What type of interface circuit is required between the MPU data lines and a 7 segment display?
a latch
What are handshaking signals?
These are dedicated lines used to coordinate data transfer. They are used to signal ready/not ready, or to acknowledge or request. This back and forth handshaking is needed in async comms to avoid sending data until the receiver is ready for it. The MPU and peripherals operate at different speeds, the MPU being faster than the peripherals(like printers and data converters). To avoid overlapping of data during data input (by preventing MPU reading same data twice before i/p peripheral writes next data) or data output (by preventing MPU from writing over the data before o/p device has had a chance to accept it), handshake signals are used between MPU & the peripherals. These signals are generally provided by programmable devices.
Can you give the explanation for various operations in a queue implementation using arrays?
The following are operations performed by queue in data structuresEnqueue (Add operation)Dequeue (Remove operation)Initialize
What is taper turning on lathe machine?
An operation performed on a lathe that feeds a tool at an angle to the length of the workpiece in order to create a conical shape.
What is the need of deque?
A double ended queue (or deque ) is a queue where insertion and deletion can be performed at both end that is front pointer can be used for insertion (apart from its usual operation i.e. deletion) and rear pointer can be used for deletion (apart from its usual operation i.e. insertion). So when we need to insert or delete at both end we need deque.
