answer true or false to the following questions and briefly justify youranswer: a. with the sr protocol, it is possible for the sender to receive an ack for a packet that falls outside of its current window.

Answers

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.

Answers

The new network card was discovered in device management, but since Windows doesn't recognize it, we need to boot into Safe Mode and remove the network driver. Is the better tool to make Windows properly load

Only the bare minimum background services necessary for Windows to boot and run are initialized when a machine boots in Safe Mode. You can then identify and remove the problematic driver from this mode. The BIOS/UEFI settings interface on some systems will allow you boot into Safe Mode, but you are unable to delete the driver that caused your computer to crash from there. Start-up Repair will check your computer for issues like damaged or missing system files, but it won't let you remove the problematic device driver, which will result in a crash.

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.

Answers

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. For instance, the charAt() method returns a string containing one character, which is the character that is present at the place specified in the function's parameter.

Windows 10 is defined as a Microsoft operating system for laptops, tablets, embedded technology, and internet-connected gadgets. The user interface of Windows 10 is intended to change depending on the type of device being used and the various input methods. It provides two different user interface settings: a mouse and keyboard-optimized interface and a touchscreen-specific "Tablet mode."

From the Windows 11 or Windows 10 login screen, start Windows in Safe Mode. Launch the computer again. Click Power > Restart while holding down the Shift key at the sign-in screen. Select Troubleshoot > Advanced Options > Startup Settings > Restart from the Choose an Option screen that appears after the machine restarts.

Thus, as Windows 10 is loading, assuming it is enabled, advanced boot options screen appears. Hence option D is correct.
