31. What is the use of // operator in Python? Ans : Python provides // operator to perform floor division of a number by another. The result of // operator is a whole number (without decimal part) quotient that we get by dividing left number with right number. It can also be used floordiv(a,b). E.g. 10// 4 […]

21. What is the significance of functions that start and end with _ symbol in Python? Ans : Python provides many built-in functions that are surrounded by _ symbol at the start and end of the function name. As per Python documentation, double _ symbol is used for reserved names of functions. These are also known as

11. What is the difference between List and Dictionary data types in Python? Ans : Main differences between List and Dictionary data types in Python are as follows: Syntax: In a List we store objects in a sequence. In a Dictionary we store objects in key-value pairs. Reference: In List we access objects by index number. It starts

A bootloader is a small program that starts when a device is powered on, facilitating the launch of the operating system. Its key functions include: 1. Hardware Initialization :Prepares the system components for operation.2. Loading OS Kernel:Loads the core of the operating system into memory.3. Secure Boot:Ensures the integrity of the boot process to prevent

Generation of A State Diagram from A Timing Chart A common method in describing digital systems uses a timing chart. This chart indicates the operations must take place during particular time slots in order for the system to function properly. These operations are initiated by control signals and the timing chart indicates when each control
UNIT IV ASYNCHRONOUS SEQUENTIAL LOGIC (Pending – Pre MCQ) THEORY : An asynchronous (ripple) counter is a single JK-type flip-flop, with its J (data) input fed from its own inverted output. This circuit can store one bit, and hence can count from zero to one before it overflows (starts over from 0). This counter will

Simulation and Synthesis in VLSI In the design flow of digital circuits, simulation and synthesis are two crucial steps. Simulation: A design must be checked to ensure that it is functionally correct, after it has been specified and entered. Simulation is the process of running a design through a software simulator to
