many different versions of Windows, but the most
recent ones are Windows 10 (released in 2015),
Windows 8 (2012), Windows 7 (2009), and Windows
Vista (2007). Windows comes pre-loaded on most

Linux (pronounced LINN-ux)is a family of open-
source operating systems, which means they can
be modified and distributed by anyone around
the world. This is different from proprietary software
like Windows, which can only be modified by the
company that owns it. The advantages of Linux
are that it is free, and there are many different
distributions—or versions—you can choose from.

1.When the user powers up the computer the CPU (Central Processing Unit) activates the
BIOS (Basic Input Output System).
2. The first program activated is POST (Power On Self-Test). Using the CMOS
(Complementary Metal Oxide Semiconductor) memory this checks all the hardware and
confirms that all are functioning properly.
3. After that it reads the MBR (Master Boot Record) in boot drive in accordance with the
firmware ‘bootstrap loader’ which is Provided by the computer manufacturer.
4. Then the computer loads in the Operating System in boot drive to the RAM (Random
Access Memory). This whole process is called booting which means that an Operating
System is loaded into the RAM (main memory)
