What is a Monitor?

-
The display screen of a computer and the case in which it is contained is called a monitor. They come in a variety of screen sizes. A typical monitor has a screen that measures 14 inches diagonally, but larger screens are also available. Monochrome monitors are able to display only one colour against a background, while colour monitors are capable of displaying many colours. The more bits a monitor uses to represent each pixel, the greater the number of colours the monitor can display. Analog monitors accept a continuous or analog signal that allows them to display an infinite variety of colours, while digital monitors can display only a fixed number of colours. Some monitors can accept either analog or digital signals. The video adapter sends signals to the monitor and determines, within the limits imposed by the monitor's structure, what the display will look like. The video standard supported by a video adapter determines the resolution and colours that a monitor can display. It is also called the video display terminal. There are also fixed-frequency monitor, multifrequency monitor, multiscanning monitor, etc.

Because these men also traded with debts, they could be called the first  brokers . A common misbelief is that, in late 13th-century  Bruges , commodity traders gathered inside the house of a man called  Van der Beurze , and in 1409 they became the "Brugse Beurse", institutionalizing what had been, until then, an informal meeting, but actually, the family Van der Beurze had a building in  Antwerp  where those gatherings occurred;  the Van der Beurze had Antwerp, as most of the merchants of that period, as their primary place for trading. The idea quickly spread around  Flanders

How Big is the Earth?

The distance around the Earth, that is, it's circumference around the equator is 40,091 kilometres. The diameter (the distance across the centre of the Earth ) at the equator is 12,756 kilometres. The Earth is slightly smaller when measured between the poles (12,713 kilometres), so it is not an exact sphere. If the Earth is weighted on a weighing machine, it would be nearly 6x10 tonnes.
