Q1. Array Address Calculation (Row Major & Column Major) Problem: An array ARR[-5...15, 10...20] stores elements in Row Major with each element requiring 2 bytes. Base address is 2500. Find address of ARR[10][15]. Answer: Given: • Row range: -5 to 15, so Lr = -5, Ur = 15 • Column range: 10 to 20, so Lc = 10, Uc = 20 • Element size (w) = 2 bytes • Base Address (BA) = 2500 • Find: Address of ARR[10][15] Step 1: Calculate dimensions Number of rows (M) = Ur - Lr + 1 = 15 - (-5) + 1 = 21...

1. Boot Sector Virus
▪ It is a type of virus which infects master boot record (portion of hard disk which helps to load OS) or hard
disks.
▪ The infected code runs when the system is booted from an infected disk.
▪ They infect at a BIOS level. (BIOS checks hardware, and loads the OS).
▪ They use DOS commands (DOS commands are text-based commands used to perform tasks such as file
management, disk management, and running programs) to spread to other floppy disks. Since the floppy
disks are not used,
