Local Area Network Advantages Comprising a group of computers and/or mobile devices joined to a server, a local area network (LAN) helps businesses, schools and other organizations conduct daily operations. Setting up a secure and reliable local area network benefits not only you and your employees, but also your customers and business partners. Wireless Local Area Network - a LAN based on Wi-Fi wireless network technology. ADVANTAGES OF COMPUTER NETWORKS. DISADVANTAGES Security Concerns One of the major drawbacks of computer networks is the security issues that are involved. If a computer is a standalone computer, physical access becomes necessary for any kind of data theft.
Information. It is the one true universal currency we all carry with us every day. Thanks to how computer systems network together, we can share the information we have with others. We can gain new knowledge whenever we are connected. Whether it is a wired connection, Bluetooth, or a Wi-Fi link, computer networking has allowed us to have access to more information than ever before in human history.
Although there are many advantages to computer networking, there are disadvantages which must be considered as well. It creates a lifestyle which is dependent upon technology to gather the information we need to create the lives we want. If something goes wrong with the computer network, then we become isolated and this action could cause great harm to someone who is unprepared for it.
Here are some of the other advantages and disadvantages of computer networking to consider.
What Are the Advantages of Computer Networking?
1. People can share information freely.
Computer networking allows individuals and businesses to share information freely with one another. This information can be in several different formats. From files to emails, or blog posts to instant messaging, this process saves people time and monetary resources in the passing of information. Imagine the difference of sending a letter through a postal service to sending the same letter through email and that is the advantage a computer network provides.

2. It allows for frequent collaboration.
Computer networks allow multiple people to be logged into the same platform at once. They may be in several different locations around the world, but each person can log into their profile and access documents or files, at their convenience, to work on them. The modern computer network allows for global collaboration for teams of any size.

3. The cost of joining a computer network is going down.
In 1984, the cost of a Tandy 1000 was $1,200. This was one of the first PC clone computers that was intended to be a cost-effective solution for home computing and word processing. Although it did not have internet access, it did allow for computer networks to form. In 2017, the price of a Chromebook is less than $200 and does allow internet access and traditional computer networks.

4. Computer networking data can be stored off-line.
With the numerous threats to computer systems, the internet, and technology structures, there is a need to store information off-line to protect it from those who want it. Computer networks can be connected through the internet, via a virtual private network, or kept completely off-line to protect the system. The data collected, even if it is gathered online, can be stored off-line to protect it as well.

5. Anyone can connect to a computer network.
There is a minimal skill set required to connect to a modern computer network. If you know how to turn a computer on and then click on the appropriate prompts or shortcuts, then it is possible to join a computer network. The simplicity of joining makes it possible for even young children to begin taking advantage of the information access that computers provide.

6. Computer connections can be personalized.
The modern computer network isn’t an all-or-nothing system. Access authority can be included with a network so that individuals can access the specific information they need, but don’t need to sort through information they don’t need. This can enhance employer security, reduce the chances of fraud, while still providing tools that lead to increased productivity.

1. It requires a certain wealth to join a computer network.
In 2005, the International Telecommunications Union estimated that 51% of users in the developed world were connected to computer networks, but just 8% of users in the developing world could claim the same status. As of 2016, those figures have risen to 81% and 40% respectively. Although there have been increases to internet use and computer networking in the developing world, most people still lack consistent access to the information that is widely shared every day.

Although there have been increases to internet use and computer networking in the developing world, most people still lack consistent access to the information that is widely shared every day.
2. Disruptions can occur frequently.
Cyberattacks on computer networks in 2017, referred to as “ransomware,” allow a small group of individuals to affect the computer networking access of a society. By encrypting compute files for small ransom amounts, these attacks create a disruption to the networks that disrupt businesses and individual lives. Viruses and other forms of corruption can be equally disruptive. No computer network is 100% safe from these threats, so proactive interventions must be taken to preserve information access.

3. Computer networking can be addictive.
CNN reports that half of all teens in the United States feel like they are addicted to their phones. The average person checks their cell phone over 100 times per day. Being consistently connected to information and computer networks requires a commitment to consume the data that is provided. We have access to more data than ever before, but this also means we are taking less time to relax and unplug from our networks more than ever before. The American Psychological Association reports that 44% of US workers even check on work emails while on vacation.

4. Information availability isn’t always a good thing.
Online identity theft is one of the fastest growing crimes in the world today. In 2016, data on 15.4 million consumers was stolen to create losses of $16 billion. From 2010-2016, more than $100 billion in losses occurred. Since 2014, identity theft complaints have risen by 47%. The Insurance Information Institute reports that government documents and benefits fraud is the most common form of this data misuse. As computer networks continue to grow, the chances of having data compromised will grow at the same time.

5. There is little policing on a computer network.
Not all file sharing that occurs through computer networks is illegal. Piracy is a real threat to the well-being of numerous businesses and individuals. According to information provided by Freakonomics, the cost of online piracy for the economy is up to $250 billion per year. Direct losses in the US are above $8 billion, according to statistics provided by NBC News. Although some see it as a victimless crime, those that produce content and hold rights to it do not receive compensation from pirated sharing. Little policing is available on computer networks, however, and what is present is often focused on protecting the physical safety of others.

The advantages and disadvantages of computer networking show us that free-flowing information helps a society to grow. Assuming that proactive systems are developed and installed to counter the effects of the potential disadvantages, a computer network, at any level of connectivity, will help every society come closer to its full potential.

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).
Album xpress pro. 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.
