Computer Networking

Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

Are Open protocols are commonly used to link together proprietary equipment from several vendors?

Yes, open protocols are commonly used to link proprietary equipment from different vendors, as they facilitate interoperability and communication between diverse systems. By adhering to standardized protocols, devices can exchange data and work together seamlessly, regardless of the manufacturer. This approach enhances flexibility and reduces vendor lock-in, allowing users to mix and match equipment according to their needs.

What distance is a Multi-mode fiber optic cable used?

Multi-mode fiber optic cables are typically used for shorter distances, generally ranging from 300 meters to about 2 kilometers, depending on the type of multi-mode fiber and the application. They are commonly utilized in local area networks (LANs), data centers, and for interconnecting equipment within buildings. Their shorter range is due to modal dispersion, which limits the distance data can travel without degradation. For longer distances, single-mode fiber is preferred.

Why is a protocol for a standardized service documented independent of an implementation?

A protocol for a standardized service is documented independently of an implementation to ensure interoperability and consistency across different systems and platforms. This separation allows multiple implementations to adhere to the same set of rules and guidelines, facilitating communication and data exchange. Additionally, having a clear, standardized protocol enables easier updates and maintenance, as changes can be made to implementations without altering the underlying protocol. Ultimately, this promotes innovation while maintaining compatibility among diverse technologies.

What are TCP FIN scans?

TCP FIN scans are a type of network scanning technique used to determine the status of ports on a target system. By sending TCP packets with the FIN (finish) flag set, the scanner can check for responses that indicate whether a port is open, closed, or filtered. If the port is closed, the target typically responds with a RST (reset) packet, while open ports may ignore the FIN packet, making this technique useful for stealthy reconnaissance. This method can help evade detection by firewalls and intrusion detection systems, as it does not conform to standard connection initiation requests.

What is a network environment?

Preface: in wrong category; Nothing to do with cars. It is as term for computer connections, the equipment used, software and hardware. Oversimplified, if all the computers on one office are connected to one printer, that is a network environment. Types of devices, protocols in use, mainframe network interfaces, ISP addresses, network and subnetwork addresses, data center switches, and routers.

Can ping websites but cannot browse?

It was Thanksgiving and I went to my adviser's place. He had a Toshiba laptop with a weird error. None of the browsers could connect to internet. However, if you ping any website using command prompt you do get replies. That means the laptop connects to the internet but not through a browser. I tried various things such as disabling Symantec antivirus, even disabling firewall and trying to run browser as an administrator but to no avail. Finally, before giving up I wanted to try the virgin OS, it was XP in this case. ∞¢§ ¶§• ¶¢¢ºª˚ ©†∆ ˙∆˙∆˚˚˚∆˚∆˚˚˚∆. After that I uninstalled Norton antivirus and then ran this tool to remove the residues. It asked for a restart and Voila. Everything was working fine. The browsers connected to internet without any problem. Since we can't post links here see the related link section for the original post that I found. The issue was with Norton for sure. But what was the issue? The thing is that laptop these days come with a pre-installed version of Norton. If you uninstall that one and install a new version it might conflict with earlier version and cause weird issues in your OS. You need to run Norton Removal tool once you uninstall their product. In short, Norton Sucks. I don't recommend a product which needs a special removal tool. If I were Symantec I would bundle this tool in the un-installation package. Anyways, I hope this will come handy.

Do you need to restart a router to enable port forwarding?

It strictly depends on the model. Most routers have to be restarted in order to enable port forwarding.

How is the application layer protocol telnet similar to http and ftp?

Telnet is similar to HTTP and FTP in that all three use the TCP protocol for connection-oriented

How do you play Windows games on mac without installing windows - is there a download that you can get that makes them compadible - if so what is it and how do i find it?

The basic answer is you can't, at least not with easy 100% compatability.

However, you can try installing WINE on your Mac, which has good support for quite a few games; here is at least one tutorial: (http://davidbaumgold.com/tutorials/wine-mac/). Check out WINE's forum as well to see if your game(s) are well supported. (http://www.winehq.org/). Be warned, however, that this is not a magic solution; it isn't always straightforward to get a game working, you may have to mess with the configuration for a long time, apply various patches and even then expect occasional crashes. Read the instructions for specific games to see what's involved.

There is also a non-free solution, apperently, something called CrossOver games, but I'm sorry, I don't know anything about that.

If you really have to have 100% compatability, I'm afraid you'll have to look into dual booting.

Why wont your linksys router accept the default password when you never set one?

Most routers come with a password built in.

check the documentation (Sometimes it comes with the router printed, sometimes it is a PDF on the CD that came with it), but in my experience, it is usually:

User Name: admin

Password: admin

The first thing to make sure of is that you are connecting to your own linksys router and not a neighbors. Use the direct connection set up to rename your router to something unique and make sure that is the one you are connecting to.

Given class C address with a default subnet mask How many possible subnets and usable hosts if 4 bits were borrowed?

that gives you 16 subnets with 14 usable IPs for hosts that is because one is for subnet and one for broadcas in that subnet

for example: 192.168.1.0/28 - subnet number

192.168.1.15 -broadcast number

usable IPs for hosts - IPs between them that is 14

Can router be used as a server?

Generally, no, unless the router is part of a server based system. A router is a dedicated device to routing packets between networks or subnets. It has no traditional server function such as print or file serving, etc.

How can you get people for networking event?

You can get people there by giving out the benefits and show them that you really care. With this you can increase profits, increase referrals, and increase presence.

In a telecommunications network architecture a protocol is?

A protocol is a set of rules that are standard for a telecommunications network. These rules will outline procedures and controls that are in place for the network.

What are interview questions on computer networking?

A question revolving around computer networking could include asking if someone has ever set up a network. You could also ask if they know how to use a network.
