given in numbers A measure of how consistently a result is determined by repeated evaluation. How close a reading or measurement comes to the actual value of the quantity being measured. Number with decimal after the 1st digit‚ multiplied by 10 with an exponent. A ratio that allows you to convert from one unit of measurement to another. Measured digits that are known with certainty plus one estimated digit The smallest marking on the instrument.

If you are new to binary‚ we highly recommend reading our binary and hexadecimal conversions section to get a better understanding of what we’re doing in the below charts. if we were to break down the IP "166.70.10.23"‚ you would get the below value. In the below table‚ the first row is the IP address‚ the second row is the binary values‚ and the third row shows how the binary value equals

based on increments of ten and decimals‚ and it is used by the rest of the world. The metric system uses the same units for each type of measurement for uniformity. For instance‚ length is always measured in meters‚ mass is always grams‚ and volume is always cubic meter or liter. In the US customary system‚ length can be measured by inches‚ feet‚ yards‚ miles‚

understands‚ a sequence of 0s and 1s that the computer’s controls interprets as instructions‚ electrically. First-generation languages required the writing of long strings of binary numbers to represent such operations as “add‚” “subtract‚” “and compare.” Later improvements allowed octal‚ decimal‚ or hexadecimal representation of the binary strings. 2ND GENERATION (ASSEMBLY LANGUAGE): Because writing programs in machine language is impractical (it is tedious and error prone)‚ symbolic‚ or assembly‚

3.1 The hypothetical machine of figure 3.4 also has two I/O instructions: 0011 = Load AC from I/O 0111 = Store AC to I/O In these cases‚ the 12-bit address identifies a particular I/O device. Show the program execution (using the format of Figure 3.5) for the following program: 1. Load AC from device 5. 2. Add contents of memory location 940. 3. Store AC to device 6. Assume that the next value retrieved from device 5 is 3 and that location 940 contains a value of 2. [pic]

The Open Systems Interconnection (OSI) model (ISO/IEC 7498-1) is a conceptual model that characterizes and standardizes the internal functions of a communications system by partitioning it into abstraction layers. The model is a product of the Open Systems Interconnection project at theInternational Organization for Standardization (ISO). The model groups similar communication functions into one of seven logical layers. A layer serves the layer above it and is served by the layer below it. For example
