Q-1 Which layer of the OSI model is responsible for reliable connections? Q-2 What is the difference between acknowledgments and handshaking? Answer: Handshaking is used to negotiate the properties of a connection that is being established.
Any data packet coming from one port is sent to all other ports. It is then up to the receiving computer to decide if the packet is for it. Imagine packets going through a hub as messages going into a mailing list. The mail is sent out to everyone and it is up to the receiving party to decide if it is of interest. The biggest problem with hubs is their simplicity.
Since every packet is sent out to every computer on the network, there is a lot of wasted transmission. This means that the network can easily become bogged down. Hubs are typically used on small networks where the amount of data going across the network is never very high.
A bridge goes one step up on a hub in that it looks at the destination of the packet before sending. If the destination address is not on the other side of the bridge it will not transmit the data. To build on the email analogy above, the bridge is allowed to decide if the message should continue on.
It reads the address bob smith. If there isn't, the message will not be transmitted. Bridges are typically used to separate parts of a network that do not need to communicate regularly, but still need to be connected. A switch steps up on a bridge in that it has multiple ports. When a packet comes through a switch it is read to determine which computer to send the data to. This leads to increased efficiency in that packets are not going to computers that do not require them.
Now the email analogy has multiple people able to send email to multiple users. The switch can decide where to send the mail based on the address. Most large networks use switches rather than hubs to connect computers within the same subnet. A router is similar in a switch in that it forwards packets based on address. This allows the network to go across different protocols.
The most common home use for routers is to share a broadband internet connection. The router has a public IP address and that address is shared with the network.
When data comes through the router it is forwarded to the correct computer. This comparison to email gets a little off base. This would be similar to the router being able to receive a packet as email and sending it to the user as a fax.

AnswerStatic routes are routes that an administrator manually enters into a router. Dynamic routes are routes that a router learns automatically through a routing protocol. Also known as the gateway of last resort, a default route is a special type of static route with an all-zeros network and network mask. The default route is used to route any packets to a network that a router does not directly know about to a next-hop router.
Routing is the process of finding a path on which data can pass from source to destination. Routing is done by a device called routers, which are network layer devices. The job of the Data Link layer is to check messages are sent to the right device. Another function of this layer is framing. When a switch receives a signal, it creates a frame out of the bits that were from that signal. With this process, it gains access and reads the destination address, after which it forwards that frame to the appropriate port. This is a very efficient means of data transmission, instead of broadcasting it on all ports.

In addition to CCNA exams, professionals must pass either four separate exams, or a composite exam along with two separate exams. A postal address has three components that can be used to deliver mail: state, city, and street. A phone number has an area code and exchange. At the core layer, mail can be delivered to the next post office based on only the state or city and state information.
There are a lot of opportunities from many reputed companies in the world. Describe why postal addresses and telephone numbers are routable. What is the purpose of a default route?

Answer : Routing is the process in which items are forwarded from one location to another. Routing is a hop-by-hop paradigm. Routing is a way to learn and maintain awareness of the network topology.
