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 aretalking about routers its a matter of port management with thepriority of each service. If we are talking computer level then itgoes back to the level in the FIFFO levels if I remember correctly.For me it was 23 years ago when I was in...
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 thefour LEDs next to the Mode button turn green. This takes approximately 2 seconds. Note: This only works on switches...
For master degree program you must have to passed and certifiedyourself for getting certification exams like Microsoft, Apple,CompTIA, VMware, SISCO etc. I give you the direct link access tosite where you can easily get all exam dumps material in a verycheap rates and started your preparation with...
Optical fiber cables transmit light from one end to the other. The data is encoded into this light beam and travels down the fiber in this light. Obviously you need optical sensors at each end to get the information in and out.
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 onit. 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. clicksomthing like: find bluetooth devices. when you find the device youare trying to connect to, click on...
Check the wireless network properties, one of settings is security for wireless networks. If you want a definite answer you need to show your router's model.
It's better to start from the router. But over it does not matter. When you hook up the adapter first, it might take just a little bit longer to connect to the network.

Doing that might give you interference with your data transfer rate.
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 data ...
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...
\nUsually 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.
just donload an app named app data and open your bluetooth selectitem it atomatically archeved the file then slick send it can besend.......................I think it can be...USEFUL
Transport layer -->TCP,UDP
10BaseT has transmission rate about 10 Mbps and 802.11b is about 11 Mbps. Usually wire connections are closer to their theoretical limits than their wireless counterparts.
You need to find out which adapter you have. After that, check the laptop manufacture website for appropriate drivers.
A C prompt is when you go to the Start Menu and go to Run or thesearch bar and enter Command. From there, a black screen will popup with the drive letter and the current folder/path.
Many people are affected by lags when accessing the Internet.However, you can reduce how much you are affected by this bychanging a few things.

A switch is a device that connects clients together in a local area network. A bus is a network topology, which describes the wiring used to connect clients together. A bus is not a device, and a switch is a device.
All collisions are errors. If it gets bad enough, I would get anetwork admin to check it out. On well designed networks thereshould 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.
You can use as many as you want. But if you have a 54mb wireless router, and one devise is using the 54mb then there is none left for the others. One devise will never use this much, just trying to get you to understand the Idea. Basically you could run 20 computers and if they are only...

WPA-PSK is a type of encryption which must be used if you have choose between WEP and WPA-PSK. If you have an option to use WPA-PSK2 to use it because it's even better. PS: The problem with WEP is that it takes about 5 minutes to hack it. For WPA-PSK with password of at least 8 symbols it might...
You use can. You need to make sure that the device is on. After open Device manager and press "Scan for hardware changes" or something like that (it depends on OS). If the device is working fine your OS will automatically install drivers for the device or you will see a device which was not...
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 itinto your Ethernet network and then it might work as a wirelessprinter if the Ethernet connects to a WiFi router.
They are able to talk through a connection. That connection needsto 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).
It depends on router. Almost all new models allow to connect external drives directly, and make it available for all network.
If your phone is capable of connecting to your router, then the answer is yes. You can use it to get free internet on your phone. You just need make sure that your phone gets internet through wireless internet not from phone service provider (Verizon and so on).
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...
\nIf you have encrypted network, it's not easy and even experinced users cannot do that. For non-ecrypted network it's really easy to do using special program which is called sniffer. Your password should different from the standard ones.
coaxial is useful in the fact that not only is it used by yourcable boxes to recieve tv channels but it also can be used at thesame time with a modem to receive an internet connection from yourisp!
Coax has a better security protection because it's usually shielded. Also range for Coax is for thinnet about 175 meters for thicknet about 400 meters.
40 meters inside of the building max, and about 140 meters on open space also maximum.
Yes, you can. You assign for both ip addresses from the same network (manually). And using Add hardware wizard add the printer. It might very tricky to do.
Actually, an IDS does not sit on one particular layer. It has to examine packets for protocols, how they are being transported, number of packets transmitted, spoofing information, and application layer information. In general terms, Intrusion detection system and Intrusion prevention system is a...

10 mbps ethernet uses Manchester encoding where each symbol is represented by 2 bit sequence. Hence the bits/symbol is 2. Since data rate = bits/symbol x symbol/seconds, symbols/seconds = baud rate = 5 mega baud
Per segment, the limit is 100 meters.
The three layers that I could think of are User interface, Clientside, 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...
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 optimizedfor a larger geographical area than a LAN, ranging from severalblocks of buildings to entire cities. MANs can also depend oncommunications channels of moderate-to-high data rates. A MAN mightbe owned and operated by a single...
That printer must have a wireless connectivity system built-in suchas bluetooth or wi-fi. To print the item you want. You just need to open the item in yourcell-phone. And then, in the options menu, select 'print' or 'printvia '. You need to do all this keeping the printer onand then following the...
Connect the printer to a network computer that is connected via awireless router. If that doesn't work, use the built in WiFiconnection and tell the computer to look for it and add it is aseparate 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 Hardwarewebsite. 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 networkcommunication. Data is transferred in the form of packets vialogical network paths in an ordered format controlled by thenetwork layer.

This is an IP address. IP stands for "Internet Protocol". These types of addresses are the real ones used on the internet. The types of addresses we are used to typing (e.g. are translated internally by another computer into this numeric address, that is actually used to go to a...
An analog signal is a continuous signal that contains time-varyingquantities. Unlike a digital signal, which has a discrete value ateach sampling point, an analog signal has constant
The IP address and the subnet mask are required in layer 3 for routing purposes.
Once you buy your laptop, it is yours, you do not need to pay any fee for it in itself. However, if you choose to get internet, you will need to pay a monthly fee for the Internet connection.
To connect your Sony VAIO laptop to a d-link router, connectwirelessly 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
The purpose of Layer 4 port assignment is to identify the processes or services that are communicating within the end devices.
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...
Well Pokemoncrater will never come back because it crashed but some one will make a
You are not supposed to open that file on your desktop. VLC player opens it because it uses the same extension for different file. Anyway, if you want to use the driver (firmware) you need to log in your router and use "Update firmware" field. It will ask you to show destination of the new firmware...
