Answer:
Mode Name: RS-485, half duplex, 2 wire based for serial data transmission
Reason 1: less noisy
Reason 2: around 32 receivers allowed, and that is enough for the requirement mentioned in this question.
Explanation:
Serial data transmission is of two types, which are synchronous data transmission and asynchronous data transmission. However, here continuous transmission is required, and hence no stop is required. Hence, it's the Synchronous data transmission. Also, you need to only transmit at a time from one transmitter, and no receiver or the screen is going to respond in that time, considering AI surveillance is not in progress meanwhile. However, we have 4 wire, full-duplex RS-485 also available, though here we need only 2 wire half-duplex RS-485. And this will certainly cater to our requirements. And we can but should not use RS-422A as the number of receivers, in that case, is limited to merely 10.
Answer:
False
Explanation:
Higher efficiency should mean that it uses more power, causing it to heat up.
Applications software (also called end-user programs) include such things as database programs, word processors, Web browsers and spreadsheets. A word processor could be classed as general purpose software as it would allow a user to write a novel, create a restaurant menu or even make a poster.
Answer:
E. Traditional leaders in communication have lost some control over information
Explanation:
Due to the quick development of new technologies like Internet, cable etc, traditional leaders in communication have lost some of their control over information. This means that the technological advancement is disruptive for traditional leaders. Following examples are given to elaborate the consequences of advancement in new technology in digital era.
With the establishment of new channels like CNN, Fox News and internet bloggers, the old television network news shows like ABC, NBC lost their audiences.
Email technology has taken on some of the postal service's responsibilities and outperforms attempts to control communication outside national borders. This replaced the postal mail which used to take months to reach the destination.
The Internet and social media websites are transforming the way in which we access and interact with media culture. Before internet most people would watch popular TV shows in at the time they originally aired it. This scheduling gave common media interactions at specific times within our society. We still watch these TV shows but now we watch them at our own ease through websites. Using You tube we can upload our own media instead of viewing mainstream television.
The binary representation of +3997 is 1111 1001 1101.
In one's complement this is simply adding a sign bit and inverting all the bits:
1 0000 0110 0010
The two's complement is the one's complement plus 1:
1 0000 0110 0011
That's 13 bits. Normally the sign bit would be at an 8, 16 or 32,... bit boundary.
For -436 it's 10 0100 1100 and 10 bits
