Question
1- It takes 12.5ms to transmit 10 characters in a RS232 link. Assume that each data is made of 8 bits, with even parity, and 2 stop bits. What is the approximate baud rate of the link
2- Give an example of an ethical issue that involves computer software.
3- Give at least two examples of intellectual property.
4-Give one example each for cybercrimes and cyber-related crimes, respectively.
5- Name one example of professional code of ethics for computing professionals.
6-Give an example of a software product that has global impact.
7-Give an example where you benefits from computing technologies in getting better services in your daily life
8- Name at least one example of new computing technology that you envision will come into reality in next five years.
Explanation / Answer
1.baud rate is defined as the total number of bits passing through the rs232 serial port per second
now, given that there are 10 characters each of 11 bits (8 bit data + 2 start and stop bits + 1 parity bit ) . so , total number of bits = 11*10 = 110
the time given for transferring this 110 bits = 12.5 ms
hence number of bits passsing each second = 110*1000/ 12.5
= 8800 baud (ans)
2..There are ethical concerns directly related to the practice of software engineering which are not merely fanciful questions or intellectual exercises. The practicing software engineer engages in a social process during software production and thereby acquires obligations to: users, clients, customers, colleagues, supervisors, the organization for which he works, and the discipline of software engineering. The ethical problems faced by the software engineer involve: the end product, the process of developing that product, and the human interactions in the development of the product.
3. Intellectual property (IP) refers to creations of the mind.
example : inventions; literary and artistic works; designs; and symbols
