What is DSLR Camera

Most digital single-lens reflex cameras (digital SLR or DSLR) are digital cameras that use a mechanical mirror system and pentaprism to direct light from the lens to an optical viewfinder on the back of the camera.
The basic operation of a DSLR is as follows: for viewing purposes, the mirror reflects the light coming through the attached lens upwards at a 90 degree angle. It is then reflected three times by the roof pentaprism, rectifying it for the photographer's eye. (Note that the diagram below incorrectly shows a non-roof pentaprism.) During exposure, the mirror assembly swings upward, the aperture narrows (if stopped down, or set smaller than wide open), and a shutter opens, allowing the lens to project light onto the image sensor. A second shutter then covers the sensor, ending the exposure, and the mirror lowers while the shutter resets. The period that the mirror is flipped up is referred to as "viewfinder blackout". A fast-acting mirror and shutter is preferred so as to not delay an action photo.
All of this happens automatically over a period of milliseconds, with cameras designed to do this 3–10 times per second.
DSLRs are often preferred by professional still photographers because they allow an accurate preview of framing close to the moment of exposure, and because DSLRs allow the user to choose from a variety of interchangeable lenses. Most DSLRs also have a function that allows accurate preview of depth of field.
Many professionals also prefer DSLRs for their larger sensors compared to most compact digitals. DSLRs have sensors which are generally closer in size to the traditional film formats that many current professionals started out using. These large sensors allow for similar depths of field and picture angle to film formats, as well as their comparatively high signal to noise ratio.
The term DSLR generally refers to cameras that resemble 35 mm format cameras, although some medium format cameras are technically DSLRs.

What is Website

A website (also spelled Web site) is a collection of related web pages, images, videos or other digital assets that are addressed relative to a common Uniform Resource Locator (URL), often consisting of only the domain name, or the IP address, and the root path ('/') in an Internet Protocol-based network. A web site is hosted on at least one web server, accessible via a network such as the Internet or a private local area network.
A web page is a document, typically written in plain text interspersed with formatting instructions of Hypertext Markup Language (HTML, XHTML). A web page may incorporate elements from other websites with suitable markup anchors.
Web pages are accessed and transported with the Hypertext Transfer Protocol (HTTP), which may optionally employ encryption (HTTP Secure, HTTPS) to provide security and privacy for the user of the web page content. The user's application, often a web browser, renders the page content according to its HTML markup instructions onto a display terminal.
All publicly accessible websites collectively constitute the World Wide Web.
The pages of a website can usually be accessed from a simple Uniform Resource Locator (URL) called the homepage. The URLs of the pages organize them into a hierarchy, although hyperlinking between them conveys the reader's perceived site structure and guides the reader's navigation of the site.
Some websites require a subscription to access some or all of their content. Examples of subscription websites include many business sites, parts of news websites, academic journal websites, gaming websites, message boards, web-based e-mail, social networking websites, websites providing real-time stock market data, and websites providing various other services (e.g. websites offering storing and/or sharing of images, files and so forth).

Four parts to a website:  
1.
Domain registration: You need to register your domain name (yourcompany.com) with a registrar. The price for this varies quite a bit. We include this as part of our web package and we will work with you to find an acceptable domain name that has not been reserved as well as taking care of the registration process. This will reserve “yourname.com” for you. You can reserve it for ten years if you wish although yearly renewal is part of our low annual fee.
2.
You need a website. That's what we do, as you know, from our website information. We design and build custom, completely personal websites meeting your criteria. We host and maintain all our websites at one low annual rate.
3.
You need a place to host your website. This is space on a webserver. All websites we design, maintain and host are on our server in a secure building in Texas. 99% uptime is guaranteed as well as the security of your information. All information is backed up daily to prepare for any emergency.
 We offer web design/hosting that we administer for you. This means that since our hosting programs include complete e-mail service, we would set up the email at the server side and maintain that function for you. Add, delete or change addresses as often as you need, its all part of the package. We are also there to help setting up the email at your computer(s). It is very professional to have your email be: someone@yourwebsite.com .  
4.
You will need an Internet Service Provider, (ISP). If you have internet access already this will do the trick. These are the companies like "Earthlink", "AOL" and a multitude of others with prices that range from $5.00 a month and up. You would need this to view your website and most importantly it is the gate to receive your (somename@yoursite.com) Email. This is the only thing you will have to take care of on your own although we will make reccomendations based on what is available in your area.
