Discuss the importance of policy-based management under domain network management?
Discuss the need importance of coordination. Why is it considered the Essence of Management? Management decision constitutes the most important thing that managers do. Given the significance and complexity of this activity, one would expect to find a literature in which there is general agreement as to its defining characteristics and dimensions. Such is not the case. Much writing that purports to treat various aspects of management decision takes place outside the organization or involves individuals who are not or are not likely to become practising managerial decision makers. The consequence of this diffused and disjointed approach is a general misconception of the essence of management decision. More specifically, there is a general lack of appreciation of what management decisions are, who makes them, and where they are implemented. Intends to correct these generic misconceptions by advancing a set of theories and concepts that embodies the essence of management decision. The assimilation of these perspectives and viewpoints should enhance the reader's conception of what management decision is and is not thereby contributing to higher levels of decision success in organizations of all types.
What is message control system?
A method for controlling messages in a software system. The method activates a report-handling module when a subroutine has a message to send. The subroutine passes an identification to the report-handling module. The subroutine then passes a message and message level to the report handling module. The report-handling module then determines the message level to be reported for that subroutine, the process from which that subroutine is sending messages and the message level to be reported for that process. If the message level of the message compares correctly to the message level of the subroutine and the process, the message is reported.
packet switching is use today
There are network sniffing programs available, (some which are free), that allow you to see all clients and gateways on your network. Do a google search for "network sniffers".
Which OSI model layer is responsible for the termination of connections between hosts?
There are in total seven layers in OSI model . OSI model layer that is responsible for the termination of connections between hosts is session layer . Session layer is responsible for the dialog control .
Are all link layer protocols that support IP have the same frame structure?
Link layer does not understand IPs at all, it operates with MAC addresses.
Are there enough local gyms in your area?
In my location there are a few gyms with two of them being highly specialized. One is a general gym where both sexes can go to get a workout on a wide variety of equipment. The second is a ladies only gym and the third is actually geared toward boxers.
What is the subnet address when ip address is 142.80.119.128?
The subnet Mask I presume you mean.
There is no single SET subnet mask for any IP
The subnet mask for most general home networks is 255.255.255.0
The subnet mask is identified by the third set of numbers in the IP address when converted to binary.
DHCP V6 works on SARR process where:-
S=SOLICIT message using multicast
A=Advertise message form sever side
R=Request
R=Reply
because ipv6 does not support broadcast.

Why LAN icon show not connected when LAN cable connect to PC?
The fastest check is to see the green light on the back of the PC and whatever other device you are connected to. When you unplug the cable the green light should go out. That indicates that the device on your end is seeing power from the other end. If the light is not on there is either a faulty device or a cable problem. If the light is on at both ends, and goes off when you unplug the cable you probably have a good hardware connection. If the cable is correct, there is more to check. The most common error is that the two devices are not configured to talk to each other. This is most often caused by an error in the speed and duplex settings. If one device is set to 10 mb and the other is set to 100 mb they will not talk and you will see the disconnected status. The same is true if the duplex (full/half) are set incorrectly. You may also have incompatible network protocols.
How many computer can connect crossover cable?
Only two computers, can be connected to a crossover cable, although three can be supported as well, if one has two or more Network Cards (NIC Cards) installed in one workstation. this kind of Network is Known as Peer-to-Peer.
What might cause a 100Base-TX network to experience an average throughput of less than 100 Mbps?
100 Mbps is a theoretical limit and never could be achieved. Also, if you are running half-duplex or/and shared channel it would decrease performance significantly.
What is the role of mobile IP in network?
Mobile IP has two addresses for a mobile host : one home address and one care of address . The home address is permanent ; the care-of address changes as the mobile host moves from one network to another.
Difference between stateless protocol and statefull protocol?
stateless Protocol:-
1).When stateless protocol is used between a server and the client, the server does not remember anything. It treats any message from a client as the client's first message and responds with the same effects every time
2). A stateless server does notkeeps state between connections.
=>So,When
you send a request to a stateless server, it does not create any objects that track information regarding your requests. If you "open" something on the server, the server retains no information at all that you have something open. A "close" operation would make no sense, since there would be nothing to close.
3). A stateless system can be seen as a box ,where at any point in time the value of the output(s)
depends only on the value of the input(s)
after a certain processing time.
4). A stateless protocol does not require the server to retain session information or status about each communications partner for the duration of multiple requests.
5). stateless sessinobean:can
not maintain the state,cannot
maintain the persistance(data
base),onece
sutdown
machine,we
cannot see that data,cannot
have the passivate,activate
states. ex:atm
mini statements.
Example =
UDP(User
Datagram
Protocol) , HTTP, NFS
Statefull
Protocol :-
1). Stateful
protocol means the server remembers what a client has done before.
2). .A stateful
server keeps state between connections.
=>
when you send a request to a stateful
server, it may create some kind of connection object that tracks what information you request. When you send another request, that request operates on the state from the previous request. So you can send a request to "open" something. And then you can send a request to "close" it later. In-between
the two requests, that thing is "open" on the server.
3). a stateful
system is like a state machine with "memory" as the same set of input(s)
value can generate different output(s)
depending on the previous input(s)
received by the system.
4). a protocol which requires the keeping of internal state is known as a stateful
protocol.
5). statefull
Protocol :- maintain the state,but
cannot maintain the persistance,once
we shutdown
the system the values stored in local hard disc,can
have the passivate
and activate states. ex:shopping
card
Example =
SMB, FTP,Telnet
What type of device is Ethernet?
Ethernet is not a device, it is software protocol. There is hardware to implement the protocol, e.g. NICs, switches, hubs, etc.

1 Name three types of Ethernet What transmission speed does each support?
(From: Jean Andrews CompTIA A+ 6th Edition pg. 846)
The three variations of Ethernet are primarily distinguished from one another by speed:
(1) 10-Mbps Ethernet, (2) 100-Mbps or Fast Ethernet, and (3) 1000-Mbps or Gigabit Ethernet.
The subnet id identifies which smaller network within a larger network (the subnetted network) the packet should be delivered to. The subnet id is part of the extended network prefix which is used for routing.
A router that supports two or more communications protocols, such as IP and IPX. It is used to switch network traffic between different LANs located throughout the enterprise as well as to switch LAN traffic to WANs.
There are 21 brown to 6 green, which reduced gives us a ratio of 7:2. (21 divided by three and 6 divided by three)
The ratio 7:2 describes brown to green. The ratio 2:7 would describe green to brown.
