Online Transaction Processing(OLTP)

2:50 PM 0 Comment

OLTP (online transaction processing) is a class of program that facilitates and manages transaction-oriented applications, typically for data entry and retrieval transactions in a number of industries, including banking, airlines, mailorder, supermarkets, and manufacturers.


Today's online transaction processing increasingly requires support for transactions that span a network and may include more than one company. For this reason, new OLTP software uses client/server processing and brokering software that allows transactions to run on different computer platforms in a network

 

Real-Time Operating System (RTOS)

12:14 PM 0 Comment

A real-time operating system (RTOS) is an operating system that guarantees a certain capability within a specified time constraint.

In general, real-time operating systems are said to require:

Multitasking
Process threads that can be prioritized
A sufficient number of interrupt levels

Real-time operating systems are often required in small embedded operating systems that are packaged as part of microdevices. A real-time operating system is usually larger than just the kernel.

Single Point of Failure (SPOF)

12:01 PM 0 Comment

A single point of failure (SPOF) is a potential risk posed by a flaw in the design, implementation or configuration of a circuit or system in which one fault or malfunction causes an entire system to stop operating.

In a data center or other information technology (IT) environment, a single point of failure can compromise the availability of workloads – or the entire data center – depending on the location and interdependencies involved in the failure.

Power usage effectiveness

2:44 PM 0 Comment

Power usage effectiveness (PUE) is a measure of how efficiently a computer data center uses its power; specifically, how much of the power is actually used by the computing equipment (in contrast to cooling and other overhead).
PUE= Total facility power /IT equipment power

PUE is the ratio of total amount of power used by a computer data center facility to the power delivered to computing equipment.

PUE is the inverse of data center infrastructure efficiency (DCiE). An ideal PUE is 1.0.
