Notebook, or laptop, is a portable computer that normally have : Screen size : 12 Inch and up Processor : Intel Pentium Dual-Core,Core 2 Duo or AMD Turion X2 Graphics : Integrated or External Graphic Card, from Intel GMA x3100 to AMD Mobility HD 3870X2 Weight : 1.9kg and up
NETBOOK
Netbook,a smaller variant of notebook, 1st poineered by Asus with their release of Asus Eee PC 700,and now laptop companies such as Acer and MSI released their own netbooks (Acer aspire one and MSI wind respectively), have : Screen size : 12 Inch max Processor : VIA C7 1.2GHz, Intel Atom N270 1.6GHz or AMD Geode 800MHz Graphics : Integrated Graphic Card, mostly Intel GMA 900 or 950 Weight : 1.1kg and below
COMPARISON
1st, let's compare the screen size. With notebook screen size normally hovers around 14.1 to 15.4 inch, you can have a good movie viewing pleasure and don't have to squint your eyes just to see some text. With screen size 12 inch and lower, you might have a hard time typing documents in your netbook. 2nd, the processor. It is a very important part or consideration because it process the website content. The faster the processor, the faster the page loads. If you normally surf around the YouTube (which is heavy in javascript and flash) then you will know that loading that website takes longer than sites such as wikipedia or forums. With a slow processor, you browser might suddenly hangs if you opened too much tabs. The netbook cpu can't even handle 1080p movie and it will shutter all the way till the end. 3rd, the graphic card. If your primary concern is playing games, you can skip the netbook altogether as their graphic are really really lame. Some claim that they install World of Warcraft inside their netbook, but with lame graphic card and small screen, how are you ever gonna enjoy playing that game. On the other hand, notebook have better graphic card than netbook even in the low-end section. They can handle World of Warcraft and other older games easily without breaking a sweat literally. 4th, the weight. This is where the netbook really shines. With their low weight (and small screen), they are truly fit the definition of portability. Thier weight are almost half of the notebook weight, which is a good thing if you're not into bodybuilding. Coupled with their power adapter, the max weight might be only 1.5kg. In the end, it all boils down to you. Which one you prefer the most. If you like to play games or watch movies, notebook is the way to go. If you surf the web more often and type short documents, netbook is you choice. Be warned that netbook keyboard is really small and not suitable for long-term typing.

OPEN OFFICE is a free suite of applications suitable for a variety of operating systems such as Linux, Microsoft Windows, Solaris, OpenVMS, IRIX & Mac OS X(1). Open Office supports the open document standard for data interchange.
Open office suite is an open source code application, which has been developed by Tetra Information Services as per their client needs. Open office source code was released in July 2000 with an aim to reduce the dominant market share of Microsoft and is available under GNU Lesser General Public License (LGPL).
It is basically a programming language similar to Microsoft Visual Basic for Applications (VBA). It is available in the Writer and Calc applications. It is written in functions called subroutines or macros, with each macro performing a different task, such as counting the words in a paragraph and is especially useful in doing repetitive tasks that have not been integrated in the program
Open Office packages are similar in look and feel, very easy to use and offer some amazing benefits. Common tools are used across the suite, you therefore do not have to remember, which application or tool was used to create a particular file. A ‘File Open’ command on Open Office from anywhere and can launch the correct application. Most of the documents are saved in OpenDocument format, which is the new international standard data from the OpenDocument compliant software.
Open Office is a collection of applications that work together closely to provide features expected from a modern office suite. Many of the components are designed to mirror those available in Microsoft Office. The components available include:
WORD Word processor similar in look and feel to Microsoft Word and offers a comparable range of functions and tools. It also includes the ability to export Portable Document Format (PDF) files with no additional software, and can also function as a WYSIWYG editor for creating and editing web pages. One important difference between Writer and Microsoft Word is that in Writer, many functions and number formats from Calc (below) are available in Writer's tables.
CALC Spreadsheet is similar to Microsoft Excel with a roughly equivalent range of features. Calc provides a number of features not present in Excel, including a system which automatically defines series for graphing, based on the layout of the user's data. Calc is also capable of writing spreadsheets directly as a PDF file.
IMPRESS It is similar to Microsoft PowerPoint. It can export presentations to Adobe Flash (SWF) files & allow them to be played on any computer with installed Flash player. It also includes the ability to create PDF files. Impress suffers from a lack of ready-made presentation designs. However, templates are readily available on the Internet.
BASE It is a Database program similar to Microsoft Access. Base allows creation and manipulation of databases and building of forms and reports to provide easy data access to end users. As with Access, Base is able to work as a front-end to a number of different database systems, including Access databases (JET), ODBC data sources and MySQL/PostgreSQL. Base became part of the suite starting with version 2.0.
DRAW Draw is a vector graphics editor comparable in features to CorelDraw. It features versatile "connectors" between shapes, which are available in a range of line styles and facilitate building drawings such as flowcharts. It has similar features to Desktop publishing software such as Scribus and Microsoft Publisher.
MATH Is a tool for creating and editing mathematical formulae, similar to Microsoft Equation Editor... Formulae can be embedded inside other Open Office documents, such as those created by Writer. It supports multiple fonts and can export to PDF.
QUICK STARTER Though a small program for Windows and Linux that & runs when the computer starts for the first time. It loads the core files and libraries for Open Office during computer startup and allows the suite applications to start more quickly when selected later. The amount of time it takes to open “Open Office” applications was a common complaint in version 1.0 of the suite however Quickstarter was a solution of sorts. Substantial improvements were made in this area for version 2.2.
MACRO RECORDER Macro Recorder is used to record user actions and replay them later to help with automating tasks, using OOoBasic.
DRAW
What is Draw? Draw is a vector graphics drawing tool, although it can perform some operations on raster graphics (pixels). It offers a series of powerful tools that enable you to quickly create a wide variety of graphicalimages. Vector graphics store and display a picture as simple geometric elements (lines, circles, polygons, etc) rather than as a collection of pixels (points on the screen). This permits simpler storage and supports precise scaling of the picture elements.
Draw is fully integrated into the OpenOffice.org suite, and this makes exchanging graphics with all components of the suite very easy. For example, if you create an image in Draw, reusing it in a Writer document is as simple as copy and paste. You can also work with drawings directly from within Writer or Impress, using a subset of the functions and tools from Draw. Draw’s functionality is extensive and even though it was not designed to rival high-end graphics applications, it possesses significantly more functionality than the drawing tools that are generally integrated with office productivity suites.
A few examples of the drawing functions are: layer management, magnetic grid-point system, dimensions and measurement display, connectors for making organization charts, 3D functions enabling small three-dimensional drawings to be created (with texture and lighting effects), drawing and page style integration, and Bézier curves.
