An Introduction to Computer Networks - Second Edition: A Free and Open Source Book for Students and Professionals

Are you looking for a PDF book of computer network to learn the basics and advanced concepts of networking? Do you want to download a free and open textbook that covers the LAN, internetworking and transport layers, focusing primarily on TCP/IP? If yes, then you are in the right place. In this article, I will introduce you to one of the best computer network books available online and show you how to download it in PDF format. ## What is a Computer Network? A computer network is a collection of devices that are connected by communication channels that facilitate data transfer and resource sharing among them. A computer network can be classified according to its size, topology, architecture, protocol and application. Some common types of computer networks are: - Local Area Network (LAN): A LAN is a network that connects devices within a small geographic area, such as a home, office or school. LANs typically use Ethernet or Wi-Fi as the medium of communication. - Wide Area Network (WAN): A WAN is a network that spans a large geographic area, such as a country or continent. WANs typically use leased lines, satellite links or cellular networks as the medium of communication. - Metropolitan Area Network (MAN): A MAN is a network that connects devices within a metropolitan area, such as a city or town. MANs typically use fiber-optic cables or wireless technologies as the medium of communication. - Personal Area Network (PAN): A PAN is a network that connects devices within a personal range, such as a few meters. PANs typically use Bluetooth or infrared as the medium of communication. ## What is TCP/IP? TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a suite of protocols that defines how data is transmitted and routed over the internet. TCP/IP consists of four layers: - Application Layer: This layer provides services and interfaces for applications to communicate with each other over the network. Some common application layer protocols are HTTP, FTP, SMTP and DNS. - Transport Layer: This layer provides reliable and efficient data transfer between end hosts. It also handles flow control, congestion control and error detection. Some common transport layer protocols are TCP and UDP. - Internet Layer: This layer provides logical addressing and routing of packets across different networks. It also handles fragmentation and reassembly of packets. The main protocol in this layer is IP. - Link Layer: This layer provides physical access to the network medium and transmission of bits over the wire. It also handles framing, error correction and media access control. Some common link layer protocols are Ethernet, Wi-Fi and PPP. ## Why Choose An Introduction to Computer Networks by Peter L Dordal?
