† T† 1. All types of computers and mobile devices serve as sending and receiving devices in a communications system.

† F† 2. Files on an intranet also are accessible from the Internet.

† T †3. Disadvantages of BANs include data validity and security.

† T †4. A peer-to-peer (P2P) network typically connects fewer than 10 computers.

† T† 5. Voice and video calling require large amounts of bandwidth.

† F† 6. UWB requires line-of-sight transmission, so its technology is not as widespread as IrDA.

† T† 7. For successful communications with NFC devices, the devices or objects must touch or be placed within an inch or two of each other.

† T† 8. DSL transmits on existing standard copper phone wiring.

† F† 9. Large corporations, phone networks, the Internet, and other networks with large amounts of traffic use DSL.

† T† 10. A broadband modem is a communications device that converts digital signals to analog signals and analog signals to digital signals, so that data can travel along an analog phone line.

† T† 11. Although some routers may be able to connect more than 200 wired and/or wireless computers and mobile devices, the performance of the router may decline as you add connections.

† T† 12. With satellite Internet connections, uplink transmissions usually are slower than downlink transmissions.

//a. standard that outlines characteristics of how two devices communicate on a network

//b.††††††† guidelines that specify the way computers access the medium to which they are connected, the type(s) of medium used, the speeds used on different types of networks, and the type(s) of physical cable and/or the wireless technology used

//j.†††††††† network standard that defines how high-speed cellular transmissions use broadcast radio to transmit data for mobile communications

Problem Solving:

1.       One issues may be that your computer doesnít have Bluetooth compatibilities. Most desktops donít but many laptops do. If thatís the case then the Bluetooth system may be off on your computer. If so just turn it back on. If not then try resetting both devices.

2.       I would try turning the WIFI capabilities on the laptop of then back on. If that doesnít work then turn the laptop off and on.

3.       If two devices are connected to one Bluetooth system it usually connects to the closest device or the device with the strongest signal. Either thatís the issue or the Bluetooth capabilities are turned off on the device.

4.       One thing that could be an issue is there is a network virus slowing down your speed or the signal is being interrupted somehow causing a slower than usually speed.

5.       Not many people know this but when a microwave is running the frequency interrupts the WIFI signals. Another reason could be that other people are using the WIFI and you are in a location where the signal is already low so when the bandwidth is split up you lose out on the connection.

Internet Research:

1.       A) Tumblr & Blogger: Itís the same to set up a blogging account as most other social media sites. You must input your name, DOB, E-mail address, and usually a username. These sites allow for the free usage and able to create your own blog. There are no real storage limitations as to the amount of posts you can make but there are limitations to the size of a file that can be uploaded. You can customize anything to do with text and you can even change backgrounds. I donít think you can advertise anything specifically for yourself but the sites themselves allow for advertisements. If I set up a blog I would mostly talk about sports and then the odd political issues. You canít assign your own domain name you just get an extension of the base domain name.

B) Wikipedia & WikiLeaks: WikiLeaks featured Ė Amazon Atlas, ICE Patrol, Hilary Clinton Email Archive, Spy Files: Russia. Wikipedia Ė Rhode Island Tercentenary half dollar. These wikis are publicly funded with ads as their source of income. Anyone can edit Wikipedia pages but Iím pretty sure only Admins can edit pages on WikiLeaks.
