Access Control For Local Area Network Performance Essay

4)LAN (Local Area Network)-A LAN is a group of computers or devices connected together through a local network.LAN connections are usually very inexpensive.They are also usually very fast.LAN connections are usually within the same building.

A: LAN: LAN stands for Local Area Network. LAN is a network which cover a small area like colleges, schools or buildings.

In the early years of the internet, large scaled groups of computer were a bit of an issue, it was a pain to manage computers in respects to the communication between all the clients inside that group. Not only was it inevitable that businesses would require many more computers in their offices but it was also inevitable that the demand for this was going to increase both in and out of the work place. Initially the main driving at the time for Local area networking was so that people in the same

A LAN is a ‘Local Area Network’. It is a small network of computers most often

When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.

A LAN networks job is to link computers together through a central device. That central device is the router, it is what transfers data to and from computers with an Ethernet cable or wirelessly as long as you are connected to the network. When you connect to the internet you are actually connecting to millions of networks that are connect through a multitude of ways: telephone lines, cable, and even fiber optic lines. A LAN and the Internet are the same only in the way that they both need a router to, well, route traffic. You actually can incorporate the Internet access into a LAN. The modem must be connected to the router and then that will provide a gateway between the Internet and the network connection. A firewall is very important

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

LAN stands for Local Area Network. LAN is a type of network that interconnects computers and devices either wired or wireless and covers a greater distance. LAN is mainly used in private organisations such as college or university. More or less everyone uses wireless router at home these days and the user is able to connect between 5-10 devices wirelessly. The user can share the broadband or the connection with ADSL by using Ethernet cables. Smaller LANs can connect at least

LANs standards and protocols are Ethernet, IEEE 802.2 [IEEE 802.3, 100BaseT, Token Ring/IEEE 802.5 and FDDI.

The analysis of the problem should take a day. At the analysis stage we determine the solution. The solution has been identified as the installation of the access control system. At this stage the system parts are identified; they include input, output, communication devices, power supplies, detection devices, intelligent panels, card readers, lock hardware, the actions and the response of the system in case of violation of the input requirements or failure of the system.

For example, the Sales and Marketing Division has a desktop computer for each of the account representatives. All of these computers are connected to a small local area network (LAN) that serves only the Sales and Marketing Division. The

• Purpose of a LAN (hosts, devices (dual functions), examples of LAN use, types of resources shared, information that can be accessed using a LAN, purpose of LAN components) AND advantages and disadvantages of cable, fibre, wireless in terms of bandwidth, location, security, reliability, set up, suitability

As the use of computers, databases, and technology in general, security has grown to be a powerful tool that has to be used. The threat of outside sources intruding and exploiting crucial information is a threat that is present on a daily basis. As a part of creating and implementing a security policy, a user must consider access control. Access Control is a security tool that is used to control who can use or gain access to the protected technology. Access control security includes two levels; logical and physical. Though database intrusions can happen at any moment, access control provides another security barrier that is needed.

This is one of the crucial advantages of networking computers. Everyibe can find and share data because of networking. This is beneficial for large organizations to maintain their information in an
