Compare/contrast common Internet service types Flashcards
Fiber optic def internet
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber.[1][2] The light is a form of carrier wave that is modulated to carry information.[3] Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required.[4] This type of communication can transmit voice, video, and telemetry through local area networks or across long distances.[5]
Optical fiber is used by many telecommunications companies to transmit telephone signals, internet communication, and cable television signals. Researchers at Bell Labs have reached a record bandwidth–distance product of over 100 petabit × kilometers per second using fiber-optic communication.
Cable internet
In telecommunications, cable Internet access, shortened to cable Internet, is a form of broadband internet access which uses the same infrastructure as cable television. Like digital subscriber line and fiber to the premises services, cable Internet access provides network edge connectivity (last mile access) from the Internet service provider to an end user. It is integrated into the cable television infrastructure analogously to DSL which uses the existing telephone network. Cable TV networks and telecommunications networks are the two predominant forms of residential Internet access. Recently, both have seen increased competition from fiber deployments, wireless, mobile networks and satellite internet access.
broadband internet access internet
broadband is the wide-bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast internet connections. The medium can be coaxial cable, optical fiber, wireless Internet (radio), twisted pair, or satellite.
DSL internet
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.
DSL service can be delivered simultaneously with wired telephone service on the same telephone line since DSL uses higher frequency bands for data. On the customer premises, a DSL filter on each non-DSL outlet blocks any high-frequency interference to enable simultaneous use of the voice and DSL services.
The bit rate of consumer DSL services typically ranges from 256 kbit/s to over 100 Mbit/s in the direction to the customer (downstream), depending on DSL technology, line conditions, and service-level implementation. Bit rates of 1 Gbit/s have been reached.[1]

DSL Internet: Slow, but the Most Affordable
Cable Internet: Best With TV Bundles Multiple speed and price ranges
Fiber Internet: Fastest, but Limited Coverage
DSL vs. Cable internet
DSL uses telephone lines and is the slowest option, whereas cable transmits data over copper TV lines, works faster, and carries more bandwidth. DSL is widely available because almost every part of the country has access to phone service, so it’s a great option for people in rural areas who don’t want to choose satellite internet. Cable is ideal if you stream on multiple devices, hop on a lot of video calls, or download large files, while DSL is better if you only check your email every once in a while and casually surf the internet.
Cable vs. Fiber internet
Fiber internet provides a high-bandwidth connection and speeds up to 1 Gbps. Cable speeds can be as fast as fiber, but they slow down during peak use times when all your neighbors get home from work and watch Netflix or a big game. That said, cable covers about 88 percent of the U.S. at an average speed of 10 Mbps to 1 Gbps. Fiber is great for competitive online gamers or someone who wants the fastest speed available and lives in larger cities where it’s available. If you want extremely fast internet, then AT&T Internet is a top contender.
DSL vs. Fiber internet
DSL and fiber are complete opposites when it comes to speeds and coverage. Fiber is new, so it has less coverage than DSL, but fiber expansion projects are under way. DSL usually runs over pre-existing lines, making setup easy. On the other hand, fiber requires professional installation services to run the fiber-optic cables to your house. Internet providers such as CenturyLink offer both DSL and fiber plans.
Wireless - Radio frequency internet
The RF part of the electromagnetic spectrum is generally defined as that part of the spectrum where electromagnetic waves have frequencies in the range of about 3 kilohertz (3 kHz) to 300 gigahertz (300 GHz).
Wireless - Satellite internet
Satellite internet is a good option if you live in a remote or rural area that doesn’t provide access to fiber, cable or DSL internet connections. However, expect to pay more for satellite internet with lower speeds than you would for other internet technologies offered in urban and suburban areas.
At the core, Starlink offers faster service speeds than HughesNet,
Wireless - Cellular internet
Cellular internet uses a router or hotspot to connect to a provider’s cellular network, just like your mobile phone. The speed you receive depends on how close you are to a network tower, network congestion, how many connected devices you have and other factors.
