LINUX
PRECEDENTS Initially  it was developed by Linus Travalds in the University of Helsinki in Finland. One was inspiring in Minix, a small UNIX developed by Andy Tanenbaum
CHARACTERISTICS Multitask Multiuser Free acces to develop or to modify Modules. Virtual multiple offices that they make several meetings Almost all the implementations are of virtual memory.
GENERAL STRUCTURE Can be divided into several distinct components. Kernel:  It’s the heart of the system, it possesses a great number of functions of system that they are invisible for user. Shell:  It acts as interpreter of commands. It’s a program that reads them given orders, it decodes them and reports to the kernel to realice the action specified.
ACCESS PERMISSIONS Linux system keeps a very strict access permissions, to control what can be done and who can do. These permissions are identified with letters and are: R  Permission of reading in the file W  Permission of writing in the file X  Permission of execution of the file S  Permission to change the owner of file
INSTALLATION RECOMMENDATIONS Installation is not a simple process. should consider several key aspects: Disk partitioning Bootloader Drivers monitor and video card Not accept the functions defaults unless security is the right choice
