computer Networking- CCNA part 4 of Segment 1 (Types of Network)

Hello once again ,, i am Vasu Birla ,, and today we will discuss about second method of classification of Network .

2. Area of networks.

..according to this method Network are classified in following types

PAN- personal area network
LAN - Local area network
MAN- Metropolitan area network
WAN - Wide area network

(i)..PAN - personal area network- It is a Small computer network. This network in used within 10 meter of area only. it include wired and wireless medium,, example ,, Two pc cab be connected directly by single cable and fax machines , printers , Telephones

and in wireless Bluetooth is the best example for PAN. (Wireless headphone, wireless keyboard, Mouse)

PAN

(ii)..LAN - Local area network- It is a network which is used for small area around 100 meter like small office , Home, building and school ,,but it can be extended after 100 meter with help of Switches but Generally LAN is for 100 meter area. Ethernet Cable is used for this network,.

LAN

(iii)..MAN- Metropolitan area network- It is group of LANs . it should be in single town if we have two buildings in different area so we can connect it through MAN using switches .

It used high capacity backbone technology like optical fiber cables and should be used in limits of city.

MAN

(iii)..WAN- Wide are Network- It is a world wide internet it is group of LAN , MAN, WANs .

It covers large physical distance . example of WAN is Internet.

WAN

Hare krishna ,,, ,we will discuss further bye ,, ,

How to deploy NodeJS app on server with Apache2 and acess it with Server IP addresss - Node JS deploy project Live.

hello friens , This is Vasu Birla , in previous post we have seen the deployement of NodeJS app on AWS instance server instance but AWS server is expensive than other servers . SO today we will use simple Ubuntu server for making Live out Project using Apache2 . At the end you will be abe to access your NodeJS app using server IP address from anywhere .. 1. Login to your server using SSH terminal . (in AWS part i already explained how to do this ) -> Open your putty in hostname put your server IP - login with ssh username ->root and password (if you dont have root username and pass ask your provider or reset it from cpanel or hosting panel ) 2. after login - on terminal you can Put your project anywhere. There are two ways to put your project folder on server location (i) - > using Github - (very popular and easy to track your everyday code changes to your project folder) you can push your entire project folder to git-hub and and

Part 19- Router (Networking Devices)- Computer Networking- CCNA

Hello friends...i am Vasu Birla and today will discuss about the most important Networking Device ..Router. so let's start... ROUTER Router is a device which connect two or more networks together, which is why router is also known is Inter-networking device also. Inter-networking means two or more networks are connected together with the help of router. one more thing router is just like a computer but it is designed for routing only, our computer can be router also but that are software router while hardware router which are specialize for routing is more efficient and fast than software router. There is a Operating System installed on router which get moves data from one network to another network with the help of routing table. Router does work on Network layer or Layer 3 of the OSI model. Cisco Router There many companies which manufacture Router but main companies are - Cisco , Juniper , HP, 3com and Nortel Functions of Router

Part 16- HUB (Networking Devices)- Computer Networking- CCNA

hello friends , Today we will discuss about the second Networking Devices Ethernet HUB. HUB Hub is a centralize device via all devices (computers, printers etc.) are connected with the star topology. Hub connects other multiple devices together and helps to make connectivity mutually so that they can share and transfer data to each and every devices which is connected to that hub. Hub does work at the first layer means at Physical layer of the OSI Model. Hub has many ports, and each port works like a repeater so Hub is also known as Multiport Repeater. A Hub Types of Hubs. there are three kind of Hubs. Active , passive and Manageable hubs. 1. Active Hubs - These hubs regenerates and amplify the signals to keep them strong. one more thing there is electricity needed in the active Hubs. 2. Passive Hubs- Passive Hubs simply forward the received signals. this type of hub does not make pure signal or regenerate so these passive hubs doesn't n
