A is a networking device that connects two networks together, such as a local area network (LAN) and the internet. It acts as a bridge between the two networks, allowing communication to flow between them. A is another essential networking device that forwards data packets between networks. Unlike a , which only forwards data within a single network, a router can send data to different networks.
Within a network, s and s communicate with each other. A client is a device that requests services from a server, while a server is a device that provides those services. s are devices on the same network that have equal standing and can communicate directly with each other.
s and proxies are network security tools used to protect networks from unauthorized access. A firewall is a security system that monitors and controls incoming and outgoing network traffic. It uses to allow or block data packets based on a set of security rules. A server acts as an intermediary between clients and servers, intercepting requests and forwarding them on behalf of the client.
s are devices used to interact with a computer system. They provide a user interface for accessing applications and resources on a server. s are the devices or software applications that initiate and terminate communication sessions within a network. They can be computers, smartphones, IoT devices, or any other network-connected device.
