Broadcasting refers to the distribution of data or information to multiple recipients or devices simultaneously. A network connection device that relies on broadcasting is a router. Conversely, a switch is a device that does not rely on broadcasting, but instead uses a more efficient method of directing data traffic to specific devices on a network.
Broadcasting is when a packet is sent to all hosts, or all hosts on a subnet. When a broadcast packet is sent through a typical ethernet switch, all port lights will flicker as that packet is forwarded out every port. Other packets are inspected for their intended destination and then forwarded out the correct port.
Two very necessary and prevalent protocols, DHCP and ARP, rely on broadcasting. This means a typical ethernet router/gateway device relies on broadcasts. A device that does not rely on broadcasts is an ethernet NIC.

GPS would be the most helpful. It can tell the hikers where they are and where they need to go. Also, since it relies on satellites, the device will never be out of range as cell phones or radios might be.
Short answer: neither Long answer: Science and technology are interdependent of each other. Science relies on technology to progress, and technology relies on science to do the same.

I believe that allot of times technology does keep its promised but some of it relies on your standards
Bluetooth technology relies on a PAN (personal area network)
A "client".

Yes, you can have a LAN (Local area network) party when the PlayStation Network PSN) is down. A LAN connection does not require Internet access, which is what the PSN relies on. As long as you have an ethernet cord and two or more PlayStation 3 systems, a LAN party is possible.

real-world data, a device that can run the software, power for the device, etc.
The wired or wireless means of connecting a computer to the internet is called networking. The wired network uses cables while the wireless one relies on signal transmissions without cables.

A compass relies on Earth's magnetism to stay pointed north.
A wireless adapter that uses a universal serial bus (USB) connection gives a business the flexibility to make any computer or laptop a part of the wireless network. A wireless USB network adapter relies on a limited amount of power when it is attached to a laptop or other device. This can sometimes restrict the range of the adapter. One way to extend the range is to change the antenna on the unit. A wireless USB network adapter uses some type of antenna to send and receive signals. This antenna can often be removed and replaced from the unit. The most common type of antenna on a wireless USB network adapter is an omnidirectional antenna that receives signals in all directions. A much stronger connection can be maintained across a longer distance with a directional antenna that focuses on signals coming from a specific location. These antennas are inexpensive and very effective in an office environment. Unfortunately, this will not work with a wireless USB network adapter that contains an integrated fractal antenna that cannot be replaced.
The difference between a router and a switch has to do with the layers of the OSI model that they reside in. A switch is a layer 2 device, which means it relies on the MAC (physical) address for switching packets. A router is a layer 3 device, using the network (logical) address. A router also can forward packets to another network; a switch does not do that. In addition, a switch forwards all broadcast packets whereas a router does not forward broadcast packets.
Yes as long as you stay connected. It's relies on an internet connection for both devices
