What portion of the IP address 129.219.51.18 represents the network?
It is a class B address (The first three numbers (octet) are between 128 and 191), meaning it has a subnet of 255.255.0.0, thus, 129.219 is the network portion, with 51.18 representing the host portion.

What are the input and output devices available today?
Input and output devices are hardware components that allow a computer to receive and process data, and provide the results of this processing to the user. Some examples of input and output devices available today include:
Input devices: Keyboard, mouse, touchpad, touch screen, microphone, scanner, game controller
Output devices: Monitor, printer, speakers, headphones, projector, touch screen
These devices are available in a range of sizes, designs, and features to meet the needs of different users and applications. Some devices may be specialized for specific tasks, such as gaming or graphic design, while others may be more versatile and suitable for general use.

Difference between SC-ADA and Distributed control system?
SCADA will perform supervisory action over Distributed control system to make sure that every thing is working fine.
How many E1 in 1Fast Ethernet?
The simple answer is: An E1 is 2Mbits/s, FE is up to 100Mbits/s Therefore up to 50 However I suspect the question needs a bit more explanation and context.
Based on the additional info (which I will add to the discussion page) it sounds like you have a problem with DNS (Domain Name Server) which resolves friendly names like wiki.answers.com into IP addresses. It seems likely your client computers have cached the DNS entry for google but can't resolve any other names to IP addresses. I believe this because the client computers can perform new google searches which rules out the possibility that you can just see cached internet content.
Assuming your server is running DNS, which I believe is the default for MS Server 2003, the chances are that making the private address of your server (the IP address of the Server LAN interface) the primary DNS entry for the clients and removing any secondaries will solve your problem.
I would manually configure the TCP/IP settings on one client and see if this solves it. If it does you can go on to change the DHCP settings if you are using DHCP once you know it works.
If your server is not running DNS you will have to either install/enable DNS or edit the firewall on the server to allow it to proxy DNS requests (Port 53 on TCP and ideally UDP) which I believe can be done using SOCKS proxy.
Don't be suprised if your users can't even access google when you go back to work, if I am right about the cause the google DNS cache entry will expire at some point and then your users won't even have access to that.....
How can you use dial up with a laptop that doesn't have a port for it?
you can go to netflix or some company that doesnt have a port for it but wireless internet would be the best if your on the computer 24/7!
Can an airport capable mac computer work with a Netgear wireless router?
Yes, I'm using one right now to answer this question from my kitchen table (my laptop) to my wireless router (family room downstairs where the cable modem is located.)
Given a baud rate of 1200 bauds per second and modulation technique what is the data?
all you need is to know the modulation technique and then you can know how many bits per one symbole then to calculate the data rate = baud rate * bits/symbole
Which organizations publish computer-network standards including ISDN standard?
The United States Telephone Association (USTA)
The International Organization for Standardization(ISO)
The Institute of Electrical and Electronics Engineers (IEEE)
The Internet Engineering Task Force (IETF)
When implementing the recommendations from the AAR and action items from the IP planners should?
Planners should prioritize according to benefits and use as much local resources as possible. It is also recommended to regularly review potential alternatives and improvements.
What is virtual primary network?
I think you would mean Virtual Private Network (VPN), if not then no need to read on.
A VPN is a way of creating a environment where hosts that are not on the same network or lan to be apart of a Logical environment (VPN) as if they are all connected locally. This is good for security reasons, or simply to separate computers from others such as in a business where you want each room on a VPN. I Hope this helps you. If not, please message me.
Bit stuffing is used for various purposes, such as for bringing bit streams that do not necessarily have the same or rationally related bit rates up to a common rate, or to fill buffers or frames. The location of the stuffing bits is communicated to the receiving end of the data link, where these extra bits are removed to return the bit streams to their original bit rates or form. Bit stuffing may be used to synchronize several channels before multiplexing or to rate-match two single channels to each other.
What is difference between Remote Assitance and Remote desktop?
remote desktop allows only one user either local user or expert user., remote desktop assistance allows both the novice and expert.
What is high speed data transmission?
Transmission at faster rates than a given network was first designed for, this may be possible by just upgrading the network interfaces but frequently also requires upgrades to part or all of the network itself.
According to following constellation diagram if bit rate is 6400 bps what is the Baud Rate?
From the given constellation diagram determine whether its ASK, FSK, PSK or n-QAM. Then use the appropriate value of r to get Baud Rate = Bit Rate/r.
How much bandwidth is there in 0.1 micron of spectrum at a wavelength of 1 micron?
delta_f = c * delta_lambda / (lambda*lambda)
where
delta_f is the bandwidth range,
c is the light speed,
delta_lamba is the wavelength range, and
lambda is a certain wavelength.
Therefore,
delta_f = 3*10e8 * 0.1*10e-6 / (10e-6 * 10e-6) = 3*10e13Hz = 30THz
Unable to ping Network printer's IP Address?
You can have tons of reasons for that. If other people can ping it then, you have problems with firewall, you are in a different subnet, or you are in diffrent group. If you have active directory, it's possible that administrator doesn't allow to connect to that printer. Solution for such cases usually are either simple or very comlicated. Try to check setting for a computer wich already connected to that printer (group, subnet, permissions and so on). If you are in a diffrent subnet it can be a problem, it depends on which printer you have. If it's an old model then try to find a free IP address in the same subnet with the printer. Also check firewall settings.
If nobody can connect to the printer or ping it then check cable, try to restart it...
