Select the correct differences between char and varchar data types? i. varchar is non unicode and char is unicode character data type ii. char is ‘n’ bytes whereas varchar is actual length in bytes of data entered in terms of storage size iii. varchar is variable in length and char is the fixed length string iv. For varchar, if a string is less than the maximum length then it is stored in verbatim without any extra characters while for char if a string is less than the set length it is padded with extra characters to equalize its length to given length

Which of the following statements regarding interface circuit are correct? 1. Electrical buffering is needed when the peripheral operates at a different voltage or current to that on the microprocessor bus system or there are different ground references. 2. Timing control is needed when the data transfer rates of the peripheral and the microprocessor are different. 3. Changing the number of lines is needed when the codes used by the peripherals differ from those used by the microprocessor.
The peripheral speed is the armature peripheral speed in the stationary field coils.
The process of transferring data intended for a peripheral device into a disk (or intermediate store) so that it can be transferred to peripheral at a more convenient time or in bulk, is known as
