计算机网络英文名词解释

计算机网络英文名词解释如下：
1. Network: A network is a collection of interconnected devices, such as computers, servers, routers, switches, etc., that are linked together to facilitate communication and data sharing.
2. Protocol: A protocol is a set of rules and guidelines that govern the communication between devices in a network. It defines how data is transmitted, received, and interpreted.
3. IP Address: An IP address is a unique numerical label assigned to each device connected to a network. It is used to identify and locate devices in a network using the Internet Protocol (IP).
4. Router: A router is a networking device that forwards data packets between different networks. It determines the best path for data transmission based on the destination IP address.
5. Switch: A switch is a networking device that connects multiple devices within a local area network (LAN). It forwards data packets between devices based on their MAC addresses.
6. Firewall: A firewall is a security device or software that monitors and controls incoming and outgoing network traffic. It acts as a barrier between a trusted internal network and an untrusted external network, filtering out potentially harmful data.
7. DNS (Domain Name System): DNS is a system that translates domain names (e.g., www.example.com) into IP addresses. It allows users to access websites using human-readable domain names instead of numerical IP addresses.
8. DHCP (Dynamic Host Configuration Protocol): DHCP is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. It simplifies the process of network＊＊＊ is a secure connection that allows users to access a private network over a public network, such as the internet. It provides encryption and authentication to ensure secure data transmission.
10. LAN (Local Area Network): A LAN is a network that connects devices within a limited geographical area, such as a home, office, or building. It allows for local data sharing and communication between devices.
11. WAN (Wide Area Network): A WAN is a network that spans a large geographical area, connecting multiple LANs or other networks. It enables long-distance communication and data transfer.
12. TCP/IP (Transmission Control Protocol/Internet Protocol): TCP/IP is a set of protocols that form the foundation of the internet and most computer networks. It provides reliable and standardized communication between devices.
13. Bandwidth: Bandwidth refers to the maximum amount of data that can be transmitted over a network connection in a given time period. It is typically measured in bits per second (bps) or megabits per second (Mbps).
14. Latency: Latency is the time delay between the transmission and reception of data over a network. It is influenced by factors such as distance, network congestion, and processing time.
15. Packet: A packet is a unit of data that is transmitted over a network. It contains both the data being transmitted and control information, such as source and destination addresses.
