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

LAN network           2.     To create WAN network There are three type of line/cables. a.    DSL b.    Leased line/serial line/dedicated line c.     Frame Relay---à under 100KM DSL (Digital Subscriber line): -      1.     DSL line is used to transmit digit data our telephone line.      2.     DSL provide by telecom company      3.     DSL line generally use to connect public network Leased Line: -     1.    It is also called serial line or dedicated line     2.    It is use for to connected private network     3.    It is 20/7 heavy data transfer media     4.    These lines provide by telecom company (ISP)     5.    In these lines there are two protocols are used to help in traffic. a.    PPP (point to point protocol) b.    HDLC (High level Data link control protocol) c.     PAP (Password Authentication Protocol) for protect data Frame Relay 1.    It is called Packet Switching Technology 2.    Frame Relay work on packet Switching Te
