Computer Networking

Parent Category: Computers
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 we talking networking on routers here or computers? If we are  talking about routers its a matter of port management with the  priority of each service. If we are talking computer level then it  goes back to the level in the FIFFO levels if I remember correctly.  For me it was 23 years ago...
Port 123456 does not exist. To open port 50001 you need to change settings for your port routing tables. Without knowing the exact model of your router it's virtually impossible to help you.
Follow these steps to start the Express Setup program.    1. Verify that no devices are connected to the switch.    2. Press and hold the Mode button, as shown in Figure 1, until the  four LEDs next to the Mode button turn green.    This takes approximately 2 seconds.    Note:...

I think you need to research about DNS. Each Domain name services provider will operate and maintain their own DNS systems. We also have INTERNIC (Internet Network Information Center), and they will have responsibility for manage all domain names and DNS servers. Each DNS have capacities to query...
go down the the little arrow in the bottom right corner, click on  it. There should be a blue symbol with a weird white symbol on it.  make sure the device you are trying to connect to is visible. click  somthing like: find bluetooth devices. when you find the device you  are trying to connect...

The difference is that serial transmissions only use 2 wires for transmitting and receiving data, and only 1 for sending or receiving, and can only send one bit at a time.   Parallel cables use several wires for data transmission and is much faster than serial thus 8 or more wires are carrying...
It appears as though you have the two concepts reversed; if you are using flow control than you are using a reliable delivery method - these are at layer 4 of the OSI model, which is TCP for reliable delivery. TCP provides flow control. UDP would be used for speed, when you do not need reliable...
    Usually wireless routers have also lan ports. Use one of ports in router which directly connected to the modem (internet), and connect it in wlan port of the second router. It should work.

All collisions are errors. If it gets bad enough, I would get a  network admin to check it out. On well designed networks there  should be little to none.
Typically you would need a gateway for this purpose, because the protocols are very different. In my HP server, for example, I have two NIC cards; one of the NICs connects to a Token Ring network and the other connects to an Ethernet network. The software in the HP server (gateway) manages the...
The reason RIP is called a distance-vector algorithm is because of the way it determines the "best path" from one route to another. This is accomplished by something called a "cost metric", meaning that the "cost" of a route determines whether a path is a better path than some other route. A path...
Yes, they can. There are plenty adapters for USB ports as well as PCI, PCIe.
make some words in converse order.
Precisely Timed Signal Transmission in Neocortical Networks with  Reliable transmission using temporal phase coded optical signals  with ... to the existing WDM network for optical steganography  transmission.
It is established after the 3-way handshake is complete and the channel is open between a sender and a receiver.
The DB25 connector on the rear of a PC is used (if it has pins) to connect a printer or (if it has sockets) to connect a modem.
There are a few common ones. RIP, EIGRP, and OSPF are just some.  They just exchange what networks are available.
DHCP is responsible for IP addresses for requesting clients.
No, this is not a wireless printer. If you want, you can wire it  into your Ethernet network and then it might work as a wireless  printer if the Ethernet connects to a WiFi router.
They are able to talk through a connection. That connection needs  to be present otherwise the communication will not happen.
Go to settings, go to controls, on the left there's a little icon for each color, you can choose a special power there (for that color).
A difference is that they have different speed and how can it go
1.Sync. ckts all f/fs are clocked by single clock. Async. ckts o/p of f/f becomes clk for next f/f. 2. Sync ckts are fast. Async ckts are slow. 3.Sync.ckts are easy to design. Async.ckts are difficult to design.
Of course, you can. That's why they are both N type, because they can work with each other.
  == Answer ==   features? Well, the "features" of a true standard 56k modem are that it accepts and sends information in bits and packages through a phone line. DSL and Cable modems are different. They actually convert data back and forth for a higher stream range. I suggest you goto...
Lets say you have 1 outlet but you want to connect yout xbox and your ps3 to the same outlet and not have to switch them out. You will need 2 cat5 cables you will need a wired routuer (you can find one at your local staples or office max) and 3 cat5 cables (for 2 devices needing internet). Whatever...
coaxial is useful in the fact that not only is it used by your  cable boxes to recieve tv channels but it also can be used at the  same time with a modem to receive an internet connection from your  isp!
40 meters inside of the building max, and about 140 meters on open space also maximum.
peer-to-peer (P2P) network
  System support of wide area application
Per segment, the limit is 100 meters.
The three layers that I could think of are User interface, Client  side, and server side.
With a static IP address you have to manually configure each workstation, by hand. Doing so can lead to duplication errors because you mistyped an address that is already in use. You might also get the other settings wrong, such as the default gateway, DNS servers, etc.With DHCP you can more easily...
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...
Metropolitan Area Network, commonly referred as MAN, is optimized  for a larger geographical area than a LAN, ranging from several  blocks of buildings to entire cities. MANs can also depend on  communications channels of moderate-to-high data rates. A MAN might  be owned and operated by a...
That printer must have a wireless connectivity system built-in such  as bluetooth or wi-fi.   To print the item you want. You just need to open the item in your  cell-phone. And then, in the options menu, select 'print' or 'print  via <name>'. You need to do all this keeping the printer...
Connect the printer to a network computer that is connected via a  wireless router. If that doesn't work, use the built in WiFi  connection and tell the computer to look for it and add it is a  separate printer, then set it as the default printer.
A router running a classless routing protocol (Such as OSPF) will send the subnet mask in its route updates to its neighboring routers.
  Go to the Software Downloads section of the Microsoft Hardware  website.   Select Gaming as the product type.   Select Xbox 360 Wireless Controller for Windows as the product  (this is the software for the wireless gaming receiver).  
The subnet mask is used for this purpose; it divides the IP address into two parts, the network id, and the host id.
With an ethernet cable. (male)
Is the layer that provides data routing paths for network  communication. Data is transferred in the form of packets via  logical network paths in an ordered format controlled by the  network layer.

