Which of the following types of SATA hard disk drives is used for the Desktop computers?
A. 3.5 inches
B. 6.2 inches
C. 1.8 inches
D. 2.5 inches
Answer: A
Explanation:
The 3.5 inches SATA hard disk is used for the Desktop computers. The Serial ATA (SATA) computer bus is a storage-interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives. SATA offers several compelling advantages over the older parallel ATA (PATA) interface, such as reduced cable-bulk and cost, faster and more efficient data transfer, full duplex, and hot swapping. It is designed to replace the older ATA (AT Attachment) standard (Parallel ATA). All SATA devices support hot plugging and hot swapping. SATA supports Native Command Queuing (NCQ) for enhanced performance. Answer options C and D are incorrect. The 1.8 inches and 2.5 inches hard disk drives are used in laptops. Answer option B is incorrect. There is no such size of SATA hard disk drive as 6.2 inches.

You are selecting memory to put in to a laptop. Which of the following types of RAM chips would you most likely select?
A. 144 PIN
B. 72 PIN
C. 240 PIN
D. 184 PIN
Answer: A
Explanation:
Both MicroDIMM and SO-DIMM come in a 144 pin configuration, and are used for laptops. What is SO-DIMM? Small Outline Dual Inline Memory Module (SO-DIMM) is a type of memory module that comes in 72 pins and 144 pins. The 72-pin SO-DIMM supports 32-bit transfers, and the 144-pin SO-DIMM supports 64-bit transfers. It was introduced for laptops. SO DIMMs come in smaller packages, consume lesser power, but are more expensive than DIMMs. Answer option B is incorrect. The 72-pin is a legacy chip used in PC's. Answer option D is incorrect. The 184-pin is used in DDR RAM in PC's. Answer option C is incorrect. The 240-pin is used in DDR2 and DDR3 RAM in PC's. What is DDR3 SDRAM? DDR3 SDRAM or double-data-rate three synchronous dynamic random access memory is a random access memory interface technology used for high bandwidth storage of the working data of a computer or other digital electronic devices. DDR3 is part of the SDRAM family of technologies and is one of the many DRAM implementations. DDR3 SDRAM is an improvement over its predecessor, DDR2 SDRAM, and the two are not compatible. The primary benefit of DDR3 is the ability to transfer at twice the data rate of DDR2, thus enabling higher bus rates and higher peak rates than earlier memory technologies. DDR3 memory power consumption is 30% less as compared to DDR2 modules.

NTFS supports file encryption and you can only encrypt files on an NTFS partition. What is NTFS? Hide NTFS is an advanced file system designed for use specifically in Windows NT, Windows
2000/2003, and Windows XP operating systems. It supports file system recovery, large storage media, long file names, and other features.
NTFS offers features such as disk quotas, distributed link tracking, compression, and mounted drives. NTFS also offers security features, such as encryption and file and folder permissions. These features are not available on FAT volumes.
Answer option A is incorrect. The that your operating system is on an NTFS partition does not change the that only NTFS partitions support encryption.
Answer option B is incorrect. FAT does not support encryption.
