Glossary

• Bandwidth.
A term describing the capacity to transfer data. Greater bandwidth is needed to
sustain a higher transfer rate. Greater bandwidth can be achieved, for example, by
using a wider bus.
• Bus.
A pathway along which signals are sent, generally in two directions, for
communication of data.
• Cache.
A memory area of the processor. The processor can access data from its cache faster
than it can access data from system RAM or mass storage devices.
Many processors have a primary cache and a secondary cache. When searching for
information, the processor first refers to the primary cache. If it cannot find the
required information, it will then refer to the secondary cache.
• Contiguous memory.
A block of physical memory occupying a single, consecutive series of locations.
• DDR4 SDRAM.
Double data rate three synchronous dynamic random access memory. A type of RAM
used for image capture and processing.
See also RAM.
• DHCP.
Dynamic host configuration protocol. A DHCP server automatically assigns
IP addresses to clients who log onto a TCP/IP network. It eliminates the need to
manually assign and manage unique IP addresses for all of the machines on a
network.
