What are libraries and why use libraries in c ? A library is a file containing several object files, that can be used as a single entity in a linking phase of a program. Normally the library is indexed, so it is easy to find symbols (functions, variables and so on) in them. For this reason, linking a program whose…

ls is one of the most common commands in a Linux shell and probably the first command that you would use when learning Linux. Let’s take a look at what ls does when we enter it in a shell: As you can see it prints all available files and folders…

Computer machines are composed by digital memories that store information in bits (binary digit). It means that a bit is an unit — the smallest one — used to quantify computer data . The bit represents a logical value, which corresponds to a two-state device. …
