Intro to Virtualization...

Virtualization is used to extend my usage to next level, for example any pc could run only a single operating system at a time, so whatever may be its configuration, here comes the problem the physical resources is underutilized, here the physical resources include storage, ram, processor, etc. If its that’s not matters a lot, but when it comes to distributed system and servers it matters much more than we think, imagine you are planning to host a website in a host server, the host can have only a single IP (Internet Protocol) and in that only one DNS can be attached, and the host’s memory, processor and storage cannot be shared, which leads to increase its cost. For example, GODADY has 10K clients, to host them if it needs 10k host machines(computer). Can you imagine the cost for maintenance and its power consumption? OMG! Its very high. So here comes Virtualization which allows you to run multiple operating systems with unique IP and properties by creating multiple VM (Virtual Machines) on a single host. These VM share the physical resources of the host. So GODADY no need 10K hosts to host its clients, it can host them in 1K are lesser than it based on the requirements of its client. Simply I have my PC with the configuration 1 TB of storage and 8 GB of RAM with i5 processor, now I can run only the windows operating system with a single IP which has minimum requirement than my configuration so, my memory, storage and processor get underutilized to overcome this I used virtualization concept and install Ubuntu, Thunderbird, etc., by creating virtual machines. This can be achieved by various tools provided by the giant in this field called VMware.

Failed even in Love..........

Hi, Once again sorry for my long gap. I actually had no idea about what to blog. Guys from now I'll post minimum one blog per week. thank you for all who asked me to continue my blog they are my motivators. So, I wish this could be a inspirational blog.

I never succeeded in any new skills at the very first attempt even in my love but not in my exam's. Nothing in the world is born with skills. They develop their skills after the birth. Even the new born of fish learns to swim after few seconds. What made it to acquire it...

OOP Encapsulation with Modifiers..

In this blog we can know about why we go for JAVA?. Java is a language known for object oriented features and its network support. Here object oriented is achieved by three concepts Encapsulation Inheritance Polymorphism but Java is not pure object oriented because of its support to primitive data types(explained later..) like int, float,...to overcome this JAVA has loaded with wrapper class( know more ). Encapsulation, we had come across the word "capsule" many times in our life. capsule is nothing but a outer protection(cover) used to protect the something from external factors. example the medicines usually come with a capsule to protect the chemicals inside it. Similarly the encapsulation is used to wrap the code or data from intruders in order to ensure its security. It can be achieved from mod...

My First Blog !

Arrays using Pointers..

In this blog let’s try to understand about pointer. So, what is pointer?... pointer is thing that used to point something in a group. For example, Here, the pointer is used to point the temperature in the gauge. Similarly, in computer the data gets stored in memory and each data is assigned with an address in the memory. So, the pointer is used to point the data, in other words pointer contains a memory address of that particular data. (int a = 10; here the ‘a’ indirectly act as a pointer which has the value ‘10’.) Now we can see that how arrays are similar with pointer. We know that array is a continuous block of memory that stores multiple data of same kind. Let’s have a close look In c program pointer a declared with ’*’ symbol followed by a variable (eg : int *ptr). int a[10];---------------------------( 1 )------------------> this array stores 10 integers at max, here all elements in array is referenced with the variable ‘a’. which is more...

MongoDB with Php part 01

In this blog we can see how to install mongo db in windows and connect with compass and how to acess mongo using Php with composer. Follow me @ facebook @linkedIn Installing MongoDb: 1) download mongodb from its official site..( click here to download ) 2) click the .exe file and mongodb gets installed. 3) now goto the parent directory in which monodb is installed and create a directory called 'data' and inside the 'data' create a sub directory called 'db'. 4) now to intialize mongo variable goto the installed directory usually it will be "C:\Program Files\MongoDB\Server\3.6\bin" nad copy that path. 5) goto system properties->advanced system settings->environmental variables in this add this path as a user variables. 6) now open a terminal and type "mongod". it starts the mono database running on local host on the default port 2701.. 7) now open a new terminal and type "mongo" it connects with your mo...
