Basically, yes. It can also be more specific or more complex than this (such as WWANs and VLANs) but the gist of it is:
A network is a group of communication devices which have intercommunication.
A group of computer interconnected via a cable or wireless computers and peripherals that are capable of sharing software and hardware resources between other computers.

By far, the most popular technology for desktop and notebook computer wireless connections is IEEE 802.11
Apple computers can be used with wireless printers. These include MAC desktop computers as well as MAC laptop computers. Wireless printers allow printing without the use of a wire connected to the computer.
Wireless computer connections allow computers to connect to a network and use network resources (or access the internet) without having to connect to a router by Ethernet cable. The advantage of this is mobility. Wireless connections are typically slower than cable so you do sacrifice speed for convenience. It is also easier to connect a large number of computers in a large area (where wires would be impractical to run) more easily. This technology works best in open areas. Also, the farther away from the Wireless Access Point the computer is the slower the throughput (i.e. the connection) will be.
You can't add wireless router to your computer. You can a wireless router to your network. If you do so, it does make your network wireless. In order to use your network wirelessly you need to have wireless adapter for all your computers you want to be connected wireless.
Wireless charging is one upcoming technological advance.
A wireless computer network connects through to the internet without being connected with wires. It gives you a fast and easy connection and is a modern technology.
The wireless portal is powered by the computer, and a signal is shared between the two devices, using infrared, radio or Bluetooth technology.

IEEE 802.11
Every computer that is connected to a local area network or LAN should have an Ethernet card. For wireless networks, computers should have a wireless adapter.
