A Drink of Technology for the Thirsty Mind
A computer network consists of two or more computers intended to share resources: A client/server network is a system where one or more computers called clients connect to a central computer named a server to share or use resources. Each client computer must use an operating system that allows it to be identified to participate in the network. Client/Server […]

Read moreTypes of Security In Part 1 of this series I mentioned WEP, SSID and MAC Address filtering as three methods of wireless networking security. Here we will get to know a little more about these and what other methods of security are available. WEP (Wired Equivalent Privacy) Developed in the late 1990s, WEP is a basic protocol that is sometimes […]
Read moreIn this article I will point out what sort of threats there are, give you some considerations when planning for the implementation of network security, and also a list of tips that will help to strengthen the security of your network.

Read moreWhat is IPv6? Before I get into all of the nitty gritty details regarding why IPv6 is a requirement, I want to talk briefly about what IPv6 is for the benefit of those who may not have been exposed to it before. As you probably know, the Internet is based on the IP protocol. The current implementation of the IP […]
Read moreAn introduction to the IPv6 address space. The IPv6 Address Space The most obvious difference between the two protocols is the length of their source and destination addresses. The whole point of making the switch to IPv6 is to compensate for a global shortage of IP addresses. It only makes sense that the IPv6 protocol has a larger address space than […]
Read moreThis article will continue the introduction to the IPv6 protocol by discussing IPv6 address formatting and the various types of IPv6 addresses. In the first part of this article series, I talked about some of the differences in the way that IP addresses are expressed in IPv6 as opposed to the way that addresses are expressed in IPv4. In this […]
Read moreIn Part 2 of this article series, I explained that there are actually three different types of IPv6 addresses; unicast, multicast, and anycast. In that article, I briefly explained that unicast addresses are used to identify an individual host on a network. Multicast addresses, on the other hand, identify a group of network interfaces that typically reside on multiple computers. When […]
