Name three recent advances that are influencing os design.

The three recent advances are:

1. Cloud Technology

2. Asynchronous Transfer Mode

3. GUI technology

Explanation:

1. Cloud Technology:

Withe the advent of this technology it has become more convenient to store and access the programs and data over the internet.

The increase in the use of this technology has influenced the Operating system to be designed in a more distributed manner.

2. Asynchronous Transfer Mode:

This mode allows the data transfer by using the methodology of flow control for the transfer of start and stop data bits.

The increased use of ATM for the transfer of data bit stream between components to obtain greater through put  has also influenced the design of the Operating System.

3. Graphic User Interface (GUI technology):

With the help of indicators (visual) and graphical icons, this technology allows the interaction with electronic devices.

The progress in this technology and the interfaces it provided the users with has been through many changes thus influencing the operating system  

to improvise their design thus enabling the smooth User Interface experience.

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
