What is the Full Form of SMS?
SMS is the abbreviated form of Short Message Service. This widely used communication technology has become an integral part of our daily lives, allowing us to send brief text messages across mobile networks.
What is Short Message Service?
Short Message Service, commonly known as SMS, is a standardized communication protocol that enables the exchange of short text messages between mobile devices. It allows users to send and receive messages of up to 160 characters in length, including letters, numbers, and symbols.
Origin and Development of Short Message Service
The concept of SMS has an interesting history:
- Early 1980s: The idea of text messaging was first introduced for mobile devices.
- December 1982: The GSM (Global System for Mobile Communications) standard was adopted, which included provisions for text messaging services.
- 1984: Friedhelm Hillebrand and Bernard Ghillebaert developed the SMS concept during a Franco-German collaboration.
- 1992: The first SMS was sent over the Vodafone GSM network in the UK.
- 1993: Nokia introduced the first mobile phone supporting user-sending of SMS texts.
The primary goal behind SMS was to utilize existing signaling paths in telecommunications networks to transmit messages efficiently.
How does Short Message Service work?
SMS operates on cellular networks, utilizing the control channels that are already in place for managing voice calls. When a user sends an SMS:
- The message is sent to a Short Message Service Center (SMSC).
- The SMSC forwards the message to the recipient's device.
- If the recipient's device is unavailable, the SMSC stores the message and attempts delivery later.
This store-and-forward mechanism ensures that messages are delivered even if the recipient's phone is temporarily unreachable.
Types of Short Message Service
While SMS is generally uniform, there are a few variations:
- Standard SMS: The most common type, limited to 160 characters.
- Concatenated SMS: Allows longer messages by splitting them into multiple parts.
- Flash SMS: Appears directly on the recipient's screen without being stored in the inbox.
- Silent SMS: Used for location tracking, doesn't display any message to the recipient.
