7 Computer Tech Definitions

Group: Computer Tech

Topic: Computer Tech

#1. NAT - Network Address Translation (NAT). The process of modifying network address information in a data packet header while in transit across a router for the purpose of remapping a given address space into another. Allows you to hide your local IP addresses from the Internet.

Topic: Hardware

#2. MbPS - Megabits (mb) per second. A bit is either a 0 or 1 (a digit) and a byte is a string of 8 bits. 8 mbps (megabits per second) equals 1 MB/sec (megabytes per second). Therefore 54 mbps is equal to a max of 6.75 MB/second.
#3. SAN - A high speed network of storage devices availabe to all servers on a LAN or WAN

Topic: Non-Removable Storage Technology

#4. LUN - Logical Unit Number (LUN)
#5. RAID -

RAID is the acronym for a Redundant Array of Independent Drives. RAID specifies several "levels," 0, 1, etc. Different levels provide different options. One level allows you to combine multiple smaller drives into one, huge volume. Another level offers tremendous performance boosts by "striping" data across multiple drives such that reads and writes are split across the drives. If one drive fails, the other takes over until the bad drive is replaced. Once replaced, the RAID subsystem automatically restores the mirror.

Topic: Removable Storage Technology

#6. ISO Image - A disk image of an ISO 9660 file system usually with a .ISO extension. ISO stands for International Organization for Standardization (ISO) and standard 9660 describes a standard for storing data on a CD or DVD. An ISO image (or .ISO file) is a single computer file that is a copy of an existing file system (all files including all the filesystem metadata (boot code, structures, attributes, etc.). An ISO image can contain the entire contents of a CD or DVD.

Topic: WINS

#7. Windows Internet Name Service (WINS) -

Microsoft's implementation of NetBIOS Name Service (NBNS), a name server and service for NetBIOS computer names. Just as DNS serves up domain names, WINS serves up NetBios names and is particularly useful within a Microsoft-based network when or without the NetBIOS protocol installed. Use of WINS will decrease broadcast traffic.
