A modem that provides broadband Internet access in the range of 10 to 30 Mbps.
For DNS and WINS, a local information store of resource records for recently resolved names of remote hosts. Typically, the cache is built dynamically as the computer queries and resolves names; it helps optimize the time required to resolve queried names.
A file used by the Domain Name System (DNS) server to preload its names cache when service is started. Also known as the root hints file because resource records stored in this file are used by the DNS service to help locate root servers that provide referral to authoritative servers for remote names. For Windows DNS servers, the cache file is named Cache.dns and is located in the %SystemRoot%\System32\Dns folder.
The process of storing recently-used data values in a special pool in memory where they are temporarily held for quicker subsequent accesses. For DNS, the ability of DNS servers to store information about the domain namespace learned during the processing and resolution of name queries. In Windows 2000, caching is also available through the DNS client service (resolver) as a way for DNS clients to keep a cache of name information learned during recent queries.
For Windows 2000, a client-side Domain Name System (DNS) name resolution service that performs caching of recently learned DNS domain name information. The caching resolver service provides system-wide access to DNS-aware programs for resource records obtained from DNS servers during the processing of name queries. Data placed in the cache is used for a limited period of time and aged according to the active Time To Live (TTL) value. You can set the TTL either individually for each resource record (RR) or default to the minimum TTL set in the start of authority RR for the zone.
The number that a RAS server uses to call back a user. This number can be preset by the administrator or specified by the user at the time of each call, depending on how the administrator configures the users callback status. The callback number should be the number of the phone line to which the users modem is connected.
