Microsoft Windows
 
Microsoft created the operating system,
Windows, in the mid-1980s.
 
They have a version of the operating 
system

that is designed for the home user, and a
professional version, which is intended for
businesses.
 
The versions differ in the depth of 

networking,security, and multimedia support
Windows is a proprietary software, which means that Microsoft has placed restrictions on how people can use or copy the software. Windows comes preloaded on most of the PCs sold today, and can also be purchased separately Various versions of the software are priced from $79 to $399 for home users.

Microsoft has a big share of the operating system market. According to web analyst Net Solutions, over 90% of computer users have one of the Windows operating systems, such as Windows 98, Windows 2000, Windows XP, Windows Vista, Windows 7 or the most recent Windows 8, as of August 2013.
Apple’s Mac OS
Mac OS is a line of operating systems created by Apple Inc. The Mac operating system is proprietary software that comes preloaded on all new Macintosh computers, or Macs. 
The most recent version of the operating system is called Mac OS X (pronounced Mac O-S Ten). Like Microsoft, Apple offers a professional version of the operating system that is intended for use on servers and a version of the operating system that is developed for home users. 
 Mac OS X Desktop
According to web analyst Net Solutions, Mac OS users account for almost 7.5% percent of the operating systems market as of March 2008. Although the percentage of users is low, especially in comparison to Windows users, Mac operating systems have seen a dramatic jump in growth in 2007. Mac computers are sleek and modern looking, which has started to appeal to many home users.
The common version names of Mac OS X are Leopard and Tiger. There is Lion.
To learn more about the Macintosh computers Watch the Kawa Video about understyanding OS or visit the Apple Inc. website, and explore the Mac computers available, as well as the Support center for information about the Mac OS.
Linux
Linux is an open source, or free, operating system. Unlike Windows and Mac OS, Linux is not proprietary software and all the computer code that is part of the operating system can be used and modified by any user. 
 Linux was started in the 1990s when Linus Torvalds, a person interested in creating a free operating system, developed the Linux (pronounce lynn-ux) kernal, which is computer code that is a central part of an operating system. 
 As an open source software, any individual or company can take the Linux kernal and modify and add to it.
Hundreds of companies and individuals have taken the Linux kernal and added additional computer programs to create various versions of the Linux operating system. These versions are known as distributions and are available to download for free. 
 
Ubuntu Desktop: A Version of Linux
Linux is extremely popular in businesses, especially for servers, because it is adaptable. According to Net Application statistics, Linux represents under 1% of the market share for home users, but it does offer an alternative to commercial operating systems.
Despite being used in many businesses for servers, you do not have need to have special programming skills to download and use Linux. In fact, if you want to try Linux, you don't have to actually install it on your computer. Several versions of the operating system can be downloaded and burned to a CD.
Two popular distributions of the software are Ubuntu and Red Hat. Ubuntu is completely free and is available in a version geared specifically for home users.
 
Red Hat is a company that offers technical and training support for businesses that use its version of the operating system, Red Hat Linux.

Pen Input

Image
With pen input , users write, draw, and tap on a flat surface to enter input. The surface may be a monitor, a screen, a special type of paper, or a graphics tablet.  A light pen is handheld input device that can detect the presence of light. To select objects on the screen, a user presses the light pen against the surface of the screen or points the light at the screen and then presses a button on the pen.  A stylus is a small metal or plastic device that looks like a tiny ink pen but uses pressure instead of ink.   Some mobile computers and nearly all mobile devices have touch screens that recognize pen input. Most of these devices include a pressuresensitive digital pen or stylus. Pressure-sensitive digital pens typically provide more functionality than a stylus, featuring electronic erasers and programmable buttons. Computers and mobile devices often use handwriting recognition software that translates the handwritten lett...

Laptop, Tablets and Palmtop Computers

Image
The second type of computer that you may be familiar with is a laptop computer. Laptops are battery or AC-powered personal computers that can be easily carried and used in a variety of locations be a car, a taxi or airjet.    Example Laptop Computer The primary benefit of a laptop computer is its small size and easy portability . They use special screens, rather than the traditional bulky VDUs (Visual Display Units), which allows for longer battery life as well as portability. A laptop computer is sometimes called a notebook computer because of its size. Notebooks and Palmtop computers A newer term, “Notebooks”, simply indicates a VERY small laptop. These are especially popular with salespersons on the move or people giving presentations. While they tend to still be more expensive than an equivalent Desktop computer, they can now match the power of a Desktop computer. Palmtops are even smaller computers which can literally...

Measuring Memory

Image
Information is stored in the form of bytes.   A byte is a unit of memory in a computer and this byte represents either a character e.g. B or two digits e.g. 12.   These bytes are formed from bits.   Bits, or Binary Digits, may have one of two values.   These are represented by 0 or 1, true or false, but will actually be the presence or absence of magnetisation. Relationship between Bits, Bytes, Kilobytes, Megabytes and Gigabytes A Bit is the smallest element of data storage.   Bits grouped together form bytes.   With the ASCII code a combination of 8 bits form 1 byte.   For example when you type a letter ‘a’ the computer will understand that as a combination of zeros and ones e.g. 01100001.   The following indicates the relationship between different data units 8 bits = 1 byte 1024 (2 10 ) bytes = 1 Kilobyte 1 048 576 (2 20 ) bytes = 1024 Kilobytes = 1 Megabyte 1 073 741 824 bytes = 1024 Megabytes = 1 G...
