What Web designer is
The aesthetic and navigational architect of a Web site, the designer is the person responsible for how the site looks and feels. He or she is the one who takes the heat if the graphics are fuzzy, the links are too light, or something is hard to find on a Web page. Usually this person is trained in the creative side of image development; however, an extensive knowledge of Web-based programming and information architecture is considered fundamental to being a successful Web designer. (That and good client-relationship skills are a must.)
The meaning of DHCP
Dynamic Host Configuration Protocol. A protocol that provides a means to allocate IP address dynamically to computers on a LAN. It eliminates the need to assign permanent IP addresses manually. DHCP software runs on servers and can be found in network devices (such as routers) that allow multiple users to access the Internet. Microsoft introduced DHCP on their Windows NT server in 1994. Newer DHCP servers will dynamically update DNS servers after assigning the addresses.
