Can you plug an Ethernet cable into a phone jack?
No it just looks that size it is actually larger and will only give you the internet from modem or router
What is the protocol of the Emergency Alert System?
The protocol of the Emergency Alert System is all broadcast stations including satellite,internet,and radio must be able to receive the alert messages.
What is the problem and its solution in multiple access transmission in networking?
that of determining who gets to talk (i.e., transmit into the channel), and when.Computer networks similarly have protocols - so-called multiple access protocols - by which nodes regulate their transmission onto the shared broadcast channel.
There are seven type of OSI reference model:-
Layer 7: The application layer Layer 6: The presentation layer Layer 5: The session layer Layer 4: The transport layer Layer 3: The network layerLayer 2: The data-link layer Layer 1: The physical layer
What is advantages of twisted pair cable?
The advantages of Twisted pair cable are
1)Data transfer rate 100mbps
2)Can support more length(not sure in numbers)
3)Less cost
Speed: Ethernet can send up to 10,000mbps (10 Gbit/s) over TP cable.
On run length.
The above maximum is for Ethernet signalling, and this is required to ensure that Ethernet's collision-detection function will work correctly.
For voice-grade telephone, the run length is only limited by line loss due to cable attenuation.
Remote locations and rural/country properties are commonly many kilometres from local telephone exchanges, and the cable runs will be straight connections with no intermediate "booster" amplifiers/repeaters.
ADSL provision complicates the matter. ADSL runs at maximum speed for cable lengths under about 2.5 kilometres, ADSL2 begins to drop off at about 1.3 m (under a mile).
After that, their speed drops off rapidly, with a maximum of some 6.5 km (about 4 miles) the absolute limit for ADSL2 service.
Explain the purpose of a MAC address How is the address used How many bits in the address?
The Media Access Control address (MAC address) is a 48 bit number that identifies equipment (computers, printers etc.) connected to a network - these connections are called Nodes. The Mac address number is usually set by the manufacturer of the equipment.
The difference between the niprnet and siprnet?
Both are Department of Defense computer systems.
NIPR is the Non-classified IP Router Network for sensitive but unclassified information.
SIPR is the Secret Internet Protocol Router Network for secret or classified information.
What encryption does windows remote desktop use?
Remote Desktop uses 128 bit encyption by default, but other encyptions can be configured for this program.
TCP/IP: Transmission Control Protocol(TCP) and Internet Protocol (IP) .
TCP -> As the name suggests it transfers the data from one system to the other IP -> It takes the data in Packets form and delivers them to the specified destination through the IP address provided (to the specified node).
Annapurna.
IP is essentially the data being sent with a nametag that is the destination.
TCP makes sure the IP data arrives intact. If not it will resend the data.

- IP - is responsible for moving packet of data from node to node. IP forwards each packet based on a four byte destination address (the IP number). The Internet authorities assign ranges of numbers to different organizations. The organizations assign groups of their numbers to departments. IP operates on gateway machines that move data from department to organization to region and then around the world.
- TCP - is responsible for verifying the correct delivery of data from client to server. Data can be lost in the intermediate network. TCP adds support to detect errors or lost data and to trigger retransmission until the data is correctly and completely received.
How can you make a telecommunication management network's based element management software EMS?
Dhyan offers Dhyan Network Management Systems (DNMS) and Dhyan Network Management Test Suite (DNTS). Both these technologies are aimed at helping customers get their management systems such as the Network/Element Management System to the market place quickly and in a cost effective manner.
DNMS consists of pre-built EMS/NMS components addressing the generic topology and FCAPS functionality. These components are reusable, open systems based (where possible) and use the state of art technologies to ensure that the systems developed using these components are scalable and customizable.
DNTS technology is designed to help automate regression testing. DNTS is based on third party tools such as Mercury and WATIR to regression test Windows and Web GUI application. http://dhyanit.com/solutions/telecom/element-management-system-technology.htm [url]http://dhyanit.com/solutions/telecom/element-management-system-technology.htm[url]
What is the full DNS name for a particular computer called?
It is called as an FQDN and is read as "FULLY QUALIFIED DOMAIN NAME" , wherein it is in the format:
YourComputerName.YourdomainName
and is Unique in a Domain.
route
In creating a home network do you need a WAN connection?
I am pretty sure that a WAN connection would not be needed for a home network. A WAN is a Wide-Area Network. A WAN would be used to connect to your business computer from home. A LAN is a Local-Area Network. It should be sufficient if the network is simply for sharing files or printers, etc.
After running cmd where is the Mac address?
After running cmd, you can check the MAC (Physical Address) address by using the command ipconfig /all.
Which option is a valid configuration line for enabling access list 102 on a vty line?
router(config-line)#access-class 102 in
What is the Mac address of the DNS server?
login to DNS server
Click start->click run-> type cmd
type IPCONFIG /all
this will give you MAC address of server
Network evaluation worksheet for hands on project 2-1?
for the filename for each abstract when that document was last update. what was the revision date of the most recent standard beginning with 802.3? what do you suppose this standard would be updated frequently?
Find out another pc's subnet mask?
If the other PC is on the same LAN segment then it will have the same subnet mask as yours. A subnet mask is the same for all subnets within a network so that will be the same as well. For other networks it isn't important to know what their subnet is. You could always ask the other user to find out that information if you needed to know.
What are instances in which a computer would use DNS besides ping?
Any time the computer uses a domain name! Ping is used in networking classes as an example. Here are some examples:
- You send an email to somebody@someserver.com. DNS needs to resolve the server name someserver.com.
- In your browser, you type wiki.answers.com. DNS needs to resolve the host name wiki.answers.com.
- You access FTP site ftp://ftp.someftpserver.com. DNS needs to resolve the host name ftp.someftpserver.com.
- Your MSN Messenger contacts the Microsoft servers - perhaps a host name such as msn.com. In all those cases, a hostname is provided by the user, or it is already programmed into some software. To actually communicate, the corresponding IP address must be found.
How do you find IP address of person sending forged emails or Phishing?
It's a fairly easy process in itself, but knowing what to do with the IP is the hard part. And as a sidenote, hacking without a licence to do so is illegal and is grounds for your ISP (Internet Service Provider) to kick you off.
