Célcím

Célcím is a Hungarian word that translates to "target address" in English. It is most commonly used in the context of computing and networking to refer to the destination of data transmission. When a device sends information across a network, it specifies a célcím to ensure the data reaches the correct recipient. This address can take various forms depending on the network protocol being used. For instance, in the Internet Protocol (IP), the célcím is an IP address, which uniquely identifies a device on the internet. Similarly, in local area networks (LANs), a Media Access Control (MAC) address serves as a physical célcím for devices.

The concept of célcím is fundamental to directed communication. Without a clearly defined destination, data packets would be unable to navigate networks effectively, leading to misdelivery or loss of information. Network devices like routers and switches use the célcím to make forwarding decisions, directing traffic towards its intended endpoint. In some applications, such as email, the célcím is an email address, which is a human-readable identifier that is then translated into a network-specific address for delivery. The accuracy and validity of the célcím are therefore critical for successful data exchange.
