C-mount lenses provide a male thread which mates with a female thread on the camera. The thread is nominally 1.000 inch (25.4mm) in diameter, with 32 threads per inch, designated as "1-32 UN 2A" in the ANSI B1.1 standard for unified screw threads. The flange focal distance is 17.526 millimetres (0.6900in) for a C mount.
Merely to say that a lens is "C-mount" says very little about the lens' intended use. C-mount lenses have been made for many different formats. C-mount lenses are built for the 8mm and 16mm film formats and the 1/3", 1/2", 2/3", 1", and 4/3" video formats, which corresponds to a range of image circles from 5 to 22mm diameter, approximately.
This is no trivial difference. For example, for the 4/3 format, a 12-mm lens is a wide-angle lens and will have a retrofocus design. For the 2/3inch format, a 12mm lens is "normal" and can have a simple and fast double Gauss layout. For the 1/3inch format, a 12-mm lens is long and can have a telephoto design.
Mounting takes place before a computer can use any kind of storage device (such as a hard drive, CD-ROM, or network share). The user or their operating system must make it accessible through the computer's file system. A user can only access files on mounted media.
Overview
A mount point is a physical location in the partition used as a root filesystem. Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives. As of 2013, magnetic media are still the most common and are available as hard disk drives and, less frequently, floppy disks. Before any of them can be used for storage, the means by which information is read and written must be organized and knowledge of this must be available to the operating system. The organization is called a filesystem. Each different filesystem provides the host operating system with metadata so that it knows how to read and write data. When the medium (or media, when the filesystem is a volume filesystem as in RAID arrays) is mounted, this metadata is read by the operating system so that it can use the storage.

C-mount lenses provide a male thread which mates with a female thread on the camera. The thread is nominally 1.000 inch (25.4mm) in diameter, with 32 threads per inch, designated as "1-32 UN 2A" in the ANSI B1.1 standard for unified screw threads. The flange focal distance is 17.526 millimetres (0.6900in) for a C mount.
Merely to say that a lens is "C-mount" says very little about the lens' intended use. C-mount lenses have been made for many different formats. C-mount lenses are built for the 8mm and 16mm film formats and the 1/3", 1/2", 2/3", 1", and 4/3" video formats, which corresponds to a range of image circles from 5 to 22mm diameter, approximately.
This is no trivial difference. For example, for the 4/3 format, a 12-mm lens is a wide-angle lens and will have a retrofocus design. For the 2/3inch format, a 12mm lens is "normal" and can have a simple and fast double Gauss layout. For the 1/3inch format, a 12-mm lens is long and can have a telephoto design.
