These websites reside on computers called (F) __________, which store files accessible to users globally.

For example, an address might look like 106.29.242.17. However, this IPv4 system provides only (M) __________ billion possible addresses, which proved inadequate. Consequently, (N) __________ was developed, offering a (O) __________-bits address space using hexadecimal format separated by colons.
For user convenience, the Internet employs (P) __________ addressing, which converts numerical IP addresses into readable names. A program called (Q) __________ software, running on domain name servers, coordinates this translation. Domain names follow a hierarchical structure read from right to left. For instance, in "knust.edu.gh," the suffix "gh" indicates (R) __________, while "edu" signifies an (S) __________ institution.
To locate specific files on web servers, browsers utilize (T) __________, which combine the transfer protocol (commonly HTTP or HTTPS), domain name, pathname, and filename into a complete address. The secure version, HTTPS, encrypts data exchanges between web browsers and servers, protecting against eavesdroppers and man-in-the-middle attacks—a critical feature indicated by a lock icon in the browser's address bar.
