Computer that allows downloading (and uploading in some cases) of files by the use of file transfer protocol (FTP) over the internet. There are over a thousand FTP sites with hundreds of thousands of text, graphics, sound, and video files freely available to anyone. However, a FTP site is not a website because its data cannot be displayed like a webpage. See also anonymous FTP.
Scientific tools for making observations include a microscope, which is a tool used to see very small objects. In your science lab you use a compound microscope to see cells in 2-D, but a scientist can use a scanning electron microscope to view tiny objects in 3-D.
Pliers are some of the handiest tools to have around because they can be used for cutting, twisting, clamping and more. When we look for a pair of pliers to purchase, we always take note of the handle material, how tight the hinge feels, how precise the cutting surface or teeth are in the jaws and of course the over all quality of the tool.
