Storage Virtualization
Storage virtualization is an abstraction of physical storage devices. It is base for flexible, scalable and reliable storage infrastructure. Storage virtualization is not a new technology; it is around us for many years. Technologies like Redundant Array of Inexpensive Disks (RAID), Logical Volume Manager (LVM), and Network File Systems like Andrew File System (AFS), Coda File System and Global File System (GFS) have played a significant role in storage virtualization. These technologies can combine individual relatively small physical volumes to build up huge virtual volumes or dynamic disks for Scalability and reliability.
Redundant Array of Inexpensive Disks (RAID), Logical Volume Manager (LVM) and Enterprise Volume Management System (EVMS) are limited to a single server at which Physical Storage device reside. Although some RAID controllers are dual portable, which allows multiple computers can access to same volume group and associated filesystems. Performance and reliability of this model is actually depends upon type of filesystem in use and how the filesystem is mounted on.

Introduction to C++
C++, as we all know is an extension to C language and was developed by Bjarne stroustrup at bell labs. C++ is an intermediate level language, as it comprises a confirmation of both high level and low level language features. C++ is a statically typed, free form, multiparadigm, compiled general-purpose language.
C++ is an Object Oriented Programming language but is not purely Object Oriented. Its features like Friend and Virtual, violate some of the very important OOPS features, rendering this language unworthy of being called completely Object Oriented. Its a middle level language.

Introduction to R
R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.
R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity.
One of R’s strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control.
R is available as Free Software under the terms of the Free Software Foundation’s GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS.

what is Brute forcr hacking/attack?
Brute force (also known as brute forcecracking) is a trial and error method used by application programs to decode encrypted data such as passwords or Data Encryption Standard (DES) keys, through exhaustive effort (using brute force) rather than employing intellectual strategies.

We all know default Windows programs opens as a "Normal" window size, that means its dimensions won't fill the entire screen or full screen. While users simply maximize the window's size by clicking the middle icon in the upper right-hand corner, but many people don't like having to repeat the action every time when starting a windows program.Follow this step below to proceed force Windows program open as a full-screen mode.
▪️Right click your mouse on any Windows shortcut icon and click Properties.
▪️In the Properties window, click the Shortcut tab.
▪️And then locate the Run: section and then click the down arrow on the right hand side.
▪️In the drop-down menu, you will see Maximized.
▪️After choose to Maximize click apply, and then click ok.
