1. INTRODUCTION
In the earlier stages of networking i.e, In lan, the initial physical locations of where the computers had to be positioned had to remain fixed throughout for further usage. Any changes in setting up of the host in a different location after the initial setup would lead to excess expenditure where new sets of cables had to be installed to establish a new connection. This lead to an increase in the cost of maintenance and the investment that was required to maintain a larger network which had a probability of growing day by day.
So the need for a vlan came into being where a large area network across the globe could be done at a lot more feasible price and the ever changing network can be easily maintained.
1.1 History of VLAN
The history of VLAN is very significant because the incentive to invent the technology governed the features built into the implementations. Increases in the number of hosts on the local area network and network applications have caused huge increase in the traffic of LANs. The increase in traffic caused congestion and collision problems. Due to this, the network managers used routers and hubs to separate their networks into many subnets with fewer hosts on each. Due to the broad flat switched networks there was increase in broadcast traffic which led the network managers to again divide the switched network so even broadcast traffic was limited to going to few unnecessary hosts as possible. The network managers wanted to do that while
4.1 The degree of global interconnection greatly increased after 1500 CE at which point it started to include the Americas, and parts of the world it had not before. BEfore this time period the globe was only connected in the eastern hemisphere and places were not as open and involved with one another everywhere. After this time period trade of materials, people, and crops became more prominent and new things were introduced to new areas, this was mainly due to the introduction of water based trade and the introduction of the Americas to the rest of the globalized world.
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
Users can plug their computers at the new locations and still be in the same VLAN. This is very hard when routers physically divide the network.
6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?
Task 1: Describe the data communication types used historically and the developments that have led to modern day Local Area Networks (LANs). Detail any emerging technologies and where you think data communications are likely to be in ten year’s time.
Network switches are deployed throughout the enterprise. They are used to distribute data and provide LAN connectivity to end users. Without the network switches, systems will not be able to communicate with servers and applications. All devices are managed. Managing network devices is critical to any organization. It allows
In the Future Corporation LAN, I have decided to some Virtual Area LAN Network (VLAN) for better performance, easier administration, less cost, and better security. There will be two VLANs for each department, total will be 26 VLANs. The first VLAN in each department will be only for the employees' department, and the second VLAN will be for the guests. I have decided to use static VLANs, so every port will be configured to be belong to a VLAN. I have selected static VLANs instead
VLANs or Virtual Local Area Networks are logical local area networks that extend beyond the traditional LAN architecture. Because a VLAN is a logical entity, creating and configuring a VLAN is done completely in software. The advantages to using this type of LAN include but are not limited to the ability to conserve the network resources, to bridge geographical drawbacks, and to better manage the movement of personnel and equipment. To understand the need for VLANs you must first understand the Local Area Network (LAN). The definition of a LAN started as a group of computers that were connected in the same area, but today’s LAN is defined as a single broadcast domain. This is explained easily by looking at a large organization where each department would be on a separate LAN found behind a router or switch. With today’s expanding networks it has become important for these
LANs, WANs and on the internet, and provide data storage independent of the location. ! !
The standardization of the network configuration enables your departments to work with common images and software that will lend itself a continuing ROI by reducing maintenance costs across all sites. A single maintenance plan will be effective at each site. All future upgrades can be rolled out quickly and in a cost-effective manner. Your IT professionals will be able employ best practices across the board without the worry of site specific hardware or software. Six Sigma practices implementation from the Sales Teams will be easily put in place.
These important factors of something to think about include such factors as the topology and placement of hosts within the network, the selection of hardware and software technologies for the network setup, and the careful setup of each part within the network in order to make sure that an effective system is developed linking all user departments and smaller companies (owned by larger companies) to the main office.
Before I dive into the significant developments within my life I feel it is important to look back at the broader scope of the history of telecommunications and technology to see some of the earlier examples of
Which of the following is a limitation of early networks that used a daisy-chain method of connecting
• 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
More and more applications that were used in the PC and laptop began to be used with the mobile. It was with the availability of internet with the mobile that made companies like Nokia look for platforms to deliver the service- including surfing and connecting to social media that prompted developers to begin developing programs for this segment. It was also this development that made Microsoft consider going into the mobile sector since the company had already established itself in the tablet segment.
