Ethernet Research Papers Samples For Students

EXECUTIVE SUMMARY

Ethernet has been termed as the most ubiquitous networking interface in the world. Almost all traffic passes through multiple Ethernet links. The point is that majority of the Ethernet links spend time while idle waiting between packets of data transfer, but consuming power at a near constant rate. In fact, on average, 10% of all IT power is consumed by network devices and network interfaces translating to tens of TeraWatts hour per year. A solution lies in the design of green networks which consume minimal power while idle without losing their functionality. In this research paper, Energy Efficient Ethernet is ...

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 ...

The Top-Down Approach

Network Architecture and Design:
The Top-Down Approach

Network architecture and design are many times two separate stages in a network implementation project. McCabe (2007) identifies network architecture as a higher level concept of a network. He says that it focuses on more general relationships between the major components of a network. For example, "addressing and routing, network management, performance, and security." (p. 211). The design stage of the project normally starts after the higher level architectural plan has been approved. This is where the real detailed work starts and the nuts and bolts start to come together.
In designing your network, ...

People work from the comfort of their homes at any time of the day and night possible through improved internet connectivity thanks to technologies such as fiber optics. The paper will review some of the current fiber optic ...

IT133 – Week 3 Assignment

IT133 – Week 3 Assignment
4B/5B is a block encoding system that breaks up long strings of zeroes and ones but does not increase the frequency bandwidth by breaking them up in four-bit sequence. Table 1 shows each block of four bits replaced by a block of five bits. Due to this, there cannot be more than one leading zero and two trailing zeros. This means that the resulting bit stream has no more than three consecutive zeros (Figure 1). This bit stream is transmitted using non-return to zero inverted (NRZI) method and is used in 100BaseTX (Fast Ethernet) networks ...

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 ...

Introduction

There is much technological advancement in the modern times that could greatly affect the daily lives of the people. One of these brilliant inventions is the Wi-Fi. Wi-Fi is a technology that could be used to connect the devices into the internet or into a wireless Local Area Network (LAN) (Katz, 2006). With this technology, changing information and data could become more mobile since people would not need cables and connectors to connect the devices into a network. Wi-Fi accelerated the technological advancement of exchanging data and accessing to the internet. It is not easy imagining life in the modern times without ...

Introduction

ADSL (Asymmetric Digital Subscriber Line) is a modem technology that is available channel bandwidth is shared between the outgoing and incoming traffic is asymmetric. Since most users have incoming traffic volume is much higher than the volume of outgoing, the rate of outgoing traffic is significantly lower. This restriction was uncomfortable with the spread of peer-to-peer networks and video.

History of development

History of the development of ADSL technology started in the second half of the eighties, when were searching technology for interactive television. Pioneer family of technologies xDSL is a company Bellcore; in 1987, it introduced the first specification of a family of technologies ...

Network Test Equipment

Every computer network is distinctive and is prone to various challenges, which may help to guarantee the correct transmission today and tomorrow. It is critical for the network administrator to analyse the network hardware equipments and network software to obtain a sense for smooth transmission, often called a baseline. In the instance that errors occur, the network administrator may be competent enough to determine from the indicator lights or by using network test equipments where the source of the transmission error originates. For instance, the network administrator would effortlessly recognize if indicator lights were out that are supposed to be on. ...

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 ...

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 ...

Research paper

Permanent control over the work of local network, which is a fundamental of any corporate network, is needed to maintain it in working condition. Control - a necessary first step that must be done in the management of the network. Given the importance of this function, it is often separated from other functions of management systems and implemented by special means. Such division of control functions and actually management is useful for small and medium-sized networks, for which the installation of the integrated management system is not economically sensible. The use of autonomous means of control helps the network administrator to ...

Network security is a means to assure that unauthorized access to assets in the network is prevented. This is vital if we have to protect the CIA triad of Information security, which is to protect the Confidentiality, Integrity and Availability of the data. Unauthorized access could violate one of more of the CIA triad’s principals. These unauthorized accesses also cause loss of accountability and nonrepudiation of actions. This paper examines the concepts of Network Security ...
