The process of changing the characteristics of a transmission medium, like electric current or radio waves, to represent data.

A range of frequencies that a transmission medium can support, allowing more data to be transferred at higher frequencies.

Units of measurement for the rate of data transfer, typically expressed in bits per second (bps) or multiples thereof.

Representing information using patterns of ones and zeros, the fundamental language of computers.

Methods used to convert digital data into a signal suitable for transmission over a network.

A set of rules and specifications defining how data is transmitted over a network cable, including cable type, connector type, and signal characteristics.

A unique identifier for an Ethernet standard, using a three-part naming convention (e.g., 10BASE-T). It tells you the data transfer speed, signal type (baseband), and media type.

Copper cable is used to transmit electrical signals between network devices. Two main types exist: twisted pair and coaxial (coax).

Twisted pair cable is classified into categories (Cat) based on its bandwidth capacity and transmission distance.

Signals weaken as they travel over long distances in copper cable. This is known as attenuation.

A network technology where multiple devices share a common communication medium, like a cable.

The methods used by a network to regulate communication on a shared medium, ensuring orderly data exchange.

A network situation where two or more devices try to transmit data at the same time, resulting in signal interference.

A contention-based MAC system used by Ethernet to handle collisions and provide access to the shared medium.

A group of devices that share the same physical transmission medium and can potentially collide with each other.

A signal sent out by a network device when a collision is detected, alerting other devices on the shared medium. It stops further transmissions.

A technique used by network devices involved in a collision to wait for a random period before attempting to retransmit data.

A communication method where a device can either transmit or receive data at a time, not both simultaneously.

A network technology with a data transfer rate of 100 Mbps, using Cat 5 or better twisted pair copper cable for a maximum distance of 100 meters.

A communication method where a device can send and receive data simultaneously, allowing for greater efficiency and speed.

A protocol that allows network devices to automatically negotiate the best connection parameters (speed and duplex mode) for communication.

A type of signal sent by a network device to advertise its capabilities and communicate with other devices.

A switch is a network device that uses information about source and destination addresses to create temporary circuits between connected devices, improving efficiency and eliminating collisions.

A hub is a network device that simply forwards data to all connected devices without any intelligence, leading to collisions in busy environments.

A group of network devices that share the same physical transmission medium and can potentially interfere with each other's data transmissions.

Gigabit Ethernet, also known as 1000BASE-T, uses copper cabling (Cat 5e or better) to achieve a data transfer rate of 1,000 Mbps (1 Gbps).

Gigabit Ethernet networks only use switches, eliminating the possibility of collisions by creating separate paths for each device.

Gigabit Ethernet supports a maximum cable distance of 100 meters, which is the same as Fast Ethernet.

10 Gigabit Ethernet (10 GbE) transmits data at 10,000 Mbps, ten times faster than Gigabit Ethernet. This high speed requires specialized cabling like Cat 6A or fiber optic for longer distances.

40GBASE-T uses Cat 8 cabling and can achieve data transfer rates of 40 Gbps, but is limited to a maximum distance of 30 meters.

10/40 GbE Ethernet is often used in high-bandwidth applications like data centers and TV production, but it can be expensive to implement.

10/40 GbE Ethernet is commonly used as backbone cabling, connecting high-speed components in data centers and network infrastructure.

Uses infrared light signals, making it less susceptible to interference and noise, and supporting higher bandwidth over longer distances compared to copper cable.

A type of fiber optic cable that transmits light signals in a single path, allowing for long-distance transmission with minimal signal loss.

A type of fiber optic cable transmitting light signals along multiple paths, suitable for shorter distances but offering lower cost.

A classification of Multimode Fiber (MMF) cables based on bandwidth capacity and transmission distance. OM1, OM2, OM3, and OM4 are increasingly advanced and support higher speeds.

A group of standards defining the use of fiber optic cable for various Ethernet speeds (100 Mbps, 1 Gbps, 10 Gbps, 40/100 Gbps) and transmission distances.

Refers to the use of longer wavelengths (around 1300 nm) that are ideal for long-distance transmission in fiber optic cables.

Refers to the use of shorter wavelengths (around 850 nm) that are typically used for shorter distances in fiber optic cables.

A family of standards defining the use of fiber optic cable for data transfer rates up to 10 Gbps, specifying cable type, connector type, and maximum transmission distance.

Converting digital signals into analog signals for transmission over telephone lines.

Securing network data by encrypting information before transmission, making it unreadable to unauthorized parties.

The physical components used to transmit network data, such as cables, switches, and routers.

A convention for naming Ethernet media specifications, including the speed, signal mode (baseband), and cable type.

Ethernet uses baseband transmission, which means sending data as a single continuous signal.

The type of cable used in a network determines the maximum distance and speed of data transmission.

A network device that can forward data to specific destinations, avoiding collisions and improving network performance.

A network device that simply forwards data to all connected devices without intelligent forwarding, often leading to collisions.

A communication method where a device can send and receive data simultaneously, allowing for greater efficiency and speed.

Occurs when two or more devices attempt to transmit data at the same time on a shared network medium, resulting in signal interference.

