1. The Internet is a vast interconnection of computer networks that extends the globe. It is comprised of millions computers that connect and share massive volumes of information. .

The Internet contains many layers of information, with each layer dedicated to a different kind of documentation. These different layers are called 'protocols'. The most popular protocols are the World Wide Web, FTP, Telnet, instant messaging, and email.

2. A program or group of programs designed for end users. Application software can be divided into two general classes: systems software and applications software. Systems software consists of low-level programs that interact with the computer at a very basic level. This includes operating systems, compilers, and utilities for managing computer resources.

In contrast, applications software includes database programs, word processors, and spreadsheets. Figuratively speaking, applications software sits on top of systems software because it is unable to run without the operating system and system utilities.

Examples would be games, word processors (such as Microsoft Word), and media players.

The processor in a personal computer or embedded in small devices is often called a microprocessor.
