Explain Idioms With Examples. For example, his words were taken down, and though he tried to explain them away, he was sent to the tower (thomas. For example, if you say someone has “cold feet,” it doesn’t mean their toes are actually cold.

“an idiom is a group of words established by usage as having a meaning not deducible from those of the individual words (e.g.over the moon, see the light).”idioms can reduce your speaking time and boost up your credibility of english speaking. Definition of explain in the idioms dictionary. Accomplishing two different tasks in the same undertaking.

Explain Swapping In Operating System. Paging is a storage mechanism that allows os to retrieve processes from the secondary storage into the main memory in the form of pages. Swapping is a mechanism in which a process can be swapped temporarily out of main memory (or move) to secondary storage (disk) and make that memory available to other processes.

Swapping allows multiple programs to run parallelly in the operating system. The biggest advantage of paging is that it is easy to use memory management algorithm. Similarly when ram is free, then we again swap in the programs from hard disk to ram.

Explain Joins In Sql. Joins are the types of a single concept, which allows the joining of two or more tables using a defined syntax in sql programming. So, we’ll be using full join throughout our sql query:

After executing the query, it produces the following table. This is done by matching keys between tables. Inner join (also known as a ‘simple’ join ).

Explain Continental Drift Theory. The theory of continental drift proposes that the continents are drifting away from each other because they are located on tectonic plates,. In the early 20th century, wegener published a paper explaining his theory that the continental landmasses were “drifting” across the earth, sometimes plowing through oceans and into each other.

Wegener found resistance to his theory because his first proposals estimated. Continental drift was a revolutionary theory explaining that continents shift position on earth's surface. The theory of continental drift was proposed at the beginning of the last century by german scientist alfred wegener.

Explain The Third Law Of Thermodynamics. Explain what measurements are needed to evaluate the absolute standard entropy of a gas phase pure substance at 298 k. The third law of thermodynamics states that when the temperature of a system approaches absolute zero, the entropy of that system approaches a constant value.

At zero temperature, the system must be in a state with the minimum thermal energy. The entropy of a perfect crystal at absolute zero is exactly equal to zero. Explain what measurements are needed to evaluate the absolute standard entropy of a gas phase pure substance at 298 k.
