Errata
p. 42. The number listed as maximum for a 64-bit CPU is missing the first digit. It should be:
18,446,744,073,709,551,616.
p. 365 Answer 1 should be C, not D. The descriptive text is correct.
p. 420 (insert entry) GiB (gibibyte) See IEC binary prefixes.
p. 422 (insert entry) horizontal scaling In terms of database performance, the capability of adding additional servers (i.e., compute nodes) to a database system to handle increased demand; requires (database) software written to accommodate both more than one server and on-the-fly addition (and subtraction) of servers.
p. 423 (insert entry) IEC binary prefixes Beginning part of a unit of measurement representing powers of 2; part of the International Electrotechnical Commission (IEC) standards. Standard IEC binary prefixes include 210 (kibi, or Ki), 220 (mebi, or Mi), and 230 (gibi, or Gi); i.e., 1024, 1,048,576, and 1,073,741,824, respectively. Used correctly to refer to units of binary storage (e.g., a thumb drive stores 32 GiB of data—32 gibibytes of data). See also, SI prefixes.
p. 425 (insert entry) latency Amount of delay before a device may respond to a request; most commonly used in reference to RAM.
p. 438 (insert entry) SI prefixes Beginning part of a unit of measurement representing powers of 10; part of the International System of Units (SI). Standard SI prefixes include 103 (kilo, or K), 106 (mega, or M), and 109 (giga, or G); i.e., 1000, 1,000,000, and 1,000,000,000, respectively. Used correctly to refer to units of electrical frequency (e.g., a CPU runs at 4 GHz—four gigahertz, or 4 billion cycles per second). Often used incorrectly to refer to units of binary storage (e.g., a thumb drive stores 32 GB of data—32 gigabytes of data). See also, IEC binary prefixes.
p. 441 (insert entry) throughput Rate of successful message delivery over a communication channel, such as a wired or wireless network; often called “network speed” or “bandwidth,” though those terms have different connotations.
