Basic Hardware Units of a Computer. Bits and Bit Patterns. Bit:. Binary Digit (0 or 1). Bit Patterns are used to represent information.. Numbers. Text characters. Images. Sound. And others. Boolean Operations. Digital . Data Communications Techniques. Digital Data Communications Techniques. A conversation forms a two-way communication link; there is a measure of symmetry between the two parties, and messages pass to and fro. There is a continual stimulus-response, cyclic action; remarks call up other remarks, and the behavior of the two individuals becomes concerted, co-operative, and directed toward some goal. This is true communication. . 1. Readings. Chapter . 10. 2. Long-term Information Storage. Three essential requirements:. Must store large amounts of data.
