First computer
By 1938 the United States Navy had developed an electromechanical analog computer small enough to use aboard a submarine. This was the Torpedo Data Computer, which used trigonometry to solve the problem of firing a torpedo at a moving target. During World War II similar devices were developed in other countries as well. -
First E-mail
Sent by computer engineer Ray Tomlinson in 1971, the email was simply a test message to himself.

First 3D printer.
Early additive manufacturing equipment and materials were Developed in the 1980s.[8] In 1981, Hideo Kodama of Nagoya Municipal Industrial Research Institute invented two additive methods for fabricating three-dimensional plastic models with photo-hardening thermoset polymer, where the UV exposure area is controlled by a mask pattern or a scanning fiber transmitter. -
Laptop
A laptop, often called a notebook or "notebook computer", is a small, portable personal computer with a "clamshell" form factor, an alphanumeric keyboard on the lower part of the "clamshell" and a thin LCD or LED computer screen on the upper part, which is opened up to use the computer.

The iPhone was notable for abandoning the use of a stylus, keyboard, or keypad typical for smartphones at the time, in favor of a large touchscreen for direct finger input as its main means of interaction. -
Virtual Reality.
Virtual reality (VR) is a computer technology that uses virtual reality headsets, sometimes in combination with physical spaces or multi-projected environments, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment. A person using virtual reality equipment is able to "look around" the artificial world, and with high quality VR move around in it and interact with virtual features or items