An analog signal is a continuous signal that contains time-varying  quantities. Unlike a digital signal, which has a discrete value at  each sampling point, an analog signal has constant fluctuations.  netonplus.com
The IP address and the subnet mask are required in layer 3 for routing purposes.
To connect your Sony VAIO laptop to a d-link router, connect  wirelessly or use an ethernet cable.
Use security settings for your wireless network, such as SSID hiding, and wireless encryption. It's better if you use WPA AES at least, but WPA-PSK2 AES is better. You can use also MAC filter. But if you have WPA-PSK2 AES you do not need to because it's almost impossible to crack the encryption.
there is 5 catgory cat 1 thru 5 cat1 is called rj11 its for phone lines only, cat 2 is for digital telephones and low speed networks. cat3 is for eathernet cat 4 is for ibm token ring network standard and CAT5 the most known of is for high speed internet with a signalling rate of 100MBps
Bandwidth is the range of frequencies occupied by the signal.
An "ip address" is a complete source or destination address that has a network id portion and a client or host portion. The network id is just a piece of the IP address. So, a public ip is an IP address that can be routed, whereas the network id is just a part of the public ip. They aren't...

A faulty power supply does not supply any power at all to a  computer or supplies incorrect voltages. Most of the time faulty  power supplies are not serviceable and require replacement.
No, this is a common misconception. The application layer is the interface between programs (applications) and the network layers.
HTTP - Hypertext Terminal Protocol
The number of systems connected in a LAN at one time is the number  of devices on your network.
apache web server is a webserver. tomcat is a servlet container.
Back in 1996 the guys over at The Internet Engineering Task Force  (IETF) had to decide what range of IPv4 addresses they could give  away for internal use, meaning that these IP addresses would be  assigned only to devices in closed networks and would not be  available on the public internet. ...
Load balance is a high-availability (HA) scheme, where the service calls direct to one of many service providers, in this case a Message Queue manager, such that it is likely that one is available and ready for access. Fault-tolerance (FT) is about what happens when one of the MQ managers dies...
Ip address play a key role in the networked computers to identify the computers
PHP Vs. ASP.NET- What Serves Website Application Development  Better?
No, you cannot. LAN ports are of type RJ45, when telephone port is RJ11. Basically it means that they have not only different size but also different number of wires.
It depends on model. Some models can save some data without reloading, some can't. Thus you can have partially configured router or not configured at all. But reloading is not going to damage your router.
The TCP/IP Stack is the complete set of internet protocols that are  part of the TCP/IP bundle/suite. They include HTTP, FTP, SMTP and  P2P.
The topology that is chosen depends on a number of factors, including: cost/budgetlength of the network scalability and future expansion plansInfrastructure and current cabling requirementsProtocols used
, the DHCP relay agent is now available under the Network Policy Server. When installing this role, select a role service "Routing and Remote Access" to be installed. The rest is the same like in Windows Server 2003 - just configure it using RRAS administrative console.
Computers that don't have a wireless Internet connection use  ethernet.
In the 8086/8088 the physical address and logical address have the same importance, because they both relate to the address of the operand. It is true that the offset (logical) address is added to the segment address to determine the physical address, but the limitations of the architecture of the...
One uses the airwaves, a wireless router sends a signal. The other needs a cable from the router plunged into a port on the PC.