A MAC system where devices listen to the network before transmitting, and then back off if they detect a collision, allowing for shared access in a less controlled way.

In a contention-based MAC system, the likelihood of collisions increases as more devices are added to the network, leading to slower data transfer rates.

A way to improve data transfer rates by allowing devices to transmit and receive data simultaneously.

A network situation where two or more devices try to transmit data at the same time, resulting in signal interference, preventing data from being successfully transmitted.

The effective data transfer rate of a network is reduced when more nodes are added due to increased collisions and the need to resolve them.

The frequency of collisions in a network is not directly related to its vulnerability to eavesdropping. Network security measures are more critical for protecting data from unauthorized access.

Replacing existing hubs with switches is the most effective way to improve network performance when integrating new workstations into a 100BASE-TX Fast Ethernet network. Switches manage collision domains more efficiently than hubs, enabling full-duplex transmission and allowing each node to utilize the full bandwidth of the cable link to the switch port.

10/40 GbE Ethernet can support very high bandwidth data transfers, essential for tasks like TV and film production, where large files need to be transferred quickly.

Fiber optic cables offer significantly higher bandwidth and longer transmission distances compared to copper cables. This allows data to travel faster and farther without losing signal quality.

A school network using 100BASE-TX Fast Ethernet with a mix of hubs and switches should prioritize replacing hubs with switches to improve network performance and prepare for future upgrades.

While fiber optic backbones offer benefits, for a 100BASE-TX network with workstations within the 100-meter range, UTP cables are sufficient and more cost-effective for horizontal links.

Autonegotiation is crucial for compatibility between devices with different Ethernet capabilities but doesn't directly address the challenge of integrating new workstations in a 100BASE-TX network.

Extending a fiber optic backbone to every workstation in a 100BASE-TX network is impractical and expensive, especially when distances are within the standard's 100-meter limit.

UTP-based horizontal links are more suitable for connecting workstations to the nearest network switch in a 100BASE-TX environment, as they offer a cost-effective solution within the standard's distance limitations.

While 10/40 GbE Ethernet is expensive, it is necessary in certain applications like TV and film production where high bandwidth data transfers are essential.

10/40 GbE Ethernet offers the highest bandwidth capabilities, enabling large file transfers at incredible speeds. This is crucial for industries like TV and film production.

UTP cable pairs are twisted at different rates to minimize interference from external sources and crosstalk from adjacent pairs within the same cable. This twisting is not intended to increase flexibility.

Solid cabling uses a single thick wire per conductor and is used for permanent installations because of its lower attenuation over longer distances. Stranded cabling is used for flexible patch cords for connecting devices, not for permanent installations.

Screened cabling, often designated as ScTP or F/UTP, features a single thin foil shield that encompasses all wire pairs within the cable, providing a moderate level of shielding against electromagnetic interference.

Fully shielded cabling, often referred to as S/FTP, uses foil-shielded pairs and includes a braided outer screen or an additional foil shield for comprehensive protection against interference.

Fully shielded cabling offers the highest level of protection against interference due to its combination of individual pair shielding and an overall cable shield.

Fully shielded cabling, due to its extensive shielding, is typically used for applications where electromagnetic interference is prevalent and reliability is crucial.

While twisting pairs within UTP cable helps reduce interference, it does not change the cable's thickness. The thickness is determined by the gauge of the wire used.

The color-coding of pairs within UTP cables is mainly for identification, not the primary reason for twisting them. The main purpose of twisting is to reduce interference.

RG-6 coaxial cable is preferred for broadband internet applications due to its thicker core and better impedance characteristics, which allow it to handle the high bandwidth required.

In-vehicle networking demands cables that withstand the harsh electrical environment and limited space within vehicles. RG-59, primarily used for audio/video applications, isn't designed for automotive environments.

Twinaxial cables excel in data center interconnects, handling high-speed data transfer at 10GbE and 40GbE over short distances. Residential telephone wiring uses twisted pair cables, which suffice for lower bandwidth needs.

Outdoor lighting systems utilize electrical power cables designed for harsh outdoor conditions, unlike twinaxial cables which are optimized for data transmission.

Automotive audio systems rely on standard audio cables or car-specific wiring. Twinaxial cables are specialized for high-speed data transfer, not audio signal transmission.

Organizations responsible for creating categories of cable standards for twisted pair cables. These categories help simplify cable selection for different telecommunications applications.

The center two contacts in an RJ11 connector are used to carry the dial tone and voice circuit for typical phone connections.

RJ45 connectors are used for Ethernet cables. They are larger than RJ11 connectors and have 8 positions and 8 contacts.

Plenum-rated cables meet stricter fire safety standards compared to riser-rated cables. This makes them suitable for use in environments like plenum spaces (air handling spaces in buildings).

Plenum-rated cable is fire-resistant and non-toxic, making it safe for use in air handling spaces like false ceilings.

RG-59 coaxial cable is used in audio/video and closed circuit TV (CCTV) applications due to its thinner, more flexible design and ability to transmit signals over short distances.

The American National Standards Institute (ANSI) and the Telecommunications Industry Association (TIA)/Electronic Industries Alliance (EIA) are responsible for creating categories of cable standards for twisted pair cables.
