Question

Transport layer ports 1 through _______ are used to identify well-known ports.

a) 100
b) 255
c) 1023
d) 65535

Answer 1

Transport layer ports 1 through 1023 are designated for well-known ports, which allow for the standardization of commonly used services and are important in network configuration.

Step-by-step explanation:

The range of transport layer ports from 1 through 1023 is designated for well-known ports. These ports are assigned by the Internet Assigned Numbers Authority (IANA) and are generally used by system- or well-known server processes. Well-known ports facilitate the standardization of services, allowing systems to easily recognize common services such as HTTP (port 80) or FTP (port 21). It is important to know these port numbers when configuring firewalls, routers, or when working with various network services and protocols.
