Computer Memory and Storage

Windows stores device driver configuration in the Registry database, specifically under HKLM\SYSTEM\CurrentControlSet\services. The Registry is a hierarchical database that stores all Windows configuration settings. BIOS and CMOS are firmware-level storage for motherboard settings, not Windows-specific driver configurations. EEPROM is a type of memory chip, not a configuration storage system.

Molex connectors are the standard 4-pin power connectors used to supply electricity to internal optical drives like CD-ROM and DVD drives, as well as hard drives. They provide +5V and +12V power rails. DB-15 connects older game ports or monitors, PS/2 is for keyboards and mice, and RJ11 is for telephone lines - none of these power disc drives.

CDRAM (Cache DRAM) is not a standard type of computer RAM. The common RAM types include DDR I, DDR II, DDR3, DDR4, and SDRAM (Synchronous DRAM). CDRAM is the correct answer as it's not a standard RAM category.

Page faults occur when the system needs to access data that has been moved from RAM to virtual memory on disk. While the question states 'due to RAM,' it's more accurate to say page faults occur due to insufficient RAM or the virtual memory paging system. However, given the options, RAM is the best answer as PROM, ROM, and CD R/W are not involved in virtual memory management.

In the standard data storage hierarchy, TB (Terabyte) is the largest unit listed, followed by GB (Gigabyte), MB (Megabyte), and KB (Kilobyte). The progression is: 1 KB = 1024 bytes, 1 MB = 1024 KB, 1 GB = 1024 MB, and 1 TB = 1024 GB. Larger units like PB (Petabyte) and EB (Exabyte) exist but aren't listed.

Storage units increase by powers of 1024: KB is smallest, then MB, then GB, then TB. TB (Terabyte) is the largest among these options, equal to approximately 1 trillion bytes.

TB (Terabyte) is the largest unit among the options. The storage capacity hierarchy is: KB (Kilobyte) < MB (Megabyte) < GB (Gigabyte) < TB (Terabyte). One TB equals 1024 GB, one GB equals 1024 MB, and one MB equals 1024 KB.

FAT (File Allocation Table) viruses specifically target and damage the FAT sections of the hard disk, which the operating system uses to locate and access files. Boot Sector Viruses (B) infect the boot sector, while Hard Disk Virus (D) is not a standard classification. Crypto Viruses (A) encrypt files rather than damaging access sections.

Obliviate is the Memory Charm used to erase or completely clear a person's memories, commonly used by wizards to maintain the Statue of Secrecy. Gilderoy Lockhart was famous for (mis)using this spell. The other options are made-up spell names.

Microsoft Windows XP had minimum system requirements of 64MB RAM, though 128MB was recommended for acceptable performance. The question asks for minimum requirements, not recommended, making 64MB the correct answer. Windows XP could technically run on 64MB, but performance would be very slow. Many users upgraded to 256MB or more for better performance.

Disk Management is the Windows utility that allows users to view and modify disk partition information. It shows all drives, their partitions, sizes, and status. Chkdsk checks for filesystem errors. Device Manager manages hardware devices. Scandisk is an older disk checking utility. Only Disk Management provides the full partition viewing interface.

Blu-ray discs have the highest storage capacity among these options. A standard Blu-ray can store 25GB (single-layer) or 50GB (dual-layer). DVDs store 4.7GB (single-layer) or 8.5GB (dual-layer). CDs store about 700MB. Floppy diskettes store only 1.44MB. Blu-ray's capacity significantly exceeds the other formats.

Common DVD drive types include DVD-RW (rewritable), DVD+RW (another rewritable format), and DVD-RAM (a random-access rewritable format). DVD-RD is not a standard DVD drive type - it appears to be a fabricated or incorrect term. Real DVD types include ROM, R, RW, RAM, and combinations like DVD+RW/-RW.

ROM (Read-Only Memory) is a type of computer memory that can only be read from and not written to after manufacture. Unlike RAM (which can be both read and written), ROM contains permanent or semi-permanent data that is essential for booting and basic system operations.
