INFORMATION COMMUNICATION TECHNOLOGY GADGETS
An information communication technology gadget involves the technology and the applications which are used in creating communication, transmission and storage devices. There are many ICT gadgets which are used in communication technology. Some of them are:
1. GLOBAL SYSTEM FOR MOBILE (GSM): Global system for mobile communication is an ICT gadget and second generation digital technology. GSM is top-class standard gadget relied on by millions of people worldwide. Today’s GSM is a huge success wireless technology and an unprecedented story of global achievement. It is approximated that 80 percent of the world used GSM technology while making wireless calls.
2. FAX MACHINE: The fax machine is a device that can send or receive picture and text over telephone line. The idea of fax machine has been around since 1842, when Alexander Bain invented a machine capable of receiving signals from telegraph wire and translating them into images on paper. However, fax machine did not become popular until mid 1980s. A fax machine consist of an optical scanner for digitizing image on paper, a printer for printing incoming fax message and a telephone for making the connection.
3. TELEPHONE: Telephone is an electronic telecommunication device used for transmitting and receiving sounds. The most basic function of a telephone is to allow communication between two points, whether they are near or far from each other.
4. COMPUTER SYSTEM: The computer system will include the computers along with software and peripherals devices that are necessary to make the computer function. Every computer system requires an operating system.
5. PAGER: A Pager is a small telecommunication device that receives and sends alert signals or short messages. It is the size of a pocket calculator and has built in miniature keyboard and LCD screen that can display several lines of text.
6. TELEX: Telex is a communication system consisting of small typewriters connected to a telephonic network to send and receive signals or message.

Creating and Sending Messages Using GSM
GSM is the most popular standard for mobile phones in the world. Deployed first in year 1991, GSM system is a second generation (2G) cellular phone technology. In over twenty years of development, GSM has been continually evolved to provide platform to deliver broad range of mobile services as per market demands. Examples of newer version of this standard are GPRS, Enhanced data rates for GSM evolution (EDGE), 3G, etc. that in addition to voice telephony supports applications with higher data rates like mobile internet, video calls and mobile TV. Long-term evolution (LTE), marketed as
4G LTE, is now at the door step and claims to increase capacity and speed of mobile communication network drastically.
SMS is a text messaging service available on GSM networks. It provides a mechanism for transmitting short message to and from a wireless device registered in a GSM network. SMS has its first commercial deployment in 1993.
Short messaging entity (SME) represents an entity that may receive or send a SMS. SME may be located in either fixed network, a mobile station (MS) or another service center. Typical example of SME can be a mobile handset or a GSM modem. When SME sends out an SMS, short message service center (SMSC) relay this data to SMS-gateway mobile switching center (SMS-GMSC). SMS-GMSC accesses the home location register (HLR) to search the current location of destination number and send the route information to mobile switching center (MSC).
In order to create SMS using GSM tap on the message icon, input the recipient's number, go to the content box and type the content of your SMS and send.
