JUNIOR LEVEL

What is your understanding of network fundamentals, architecture, and protocols?

Sample answer to the question

My understanding of network fundamentals, architecture, and protocols is that they form the foundation of computer networks. Network fundamentals encompass the basic concepts and principles of networking, such as the OSI model, IP addressing, and subnetting. Network architecture refers to the design and structure of a network, including the arrangement of devices, protocols, and services. Network protocols are the rules and standards that govern how data is transmitted and received across a network. I have a basic knowledge of routing, switching, and network protocols like TCP/IP, DNS, and DHCP. I am also familiar with common networking hardware, such as routers, switches, and firewalls. Additionally, I understand the importance of network infrastructure services like Active Directory and LDAP.
