Protocol numbers are used to configure firewalls‚ routers‚ and proxy servers. In Internet Protocol version 4 (IPv4‚ Request for Comments [RFC] 791I)‚ the protocol number can be found in the Protocol field of an IP header.ICMP Echos are used mostly for troubleshooting. When there are 2 hosts which have communication problems‚ a few simple ICMP Echo requests will show if the 2 hosts have their TCP/IP stacks configured correctly and if there are any problems with the routes packets are taking in order

What are the pros and cons of the Kyoto Protocol? Do you think it should be followed? Why‚ or why not? Kyoto Protocol was signed in 1997 in Kyoto‚ Japan‚ with the aim to reduce greenhouse gases emission and thus to conquer global warming. It came into force eventually on February 16‚ 2005 with 55 countries ratifying it. Apparently the effect of such agreement is distinctive in different states depending on the level of the emissions they have. Numerous supporters of the Protocol’s promotion

OSI Layers 1) Physical Layer: The physical layer is at the bottom of this model. It deals with crude data that is in the form of electrical signals. The data bits are sent as 0s and 1s. 0s correspond to low voltage signals and 1s correspond to high voltage signals. The mechanical aspects of communication‚ such as wires or connectors come under this layer. The physical layer also deals with how these wires‚ connectors‚ and voltage electrical signals work. Also‚ the process that is required for

The OSI model has seven layers‚ with each having different types of security responsibilities. The seven layers are application‚ presentation‚ session‚ transport‚ network‚ datalink and physical with control being passed down from layer to layer starting with application. The biggest threat to these layers is through people‚ sometimes known as the 8th layer of the OSI model. Companies should take the time to educate their employees on the security threats that each individual brings to the company
