Glossary of terms

ActiveX

This Microsoft’s proprietary technology is used for creation of dynamic objects for Web pages. This technology provides many features, such as writing to disk or execution of commands at the client (i.e. on the host where the Web page is opened). This technology provides a wide range of features, such as saving to disk and running commands at the client (i.e. at the computer where the Web page is opened). Using ActiveX , virus and worms can for example modify telephone number of the dial-up.

ActiveX is supported only by Microsoft Internet Explorer in Microsoft Windows op- erating systems.

Cluster

A group of two or more workstations representing one virtual host (server). Re- quests to the virtual server are distributed among individual hosts in the cluster, in accordance with a deﬁned algorithm. Clusters empower performance and increase reliability (in case of dropout of one computer in the cluster, the virtual server keeps running).

Connections

Bidirectional communication channel between two hosts. See also TCP.

Default gateway

A network device or a host where so called default path is located (the path to the Internet). To the address of the default gateway such packets are sent that include destination addresses which do not belong to any network connected directly to the host and to any network which is recorded in the system routing table.

In the system routing table, the default gateway is shown as a path to the destina- tion network 0.0.0.0 with the subnet mask 0.0.0.0.

Note: Although in Windows the default gateway is conﬁgured in settings of the network interface, it is used for the entire operating system.

DHCP

DHCP (Dynamic Host Conﬁguration Protocol) Serves automatic IP conﬁguration of computers in the network. IP addresses are assigned from a scope. Besides IP addresses, other parameters can be associated with client hosts, such as the default gateway address, DNS server address, local domain name, etc.
