There are various types of computer networks available. We can categorize them according to their size as well as their purpose. The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. It includes devices housed in a single room to millions of devices spread across the world. What is LAN?

Not only LAN connects computers, it does the work of communicating devices such as routers, hubs and switches. It is no doubt that through LAN communication has made much more efficient. However LAN aren't flawless. LAN has certain pros and cons that you need to know before network installation. From this post, you know the pros and cons of using LAN network. Advantages of LAN. For an example all the resources can be connected to one single computer with a network so that whenever there is a need of resources it can be shared with the connected computers.
Another type of sharing made easy here is the Software sharing. A single computer with the licensed software can be shared among other users in the network. There is no need to purchase individual license for each and every computer in the network. All can be worked under one single license. Using LAN users can exchange messages and data in a convenient way. Since the data is placed on the server it can be accessed anytime by the LAN users.
Every single LAN user can do this with others on the network. Hence, this not only saves lots of time, it ensures that messages get delivered to the right people. As mentioned earlier data of the users are located at the centralized server. Any workstation in a particular network can be used to access this information. Moreover users can access their own set of data by logging into their respective accounts. Since data is stored on a local server, it can be guaranteed to be secure.
If the data on the server is updated then simply all the LAN users can access them. In addition to that, the host has the capability to deny or allow users in a particular network so that additional security measurements can be imposed. One single computer with an internet connection shares internet with all the connected computers. This type of infrastructure can be seen in Offices and Netcafes. This address will be normally used when sending and receiving data.
In modern computers these data is stored inside the network adapter that comes attached with the motherboard. Disadvantages of LAN. Even though LAN saves lots of money in terms of resource sharing, the initial cost involved in setting up the network is quite high. This is mainly due to the requirement of a special software that is needed to make a server. In addition to that purchasing of hardware equipments such as routers, hubs, switches and cables are required for the first time setup.
Since all the data of the connected computers are stored inside a central server, unauthorized users can view all the browsing history and downloads of all the connected computers. Therefore, this can lead to Policy violations. Since it is rather easy to gain access to programs and other types of data, security concerns are a big issue in LAN. The sole responsibility to stop unauthorized access is in the hands of LAN administrators.
The LAN administrator has to make sure that the centralized data is properly secured by implementing correct set of rules and privacy policies on the server. LAN often faces hardware problems and system failure. Hence, it requires a special administrator to look after these issues. The administrator needs to be well knowledgeable in the field of networking and needed at its full time job. LAN is usually made to cover up a limited distance up to 10km. Most probably it is operated in small areas such as in offices, banks and schools.
This is because its cabling system cannot be extended more than a certain range. Central server which is present on the LAN architecture manages all the attached computers. If in case the server encounters any faults all the connected computers are affected too. For an example if the files on the server gets corrupted, no more data on the attached computers can be accessible. Appearance of virus in a LAN based infrastructure is highly dangerous.
If one the attached computers are affected with a virus, it can easily spread to the remaining computers present on the network. No comments:. Newer Post Older Post Home.

Some computers can be more vulnerable than the other. Wifi is a mode of wireless technology which uses radio waves for its data transmission. Compared to the older Ethernet connections, Wifi pa The basic Local Area Network LAN is a type of network which connects computers of limited geographical range Probably within a building or a ho The Central Processing Unit also know as the Processor is considered to be the brain of the computer.
In fact it is the most active part The file is possibly corrupt is especially a common error experienced by the users when they try to install a new theme or a new operating Pages Home.

A computer network is a group of computers linked to each other that enables the computer to communicate with another computer and share their resources, data, and applications. A computer network can be categorized by their size. A computer network is mainly of four types :. It is a low range network. Extranet: An extranet is a communication network based on the internet protocol such as Transmission Control protocol and internet protocol.
Personal area network PAN is an interconnection between different devices like smartphone, tablet, computer and other digital devices. PAN is used for a personal purpose like data sharing among devices and it has a range of 10 meters. Some type of personal area networks is wired like USB while others are wireless like Bluetooth. Wireless personal area network is also known as WPAN. Personal area network does not require extra wire or space.
No extra space requires: Personal area network does not require extra wire or space. Connect to many devices at a time: Cost effective: Easy to use: Reliable: Secure: Used in office, conference, and meetings: Synchronize data between different devices.
In a typical local area network, a central file server provides services to each computer on the network. The server grants access to the network through authentication and shares resources such as files, folders and printers. When you don't have a file server, you can create a peer-to-peer network and share each computer's resources with all other computers. However, print sharing on peer-to-peer has some disadvantages related to energy consumption, productivity, printer installation and general peer-to-peer limitations. When a computer shares its printer over a peer-to-peer network, the computer and the printer need to be powered on for the printer to work.
A local area network LAN is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. Ethernet and Wi-Fi are the two most common technologies in use for local area networks. The increasing demand and usage of computers in universities and research labs in the late s generated the need to provide high-speed interconnections between computer systems. A report from the Lawrence Radiation Laboratory detailing the growth of their "Octopus" network gave a good indication of the situation.
Nowadays, more and more networks are operating without cables, within the wireless mode. Wireless LANs use high-frequency radio signals, infrared beams, or lasers to speak between the workstations, file servers, or hubs. Wireless LAN is formed by connecting different devices through wireless communication to form an area network. This network is straightforward to put in and use at the house or the other place.
Give us a call today to discuss how each can be optimized for your organization. Limited to Small Area. LAN connections can only operate in a local area which is usually not any bigger then a house, or a floor in an office building.
Cisco Network Templates. Public libraries and government agencies typically use a MAN. Computer hardware resources like printers, modems, DVD-Rom drives and hard disks can be shared with the help of local area networks. This will reduce cost of hardware purchases. Me aca5 at work. By running a large network connectedness, information can be disseminated more widely, rapidly and significantly. This is cheaper than buying a printer for every workstations.
