Data warehousing emphasizes the capture of data from diverse sources for useful analysis and access.
Photocopies or hand-drawn materials can be sent via a fax modem only if an optical scanner is connected. The gateway translates all protocols and applications in both directions to facilitate the interconnection between the networks. Smaller models are also called notebook computers. A laserdisk, also called a videodisk, can hold up to 50,000 still pictures or up to 2 hours of video and audio. When connected to a computer, a laserdisk player becomes interactive.
