Is the internet a useful tool for high school students? There are positive aspects as well as negative on which the Internet is useful or not‚ but what I believe is that the Internet is a useful tool for high school students. A few reasons why is that the Internet is more convenient‚ it’s an easier source‚ and it’s a lot faster. The Internet can be used pretty much almost anywhere. Searching through books in a library will take a longer time than just using the Internet‚ if time is a concerned matter

Open System Interconnection‚ model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next‚ starting at the application layer in one station‚ and proceeding to the bottom layer‚ over the channel to the next station and back up the hierarchy. The OSI model is not a real network architecture‚ because it does not really specify the services and protocols each layer should use. It rather describes what the layers must do. Nevertheless‚ the

networks. For example‚ you can install a network-based firewall on the edge of your private network that connects to the Internet to protect against attacks from Internet hosts. * A host-based firewall inspects traffic received by a host. Use a host-based firewall to protect against attacks when there is no network-based firewall‚ such as when you connect to the Internet from a public location. * Firewalls use filtering rules‚ sometimes called access control lists (ACLs)‚ to identify allowed

each layer has a job to do I was wondering which of these layers would be most important in developing security protocols for my company? Since no one else answered this one I thought I would take a stab at what I would say to my “potential client” if I was asked this very legitimate question during my hypothetical meeting. Here goes: When it comes to developing security protocols for your organization the OSI model will play a critical role in determining what risks are present to each area
