Computer Memory and Storage

A 64-bit operating system is primarily characterized by having CPU registers that are 64 bits wide, allowing it to process 64-bit chunks of data natively and address a much larger memory space.

A 64-bit OS manages memory addresses and processes data in 64-bit chunks. The primary distinction is how it handles data in main memory (RAM), using 64-bit addresses rather than 32-bit. CPU registers are typically 64-bit too, but that's a hardware consequence. Hard disk storage format is unrelated to OS bit-architecture.

SATA stands for Serial Advanced Technology Attachment. It is a computer bus interface that connects host bus adapters to mass storage devices like hard drives and SSDs. The 'Serial' refers to the data transfer method using serial communication, which replaced the older Parallel ATA (PATA) standard.

RAM stands for Random Access Memory, which allows data to be accessed in any random order rather than sequentially. 'Reliable' and 'Recent' are incorrect - the key characteristic is the ability to access any memory location directly. Option D has a typo ('Randam').

USB stands for Universal Serial Bus, an industry standard for cables, connectors and communication protocols between computers and devices. It uses serial communication, not simple or unique connections. Option D incorrectly uses lowercase 'bus'.

HDD stands for Hard Disk Drive, a data storage device using magnetic storage. 'Device' in options B and D is incorrect - the middle term must be 'Disk'. Option C is incomplete.

DRAM stands for Dynamic RAM, which requires periodic refreshing to maintain data. This is different from static RAM (SRAM). The key characteristic is that it's 'Dynamic', not Dual, Device, or Durable.

The minimum RAM requirement for Windows Server 2003 Enterprise Edition installation was 128 MB. However, this was the bare minimum - Microsoft recommended 256 MB or more for acceptable performance in production environments. The 128 MB requirement was for installation only, not practical operation.

RAM stands for Random Access Memory, which allows data to be read and written in any order. The other options are incorrect expansions of the acronym RAM.

RAM stands for Random Access Memory, a type of computer memory that allows data items to be read or written in almost the same amount of time regardless of the physical location of data inside the memory. The other options are incorrect expansions.

Unused SaveVol space can be reclaimed to free up storage resources. When sessions become problematic or stale, aborting them and performing a resynchronization operation is a valid recovery approach to maintain data consistency.

RAID 6 uses dual parity and can withstand the failure of up to two drives simultaneously, unlike RAID 5 which only handles single drive failures.

Windows XP supports both FAT32 and NTFS file systems. The option 'Both of them' correctly indicates that XP is compatible with multiple file system types.

Blu-ray discs have significantly higher storage capacity (25GB single-layer, 50GB dual-layer) compared to DVDs (4.7-8.5GB), CDs (700MB), and floppy diskettes (1.44MB). The dual-layer Blu-ray can store up to 50GB of data, making it the highest-capacity optical media format among the options listed.
