issues such as changing of password by attackers, strong credentials in unprotected networks and the risk of re-using a single password for a longer-than-safe duration.
