A Web server is a program that, using the client/server model and the World Wide Web's Hypertext Transfer Protocol (HTTP), serves the files that form Web pages to Web users (whose computers
contain HTTP clients that forward their requests). Every computer on
the Internet that contains a Web site must have a Web server program.
Two leading Web servers are Apahe , the most widely-installed Web server, and Microsoft's Internet Information Server ( IIS ). Other Web servers include Novell's Web Server for users of its NetWare operating system and IBM's family of Lotus Domino servers, primarily for IBM's OS/390 and AS/400 customers.

The Ubuntu Installation Guide
I hope my guide makes installing Ubuntu an enjoyable, simple experience.
By the end of the guide you should have a dual boot Windows / Ubuntu
machine that happily plays music, video, and acts as a perfectly usable
home office computer with Openoffice 3.0. For the really adventurous you could even run Windows XP inside
Virtualbox, which is linked to later on in the guide. The Ubuntu OS is
unique and seriously cool, so, enjoy the trip.
1) Download the Ubuntu ISO from http://www.ubuntu.com/getubuntu/download and save to your desktop
2) Burn the ISO image to a blank CD using Roxio CD creator or similar:
3) Run the CD from “My Computer” – the CD should ask permission to run at which point you’ll see this option screen:
Install Ubuntu with Wubi
4) If you’d like to instal Ubuntu using Wubi ,
select “install inside Windows” and follow the instructions. Installing
with WUBI is ideal for a first taste of Ubuntu as you can remove from
add/remove programs in Windows later on. This install process is really
easy but you don’t get the same performance as if Ubuntu had a separate
partition running on its EXT3 file system. The following screens are all
based on the Wubi installer process, so you can follow the rest of the
instructions below.
If you’d like to install Ubuntu separately to Windows, then skip to point 7) below.
Here’s what you see next:
If you’ve got the space on your hard drive, go for 30gb or more for the installation size.
5) Now configure your installation using the simple settings options.
You can specify the location of the Ubuntu installation on your Windows
partition, the size of the Ubuntu installation, the Ubuntu flavour
(Ubuntu, Kubuntu, Xubuntu, etc), your preferred language, and a username
and password for the Ubuntu system.
When you click install, you’ll see this screen:
As soon as the files have finished downloading, you’ll see this:
6) That’s it! Click reboot now, and select “Ubuntu” on the startup screen. You now have a fully functional dual boot Windows / Ubuntu machine.
Install Ubuntu on a single (EXT3) partition (separately to Windows)
7) Click “Demo and full installation” and your computer will restart and boot into Ubuntu.
It’s worth saying at this point that you’re about to install Ubuntu
on an entirely separate drive partition. That means, you need to make
sure you have enough space on your computers hard drive to accomodate
the new setup. Keir Thomas found that a partition less than 4gb would
lead Ubuntu to crash during install in his first look at Ubuntu 9.04 over at Lifehacker.
Here’s a guide on how to resize or shrink your Windows Vista partition.
Follow those instructions before you reboot into the live version of
Ubuntu and you’ll have a really easy time during the following steps.
Maybe you’d like to install from a USB? Let’s have a quick look at the
process of installing from a USB before we continue:
8) Format your USB stick with a FAT32 partition from Windows. You can
get to the format dialogue by opening My Computer and right mouse
clicking the removable drive icon. Click “Format” and follow the
settings in the image below. You need a minimum 2gb USB stick.
9) Download UnetBooting .
UNetbootin allows for the installation of various Linux/Ubuntu
distributions to a partition or USB drive, so it’s no different from a
standard install, only it doesn’t need a CD. The coolest thing about the
application is that it’s a “portable” app. You don’t need to install it
into Windows meaning UNetbootin will run on your Windows PC without
“admin” privileges.
The new version of Ubuntu isn’t in the Distribution list supplied
with UNetbootin yet, so use the downloaded Ubuntu ISO from earlier on.
Add the ISO using the “Diskimage”, make sure your USB drive is selected
below and click OK.
The ISO transfers to the USB pretty quickly, so soon after you click OK you’ll see this screen:
10) That’s it – when the installation process is complete, restart
your computer and make sure it’s set up to boot from USB. On my HP
Laptop, pressing F9 on the boot screen shows a boot order menu.
Selecting “USB Hard Drive” follows a black screen, an Ubuntu logo, and
finally, your new Ubuntu desktop appears.
Completing your Ubuntu installation, step by step
Installing Ubuntu is so easy that it requires very little effort past
this point. If you’ve managed to repartition your hard drive and
restart your computer you’ll sail through the next few steps:
11) Click “install” on the live desktop (top left)
12) Choose your language in the welcome screen
13) Choose your location
14) Choose your keyboard layout
15) Set up your disk partition. This is probably the most “technical” part of the installation. When I shrunk my Windows Vista drive volume , I never formatted the new partition, which means the “use the largest continuous free space” option works nicely:
16) Choose your username and password:
17) Migrate your Windows documents and settings
18) You’re now ready to install your new Ubuntu installation
19) When the installation has finished, restart your computer (you’ll be instructed to remove your cd rom or USB drive). You’re now ready to begin using Ubuntu!
Useful tips and resources for Ubuntu (^_^)
Antivirus Software
All security software is not created equal. Like all consumer
products, antivirus software has the good, the bad and the mediocre.
The choices for antivirus protection are many and varied. We feature the
best antivirus software available today from a number of providers and
compare them. When it really comes down to it, effectiveness and
usability can either make or break antivirus software. Our top-ranked
antivirus software combine optimal security with user-friendly features
and tools.
Below are the criteria TopTenREVIEWS uses to evaluate and compare antivirus software:
Scope of Protection
While most security solutions tout multi-layered protection and 360-degree defense, some are more thorough than others. The best antivirus solutions will include traditional protection from viruses, worms, Trojans and spyware, but should also include defense from keyloggers, phishing scams, email-borne threats and rootkits. While antivirus programs are by no means full-blown internet security suites, they should protect from as many threats on as many fronts as they can.

