Development and Evolution of Cellular Technology

Phone from the last few years has been along lines of excellence in mobile evolution is slow since the brick "first" was released in 1983. A huge jump in the time line is the case when the Apple iPhone came out in June 2007. Apple iPhone is the first of its kind to incorporate multi-touch technology. Multi-touch is a technology where the device can track the actions of more than one finger at once on the touch screen.

The original iPhone 3G and both are equipped with quad band GSM / EDGE, but newer models are also equipped with a 3G tri-band HSDPA / UMTS 850/1900/2100. Model 3G allows faster data transfer for web browsing experience smoother and better Network. Wi-Fi is also standard on the original and 3G models, and the device supports Bluetooth 2.0 EDR. The increase in first-generation cell phone towers and Wi-Fi triangulation in the Maps application, including the 3G model A-GPS for navigation is very precise.

The iPhone is designed as a slab, where almost the entire face of the phone screen. This screen is spectacular, not only 3.5 inches, a lot of room for viewing movies, pictures, and web pages, but it has a pixel density of 160 ppi (pixels per inch). Below the screen is the single, "Home" button, which will return the user to the main screen with a single thrust. Little touches are not negligible in these devices, such as the inclusion of an ambient light sensor to adjust screen brightness automatically.

There is also a distance sensor so that when the phone is raised to the face, back light turned off, and the input deliberately ignored. At the rear, an integrated 2.0 megapixel camera on the upper left corner. To interact with the device, multi-touch functionality allows users to "movies" page or image left / right with a quick dragging movement. Zoom in / out picture or a Web site that involves placing two fingers in the desired location, then pass it either apart or closer together with a "pinch". iPhone also received a physical orientation sensing via the 3-axis accelerometer that detects the phone in portrait or landscape mode, so for the video screen, "Cover Flow" interface on the music, and web browsing screen.

To enable all features, the iPhone is running, fully complete, the original OS X operating system, only the driver is not required and the code is stripped out. It supports phones with the tried and tested Unix-based architecture and broad support for third party applications via the SDK. The iPhone was originally sent to the calendar, notes, YouTube, photos, cameras, weather, stocks, calculators, and application maps. Apple has added the application, including Wi-Fi iTunes music store, a custom ringtone through iTunes, and Google Maps applications increased. With OS 2.0, the ability is much more have been added to your phone, including corporate support, geotagging, and App Store. App Store allows users to download a free app or paid natives anywhere that allows instant messaging, Twitter, and Facebook support, to name a few.

Technological means of communication by computer network

Computer Network is a system consisting of computer and other network devices that work together to achieve a common goal. The purpose of computer networks, among others :

a. Share resources, such as shared use of printers, CPU, memory, hard drive.

b. Communication, examples of electronic mail, instant messaging, chat

c. Access to information, for example web browsing.

In order to achieve the same goal, every part of the computer network to request and provide services (service). The party requesting the service are called clients (client) that provides services and called the waiter (server). This architecture is called client-server system, and used in almost all computer network applications.

Work Process Computer

Computer is an electronic device that is able to manage data and produce information. All entries received by the computer is called data. Such data may include text, figures, graphs, diagrams, and so forth. Furthermore, the data contained in computer processed using the programming language.

All incoming data will be converted into a binary number that can be read computer virgin. The data has been processed and then converted into a computer information. Information itself has meaning as an arrangement of data is arranged in such a way that has meaning to human understandable.

If we sort the computer information, it will get the velocity of information processing. Turnaround process is started from the user information, input, cpu, output and return to the user again.

Radio and Telecommunications Equipment Television with Electromagnetic waves

RADIO

Radio is a technology that allows pegiriman signal by modulating electromagnetic waves. These waves pass (spread) through the air and the vacuum space, because these waves do not require a transport medium. Radio waves are a form of electromagnetic radiation and is formed when the object is accelerated by the electric charge contained in the frequency Radio frequency (RF) in the electromagnetic spectrum. These waves vary in the range of 10 hertz up to several giga hertz. Radiation lektromagnetik moved by electric and magnetic oscillations. When radio waves through the cable, the oscillation of electric and magnetic fields can affect the alternating current and voltage in the cable. Radio waves can be transformed into audio or other signals that can create information.

TELEVISION

Television is a broadcast picture tentacle. Televise word comes from the word tele and vision, who have their own meaning far (tele) and visual (Vision) so that means melihar television from a distance. Equated with the discoverer discoverer televise the wheel, because it can change the world civilization. In Indonesia "Television" sometimes informally referred to tivi, TV, or Tipi.

The discovery of television involve many parties, inventor and innovator, both individually and corporately. Television is a mass work from year to year. Inventor of television would not be separated from the inventor's legal basis of electromagnetic wave that was invented by Joseph Henry and Michael Faraday (1831) who started the era of electronic communication.

Telecommunications Equipment Telephone electronic distance

The word telephone comes from the word tele (far) and Phone (voice). So, the phone is the remote communication device via an electrical signal which is usually a sound. Initially, the inventor of the telephone was Alexander Graham Bell made ​​the first phone in boston, Massachusetts in 1876, however, Italian inventor Antonio Meucci had invented the telephone in 1849. therefore, in September 2001, Meucci was officially accepted as the creator of the telephone by the American Congress, not Alexander Graham Bell.

The phone can be distinguished by three types, namely:

1. Conventional phones are used by way of playing

2. Conventional phones are used by way of reduced

3. Cellular Phone / Mobile.

Along with the rapid technological, has now developed a cell phone. Cell phone, or better known as mobile (HP) also referred to as a mobile phone or cell phone is an electronic telecommunications device that has the same basic capabilities with a conventional phone, but can be taken anywhere (Portable) and need not be connected to the telephone network using cable (wireless; wireless). Indonesia currently has two wireless telephone network, the GSM (Global System for Mobile) and CDMA (Code Division Multiple Access).

Mobile phones in addition to work to make and receive phone calls, generally it also serves to send and receive short messages (Short Message Service: SMS), phone calls are more expensive cameras often add features and Internet service (Wireless Application Protocol: WAP and General Packet Radio Services; GPRS). There is also the provision of mobile telephone services in several countries that provide third generation services (Third-Generation; 3G), adding a videophone and television services on their mobile phones online.

The Childs information with the Telecommunication Technology

Information Technology will subsystem of an information system, the system can produce useful information. Information technology-supported communication technologies enable the deployment of information quickly and accurately all over the world. Information and communication technologies are always associated with advances in Computer Technology. During its development, communication technology has allowed for long-distance communication is called "Telecommunications". In this case the functions and principles of telecommunications, computer technology work processes and other support equipment.

Telecommunication

The word comes from the telecommunications tele (far) and communication (communication). So telecom is a form of remote communication to send messages from one place to another, and usually take place in two directions. Telecommunications includes all forms of electronic communication over long distances, including:

• Radio

• Television

• Telephone

• Computer Network.
