Cable networks: number of viewers in the U.S. December 2020
Jan 26, · Broadly speaking, a network cable is a type of cable wiring used in telecommunications that relays data from individual computers to a larger network mainframe. Sometimes these cables are external, and can be used to do things like plug computers into Internet modems or grounded ports. They can also be part of a larger infrastructure, and in these cases are . Network cables are used to connect and transfer data and information between computers, routers, switches and storage area networks. These cables are essentially the carrier or media through which data flows. There are different types of communications cables, and the appropriate type to use will depend on the structure and topology of the overall architecture of the system.
Even though there have been advances in wireless technologies, many computer networks in the 21st century rely on cables as the physical medium that devices use to transfer data. Several standard types of network cables exist, each designed for specific purposes.
Invented in the s, coaxial cable also called coax was best known as the kind of cable that connected what is a cable network sets to home antennas. Coaxial cable is also a standard for 10 Mbps Ethernet cables. These cables consist of an inner copper wire of varying thickness what is online piracy definition by insulation and another shielding.
Their stiffness caused network administrators difficulty when installing and maintaining thinnet and thicknet. Ethernet twisted pair cables contain up to eight wires wound together in pairs to minimize electromagnetic interference. Two primary types of twisted pair cable industry standards have been defined: unshielded twisted pair UTP and shielded twisted pair STP. Instead of insulated metal wires transmitting electrical signals, fiber optic network cables use strands of glass and pulses of light.
These network cables are bendable despite being made of glass. They have proven especially useful in wide area network WAN installations where long-distance underground or outdoor cable runs are required and also in office buildings where a high volume of communication traffic is common.
Two primary types of fiber optic cable industry standards are defined—single-mode BaseBX standard and multimode BaseSX standard. Long-distance telecommunications networks commonly use single-mode for its relatively higher bandwidth capacity, while local networks typically use multimode due to its lower cost.
Most Universal Serial Bus USB cables connect a computer with a peripheral device such as a keyboard or mouse rather than to another computer. However, special network adapters sometimes called dongles connect an Ethernet cable to a USB port indirectly. USB cables feature twisted-pair what is a cable network. Because many PCs in the s and early s lacked Ethernet capability, and USB had not been developed yet, serial and parallel interfaces now obsolete on modern computers what is a cable network sometimes used for PC-to-PC networking.
So-called null modem cables, for example, connected the serial ports of two PCs and enabled data netwwork at speeds between 0. Null modem cables are one example of the category of crossover cables. Cabble crossover cable joins two network devices of the same type, such what is squad on call of duty ghost two PCs or two network switches.
The use of Ethernet crossover cables was common on older home networks years ago when connecting two PCs directly together. Externally, Ethernet crossover cables appear identical to ordinary cables sometimes called straight-throughthe only visible difference being the order of the color-coded wires appearing on the cable's end connector.
Manufacturers typically applied special neetwork marks to their crossover cables for this reason. Nowadays, though, most home networks utilize routers that have built-in crossover capability, eliminating the need for these special cables. Some networking professionals use the term patch cable to refer to wuat kind us straight-through network cable used for a temporary purpose.
Coax, twisted pair and fiber optic types of patch cables exist. These cables share the same physical characteristics as other types of network cables except that patch cables tend to be a shorter length.

Jun 15, · In the United States, the networks (also known as broadcast television) are ABC, NBC, CBS, FOX, and The CW. Like radio, these networks are nationally transmitted through local affiliates or owned-and-operated stations and can be picked up through a TV antenna. Of course, now viewers can also access them digitally or through cable providers. Sep 18, · An Ethernet cable is a common type of network cable used with wired networks. Ethernet cables connect devices such as PCs, routers, and switches within a local area network. These physical cables are limited by length and durability. If a network cable is too long or of poor quality, it won't carry a good network signal. The Crossword Solver found 20 answers to the cable network crossword clue.
