MBps or MegaBytes per second is a unit of data transfer rate to and fro a computer storage device. One megabyte is 2 to the 20th power bytes which is equivalent to 1,048,567 bytes in decimal notation. Computer data interfaces are often measured in MBps. It is often confused with Mbps or Megabits per second.


Mbps which stands for Megabits per second is a unit of information transfer rate used to measure data transfer speeds of high bandwidth connections like Ethernet and cable modems.

Propagation is the process whereby the nameservers across the world’s Internet servers update their records for a particular domain. For example, say if you move your domain from one host to another, it will generally take around 24 hours or so for the new address to broadcast everywhere. During that 24 hour period, the traffic is less at the old location and high at the new one.

Parking (Domain Name)

Parking (Domain Name) is the method by which someone can select a domain name, and "park" it by registering the domain name under someone’s name servers. One does not have to give the domain name servers of their hosting company. The parked domain names are registered with the InterNIC. However, the parking domain names can’t be used for website or e-commerce services.

This facility is useful when you have a domain name which you do not want to use immediately. What you can do is reserve the name for future use.
