Communication Techniques Details & Overviews

Contacting History Ever since ancient times one could have imagined the world as a very difficult place to travel or communicate, or to communicate messages and information from one region to another, it takes a long time to send a message. In the present reality, after the modern technological renaissance, the world has truly become a small village, quite different from the past: from pigeons, horses and camels to modern telecommunications technologies that are no longer indispensable. The modern communication of modern communication techniques is what is wired and what is wireless, both of which are ways of transmitting data of all kinds (voice, video, etc.).


Smartphones have swept the world markets and become widespread die Smart phones have many features, including Internet browsing, user email synchronization, browsing of all document files, and a variety of features that are not available in any mobile device. On a full keyboard to help the user write,  and a popular operating system, such as Android, iOS, Blackberry, etc.The features were only present in computers, both desktop and desktop Bluetooth is a device that emerged in late 1994, in which two electronic devices (mobile phones, computers, or even modern printers) communicate without any wires or physical or sensory devices connecting them.


 This system sends data and files between these two devices at speeds up to 24 megabits per second, with a distance of up to 200 feet. This makes it easier for the user to connect with wires or remove the memory chip and connect it to the computer, This technology has the following Connect your cell phone with headphones For the head. Connect the printer with the PC. Connect your cell phone with your PC. Connect mouse and keyboard with PC. Connect the cell phone with the audio equipment in the car. This technology allows the rest of the home appliances to be connected to a computer or mobile phone. Wi-Fi technology has been deployed in wireless networks, enabling the user to transfer data but with a greater distance than Bluetooth technology offers.


It also allows Internet access without the need to connect the tablet, Mobile phone, or even without any type of wired Internet connection, which means great mobility and flexibility to move anywhere in the home, inside the university, or wherever wireless Internet is available. Wi-Fi is a sophisticated technology that allows the Internet to be deployed and sent wirelessly in the air, unlike the wired Internet, which requires the Internet cable connected between the distributor and the computer or the receiver, thus hampering the user's freedom of movement.


The technology is based on the Internet service connected to a wireless access point,  which in turn distributes Internet in the air in the form of waves picked up by neighboring devices. WiMAX Global Interoperabilit y for Microwave Access is a technology that distributes wireless Internet over a certain range, covering a radius of 50 km, while the standard Wi-Fi is 30 meters, and it does not need to be used at the same level as towers The cost will be lower for the consumer, since there is no need to extend the wiring to each house in the city, which will reduce the material cost, but this will not be at the expense of quality of service, but quite the opposite, the speed of this technology may reach Point of transmission to 70 Mbps The second generation is a doubling of Wi-Fi speed of up to 54 megabits per second. Third generation 3G is a new technology in wireless internet, Mobile phones, to connect to the Internet from anywhere through specialized towers distributed to certain areas by the telecommunications company. 



This technology is an alternative to older communication devices, such as the second generation (in English: 2G), 3G service faster and more coverage.  is a generation-based technology, which appeared in 2009, successor to the technology of the third generation.  Landline phone is a telephone based on metallic wire or fiber optic transmission of sound waves  This technique was the most widely used in homes, but with the emergence and development of mobile phones and telecommunications companies has been less used, but still used in institutions and offices, but some companies are resorting to alternative ways and means. Digital Subscriber Line Digital Subscriber Line (ING) technology (DSL) are wired to connect to the Internet, and digital services are connected via the telephone line. This is bad for the technology, as it can only be used when a landline phone is available. [25] Normal conditions (such as the status of home contributions) to a maximum of 100 megabits per second.
