Read MoreHow to Create a RAID 5 Storage Array with ‘mdadm’ on Ubuntu 16.04
In this article, we will learn how to create a RAID 5 Array configuration using the ‘mdadm’ utility.The ‘mdadm’ is a utility which is used to create and manage storage arrays on Linux with RAID capability where the administrators are having great flexibility in managing the individual storages devices and creating the logical storage with a high performance and redundancy.RAID 5 Array is a type where we implement by striping the data across the total available devices. Every component of the each stripe is calculated by parity block. If any device fails the parity block, it will use the remaining ...

Read More10 Ways to keep your Data safe in Cloud Environment
A “cloud” in the technological sense, can be defined as a huge online place for storing and accessing data and program files in the internet, instead of your computer hardware- like local disk.

Cloud environment is as safe as data stored in an individual data server.Cloud is the latest trend in technology and most of us store all data in cloud housed in Dropbox, Google Drive. Generally, people assume that all the data stores ...
Read MoreDifference between Linear and Non-linear Data Structures
Linear Data StructuresA Linear data structure have data elements arranged in sequential manner and each member element is connected to its previous and next element. This connection helps to traverse a linear data structure in a single level and in single run. Such data structures are easy to implement as computer memory is also sequential. Examples of linear data structures are List, Queue, Stack, Array etc.Non-linear Data StructuresA non-linear data structure has no set sequence of connecting all its elements and each element can have multiple paths to connect to other elements. Such data structures supports multi-level storage and often ...
