VLAN IT/242 VLAN Virtual Local Area Networks (VLAN) are beneficial because they improve security and bandwidth consumption. The call center has expanded taking up space on other floors causing part of the Engineering department and the Operations department to move offsite. All of the departments still need to be connected so that their data is still accessible to each other despite the expansion. A VLAN will allow these employees to continue to connectivity with their groups and

Week 4 INDP NTC/362 INDP‚ Part 3 Local Area Networks (LANs) connect multiple computers that in a geographically limited area‚ this can be within the same room or building‚ to share information and resources. A LAN enables devices to communicate over a network with one another internally‚ otherwise known as an intranet. Each Kudler location would represent a LAN since each location has an internal network that is sharing local resources. The majority of LANs are connected using cables with copper

commercial release‚ Ethernet has retained a good degree of compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols. Ethernet is a family of computer networking technologies for local area networks‚ known as LANs. Ethernet was commercially introduced in 1980 and standardized in 1985. Ethernet has largely replaced competing wired LAN technologies such as a token. The Ethernet standards comprise several wiring and signalling variants

Beowulf Clusters Beowulf clusters were created in the early 1990s by two NASA employee’s‚ Donald Becker‚ and Thomas Sterling‚ to serve their computational needs. They did this by connecting multiple personal computers on a local network that ran on free open source software. This cluster of interconnected computers allowed them to solve task that normally only a supercomputer could perform. Beowulf clusters yield supercomputer performance at a fraction of the cost. They are relatively inexpensive

There are a lot of problems identified before installing the new computer system that was created‚ some of which include; when the management decided to upgrade the AIS‚ they installed a mainframe at headquarters and local area networks at each sales office. The IS manager and four system analysts were hired shortly before they integrated the new computer and the existing AIS. Another problem was that top management formulated all plans and directed all operations. Data
