Operating Systems Concepts

 Hello friends! This week's blog post is going to be a long one! I’ll be including a quick overview of many of the different concepts regarding the components of an operating system! Operating Systems   Operating Systems Major Functions Operating systems essentially act as the manager and translator for the entire computer. Operating systems are essentially here to ensure that when someone wants to do something on their computer, they aren't forced to sit down and treat the function as if they were doing math on an abacus. This management is essential to getting the end product you see when sitting down to a personal computer. That said, we can get into more specifics.   1.

Traveling Through a Network!

I sat down with my nine-year-old and had him pick any site he could think of, and we had fun watching the traceroute do its thing. This knowledge helped both of us learn and grow. This experience has been excellent and is a great way to illustrate the difference between ping and traceroute and what they can accomplish.

  Hey there! Loons here! Today's post is a longer one, so we're going to dive right in. We'll be talking about network security and the different ways nefarious entities try to keep the upper hand. In today’s world, with our reliance on computers at an all-time high, it is no wonder that criminals and nefarious entities have turned to attacks on computer systems to get what they seek. This can come in the form of direct attacks on individuals to steal sensitive information or larger-scale attacks on businesses or networks meant to do as much financial damage as possible. Sometimes, this is for financial gain or perhaps to convince a company or individual to do or not do something. This paper will give some details on a few types of attacks, what symptoms will help you know you are being attacked, and what options we have to attempt to prevent these types of attacks. The first example we will review here is the DoS attacks or denial of service attacks. These attacks can be e...
