Personal Computer (pc)
Any computer-delivered electronic system that allows the user to control, combine, and manipulate different types of media, such as text, sound, video, computer graphics, and animation. Interactive multimedia integrates computer, memory storage, digital (binary) data, telephone, television, and other information technologies. Their most common applications include training programs, video games, electronic encyclopaedias, and travel guides. Interactive multimedia shifts the user's role from observer to participant and is considered the next generation of electronic information systems.
A personal computer (PC) system with conventional magnetic-disk memory storage technically qualifies as a type of interactive multimedia. More advanced interactive systems have been in use since the development of the computer in the mid-20th century—as flight simulators in the aerospace industry, for example. The term was popularized in the early 1990s, however, to describe PCs that incorporate high-capacity optical (laser) memory devices and digital sound systems. The most common multimedia machine consists of a PC with a digital speaker unit and a CD-ROM drive, which optically retrieves data and instructions from a CD-ROM. Many systems also integrate a handheld tool that is used to communicate with the computer. Such systems permit users to read and rearrange sequences of text, animated images, and sound that are stored on high-capacity CD-ROMs. Systems with CD write-once read-many (WORM) units allow users to create and store sounds and images as well. Some PC-based multimedia devices integrate television and radio as well. Among the interactive multimedia systems under commercial development by the mid-1990s were cable television services with computer interfaces that enable viewers to interact with television programs; high-speed interactive audiovisual communications systems that rely on digital data from fibre-optic lines or digitized wireless transmissions; and virtual reality systems that create small-scale artificial sensory environments.

VIRUS
Computer viruses activate when the instructions—or executable code—that run programs are opened. Once a virus is active, it may replicate by various means and tries to infect the computer’s files or the operating system. For example, it may copy parts of itself to floppy disks, to the computer’s hard drive, into legitimate computer programs, or it may attach itself to e-mail messages and spread across computer networks by infecting other shared drives. Infection is much more frequent in PCs than in professional mainframe systems because programs on PCs are exchanged primarily by means of floppy disks, e-mail, or over unregulated computer networks.
Viruses operate, replicate, and deliver their payloads only when they are run. Therefore, if a computer is simply attached to an infected computer network or downloading an infected program, it will not necessarily become infected. Typically a computer user is not likely to knowingly run potentially harmful computer code. However, viruses often trick the computer's operating system or the computer user into running the viral program.
Some viruses have the ability to attach themselves to otherwise legitimate programs. This attachment may occur when the legitimate program is created, opened, or modified. When that program is run, so is the virus. Viruses can also reside on portions of the hard disk or floppy disk that load and run the operating system when the computer is started, and such viruses thereby are run automatically. In computer networks, some viruses hide in the software that allows the user to log on the system. With the widespread use of e-mail and the Internet, viruses can spread quickly. Viruses attached to e-mail messages can infect an entire local network in minutes.
