|
client
|
computers that can connect to the internet for short periods of times, such as to check email, update Facebook, or shop at Amazon. |
|
|
server
|
computers that are always connected to the internet. Servers hold the information seen on webpages and they "serve" up that information through different types of software. |
|
|
web server
|
hold the files, videos, etc. that will be seen on the internet. Provide the information to users, while allowing you to have the ultimate control over how your information is presented and used. |
|
|
shared web host
|
Server runs your site in the same place as many other sites. Must share resources, processing power, memory, and hard drive space with other users. Economical, but if one site has problems, it can affect others. Less secure, less power, and less customization. Fewer rights to install your own software. |
|
|
virtual web host
|
Server runs in a virtual environment. Guaranteed amount of processing power, memory, and hard drive space only to be used for you. Can have root access, but still will be sharing memory, hard drives, and other resources. If one server crashes, does not impact the others. Allows for more custom software than shared. |
|
|
cloud web host
|
Server runs solely on a cloud or network of computers. If one fails, another takes over your site so is more efficient than the previous two. Pay for what you use |
|
|
dedicated hosting
|
Your very own server. You share nothing and have root access so you can install anything. Most expensive type of hosting, but most flexible. |
|
|
domain name
|
A unique name for a website that must be registered. Example: Microsoft.com |
|
|
sub domain
|
The section of a web address that goes before the domain name. Example: Support.Microsoft.com. Used for quicker access to a specific place in a website. |
|
|
top-level domains
|
One of the domains at the highest level in the hierarchical Domain Name System of the internet. Examples: .com = company; .edu = educational organizations; .org = an organization, typically non-profit; .net = open to anyone; .gov = governmental; .mil = US Military |
|
|
FTP
|
Stands for File Transfer Protocol. Is used to send files to a server. |
|
|
absolute reference
|
The location of the item is coded as if we were typing the full address into a browser URL bar. For example, http://www.wgu.edu/online_it_degrees/bachelor_degree_programs. Use this type of reference when linking to a site outside of your site. This will only work when you have an internet connection. |
|
|
relative reference
|
Location of the item is coded in relation to the current page. So if there the main webpage is in the root directory and there is a picture in an images folder in that same directory, we could code it to say to use the file at the location "images/filename.jpg". This type of reference can be cumbersome if you have a lot of folders. Sometimes it may be necessary to write the code to look for a file a level up from the current document, which would look like "../images/filename.jpg". Use this type of linking if you know the structure of your site will remain constant. |
|
|
root relative reference
|
Looks exactly like the absolute reference except it doesn't include the domain name . Example: /online_it_degrees/bachelor_degree_programs. Note how it starts with a / . Starts in the web root folder for whatever the website is and moves to the designated folders to look for the files from there. This type of reference is good to use when the folder structure on your site is complicated because you don't need to write the code to look a level up or to worry about many cumbersome folders. |
|
|
requests
|
Clients request information from a website and servers receive those requests and issue responses by "serving" up the requested information. |
|
|
protocols
|
Handle the communication between the client and the server, such as HTTP, HTTPS, or FTP |
|
|
Password Protection
|
Can help you provide specific information to only specific individuals while others cannot access it. Can be used to set a basic security level for any folder on your website. |
|
|
FTP Client
|
An application, such as FileZillia, used to transfer files from a local computer to the web server. |
