compare

Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field:

To compare is to bring two or more things together (physically or in contemplation) and to examine them systematically, identifying similarities and differences among them. Comparison has a different meaning within each framework of study. Any exploration of the similarities or differences of two or more units is a comparison. In the most limited sense, it consists of comparing two units isolated from each other.
To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and in the arts.

    Radiator’s valve hammering

    As you can see my heating system upgrade saga continues. Current problems is that valve on one of my rads (in the bathroom) is making what can be best described as ‘hammering’ sounds (10-15 sec apart) when it heats up and produces more of a loud ‘crackling’ sounds when cooling down. As far as I...

    Boosted Domestic Cold Water

    [27-10, 08:26] Ringbolt I have rubbish water pressure and a combi which means that I can only have one shower or tap on at a time. Is there any reason why I cannot put in say 100l cold water tank and 2bar pump before the combi to give constant boosted pressure to the system?
