Multitasking: Linux has the ability to handle more than one job at a time, say for example you have executed a command fir sorting for a huge list and simultaneously typing in a notepad. This is manage by dividing the CPU time intelligently by implementation of scheduling policies and the concept of context switching.
Portability: portability was one of the main features that made Linus so popular among the users, but portability doesn’t mean that it is smaller in file size and can be carried on pen drive , CD’s and memory cards.
Instead, here portability means that Linux OS and its application can work on different types of hardware in the same way. Linux kernel and application programs support their installation even on every least hardware configuration.
• Security:security is a very important part of any OS, for the organization/user who is using the system for their confidential works, Linux does provide several concept for protecting their users from unauthorized access of their date and system.
• Linux is fast, free and easy to use, power laptops and servers around the world. Linux has many more feature to amaze its
users such as:
• Live CD/USB: Almost all Linux distribution have Live CD/USB feature by which user can run/try the OS even without installing it on the system.
• Graphical user interface (X Window System): People think that Linux is a command line OS, somewhere its true also but not
necessarily, Linux OS have packages which can be installed to make the whole OS graphics based as windows.
• Support’s most national or customized keyboards: Linux is used
worldwide and hence available in multiple languages, and supports most of their custom national keyboards.
• Application support: Linux has its own software repository from
where users can download and install thousands of applications just by issuing a command in Linux Terminal or shell. Linux can also run Windows application if needed.
1.2 CLONING
In computing, a clone is a hardware or software system that is designed to function in the same way as another system. A specific subset of are Remark (or Remades), which are revivals of old, obsolete, or discontinued products.
When IBM announced the IBM PC in 1981, other companies such as Compaq decide to offer clones of the PC as a legal reimplementation from the PC’s documentation or reverse engineering. Because most of the components, except the PC’s BIOS, were publicly available, all Compaq had to do was reverse-engineer the BIOS. The result was a machine with better value than the archetype that the machines resembled. The use of the term “PC clone†to describe IBM PC compatible computer fell out of the in the 1990s; the class of machine it now describes it now are simply called PCs. While the term has fallen mostly into commercial disuse, the term clone for PCs still applies to a PC made to entry-level or above standard ( at the time it was made ) which bears no commercial branding (e.g Acer, IBM, HP, Dell). This includes, but is not limited to PC assembled by home user or Corporate IT Departments.
The components to be cloned are:
SYSTEM CASE
A computer case also known as a computer chassis, tower, system unit cabinet, base unit or simply case and sometimes incorrectly referred to as the “CPU†or “hard drive†is the enclosure that contains most of the components of a computer (usually excluding the display, keyboard and mouse).
Cases are usually constructed from steel (often SECC –Steel, electro- galvanized, cold-rolled, coil) or aluminum. Plastic is sometime used, and other material such as glass, wood and even Lego blocks have appeared in home –build cases.
