Question

which statement accurately differentiates hdd (hard disk drive) storage from ssd (solid state drive) storage?

• 1 po

hdds offer lower latency and consume less power than the flash - memory - based ssds.
ssds rely on magnetic platters for data storage while hdds utilize semiconductor chips.
hdds are typically cheaper per gigabyte and possess moving parts, unlike the faster ssds.
ssds have a shorter operational lifespan due to memory cell degradation compared to hdds.

a technician needs to connect a computer to a high - speed local area network (lan) for stable internet and file sharing. which port is essential?

• 1 point

hdmi port, used for transmitting high - definition video and synchronized audio signals.
universal serial bus (usb - a) port, typically used for connecting keyboards and mice.
ethernet (rj - 45) port, designed for stable, wired network connectivity and data transfer.
standard audio jack, which is utilized for connecting analog headphones and external microphones.

the speed of a computers central processing unit (cpu) is primarily determined by which two intertwined metrics?

• 1 point

its capacity for permanent data archiving and the total voltage required for system boot.
the clock speed (ghz) and the number of independent processing cores it contains.
the available amount of volatile memory and the total number of peripheral ports supported.
its physical dimensions (form factor) and the density of its integrated circuit pathways.

Explanation:

First Question

• HDDs use magnetic platters and have moving parts. They are cheaper per gigabyte. SSDs use semiconductor chips (flash - memory), are faster, have no moving parts.
• Option 1: SSDs have lower latency and consume less power than HDDs. So this option is wrong.
• Option 2: HDDs rely on magnetic platters and SSDs use semiconductor chips. So this option is wrong.
• Option 4: HDDs have a shorter operational lifespan compared to SSDs (due to mechanical wear of moving parts). So this option is wrong.

• HDMI port is for video and audio. USB - A is for peripheral devices like keyboards and mice. Standard Audio Jack is for audio input/output.
• Ethernet (RJ - 45) port is specifically designed for wired network connectivity which is needed for stable internet and file sharing in a LAN.

• Clock speed (GHz) determines how many cycles the CPU can perform per second. The number of cores allows the CPU to handle multiple tasks simultaneously.
• Capacity for permanent data archiving is related to storage (not CPU speed). Voltage for system boot is a power - related metric. Volatile memory (RAM) affects performance but is not a metric that primarily determines CPU speed. Peripheral ports are for connecting external devices. Physical dimensions and circuit pathways do not primarily determine CPU speed.

Answer:

C. HDDs are typically cheaper per gigabyte and possess moving parts, unlike the faster SSDs.
