Technical Support Fundamentals. Week 2: Assemble a Computer
Which mechanisms do we use to transport binary data and memory addresses? Check all that apply.
Address Bus; The EDB is used to transport binary data and the Address Bus is used to transport memory addresses. The External Data Bus; The EDB is used to transport binary data and the Address Bus is used to transport memory addresses.
How long will it take to transfer a file size of 1GB on a USB 2.0 and a USB 3.0 drive? usb 2.0 -> transfer speeds of 480Mb/s usb 3.0 -> transfer speeds of 5 Gb/s usb 3.1 -> transfer speeds of 10 Gb/s
~17 seconds on a usb 2.0 drive; ~2 seconds on a usb 3.0 drive;; Theoretically, USB 2.0 has a bandwidth of 480 Mb/s, which is roughly 60 MB/s. It would take around 17 seconds to transfer 1024 MB of data.
Which of these functions does the BIOS perform? Check all that apply.
POST; The BIOS performs a POST to check what devices are connected to the computer. It also initializes hardware on boot. Checks what devices are connected to the computer; The BIOS performs a POST to check what devices are connected to the computer. It also initializes hardware on boot. intializes hardware; The BIOS performs a POST to check what devices are connected to the computer. It also initializes hardware on boot.
Where does the CPU store its computations?
Registers; When the CPU does computation, it stores information in registers first.
True or false: If you plug in a 220v appliance into a 120v outlet, the appliance could get damaged.
True; While plugging a 220v appliance into a 120v outlet won't cause immediate harm to your appliance, it could still cause appliance deterioration.
What is the difference between a traditional BIOS and UEFI? Check all that apply.
UEFI is meant to become the new standard for BIOS; UEFI is the new standard for BIOS. It has become the default BIOS on new systems and it has better compatibility with newer hardware. UEFI has better compatibility with newer hardware; UEFI is the new standard for BIOS. It has become the default BIOS on new systems and it has better compatibility with newer hardware. UEFI has become the default BIOS on new systems; UEFI is the new standard for BIOS. It has become the default BIOS on new systems and it has better compatibility with newer hardware.
What is the difference between a ROM chip and a RAM chip? Check all that apply.
a ROM chip stores permanent data. A RAM chip stores temporary data.; A ROM chip stores permanent data and will keep its data if there is a power failure. A RAM chip stores temporary data and will wipe its data in a power failure. a ROM chip is non-volatile and will keep its data in the case of a power failure. A RAM chip is volatile and will wipe its data in the case of power failure; A ROM chip stores permanent data and will keep its data if there is a power failure. A RAM chip stores temporary data and will wipe its data in a power failure.
What characteristics distinguish a Solid State Drive from a Hard Disk Drive?
smaller form factor; SSDs have non-moving parts, are a smaller form factor, and also utilize non-volatile memory. non-moving parts; SSDs have non-moving parts, are a smaller form factor, and also utilize non-volatile memory.
