It is a place in computing device where the operating system(OS), application programs and data in current use are kept so they can be quickly by the device's processor. RAM is much faster to read from and write to than other kinds of storage devices used in a computer such as hard disk(HDD), ,solid-state  drive(SSD) or optical drive. Data remains in RAM as long as the computer is running. When the computer is turned off, RAM loses its data. When the computer is turned on again, the OS and other files are once again loaded into RAM, usually from an HDD or SSD. Lets compare RAM to a person's short-term memory and a hard disk to a long-term memory. Short-term memory focuses on the work at hand, but can only keep so many fact in view at one time.

In such sense when two devices are connected via USB OTG cable then a communication link is established between these devices. The controlling device is called "Master or Host" while the other one(being controlled is called "Slave or Peripheral). What you can do with an OTG? With the help of an USB OTG cable a lot of tasks can be done just by the establishment of a communication between two devices which are working as host and peripheral with each other. Fo...
