LOCAL AREA NETWORK (LAN)
<>INTRODUCTION<>
Local Area Network is a computer network connecting computers within a small area or places. LAN size is limited to a few kilometres. More than one LAN can be connected to one another by using telephone lines or through radio waves. LAN has higher data transfer rates.
LAN is built in with inexpensive hardware such as Ethernet cables, network adapters and hubs. Special operating system is also be used to configure LAN. Microsoft Windows provide software package called Internet Connection Sharing(ICS) that support controlled access to LAN resources. IP “class A” LAN can accommodate more than 16 million devices organized into subnets.
LAN are distinguished from others type of networks by its transmission media and topology. Common topology used by LAN is ring, star and bus topology.
LAN party – Is a multiplayer gaming event where participants will bring their own computers and build temporary LAN.
Example: A small LAN can have exactly two computers.
A large LAN can accommodate thousands of computers.
LAN divided into logical groups called subnets.
LAN is divided by two: wired LAN and wireless LAN.
The differences in terms of: - the medium impacts the design.
- stations are mobile.
- different MAC.
- wireless LAN is cheaper to install and maintain.

Example of LAN technologies are Ethernet, Token Ring and FDDI.
LAN has high performance designed to satisfy requirements of both closely knit multi-computer systems and communities of users spread across large campus area.
LAN has limited area because of it small coverage. The area is including home, school, computer laboratory or office building.
LAN can handle so much traffic but it will starts to slow down for temporarily.
LAN have a lot of advantages that makes it good enough as a network even though it coverage is just within a small area or place.

The Unistep IRP Elexol EtherIO 24 Module is a network board that is integrated with features that allow multiple devices over the same network to communicate. This microcontroller was designed to be implemented as an addition to a larger network system; the multiple features and capabilities allow for various industrial and home applications. Ethernet is very common and used in most networks, which makes the IRP a great candidate for networking problems both at home and in the work field.
... access to what and in which sequence. The router connects the LAN to other networks, which could be the Internet or another corporate network so that the LAN can exchange information with networks external to it. The most common LAN operating systems are Windows, Linux, and Novell. Each of these network operating systems supports TCP/IP as their default networking protocol. Ethernet is the dominant LAN standard at the physical network level, specifying the physical medium to carry signals between computers, access control rules, and a standardized set of bits used to carry data over the system. Originally, Ethernet supported a data transfer rate of 10 megabits per second (Mbps). Newer versions, such as Fast Ethernet and Gigabit Ethernet, support data transfer rates of 100 Mbps and 1 gigabits per second (Gbps), respectively, and are used in network backbones.
There multiple LAN standards because there might be wide range of data rate and transmission that might need to support. For that reason there are a set of standard that are developed by IEEE 802 committee which are accepted and used by most of the product in the market today. Some may use the standard for Token ring, Ethernet and Wireless.
Perhaps the most redundant, fault-tolerant of all network topologies is the mesh LAN. Each node is connected to every other node for a true point-to-point connection between every device on the network.
Not many great novels were produced during the post World War II era. Perhaps the greatest novel published was J. D. Salinger’s The Catcher in the Rye. This book, just like all other great works, was met by scathing criticism and unyielding praise. Many literary critics marveled at Salinger’s genius use of language to make Holden Caulfield, the main character, unbelievably realistic. Through Holden’s thoughts and dialogues, Salinger successfully created a teenage boy. Because of that The Catcher in the Rye became one of the few great post World War II works.
In order to ensure that the most appropriate and detailed evaluation of these platforms are analyzed and presented so that their feasibility can be determined either for a comprehensive rollout, or for specific requirements that have been identified. Three specific vendors have been identified, all of whom have a vast experience with the implementation of Linux solutions and can also be defined as some of the leading names within the market. Each of these vendors offerings in both a Server and Workstation configuration will be appraised in order to determine the most efficient and effective solution which could be implemented.
The creation of the internet has truly changed the world in drastic ways. However, his change is directly influenced by huge companies that provide data. Net neutrality is the principle that all internet data providers should treat data the same and not discriminate against a certain person, website or company. Under these rules, internet providers can’t block, censor, or slow down certain data. Recently though, many companies have been fighting the repeal of net neutrality. I believe that net neutrality is important for the stability of the internet and the companies that rely heavily on the internet to spread their ideas, products and information.
Why should we be worried about the open internet? In the early 1990’s modern internet was introduced. After the increase in traffic flow (internet use) many large IPS (Internet Service Providers) were caught slowing data from popular websites to thousands of US businesses and residential customers in dozens of cities across the country. As a result, the Obama administration insisted on new Net Neutrality rules, meaning IPS’s could not block different websites or apps, slowing of services, or no discrimination amongst companies, which is causing many debates and concerns. Net Neutrality is the guiding principles for an open internet. The freedom of the web is in danger, and as the consumers we must preserve the freedom of the open internet. Substantial Internet Service Suppliers are attempting to hinder the internet and raise charges for Americans to use the web and only the American consumers can restrict them from having complete control. Without net neutrality the open internet could fall into the
I attend James Hargest College, a co-educational institution, situated in Invercargill, and composed of two campus sites. James Hargest College boasts a role of approximately two-thousand students and two-hundred staff members. Both grounds of James Hargest College have access to multiple network drives. A network drive, located on a server, is a storage device on a local area network (LAN) within a home or business. A network drive makes it easier to share documents, hardware, programmes and files within the LAN, between computers.
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).

Mesh networks are reliable, stable, and redundant. If a node can no longer operate, all the others are not affected as they can still communicate either directly or through one or more intermediate nodes. Mesh networks can be very expensive due to the large amount of cable and connections required. Bus Topology Bus topology refers to a local area network (LAN) arrangement where each node or device is connected to a main cable or link called a bus. The bus network is simple yet very reliable.
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.
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
