FILE TRANSFER
File transfer:File transfer is a generic term for the act of transmitting files over a computer network like the Internet. There are numerous ways and protocols to transfer files over a network. Computers which provide a file transfer service are often called file servers. Depending on the client's perspective the data transfer is called uploading or downloading. File transfer for the enterprise now increasingly is done with Managed file transfer. File transfer is a generic term for the act of transmitting files over computer network like the Internet.
Storage:
A data storage device is a device for recording storing information data. Recording can be done using virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs.
A storage device may hold information, process
information, or both. A device that only holds information is a recording
medium. Devices that process information data storage equipment may either
access a separate portable removable recording medium or a permanent
component to store and retrieve data.
File format:
is a standard way
that information is encoded for storage in a computer file. It specifies how
bits are used to encode information in a digital storage medium. File formats
may be either proprietary or free and may be either unpublished or open.
Some file formats are designed for very particular types of
data: PNG files, for example, store bitmapped images using lossless data
compression. Other file formats, however, are designed for storage of several
different types of data: the Ogg format can act as a container for different
types of multimedia, including any combination of audio and video, with or
without text (such as subtitles), and metadata. A text file can contain any
stream of characters, including possible control characters, and is encoded in one
of various character encoding schemes. Some file formats, such as HTML,
scalable vector graphics, and the source code of computer software are text
files with defined syntaxes that allow them to be used for specific purposes.
File formats
often have a published specification describing the encoding method and enabling
testing of program intended functionality. Not all formats have freely available
specification documents, partly because some developers view their
specification documents as trade secrets, and partly because other developers never author
a formal specification document, letting precedent set by other programs define
the format.[
