The assertion is untrue. Selective acknowledgment is used by SR. The alternating-bit protocol is the same as the SR protocol with sender and receiver window sizes of 1.

The GBN protocol and the alternating-bit protocol are both compatible with transmitter and receiver window sizes of 1. True Similar to GBN, the sender and receiver windows for the alternating bit protocol are both 1. The acknowledgement number is the sequence number of the next byte that the receiver expects to receive. The receiver uses the receiver ack'ing sequence number x to acknowledge all data bytes received up until (but excluding) byte number x. The sequence number is always accurate. We saw that the sender needs sequence numbers to let the receiver know whether a data packet is valid.

Overflow: If the sum of two integers is excessively long, it will require a lot of room to fill, and the available space will not be sufficient. The fact that it will exceed the range will result in the overflow condition.

When there is an overflow, the result was either too big or too tiny for the original data type. If both operands are positive and the result is negative when two signed 2's complement numbers are added, or if both operands are negative and the result is positive, overflow is detected. If the overflow flag is on while performing two's complement (signed) arithmetic, the answer is incorrect because either you added two positive integers and obtained a negative result, or you added two negative numbers and obtained a positive result.

Arranging the array's elements in ascending order makes it easy to identify the element with the largest value. Following sorting, the first element will represent the array's smallest element, followed by the second-smallest element, the largest element, and so on.

Find the maximum by iterating through the array first. Together with its index, save this as the first maximum. Now search through the entire array for the second maximum, leaving off the largest element. Find the third largest element by iterating through the array three times and omitting the maximum and second maximum. The goal of the method getresult(int arr[],int n) is to identify the array's maximum and minimum elements with the fewest possible comparisons.

The types of VHDL data include bit, bit vector, std logic, std logic vector, and user defined. Standard logic is read as "std logic," while standard logic vector is read as "std logic vector." Bit and bit vector are read in their original form. When the coder specifies the signal type, it becomes the user-defined type.

Assume that x is a char variable that has been declared and already given a value (x>='A' && x<='Z') whose value is true if x is a uppercase letter.

In certain programming languages, including C, C++, C#, and Java, the acronym char is used as a reserved keyword. Character is the abbreviation for this data type, which can store data in the form of a single character (letter, number, etc.). A char variable, for instance, might have the value of any single character, such value as "A," "4", or "#."

Additionally, many techniques used with string values may be referred to by the acronym in other languages that do not support the char data type. JavaScript, for instance, includes functions like charAt() and charCodeAt() that return values associated with the caller string.
