A wired network is a type of computer network that uses physical cables, such as Ethernet cables, to connect devices and facilitate data transmission. This type of network is known for its reliability, speed, and security, making it ideal for environments where stable and high-speed connections are essential, such as offices and data centers. On the other hand, a wireless network uses radio waves to connect devices without the need for physical cables. This allows users to move freely within the network's coverage area while maintaining a stable internet connection. Wireless networks provide convenience, flexibility, and ease of installation, making them suitable for homes, offices, and public spaces. Both wired and wireless networks have their own advantages and are often used in combination to create a robust and versatile networking environment. A firewalled network is a network protected by a firewall, a security device or software that monitors and controls incoming and outgoing network traffic based on predetermined security rules. The primary purpose of a firewall is to create a barrier between a trusted internal network and untrusted external networks, such as the internet, to prevent unauthorized access, cyber threats, and malicious activities. Firewalls can be configured to allow or block specific types of traffic, helping to safeguard sensitive data and resources within the network. Overall, a firewalled network enhances security and provides a safer, more controlled environment for communication and data exchange.
