Cisco switches by default or configured in one VLAN. To configure the switch the Cisco serial connection is used through a terminal program like hyper terminal in order to get access to the command line interface. A VLAN is a switched network that is separated into parts by function, project team, or application regardless the [...]
Analyzing the seven layers of the OSI model, a conclusion to be made is that the layer three, also known as the network layer is the one that WAN protocols operate on. The network layer performs routing functions and identifies end-to-end addressing and routing datagrams. There is a unit called brouter that some layers contain [...]
Principles of Information Security Principle 1: No absolute security. This principle entails safe locks considerations (tamper resistant, but possible to be broken through), safe lock approach (an evaluation is given after testers get sufficient time and tools). Principle 2: Security goals are confidentiality, integrity and availability. Confidentiality only relates to authorized individual or systems. An [...]
The History and Purpose of the OSI Model The OSI model was developed by the International Standards Organization (ISO) to help people understand complex activities by using abstract descriptions. Even though officially it was created in the 80’s the OSI had its origins in the 70’s by Mike Canepa, with Charlie Bachman of Honeywell Information [...]

There are many components when you are dealing with building computer networks. Some of these components are wireless and some require wires to operate. On that same note, some also require other components to allow them to operate and some do not. The first component to be discussed will be a wireless router. A wireless [...]
