Their are different types of usb ports. The oldest one is USB1, then comes USB2 which is now mostly used and just out is USB3 but that isn't used by a lot of people at this moment.

Type A and Type B refer to a type of plug on the end of a USB Cable.

USB 2.0 and 3.0 are protocol shifts, 3.0 has some additional hardware behind the cables and 1.0 and 2.0 are identical cable wise. 3.0 is backwards compatible with 1.0 and 2.0.

A serial port is a type of port which sends and receives data one bit at a time, as opposed to parallel ports which can send and receive in multiple streams. A COM port is a type of serial port. At one time it was the most common type of serial port, but USB has supplanted its role. It is becoming increasingly rare for modern PC's to include the old-style COM ports.

The number of ports on a computer depends on the type of computer it is. The type of ports they have--for example USB, headphone, or HDMI--also varies greatly from computer to computer.


You cannot ping specific ports as they are not designed to respond to this type of protocol. Each port can be checked for an open or close state.


Parallel ports typically have 25 or 36 pin ports. Serial ports, by contrast, have only 9 pins. Both type of ports have two rows of pins.

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 really depends on your router. But usually, you can open up Command prompt, type IpConfig, and then look for something that says Ipv4 address. Then go into your internet browser, type 192.168.0.1, find something that says "Port Forwarding" or "Port Opening". Then add a new one. Type a name for it, in the port spots, put the ports you want open, in the address spot, put your Ipv4 address. Bam. The port should be open.


usually sensor or digitized voltages on the inputs. if the port is parallel port, the input doesn't have to be serialized first. Output ports usually converted back to analog for some control application via D/A converters


If you're having problems connecting, make sure you've got the correct Router ports opened or triggered, both for the PS3 & PSN, and the specific MW2 ports as well.ROUTER NAT AND UPnP MODES - ENABLED*Note: Make sure to enable these TCP/UDP ports in BOTH directions (i.e, for Routers that have TCP, UDP, and Both for settings, set them to Both. If your Router doesn't have that type of setting, set the Port to either TCP or UDP as indicated, and enable the pass-through in both directions (full duplex))TCP Ports: 10070 - 10080 UDP Ports: 10070 Voice Chat: UDP 6000-7000, 10070 (for headset operation) Remote Play via Access Point: TCP 9293PLAYSTATION Network: TCP Ports: 80, 443, 5223 UDP Ports: 3478, 3479, 3658Call of Duty - MW2 Ports:TCP 27014-27050 UDP 1500, 3005, 3101, 27000-27030, 28960It's easier to use Port Range Forwarding or Triggering instead of Single Port Forwarding. In those cases where there isn't a range but only a single port listed, your range is the same port, e.g., Range 5223-5223 for Port 5223. Port Triggering is also preferable to Port Forwarding, since Triggering relies on the game or application in question to trigger the Port request when necessary to the Router. Static Port Forwarding setups keep your Ports open as long as they are enabled in the Router setting, and as such are more vulnerable. Trigger Ports are only open as long as the game or application needs them to be open.

A CD :) I know that is not the answer you are looking for. When looking at the notebook does it have ANY ports? Does it have a USB port? Does it have RJ 11, RJ 45 or serial ports? (If you do not know what these look like just type the port names i have listed in your Google browser and search the images category... You will see pictures of what the ports look like). Once you know what ports you have you can figure out what device you can use to up load data. You just buy an external harddrive/memory unit that has the same connection/connector. If you only have an AC port and a CD drive your options are... A CD.


It's almost always a serial port of some kind, but might be an old RS-232 type serial port, a PS/2 serial port, or a Universal Serial Bus port depending on the mouse in question. It could even be Bluetooth (which is still a serial protocol).


For the default Minecraft port, the port is 25565 - however if you wish to have more than one servers running at once, you would have to select a new port, and you'd have to type your IP and at the end of that, add :25564 if you put 25564 as the port. (Include the colon!) I hope this answered your question!

Depends on the type of hub you're talking about. A USB expansion hub for example would allow for additional USB ports.


There are four types of ports used for monitor, the most common is a 15 pin D-sub VGA port. Next most common is a DVI adapter. HDMI is a newer type. CGA is an old style that used a 9 pin d-sub.


It really depends on the type of motherboard and esata port. some computers can have a esata port compatible with usb 2.0. how you would know if your esata port is compatible with usb 2.0 is, it will have the actual usb logo (thing that looks like 3 wires coming from one wire)


Parallel port devices are those devices which are connected to the computer via parallel ports. An example is Printer which is connected to the parallel port LPTx (Line Printer Terminal) eg: LPT1, LPT2, LPT3. Parallel ports were originally developed by IBM as a way to connect a printer to your PC. When a PC sends data to a printer or other device using a parallel port, it sends 8 bits of data (1 byte) at a time. These 8 bits are transmitted parallel to each other, as opposed to the same eight bits being transmitted serially (all in a single row) through a serial port. The standard parallel port is capable of sending 50 to 100 kilobytes of data per second.Answer-- A parallel port is a type of interface found on computers (personal and otherwise) for connecting various peripherals. It is also known as a printer port or Centronics port. The IEEE 1284 standard defines the bi-directional version of the port.
