Jaagz is a small start-up shoe company. The company sells a variety of shoes for men, women, and children. It is located in the city of Los Angeles, California. Jaagz is situated within a single building and is spread among several floors. For this reason, Jaagz will require the use of a local area network. The local area network will be used to connect computers, printers, share files, connect to the Internet, etc.
The Jaagz’ local area network will use category 5 cable and run IEEE 802.3 protocol. Using IEEE 802.3, the network speed will average about 10 Mbps. It will utilize a combination of a star and bus topology, which is the most common topology used in networks. The bus topology makes up the backbone of the network while the star topology branches out.
A client/server system will be used by the

Jaagz company. The client/server system will allow for network management of multiple users as well as serve as a central point for database management, printing, communication, file sharing, information storage, and program execution. A server is a high-powered computer connected to the network that is accessible by all client computers on the network. Servers contain operating system software to manage the network. The client computers request various services from the server on the network. They also provide a user interface in addition to presenting all results to the end user. The client computers connect to the network via network interface cards. The device that will be used to connect the Jaagz’ local area network to the Internet is a router. Routers use data packets, which contain address information, along with a routing table to determine its intended destination. The routing table manages connection information, any priorities that may exist, and rules for handling network traffic. Routers also ensure any unnecessary packets do not use up all of the bandwidth. The Jaagz company will use a switch device to connect their computers together as part of a combination bus star topology network.
Switches use ports and sends information to a physical device address via these ports. They only send information to the particular computer that has the specific address and not to all of the computers.
The Jaagz company’s network will utilize a firewall. The firewall will be placed between the local area network and the Internet connection. Firewalls are put in place to prevent unauthorized access to a computer or network. A firewall will allow emails and web pages; however, it will block all other types of data.
In conclusion, a local area network is made up of computers and a myriad of devices, such as routers, servers, switches, and firewalls. In order for it to connect to the Internet, a router must be installed. Servers provide special functions such as printing, file sharing, etc. Switches connect the computers together from different parts of the network. Firewalls prevent unauthorized access. There are a host of other devices that may be used as well. These devices are hubs, gateways, repeaters, wireless access points,
etc.

Dodger was being sent off to Australia, he got caught for stealing. Fagin freaked out, he was thinking that Dodger would rat them out and it would be over for them. Soon after Fagin got the news, Monks showed up… He wanted Charley out of the room. He was about to tell him what Nancy did. Bill flipped out, thinking that she turned against him. He went to go find Nancy. On the way to find her, everyone got out of his way; nobody wanted his attention. He asked everyone if they have seen her and they all said “no.” Then, Bill found Nancy… Seconds later there was a loud scream. Everyone ran to see what happened and saw Nancy’s lifeless body with Bill running away. People chased after Bill, he went to Fagin’s place asking for money to get away.
It's important to gather information that is understandable by your students. The procces of gathering evendce in childrens learning can make a huge difference. there are many different kinds of assesments that help you as a teacher better educate your students. your lessons plans and what you teacer is very important to what they understand and how they learn.
This means that the punishment will take place in jails. Another key provision of AB 109
The moral philosophy best describes my personal decision making is virtue ethics (Ferrell, Fraedrich, & Ferrell, 2013). It best description of me as virtual ethics having exceptional moral character (Ferrell, Fraedrich, & Ferrell, 2013). My character displays honesty, integrity, and helpfulness (Ferrell, Fraedrich, & Ferrell, 2013). For example, a friend attempted to commit suicide as a result of a wife asking for a divorce through email (Ferrell, Fraedrich, & Ferrell, 2013). However, while working I received a phone call from him stating his desire not to live anymore (Ferrell, Fraedrich, & Ferrell, 2013). Meanwhile, I called his son to ensure that he wasn’t alone however, his son drove to the house and found his father sitting and with a
In order to have a greater understanding of the terminology and descriptions offered in this paper, we must first understand what a network switch is. A brief definition of a network switch is a computer networking device that connects network segments. It uses the logic of a Network bridge, but allows a physical and logical star topology. It is often used to replace network hubs. A switch is also often referred to as an intelligent hub.
Two routers demark the border between internet and intranet. Internal to these routers are two more routers, creating the appearance of a demilitarized zone (DMZ). However, there are access points, the wireless antenna system and the remote access server (RAS), that provide deeper intranet access that do not rely on the DMZ, rendering the latter rather decorative than substantial. Lastly, there is the virtual private network (VPN) that makes use of the edge routers and provides greater intranet access. Over all, there are four access points: VPN, two edge routers, the RAS, and the wireless system. The RAS, VPN, and wireless provide internal access.
The purpose of this papers it to examine in detail the operation of one of the wide area network that we discussed in class. This paper discusses the difference between frame relay networks and other point to point networks, advantages, addressing schemes, and different protocols supported. The paper will explain virtual circuits briefly before moving to its other characteristics because they are the key to understanding frame relay concept in general. Other than virtual circuits, we will see its addressing scheme, how frame relay guaranty bandwidth with its committed information rate and how to detect and avoid congestion.
Local Area Network or LAN, in computer science, a group of computers and other devices dispersed over a relatively limited area and connected by a communications link that enables any device to interact with any other on the network. LANs commonly include microcomputers and shared (often expensive) resources such as laser printers and large hard disks. Most (modern) LANs can support a wide variety of computers and other devices. Each device must use the proper physical and data-link protocols for the particular LAN, and all devices that want to communicate with each other on the LAN must use the same upper-level communications protocol. Although single LANs are geographically limited (to a department or an office building, for example), separate LANs can be connected to form larger networks. Similar LANs are linked by bridges, which act as transfer points between networks; dissimilar LANs are linked by gateways, which both transfer data and convert it according to the protocols used by the receiving network.

Over the last couple of years Network connection methods have been growing better and better so that the internet is easier to access and much more convenient. About 10 years ago it would have been hard to play games on the computer because of the speed of the connection and signals were received slower, But now days you don’t have to wait for a video to load or to receive a message from across the world. Below I have listed three different types of connections and explained their how they work.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
Among all the network topologies, Star topology is the main topic that will be discussed in the following report.
Many computer networks need a central computer which provides storage space and controls the network using special network software. This is known as a server. The other computers which access the server are called clients.
The Metropolitan Area Network requires a device called Routers for connecting each Local Area Network that involved.
