Storage Area Networks are typically used to provide access to data storage. These make sure that storage devices such as disks, tape drives etc. can be accessed by an operating system as system storage devices. Storage Area Networks are quite cheap and so are used both by large conglomerates and ... Read More

Low earth orbit (LEO) satellites systems orbit below 2000 km from the earth’s surface, i.e. below the lower Van Allen belt. They move at very high speeds and may not have any fixed space with respect to the earth. The following diagram depicts LEO satellites in their orbits. ... Read More

Medium earth orbit (MEO) satellites lie between the two Van Allen Belts. MEOs are also called Intermediate Circular Orbits (ICOs). The altitudes of these satellites range from 2, 000 km to 35, 000 km, i.e. above the low earth orbits and below the geosynchronous orbits. The orbital periods of MEOs ... Read More

VSATs (Very Small Aperture Terminals) is a two way, lost cost, ground micro station for transmitting data to and from communication satellites. A VSAT has a dish antenna with diameters between 75 cm to 1 m, which is very small in comparison with 10 m diameter of a standard GEO ... Read More

Geosynchronous Satellite and Geosynchronous Orbit (GSO) A geosynchronous satellite is a communication satellite that has an orbital period same as the period of rotation of the earth. Hence, it appears to be permanently in the same area of the sky at a particular time each day when viewed by an ... Read More

The Join () method in strings concatenates all the elements of a string array, using the specified separator between each element. In the below example we have a multi-line string and we have set the separator as “\n” − String.Join("\n", starray); The following is the complete example − ... Read More
