Linux OS Performance - Assignment Example

The benefits of open source have been endless for organizations who attempt to save up server costs. Organizations such as IBM have been utilizing Linux for decades now. Around 30% of PCs run LINUX, and 60% of servers run Linux (http://www.linux.com/).

Before understanding Linux, it is crucial to look at how it was developed. In 1991, a gentleman known as Torvalds became curious about OS and invented this system at the University of Helsinki. He began to work on his operating system which eventually became the kernel. Additionally, developers worked to integrate GNU components with the Linux kernel, making it a fully functional and free operating system. At that time, the notion of an open-source system was not fully developed. It was Torvald’s value of OS that lead to the development of this. Linux can be downloaded from www.linux.org. Linux, which began only from the server side, has also manifested itself as a desktop OS, and can also be used on all of these devices. One of the most unique elements of Linux is the fact that it has many Linux distributions, or "distros". These distros allow end users to manage a remote collection of system software and application software. Just as java has plug-ins and jars, these distros can be downloaded and act together as a component which is crucial to developers. Moreover, this allows users to adapt the operating system to their specific needs. These distros are maintained by volunteers and developers who continue to strive to make progress (http://www.linux.com/).

Linux can be used in supercomputers, which is a huge benefit. Linux is fairly easy to use even though it is not object-oriented programming. The user interface, also known as shell or GUI in modern days is utilized by the user to execute commands. Using the shell or GUI through controls attached to the associated hardware, which is common for embedded systems. For desktop systems, the default mode is usually a graphical user interface, although the CLI is available through terminal emulator windows or on a separate virtual console (http://www.linux.com/).

SSH is a secure way of accessing a remote server whereas telnet just establishes a connection without encryption. You can conduct a file connection session to connect to LINUX.

Basic commands are: Directories: List, view, copy, move, delete (hint: show me five commands); Copy:cp directory; Move:mv; List:dirs; View:diff; Delete: dl; Files: List, view, copy, move, delete; List: cp source dest; View: cp source directory; List: cp source dir; View: vi or view; Text Files: Edit and move (page up page down, etc.) using Pico; Pico up: <^p>; Pico down <^n> (http://lifehacker.com/learn-basic-linux-commands-with-this-downloadable-cheat-1552019180).

When it comes to partitioning your machine, there is no universally correct way to do it. Many factors must be taken into account depending on the purpose of the machine. For a laptop, a user can execute partitions. A partition for /, /boot, and swap. However, for most users, this is not a recommended solution. Disk space goes from 4G to 8G/

Process status command shows the list of information of each process (http://www.computerhope.com/issues/ch000773.htm)

Grep is more of an elaborative process of searching. The Grep for the file is an example:
How do you transfer files to a Linux box? Hint: ftp/ssh. - FTP:ssh tar -c dir/ | gzip | gpg -c | ssh user@remote 'dd of=dir.tar.gz.gpg (http://www.computerhope.com/issues/ch000773.htm).

Super use has all the privileges and can enable based on choice. The Sudo command stands for "superuser do". It prompts the user for a personal password and confirms your request to execute a command by checking a file called sudoers.
