| 10base2 - An ethernet standard for cable. The 10 refers to its 10 Mbps bandwidth, the base to single channel baseband, and the 2 to its 200 meter effective range.... |
| 10baseT - An ethernet standard for cable. The 10 refers to its 10 Mbps bandwidth, the base to single channel baseband, and the T to Twisted pair. The cable uses... |
| 404 error - Error returned by a browser when it is unable to connect to a remote address. |
| 1-tier architecture - A simple form of standalone application architecture where everything resides in a single program. Contrast this to 2-tier and 3-tier architectures. |
| 1000BaseT - An extension of 100BaseT that runs 10 times faster than 100BaseT. It's theoretically capable of 1Gbps (1000Mbps) transmission speed, and requires Category... |
| 100BaseT - An extension of 10BaseT that runs 10 times faster than 10BaseT over copper wire. It's theoretically capable of 100Mbps transmission speed. The drawback... |
| 10Base5 - The original Ethernet specification, which is now more uncommon than 10Base2. It's also known as "thicknet." Cable speeds are typically up to 10Mbps. 10Base5... |
| 128-bit Operating Systems - Operating systems may eventually be 128-bit. The ability to address 128 bits of memory space is something that may someday be necessary for huge databases,... |
| 128-bit Video - The bits referred to here describe the bus between the GPU and the video memory. Typically, larger buses mean faster video, but it also depends on the... |
| 1394 IEEE standard - A serial connection technology that promises to speed data at 200-800Mbps and up. Digital video camera manufacturers and Apple have embraced this connection... |
| 16-bit Operating Systems - DOS and Windows 3.x are 16-bit operating systems. They are limited in complexity and suffer instability and slow speed (compared to 32-bit OSes) when run... |
| 2-tier architecture - Applications that have a code base (1-tier) separate from the database management system (1-tier), such as using Delphi to interact with Microsoft SQL... |
| 2.5G - Second generation wireless technology (2G) with incomplete third generation (3G) technology added to it. |
| 3-tier architecture - This architecture splits the user interface from the application logic. Servers handle the database management and application logic. This works out to... |
| 32-bit Chips - This type of processor can run a 32-bit OS, such as Windows NT or some versions of UNIX. You can also run a 16-bit or lesser OS, but performance is not... |
| 32-bit color depth - Anything that supports 32-bit color supports over four billion different colors (2^32, or 4,294,967,296 to be exact). Graphics cards are supporting up... |
| 32-bit Memory Module - DRAM modules with 32 separate data lines. 72-pin SIMMs are 32-bit memory modules. Using 32-bit modules with 64-bit memory interfaces requires pairing ... |
| 32-bit Operating Systems - Windows NT, OS/2, and some flavors of UNIX are 32-bit operating systems. Windows 95 is a 32-bit operating system running on top of a 16-bit operating system... |
| 32-bit processor - This type of processor can run a 32-bit OS, such as Windows NT or some versions of UNIX. You can also run a 16-bit or lesser OS, but performance is not... |
| 32-bit Video Cards - These are generally older cards that were only capable of addressing 1 MB of RAM. The 32 bits refers to the amount of information that can be transferred... |
| 3DNow! - A set of 3D/multimedia floating point instructions first introduced in AMD's K6-2 processor. Newer processors from AMD support the instructions as well.... |
| 48-bit color depth - Some scanners support 48-bit color, which offers the ability to identify over 281 trillion (2^48) colors. Such color differences may be imperceptible to... |
| 56Kflex - This was one of the two competing 56Kbps modem standards. It was developed by Rockwell and Lucent, and had more marketshare than USR's X2 technology due... |
| 64-bit Chips - A processor that can run a 64-bit OS. The DEC Alpha is 64-bit, and so are Intel's Itanium and AMD's Opteron and Athlon 64 processors. The 386, 486, and... |
| 64-bit Memory Module - DRAM modules with 64 separate data lines. SDRAM and DDR DIMMs are an example of 64- bit memory chips. |
| 64-bit Operating Systems - An operating system that is programmed to run on 64-bit processors. Some flavors of UNIX--and now Linux--are 64-bit operating systems designed to run on... |
| 64-bit processor - A processor that can run a 64-bit OS. The DEC Alpha is 64-bit, and so are Intel's Itanium and AMD's Opteron and Athlon 64 processors. The 386, 486, and... |
| 64-bit Video Cards - Most current video cards have at least a 64-bit bus between the GPU and the video memory. The first 64- bit cards must had at least 2 MB of memory, up... |
| 8 bits - A measure of memory. 8 bits make up 1 byte, and offer 256 (2^8) different combinations. |
| 8-bit Memory Modules - These DRAM modules have 8 separate data lines. 30-pin SIMMs are 8-bit memory modules. If you want to use them with a 32-bit chip such as a 386 or a 486... |
