Networking Fundamentals

By: Gordon Davies

Overview of this book

A network is a collection of computers, servers, mobile devices, or other computing devices connected for sharing data. This book will help you become well versed in basic networking concepts and prepare to pass Microsoft's MTA Networking Fundamentals Exam 98-366. Following Microsoft's official syllabus, the book starts by covering network infrastructures to help you differentiate intranets, internets, and extranets, and learn about network topologies. You’ll then get up to date with common network hardware devices such as routers and switches and the media types used to connect them together. As you advance, the book will take you through different protocols and services and the requirements to follow a standardized approach to networking. You’ll get to grips with the OSI and TCP/IP models as well as IPv4 and IPv6. The book also shows you how to recall IP addresses through name resolution. Finally, you’ll be able to practice everything you’ve learned and take the exam confidently with the help of mock tests. By the end of this networking book, you’ll have developed a strong foundation in the essential networking concepts needed to pass Exam 98-366.

Assigning IP addresses to hosts

It is imperative that, when planning your network, you know which IP addresses can be given out to a host. Once you have identified the network address and broadcast address on a network, you can issue an IP address that sits between them to a host device.

Therefore, the first IP address you can issue to a host is the one immediately following the network address. The last IP address you can issue to a host is the one immediately before the broadcast address.

An IP address can either be assigned manually by an administrator or dynamically through Dynamic Host Configuration Protocol (DHCP). We will talk about DHCP in more detail in Chapter 14, Network Services.

Manually assigning an IP address to a Windows computer involves adjusting the IPv4 properties of the NIC itself. Since a device can have more than one NIC, ensure you are configuring the right...
