How Computers Work: What is a pixel?
Have you ever peered really deeply into a TV or computer screen? If not, try it right now! All those little dots you saw are called pixels. The word "pixel" is actually a combination of two words. "Pix" refers to pictures and "el" refers to element. This makes sense if you think about each individual pixel as a tiny piece making up a larger image. Generally, pixels are made up of four different colors - red, blue, yellow, and black - which are used in different combinations to form the different shades of colors you see.
Sorry if this post seems a little short, but I've had my mind on a bigger problem. It looks like someone has been using more than their fair share of the network. It's almost like they've been downloading non-stop for the past week or so! I think I'll go let Officer Ward know.

Cyber Defense Threats: Memory Leaks
Has someone ever queried you and, though you know the correct response, you just can't seem to access that memory file? I know I have! For you flesh-and-blood beings, it's probably nothing more than an off day. For us machines, however, it could be something much more serious known as a memory leak.
As you may know, all computer processes need a certain amount of memory in order to run. Memory leaks occur when a program never gives back the memory even after it's been closed. Over time, this memory loss can lead to a slower computer or even a computer that constantly crashes. From what I understand, it is similar to when humans have a lot on their mind and can't focus on anything else. Since most memory leaks are caused by viruses or bugs, the most efficient way to protect your machines is to run traditional anti-virus programs. As they say, better safe than. what was that last part? I'd better go check myself for leaks.
