Nke a bụ ndepụta okwu a na-ejikarị na netwọk:
IP address: Every device on a network has a unique IP address. IP address is used to identify a device on a network. IP stands for Internet Protocol.
Nodes: A node is a device that is connected to a network. Examples of nodes include computers, printers, and routers.
Routers: A router is a device that forwards data packets between networks.
Switches: A switch is a device that connects multiple devices together on the same network. Switching allows for data to be sent only to the intended recipient.
Ụdị mgbanwe:
Circuit switching: In circuit switching, the connection between two devices is dedicated to that specific communication. Once the connection is established, it cannot be used by other devices.
Packet switching: In packet switching, data is divided into small packets. Each packet can take a different route to the destination. Packet switching is more efficient than circuit switching because it allows multiple devices to share the same network connection.
Message switching: Message switching is a type of packet switching that is used to send messages between computers.
Ports: Ports are used to connect devices to a network. Each device has multiple ports that can be used to connect to different types of networks.
