<h3>What do you mean by
Visual perspective?</h3>
Visual perception or sight can be defined as the ability to interpret the encircling surroundings via photopic vision, color vision, scotopic vision, and mesopic vision, the usage of light withinside the visible spectrum meditated through items withinside the surroundings.
It also means the ability to see the world through others' perspectives, which takes into account what and how they see it.
Thus, The factor that influenced Ravi's perspective towards the people can be referred to as <u>Visual perspective.</u>

In a polling-based network receives, the operating system keeps checking the status register after a fixed time interval to see whether a device needs hardware attention or not. CPU gradually checks the status of receive bit after a defined time interval of a clock and if the value of receive bit is true then data is moved from the RX register to the memory. In interrupt-based networks, whenever a device needs hardware processing then an interrupt is raised to inform the CPU for device attention. The data of the device is transferred to memory from the network card.
Polling is a protocol, not a hardware mechanism where the device gets attention by CPU. An interrupt is a hardware mechanism, not a protocol where the device gets attention by the interrupt handler. In polling, during receiving, parts of received data need to transfer to memory but in case of interrupts, whole data is transferred at once after receiving is done. An interrupt is a heavy operation as compared to pooling because hardware involves in it. For large amounts of data, Polling becomes an inefficient method. In polling, CPU gradually checks devices at regular intervals whereas the Interrupt handler can send interrupt at any time. Each device has its own Command ready bit which indicates whether the device requires servicing or not. In polling, CPU wastes numerous clock cycles by repetitively checking the command-ready little bit of each device. In Interrupt based network, the interrupt request line indicates whether the device requires servicing or not. In interrupt-based network, CPU cycles not wasted but CPU is disturbed only when device send interrupt signals.
Relative performance between programmed I/O and DMA:
For determining the relative performance between programmed I/O and DMA, important factors are:
1. Size of data
2. Frequency of operations
Answer:
a) only one digit changes as the number increases.
Explanation:
Let us first understand what does it mean when we say only one digit changes as the number increases using the Reflected Binary code (also called Gray code)
consider the 4 bit representation of Binary coded decimal and RB codes
Decimal | Binary code | Reflected binary (RB) code
0 0000 0000
1 0001 0001
2 0010 0011
3 0011 0010
4 0100 0110
5 0101 0111
As you can see in the case of binary codes, there are more than one digit changes between two consecutive numbers.
But notice that in the case of Gray codes, there is always one digit change between two consecutive numbers.
The problem with the binary codes is that the more digits change there states the greater is the chance of ending up with random transitional values rather than real values which can be incorrect. The RB code solves this problem by only changing one digit at a time.
The RB code is widely used in linear and rotary encoders, error correction and digital logic design.
Answer:
b. Redundant hardware and data backup systems
Explanation:
Data privacy is important where a company collects, processes and stores personal information.In the US-EU have laid down regulations to ensure data privacy is maintained. It is a requirement before collection of personal data, to clearly state why the data is being collected and how it will be used.The individuals whose data is being processed have a right to access their data at no cost during processing . Of great importance is the security of the data so as to maintain its integrity, Companies are required to take steps in protecting the data from unauthorized access, processing and accidental loss.redundant hardware and data backup system are used by companies as a fail-safe mechanism in data protection but they are not a requirement in data privacy, although they enhance it.
