  What is a Computer Network? Computer networks is bunch of computers connected through optical cables, wires and fibers so that it interacts with each other through networks. The goal is to share the content and the information among the system of same network or other. In computer networks there are different types of networks that shares the information among each other they maybe simplex or complex ones.

Tutorial Information(Day-1):- Computer Network tutorial provides basic and advanced concepts of Data Communication & Networks (DCN). Our Computer Networking Tutorial is designed for beginners and professionals. It Inculdes all the topics such as introduction, features, types of computer network, architecture, hardware, software, internet, intranet, website, LAN, WAN, etc. What is Computer Network? Computer Networks is set of connected Computers in a small or large areas. A node can be anything printers ,Computers ,WiFi any devices which are capable of sending and receiving the signal .  In these devices routers ,brouters ,ethernet plays an essential role in working of the networks by using computer networks one can send data securely using the network there are three types of network:- 1. LAN(Local Area Network) 2. WAN(Wide Area Network) 3.MAN(Metropolitan Area network)

What's a NAS? Network-attached storage allows you to share files from one, always-on device throughout your house. With a NAS on your network, you can use it to store your movies and play them from multiple Kodi boxes, store backups on it from your PC, or use it as a BitTorrent box that seeds your files 24/7. Sure, you could do all this with your main PC, but a NAS is lower-power, and it is designed to be run day and night, even if your desktop is out of commission. Once you start using one, it's hard to go back. There are plenty of ready-built NAS devices out there, from companies such as Synology, QNAP, and Asustor. Just buy one, pop in a hard drive, and you're off to the races. But they can get expensive quickly, and if you aren't sure whether a NAS is for you, it's hard to justify the investment—especially if you want something that can grow with your storage needs. The Raspberry Pi, on the other hand, is such a versatile little board that it can act as a cheap ...

   StaticJsonBuffer ArduinoJson  uses preallocated memory to store the data and this is possible due to StaticJsonBuffer. If one has to use this library then firstly they should create t he StaticJsonBuffer just like: StaticJsonBuffer<200> jsonBuffer; then it creates an  memory of 200 byte size which creates allocated memory in the system for storing the data static as the name tells it has fixed in size type of memory.Also we cannot reuse the memory once it gets allocated.it has high speed performance. DynamicJsonBuffer This library supports DynamicJsonBuffer since it has parameters for dynamic memory allocation but it will be more useful if we use this buffer in the machine having memory more than 10KB of RAM. to use this syntax is just similar. DynamicJsonBuffer jsonBuffer; This will create one dynamic memory for the system so that it can allocate it more precisely.its size is variable it stores the data in heap.while storing it take time and its somehow pro...

Mini CNC(Computerized Numeric Controller) using an Arduino :- Step1 :-   Collecting all the necessary items from the market includes the following list:- Arduino UNO(R3) L298N Two old DVD drives Step2 :-   Creating the structure of the project.As i was using the old DVD drives here so i was used to design all the layout of my printer on the DVD drive also we have  used some type of 'jugaad' here to create the x axis of our CNC printer since i have less timings to complete our project and also to lower the cost of our project we use this wooden cardboards which i have cutted in a proper manner so that when we give the input it runs on x-y axis.               Basic structure of my project Components Used :-       HARWARE REQUIREMENTS :- Old DVD writers L298N Stepper Motor Drivers Connecting Wires Servo motors Arduino UNO         SOFTWAR...
