The History Of Blogger

Blogger was first launched on August 23, 1999.  It was created by Pyra Labs. Blogger is one of the earliest blog publishing tools.  It has been credited for helping to popularize the format.   At first Blogger was entirely free and there was no income model.  When Pyra Lab’s money was diminished, the employees worked without pay for weeks, even months.  This caused a lot of employees to leave the company. Evan Williams, who is the co founder of Blogger, ran the company solely by himself after the loss of income.  He then was lucky to seal an investment by Trellix. Soon after, advertising started supporting Blogger, and Blogger Pro emerged.

Story of Intel

Intel began in 1968. It was founded by Gordon E. Moore who is also a physicist and chemist. He was accompanied by Robert Noyce, also a fellow physicist and co-creator of integrated circuitry, after they both had left Fairchild Semiconductor. During the 1980’s Intel was run by a chemical engineer by the name of Andy Grove, who was the third member of the original Intel family. Many other Fairchild employees participated in other Silicon Valley companies. Andy Grove today is considered to be one of the company’s essential business and strategic leaders. As the 1990’s concluded, Intel had become one of the largest and by far the most successful businesses in the entire world. Intel has gone through many faces and phases. In the beginning Intel was set apart by its ability primarily to create memory chips or SRAM.

The History Of IBM

The History of IBM goes back further than the development of computers. It was originally a Tabulating Machine Company founded in 1896 by Herman Hollerith. It specialized in developing punched card data processing equipment. The patent for this technology was initially applied for in 1884. It began as a means for Hollerith to meet the demands in tabulating the 1890 Census. Punch cards introduced in 1896 laid the foundation for generations of equipment which would one day be known as IBM. The business was sold to Charles Flint in 1911 for 2.3 million dollars of which he received 1.2 million dollars to create Computing Tabulating Recording Corporation or CRT. Incorporation took place on June 16, 1911 in Endicott, New York.

Story Of Dell

Dell, Inc, which was ranked the 25th largest company on the Fortune 500 list by Forbes magazine, began its cosmic rise in 1984 when Michael Dell used a mere $1000 dollars to found PC’s Limited. Working in a college dorm room at the University of Texas, Michael Dell had a goal to produce IBM compatible computers from stock components to suit individual customer needs.

Story of Google

Everyone knows the name Google. Whether young or old, computer smart or not this name will pop up in any conversation about computers. Google has created some very impressive milestones of its time and continues to grow rapidly every day.  It all started when Larry Page and Sergey Brin met in Stanford. Larry was 22 and a graduate of University of Michigan was there considering attending the school. And low and behold Sergey, who was 21, was there to show him around. Talk about a match made in heaven!

Story of Wordpress

WordPress is a blog template system that was launched in 2001 as a single bit of code used to enhance the composition of writing. Since then it has become the largest self-hosted blogging tool in the world. Millions of people on a vast number of websites use it every day. WordPress was designed due to the desire and need for a well-designed and structured publishing system using PHP and MySQL. It was created out of necessity as users demanded a high performance system. With thorough research on the aspects needed and demanded by writers, WordPress evolved into a project, which has a large following and user satisfaction. The creation of WordPress has taken the world by storm.

VoIP phones

VoIP phone

VoIP means Voice over Internet Protocol. VoIP phones (or Digital Phones) send voice data in packets over the IP layer. The services they provide are typically the same as the normal phones but the underlying network and the technology are different.

* It might be a dedicated device (like the traditional handset) using IP connection.
* It can also be a normal phone connected to the network through a telephony adapter (TA).
* Else it can be a softphone.

How does VoIP work?

* When you speak at the handset or a mike or a microphone, your voice generates electrical signals inside the gadget. These are analog signals i.e. the voltage level can take up any value within a range.

* The analog signal is converted to a digital signal using an algorithm implemented by the device you are using. It can be a stand-alone VoIP phone or a softphone running on your PC. If you are using an analog phone, you will need a Telephony Adapter (TA) for this purpose. The digitized voice is arranged in packets (i.e. collection of bytes) and sent over the IP network.

* The data is channeled through gateways and servers to the destination. If the called number is on the PSTN, the server opens a connection to the PSTN and routes your call there.

* While going to the PSTN or at the end device of a VoIP connection, the voice is again brought back to its analog form so that it is perceptible to a human ear.

Introduction to VoIP

What is VoIP?

VoIP is the short form of Voice over Internet Protocol. It is also called IP Telephony, Internet telephony or Digital Phone. It utilizes the IP network (Internet or intranets) for telephone conversations. The service it provides is similar as that of normal landline phones but generally offers a cheaper solution. It has some added advantages and as any other service, it faces some challenges too.

How is this useful? VoIP can turn a standard Internet connection into a way to place free phone calls. The practical upshot of this is that by using some of the free VoIP software that is available to make Internet phone calls, you're bypassing the phone company (and its charges) entirely.

Public switched data network

A public switched data network (PSDN) is a publicly-available packet-switched network, distinct from the PSTN.

Originally this term referred only to Packet Switch Stream (PSS), an X.25-based packet-switched network, mostly used to provide leased-line connections between local area networks and the Internet using permanent virtual circuits (PVCs). Today, the term may refer not only to Frame Relay and Asynchronous Transfer Mode (ATM), both providing PVCs, but also to Internet Protocol (IP), GPRS, and other packet-switching techniques.

PSTN (Public Switched Telephone Network)

Definition: PSTN is the global collection of interconnects originally designed to support circuit-switched voice communication. The PSTN provides the traditional Plain Old Telephone Service (POTS) to residences and many other establishments. Parts of the PSTN are also utilized for DSL, VoIP and other Internet-based network technologies.

Switching in computer networks

A network switch or switching hub is a computer networking device that connects network segments.
The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (Layer 3) and above are often referred to as Layer 3 switches or multilayer switches. The term network switch does not generally encompass unintelligent or passive network devices such as hubs and repeaters.

Linear Variable Differential Transformers (LVDTs)

What is Linear Displacement Measurement?

Linear displacement is movement in one direction along a single axis. A position or linear displacement sensor is a device whose output signal represents the distance an object has traveled from a reference point. A displacement measurement also indicates the direction of motion.  A linear displacement typically has units of millimeters (mm) or inches (in.) and a negative or positive direction associated with it.

Microturbines

Introduction and Summary

Microturbines are small electricity generators that burn gaseous and liquid fuels to create highspeed rotation that turns an electrical generator. Today’s microturbine technology is the result of development work in small stationary and automotive gas turbines, auxiliary power equipment, and turbochargers, much of which was pursued by the automotive industry beginning in the 1950s. Microturbines entered field testing around 1997 and began initial commercial service in 2000.
