What Download is
To transfer a file or files from one computer to another, for example, from a server to your desktop computer. Download is the opposite of upload. There are a few methods of downloading on the Internet: HTTP, FTP and e-mail attachments are the most common. When you "load" a Web page into your browser, you are essentially "downloading" the page from the server it is hosted on. One of the most resourceful functions of the Internet is that you can download almost any type of computer file or program. Many of these files are shareware, which means you can try them before you buy them. Want to try downloading something?
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.
