I. Physical Network Design

Introduction

A. Network Topology Business Needs In order to complete the needed full-time assignment efficiently and effectively, the University of Maryland University College will need a system in addition to tools to help the student attain their objectives. This entails new office space, a library, classrooms and computer labs will be able to achieve this capacity and optimize student learning potential

Proposed Topology

In order to plan for the facility of the network, I am proposing a star network topology for the facilities networking. This kind of network infrastructure is considered expensive due to numerous network devices that ...

Topology refers to the way in which computer networks are connected. It is the interconnection configuration that is responsible for providing effective communication. It involves connecting devices, arranging nodes and cables (Rouse, 2016). There are different types of network topologies, and each of them has specific tasks. In this paper, the differences between the topologies will be discussed.

Bus Topology

In this kind of topology, all devices are connected to a common shared cable. The name of the cable is a bus. Thus, there is a way in which all devices are directly connected to each other in the network. For ...

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 ...

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 ...

Abstract

In this article, a new bias current regulation circuit of a one-stage bipolar and Filed Effect Transistor amp is described. How the FET achieves high precision and simplicity by means of a combination of feedback error amplifier with a bandgap reference is explained.

Introduction

Regulating current through active devices sets the output level in a drive circuit. Figure 1. Below shows typical application of these active devices. Qo I used as a FET rather than a BJT. In a limiting amp, the Qo acts as a switch and the output signal level is proportional to the bias current. The gain ...
