In operating systems, the term terminal host denotes a time-sharing computer or multi-user software providing services to computer terminals, or a computer that provides services to smaller or less capable devices,[1] such as a mainframe computer serving teletype terminals or video terminals.

Like Flickr, 500px is a popular social network for photographers looking to share their best photos. It doesn't exactly compare to some of the alternatives discussed above because unfortunately, you can't directly link to photos if you want to share them elsewhere, but it's a fantastic option for photographers looking to show off their work and maybe make a little money from it.
To host a website on the internet, an individual or company would need their own computer or server.[7] As not all companies had the budget or expertise to do this, web hosting services began to offer to host users' websites on their own servers, without the client needing to own the necessary infrastructure required to operate the website. The owners of the websites, also called webmasters, would be able to create a website that would be hosted on the web hosting service's server and published to the web by the web hosting service.
Middle English ost, host "person who receives guests, guest," borrowed from Anglo-French oste, hoste, going back to Latin hospit-, hospes "guest, visitor, person receiving guests," going back to dialectal Indo-European *ghosti-pot- (whence probably also Old Church Slavic gospodĭ "lord, master"), from *ghost-i- "outsider, guest" + *pot- "one in control, master" — more at guest entry 1, potent entry 1
You can easily create folders and sub-galleries to organize your photos, either on your desktop or your smartphone. To share a photo, you just have to right-click on it, copy the link, and paste it wherever you want to share it. You can also import your contacts and directly email them the link to your photo or entire gallery. If you allow them to, visitors can even download your photos or albums.
You don’t need to create an account to upload images to Use, but you can make your photos public or private. Use offers a photo editor and image re-sizer, and you can also organize your photos into albums. The site doesn’t give direct links, but you can right-click on your photos to copy the image URL, or you can use the site’s social sharing buttons to post your uploads to social media sites.
ImageShack has a non-premium account option and a free 30-day trial to check out the premium features. This image hosting alternative has a great looking interface, somewhat similar to how Pinterest showcases its images in a pinboard-style layout. You can use it to upload as many high-res photos as you want, create albums, organize everything with tags and discover featured photos from other users for inspiration.
The host may also provide an interface or control panel for managing the Web server and installing scripts, as well as other modules and service applications like e-mail. A web server that does not use a control panel for managing the hosting account, is often referred to as a "headless" server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.).
