Installing Linux defining distros which version should you choose

Which version of Linux should you choose?In April 1991, Linus Torvalds, at the time a 21 year old computer science student at the University of Helsinki, Finland, started working on some simple ideas for an operating system. Although the desktop computer market exploded throughout the 1990s, the Linux Operating System remained pretty much the domain of geeks who like to build their own computers. I really believed that more than 20 years later we would have Linux computers in our home as common as Windows or Apple varieties.

The only dent in the domination of Windows or Apple desktop computers in recent years has been the introduction of the Chromebook as a personal computer in 2011. The Chrome operating system is a strange mix of the Linux kernel and using the Google Chrome web browser as a user interface.

The Linux operating system has come a long way since the mid 1990s. From painful experiences with using floppy disks and hunting down hardware drivers, my experiences with installing many distributions of Linux in recent years has been pretty painless.

Desktop personal computer system basic parts defined

Learning basic computer conceptsIf you are studying personal computers as the beginning of your career in technology, or perhaps you are just trying to understand how things work on your home computer to better deal with problems and upgrades, you can't get away with not knowing some very basic definitions of the components of a desktop personal computer system.

There have been so many types of hardware and software over the years, keeping up to date on what is current is a full time job for many computer support technicians. This section is meant to be a brief introduction to common personal computer terms, we are only introducing you briefly to the basics.

If you are interested to learn more, many of the topics described here are covered in more detail throughout the websites of the Guru42 Universe. Over at our sister site we explore the history of technology and the evolution of personal computers.

The Data Link Layer of the OSI model

A network interface controller (NIC)The Data Link Layer is Layer 2 of the seven-layer OSI model of computer networking.  The Data Link layer deals with issues on a single segment of the network.

Layer two of the OSI model is one area where the difference between the theoretical OSI reference model and the implementation of TCP/IP with the competing Department of Defense (DoD) model. As we will discuss with the implementation of TCP/IP there is one lower layer called the network interface layer that encompasses Ethernet.
