FTP
A protocol developed to enable the transfer of files across a network. It provides a reletively insecure username and password security but has been more recently enhanced to allow for SSL encryption to provide a secure password exchange.
To some extent the use of FTP has been superceeded by SFTP (a component of SSH) or the secure file transfer protocol. |

SDRAM
A generic name for various kinds of dynamic random access memory: DRAM that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM is rated in MHz rather than in nanoseconds (ns). This makes it easier to compare the bus speed and the RAM chip speed. You can convert the RAM clock speed to nanoseconds by dividing the chip speed into 1 billion ns (which is on...

JPEG
A compressed graphics format specifically designed for photographs. Itīs name an acronym that stands for Joint Photographic Experts Group. It works by changing the images data from colours to frequencies (that represent detail) using a FFT and then discarding some of the high detail data - the resulting image is slightly blurry but this is barely noticable by the human eye and represents a significant saving of space.

where
Locate the binary, source, and manual page files for specified commands/files. The supplied filenames are first stripped of leading pathname components and any (single) trailing extension of the form .ext (for example, .c). Prefixes of s. resulting from use of source code control are also dealt with. where then attempts to locate the desired program in a list of standard Linux directories (e.g., /bin, /etc, /usr/bin, /usr/local/bin/, etc.).

Depth-of-field
The area of sharpness in a picture, extending in front of and behind the plane of the subject, that is most precisely focused by the lens.
You can control depth of field by varying three factors: 1) the size of the aperture 2) the distance of the camera from the subject 3) the focal length of the lens. If you decrease the size of the Aperture, the depth of field increases; if you focus on a distant subject, depth of field will be greater than if you focus on a near subject; and if you... |
