What is the maximum supported bandwidth for a Category 5 twisted pair cable specified under TIA EIA 568 standards quizlet?

Data is moved from one device to another in chunks called frames. NICs create and process frames. Every NIC has a built in identifier, an address unique to that network card, called a media access control (MAC) address. A MAC address is a binary number.

A MAC address is 48 bits long and represented in hexadecimal characters from A-F and 0-9. The first half of the MAC address is the manufacturer and the other half is unique to that manufacturer.

First, frames contain the MAC address of the network card to which the data is being sent. Second, they have the MAC address of the network card that sent the data. Third, the data itself, which can very depending on the type of frame. Finally, frames must contain some type of check to verify that the data was sent good. Most frames use an algorithm called the cyclic redundancy check (CRC).

Frames are made of four parts: the recipient MAC, sender MAC, data, and the CRC.

Light can be sent down a fiber optic cable as regular light or laser light. Each type of light requires different fiber optic cables. Most network technologies that use fiber optics use LEDs to send light signals. These use multimode fiber optic cabling. Multimode fiber transmits multiple light signals at the same time, each using a different reflection angle within the core of the cable. Multimode is used for short distances (for fiber).

Network technologies that use laser light use single-mode fiber optic cabling. Using laser light and single mode fiber optic cables allows for phenomenally high transfer rates over long distances. Except for long distances, single mode is currently quite rare; if you see fiber optic cabling, it is more than likely multimode.

If you want to use fiber optics, you need a fiber switch and network card.

Multimode overall is slower and has a shorter range than single mode. Typical multimode network runs at 10, 100, 1000, or 10,000 Mbps. Distances for multimode top out at 600 meters. With single mode, speed and distance (depending on the standard) can blow multimode away.

Early versions of Ethernet ran on coaxial cable instead of UTP. Coax cables are rated using an RG name. The two you need to know for CompTIA exam are RG-59 and RG-6. Both standards are rated by impedance, which is measured in ohms. RG-6 and RG-59 have a 75 ohm impedance.

Coax most commonly used two different types of connectors. A BNC (Bayonet Neill-Concelman or British Naval) connector uses a quarter twist connector, and an F-type connector uses a screw connector. A BNC is uncommon, but F-type is common as it is on the ack of all cable modems and most televisions.

Ideally, once you install horizontal cabling, you should never move it. As you know, UTP horizontal cabling has a solid core, making it pretty stiff. Be careful when moving solid core cables around as they can break easily. You can avoid the solid core cables breaking by using a patch panel. A patch panel is a box with a row of female connectors (ports) in the front and permanent connections in the back, to which you connect the horizontal cables.
The most common type of patch panel today uses a special type of connector called a 110 block, or sometimes called a 110 punchdown block. UTP cables connect to a 110 block using a punchdown tool. Patch panels are available with 8, 12, 24, 48, or even more ports.
Patch panels, like UTP cables, come with CAT ratings, which you should be sure to check. Do not put a CAT 6 cable in a cheap patch panel, get the CAT 6 patch panel.
Once you have installed the patch panel, you need to connect the ports to the switch through patch cables. Patch cables are short (two to five foot) UTP cables. Patch cables use stranded rather than solid cable, so they can tolerate more handling.
