P1: Describe Network Technologies:
Network Operating systems: A Network operating system is the software, which runs on the server. It allows the server to control functions within a network. This could include users, groups and security. Some examples of these operating systems are Windows, Linux and Mac OS.
Network protocols SNMPv3 and ICMP: SNMPv3 is an Internet standard protocol, which manages devices on IP Networks. SNMPv3 is supported by routers and switches. The main difference between SNMPv3 and SNMPv2 is better security. It adds cryptographic security and more encoded security parameters. ICMP is used to send error messages when a service isn’t available. One command, which uses ICMP, is the Ping command, which is used to test connection …show more content…

The main topologies are Bus (All Workstations are connected to one line), Star (All Workstations are connected to a central hub), Ring (All workstations are connected to fellow workstations left and right of them) and Mesh (All workstations are connected to each other). A lot of topologies are designed to allow more workstations to be added at a later date. But a lot of topologies also have weaknesses, such as the Bus topology and the Ring topology, which would both break down if a node was to fail.
Network Devices: Network devices include all devices, which help make a network workable. These include Hubs (Enables more than one computer to interconnect on a network), Routers (Connects two networks), Switch (Joins multiple computers within one LAN and a Bridge (Allows one network to connect to another …show more content…

It allows network administrators to create a virtual server environment by using some of the server’s resources. By doing this, it creates virtual/private servers and one of the benefits of this is that it would cost less money to use virtual servers rather than physical servers as hardware maintenance would not be required. Also, if one virtual server goes down, the others will still be left running. In the example above, there are 4 physical servers. Server Virtualization only needs one physical server to be able to create the virtual servers.
Video on Demand: Video on demand has already had a huge impact but it will continue to grow. The more shows they manage to get for video on demand, the more people will possibly sign up. There are already millions of people who use Netflix all around the world and with it coming to more devices (Including game consoles like PS4 and the Xbox One) video on demand is one of the biggest emerging technologies out there
