What are the parts of a pdu that are always present in any pdu?
The Header and the payload The Header and the payload
How you can communicate two lan segments?
People use servers for such purposes. The server should have at least two network interfaces. Using DHCP server options you can connect two and more networks together.
List of the companies using bus topology?
No one knows, since this is not published information. Companies are not likely to publish anything about their network topology, since it may be considered a security risk.
Ethernet and Star
Microsofts Remote Desktop Client (RDP)
or
Citrix
Which IP address is reserved for Automatic private ip addressing?
I think you're thinking of the protocol used to automatically assign IP addresses? An IP address does not assign an IP address, and IP address is a node on a network where data can be sent or received. The protocol used for automatic assigning of IP addresses would be DHCP (Dynamic Host Configuration Protocol).
What are three features of CDP?
• tests Layer 2 connectivity
• enabled by default on each interface
• provides information on directly connected devices that have CDP enabled
Is there a program similar to network magic but free?
Linksys Easylink Advisor the precursur to network magic is free, it's larger in size but quite similar
Who developed the telenet protocol?
The original founding company, Telenet Inc., was established by Bolt Beranek and Newman (BBN) and recruited Larry Roberts (former head of the ARPANet) as President of the company, and Barry Wessler. GTE acquired Telenet in 1979.[3] It was later acquired by Sprint and called "Sprintnet". Sprint migrated customers from Telenet to the modern-day Sprintlink[4] IP network, one of many networks composing today'sInternet. Telenet had its first offices in downtown Washington DC, then moved to McLean, Virginia. It was acquired by GTE while in McLean, and then moved offices in Reston, Virginia.
Under the various names, the company operated a public network, and also sold its packet switching equipment to other carriers and to large enterprise networks.

How much important is a processor in a client computer of a client-server network?
no much because all the work is processed at the server level and result are sent to client
any device in the collision domain whose backoff timer expires first
Several reasons to divide a network into subnets?
Networks are divided into smaller subnets to reduce the size of broadcast domains, but mainly for administrative purposes - so you can control who has access to what, for example.

The technology is used by private network ranges that has extended the useful life of Ipv4 addressing and slowed the adoption rate of Ipv6 is NAT . NAT is short for network address translation. NAT provides mapping between private and universal addresses.
Is it possible to configure router to assign the same ip to all my computers?
It's not. Even if you do your network will never work.
The address resolution protocol (arp) is a protocol used by theInternet Protocol (IP) , specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol. The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer. It is used when IPv4 is used over Ethernet.
There are four types of arp messages that may be sent by the arp protocol. These are identified by four values in the "operation" field of an arp message. The types of message are:
- ARP request
- ARP reply
- RARP request
- RARP reply
If a host with the IPv4 address 10.10.10.123 and MAC address 00:09:58:D8:11:22 needs to send a packet to another host with the IP address 10.10.10.140, but does not have its MAC address, then the host sends an ARP request to resolve the unknown address.
What are three characteristics of network reliability?
Redundant hardware provides enhanced reliability.
Fault tolerance is a measure of reliability.
The longer the MTBF, the greater the reliability.
Convert the subnet mask to binary: 11111111.11111111.11110000.00000000
The zeroes tell you which bytes indicate the host; in this case, 12 zeroes allow for 212 = 4096 different IP addresses within the subnet. Of these, two (the first and the last) are unusable for a host, so you have a maximum of 4094 hosts.
In essence, a DNS server is simply a database that links meaningful names (known as host names), such as http://www.microsoft.com, to a specific IP address, such as 192.168.124.1. So pretty much DNS or the Domain Name System are the guys who know everyone by their real name, so when you type in a 'nickname' (host name) eg: Yahoo.com in your address bar, they say 'oh you mean 209.191.122.70' and your computer now knows who you need to message. Also, on Windows you have something called a Windows Host File - your own little database similar to this so you don't always have to go through the DNS.
The DNS has a little more function than this but this is its main use. Also it sometimes is not as simple as contacting one DNS server and getting IP right off. You may type in mail.yahoo.com and the first DNS server contacted says 'oh well I only know yahoo.com' so he sends you to another DNS server, perhaps yahoos DNS server, this is where you find out IP for mail.yahoo.com. This is why sometimes you will go to a page and it may take a second, this is because it may have to go through multiple DNS servers before someone knows who you're talking about.
As for DHCP, according to TCP/IP every client (your computer, your phone, etc, anything on a network) has to have a unique IP address and subnet mask. At one point in time, people had to do this manually - and considering you cannot have duplicates, it would be very strenuous and a pain to do. That's where DHCP comes in. DHCP does all this automatically. Each client gets a unique IP address, subnet mask, and other IP information such as default gateways and the IP addresses of WINS (Windows Internet Name Service) and DNS (Domain Name System) servers. DHCP makes certain that no clients have duplicate addresses, and this entire process is invisible to network administrators and network users.
