Computer Network Tutorial

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 are the differences between StaticJsonBuffer and DynamicJsonBuffer?

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...

Detailed Analysis on Arduino UNO R3

Arduino UNO R3 Arduino Uno is a microcontroller board based on ATmega328P . It has 14 digital input/output pins 6 Analog pins a 16 MHz quartz crystal oscillator with USB connection ,a power jack , an ICSP(In-Circuit Serial programming) header and a reset button actually it has two reset buttons . Also Arduino uno has RX-0,TX-1 that is receiving and transmitting pins on board. Arduino uno contains AREF pin which means Analogue-Reference IOREF pin this pin is provides a voltage reference at which the microcontrller works 3-ground pins 3-Vcc pins Basically the purpose of creating an Arduino Uno is to Control the sensors and the actuators so that it can work accordingly the data which we provide with the help of software . Nowadays people using Arduino Uno in many fields it has very huge scope in the field of IOT(Internet Of Things). Also in my current project which is 2D-printer we have used Arduino Uno which sense the Data and according...

How to create a NAS using Raspberry-pi?

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 ...
