A local area network (LAN) is a privately own computer network that connects computers and other information processing device within a limited area (few kilometers) such as a home, school/classroom, building, manufacturing plant, computer laboratory, or office building using network media. In many organizations, it has become commonplace for LANs to provide telecommunications network capabilities that link end users in departments, offices, and other workgroups. Coaxial cable, ordinary wiring, and even wireless radio and infrared systems, to interconnect microcomputer workstations and computer peripherals are some examples of LANs that are used with telecommunications media.

In its modern sense, computer hacking means gaining unauthorized access to computer and network resources often, but not always, with malicious intent. Hackers break into computer systems by exploiting security vulnerabilities, such as poor configuration of Web servers, disabled security controls or poorly chosen or default passwords.

Domain names are used to identify one or more IP addresses. For example, the domain name microsoft.com represents about a dozen IP addresses. Domain names are used in URLs to identify particular Web pages. For example, in the URL http://www.pcwebopediaindex.html, the domain name is pcwebopedia.com.
Every domain name has a suffix that indicates which top level domain (TLD) it belongs to. There are only a limited number of such domains. For example:
•gov - Government agencies
•edu - Educational institutions
•org - Organizations (nonprofit)
•mil - Military
•com - commercial business
•net - Network organizations
•ca - Canada
