What occurs if you use an unterminated coaxial cable as a bus in a data network?
Echo-back interferes with the original signal
proxy ARP
Let me tell you one analogy. When you and your friend are talking via the phone, both phones must be off-hooked. (i.e. both of you are holding the phone handset.) For some reason, like one's phone has dead battery, the line has been cut off, someone accedentally hit the botton, your phone call will be ended. Only one side needs to have problem to loss the connection. The same goes for computer network communication. Both computers must be online in order to communicate eash others.
Why a network printer cannot be accessed by some users?
There are many reasons. The most popular is users are in different network groups.
What is the Difference between the TCP and UDP in computer networking?
An important difference is that TCP includes mechanisms for reliable data communication (lost parts of the communication are re-sent), UDP doesn't. TCP is used when such a reliable communication is important. When speed is more important than reliability, UDP is used instead. This is the case with phone or video communication over the Internet.

Is DHCP the same thing as NAT?
No.
DHCP (Dynamic Host Control Protocol) is a method of providing clients network information from a router or DHCP server. It can tell a host what their IP address is, what the gateway is, what the DNS servers are, WINS servers, etc.
NAT (Network Address Translation) is the technology used by a gateway that allows a private ip address to access information on the public internet.
For example, You have a router (10.0.0.1) that acts as a DHCP server and DNS server. Something connects to your network and broadcasts a DHCP request, and is then given an ip address (10.0.0.5 for example) and told where to go to resolve domain names.
That client wants to connect to google, it makes the request first to the name server through the gateway, and then information is sent back to the gateway. NAT Allows the gateway to get the information to the correct computer behind it even though it is not directly accessable. (Google can not directly access 10.0.0.5 and vice versa)
ARP is a protocol that maps MAC addresses to IP addresses for packet delivery and for finding out which device in a LAN has a given IP address.
False
What the dhcp server is on a computer and how to change it?
You cannot select which DHCP server is used because the server is found through broadcast. Also only one server is allowed per network segment, so only one should exist.
What are the differences between LAN and WAN?
LAN means Local Area Network, as the name implies its used for local areas such as in your home or office for sharing data, informations or play games etc.. and WAN means Wide Area Network, which is used for wide or broad areas to share data or get informations such as across a country. But to transfer data globally, across the world internet is used.
What level of the OSI creates packets?
Some textbooks say that the packet is fully created when it reaches the physical layer, although the actual final construction is layer 2 (Data link layer).
Then again, some textbooks will say that the packet is fully created in layer 2 and is transmitted out the physical layer as a frame.
To which network device or interface does the IP address 192.168.1.254 belong?
That is normally the IP address of a router
Choose this option if you want the server to respond only to known clients that have been prestaged. Prestaging a computer requires that an administrator create a managed computer account in Active Directory before booting the client so that it can be installed over the network.
Which tcp ip architecture makes use of ports?

In this chapter, we will take a look at the TCP/IP protocol stack to help us better understand how TCP/IP functions in the network. We'll look at the Department Of Defense (DoD) protocol layers and the Open Systems Interconnect (OSI) model to help us better understand how protocols and utilities function at various layers. We'll discuss the protocols that comprise the TCP/IP suite of protocols and look at some TCP/IP configuration and troubleshooting information.
At the end of this chapter, you will be able to:
· Discuss the protocols that support the Internet.
· List the layers in the OSI and DoD networking models.
· Describe the TCP/IP suite of protocols.
TCP/IP made early WANS possible. TCP/IP's robust set of protocols provided complete networking support to connect all hosts and sites and rapidly became the standard for such activities. Over time, the TCP/IP suite of protocols and utilities has become much more than just a standard-it has helped us usher in a new era of computing. We can now configure machines around the world and monitor events on distant computers. Although local area networking standards remained in the realm of proprietary vendor standards until the mid 1980's, they have changed so much since then that today there is nearly total interoperability in the TCP/IP world. With TCP/IP, we can connect to the world. Before we do that, however, let's look closer at what the protocol suite is capable of doing
Abstract
This chapter examines the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite in greater detail, analyzing its four layers and the core protocols used within each layer. Network administrators must have an understanding of the core protocols in the various layers and their functions to understand how networking applications work, how data is sent from one application to another, and how to interpret network captures. This chapter also discusses the two main application programming interfaces (APIs) that networking applications for the Microsoft® Windows® operating systems use and the APIs' naming schemes.

What does LAN and WAN stands for?
LAN stands for Local Area Network & WAN stands for Wide Area Network.
What prompt should a technician see after using the ip address 192.168.1.0 255.255.255.0 command?
The technician may see nothing at all (except for the next prompt) depending on the platform being used. Or, they may see an error message if there was a problem with the configuration.
Host 1 sent a syn packet to host 2 what will host 2 send in response?
This is used at transport layer of OSI for connection oriented services.
Its three way handshake.
1) SYN
2)SYN-ACK
3)ACK
hence SYN-ACK is the answer.
What is the difference between a Network address and Broadcast address?
When you set up a sub network you decide upon the subnet mask and this determines the network address (all zeros in the subnet portion of the address) and the broadcast address (all ones in the subnet portion of the address). When you assign the host addresses in your subnet, then you use the addresses between the network address and the broadcast address.
What Is a high-speed network that connects LANs in a metropolitan area such as a city or town?
MAN (Metropolitan Area Network)
