Answer: d. Statement 1 is an assertion, Statement 2 is the solution.

Explanation:

The Longest Match rule is a rule which states that whichever lexeme is scanned should always be determined on the support of the longest match available among all the tokens which is accessible. The lexical analyzer used should also follow the rules arrangement, where a reserved word, e.g., a keyword, in a language is given priority over the user input.

IRQ 0 interrupt have _______________ priority<br> ? low<br> ? medium<br> ? highest<br> ? lowest
tekilochka [14]

Answer:

Highest

Explanation:

A interrupt request / IRQ is in which instructions are sent to Cpu and uses an interrupt handler to run distinct program . Hardware interrupts are used to manage occurrences such as obtaining modem or network card information, important presses, or mouse motions.

  • Interrupt request 0. – it is a system timer (can not be altered)
  • Interrupt request 1 – keyboard controller (can not be changed)
  • Interrupt request 2 – cascaded IRQ 8–15 signals (any device configured to use IRQ 2 will genuinely use IRQ 9)
  • Interrupt request 3 – serial port 2 controller
  • Interrupt request 4 –  serial port 1 controller
  • Interrupt request 5 –parallel port 2 and 3
  •  Interrupt request 6 - floppy disk controller
  •  Interrupt request 7 –parallel port 1. If a printer is not present, it is used for printers or for any parallel port. It can also possibly be shared with a secondary sound card with cautious port management.

As interrupt number increases priority level decreases, Priority level 0 is the highest priority level .

Kobotan [32]

Answer:

Refresh the page, it will reset all the underlying code.

Explanation:

Inspecting an element is essential for web developers in building websites faster and better. The Chrome DevTools is a powerful tool that is integrated into the Chrome browser to assist developers in on-the-go website troubleshooting.

Editing codes in the Chrome DevTools console does not affect the source code of the website hosted on a server, it just provides instant editing functions for troubleshooting or website enhancement.

Therefore, refreshing the page, re-loads the website again from its database which will show the unedited website. In our scenario, after refreshing the page, all the deleted DIV that contains all the authentication will reappear again.
