What Is Web Hosting?
Laptop Battery If you want to take part in the internet as a business,
information resource, directory, or as a hobbyist wanting to share
data, information and knowledge with the many people and
communities on the internet, you have to contain this in a central
spot on the internet. You have to own a piece of space in
cyberspace.
established web hosting provider sometimes hosts up to thousands of websites. For that reason, a web hosting company need many web servers (essentially, these are computers) to store the website. And all these web servers are connected to the Internet through high speed Internet connection and housed in a physical building called data center In order to guarantee all the web servers are safe, secure and fully operational all time, 7 environment with fire protection, virus detections, computer data backup, redundant power backup and complete disaster recovery capabilities.
Thinkpad Web hosting empowers you and anyone with a computer and internet
connection to own a piece of cyberspace. In your space, you can
have news, bulletins, documents, data, files (your web site) and
your own post office (mail server) to accept mail, all in the
context of you or your business. This is your space and to get this
space you either have to own a piece of the physical internet with
a network connection to the internet backbone and computer(s)
operating as server(s) offering access to your files and post
office, for people on the internet to view your web site or send
and receive email with you.
> Choosing a Web Hosting Plan Choosing a Web Hosting Plan Overview There are approximately 100 million Web sites on the Internet. They are "hosted" on computers (called web servers) all over the world. The web server (computer) where your Web site's information, photos, etc. reside, may be located in a home or office, but ideally, in a secure data center, and maintained by a "web host" (like WestHost). Web hosting clients simply upload their Web sites to either a shared web server (where many other clients are also hosting), or a dedicated web server (where the entire server is their own), which the web host maintains to ensure the Web site is always available, and can be accessed quickly (a fast download).
Microsoft The cost of owning a direct connection to the backbone and a
server dedicated to a web site and email is out of reach for the
average business and especially general members of the internet.
Even running a web site and mail server on your own computer when
it is connected to the internet requires a lot of technical ability
and knowledge. The internet itself has to be your business for
either of these options to be viable.
Dedicated Server An advanced form of web hosting where the customer generally has complete control over the server. Dedicated Servers are typically housed in data centers. Dedicated servers may be compared to shared web hosting servers; where in shared hosting you find the web hosting company administering and control the server, a dedicated server is typically controlled by the server's owner and he or she controls which websites are hosted on the server.

Laptop Computers In our modern society, for every person in business or with a
career in most industries today, it is imperative to have a place
in cyberspace, not just to be competitive but to survive. Web
hosting companies were born out of this great need to provide an
environment for the masses to own a piece of cyberspace, to offer
an environment where people could have their piece of cyberspace on
the internet 24/7 without the great cost. Web hosting companies
developed a model where they could split up areas on the servers
connected to the backbone and ?rent? this space, cutting the costs
across many people sharing the server and backbone connection to
the internet.
Whata s happening When a website is requested through a web browser (Internet Explorer, Firefox, etc), the request is first sent to the computer's Internet Service Provider (ISP) which contacts the domaina s name servers to look up the location (IP address) of the web hosting server. Caching occurs when the web hosting server at the IP address location no longer hosts the website, but a visitor's web browser still attempts to connect to that server to retrieve the web page. This happens because the web browser and the computer's operating system keeps a list of already looked up IP addresses, and it refers to that list for future IP address look ups. ISPs also keep their own IP address list as well. The purpose of this is to speed up web page loading times, and to reduce the traffic on the Internet. Unfortunately, this can lead to delays during name server changes. The images below shows what happens when there is no caching and what happens when there is caching.
Laptop Computer In a web-hosting environment, you are offered a web site to
place your files, data, documents, and bulletins for people to
access with their web browser and an email server for you to send
and receive email messages. The web host will also provide you a
means to get an address for people to get to your web site with a
web browser and post email to you.

Desktop Computer To obtain space in a web hosting environment you become a member
and agree to terms and conditions of renting the space ? just as if
you were to rent a house or commercial premises for your business.
Once you agree and become a member, you are given an access code, a
key, to your piece of cyberspace. This key, in the form of a login
and password, allows you to connect to the web hosting server and
up-load (transfer to) your web site so it can be accessed on the
internet. Your login and password is also used to connect to a mail
server to create and administer mailboxes to send and receive email
for you, your staff, or family members.
Notebooks Just like when you rent a house or commercial premises for your
business, you have so many rooms, bathrooms, and floor space to
use. In a web-hosting environment, your area is defined as disk
space and network transfer.
Lenovo Disk space is measured in Megabytes (MB) or Gigabytes (GB).
Megabyte roughly means 1,024,000 characters and Gigabyte roughly
means 1,024 Million characters. Imagine a character as one key on
your key board. These amounts determine how many files, documents,
or data you can have on your web site.
Hard Drive Network Transfer is also measured in Megabytes or gigabytes
which determines how much data (how many of your files, documents
or data) can be downloaded (transferred to) people accessing your
web site. The more people, or the more data each person accesses on
your web site the more data is transferred on the network.
Travelstar The more disk space and network transfer you use the greater
percentage of the web-hosting environment you are using ? therefore
the higher the rent.
Gateway Just as no office building and home is the same, neither is
every web-hosting environment. Some offices have stairs, others
have lifts, some houses have ensuites, swimming pools, and
gardens, ? and others do not.
