A digital communication system sends and receives 7-bit data packages. In which of the following cases a parity bit 1 will be needed if an even parity transmission system is used?

A digital communication system sends and receives 7-bit data packages. In which of the following cases a parity bit 1 will be needed if an even parity transmission system is used? Correct Answer 0110010

Only the data package 0110010 contains odd number of 1s. So, an even parity system will add a parity bit of 1 to avoid error when transmitting the package. Hence the right answer is 0110010.

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. We live in digital times. The digital is not just something we use strategically and specifically to do a few tasks. Our very perception of who we are, how we connect to the world around us, and the ways in which we define our domains of life, labour and language are hugely structured by the digital technologies. The digital is everywhere and, like air, invisible. We live within digital systems, we live with intimate gadgets, we interact through digital media, and the very presence and imagination of the digital has dramatically restructured our lives. The digital, far from being a tool, is a condition and context that defines the shapes and boundaries of our understanding of the self, the society, and the structure of governance. Which among the following is the most logical and essential message conveyed by the above passage?
