What types of file systems cannot be used under Windows 2000 Professional?
Correct Answer
C. FAT 16
Explanation
Windows 2000 Professional does not support the FAT 16 file system. FAT 16 is an older file system that has limitations in terms of maximum file size and partition size. Windows 2000 Professional supports the NTFS 4.0 file system, which is more advanced and offers features such as improved security, file compression, and support for larger file sizes and partition sizes. Therefore, FAT 16 cannot be used under Windows 2000 Professional.

POST stands for...
Correct Answer
A. Power-On-Self-Test
Explanation
POST stands for Power-On-Self-Test. This is a diagnostic test that is performed by a computer or other electronic device when it is first powered on. The purpose of the test is to check the hardware and software components of the device to ensure they are functioning correctly. The POST test typically checks the processor, memory, and other essential components to ensure they are working properly before the device boots up. This test is important because it helps to identify any potential issues or errors that may prevent the device from functioning correctly.
9.
When a computer is switched on, where is the operating system loaded?
Correct Answer
A. BIOS
Explanation
When a computer is switched on, the operating system is loaded into the BIOS (Basic Input/Output System). The BIOS is a firmware that is stored on a chip on the computer's motherboard. It is responsible for initializing and testing hardware components, as well as providing basic communication between the hardware and the operating system. During the boot process, the BIOS locates the operating system on the computer's storage device and loads it into the computer's memory (RAM) to be executed. Therefore, the operating system is loaded into the BIOS when the computer is switched on.
10.
BIOS is a ……….?
Correct Answer
A. Program
Explanation
BIOS stands for Basic Input/Output System. It is a program that is stored on a computer's motherboard. BIOS is responsible for initializing hardware components, performing diagnostic tests, and loading the operating system. It provides a bridge between the hardware and the operating system, allowing them to communicate effectively. Therefore, the correct answer is Program.
11.
. …………command is used for converting FAT 32 to NTFS file system in windows.
Correct Answer
convert drive letter: /fs:ntfs
convert drive name: /fs:ntfs
convert c: /fs:ntfs
Explanation
The "convert" command is used in Windows to convert a file system from FAT 32 to NTFS. This can be done by specifying the drive letter or drive name followed by the "/fs:ntfs" option. For example, "convert drive letter: /fs:ntfs" or "convert drive name: /fs:ntfs". Another way to convert is by specifying the drive letter directly, such as "convert c: /fs:ntfs".

………command is used for partition the hard disk in windows 98?
Correct Answer
fdisk
Fdisk
Explanation
The correct answer is "fdisk" or "Fdisk". Fdisk is a command used in Windows 98 to partition the hard disk. It allows users to create, delete, and modify partitions on the hard drive, which is necessary for organizing and managing data on the computer. By using the fdisk command, users can allocate space for different operating systems, create multiple partitions, and set the active partition for booting the system.
15.
How many maximum primary partitions can we do it in windows operating system?
Correct Answer
C. 4
Explanation
In the Windows operating system, a maximum of four primary partitions can be created. This limitation is due to the partition table format used by Windows, known as the Master Boot Record (MBR) partitioning scheme. The MBR partition table can only accommodate up to four primary partitions. If more partitions are needed, an extended partition can be created, which can then be divided into logical partitions. However, in terms of primary partitions alone, the maximum is four.
16.
CMOS stands for………?
Correct Answer
complementary metal oxide semiconductor
Complementary Metal Oxide Semiconductor
Explanation
CMOS stands for complementary metal oxide semiconductor. It is a technology used in the fabrication of integrated circuits. The term "complementary" refers to the fact that the technology uses both p-type and n-type metal oxide semiconductor field-effect transistors (MOSFETs) to achieve low power consumption and high noise immunity. The metal oxide semiconductor refers to the materials used in the construction of the transistors. CMOS technology is widely used in the design of digital logic circuits, microprocessors, and other electronic devices due to its low power consumption and high integration density.
17.
What are the types of hard disks……….?
Correct Answer
PATA, SATA, SCSI, SAS
IDE, SATA, SCSI, SAS.
pata, sata, scsi, sas.
Explanation
The correct answer is PATA, SATA, SCSI, SAS. PATA stands for Parallel Advanced Technology Attachment, which is an older type of hard disk interface. SATA stands for Serial Advanced Technology Attachment, which is a newer and faster type of interface. SCSI stands for Small Computer System Interface, which is a high-performance interface used in servers and high-end workstations. SAS stands for Serial Attached SCSI, which is a newer and faster version of SCSI. IDE is not a correct type of hard disk interface and is therefore not included in the correct answer.

RAM is a ………..memory device?
Correct Answer
A. Volatile
Explanation
RAM is a volatile memory device. Volatile memory refers to a type of computer memory that requires a constant power supply to retain stored data. In the case of RAM, it stores data that is actively being used by the computer's operating system and applications. However, once the power is turned off or the computer is restarted, the data stored in RAM is lost. This is in contrast to non-volatile memory devices, such as hard drives or solid-state drives, which can retain data even when power is not supplied.
