Networking Introduction
This networking tutorial is primarily about TCP/IP network protocols and ethernet network architectures, but also briefly describes other
protocol suites, network architectures, and other significant areas of
networking.
|
Networking Topology
A network consists of multiple computers
connected using some type of interface, each having one or more interface devices such as a Network Interface Card (NIC) and/or a serial device for PPP networking.
|
Networking Hardware Connections
On a network, a hub is basically a repeater which is used to re-time and amplify the network signals.
|
Networking TCP/IP Ports
TCP/IP Ports and Addresses.
|
Networking Protocol Levels
Network Protocol Levels.
|
Networking Data Link Layer
The Data Link Layer and IEEE.
|
Networking Protocol Categories
Networking Protocol Categories.
|
Networking Repeaters
Repeaters, Bridges, Routers, and Gateways.
|
Networking ARP Address
ARP and RARP Address Translation.
|
Networking Basic Addressing
IP addresses are broken into 4 octets (IPv4) separated by dots called dotted decimal notation.
|
Networking Internet Protocol
Internet Protocol.
|
Networking Transport
Transmission Control Protocol (TCP) supports the network at the transport layer.
|
Networking UDP
User Datagram Protocol (UDP) supports the network at the transport layer.
|
Networking ICMP
Internet Control Message Protocol (ICMP) defined by RFC 792 and RFC 1122 is used for network error reporting and generating messages that require attention.

Networking Wireless Media
This section may be skipped by all readers and used by those interested in wireless network technology.
|
Networking Outside Connections
Outside Connections.
|
Networking Ethernet
The IEEE 802.3 standard defines ethernet at the physical and data link layers of the OSI network model.
|
Networking Token Ring
Developed by IBM, Token Ring, is
standardized to IEEE 802.5.
|
Networking ARC net
Topology is star and bus or a mixture.
|
Netwqrking Apple Talk
AppleTalk Topology is bus.
|
Networking FDDI
The Fiber Distributed Data Interface (FDDI) standard is ANSI X3T9.5 .
|
Networking IPX/SPX
IPX/SPX is a routable protocol and can be used for small and large networks.
|
Networking NetBEUI
In order to properly describe NetBEUI, the
transport protocol sometimes used for Microsoft networking.
|
Networking Apple Talk Protocols
AppleTalk is the architecture used on with
Apple brand computers and is a suite of protocols for networking Apple
computers.
|
Networking SNA
System Network Architecture (SNA) by IBM
is a suite of protocols mainly used with IBM mainframe and AS/400
computers.
|
Networking Others
Other Topics.
|
Networking Simple Routing
This section will explain routing in simple terms with some simple standard rules.
|
Networking More Complex Routing
The 192.168.1.x network is changed to 192.168.x.x and gateway B's address is changed to 192.168.10.1.
|
Networking IP Masquerading
IP masquerading is a form of network address translation.
