Network infrastructure refers to the hardware and software components that enable communication and data exchange within a network. This includes devices like routers, switches, and servers, as well as the physical connections such as cables and wireless signals. Together, these elements create a framework that supports various applications and services. In addition to hardware, network infrastructure encompasses protocols and standards that govern data transmission. These protocols, such as TCP/IP and HTTP, ensure that information is sent and received accurately across different devices. A well-designed network infrastructure is essential for efficient and reliable connectivity in both personal and business environments.
