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.

This section provides various tutorials on computer networking, a domain that spans various geographies, on which the Internet is born. The articles include ISO OSI model, computer network planning and implementation, RFID standards, spread spectrum communications, IPv6 and many more.

The article provides an in-depth view of keeping time and frequencies in case of satellite chain. When communicating over satellite system, it becomes important to keep the communication coherent as the space segment is usually above 36,000 Kilometers and there is a few seconds of delay between transmission and reception of the signals. By knowing exactly how much delay has happened, we can compensate for the same.

The article provides a detailed procedure for noise figure measurements. Noise figure measurement is one of the most important parameter in the receive chain of the satellite - to - ground station link. The signals received at the antenna are very weak and requires a low noise amplifier to keep the noise below the threshold level.

The section provides various tutorials on RF test and measurements. These include, co-axial insertion and return loss measurement, spectrum analyzer measurements, and noise figure measurements. An article on coax cable construction and assembly is also provided.

This section provides several tutorials on Satellite Communications, including satellite systems, link budgeting, satellite pointing angle calculator, and other related topics.

The article provides a basic introduction with a couple of coding examples using html5, a widely used web programming language these days. Responsive design is popular for compatibility with different types of devices.

The article provides a detailed procedure as to how to design and develop activex controls using Visual Basic. ActiveX controls, though became a little obsolete with the advent of .net based framwork, is still used widely.

The article provides step by step procedure for programming with SQL using MySQL and visual basic. As you might be knowing, VB.net and MySQL are powerful combination to develop programs for commercial use.

The section provides various tutorials on software and database programming including VB.net, SQL programming for MySQL, etc., and web development using HTML5 and JavaScript. A couple of programming examples are given for drag and drop and activeX development.

The article describes various stages of computer networks such as planning, designing and implementation. With the advent of Internet, computer networks are widely used for accessing the Internet and local networks (such as LANs and intranets).

TCP/IP, short for Transmission Control Protocol/ Internet Protocol is the protocol of choice for Internet communications. The article describes layered approach to the protocol stack and relates to the 7-layer OSI protocol.

A tablet personal computer (tablet PC) is a pocket computer equipped with a touch screen for input, and running an OS such as android or iOS. Tablet PC screen size is usually in the range of 7" up to 11". After 11 inches, it usually comes into small size laptop and hardly fit your packet. Lower than 7inches, smart phones are popular. The article describes the components of a tablet PC, advantages and disadvantages, and how it compares with laptop and smart phones.

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.

The web page provides an article on satecom fundamentals, including how the satellite communications take place, the various segments of communication, viz ground segment(s) and space segment.
