Most of you are using IE now I will introduce to another exciting browser Mozilla.

It has the cool features which IE doesn't. instead of opening new pages in separate windows you can have them open in tabbed pages of the same browser window. If you have multiple pages you want the browser to open when you launch it, just make a group of tabs your startup group.

Whereas IE has a global setting for remembering web page passwords, Mozilla lets you specify web pages for which you want it to remember passwords and you can use the password manager to remove remembered passwords at any time. Add in a built-in download manager, integrated e-mail client, multiple profiles, a built-in chat program, integration with popular search engines, and the distance between Mozilla and IE starts to look impressive.

However, Mozilla really shines when it comes to annoying web sites. It includes a built-in popup manager where you can configure popup filtering on a site-by-site basis if you desire. It has a cookie manager you use to block cookies, also by site if you want, and to view the cookies that have been dropped on your system. You can also configure Mozilla's behavior when it comes to images. Most sites that have obnoxious banners pull the graphic files from external sponsor sites and you can configure Mozilla to ignore external images, again, site-by-site if you want. Finally, a nice visual touch is Mozilla's skinning support, with numerous skins freely available

KNOPPIX is a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. KNOPPIX can be used as a Linux demo, educational CD, rescue system, or adapted and used as a platform for commercial software product demos. It is not necessary to install anything on a hard disk. Due to on-the-fly decompression, the CD can have up to 2 GB of executable software installed on it.

What software is installed on the KNOPPIX-CD?

1. Linux-Kernel 2.4.x
2. KDE V3.0 as the standard desktop with K Office and the Konqueror WWW-browser konqueror
3. X Multimedia System (xmms) an MPEG-video, MP3, Ogg Vorbis Audio player and xine
4. Internet connection software kppp,pppoeconf (DSL) and isdn-config
5. Gnu Image Manipulation Program (GIMP) Version 1.2
6. utilities for data recovery and system repairs, even for other operating systems
7. network and security analysis tools for network administrators
8. OpenOffice(TM), the GPL-developed version of the well-known StarOffice(TM) office suite
9. many programming languages, development tools (including kdevelop) and libraries for developers
10. in total more than 900 installed software packages with over 2000 executable user programs, utilities, and games

What are the minimum system requirements?

1. Intel-compatible
CPU (i486 or later),
2. 20 MB of RAM for text mode, at least 96 MB for graphics mode with KDE (at least 128 MB of RAM is recommended to use the various office products),
3. bootable CD-ROM drive, or a boot floppy and standard CD-ROM (IDE/ATAPI or SCSI),
4. standard SVGA-compatible graphics card,
5. serial or PS/2 standard mouse or IMPS/2-compatible USB-mouse.

What is Bochs?

Bochs is a program that simulates a complete Intel x86 computer. It can be configured to act like a 286, 386, 486, Pentium, or Pentium Pro. Bochs interprets every instruction from power-up to reboot, and has device models for all of the standard PC peripherals: keyboard, mouse, VGA card/monitor, disks, timer chips, network card, etc. Because Bochs simulates the whole PC environment, the software running in the simulation "believes" it is running on a real machine. This approach allows Bochs to run a wide variety of software with no modification, include most popular x86 operating systems: Windows 95/98/NT, all Linux flavors, all BSD flavors, and more.

who should use?

Bochs has many possible uses, and different people use it for different things. Many people use it to run applications in a second operating system without needing two different computers or dual-booting. Running Windows software on a non-x86 workstation or on an x86 UNIX box are common uses. Also, because every hardware instruction and every line of simulator code is accessible, Bochs is used extensively for debugging new operating systems. If you were writing boot code for your home-brewed x86 operating system and it didn't work right, booting it in Bochs could give you great visibility into what is really going on. The Bochs debugger lets you simulate quickly or slowly, pausing whenever you want to look at the contents of memory or the CPU registers. Or, if you wanted to study which parts of a program take the most time, you could use Bochs to measure how often certain pieces of the code were executed.

Bochs has been used as a teaching tool in Operating Systems classes, in which students used and modified it to learn how the PC hardware works. As a final project the students had to add a new peripheral device, so they had to learn all about I/O ports, interrupts, and device drivers. In industry, it is used to support legacy applications on modern hardware, and as a reference model when testing new x86-compatible hardware.

There may be as many uses of Bochs as there are users. Do you want to run your old DOS games? Or learn how to program under Linux, without leaving your Windows desktop? Or reverse engineer your printer driver? You decide.
