Evolution of digital technology
Several significant technologies (including digital technology) have been introduced into education throughout the last century. Each of these technologies was supposed to transform teaching and learning in the most part. However, it is widely acknowledged that significant educational reorientation or modifications have not occurred. The various stages of education system digitization may be classified into three categories: Pre-digital, personal computer and internet followed by the future of digital technologies in education(S. Roxanne Hiltz, M. Turoff ,2005). While we explain these three eras, it would be a mistake to believe that this is the only way to understand the history of technology in education, as technology has always been at the forefront of human education.
The Primitive classroom
• In 1870, the Magic Lantern, a rudimentary version of a slide projector that projected images printed on glass plates, was introduced to the classroom.
•In the 1920s, radio ushered in a whole new era of education, with on-air classrooms sprouting up for any student within listening range.
• In 1930, an overhead projector was introduced, followed by a ballpoint pen in 1940 and headphones in 1950.
•In 1951, videotapes appeared on the market, ushering in a new and fascinating form of learning.
• The Skinner Teaching Machine created a teaching and testing system that reinforced right responses so that students may go on to the next session.
• The photocopier (1959) and portable calculator (1972) were the next technologies to reach the classroom, enabling for on-the-fly mass production of materials and rapid arithmetic calculations.

Personal Computers Introduction and Importance of internet:
In 1981, the first portable computer weighed 24 pounds was invented by IBM. In 1982, the Computer was named "Man of the Year," and rightly so: the groundwork for immediate learning capabilities had been built.
• When a British researcher created Hyper Text Markup Language, or HTML, in 1990, the world exploded into a frenzy of newfound research and communication methods, and when the National Science Foundation (NSF) removed restrictions on commercial use of the Internet in 1993, the world exploded into a frenzy of newfound research and communication methods.
• Apple Computer Inc. introduced the first Personal Digital Assistants (PDAs) in 1993, and computers became a part of every day, if not every minute, after that.
• Today's college students are rarely without access to digital technology: 83 percent have a laptop, and more than half have a smartphone.
Technology's Future in the Classroom:
Instant connectivity has evolved from a means of personal contact to a platform for educational instruction and outreach. In certain cases, social media is now being acknowledged as a valid method of education, and organizations like Scholastic Teachers offer good assistance and advice to teachers. Many professors utilize social media to connect directly with their students or to create forum-style groups for students to speak with one another, and the technique appears to be effective in delivering one-on-one attention to students' queries and concerns.
• Bio metrics, a type of technology that recognizes people based on their physical or behavioral characteristics, is on the horizon. Based on bio metric signals, the science will be utilized to detect students' physical and emotional states in the classroom, allowing course content to be tailored to each individual's requirements.
• Augmented Reality (AR) glasses, reported to be on Google's release list, are a second up-and-coming technology that may open up a whole new universe for education.
•Multi-touch surfaces are frequently utilised through devices like the iPhone, but the technology might become more important to education through completely multi-touch surfaces like desks or workstations.
