LANs: Local Area Networks 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
Local Area Network A local Area Network (LAN) is a type of network typically used and connected in a small area, for instance, home, office, school or groups of building, in order to communicate with one another and share resource, such as printer or scanner. Those devices could be connected between each other by wired cable or wireless links, which is typically used as a standard LAN technology called IEEE 802.11. Usually, a local area network consists of computers and peripheral devices connected
Remote Control Software Used in a Local Area Network Introduction Remote control software can solve many of the problems that an administrator or user can encounter on a local area network. Using a remote-control program, one can access a PC remotely to exchange files between systems, run applications, take control of a client PC or server in order to troubleshoot a problem, and much more. Remote-control software is an application that you install on two PCs that permits one system (the guest)
Objective Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia area and using
Overview A wireless Local Area Network (LAN) is a moderate to high-speed flexible data communications system implemented as an extension to, or as an alternative for, a wired Local Area Network (Kolawole, 2014). In wireless LAN transmission making use of radio frequency to communicate over the air eliminates or at least minimizes the use of physically wired networks. From the beginning, IEEE 802.11 was designed to look and feel like IEEE 802 wired networks to include supporting all of the protocols
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

A network is a collection of entities that exchange information or good. Few examples of networks are nervous system, traffic light system, railway system etc. Computer Network is normally known as a system of interconnected computers & communication devices that can communicate with one another and share resources. At the most elementary level computer consist of two computers connected with each other by a cable to allow them to share data .A device connected to a network is called a node. A node
console, also known as terminal is a basic computer connected to another computer, server or mainframe. Its function is to maintain the status of the network or computer. In some programs, console allows developers or advanced user to access the special features to issue command by pressing the tilde key when the program running. In Local Area Network(LAN), Ethernet is a physical and data link layer technology. used to connect more than one computer systems to form LAN that comes with protocols that
sources and can affect different parts of a system and network. There are physical threats that can compromise a system and deny the use of network resources. Damage can occur on any piece of hardware connected to the system such as servers, routers, switches, and workstations/ PC’s. Access should be controlled to the location where vital hardware is stored. Ensure all doors remain locked and only authorized individuals enter restricted areas. There can also be damage caused by electrical threats
A network computer or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices transmit data to each other using data connections. These connections are established with nodes using either cable or through wireless media. The most famous and interesting computer network is the internet network. There are many types of computer networks, local area networks (LANs) to wide area networks (WAN) campus area networks ( containers
which is a computer on a network that performs important network functions for client computers, such as serving up Web pages, storing data, and storing the network operating system (and hence controlling the network). Server software such as Microsoft Windows Server, Linux, and Novell Open Enterprise Server are the most widely used network operating systems. As well the network operating system (NOS) routes, manages communications on the network, and coordinates network resources. It can reside
Information Communication Technology (ICT) have a huge impact on businesses nowadays, especially large scale organisations. Currently, Local Area Networks (LANs) are becoming more common in normal size businesses, and large-scale organisations tend to use Wide Area Networks (WANs), intranets and extranets. A LAN is a computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance
today is that they are unaware what of a computer network is. They might have heard of a computer network, but they are clueless as to how it works or why it works. People have basic questions that need to be answered. The goal of this paper is to give basic network information that will hopefully answer those questions. To give people an understanding about computer networks there are several areas that we must discuss. Definitions of some network nomenclature will be provided. Many people may have
from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world. Network Technology Overview The Ethernet has been around for several decades
Introduction This discussion will cover the technological progress that has been made as a society over the past decade, half century, and century, and will further discuss the origin of critical networks and cyber systems and how they have had a positive and negative influence on today's society. Lastly, it will explain emerging technologies that could possibly become critical assets tomorrow or in the generations to come. Discussion The difficulty in anticipating the evolution of technology is
Network Topologies Mesh Topology provides each node in a network with a dedicated connection to every other node. Advantages: Improves reliability through redundancy and fault tolerance - the ability of the network to continue operation despite the presence of hardware or software faults. Mesh networks work well when the nodes are located at scattered points that do not lie near a common line. The Internet was deliberately designed using a mesh topology to allow sites to communicate
the process of transmitting data in digital form by wire or radio. Digital data can be generated directly in a 1/0 binary code by a computer or can be produced from a voice or visual signal by a process called encoding. A data communications network is created by interconnecting a large number of information sources so that data can flow freely among them. The data may consist of a specific item of information, a group of such items, or computer instructions. Examples include a news item,
Existing network analysis in an important step when designing a new network as it establishes relevant information about the current network infrastructure and its bottlenecks. It is also a tool that helps to establish the needs and requirements of the company. Requirements of the networks in terms of the application and services are what drive the design of the network. This chapter reports on the outcome of the network analysis, giving details on the existing network design, hardware, protocols
LAN 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
