In this post “Top 10 coding problems of important topics with their solutions ” are written. If you are preparing for a coding interview, going through these problems is a must.


There are about six major conceptualizations of memory that dominate today’s programming. Three of them derive from the three most historically important programming languages of the 1950s — COBOL, LISP, and FORTRAN — and the other three derive from the three historically important data storage systems: magnetic tape, Unix-style hierarchical filesystems, and relational databases.


ASP.NET Core includes the native ability to modify how an application behaves (and what it displays) based upon the environment it is currently executing in. This ends up being quite useful, since now we can do things as simple as not showing the error page to people using the application in a production environment. But it requires just a tiny bit of setup, and some knowledge of how environments are controlled.


Let’s say you want to adopt a microservices architecture for your application. You want to break your application down into a number of smaller services which you can scale and deploy independently of each other. You also want to do this without directly managing the infrastructure (either physical boxes or virtual machines). Service Fabric may be a good option.


Most platforms have similar glossaries or barriers to entry. There's TLAs (three letter acronyms) in every language and computer ecosystems. Don't get overwhelmed, start with Need To Know and move slowly forward. Also, remember YOU decide when you want to draw the line. You don't need to know everything. Just know that every layer and label has something underneath it and the whatever program you're dealing with may be in a level you have yet to dig into.


Microsoft Azure is generally available in over 30 regions around the world. Each region is home to a vast array of servers hosted within 1 or more datacenters. This is something that’s very apparent in Azure; especially since you need to choose a specific Azure region to host services in. However, something that’s not quite as apparent is the concept of Azure Region Pairs. Specific Azure regions are paired together.
