Network Terms "Z"

ZAP File

A text file that references a conventional setup program. The ZAP file can be distributed to network users using Active Directory-based Group Policy Objects (GPOs).

Zeroconf

Zero Configuration Networking (Zeroconf) is a standards-based initiative of an IETF working groups whose goals are to:

• Make current computer network administration easier by performing configuration tasks automatically without the need for network services such as DNS or DHCP

• Enable the creation and implementation of a new generation of network related products

• Accomplish all of this without disrupting the existing network infrastructure of large networks

With Zeroconf, you should be able to connect two computers and automatically have them be able to communicate. You should also be able to set up a small network (even a network with multiple subnets or connected to the Internet) by simply connecting devices and without performing any additional configuration tasks.

Zone

A portion of the DNS namespace made up of a single domain or of a domain and subdomains that are administered as a single, separate entity.

A particular name server is responsible for each zone. The name server stores all address mappings for the domain name space with the zone. It also answers client queries for those names.

Zone transfer

The process of replicating updates to the zone information among multiple DNS servers. Regular zone transfers are necessary because as computers and other devices are added to or removed from a network, host names and IP addresses change.
