CompTIA Network+ Essentials: Cabling and Network Basics Quiz

Network cabling refers to the medium through which data is transmitted in a network. While Ethernet, fiber optic, and coaxial cables are commonly used in network cabling, the correct answer for this specific question is from the CompTIA Networking Concepts - Cable Types Card 2.

The correct answer refers to a specific source that covers the different types of cables used in networking. The incorrect answers are common types of cables used in networking, but they do not encompass the entirety of cable types mentioned in the original question.

Coaxial cables have various types and each type is used for specific applications based on their quality and transmission loss characteristics.

Plenum cable refers to a specific type of cable with fire resistant properties involving Teflon insulation, it is generally more expensive and less flexible than PVC cables.

Twisted pairs refer to the twisting of two insulated wires around each other, which reduces crosstalk between them and is commonly used in cables for telephones and computer network technology.

STP cabling is known for its superior interference prevention when compared to UTP, but it comes at a higher cost and installation complexity. Additionally, UTP cables have lower attenuation compared to STP or co-axial cables.

Fiber-optic cable is a cabling technology that utilizes optical fibers to transmit data signals via light pulses. It is different from cables that use electricity, copper wire, or radio waves for data transmission.

RS-232, also known as Recommended Standard 232, is the standard for serial binary data interconnection used in computer serial ports. It is prone to crosstalk problems due to its poor control of signal rise and fall times.

AUI stands for Attachment Unit Interface, which is a 15-pin connector used to attach cables to Ethernet cards.

The most common connectors used with fiber optic cables are ST and SC connectors.

IDC/UDC connectors are specifically designed for terminating 2-pair STP cable by piercing the insulation on the cable and making contact with the wire conductor, they are not used for connecting fiber optic cables, transmitting wireless signals, or regulating power supply.

Network addressing involves the use of Internet addresses, such as IP addresses, to identify terminals within a network. The correct answer provides a comprehensive explanation of network addressing, including the use of network and host addresses to uniquely identify nodes within a network.

The key topics covered in CompTIA+ Networking Concepts - Addressing include various addressing concepts such as IP addressing, subnetting, and addressing schemes.

Bandwidth specifically refers to the data transmission capacity of a network, not to the speed of a computer booting up, the colors a printer can print, or the storage space on a hard drive.

Network Protocols are a set of rules that enable communication between different devices in a network, and they operate at multiple layers of the network models. It is not limited to software applications, physical devices, or security tools.

Network protocols are a set of guidelines that govern how computers communicate over a network. They dictate how data communication devices must understand and accept to be able to talk to each other.

TCP provides reliable transmission of data by ensuring that information reaches the destination and re-transmitting missing parts in case of network congestion or losses. IP provides addressing over the Internet, and UDP offers best-effort delivery of data with less transmission overhead than TCP. HTTP is a different protocol used for web communication.

The Transport control field in the NetWare IPX Packet Header indicates the number of routers from which the packet has passed.

Topology refers to the physical or logical layout of a network. It determines how devices are interconnected and how data is transmitted between them.

The star topology connects all systems to a central node, reducing the chance of network failure by isolating any peripheral node failures from affecting the rest of the systems.

Networking models provide a standard framework for designers to follow when designing complex communication systems, allowing them to solve issues separately. It is not a rigid method, but a flexible framework that can be adapted based on the specific goals of the implementers.

Peer-to-peer networks are characterized by all computers being able to act as both clients and servers, with no dedicated servers. This type of network is recommended for smaller networks due to its easy installation and relatively low setup costs.
