Text Message
Text messaging, or texting, is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile phones, tablet computers, smartwatches, desktop computer, desktops/laptops, or another type of compatible computer. Text messages may be sent over a cellular network or may also be sent via Satellite phone, satellite or Internet connection. The term originally referred to messages sent using the SMS, Short Message Service (SMS) on mobile devices. It has grown beyond alphanumeric text to include multimedia messages using the Multimedia Messaging Service (MMS) and Rich Communication Services (RCS), which can contain digital images, videos, and sound content, as well as ideograms known as emoji (Smiley, happy faces, sad faces, and other icons), and on various instant messenger, instant messaging apps. Text messaging has been an extremely popular medium of communication since the turn of the century and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SMS Composition On Feature Phone
Short Message Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile phones exchange short text messages, typically transmitted over cellular networks. Developed as part of the GSM standards, and based on the Signalling System No. 7, SS7 signalling protocol, SMS rolled out on digital cellular networks starting in 1993 and was originally intended for customers to receive alerts from their Mobile network operator, carrier/operator. The service allows users to send and receive text messages of up to 160 characters, originally to and from GSM phones and later also Code-division multiple access, CDMA and Digital AMPS; it has since been defined and supported on newer networks, including present-day 5G ones. Using SMS gateways, messages can be transmitted over the Internet through an Short Message service center, SMSC, allowing communication to compute ...

Telephone Call
A telephone call, phone call, voice call, or simply a call, is the effective use of a connection over a telephone network between the calling party and the called party. Telephone calls are the form of human communication that was first enabled by the development of the telephone and several inventions in the mid- to late-19th century. Initial technology involved point-to-point electrical wire connections between telephone installations, until centralized exchanges evolved where Switchboard operator, telephone operators established each interconnection manually at a telephone switchboard after asking the calling party for their call destination. After the invention of automatic telephone exchanges in the 1890s, the process became increasingly automated, eventually leading to the widespread adoption of digital exchanges in the second half of the 20th century, including the transition to wireless communication via mobile telephone networks and cellular networks.

ALOHAnet
ALOHAnet, also known as the ALOHA System, or simply ALOHA, was a pioneering computer networking system developed at the University of Hawaii. ALOHAnet became operational in June 1971, providing the first public demonstration of a wireless packet data network. The ALOHAnet used a new method of medium access, called ''ALOHA random access'', and experimental ultra high frequency (UHF) for its operation. In its simplest form, later known as Pure ALOHA, remote units communicated with a base station (Menehune) over two separate radio frequencies (for inbound and outbound respectively). Nodes did not wait for the channel to be clear before sending, but instead waited for acknowledgement of successful receipt of a message, and re-sent it if this was not received. Nodes would also stop and re-transmit data if they detected any other messages while transmitting. While simple to implement, this results in an efficiency of only 18.4%. A later advancement, Slotted ALOHA, improved the effi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reich
( ; ) is a German word whose meaning is analogous to the English word " realm". The terms and are respectively used in German in reference to empires and kingdoms. In English usage, the term " Reich" often refers to Nazi Germany, also called "the Third Reich". The term (sometimes translated to "German Empire") continued to be used even after the collapse of the German Empire and the abolition of the monarchy in 1918. There was no emperor, but many Germans had imperialistic ambitions. According to historian Richard J. Evans: The term is used for historical empires in general, such as the Roman Empire (), Persian Empire (), and both the Tsardom of Russia and the Russian Empire (, literally " Tsars' realm"). , the name used for Austria today, is composed of and which, literally translated, means "Eastern Realm". The name once referred to the eastern parts of the Holy Roman Empire. In the history of Germany specifically, it is used to refer to: * the early medieva ...

