Computer Network Setup Quiz

A router is a network device that is responsible for forwarding data packets between different networks. It is typically connected to at least two networks, such as two LANs or a LAN and the ISP network. Unlike a hub or switch, which are used for connecting devices within a single network, a router is used for connecting and directing traffic between different networks. Therefore, a router is the correct answer for this question.

Fiber optic cable transmits light instead of electronic signals, which reduces the risks of electrical interference. This is because light signals are not affected by electromagnetic interference, unlike electronic signals. Therefore, fiber optic cables are commonly used in environments where there is a high risk of electrical interference, such as in industrial settings or areas with high levels of electromagnetic radiation.

Network topology refers to the arrangement of devices and computers in a network through connections. It describes how the nodes are connected and the structure of the network. This includes the physical and logical layout of the network, such as the types of connections used (wired or wireless) and the overall architecture (bus, star, ring, etc.). Network topology helps determine how data flows within the network and how devices communicate with each other. It is an essential concept in understanding and managing computer networks.

A Local Area Network (LAN) is a group of computers and connected devices that share a common communication line to a server. This allows for the devices within the LAN to communicate and share resources with each other. The LAN is typically confined to a small geographic area, such as a home, office, or building, and is often used for sharing files, printers, and internet access.

Cable is the correct answer because it is the physical medium that is used to transmit information between network devices. It can be in the form of copper wires, fiber optic cables, or coaxial cables. Without a cable, data cannot be transmitted from one device to another in a network.

A proxy server acts as a buffer between computers and the internet by intercepting requests from clients and forwarding them to the internet on behalf of the clients. It helps to improve security and privacy by hiding the IP addresses of the clients and providing additional layers of protection against cyber threats. Additionally, a proxy server can also cache web content, which helps to improve network performance and reduce bandwidth usage.

A patch panel is used to connect and route circuits for monitoring, interconnecting, and testing circuits in a convenient and flexible network. It helps in organizing network cables in the workplace, minimizing hazards such as hanging and opening cables.

The correct answer is Unshielded Twisted Pair Cable. This type of cable is commonly used for Local Area Networks (LANs) because it is cost-effective and provides good performance for short to medium distances. It consists of two insulated copper wires twisted around each other, which helps to reduce electromagnetic interference. Unlike shielded twisted pair cables, it does not have additional shielding layers, making it easier to install and more flexible.

T568B is the most commonly used wiring standard in computer network setups for Ethernet networking and cables. This standard specifies the arrangement of the wires inside an Ethernet cable, ensuring compatibility and proper functioning of the network. T568B provides a standardized approach to networking infrastructure and is widely adopted worldwide.

The correct answer is Green Stripe, Green, Orange Stripe, Orange. In a crossover cable, the wires are rearranged to allow for direct communication between two devices without the need for a network switch. The T568A and T568B are two different wiring standards commonly used for Ethernet cables. In T568A, the green and orange pairs are swapped, so the green stripe and green wires change places, and the orange stripe and orange wires change places.
