What is the purpose of a Cat 5 cable?
Cat 5 cables are used to support Ethernet networking at speeds up to 1 Gbps (1000BASE-T) over a maximum distance of 100 meters. They provide twisted pair copper cabling for transmitting data in local area networks (LANs).
What is the purpose of a Cat 5e cable?
Cat 5e (enhanced) cables are an improved version of Cat 5 cables, designed to reduce crosstalk and electromagnetic interference. They support Ethernet networking at speeds up to 1 Gbps over 100 meters.
What is the purpose of a Cat 6 cable?
Cat 6 cables are used for Ethernet networks requiring higher data transmission rates. They support speeds up to 10 Gbps (10GBASE-T) over shorter distances—up to 55 meters unshielded or 100 meters when shielded.
What is the purpose of a Cat 6a cable?
Cat 6a (augmented) cables are designed to support 10 Gbps Ethernet over longer distances up to 100 meters. They offer improved shielding and reduced crosstalk.
What is the purpose of a coaxial cable?
Coaxial cables transmit high-frequency signals over a central conductor surrounded by shielding. They are commonly used for cable television, cable modems, and broadband internet services, providing reliable signal transmission with protection against interference.
What is the purpose of a shielded twisted pair cable?
Shielded Twisted Pair (STP) cables are used in environments with high electromagnetic interference. The shielding around the pairs and/or the overall cable protects against interference, ensuring signal integrity.
What is the purpose of a direct burial STP cable?
Direct burial STP cables are designed for underground installations without the need for conduit. They are waterproof and often gel-filled to repel moisture, making them suitable for outdoor networking applications.
What is the purpose of a unshielded twisted pair cable?
Unshielded Twisted Pair (UTP) cables are the most common type of network cabling. They are used in standard Ethernet networks in environments with minimal electromagnetic interference.
What is the purpose of a USB 2.0 cable?
USB 2.0 cables are used to connect peripherals like keyboards, mice, printers, and storage devices to computers. They support data transfer speeds up to 480 Mbps over distances up to 5 meters.
What is the purpose of a USB 3.0 cable?
USB 3.0 cables, also known as SuperSpeed USB, connect high-speed peripherals like external hard drives and high-definition webcams to computers. They support data transfer speeds up to 5 Gbps over approximately 3 meters.
What is the purpose of a serial cable?
Serial cables facilitate serial communication between devices using protocols like RS-232. They are commonly used to connect modems, printers, or to configure network hardware such as routers and switches via console ports.
What is the purpose of a Thunderbolt cable?
Thunderbolt cables provide high-speed data transfer and power delivery over a single cable. They are used to connect devices like external monitors, storage solutions, and to daisy-chain multiple peripherals with data transfer rates up to 40 Gbps (Thunderbolt 3).
What is the purpose of a HDMI cable?
HDMI cables transmit high-definition digital video and audio signals between devices. They are commonly used to connect computers, gaming consoles, Blu-ray players, and set-top boxes to TVs and monitors.
What is the purpose of a DisplayPort cable?
DisplayPort cables are used to transmit digital video and audio signals from a computer to a display. They support high resolutions and refresh rates, and can be adapted to HDMI and DVI interfaces.
What is the purpose of a DVI cable?
DVI cables transmit digital and analog video signals between computers and monitors. They support various resolutions through single-link and dual-link configurations but do not carry audio signals.
What is the purpose of a VGA cable?
VGA cables transmit analog video signals from a computer to a monitor or projector. They are characterized by a 15-pin connector and are used for displaying video without audio, typically in older systems.
What is the purpose of a SATA cable?
SATA cables connect internal storage devices like hard drives and optical drives to a computer’s motherboard. They facilitate high-speed data transfer within the system.
What is the purpose of a SCSI cable?
SCSI cables connect multiple peripheral devices such as hard drives, scanners, and printers to a computer system using the Small Computer Systems Interface. They allow for daisy-chaining multiple devices over a single bus.
What is the purpose of a eSATA cable?
eSATA cables connect external storage devices to a computer, providing high-speed data transfer rates similar to internal SATA connections but designed for external use.
What is the purpose of a IDE cable?
IDE cables, also known as PATA cables, connect internal storage devices to the motherboard in older computer systems. They facilitate data transfer over a parallel interface.
What types of cables use a RJ11 connector?
Telephone cables for analog phone lines and DSL internet connections use RJ11 connectors.
What types of cables use a RJ45 connector?
Ethernet network cables, such as Cat 5, Cat 5e, Cat 6, and Cat 6a twisted pair cables, use RJ45 connectors.
What types of cables use a F type connector?
Coaxial cables used for cable television and cable internet services, Like RG-6, use F type connectors.
What types of cables use a ST connector?
Fiber optic cables, particularly multimode fiber cables, use ST (Straight Tip) connectors.
