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.

Advantages and disadvantages of local area network (LAN)

Before going into the main topic let me first discuss what is LAN. LAN is a short form of local area network. Local area network is a network for connecting computers and other computer accessories with each other. Computer accessories include printers, scanners, game consoles etc. LAN is used to make the connection of computers within one building. To make the connection between the computers we use communication devices and cables. Communication devices are hubs, switches, and routers.

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? What is WAN? What is MAN?

When a Network connected to a limited number of computers or systems within a small geographical area is called the local area network. We have different topologies to administrate the structure of the local area network. Let us discuss each type of topology in detail. The local area network connects arranged in the different topologies. Ring, star, and bus topologies are used for the arrangement of the local area network. All the computers and systems are connected in a closed-loop called the Ring topology.

1. Resource Sharing. Sharing of resources such as hard disk drives, DVD drives and Printers are made easy in Local Area Network. · 2. Software.

 Сьюзан, это же абсолютно ясно. Танкадо выгравировал ключ Цифровой крепости на кольце. Золото долговечно. Что бы он ни делал - спал, стоял под душем, ел, - ключ всегда при нем, в любую минуту готовый для опубликования. - На пальце? - усомнилась Сьюзан.  - У всех на виду.

Как только Танкадо узнает о том, что вы сделали, он опубликует свою копию, и рынок рухнет. - Вы получите оба экземпляра, - прозвучал голос.  - Мой и мистера Танкадо. Нуматака закрыл трубку ладонью и громко засмеялся. Однако он не смог удержаться от вопроса: - Сколько же вы хотите за оба экземпляра.

Чего вы хотите. - Я из отдела испанской полиции по надзору за иностранными туристами. В вашем номере проститутка. Немец нервно посмотрел на дверь в ванную. Он явно колебался.

Сьюзан прочитала открывшееся сообщение, которое состояло из одной строчки, потом прочитала его еще. ПООБЕДАЕМ У АЛЬФРЕДА. В 8 ВЕЧЕРА.

ТРАНСТЕКСТ, подобно всем великим технологическим достижениям, появился на свет в силу необходимости. В 1980-е годы АНБ стало свидетелем революции в сфере телекоммуникаций, которой было суждено навсегда изменить весь мир разведывательной деятельности, - имеется в виду широкая доступность Интернета, а если говорить конкретнее - появление электронной почты. Преступники, террористы и шпионы, которым надоело прослушивание их телефонов, с радостью встретили это новое средство глобальной коммуникации. Электронная почта соединила безопасность обычной почты со скоростью телефонной связи.

Хотя большинство отделов АНБ работали в полном составе семь дней в неделю, по субботам в шифровалке было тихо. По своей природе математики-криптографы - неисправимые трудоголики, поэтому существовало неписаное правило, что по субботам они отдыхают, если только не случается нечто непредвиденное. Взломщики шифров были самым ценным достоянием АНБ, и никто не хотел, чтобы они сгорали на работе.

Мидж повернулась к нему на своем стуле. - Это не смешно, Чед. Заместитель директора только что солгал директорской канцелярии.

 Нет. По-испански говорила очень плохо. - Она не испанка? - спросил Беккер. - Нет. Думаю, англичанка.

Увы, теперь, несмотря на силу рук, он не мог подтянуться, чтобы влезть обратно. Плечи его отчаянно болели, а грубый камень не обеспечивал достаточного захвата и впивался в кончики пальцев подобно битому стеклу. Беккер понимал, что через несколько секунд его преследователь побежит назад и с верхних ступеней сразу же увидит вцепившиеся в карниз пальцы. Он зажмурился и начал подтягиваться, понимая, что только чудо спасет его от гибели. Пальцы совсем онемели.

Чатрукьяну была известна история ее создания. Несмотря на все предпринятые в конце 1970-х годов усилия министерства обороны сохранить Интернет для себя, этот инструмент оказался настолько соблазнительным, что не мог не привлечь к себе внимания всего общества. Со временем им заинтересовались университеты, а вскоре после этого появились и коммерческие серверы. Шлюзы открылись - в Интернет хлынула публика. К началу 1990-х годов некогда тщательно охраняемый правительством Интернет превратился в перенаселенное пространство, заполненное общедоступными почтовыми серверами и порнографическими сайтами.

Сьюзан на секунду задумалась. - ARA обслуживает в основном американских клиентов. Вы полагаете, что Северная Дакота может быть где-то .
