An ad hoc network connects two or more devices directly without a wireless access point for quick data exchanges or multiplayer gaming. Cordless mice transmit data via infrared radiation or radio signals to a receiver connected to the computer via USB or built-in. Wireless keyboards use either infrared light waves or radio frequencies from 27MHz to 2.4GHz to communicate with devices, with most modern keyboards using 2.4GHz radio signals.

4. Some people confuse wireless access
points with wireless ad hoc networks.
An ad hoc network uses a connection
between two or more
devices without using a wireless access
point: the devices communicate
directly when in range. An ad hoc
network is used in situations such as a
quick data exchange or a multiplayer

13. Cordless or wireless mice transmit data
via infrared radiation or radio . The
receiver is connected to the computer
through a serial or USB port, or can be
built in , Modern non-Bluetooth and non-
Wi-Fi wireless mice use USB receivers.
Some of these can be stored inside the
mouse for safe transport while not in use,
while other, newer mice use newer "nano"
receivers, designed to be small enough to
remain plugged into a laptop during
transport, while still being large enough to
easily remove.

15. Wireless keyboards based on infrared
technology use light waves to transmit
signals to other infrared-enabled
devices. But, in case of radio
frequency technology, a wireless
keyboard communicates using signals
which range from 27 MHz to up to
2.4 GHz. Most wireless keyboards
today work on 2.4 GHz radio
frequency.
