What is Web
Hosting? Why do you need Web Hosting? |
|
|
|
You need web
hosting when you want to have a website.
A website will only be called a 'website' if everyone connected to the
internet is able to see it. They must be able to look at the text you have
written, the pictures you have posted and everything that you have placed
on your website! Just like every internet user will be able to read this
article, including you. |
|
|
|
Your website
is actually a collection of computer files (usually text files &
pictures). These files need to be store in a 'super' computer with high
speed internet connection. These computers are called servers. You will
put all your files in these servers. The guys who provide such
services are called web hosts, or web
hosting providers. They HOST your
website. |
|
|
|
The place
where they put their servers is called datacenter. A datacenter is simply
a room or a building. A datacenter provides fast internet connection to
the servers. It also has facilities such as security entrance, fire
protection, electricity backup ... for the purpose of keeping the server
safe, secure and running with minimum downtime. |

Server vs. Your Computer: |
|
|
|
A server is
quite different than a personal computer. Your personal computer will
usually have 1 processor, 1 hard disk drive and 1 power supply.
A powerful
server will usually have 2 or more processors. This allows the server to
execute faster and process more applications at the same time. |
|
|
|
A server will
also have a few hard disk drives to store its data. The same data is
always written to 2 disks for backup purposes. That's why no data will be
lost if one of the disk failed. The swappable feature of the hard disks
even allow a technician to remove and replace the failed hard disk drive
without turning down the server! |
|
|
|
Most servers will also have 2 power supplies. If one of them failed, the
other power supply keeps the server running without disruption. The power
supplies are also swappable so the failed power supply could be replaced
without the need to power down the server. |
|
|
|
A
server will need an internet connection that is a few hundred times faster
than ordinary DSL/Cable in order to serve many visitors simultaneously. So
why are we telling you all these? Because it is really a bad idea to host
your website with your computer and your DSL connection! :) |

Different Level of Web Hosting -
Shared Hosting (Virtual Hosting): |
|
|
|
Having a website on a server alone is a waste of resources. Unless you
have plenty of money to spend, we usually don't need a whole server to
host our site. Here we introduce to you the most common level of web
hosting - shared hosting (or virtual hosting). Depending on
the speed of the server, it could possibly host more than 1,000 sites
without any problem. The users on the same server will share the same
resources of it (disk space, bandwidth, memory, etc.). This makes web
hosting affordable because you pay a portion of the server fee instead of
the entire server. Our directory focus entirely on
shared hosting below20LE/month. Over 95% of websites of the internet are hosted on shared
hosting environment. |
|
|
|
Dedicated Server: |
|
|
|
When you choose to rent the entire server for you own use, then you are
using a dedicated server. In some cases, you can share a server
with another user and so you are using a semi-dedicated server. For
dedicated hosting, you actually rent the server from the web host and you
do not own the server. The web host owns it. Another common term for
dedicated hosting is managed hosting. |
|
|
|
Server Co-Location: |
|
|
|
You can choose to buy a server instead of renting it. You will then need
to place it in a datacenter. Server Co-Location means having your
server co-located at a datacenter by paying the datacenter a certain fee.
A datacenter provides your server with the greatest protection and most
important, high speed internet connection. |

|
Web Hosting Operating System -
Unix vs. Windows |
|
|
|
What is Operating System (OS)? |
|
|
|
We believe you are using Windows XP, Windows 98 or other versions of
Windows. |
|
|
|
Over 90% of personal computers are using Windows Operating System
(OS). Operating System is the most important software for your computer.
It takes care of many important tasks of your computer where in most cases
you aren't even aware of. For example, your OS is responsible for booting
up and shutting down your computer, handling your computer hardware (CPU,
memory, disk, modem ...), allow you to install other software, plus many
more. An operating system act as a platform for a computer. It
needs to be installed in a computer before any other software because it
is the core software. |
