A CONTROL is a standard used for comparison
Phosphorus standard is also known as black phosphorus. It has relatively few uses and is pretty cheap.
In order for a substance to be a primary standard it must be able to dissolve in water. Since iodine is unable to do this it cannot be used as a primary standard
Yes. But you need an ISP (Internet Service Provider) and an IP (Internet Protocol) address.
voice over IP
No. The internet backbone is much faster, it is the primary lines between major cities, countries and continents that handle all the traffic from thousands of standard broadband connections.
RJ-11 is a standard telephone (non voice over IP)
People usually complaint about slow speeds. There are people with 300Mbps connections and some with 300kbps. The average internet speed is 5.6 Mbps.
Depending on where you live, internet phones can sometimes have bad connections. This isn't something you ever really have to worry about with a standard line. If you have good internet connectivity, an internet phone should also get a good signal and be just as reliable. Although, if your network goes down for some reason, you will be without a phone.
Dial-Up Internet: A dial-up Internet connection is the most basic and therefore the slowest type of Internet connection that you can get. Connection rates for dial-up modems tend to fall between 2,400 bps & 56,000 bps, which is incredibly slow for today's high speed Internet and applications. Dial-up modems are attached internally or externally to a given computer, and then connected using a standard telephone cable. All in all, dial-up Internet connections are outdated and representative of an older and more basic Internet. ISDN: ISDN (Integrated Services Digital Network) Internet connections are a type of digital telephone connection. ISDN connections straddle the line between basic narrowband Internet connections and more advanced broadband Internet connections due to the fact that Basic Rate Interface (BRI) ISDN connections transmit data right around the broadband cutoff at 100 Kbps. Although a better Internet connection option than dial-up, ISDN connections are still more or less outdated. Digital Cable Broadband: Cable broadband Internet connections are the most common type of broadband service. Connecting to the Internet via your cable television signal, cable broadband Internet connections offer data transfer rates of approximately 1.5 Mbps, far exceeding those offered by either dial-up or ISDN connection types. DSL: Digital Subscriber Line Internet connections are the second most common type of broadband service offering data transfer speeds similar to those of cable broadband (_1.5 Mbps). DSL services connect to the Internet via copper telephone wires. The difference between DSL and dial-up / ISDN is that a DSL Internet connection uses a high speed dedicated circuit filtering out standard phone calls and Internet signals. WI-FI: Wireless Fidelity Internet Connections are currently the hot commodity in high speed connectivity. They boast similar transfer speeds as digital cable and DSL broadband, but they don't require any type of physical connection in order to transmit/receive a signal. T-Carrier Broadband: T-Carrier Internet connections are some of the fastest available in the world and are generally reserved for use by large businesses and universities. T1 and T3 Internet connections are the most common T-Carrier types, and can cost as much as $800 and $15,000 per month respectively. T-1 lines boast speeds of 1.54 Mbps whilst T3 lines boast astounding speeds of around 45 Mbps. OC24: An OC24 (Optical Carrier level 24) Internet connection is a fiber optic connection capable of transferring data at a mind-boggling rate of 1.244 Gbps. This is pretty much the fastest Internet connection that you can get and generally serves as the backbone of various NAPS (Network Access Points).
Ethernet router One, if you want to share an Internet connection Telephone cables One for each computer on your network (use a standard telephone cable to plug each computer into a phone jack)
RJ45 Telecommunications - a connector standard for telephone cables, RJ45 cables are also used as a connector for a computer network by way of connecting to the internet.
IP is "Internet Protocol" a standard for sending information/data over the Internet. VO stands for "Voice Over". Thus VOIP is a method for sending speech (as data) over the Internet rather than using the telephone system to do this.
ranges from 1 to 15,000user connections.
POTS - the "plain old telephone system" - can be used to connect a computer to the Internet. Basically, you will need:Access to the telephone systemA computerA modemA contract with an ISP (Internet Service Provider), that allows you to access the InternetSome software. Standard software, available on most modern computers, will work; I just mention this for completeness sake.
