Seawater or salt water is water from a sea or ocean.

On average, seawater in the world's oceans has a salinity of approximately 3.5% or 35 parts per thousand. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts dissolved in it.

Hence, The average salinity of seawater is 3.5%.

Long term scheduler determines which programs are admitted to the system for processing. It controls the degree of multiprogramming. Once admitted, a job becomes a process.

Medium term scheduling is part of the swapping function. This relates to processes that are in a blocked or suspended state. They are swapped out of real-memory until they are ready to execute. The swapping-in decision is based on memory-management criteria.

Short term scheduler, also know as a dispatcher executes most frequently, and makes the finest-grained decision of which process should execute next. This scheduler is invoked whenever an event occurs. It may lead to interruption of one process by preemption.

a.) Quality Assurance

Quality assurance is an activity that establishes and evaluates the processes that produce products. Quality assurance would measure processes to identify weaknesses and then correct them to continually improve the process: Eg. Code review.

b.) Quality Control

Quality control is a process in which the product's quality is compared with standards and corrective actions taken if required. Quality control activities focus on identifying defects in the actual products produced. Eg. Testing.

c.) Test Case

A test case is a unit level document describing the inputs, steps of execution and the expected result of each test condition for every requirement from the BRD. Testers determine whether the application is working correctly or not based on the test case that is being executed. A test case is marked as "Pass" if the application works as expected and is marked as "Fail" if otherwise. Test cases also aide in generating test status metrics.

d.) Test Condition

Test condition is the condition on which the test execution evaluates to pass or fail. Eg of a test condition: Set Password field should accept a mix of Alphanumeric and Special characters on mandatory basis and throw error message otherwise.

e.) Test Script

Test script is the set of instructions performed on the application to verify its functions.

f.) Test Data

Test data is the input data used to test a particular functionality. Eg: Username and password to test a login screen.

g.) Test Bed

Test bed is the environment on which the testing is done and includes the software and hardware set up that is required for testing the application.

A metalloid is any chemical element which has properties in between those of metals and nonmetals, or that has a mixture of them.

The six commonly recognised metalloids are

boron,

silicon,

germanium,

arsenic,

antimony, and

tellurium.

There are many reasons why a constitution is needed. One of the primary purposes is to define and limit power of the government.

It gives the structures for the functioning of the country such as courts and parliament and limits the power.

e.g. to imprison without trial for the government.
