How to reset WI-Fi password?
Question:

I forgot my WI-Fi password and I am trying to reset it someone PLEASE!!!!! help me I ant stress enough how much I need this

Answer:
On the back of your router should either be a reset button or an inlet with enough room for a paper clip or toothpick to fit in. Use one of these to firmly hold down the rest button for 5-30 seconds (depending on manufacturer), then release it. This should reset your router to factory default settings.

If you do not have physical access to the router, then most likely you're trying to penetrate a system you're not supposed to access, and we can't help you.

Direction of Data Flow:

Communication between two devices can be Simplex, half duplex, or full duplex.

Simplex:

In Simplex mode Data flow one side only In this type device A send data to device B but device B not able to send data to device A.

In our daily life we use TV cable connection is an example of simplex data flow.

Half Duplex

In Half Duplex mode Data flow both sides. In this type device  A and device B send data to each other  but when “A” send some data device  “B”  not send data and when device “A” send data device “A” not send data.

In our daily life we see police man use wireless phone/ walky talky is an example of Half Duplex data flow.

Full Duplex

In Half Duplex mode Data flow both sides. In this type device  “A” and device “B” send data & receive data same time.

Mobile phone is an good example of full duplex data flow.