Reichspost
''Reichspost'' (; "Imperial Mail") was the name of the postal service of Germany from 1866 to 1945. ''Deutsche Reichspost'' Upon the outbreak of the Austro-Prussian War of 1866 and the break-up of the German Confederation in the Peace of Prague (1866), Peace of Prague, the North German Confederation was established, instigated by the Kingdom of Prussia, Prussian minister-president Otto von Bismarck. Originally a military alliance, it evolved to a federation with the issuing of a constitution with effect from 1st July 1867. In the course of the war, Prussian troops had occupied the Free City of Frankfurt and the King of Prussia (later to become the German Kaiser, or Emperor) had purchased the remnants of the Thurn-und-Taxis Post organisation. According to article 48, the federal area of the Northern German states, ''de facto'' an enlarged Prussia, came under the united postal authority, led by director Heinrich von Stephan. With the German unification upon the Franco-Prussia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Waves
Radio waves (formerly called Hertzian waves) are a type of electromagnetic radiation with the lowest frequencies and the longest wavelengths in the electromagnetic spectrum, typically with frequencies below 300 gigahertz (GHz) and wavelengths greater than , about the diameter of a grain of rice. Radio waves with frequencies above about 1 GHz and wavelengths shorter than 30 centimeters are called microwaves. Like all electromagnetic waves, radio waves in vacuum travel at the speed of light, and in the Earth's atmosphere at a slightly lower speed. Radio waves are generated by charged particles undergoing acceleration, such as time-varying electric currents. Naturally occurring radio waves are emitted by lightning and astronomical objects, and are part of the blackbody radiation emitted by all warm objects. Radio waves are generated artificially by an electronic device called a transmitter, which is connected to an antenna, which radiates the waves. They are receiv ...

Wireless Telegraphy
Wireless telegraphy or radiotelegraphy is the transmission of text messages by radio waves, analogous to electrical telegraphy using electrical cable, cables. Before about 1910, the term ''wireless telegraphy'' was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the radio receiver, receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and radio receiver, receivers invented in 1894–1895 by Guglielmo Marconi used radi ...

Electrical Telegraph
Electrical telegraphy is point-to-point distance communicating via sending electric signals over wire, a system primarily used from the 1840s until the late 20th century. It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called '' telegraphs'', that were devised to send text messages more quickly than physically carrying them. Electrical telegraphy can be considered the first example of electrical engineering. Electrical telegraphy consisted of two or more geographically separated stations, called telegraph offices. The offices were connected by wires, usually supported overhead on utility poles. Many electrical telegraph systems were invented that operated in different ways, but the ones that became widespread fit into two broad categories. First are the needle telegraphs, in which electric current sent down the telegraph line produces electromagnetic force to move a needle-shaped pointer into position o ...

Colloquialism
Colloquialism (also called ''colloquial language'', ''colloquial speech'', ''everyday language'', or ''general parlance'') is the linguistic style used for casual and informal communication. It is the most common form of speech in conversation among persons in friendship, familial, intimate, and other informal contexts. Colloquialism is characterized by the usage of figurative language, contractions, filler words, interjections, and other informalities such as slang. In contrast to formal and professional communications, colloquial speech does not adhere to grammar and syntax rules and thus may be considered inappropriate and impolite in situations and settings where etiquette is expected or required. It has a rapidly changing lexicon and can also be distinguished by its usage of formulations with incomplete logical and syntactic ordering. Definition Colloquialism is distinct from formal speech or formal writing.colloquial. (n.d.) Dictionary.com Unabridged (v 1.1). Ret ...

Mail
The mail or post is a system for physically transporting postcards, letter (message), letters, and parcel (package), parcels. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly, with a fee on the article prepaid. Proof of payment is usually in the form of an adhesive postage stamp, but a postage meter is also used for bulk mailing. Postal authorities often have functions aside from transporting letters. In some countries, a Postal Telegraph and Telephone, postal, telegraph and telephone (PTT) service oversees the postal system, in addition to telephone and telegraph systems. Some countries' postal systems allow for savings accounts and handle applications for passports. The Universal Postal Union (UPU), established in 1874, includes 192 member countries and sets the rules for international mail exchanges as a List of ...
