The Journey From High Level to Low Level Technology

In today's electronics filled world you'll find that of most of these devices have a simple chip. Everything from a computer to a smart phone to a GPS all have the same building blocks that come together in uniformity to create what we come to know as modern electronic devices. Of course there are detailed equations and formulas that describe everything about the voltages, electric and magnetic fields and even power dissipation. This is something far beyond the scope of this article, however what I do want to discuss is the different levels of technology from its highest to its lowest levels that make today's technologies all possible.

Pipes in Unix Based Operating Systems

Unix based operating systems like Linux offer a unique approach to join two discrete commands, and generate a new command using the concept of pipe(lines). For example, consider command1|command2. Here, whatever output is generated by the first command becomes the standard input for the second command. We can develop more and more complex Unix command sequences by joining many commands while maintaining input output relationships.
Another more Linux specific example would be ls -l|grep "^d". This command displays details of only directories of the current working directory, i.e. the output of the 'ls -l' command becomes the input to the grep command, which displays only those lines that start with 'd' (they are nothing but the details of the files).
ls -l | grep "^d" | wc -l

What Is the Current Demand for Computer Forensics Certification?

In recent years, there have been a record number of computer security related crimes than ever before. The more that digital technology advances, the more chances that computer criminals will take advantage and find new ways of stealing and destroying data. That is why the growing interest in computer forensics training is becoming a sought after field for those wanting a high paid and stable forensics career.
If you want to pursue a computer forensics education, there are many forensics classes you will need to complete to get your forensics degree. The basis of your forensics classes will be to become a forensics specialist who can solve computer crimes successfully.

Open Source Development - Secure or Not?

It is a common notion that open source as opposed to the proprietary software is more prone to breaking down due to the ability of code crackers to manipulate the source code to malfunction. While this point of view is justified, because you can actually see the code, modify it and re-distribute it, it would be very presumptuous to say that it is unstable and unsecure. With the advent of internet businesses that operate completely online, security became an inevitable need and an unavoidable concern. This also does not mean that proprietary software are uncrackable (given the fact that there is no access to source code and there is a huge price via licensing) the most standardized software can be invaded due to their predictability as well. And the debate never ends!