While antivirus programs are by no means full-blown internet security suites, they should protect from as many threats on as many fronts as they can.
Effectiveness
Antivirus is specifically designed to protect your computer, so if it doesn’t do that well, what good is it? All the features, bells and whistles and sleek interfaces can’t make up for poor performance. We look at results from the industry-standard security software testers and professional security organizations to find the most effective software available.

Ease of Installation and Setup
Security software shouldn’t be a chore to install and should have you protected as soon as possible. From download to install, to the first scan, implementing antivirus software should be quick and easy.

Ease of Use
Antivirus software is complex stuff, but shouldn’t require a degree in computer security. The best security programs have all the features security experts want, but are just as easiy for a beginner. Everyday computer users want a security solution that they can install and forget about; software that doesn’t require constant maintenance or have annoying interruptions. The best antivirus software is flexible enough to do exactly what you want to (even if that means running by itself).

Security software is only as good as its latest update. Viruses are being identified and added to signature databases all the time. So it’s important that your virus definition list updates accordingly. Modern antivirus software are equipped with automatic updates that perform regularly enough that you get faster updates that don’t slow down your system. The best security providers push updates to you as soon as they’re available.

9 Best Free Antivirus Programs
Anti-Virus Free from AVG is the best free antivirus software
available. AVG Anti-Virus Free is a full-fledged antivirus and
antispyware tool, includes an email scanner, link scanner, scheduled
scanning options, automatic updates, and more. There is no need to pay
for an antivirus program when the best free antivirus software in the
world is just a download away.
AVG Anti-Virus Free works on Windows 7, Windows Vista, Windows XP and Windows 2000.
The
huge number of premium features, frequency of updating, and
install-it-and-forget-it aspect of AVG's Anti-Virus Free really do make
it the best of the best free antivirus programs available today
2. Avast! Free Antivirus
AVAST Software's avast! Free Antivirus most certainly deserves to be
on any list of the best free antivirus programs. avast! Free Antivirus
has fully functioning antivirus and antispyware engines protecting your
PC from threats from the Internet, your files, emails, and even instant
messages.
avast! Free Antivirus supports Windows 7, Windows Vista, Windows XP and Windows 2000.
One
big reason I included avast! Free Antivirus as a best free antivirus
program is because of its "heuristics engine" which can detect
previously unknown viruses and other malware. I also like the fact that
AVAST has been making this antivirus product since 1988 and is often
cited as the most installed antivirus product.
Tip:
During the avast! installation, you're asked to install the free Google
Chrome browser. It's not required so if you're not interested just
uncheck the box. Also, you are required to register avast! to use it
more than 30 days but registration is free and pretty simple. You'll
also have to reregister once per year - again, for free.
3. Microsoft Security Essentials
threats: if the icon next to y
Security Essentials from Microsoft is definitely one of the best free
antivirus programs available right now. Microsoft is relatively new to
the antivirus game but don't let that scare you - Security Essentials is
a fantastic antivirus program that protects you from all sorts of
malware, updates automatically, and is incredibly easy to use.
Microsoft Security Essentials supports Windows 7, Windows Vista and Windows XP.
Two
of the biggest reasons I added Microsoft Security Essentials to this
list of the best free antivirus software is because it's directly from
Microsoft and also because it's very easy to see if you're computer is
secure from our clock is green, you're in
good; if it's red, something is wrong.
4. Comodo Antivirus
Comodo Antivirus from Comodo Security Solutions is another excellent
program, easily one of the best free antivirus options out there. As of
this writing, Comodo Antivirus bills itself as the "Best Antivirus on
the Market. Guaranteed." due to its proprietary Defense+
technology. Comodo Antivirus also protects you from several threat
