10+ Tismo Technology Solutions Interview Questions and Answers

A counter can be created using D flip-flops by connecting the output of one flip-flop to the input of the next.

• Connect the Q output of one D flip-flop to the D input of the next flip-flop

• Use clock signal to trigger the flip-flops and increment the count

• Use additional logic gates if needed for specific counter functionality

Interrupts are signals sent to the CPU to temporarily suspend the current program and execute a specific task.

• Interrupts allow the CPU to handle external events without constantly checking for them.

• There are different types of interrupts such as hardware interrupts and software interrupts.

• Examples of interrupts include keyboard input, timer expiration, and hardware errors.

Controllers are devices that manage the operation of other devices or systems.

• Controllers receive input, process it, and send output signals to control the operation of other devices.

• Examples of controllers include microcontrollers, PLCs (Programmable Logic Controllers), and PID controllers.

• Controllers can be used in various applications such as industrial automation, robotics, and consumer electronics.

Balancing education and extracurricular activities is crucial for holistic development.

• Prioritize tasks and create a schedule to allocate time for both education and activities.

• Set realistic goals and manage time efficiently to avoid burnout.

• Seek support from teachers, parents, or mentors to maintain a healthy balance.

• Use extracurricular activities to enhance skills that can complement academic learning.

• Learn to delegate tasks and practice effective time management techniques...read more

Test case for pen and leave letter form

• Verify pen writes smoothly on paper

• Check if pen ink is not leaking

• Ensure all fields in leave letter form are editable

• Submit form and verify successful submission message

To find the 2nd smallest element in an array in C programming, we can sort the array and then access the element at index 1.

• Sort the array in ascending order using a sorting algorithm like bubble sort or quicksort.

• Access the element at index 1 to get the 2nd smallest element.

• Example: int arr[] = {5, 2, 8, 1, 3}; After sorting: {1, 2, 3, 5, 8}. 2nd smallest element is arr[1] = 2.

A program to check if a given number is a power of 7.

• Use a loop to continuously divide the number by 7 until it becomes 1 or not divisible anymore.

• If the final result is 1, then the number is a power of 7.

• If the final result is not 1, then the number is not a power of 7.
