Advantages And Disadvantages Of Local Area Network Wireless Local Area Network Background The first wireless computer communication network ALOHAnet (operational in 1971) was developed by Norman Abramson, a professor at the University of Hawaii At first, the wireless LAN was so costly that it was just used as an alternative to the places where the cabling was difficult or impossible. Advantages of wireless local area network (WLAN): It’s a reliable sort of communication. As WLAN reduces physical wires so it’s a versatile way of communication. Iskysoft pdf editor download with crack. WLAN also reduces the value of ownership. It’s easier to feature or remove workstation. It provides high rate thanks to small area coverage.

Advantages of LAN (Local Area Network) The advantages of LAN are: Provides high-bandwidth communication. Transmission medium is inexpensive. Bandwidth is utilized effectively. Maintenance is easy. Disadvantages of LAN (Local Area Network) The disadvantages of LAN are: Speed reduces as it includes sharing of resources.
Local Area Networks (LANs) and Wide Area Networks (WANs) have much in common, but the differences are enough to make them two separate acronyms in speech and in practice. Each one has its benefits and downsides, and these advantages and disadvantages can affect an organization’s productivity significantly. Give us a call today to discuss how each can be optimized for your organization. So what exactly is the difference between a LAN connection and a WAN connection?
Local Area Networks (LANs)

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. Typically a LAN will consist of only a handful of clients, but can have upwards of a hundred.
One of the major advantages with LANs are the speeds they can reach. With a LAN, it isn’t uncommon to see technology ready for 1Gbps (1 gigabit per second). Example: If you were to download all 3 816 000 English articles off of Wikipedia it would take just over 13 hours to do so, where as a WAN would take 16 days to do the same. A LAN can operate up to 30x faster then a WAN
Another advantage to having a LAN connection is the cost. It is relatively cheap to have as it tends to require less hassle to set up and less advanced infrastructure to keep it running. This is mainly due to the technological components of a LAN, which brings me to the next difference.
A LAN connection tends to require some relatively simple things to set it up. All you need is some Ethernet cables, a network switch, and you are good to go. Alternatively, you can also see LANs being done over Wi-Fi, or you can use Wi-Fi in conjunction with standard Ethernet connections to create a LAN available to all kinds of devices, whether it be a smartphone or a desktop computer.
The major disadvantage with a LAN is inherent in its name. “Local” Area Networks are only good as far as you can reach an Ethernet cable or Wi-Fi signal. Simply put, you cannot buy an Ethernet cable that will reach throughout an entire building, and a Wi-Fi connection rapidly deteiorates as you get further then a few dozen meters away.
Wide Area Networks (WANs)

A WAN connection should truly only occur in large environments. WAN connections are available from house to house, city to city, and country to country. In fact, just by reading this you know you have access to a very popular WAN, the Internet. But what separates a WAN like the internet from a LAN?
Due to it's typically massive size, WAN's are almost always slower then a LAN. The further the distance, the slower the network.
One of the big disadvantages to having a WAN is the cost it can incur. Having a private WAN can be expensive. The reason that WANs cost a lot tends to be because of the technology required to connect two remote places, which brings me to the explanation of the technology behind a WAN.
A WAN connection is generally harder to set up, and there are many creative ways to do so. One very common way is renting a line from an internet service provider and using their network (that’s already connecting the nation and the world) and connecting your point A and B. Another way to do a WAN is connecting the devices with various wireless technologies, like cellphone towers or satellites. As you can imagine, all these are much harder to create than setting up a LAN and almost always demand high level professional setup and maintenance.
Trust Packetworks
Advanced networks can have LANs within LANs, LANs within WANs, WANs within WANs, and those can have their own sub networks, and those their own, and those their own. Let the professionals at Packetworks take over your next Networking project, to ensure it is down efficiently and effectively. A fast network allows for rapid transit of information, which leads to increased productivity, and increased customer satisfaction.
Ethernet is Local Area Network (LAN) technology. This system consists of rules to connect multiple systems on the LAN network connection. Apart from LAN, it is also used in Metropolitan Area Network (MAN) and Wide Area Network (WAN) network. A system for connecting a number of computer systems to form a local area network, with rules to control the flow of data and to avoid any error during the transmission by two or more systems. Robert Metcalfe invented Ethernet technology. It is standardized as IEEE 802.3
Ethernet operates at the link layer in TCP/IP model architecture. It offers connectionless communication and before transferring any data over the network, the system checks if the access medium is free to transfer data. It determines free medium using Carrier Sense Multiple Access/Collision Detection (CSMA/CD). Also, it is built on a star topology.
Ethernet uses two types of cables :
- Twisted pair.
- Fibre optic.
Basically it is characterised into three types of ethernet based on data transfer speed viz.
- Basic ethernet is slowest among all, which provide the speed of(about 10Mbps, 2500 meters).
- fast ethernet (about 100Mbps, 250 meters) which is intermediate between basic and Gigabit network.
- Gigabit ethernet (about 1Gbps, 250 meters).
Advantages of Ethernet :
- The fastest speed provide by Gigabit ethernet is of 1Gbps. The speed ranges from more than 10 times Fast Ethernet.
- To form an Ethernet, we don’t need much cost. It is relatively inexpensive. Total cost induced is less.
- In Ethernet, all the node have an equivalent privileges. It does not follow client-server architecture.
- It does not require any switches or hubs
- Maintenance and administration are simple.
- The cable wont to connect systems in ethernet is strong to noise.
- As it is strong to the noise, the standard of the info transfer doesn’t degrade. The data transfer quality is good.
- With latest versions such as gigabit ethernet and wireless ethernet (IEEE 802.11ac/11ad) transfer speeds in data with the speed of 1-100Gbps.
Disadvantages of Ethernet :
- It offers a nondeterministic service.
- It doesn’t hold good for real-time applications because it requires deterministic service.
- As priority packets cannot be set, it’s not suitable for a client-server architecture.
- In an interactive application, data is extremely small and wish quick data transfer. In ethernet, there’s a limit of the minimum size of the frame to 46B. As a result, it’s not an honest choice for interactive applications.
- If you’re using it for interactive applications, you’ve got to feed dummy data to form the frame size 46B which is mandatory.
- Not suitable for traffic-intensive applications. In case the rate of traffic on the Ethernet goes up the efficiency of the Ethernet goes down.
- It provides connectionless communication over the network.
- The receiver cannot able to send any knowledge after receiving the packets.
- If there’s any problem in ethernet, it’s difficult to troubleshoot what cable or node within the network causing an actual problem.
- The 100Base-T4 version does not support full-duplex data communication mode.
