Answer :
Explanation :
The smallest unit of data storage in a computer is called Bit (Binary Digit). Half a byte (four bits) is called a Nibble. 1 bit (binary digit) = the value of 0 or 1 8 bits = 1 byte 1024 bytes = 1 kilobyte 1024 kilobytes = 1 megabyte 1024 megabytes = 1 gigabyte 1024 gigabytes = 1 terabyte 1024 terabytes = 1 petabyte Hence, Computer storage units smallest to largest i.e, in ascending order is 1 bit < 1 byte < 1 KB < 1 MB < 1 GB < 1TB < 1 PB.

Answer : 1. "49.6%"
Explanation :
Answer: A) 49.6% Explanation: As these three strategies P, Q and R are independent so these will cut cost one after the other.If initial cost is Rs 100, then20% cost is cut after initializing strategy P, then cost will remain 80% = 80further 30% cost is cut after strategy Q, then cost will remain 70% of 80 = 56further 10% cost is cut after strategy R, then cost will remain 90% of 56 = 50.4 Thus final cost remains 50.4 % of the original cost. Hence net saving is 100 - 50.4 = 49.6 %.
