Tutorials On Computers And Networking - Mpls, Motherboards, OSI Models, TCP/IP & Others

Introduction to MPLS

This article gives introduction to MPLS. It also discusses how MPLS works and implementation of MPLS on Cisco and Juniper router with some examples. It also lists some advantages of using MPLS

Computer Motherboard Explained

The tutorial provides a complete coverage of typical desktop computer motherboard and its components. Important components of a motherboard include memory, processor, chipset, and connectors (used for FDD, HDD, CDROM, etc.). Different terms used in the motherboard have also been explained.

ISO OSI Model - Tutorial

ISO Open Systems Interconnection (OSI) model is one of the most widely read about topic in the area of systems connectivity. The OSI layer consists of 7 layers, viz Application, Presentation, Session, Transport, Network, Datalink, and Physical. Each of these layers have been explained in detail. Relationship between OSI model and network devices has been given.

Introduction to TCP/IP

TCP/IP has come to prominence with the emergence of Internet. The Internet uses TCP/IP protocol for communication. The article provides a review of network technologies, TCP/IP layering, IP addressing, and how the packets are routed through the Internet. Various IP protocols such as DNS, FTP, Telnet, and ICMP have been discussed.

Computer Networks: Planning, Design, Implementation

The article is primarily intended for people intending to design or implement a computer network. Various topics covered include network planning, implementation, and security considerations. Wireless networking and IP telephony topics have also been discussed.

Juniper Systems^® and Cisco^® Routers - A beginner's Guide

Network administration has become a main line of profession after the advent of internet and intranets. Though there are several manufacturers that produce network gear, Cisco and Juniper are two front line producers of networking equipment. Cisco equipment uses IOS whereas Juniper equipment uses Junos operating system. The article discusses and compares both the Operating Systems.

WiMAX: Wireless Broadband

WIMAX is used for accessing wireless broadband Internet over a wide geographical areas. Its counterpart Wi-Fi is limited to an operational radius of a few hundreds of feet whereas WIMAX can operate over several kilometers of radius. The article discusses specifications and advantages of using WIMAX, and compares it with WIFI.

RFID � Standards, Application, and Advantages

The article provides an introduction to passive and active RFID systems. It also discusses RFID standards, manufacturers, and implementation of RFID systems. A review of RFID test labs has been provided.

Spread Spectrum Communications: Fundamentals, Applications, and Products

Spread Spectrum Communications was initially used for military and encrypted communications. However, the technology has developed and now widely used for commercial, space, and industrial applications. The article discusses types of SS communications, manufacturers, and products. Glossary of terms and references has been provided.

Flash Memory: Theory and Applications

Flash memory is a type of mass storage like Hard Disk Drive (HDD) but uses different technology for storage and retrieval of information. The theory behind Flash memory, and the characteristics of Flash memory has been discussed. Typical applications of this type of memory have also been provided.

Computer Printers and Scanners - A Review

Printers are the most widely used output devices that have evolved over a period of time. The article starts with impact printers that are almost extinct now, and goes on to cover the theory and operation of laser printers. Similarly, scanners are increasingly used for inputting text and graphic images in to the computer, either for local processing and storage or for communicating to a remote system. Common problems with printers and scanners, and the diagnostic tools required for troubleshooting have also been discussed.

A tutorial on IPv6

Internet Protocol Version 6 (IPv6) is the next generation Internet Protocol (IP) for Internet Networking, which is often treated as successor to Internet Protocol Version 4 (IPv4). This article includes addressing basics, Loop Back address, Header information, Features of IPv6 and differences between IPv4 and IPv6.
