What is the Cloud?

The CouldI have been asked if an internet connection is required, to be able to access “the cloud”.

I admit it gave me the giggles, which I (somewhat?) managed to suppress, enough to explain that — short answer — the cloud is the internet.

You didn’t think we were going to be talking about the big fluffy things, did you?

Linux Network Commands Part 3 – Management

Computer Data NetworkIt could be argued that configuration and management run hand in hand, and should not be separated.

I do not disagree. It is not an easy matter to draw a line between the two, especially in the case of network commands that can be used to test whether or not the configurations were successful.

All About Networks Part 1 – The Basics

Networks 101We all know what networks are. They’re arrangements of intersecting horizontal and vertical lines, or even groups of interconnected people or things. Right?

I hate to break it to you (not really) but there’s another definition, too.

Computer networks, or data networks, are a means by which multiple computers (or other devices such as printers, phones, tablets, etc.) are connected, so that they can exchange data, etc.
