Networking Hardware

5 minutes 5 Questions

Networking hardware includes devices and components that allow computers and other devices to communicate and share data over a network. Routers, switches, and hubs are examples of networking devices that facilitate the flow of data between connected systems. Routers connect multiple devices on a local network to the internet, assigning unique IP addresses and managing data traffic. Switches facilitate data transmission across a network by creating dedicated channels for communication between devices. Hubs, now less common, serve a similar purpose but are more limited than switches, as they broadcast data to all connected devices rather than specific communication channels. Wireless Access Points (WAPs) extend the reach of a wireless network, while network interface cards (NICs) allow devices to connect to a network.

A Guide on Networking Hardware for CompTIA A+

Importance:
Networking Hardware is a crucial part of the CompTIA A+ certification as it forms the foundation of computer networks. Understanding this helps in managing, maintaining, troubleshooting, installing and configuring devices for a network infrastructure.

What is Networking Hardware:
Networking Hardware refers to the physical devices used to interconnect computers and servers to form a network. These include devices such as routers, switches, access points, and network interface cards.

How it Works:
Each device in Networking Hardware plays a unique role in receiving, transmitting and controlling network traffic. For example, routers connect different networks and route network traffic between them.

Question 1

A small business is experiencing slow network speeds and frequent disconnections. What should you do to improve the network?

Replace the hub with a switch Change Ethernet cables Place a second router in another room Add additional Access Points

Correct Answer: Replace the hub with a switch

Hubs can lead to slow network speeds and disconnections, as they transmit data packets to all devices. Replacing a hub with a switch minimizes collisions and improves the network's efficiency, reducing the chances of the stated issues.

Question 2

Your client's network experiences intermittent connectivity issues. All cables and network devices appear to be working correctly. What could be causing the problem?

Too many network devices Faulty switch Low bandwidth Electromagnetic interference

Correct Answer: Electromagnetic interference

Electromagnetic interference (EMI) is the most likely cause of intermittent connectivity issues when all cables and network devices appear to be working correctly. EMI can disrupt network signals, leading to temporary loss of connectivity or reduced performance. Low bandwidth would result in consistently slow speeds rather than intermittent issues. A faulty switch or too many network devices would typically cause more persistent problems, not intermittent ones, if all devices appear to be functioning properly.

Question 3

A medium-sized company is planning to open a new office that requires a stable and high-speed network connection. What type of cable would you recommend?

Cat 6a Ethernet Cable Cat 5e Ethernet Cable Coaxial Cable Cat 5 Ethernet Cable

Correct Answer: Cat 6a Ethernet Cable

For a medium-sized company opening a new office that requires a stable and high-speed network connection, Cat 6a Ethernet cable is the best choice. Cat 6a offers faster data transfer speeds (up to 10 Gbps) and can support longer cable runs compared to older categories like Cat 5 and Cat 5e. It also provides better crosstalk resistance and noise reduction, ensuring a more stable connection. Coaxial cable is not suitable for modern Ethernet networks and is typically used for cable television or internet service provider connections.
