A Transaction Processing System (TPS) is an information system that collects, stores, modifies, and retrieves the data transactions of an enterprise. Transaction processing systems also attempt to provide predictable response times to requests, although this is not as critical as real-time systems.
Response time is the amount of time a pixel in a display takes to change. It is measured in milliseconds (ms). Lower numbers mean faster transitions and therefore fewer visible image artifacts. Display monitors with long response times would create display motion blur around moving objects, making them unacceptable for rapidly moving images.
PRISM is a code name for a program under which the United States National Security Agency (NSA) collects internet communications from various U.S. internet companies. [ 1][ 2][ 3] The program is also known by the SIGAD US-984XN. [ 4][ 5] PRISM collects stored internet communications based on demands made to internet companies such as Google LLC ...
Nordstrom, Inc. ( / ˈnɔːrdstrəm /) is an American luxury department store chain headquartered in Seattle, Washington, and founded by John W. Nordstrom and Carl F. Wallin in 1901. The original Wallin & Nordstrom store operated exclusively as a shoe store, and a second Nordstrom's shoe store opened in 1923.
Security information and event management ( SIEM) is a field within the field of computer security, where software products and services combine security information management (SIM) and security event management (SEM). [ 1][ 2] SIEM is typically the core component of any security operations center (SOC), which is the centralized response team ...
Measurement and signature intelligence ( MASINT) is a technical branch of intelligence gathering, which serves to detect, track, identify or describe the distinctive characteristics (signatures) of fixed or dynamic target sources. This often includes radar intelligence, acoustic intelligence, nuclear intelligence, and chemical and biological ...
Lidar ( / ˈlaɪdɑːr /, also LIDAR, LiDAR or LADAR, an acronym of "light detection and ranging" [ 1] or "laser imaging, detection, and ranging" [ 2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
Control systems. In control theory the impulse response is the response of a system to a Dirac delta input. This proves useful in the analysis of dynamic systems; the Laplace transform of the delta function is 1, so the impulse response is equivalent to the inverse Laplace transform of the system's transfer function .
