A bit is a . binary digit. , 0 or 1. . The . name (probably) comes from the b from binary and the t from digit and one of the . i's. .. A bit . can represent anything that has two states: true/false, yes/no, on/off. 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. . Organization and Architecture. Memory Organization. Storage/Memory Hierarchy. Memory Storage Characteristics. Location. Capacity. Unit of transfer. Access method.

Why It is Emerging?. magnetic and conventional optical data storage technologies, where individual bits are stored as distinct magnetic or optical changes on the . Term. Abbreviation. Approximate Memory Size. Kilobyte. KB or K. =1000 bytes (actual size is 1024 bytes). Megabyte. MB. =1 million bytes. Gigabyte. GB. =1 billion bytes. Terabyte. TB. =1 trillion bytes. l. Digital Signals. The amplitude of a digital signal varies between a logical “0” and logical “1”. . The information in the signal is encoded in the combination:. of the length of time that the signal is held at each logical state . 16.1 Introduction. Databases typically stored on magnetic disks. Accessed using physical database file structures. Storage hierarchy. Primary storage. CPU main memory, cache memory. Secondary storage. Analog Signals. Analog. signals : constantly changing values. Difficult to make precise. Digital. Digital. signals : only allowed to have specific values. Binary. Computers are digital systems with 2 possible states: . How can we relate to the terms Bits and Bytes?. What do I mean when I say:. “This . computer has a 64-bit processor with 4 Gigabytes of RAM and 200 Gigabytes of hard disk . space.”. The Bit.
