Wireless Network

Wireless Network means that network which has not need any wire for communication or which can transfer data and files wirelessly. In networking terminology, wireless network can be define as to any computer network where there is no requirement of physical wired connection between sender and receiver, but rather the network is connected by radio waves or by  microwaves to maintain communication. Wireless networking  specific equipment are used  such as NICs, APs and routers in place of wiresfor connectivity and which  give same or high speed .

Some Wireless Technology

Infrared Technology
Mobile phone
Wi-Fi
Bluetooth
Radio frequency

Types Of Wireless Network

WLANS: Wireless Local Area Networks
wireless LANs use radio frequencies that are radiated into the air from an antenna that creates radio waves. These waves can be absorbed,refractedor reflected by walls,water or also by any metal surfaces because of that it resulting in low signal strength.It means it got affected by surrounding environment.WLANS is temporary network can be formed by a small number of users without the need of an access point; given that they do not need access to network resources.


WPANS: Wireless Personal Area Networks
The two current technologies for wireless personal area networks are InfraRed (IR) and Bluetooth (IEEE 802.15). These will allow the connectivity of personal devices within an area of about 30 feet. However, IR requires a direct line of site and the range is less.

WMANS: Wireless Metropolitan Area Networks
This technology allows the connection of multiple networks in a metropolitan area such as different buildings in a city, which can be an alternative or backup to laying copper or fiber cabling.

WWANS: Wireless Wide Area Networks
These types of networks can be maintained over large areas, such as cities or countries, via multiple satellite systems or antenna sites looked after by an ISP. These types of systems are referred to as 2G (2nd Generation) systems.

Wi-Fi


Wi-Fi is a wireless networking device thats gives  a wireless network between  computers and other devices to communicate . It describes network components that are based on one of the 802.11 standards developed by the IEEE and adopted by the Wi-Fi Alliance. Examples of Wi-Fi standards, in chronological order, include:

Standard                  Maximum speed                 

802.11a                54Mbps                                   
802.11b                11Mbps
802.11g                54Mbps
802.11n                150Mbps
802.11ac                  800Mbps

How to connect two Laptops via mobile hotspot

-
If we want to transfer a file or a folder without any physical medium then we can use mobile hotspot as a mediatior. To connect two laptops we have to go through several steps. Steps:- first on the hotspot of mobile and connect to both laptops and connect to both laptops then open network and check devices if net is off then give manual ip in both laptop then check both laptops in network then share data from first laptop Steps:- First copy all the data in a folder --> go to folder properties --> click on share --> advance --> check mark on "share the folder" --> permission --> check mark on full control-->ok-->close Now go to another laptop-->network-->open another laptop-->and paste the data.

Supernet

Supernet Supernet is used for to merge multiple route into single router. Supernet is create max.7 network Supernet is covered in into small size network Supernet create in 4 step’s 1. First convert all ip into binary 2. Now set the end operation end operation condition’s. operation are       a. all bit is one then output is one       b. all bit is zero then output is zero       c. if one bit is one and second is zero then output will zero 3. After set end operation now create new ip 4.Count common bit and create subnet mask For example                       172.16.111.0                       172.16.112.0                       172.16.113.0  1. Now convert it into binary.       10101100         00010000              01101111        00000000 10101100         00010000              01110000        00000000 10101100         00010000              01110001        00000000 2. Now set the end operation end operation condition’s and create new ip  10101100         00010000               01101111

What is network ? A network is a collection of multiple computers or Other hardware devices that are connected together, either physically or logically using hardware and software. What is networking? Networking is the process of sharing of data between different devices,and it also involves Designing, implementing, upgrading ,managing and working with network technologies.  Types of network 1.       (Lan) Local area network 2.      (man) metropolitan area network 3.      (Wan) wide area network 4.      (Can ) campus area network 5.      (Gan) global area network 6.      (Pan) personal area network Local Area Network     A computer network that links devices within a building or group of adjacent buildings, especially one with a radius of less than 1 km. Metropolitan Area Network A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but s
