I-J-K-L - What Does That Motherboard Terminology Mean?
IDE (Integrated Device Electronics):
It is the most widely-used hard drive interface on the market. The fancy name refers to how the IDE technology "integrates" the electronics controller into the drive itself. The original IDE standard could only support hard drives containing up to 540 MB of data. The new standard, EIDE (Enhanced-IDE), supports hard drives with over 50 GB of data and allows for data transfer rates that are over twice as fast as the original IDE.
IEEE 1394:
Also known by the trademarked names of FireWire and i.LINK, IEEE 1394 is a standard for high-speed transfer of digital information. It is one of the most popular standards for connecting computers and other digital devices to various components and peripherals, such as external hard disk drives, scanners and digital video camcorders.
Input / Output (I/O):
I/O (Input / Output) often refers to the connection or interface between your computer system and other internal or peripheral hardware devices.
Industry Standard Architecture (ISA):
ISA (Industry Standard Architecture) is a standard system bus which was introduced as an 8-bit bus with the original IBM PC in 1981. This was later expanded to 16-bit with the IBM PC/AT in 1984. ISA slots have been phased out. This is a 16bit expansion slot that's now almost extinct. Very few new cards are available in this format. Usually 386, 486, and PI motherboard have these slots.
Jumper:
It is a small block (approx .250" wide x .312" long x .125" thick with two holes running lengthwise which are connected with a metal structure), or the functionally equivalent electronic "interconnect"; used to enable, disable, or select operating parameter on a motherboard or other PCB by either electrically connecting two pins on the PCB (closed) or separating them (open - only one pin is covered or the jumper is removed).
Jumper Header:
it is a two pins or a series of two-pin groups where jumpers are used.
Level 1:
Mirroring and Duplexing:
Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.
Local-Area Network (LAN):
A LAN (Local-Area Network) is a computer network that connects PCs, workstations or other LANs and networks to enable data and device access and sharing. It is used to cover a small local area such as a home, office or small group of buildings. Current LANs are most likely to be Ethernet (wired) or Wi-Fi (wireless) based.
