I-Terms
SD card: A Secure Digital Card is an ultra small flash memory card designed to provide high-capacity memory in a small size. SD cards are used in many small portable devices such as digital video camcorders, digital cameras, handheld computers, audio players and mobile phones. In use since 1999, SD memory cards are now available in capacities between 16 Megabytes and 1 Gigabyte. An SD card typically measures 32 x 24 x 2.1 mm and weighs approximately 2grams.
MiniSD card: After the success of the SD card, the miniSD memory card was developed to meet the demands of the mobile phone market. The MiniSD card provides the same benefits as the SD card, but is smaller in size.
These cards are typically found in many newer mobile phones with features such as built-in digital cameras, downloading and games; basically mobile phones where miniSD can meet the requirements for increased data storage.
MiniSD cards are 21.5 x 20 x 1.4 mm and generally provide 16MB to 256MB of storage.
PMP: Short for Portable Music Player, PMP describes any digital portable music player which allows users to download or save digital music files (in MP3 format) from their computer to play on their PMP. Some examples of a PMP would be iPod, iRiver, Rio Karma, and the NOMAD to name a few.
JavaSpaces: This is a powerful Jini service from Sun Microsystems, which facilitates building distributed applications for the internet and intranets.
The JavaSpaces model involves persistent object exchange areas in which remote processes can coordinate their actions and exchange data.
It provides a necessary ubiquitous, cross-platform framework for distributed computing, emerging as a key technology in this expanding field.
DDR2-SDRAM: This is high-performance main memory. Over its predecessor, DDR-SDRAM, DDR2-SDRAM offers greater bandwidth and density in a smaller package along with a reduction in power consumption. In addition DDR2-SDRAM offers new features and functions that enable higher a clock rate and data rate operations of 400 MHz, 533 MHz, 667 MHz, and above. DDR2 transfers 64 bits of data twice every clock cycle. DDR2-SDRAM memory is not compatible with current DDR-SDRAM memory slots.
Regression testing: This is the selective retesting of a software system that has been modified to ensure that any bugs have been fixed and that no other previously working functions have failed as a result of the reparations and that newly added features have not created problems with previous versions of the software.
Also referred to as verification testing, regression testing is initiated after a programmer has attempted to fix a recognized problem or has added source code to a program that may have inadvertently introduced errors.
Downstream: A transmission from a server to an end user. A downstream transmission can be in the form of a signal being transmitted from a server to a workstation across a network, such as a LAN, or a signal being sent from a cable service provider to a customer.
A transmission from an end user to a server is referred to as upstream.
Accelerator board: Short for graphics accelerator, this is a type of expansion board that makes a computer faster by adding a faster CPU or FPU.
Most modern computers are designed to accept simpler upgrades. Built into the motherboard is a socket in which the CPU sits. It is usually possible simply to remove the CPU and replace it with a faster model.
This is particularly easy if the socket is a zero insertion force (ZIF) socket.
Abandonware: This is software that is no longer being sold or supported by its publisher.
Most abandonware is still considered illegal unless the publisher has re-released the software as freeware.
US copyright laws state that copyrights owned by corporations are valid for 75 years from the date the software was first published. So the current availability of a product is irrelevant to its copyrighted status.
