How many bits are borrowed from a class B host address to create 30 new subnets?
5 bits are necessary to create up to 30 subnets.
The Physical layer is responsible for the actual hardware connection. The physical addressing is handled by the Data Link Layer.
Where is WAN located in a limited area?
WAN is not in a limited area, it is a wide area network that can be accessed anywhere, and it is temporary.
ICMP protocol.
What does an X on the input to a hub represent?
You will see an "X" on many of the switch and hub input ports, indicating that this is a crossover connected input. This means that transmit and receive pairs are internally swapped to maintain proper signal alignment of the TX and RX pairs.
How do you make a computer to computer network?
The basic components of a network are the clients and the network hardware such as the switch that connects the hosts together. Each client is required to have a network interface card and must be configured with the network IP settings that the admin has configured for the network. Once all the lower level settings have been configured you need to configure the computer to join either the workgroup or the network domain that is configured on the network.
At what layer in the osi model would you find protocols such as rip and ospf?
OSPF and RIP are used in the network layer of the ISO model.
What are some issues with physical isolation of a LAN from the rest of a network?
Well, there is no interaction from the outside world. No file sharing, Etc.etc. Imaging you disconnected your computer from the internet. Your limited to what the machine in your isolated lan has to offer.
A tcp connection is in 'established' state.................?
It is established after the 3-way handshake is complete and the channel is open between a sender and a receiver.
Why ip is called connectionless?
IP is connectionless because you don't want routing to reply to every routing request; it would slow things down to almost a stop. The router has to assume that the packet arrives where it was sent.
What layers of the OSI model are implemented in hardware?
The physical and link layers (layers 1 and 2) are implemented in hardware. The remaining five layers use these two layers to communicate across a network, and are done by software.
What are reasons why LANs are segmented?
LANs are segmented for the following reasons:
- Keeps traffic isolated on certain segments - that way a busy LAN segment cannot overload the entire LAN.
- Security - some packets are contained in the LAN segment and the rest of the network does not see the packet at all
- Legacy protocols - some older protocols may be in use in a certain part of the network but there is no reason for the entire network to see the packets they cannot understand
- Better troubleshooting - it is easier to identify where the problem is if the network is segmented
- Allows for better scalability if you need to add clients to a part of the network
Configuring a workgroup is easy - give the workgroup and name and use that name in the workgroup section for the computer identification. The other choice is for a client-server (domain) based network. Therefore you only have two choices for computer identification; either as a workgroup or as a domain (client/server).
