D386 Hardware and Operating Systems Essentials - Set 1 - Part 1

Correct Answer: Connects a host to other devices in a storage network

The HBA serves as a bridge between the host system and storage devices, facilitating data transfer and communication.

Correct Answer: A data storage device that uses flash memory

SSDs store data in memory chips and have no moving parts, which allows for faster access times compared to traditional hard drives.

Correct Answer: A combination of a mechanical hard drive and an SSD

Hybrid drives combine the larger storage capacity of mechanical drives with the speed of SSDs to optimize performance and storage.

Correct Answer: PATA drives (IDE drives)

PATA (Parallel ATA) drives utilize thicker cables for data transfer and have slower performance compared to modern SATA drives.

Correct Answer: To connect secondary storage devices with a more advanced interface than PATA

SATA (Serial ATA) drives provide a faster and more efficient way to connect storage devices compared to older PATA technology.

Correct Answer: Laser technology

Optical drives utilize lasers to read from and write data to discs, making them suitable for archiving and distribution.

Correct Answer: Trimming

Trimming helps maintain the performance of SSDs by organizing data and minimizing fragmentation on the drive.

Correct Answer: Predicts when a drive is likely to fail

SMART (Self-Monitoring, Analysis, and Reporting Technology) monitors various metrics to alert users of potential drive failures.

Correct Answer: Wear leveling

Wear leveling distributes write and erase cycles across the memory blocks of an SSD to prolong its lifespan and improve reliability.

Correct Answer: Solid-State Drives (SSDs)

SSDs provide significantly faster access and transfer speeds due to their use of flash memory and lack of moving parts.

Correct Answer: The process of transferring data between storage types, formats, or computer systems

Data migration involves moving data from one system or format to another, often during upgrades or system changes.

Correct Answer: A high-speed serial computer expansion bus standard

PCIe (Peripheral Component Interconnect Express) is designed to replace older bus standards with a faster and more efficient interface for connecting hardware.

Correct Answer: A client-server model where the client performs the majority of processing

Thick-client computing places most processing responsibilities on the client, often requiring significant local resources.

Correct Answer: Resources such as servers and applications shared among people within an organization

Internal shared resources refer to the collective hardware and software assets that are accessible to users within a specific organization.

Correct Answer: Multiple virtual environments for applications on a personal computer

Client-side virtualization allows a personal computer to host multiple virtual machines, enabling different applications to run independently.

Correct Answer: Utilizing servers and software over an internet connection

Cloud computing enables users to access and utilize resources such as storage and applications via the internet, providing flexibility and scalability.

Correct Answer: Non-volatile Memory Express

NVMe is a protocol designed to utilize high-speed PCIe storage devices, enhancing performance and reducing latency for SSDs.

Correct Answer: A standardized smaller SATA form factor for use in portable devices

mSATA is a compact version of SATA designed for use in laptops and other portable devices, allowing for efficient use of space.

Correct Answer: Flash memory

Flash memory is a non-volatile storage medium that can be electronically erased and reprogrammed, making it suitable for many storage applications.

Correct Answer: Devices that can be added or removed without shutting down the computer

Hot-swappable devices allow users to replace or add components without interrupting the power supply, enhancing flexibility and ease of use.