sources, just as most of the other best free antivirus programs on this
list do.
Comodo Antivirus works on Windows 7, Windows Vista and Windows XP.
Comodo Antivirus is easily one of the best free antivirus solutions solely because of its Defense+
technology that, by default, assumes unknown files are threats instead
of safe. That sounds like it might cause problems but Comodo Antivirus
utilizes some other technologies to make the whole process silent but
still very effective.
5. Avira Antivir Personal
Avira AntiVir Personal protects you from viruses, Trojans, worms,
spyware, adware, and various other kinds of malware, making it a fully
functional antimalware tool and certainly one of the best free antivirus
programs.
Avira AntiVir Personal works on Windows 7, Windows
Vista, Windows XP and Windows 2000. Avira also makes a version of
AntiVir Personal for UNIX.
The scope of malware that Avira
AntiVir Personal can keep you safe from is alone enough to make it one
of the best free antivirus software programs but the heuristics and ease
of use add to its value too. The only things I didn't like about Avira
AntiVir Personal was the configuration you have to complete after
installation which might be difficult if you're a computer novice.
Tip:
You're asked to register during the Avira AntiVir Personal installation
but it's optional. Just uncheck the box and continue with the install.
6. Panda Cloud Antivirus
Panda Cloud Antivirus protects you from several kinds of malware
threats - viruses, worms, Trojans, adware, and more - just like all the
other free antivirus programs in this list.
What makes Panda Cloud Antivirus one of the best
free antivirus programs is that it does its job from "the cloud"
meaning the hard antivirus work that typically slows down a computer is
done on computers elsewhere on the Internet, freeing up your computer to
work like it should and protecting you from malware even better.
Panda Cloud Antivirus supports Windows 7, Windows Vista and Windows XP.
Tip:
Panda Cloud Antivirus tries to install a toolbar and set Yahoo! as your
browser's home page during the installation process so uncheck the
boxes before continuing if you don't want them. Neither are required to
use Panda Cloud Antivirus.
7. Immunet Protect FREE
Immunet Protect FREE is a unique, cloud-based antivirus program, much
like Panda Cloud Antivirus. Immunet Protect FREE protects your computer
from bots, worms, viruses, Trojans, keyloggers, and spyware.
Immunet Protect FREE works on Windows 7, Windows Vista and Windows XP. You must also be connected to the Internet at all times.
I
think Protect FREE from Immunet is one of the best free antivirus
programs for several reasons: you never have to update it, it has
completely free telephone based support, and it can be run alongside
some of the other best free antivirus tools like AVG Anti-Virus Free,
Microsoft Security Essentials, and avast! Free Antivirus, increasing
your overall protection!
8. Digital-defender Antivirus
digital-defender Antivirus isn't a popular antivirus program but it
should be. It's certainly one of the best free antivirus software
programs you'll find. It's a full antivirus and antispyware program and updates on a daily basis.
digital-defender Antivirus supports Windows 7, Windows Vista and Windows XP.
The
relatively small installation size, daily virus definition updates, and
full antispyware features make digital-defender Antivirus one of the
better tools in my collection of the best free antivirus programs.
9. PC Tools Antivirus Free
PC Tools AntiVirus Free offers basic protection against viruses and
other malware. While not my favorite, AntiVirus Free is still one of the
best free antivirus programs you'll find.
PC Tools AntiVirus Free works on Windows 7, Windows Vista and Windows XP.
The
biggest problems I have with PC Tools AntiVirus Free are the reminders
throughout the program that there's a not-so-free version that you
should upgrade to. To be fair, you probably won't notice it since the
program runs silently in the background to protect you from viruses. I
probably find it annoying because most of the features available in the
upgrade are included for free in some of the higher rated best free
antivirus programs above.

MikroTik RouterOS is the operating system of MikroTik
RouterBOARD hardware.
It can also be installed on a PC and will turn it into a router
with all the necessary features - routing, firewall, bandwidth
management, wireless access point, backhaul link, hotspot
gateway, VPN server and more.
