Cloud computing is used a lot these days. Many times people are referring to totally different concepts. When mentioning it, however, there is definitely a disconnect or a lack of understanding of what this means. I will clear some things up and give a good overview of what we are talking about when we say “cloud computing”.
A computer network can handle a lot of different roles these days. Essentially it pushes data around to devices and controls what happens. Some of the more interesting uses for a network now is VOIP communications and video conferencing. In this guide to network communications I go over some of those details.
I have talked about computer networking devices before in previous articles. Today, however, I will go into more detail and cover some of the more common devices in more depth. The most common devices are access points, routers, firewalls, and switches. In their respective sections I want to discuss some of the details that I had to leave out before.
Network Basics: Easy Addressing and Routing is all about the TCP/IP protocols and what they do. Our present day internet is totally dependent on this system because because of how it developed and without a doubt it can be confusing.
Think about it:
The reason TCP/IP was used was because it was rock solid. However, it seems like there are a million details to it and I am sure you would agree with me. The addressing and routing that moves all of our internet traffic between Facebook, Twitter, and all of our other favorite websites uses TCP/IP primarily so there has to be a reason for it right? There really is so let me explain to it to you.
The OSI model is a theoretical framework on how networking works. It tries to tie together all of the different protocols that we depend on today to use the internet. In this guide I explain what it is in as much detail as I can and how it is used because knowing how the OSI model works can be very useful. [Read more…]
I wrote this article to help people understand basic network devices. It would be useful to individuals who want to learn a few more details and for anyone studying to take a networking exam such as Network+. I try to focus on the application of these network devices and what they are used for.
Networking hardware is pretty diverse. It has always been this way. The various pieces you can buy can have a lot of functionality or it can specialize in one or two functions. Networking hardware has dramatically improved over the years as well. For example, the original repeaters and hubs were quite dumb devices. We have almost the exact level of technology in some of our USB hubs today. Today though we have devices in environments that can do amazing things. Some of these can do almost everything, and well, in just one box. Please read on for more information and don’t forget to subscribe and share this article please.
Networking is a popular topic. Microsoft has extensive needs in their systems. Cisco certifications are always highly sought after. It only helps your career if you have knowledge of networking basics. It is how we play our lan games and how our phones communicate also. Being a very popular subject because of Cisco jobs and equipment especially, I wanted to start a series to address it. At the most fundamental level you have the different topologies. Networking topology, at its core, describes in a high level view how a network is set up. There are many different kinds of topologies such as Ethernet, bus, ring, star and some other obscure ones. In actuality though, Ethernet is the only one worth talking about these days as most of the others have fallen out of use. [Read more…]
