Cable, Wiring, And Ethernet Specifications - Srickperry

The point at which the operational control or ownership changes from your company to a service provider is commonly known as the "demarcation point." This term is used to define the boundary or separation between the responsibilities and obligations of the two entities involved in the transition. It marks the point where the service provider takes over the management and maintenance of the services or infrastructure provided.

568b is a cross-over cable.

The given correct answer is Cat 1. This is because Cat 1 cable, also known as Category 1 cable, is the oldest type of cable and is only suitable for voice grade communication. It is not rated for data communication. The description provided matches the characteristics of Cat 1 cable, as it is referred to as plain old telephone service (POTS) and was the standard cable used before 1983 in the North American telephone system. Therefore, Cat 1 is the correct answer.

Cat 6 cable is the correct answer because it is a twisted wire pair cable that is rated for 250MHz, making it suitable for connecting floors together. It became a standard in June 2002, indicating its reliability and widespread use. When installing a new network in a new building, Cat 6 cable is recommended due to its superior performance compared to lower category cables such as Cat 1, Cat 2, Cat 3, Cat 4, Cat 5, and Cat 5e. Additionally, running fiber optic cables between floors is also suggested for optimal network connectivity.

568b is a cross-over cable.

A hardware loopback is a type of connector that connects the transmit pins directly to the receive pins. This allows for testing and troubleshooting of network connections by sending data from the transmit pins and receiving it back on the receive pins without the need for an external device or network connection. This type of connector is commonly used in network testing and diagnostics.

568b is a cross-over cable.

Cat 6 UTP wiring uses four twisted wire pairs (8 wires) and is rated for 250Mhz. This means that it is designed to support higher bandwidth and faster data transmission compared to Cat 5, Cat 5e, and Cat 6a. Cat 6 cables are commonly used in Ethernet networks to provide reliable and high-speed connections.

Cat-5e is the correct answer because it uses four twisted wire pairs (eight wires), is rated for 100MHz, and is capable of handling the disturbance on each pair caused by transmitting on all four pairs at the same time. Cat-5 is not capable of handling the disturbance caused by transmitting on all four pairs simultaneously. Cat-6 and Cat-6a have higher bandwidth ratings (250MHz and 500MHz respectively), but they are not necessary for this specific requirement.

Cat 5e is the correct answer because it is capable of handling the disturbance caused by transmitting on all four pairs at the same time, which is necessary for Gigabit Ethernet. The other categories mentioned (Cat 1, Cat 2, Cat 3, Cat 4, Cat 5, and Cat 6) may have different capabilities and may not be able to handle the same level of disturbance.

aka Rollover cable, aka Console cable

The given correct answer, Cat 5, is the most appropriate choice based on the information provided. The statement mentions that there are four twisted wire pairs (eight wires) to reduce cross-talk, which is a characteristic of Cat 5 cables. Additionally, it states that the cables are rated for 100MHz, which is within the capabilities of Cat 5 cables. Therefore, Cat 5 is the suitable option for this scenario.

Cat 3 cables are made up of four twisted wire pairs with three twists per foot. They have a transmission capacity of up to 16MHz. Cat 3 cables were commonly used in the mid-1980s for up to 10Mbps Ethernet. However, they are now considered obsolete for network use and are mainly used in telecommunication equipment.

568a is a Straight-through cable.

568b is a cross-over cable.

CSMA/CD is a protocol used in Ethernet networks to control access to the shared transmission medium. "Carrier Sense" refers to the process of checking if the network is currently being used by another device before transmitting data. "Multiple Access" means that multiple devices can access the network simultaneously. "Collision Detection" is the mechanism used to detect if two devices transmit data at the same time, causing a collision. In such cases, both devices stop transmitting and wait for a random time before retransmitting. Therefore, CSMA/CD is the correct answer as it accurately describes the protocol's functionality.

568a is a Straight-through cable.

RG-6 is the correct answer because it is the most commonly used coaxial cable for cable modems. RG-6 cables have a higher bandwidth capacity and are better suited for transmitting high-frequency signals, making them ideal for high-speed internet connections. They have better shielding and lower signal loss compared to other RG ratings, ensuring reliable and efficient data transmission for cable modems.

The given answer, Cat 4, is the most appropriate choice because it is the highest category listed that can support the specifications provided. Cat 4 cables are capable of transmitting data at speeds up to 20MHz, which matches the rating of the twisted wire pairs mentioned. Additionally, the mention of the cables being obsolete suggests that they are likely older and therefore more likely to be Cat 4 cables, as higher categories such as Cat 5 and above are more commonly used in modern installations.

Cat 2 is the correct answer because it is the closest match to the given description. Cat 2 cables consist of four twisted wire pairs, which matches the description of "Four twisted wire pairs (eight wires)". Cat 2 cables have a maximum data transfer rate of 4Mbps, which matches the given information. The frequency limitation of 10MHz also aligns with Cat 2 cables, as they are designed for lower frequency applications. Additionally, Cat 2 cables are now obsolete, which matches the information provided.
