Explain the role of a network interface card (NIC) and how it facilitates communication between a computer and cabling.
A network interface card (NIC) serves as the physical interface between a computer and cabling. It prepares, sends, and controls the flow of data, while also receiving and translating data into bytes for the CPU to understand. NICs come in various shapes and sizes, and their compatibility with the PC's bus type is crucial for proper functioning.
What factors should be considered when evaluating the compatibility of a NIC with a PC?
When evaluating the compatibility of a NIC with a PC, the primary factor to consider is whether the NIC fits the bus type of the PC. If the PC has multiple bus types, the NIC should be chosen based on the fastest type, such as PCI Express. Ensuring compatibility is essential for seamless integration and optimal performance.
Explain the purpose of connectivity devices in a network.
Connectivity devices are used to attach multiple computers or networks to each other. These devices enable the establishment of communication channels and facilitate the transfer of data between computers or networks. Examples of connectivity devices include switches, routers, and hubs.
What are the key components required for a computer to connect to a network?
To connect a computer to a network, two key components are necessary: a network adapter (NIC) and a cable for physical connection. The NIC serves as the interface between the computer and the cabling, allowing data transmission, while the cable ensures the physical connection between the computer and the network.
Explain the different types of twisted-pair cables commonly used in networking.
There are three common types of twisted-pair cables used in networking: shielded twisted-pair (STP), unshielded twisted-pair (UTP), and coaxial twisted-pair (CTP). STP features an extra layer of braided foil shielding to reduce electrical interference, UTP is the most commonly used for Ethernet connections, and CTP combines coaxial and twisted-pair cabling.
What is the maximum transmission distance for unshielded twisted-pair (UTP) cables?
The maximum transmission distance for UTP cables is 100 meters. This limitation is important to consider when planning the layout of a network and determining the placement of devices.
Why is wireless networking considered an exception when it comes to the need for physical connectivity?
Wireless networking is considered an exception to the need for physical connectivity because it allows devices to connect to a network without the use of cables. However, it's important to note that wireless networks still have components, such as routers and access points, that are wired together at the backend.
Explain the difference between shielded twisted-pair (STP) and unshielded twisted-pair (UTP) cables.
STP cables have an extra layer of braided foil shielding to reduce electrical interference, while UTP cables have no outer shield.
