Principles of Computer System Design: An Introduction| How it can help to crack interviews?

by Nathan William Nathan William work at myassignmenthelp.com

Most students struggle to write assignments on computer system design. As a result, they opt for assignment help to submit the papers on time.

Have you ever wondered that if writing an assignment is difficult for you, how will you succeed in cracking a job interview?

In this article, we have highlighted one interview question that you can only answer if you read the ‘Principles of Computer System Design: An Introduction’.

Check it out below:

How will you design Facebook or Twitter, a social media service which has millions of users?

By asking this question, the interviewer wants to know how would you design efficient storage for the posts, social graphs like who befriended whom or who followed whom and the newsfeed generation.

To answer such questions you need to delve deeply into API design and backend structure. You need to talk about how the users will interact with the middle-tier endpoints, how the logging would function, and how you will design the backend to ensure uptime and a whole lot of things. 

Tackling the problem -

If you are addressing this type of question for the first time, then it is advised to formulate a set of criteria for yourself. Keep the following things in mind:

•    The goal of the system

•    The users of the system

•    The scale you are about to work with

•    The ways to handle the versioning

 

Use these criteria to paint a picture in your mind that will guide you through the decision making process.  For instance, when your interviewer asked you about the system design of Facebook or Twitter, think about the following things:

•    What does Facebook or Twitter do?

•    How can you sell it as a service?

•    How many users will use it?

•    How can I build a backend so that users can store their messages and pictures on their profile?

It can be quite easy to get academic writing help in case you are doing your system design assignments. But, while you appear for interviews, you need to be thorough with the concept of computer system designs. If you read the book ‘Principles of Computer System Design: An Introduction’, you can easily answer the above question.

 

Here’s how you can nail an interview:

‘Principles of Computer System Design: An Introduction’ provides an introduction to computer system designs. By reading this, you can build a solid foundation about the mechanisms that underlie database systems, operating systems, computer security, data networks, distributed systems, concurrency, and fault-tolerant computing.

It provides a perspective on computer system design, based on enforcing modularity. Client/service model, which is a widely used method of allowing modules to interact without interfering with one another, is discussed here. In this book, the network is only viewed as an abstract communication system that provides a boundary between the client and the service. Study the case studies and learn how to apply the principles and abstraction to tackle real system design problems.  Thus, you can answer all the above questions easily if you read the book thoroughly.

A great performance in System design interview can be highly rewarding for your career. It will reflect in your abilities to work with complex systems.
