In my experiences with armored cables such as MC,HCFC the bending radius of the conductor inside is much smaller than the radius you could bend the armored casing. in other words the clad casing is going to break Which could potentially damage the conductors inside and should not be used. As always electrical wiring is not a hobby and should be left to licensed electricians who follow NEC codes and local codes
client warfare is where one industrial country supplies another group of people in order to help them win a war. the supplying country and the client generaly have poltical adjendas in commin and the opponent does not. the opponent may be a client of another country also. The real example isTHE usa AND THE SOVIETS. the usa supportes Israel . Israel was the largest anual recipient of american aid untill around 2004. Russi supported palestinians with weapons and aid also. it was a big concept during the cold war. they used others battles to show power and subliminaly compete with eachother for political reasons
UPD belongs to the Transport layer of the OSI model along with TCP. While IP belongs to the Network layer of the OSI model. So they are on different levels. The UPD does not check the data for errors, whether packets will be received or does any sequencing, that is done by TCP. UPD is useful for large amounts of informaton to pass thru like audio and video because it does not slow it down with checking. IP is a totally different animal. It belongs to the Network layer and provides information about how and where datra should be delivered including data source and destination address.
Yes and half the stud width.
Wireless network attacks What type of attack is most common?
It would probably be packet sniffing, although you do need to be rather close to your target to do that. My personal weapon of choice for penetration testing I have owner's consent though is a man in the middle attack where I get between the computer and the firewall and tell each one that I am the other to let them send me information. Also from afar most people would just Denial of Service your network which is sending so much information that it can't serve your users.
A protocol analyzer or packet analyzer is a hardware or software tool used to intercept digital communications occurring over a portion of a network.
Examples of packet analyzers (hardware and software) products are:
Wireshark (Ethereal)
tcpdump
Netscout
snoop
Why is it important to use virtual private network to send sensitive data?
Because now a days it is cheep and from vpn you can send the data securely. Because VPN split the datas into smaller cells as well send it through different routes.

packet switching is nothing but the process of converting frames of data into small packets by using some of the algorithms...............
How do you install an electrical circuits wiring using armored cable?
Same installation as non armored cable.
How does the application layer on a server usually process multiple client request for servers?
The process can happen within a few limitations. The first is bandwith. According to the speed that the server uploads, the number of users logged on to the server may grow until the bandwith is maxed. Then after completion of a users request then the next user can log on. On the server itself each request is stored into memory(were talking a process that happens in nanoseconds). Once the request is repopulated or times out then the next users request is resolved. Under multiprocessor abilities these action may transpire simultaneously and at alarming rates depending on size and speed of the processor. The application itself usually is not posted to run on the server unless it has been tested. Newer calls to java and .net services are making the software side much more seemless.
uses support from lower layer functions to distinguish between connections to the service

What is cost of class a and class b public address?
For an institution or even an individual, the cost would be whatever the ISP charges to connect using that address.

A P2P network needs network operating system software installed on every node?
False. In P2P network network is only set up once, other computer just have to connect to it.
What are the advantages of Class A network over Class B and Class C?
A class A network has more IP addresses - you can connect more hosts on it.
A class C network has 256 IP addresses (of which you can use 254), a class B network about 65,000, a class A network about 17 million.
More specifically, a Class A network can have 16,777,214 usable host addresses per network whereas a Class B network can have 65,6534 usable host addresses per network.
Another advantage is the ridiculous amounts of subnetting you can do. For example, in a Class C network, you can't borrow the same number of bits as you can with a Class A because you only have the last octet to work with for the host portion. With a Class A network, the last three octets are the entire host portion, so you have 24 bits to work with for subnetting (technically 23 since you can't subnet down through all available bits and have no bits left for hosts =p). Due to the amount of subnets you can have and the 16+ million hosts you can potentially have on the same network, Class A networks are reserved for super big applications (ISPs and gigantic companies).
Why does a network host need to broadcast an ARP request?
A host on a network needs to broadcast an ARP request to advertise its Mac address. The networking world is very chatty in nature and when a new network host is available it immediately broadcasts its Mac address as with a ARP message.
Also when a particular network host needs to send a data packet to another network host available in the same LAN whose Mac address is unknown, the first network host sends out a ARP message requesting for the destination network hosts MAC address.
