General protection fault (GPF, sometimes seen as general protection error) the name of an error caused when an application program (for example, Microsoft Word or the Netscape Web browser) tries to access storage that is not designated for its use. An operating system (such as Windows 95) manages the use of random access
DEFINITION of File Server Resource Manager
File Server Resource Manager is a feature set in the File and Storage Services server role in Windows Server that helps administrators classify and manage stored data in file servers.
What is Big Data
Big Data usually includes data sets with sizes beyond the ability of commonly used software tools to capture, curate, manage, and process the data within a tolerable elapsed time. Big data sizes are a constantly moving target, as of 2012 ranging from a few dozen terabytes to many petabytes of data in a single data set.
DEFINITION of backbone
A backbone is a larger transmission line that carries data gathered from smaller lines that interconnect with it.
1) At the local level, a backbone is a line or set of lines that local area networks connect to for a wide area network connection or within a local area network to span distances efficiently (for example, between buildings).
DEFINITION of distributed file system
A distributed file system is a client/server-based application that allows clients to access and process data stored on the server as if it were on their own computer. When a user accesses a file on the server, the server sends the user a copy of the file, which is cached on the user’s computer while the data is being processed and is then returned to the server.
DEFINITION of ATM
ATM (asynchronous transfer mode) is a dedicated-connection switching technology that organizes digital data into 53-byte cell units and transmits them over a physical medium using digital signal technology. Individually, a cell is processed asynchronously relative to other related cells and is queued before being multiplexed over the transmission path.
DEFINITION of block cipher
A block cipher is a method of encrypting text (to produce ciphertext) in which a cryptographic key and algorithm are applied to a block of data (for example, 64 contiguous bits) at once as a group rather than to one bit at a time. The main alternative method, used much less frequently, is called the stream cipher.
DEFINITION of digital certificate
A digital certificate is an electronic “passport” that allows a person, computer or organization to exchange information securely over the Internet using the public key infrastructure (PKI). A digital certificate may also be referred to as a public key certificate.
DEFINITION of Ethernet
Ethernet is the most widely-installed local area network ( LAN) technology. Specified in a standard, IEEE 802.3, Ethernet was originally developed by Xerox from an earlier specification called Alohanet (for the Palo Alto Research Center Aloha network) and then developed further by Xerox, DEC, and Intel. An Ethernet LAN
DEFINITION of bootable floppy
A bootable floppy is a diskette containing a back-up copy of your hard disk master boot record (MBR). In the event that the master boot record becomes “infected” by a boot virus, having a bootable floppy will allow you to load it back onto your hard disk. (Otherwise, you may have to reformat your hard disk which first erases
