Computer Networking and Information Technology
« on: November 08, 2018, 10:36:42 PM »
Because networks play a central role in the operation of many companies, business computer networking topics tend to be closely associated with Information Technology. Networking trends that play a key role in IT include:

Network capacity and performance: The popularity of online video has greatly increased the demand for network bandwidth both on the Internet and on IT networks. New types of software applications that support richer graphics and deeper interaction with computers also tend to generate larger amounts of data and hence network traffic. Information technology teams must plan appropriately not just for their company's current needs but also this future growth.
Mobile and wireless usages: IT network administrators must now support a wide array of smartphones and tablets in addition to traditional PCs and workstations. IT environments tend to require high-performance wireless hotspots with roaming capability. In larger office buildings, deployments are carefully planned and tested to eliminate dead spots and signal interference.
Cloud services: Whereas IT shops in the past maintained their own server farms for hosting email and business databases, some have migrated to cloud computing environments where third-party hosting providers maintain the data. This change in computing model dramatically changes the patterns of traffic on a company network, but it also requires significant effort in training employees on this new breed of applications.
