Papyrus • Papyrus is a thick paper-like material produced from the pith of the papyrus plant, Cyperuspapyrus, a wetland sedge that was once abundant in the Sudd of Southern Sudan along with the Nile Delta of Egypt. Papyrus is first known to have been used in ancient Egypt, but it was also used throughout the Mediterranean region. Ancient Egyptians used this plant as a writing material and for boats, mattresses, mats, rope, sandals, and baskets.
Communication drums and horns • Developed and used by cultures living in forested areas, drums served as an early form of long distance communication, and were used during ceremonial and religious functions • The alphorn or alpenhorn or alpine horn is a labrophone, consisting of a wooden natural horn of conical bore, having a wooden cup-shaped mouthpiece, used by mountain dwellers in Switzerland and elsewhere. Similar wooden horns were used for communication in most mountainous regions of Europe, from the French Alps to the Carpathians.
Couriers • A courier delivers messages, packages, and mail. Couriers are distinguished from ordinary mail services by features such as speed, security, tracking, signature, specialization and individualization of express services, and swift delivery times, which are optional for most everyday mail services. As a premium service, couriers are usually more expensive than standard mail services, and their use is typically restricted to packages where one or more of these features are considered important enough to warrant the cost.
Heliograph • A heliographis a wireless solar telegraph that signals by flashes of sunlight (generally using Morse code) reflected by a mirror. The flashes are produced by momentarily pivoting the mirror, or by interrupting the beam with a shutter. The heliograph was a simple but effective instrument for instantaneous optical communication over long distances during the late 19th and early 20th century. Its main uses were military, survey and forest protection work. Heliographs were standard issue in the British and Australian armies until the 1960s, and were used by the Pakistani army as late as 1975.
Newspaper • A newspaper is a periodical publication containing news regarding current events, informative articles, diverse features, editorials, and advertising. It usually is printed on relatively inexpensive, low-grade paper such as newsprint. By 2007, there were 6,580 daily newspapers in the world selling 395 million copies a day. The late 2000s-early 2010s global recession, combined with the rapid growth of web-based alternatives, caused a serious decline in advertising and circulation, as many papers closed or sharply retrenched operations
Paper • Paper is a thin material produced by pressing together moist fibers, typically cellulose pulp derived from wood, rags or grasses, and drying them into flexible sheets. This later on replaced papyrus and became the modern way of writing.
Pens • A penis a writing implement used to apply ink to a surface, usually paper, for writing or drawing. Historically, reed pens, quill pens, and dip pens were used, with a nib dipped in the ink. It became highly useful for writing on paper to make letters for communication
European Printing Press • In rapid succession, printing presses were set up in Central and Western Europe. Major towns, in particular, functioned as centers of diffusion (Cologne1466, Rome 1467, Venice 1469, Paris 1470, Cracow 1473, London 1477). In 1481, barely 30 years after the publication of the 42-line Bible, the small Netherlands already featured printing shops in 21 cities and towns, while Italy and Germany each had shops in about 40 towns at that time. According to one estimate, "by 1500 1000 printing presses were in operation throughout Western Europe and had produced 8 million books."
Pencils • A pencil is a writing implement or art medium usually constructed of a narrow, solid pigment core inside a protective casing. It is an alternative to pens.
Maritime Flags • A maritime flag is a flag designated for use on ships, boats, and other watercraft. Naval flags are considered important at sea and the rules and regulations for the flying of flags are strictly enforced. The flag flown is related to the country of registration: so much so that the word "flag" is often used symbolically as a synonym for "country of registration"
Semaphore Lines • A semaphore telegraph, optical telegraph, shutter telegraph chain, Chappe telegraph, or Napoleonic semaphore is a system of conveying information by means of visual signals, using towers with pivoting shutters, also known as blades or paddles. Information is encoded by the position of the mechanical elements; it is read when the shutter is in a fixed position
Typewriter • A typewriter is a mechanical or electromechanical machine for writing in characters similar to those produced by printer's type by means of keyboard-operated types striking a ribbon to transfer ink or carbon impressions onto the paper. Typically one character is printed per keypress. The machine prints characters by making ink impressions of type elements similar to the sorts used in movable type letterpress printing.
Telegraph • Telegraphyis the long-distance transmission of textual (as opposed to verbal or audio) messages without the physical exchange of an object bearing the message. Thus semaphore is a method of telegraphy whereas pigeon post is not.
Telephone • A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are not in the same vicinity of each other to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user.
Radio • Radio is the wireless transmission of signals through free space by electromagnetic radiation of a frequency significantly below that of visible light, in the radio frequency range, from about 30 kHz to 300 GHz. These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.
Computer • A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.
Signal Lamps • A signal lampis a visual signaling device for optical communication (typically using Morse code). Modern signal lamps are a focused lamp which can produce a pulse of light. In large versions this pulse is achieved by opening and closing shutters mounted in front of the lamp, either via a manually operated pressure switch or, in later versions, automatically.
Television • Television, or TVis a telecommunication medium for transmitting and receiving moving images that can be monochrome (black-and-white) or colored, with or without accompanying sound.
Computers and text editors • A text editor is a type of program used for editing plain text files. • Text editors are often provided with operating systems or software development packages, and can be used to change configuration files and programming language source code.
Computer networking • A computer network or data network is a telecommunications network that allows computers to exchange data. In computer networks, networked computing devices (network nodes) pass data to each other along data connections. The connections (network links) between nodes are established using either cable media or wireless media. The best-known computer network is the Internet.
Internet • The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks.
1G Networks • 1G (or 1-G) refers to the first-generation of wireless telephone technology, mobile telecommunications. These are the analog telecommunications standards that were introduced in the 1980s and continued until being replaced by 2G digital telecommunications. The main difference between two succeeding mobile telephone systems, 1G and 2G, is that the radio signals that 1G networks use are analog, while 2G networks are digital.
2G Networks and 2.5 Networks • 2G (or 2-G) is short for second-generation wireless telephone technology. Three primary benefits of 2G networks over their predecessors were that phone conversations were digitally encrypted; 2G systems were significantly more efficient on the spectrum allowing for far greater mobile phone penetration levels; and 2G introduced data services for mobile, starting with SMS text messages. 2G network allows for much greater penetration intensity. 2G technologies enabled the various mobile phone networks to provide the services such as text messages, picture messages and MMS (multi media messages). All text messages sent over 2G are digitally encrypted, allowing for the transfer of data in such a way that only the intended receiver can receive and read it.
3G Networks • 3G, short for third Generation, is the third generation of mobile telecommunications technology. • 3G telecommunication networks support services that provide an information transfer rate of at least 200 kbit/s. However, many services advertised as 3G provide higher speed than the minimum technical requirements for a 3G service. Later 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. • 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV.
4G Networks • In telecommunication systems, 4G is the fourth generation of mobile phone mobile communication technology standards. It is a successor to the third generation (3G) standards. A 4G system provides mobile ultra-broadband Internet access, for example to laptops with USB wireless modems, to smartphones, and to other mobile devices. Conceivable applications include amended mobile web access, IP telephony, gaming services, high-definition mobile TV, video conferencing, 3D television, and cloud computing.
