Linux Viruses – A Threat?
Viruses in Linux are uncommon, but on the rise.
Linux is growing in popularity. It is being used in more devices constantly; Routers, servers, gadgets etc. This is likely to cause more virus developers to focus their attention on Linux. But Linux is much more resilient than its counterparts. But why?
Safely Installing Linux for Beginners
There’s no denying that Linux will play a big part in future of computing. With most of the world’s super computers and servers running Linux it’s essential to any computer-guru teenager to get an early grasp on the concept of Linux. Do you want to try Linux? Then read on…

Data Link Layer – OSI Model Layer 2
Tip:- This post is part of the series the Complete Guide to the OSI Model.
In getting from A to B, a packet may be routed through several networks. The Data Link Layer is responsible for establishing each link.
The data link layer is the second layer from the bottom in the OSI Model. The OSI Model details computer networking from start to finish. The Data Link Layer receives a packet from the Network Layer and sends a frame to the Physical Layer for signalling. The data link layer does several things. It holds a link between two points, this is what makes it important; it will enable us to maintain a point-to-point link between two devices. This “point-to-point” link may not be the packet sender to the packet recipient, multiple point-to-point links may (and quite often do) need to be established.
Physical Layer – OSI Model Layer 1
Tip:- This post is part of the series the Complete Guide to the OSI Model.
Cat5e cables are often used for Ethernet connections.
The physical layer is the bottom layer of the OSI Model. The OSI Model details computer networking from start to finish. The physical layer, as the name may suggest, is the layer where we physically send our finalised frame over any medium. When I refer to “medium” this could mean anything.
The OSI Model: Lego House Example
Tip:- This post is part of the Complete Guide to the OSI Model series.
James May wants to send his lego house to a friend.
The OSI Model is a model set out by International Organization for Standardization (ISO). It is one of many models that separates computer networking into understandable sections we can follow not only to understand networking, but also to ensure that any hardware we make conforms to the required standards.
I struggled for a while to get to grips with the OSI Model and what it actually was. This prevented me from properly understanding Computer Networking until I bit the bullet and went for a Networking Degree at University. While completing the course (and after several quarrels with my lecturer) it quickly became apparent to me how easy the OSI Model is to grasp if you have a basic understanding of software and hardware. It’s often over complicated, and it doesn’t need to be, it’s a simple idea.
While learning about the OSI Model I found it much easier to compare it to my own analogy of the postal system (sending a letter or package). You can break anything up into layers and this is the best example I can think of. Hopefully it will help you understand the OSI Model. Read more

The Complete Guide to the OSI Model
This complete guide isn’t yet finished or published. This is a preview.
The OSI Model defines the way computers communicate, and ultimately how you stay in touch with friends.
Computer Networking is a very complex area to study. In courses, people often find themselves struggling more over networking than they do architecture. Ironically this is because it is easier, and is explored more in depth in intermediate to advanced courses. Commonly “The OSI Model” will be used to illustrate the structure of computer networking. This series of articles explores what the OSI Model actually is, and why it is necessary. It will also provide an example for each layer using a non-computing based approach.
Switchover: How Files are Handled
As far as Linux goes, one of the most confusing and frustrating things for those who predominantly use Windows, the way that Linux structures files. Every operating system will have its own way of dealing with files. This guide aims to compare Windows file structure with the Linux file structure and explain how files are handled in Linux.
