What is (Computer) Networking?
Networking is the practice of linking computing devices together with hardware and software that supports data communications across these devices.
Networking Basics Quiz / Q&A
Answer this series of common questions about basic computer networking concepts to quickly expand your knowledge of the topic.
Visual Networking Basics
This guide presents the essential concepts of computer networks in a sequence of visual illustrations designed to teach networking basics by example.
Network File Sharing 101
Computer networks allow you to share files with friends, family, coworkers and customers. Learn about the different methods for file sharing including Windows, FTP, P2P and Web based.
Connecting Two Computers
The simplest kind of home network contains exactly two computers. You can use this kind of network to share files, a printer or another peripheral device, and even an Internet connection. To connect two computers for sharing network resources, consider these alternatives.
Introduction to Area Networks and Network Types
LAN and WAN are two common types of networks but many others exist.
Basic Network Topologies
One way to classify computer networks is by their topology. Common network topologies include the bus, star, and ring.
Free Computer Networking Books
Numerous published books are available for free download on the Internet. However, not very many quality, free titles are available on basic computer networking topics.
Network Routers
A router is a small hardware device that joins multiple networks together. These networks can include wired or wireless home networks, and the Internet.
What Is a Network Protocol?
Protocols serve as a language of communication among network devices. Network protocols like HTTP, TCP/IP, and SMTP provide a foundation that much of the Internet is built on. Find out more about these protocols and how they work.
What Is a Server?
In computer networking, a server is a computer designed to process requests and deliver data to other computers over a local network or the Internet. Common types of network servers include Web, proxy and FTP servers.
TCP/IP - Transmission Control Protocol / Internet Protocol
TCP/IP provides connection-oriented communication between network devices. TCP/IP is very commonly used both on the Internet and in home computer networks.
Firewalls
A network firewall guards a computer against unauthorized network access. Firewalls are one of the essential elements of a safe home or business network.
Networking Basics: Ethernet
Ethernet is a physical and data link layer technology for local area networks (LANs). Ethernet is reliable and inexpensive, the leading standard worldwide for building wired LANs.
Networking Basics: Switch
A network switch is a small hardware device that joins multiple computers together at a low-level network protocol layer. Switches differ in important ways from both routers and hubs.
Network Addresses
Network addresses give computers unique identities they can use to communicate with each other. Specifically, IP addresses and MAC addresses are used on most home and business networks.
Basic Computer Architecture
Understanding these concepts in computer architecture is essential to learning computer networking. Discover the fundamental elements of computer system and network architecture here.
Computer Networks , Tanenbaum, 4th Edition



Author: Andrew S. Tanenbaum

Format: pdf

From the Publisher:
The world's leading introduction to networking—fully updated for tomorrow's key technologies.

Computer Networks, Fourth Edition is the ideal introduction to today's networks—and tomorrow's. This classic best seller has been thoroughly updated to reflect the newest and most important networking technologies with a special emphasis on wireless networking, including 802.11, Bluetooth, broadband wireless, ad hoc networks, i-mode, and WAP. But fixed networks have not been ignored either with coverage of ADSL, gigabit Ethernet, peer-to-peer networks, NAT, and MPLS. And there is lots of new material on applications, including over 60 pages on the Web, plus Internet radio, voice over IP, and video on demand.Finally, the coverage of network security has been revised and expanded to fill an entire chapter.

Author, educator, and researcher Andrew S. Tanenbaum, winner of the ACM Karl V. Karlstrom Ou***anding Educator Award, carefully explains how networks work on the inside, from underlying hardware at the physical layer up through the top-level application layer. Tanenbaum covers all this and more:

Physical layer (e.g., copper, fiber, wireless, satellites, and Internet over cable)
Data link layer (e.g., protocol principles, protocol verification, HDLC, and PPP)
MAC Sublayer (e.g., gigabit Ethernet, 802.11, broadband wireless, and switching)
Network layer (e.g., routing algorithms, congestion control, QoS, IPv4, and IPv6)
Transport layer (e.g., socket programming, UDP, TCP, RTP, and network performance)
Application layer (e.g., e-mail, the Web, PHP, wireless Web, MP3, and streamingaudio)
Network security (e.g., AES, RSA, quantum cryptography, IPsec, and Web security)
The book gives detailed descriptions of the principles associated with each layer and presents many examples drawn from the Internet and wireless networks.
