Introduction to Cybersecurity

This cute little fella is the mBot a do-it-yourself educational robot kit from robotics experts Makeblock. Built around the Arduino open-source platform, it's designed to induct kids into the fields of robotics and programming. The company chose to build around the concept of STEM education: science, technology, engineering mathematics. Specifically, it helps children get an early start into these disciplines. There are two versions of the mBot: a Bluetooth version for home use and a 2.4 GHz Wi-Fi version, which is designed for classroom use. Everything that you need to build it is in the box in a nutshell, you need to assemble it using the precise instructions provided and add batteries. There are 45 pieces and it's easy to put them together in about 15 minutes. It's neatly packaged and consists of very high quality materials. Every little part that you need from the main Arduino board, DC motors, to each screw, cable and even a set of tools is in the box. It comes pre-programmed but it's also designed to be tinkered with. Parent of pre-teens might be familiar with Scratch. It’s a free, graphical based programming language developed by MIT Media Lab. Well, Makeblock has built their own version for this and called it mBlock. The idea behind mBlock is that younger children can start out with graphical programming and move on to text-based programming as they become more advanced. Ultimately, once you put everything together, mBot can move around and avoid obstacles on its own, follow a line on the ground or just accept commands from the supplied IR remote controller. With the Makeblock app, you can control the robots wirelessly. For children, especially, it can be a surreal experience: actually building something out of tiny parts and seeing it come to 'life'. And there's no limit to what you can do add more parts, add another robot to play games or program your own actions. This is what will inspire the next generation of engineers.

Multitenant Database consolidation is the process of consolidating data from multiple databases into one database on one computer. Starting in Oracle Database 12c, the Oracle Multitenant option enables you to consolidate data and code without altering existing schemas or applications.Starting in Oracle Database 21c, a multitenant container database is the only supported architecture. In previous releases, Oracle supported non-container databases (non-CDBs).CDBA CDB contains one or more user-created PDBs and application containers.At the physical level, a CDB is a set of files: control file, online redo log files, and data files. The database instance manages the files that make up the CDB.PDBsA PDB is a portable collection of schemas, schema objects, and nonschema objects that appears to an application as a separate database.At the physical level, each PDB has its own set of data files that store the data for the PDB. The CDB includes all