Web-hosting environments are much the same, some offer bare
structures to do just the basics and others offer an array of
features and facilities to help you do just about everything you
could ever need or want. Some of the features and facilities likely
to be offered are ranges of software to use, components, databases,
and server side script processing.
Laptop Parts The similarity of renting an office or home to renting space in
a web-hosting environment is even more similar. With some buildings
a gardener and/or a guard is available to look after the gardening
or provide security. In a web-hosting environment, you have support
people to help you do what you need to do on your web site to make
it grow and there are server administrators to protect and secure
your web-hosting space.
Software When you rent a building there are key parts needed to work or
live in the space, like rooms, offices,
kitchens, toilets, and bathrooms.
In your web-hosting environment, you will find equally important
components that are required to make the space workable. The core
components in a web-hosting environment are:
Hard Drives Web Server
Electronics The web server is a relatively simple piece of software that
accepts requests over HTTP (Hypertext Transfer Protocol) and
delivers HTML pages and Image files.
Canon FTP Server
Desktop Pc FTP is the means of which a web master can transfer files to and
from the server. To put your HTML and image files on a server you
will generally use FTP to upload (transfer to) your files to the
server running the web server.
Desktop Computers Mail Server
Think Pad The mail server consists of two parts POP (Post Office Protocol)
and SMTP (Simple Mail Transfer Protocol). POP is where email is
received into your mailbox and SMTP is what is used to send and
receive email between mail servers.
Repair Database Server
Data Recovery If you are using server side scripting on your web server (you
use something like Microsoft Internet Information Server) then
instead of providing ?static? data only on web pages you can
provide data from a database allowing your users to search and view
the data in different and dynamic way. Also, a Database server is
used to gather data from visitors to your site; orders, feedback,
discussions and the like.
Cisco Each one of the above components are software programs running
on servers in the web-hosting environment. You can interact with
each of these with special software programs you use on your
computer. The main ones being:
Keyboard Web Browser
Monitor When viewing the web you use a web browser like Internet
Explorer. Many web hosting companies provide a ?Control Panel? to
administer your web host account, which you use with your web
browser. Most allow you to configure most aspects of your account
using a simple web browser.
Desktop Web site/page editor
Infosys Today many web servers allow editing of WebPages over HTTP
(hypertext transfer protocol) based on Microsoft FrontPage
technology. These special editors allow you to essentially look at
your web site as if you were using a web browser and edit the pages
directly as you see them using WYSWIG (What you see if what you
get) technology. Most web hosting environments support this, and if
you are starting out, make sure it is available. One tip: make sure
the web host providing this really does understand this technology
? it is the main area of which many hacks and security intrusions
occur.
Refurbished Laptops FTP Client
Wipro This is a very simple piece of software that allows you to view
the server folders and files in your web host account as if they
were files and folders on your own computer. You can then drag and
drop files between you computer and your web host account.
Lap Top Email Client
Refurbished If you are on the internet you would already be using an email
client to send and receive your email. The most common are Outlook
Express, Eudora and Web based mail clients like Hotmail.
Memory Database Administration Client
Intel The most common databases used with web servers are Microsoft
SQL Server (available only on Windows) and MySQL (commonly found on
Linux and UNIX but also available on Windows). SQL Server comes
with it's own administration client where you can view your
databases, edit them, backup data and do all the administration
functions you need. MySQL has an active online community where
there is a range of administration clients available.
As400 Choosing a web host is, again, similar to choosing a house to
live in or commercial premises to
do
business. You need to define what it is you require:
how much space you need and what features and facilities you
need.
Averatec If you have been reading this article because this is new to
you, then it is likely at this stage you only need minimal space
and basic facilities. Once you have worked with the basic
facilities you will learn more and become aware of greater
facilities and features and then you can simple move from one web
?hosting environment to another ? paying more or paying less.
Moving in cyberspace is much easier, faster, and more seamless than
physically moving house or commercial premises.
Hardware Initially you may use the web-hosting environment offered by
your ISP (internet Service provider), the company you use to
connect to the internet. But remember these companies main business
is connecting many thousands of people to the internet ? not
managing web hosting environments. You will generally find they
offer less than basic facilities and minimal space.
Dual Xeon If you are just starting out with your first web site the first
major choice you will be faced with is ?Unix? or ?Windows?. For a
person just starting out on the internet, both are equally capable
and will offer the facilities you need to have your place in
cyberspace.
Storage If you have a web designer or technical person to help you, you
only need to consider how much space you really need. With this
simple idea in mind, when you are just starting out, owning your
piece of cyberspace will not cost anymore than $8 per month. Many
web-hosting companies will offer what you need for as little as $3
per month (usually paid yearly).
Seagate If you are going alone and doing it all yourself you may want to
consider an account with a web hosting company that offers and
prides itself on it's support and customer service, 24/7 support
access and the experience, knowledge and skill of it's server
administrators. Remember, these are the gardeners and the guards
who take care of your environment.
Computer Sales Web hosting is very simple and straightforward an once you
obtain your space in cyberspace you will never want to let it go
and you can easily move it where you want as a turtle carries it's
shell on it's back. Always remember you are not stuck in the first
web-hoisting environment you choose.
Computer Hardware Web hosting is your space in cyberspace and it is imperative to
have a place in cyberspace in our modern society, just as it is to
have an office to do business.
