Premium Data transmission Computer networking Transmission
flow of data is unidirectional. i.e. one can transmit and other can receive. E.g. keyboard and monitor. 3. What is half-duplex? Ans: It is the mode of communication between two devices in which flow of data is bidirectional but not at the same time. ie each station can transmit and receive but not at the same time. E.g walkie-talkies are half-duplex system. 4. What is full duplex? Ans: It is the mode of communication between two devices in which flow of data is bidirectional and it occurs simultaneously

TIG welding T ungsten inert gas (TIG) welding is a high quality low deposition rate welding process. It uses an arc struck between a nonconsumable tungsten electrode and the work to fuse the base material and thereby form a welded joint. The TIG welding process may be used on thin sheet material without the addition of a filler metal (autogenous TIG welding). Alternatively‚ when working on thicker sheet or when joining dissimilar materials‚ a separate wire filler metal is added
