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.

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

  ACL (Access Control List) ACL is use for to set additional level of security into the router. ACL is a security that set-in router port ACL are of two type in router a.    Permit b.    Deny c.     Both statements must be set in Router. If Permit or Deny use in any network use wild card mask (opposite of subnet mask) ACL are of two type a.    Standard ACL   from (1-99) b.    Extended ACL from (99-1999) Standard ACL Standard ACL is used for source but apply in destination Its Range is 1-99 ACL is applying in router interface port. Packet transfer port is 2 type A.   Incoming B.   Outgoing ACL is set in incoming and outgoing port of router How to configure  First Diagram Basic Configuration And clock rate Go to first router in cli mode and type  No Router>en Router#conf t Router(config)#int s0/0 Router(config-if)#ip address 192.168.30.1 255.255.255.0 Router(config-if)#no shut Router(config-if)#clock rate 64000 Router(config-if)#exit Router(config)#int f0/0 Router(config-if)#ip addres

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.

OSPF(Open Short Path First) 1. It is dynamic routing Protocol. It is also known as link straight protocol 2. OSPF is classless routing protocol. Support CIDR Network. 3. OSPF protocol design and develop by IAB (Internet Articture Board) and IETF (Internet Engineer Task Force) 4. OSPF Route the packet up to infinity hope {infinity network support} 5. OSPF is use LSA (Link Stay Advertisement)      LSA are of 9 Type      LSA-1 is in CCNA     And other from 2-9 are in CCNP 6. OSPF Use Process ID, Process ID mask match between neighbors router 7. Process ID range is between 1 to 65535.  8. OSPF is use area no., Area no. zero is backbone Area 9. OSPF Configuration also support wild card mask. Wild card mask is just opposite of subnet mask    For EX.:- 255.255.255.0                   -255.255.255.255                  ————————                         0.0.0.255 NOW CONFIGURATION:-  Now Diagram Step#1 Basic Configuration:- Go to First Router Router>enable Router#configure terminal Router(conf
