What is the advantage of static routing over dynamic routing?
Static routing is used when there are a finite number of routes that never change. This allows you to optimize the table according to its size and provide the fastest routing algorithm possible.
Dynamic routing is used when the number of routes change on a regular basis either in size or because some links change speed. These routing tables need to be reorganized on a regular basis and that takes time. Even though it may not take much time to reorganize the table, you must make sure not to affect any routing that involves quality of service constraints.
What is logical port blocking?
It is a number used in a certain format simply to let network aware applications differ one service to the other. Common syntax is : url:logical port number.
example :
http://one.two.com:80
80 - http service
Mapped and/or shared folders on a network allow users to collaborate and share information by modifying the documents in the folders or by putting documents in the folder that is shared without realizing that the folder may not be on their machine, but it looks as though it is.
Where can one buy a cable modem wireless router?
Their are many retailers where you can purchase a wireless DSL modem but I recommend going on Amazon and browsing through your options. I would recommend a netgear modem.
Where is the location of dns server?
The exact location of hardware providing an internet service is the private information of the owner of the service.
Reasonably an owner would not want the servers' location known in case it became the subject of physical attack.
The owner may reveal the location to authorities on production of court documents but I can not see why they need to do so otherwise.
If you have a problem with Google or its services, I suggest you write to them using their published complaints procedures.
The link below its to an article on the Google DNS service.
What device is used to send data between two networks?
If the message is going between two different networks then it must be routed (this includes different subnets of the same network as well). Routing is done by a router as the device.
What is the transmission speed of coaxial cable?
from what I've seen, there are many different types of coaxial cables and they all have different transmission rates. From the old days, (90's), TV had a transmission rate of about 768kbits/s, which is now irrelevant because there are cables that can go up to 200Mbits/s (According to what I have gathered here)
What is the host id of this IP address of 131.107.2.200?
Since this is a class C network address, the host id is 24, the network id is 201.123.87.0
Which protocol is used specifically to transfer large files?
If you have a file which is too large to email, there are a few applications you may use to transfer. The most common would be to use WinRAR or other zipping program. Or you could upload via FTP (file transfer protocol) in order to share it with others.
How can i reset Pronet PN-54WRT wireless router?
It should have a special little bottom to reset. If you press and hold for 5-35 seconds depending on particular router it will reset all settings to manufacture ones. If you have manual for the router, it's a good time to read it.
What statement describes the function of the Address Resolution Protocol?
An ñARPî or Address Resolution Protocol is a protocol that is used in telecommunications for a resolution of network layer addresses into link layer addresses, which is vital in multiple access networks. It is also the name of the program that is used when manipulating addresses in most operating systems. The Address Resolution Protocol is used to convert an IP address to a physical address such as an Ethernet Address.
What is a administrator account?
Answer
In Windows NT/2000/XP/Vista, an administrator account is an account that is permitted to install software and upgrades, change file permissions, and create new users.
Answer
Account for the person who is fully responsible for network security and every other computer user accounts are under his administration.
What is the name of the file that keeps associations between computer names and IP?
The name of the file is either 'Temp' or 'Locals'. These files are temporary in nature and keep the association between computer names and IP addresses. Since IP settings and computer names change often, the file simply reflects the latest settings when saved.
A computer when connected to the internet is considered to be on a network?

How much does a Vonage Router usually cost to buy?
A Vonage brand router usually cost around 48.99 but the price may vary depending on the retailer of choice. A router allows a person to access the internet and if a person is interested in learning more about routers or purchasing one they may call their local internet provider.
Usually the systems will be assigned an APIPA address in the range 169.254.x.y in order to use resources in their own LAN.
The APIPA configuration can also default to static IP addresses if necessary.
If APIPA is not being used then the only way to use the network is to manually assign a static IP address and all of the required settings.
What are two protocols that support email communication in a network?
SMTP (simple transfer mail protocol) which is used as the outgoing mail server and it uses port number :25
POP3 (Post Office Protocol 3) is the most recent version of a standard protocol for receiving e-mail. POP3 is a client/server protocol in which e-mail is received and held for you by your Internet server and it uses port 110
What do switches implement to eliminate a broadcast storm?
In order to prevent broadcast storms and other side effects of looping, Digital Equipment Corporation created the Spanning Tree Protocol (STP).
Yes, you can add printers to your Netbook. As long as you Netbook have USB ( nearly all the Netbooks have it. One can connect their Netbooks to the any printers that enables USB drives.
As I am a student, and I am using Intel Atom embedded Netbook and requires to take many printouts as the requirement of my subjects. More importantly, Intel Atom Netbooks are lightweight and easy to take anywhere. Intel Netbooks is much lesser price as compare with Laptop and with a great battery life (approx. to 10- 12 Hrs.).
An Open System is a computing platform that uses Open Source softwares rather than Closed Source/Proprietary softwares.
Closed source software may charge for their software, but might not.
If a development firm releases software for free, but does not release the source code to the public, this is called "Freeware."
Proprietary software generally does not distribute their software for free, and it follows that the owners do not distribute the source code either.
An few examples of proprietary software are Microsoft Windows (Operating system), Microsoft Office (Office Software Suite), Nero (CD/DVD Burning Software), and WinRAR (Archiving Tool).
The point of an Open System is to break away from the use of software that you have to pay for. Some people also go a step further and refuse to use software that the owners do not release the source code of.
This principle is especially useful in business, where a company can save a lot of money making their employees use Free and Open Source software rather than paying licensing fees to use one product on multiple machines.
A few examples of Free and Open Source softwares that do the same job as the Proprietary softwares cites above are:
Debian Linux (Operating System), Open Office (Office Software Suite), K3b (CD/DVD Buring Software), PeaZip (Archiving Tool).
How do you make my PC wireless?
If you mean a wireless network connection - you should buy a WiFi adapter (USB or PCI or PCI-e), install it in your computer and then set-up a new network connection.
If you mean wireless as no-cable-power - there is a problem. Desktop computer uses much more power than laptop and no battery can power it for a time longer than few minutes.
