how to prepare for an interview of Operating System

January 09, 2021

 how to prepare for an interview Operating System 

In this article, we will be discussing the questions and answers about the operating system, which habitually asked in interviews.

What is it Operating System?

The operating system is a software program that facilitates computer hardware to interconnect and operates with the computer software. It is the most prime part of a computer system. Without an operating system, a computer is just like a box.

What is the leading purpose of an Operating System?

There are two leading purposes of an operating system.

1.    It maps out to make sure that a computer system executes well by managing is computational activities.

2.    It comes up with an environment for the development and execution of programs.

Define Deadlock?

Deadlock is a comprehensive circumstance where two processes are hanging fire for each other to total so that they can tackle. But this circumstance causes droop for both of them.

What is Kernel?

The kernel is a computer program at the nucleus of a computer's operating system that has complete command over everything in the system. It is the segment of the operating system code that is always occupant in memory and prerequisite interlinkage between hardware and software constituents.

What do you mean by SMP?

SMP refers to symmetric multi-processing. It is the most typical kind of multi-processor systems. In this system, each computer runs an equivalent copy of the operating system, and these copies converse with one another as desired.

What is the Real-Time System?

When rigid-time demands have emplaced on the operations of the processor, then the real-time system is used. It contains well-defined and fixed time constraints.

What is Piping?

It is the procedure of using the output of one plan as an input to another. For example, in its place of sending the catalog of a folder or constrains to the key screen, it can be piped and sent to a file to create a hard copy.

Define the Bankers' Algorithm?

Banker’s algorithm is one shape of deadlock eluding in a system. It gets its forename from a banking system wherein the bank never allocates in circulation cash in such a move that it can no longer gratify the needs of all of its customers.

Define Virtual Memory?

Virtual memory is a beneficial memory management method that enables the process to carry out outside of memory. This method is exceptionally used when an executing plan cannot fit in the corporeal memory.

TIPS FOR ONLINE STUDY



Here are some go-to study tips for learning. In this blog, we gave you some tips about the study. When studying this blog helps you a lot.
NO 1: SET DAILY GOALS FOR STUDYING:
Ask yourself what you hope to accomplish in your study each day. Setting a clear goal can help you stay motivated and beat procrastination. The target should be specific and easy to measure, such as I will watch all the videos of the second semester and complete the first programming assignment. And don't forget to make progress towards your goal.
NO 2: CREATE A DEDICATED STUDY PLACE:
It's easier to revive erudition if you're in the same place where you first learned it, so having a dedicated space at home to take study can make your learning more effective. Remove any distractions from the room and also separate from your bed or sofa. A clear distinction between where you study and where you take breaks can help you focus.
NO 3: RECORD TIME TO STUDY ON YOUR SCHEDULE:
Open your schedule and choose an assumed reliable time that you can commit to watching lectures and completing assignments. They help assure that your study won't become the last thing on your to-do list.
NO 4: KEEP YOURSELF LIABLE:
Tell your friend about the courses you're taking post hits to your social media accounts, or blog about your homework assignments. Having an association and support network of friends and family to encourage you on makes a difference.
NO 5: ACTIVELY TAKE NOTES:
Taking notes can improve vital thinking boost knowledge to enlarge your attention span. It's a strategy to internalize knowledge when you're learning online or in the classroom. So grab a notebook or find a digital app that works best for you and start synthesizing key points.
NO 6: JOIN THE DISCUSSION:
Course discussion forums are a great place to ask questions about assignments, discuss topics, share resources, and make friends. Our research shows that apprentices who engage in the discussion.
NO 7: DO ONE THING AT A TIME:
Multitasking is less fruitful than focusing on a particular task at a time. Research determined that "People who regularly bombarded with several streams of electronic information cannot pay attention recall information or switch from one job to another as well as those who complete one task at a time." stay focused on one task at a time. You will learn more information.
NO 8:  TAKE BREAKS:
Resting your mind after learning is crucial to high achievement. If you find yourself working on a challenging problem without much process for an hour, take a pause. Walking outward, taking a shower stall, or talking with a friend can re-energize you and even give you new thoughts on how to begin that project.

Data Science Interview Questions

July 10, 2020

 Mostly Asked Questions In Data Science Interview:
The following ten problems mostly asked in a data science interview. We recommend you when you go for a data science interview. First of all, you must update these ten questions.
No 1: four characters a, b, c, d, need to pass a bridge at right, and they have only one torch. The bridge is too risky to cross. Without a torchlight and is strong enough to support a maximum of two people at a time. They take 1, 2, 5, and 8 minutes sequentially. What is the shortest time required for all four of them to cross the bridge?
No 2: there are 100 black shoes and 100 white shoes mixed up in a drawer? If you have to pick shoes blindly from the drawer, how many shoes do you want to take out to be sure that you have a matching pair of shoes?
No 3: there are nine balls that weight the same except for one, which is hefty than the others. What is the maximum number of weighing should? Do you perform to find the ball with a higher weight?
No 4: there are 100 doors are all closed. A person walks through these 100 doors 100 times. Each time he toggles some of the doors, for example, closes if open and open if it is closed. Firstly, he will toggle all the doors secondly will toggle every second door thirdly will toggle every third door. So after the 100th walk, which entries will be open and which we are closed?
No 5: there are two sand times which show 4 minutes and 7 minutes individually. What would be the best approach to get a time of 9 minutes using both the sand timers, at one time or one after another, or in any other combination?
No 6: there are four men a, b, c, and d buried up to their necks in the ground in a straight line? There is an opaque wall between a & b. They cannot move and can only look forward such that a and b can only see their respective sides of the walls and c can see b, and d can see b and c. They are all aware that each of them is wearing a hat, and that two of them are wearing a black hat while the other two are wearing white hats. They don’t know what color they are wearing. To avoid being executed, one of them must call out to the executioner the color of their hat. If they get it wrong, everyone will be sort. After 60 seconds, one of them calls out. Which one of them calls out? How can sure he knows the color of his hat? There's no outside influence and no other way of communicating.
No 7: there are two ropes and a lighter. The string takes precisely 60 minutes to burn completely. But rope doesn't burn at a constant rate, so you do not know that half the rope burn in 30 minutes. For instance, if one end of the string is it, it may take 55 minutes to the first half of it, and 55 minutes to burn the second half. How can you measure exactly 45 minutes by burning the ropes?
No 8: there are two jars with 50 yellow marbles and 50 orange marbles. You place all the marbles in jars in such a way that if you blindly pick one marble out of that jar.  You can arrange the marbles however you like, but they must be in the air.
No 9: how many times a day do the minute and hour hands of a clock overlap?
No 10: at a party, everyone shook hands with everybody else. There were 66 handshakes. How many people were at the party?
