What is the main advantage of using a CPU in 64-bit mode? - correct answer ✔64-bit software is more
reliable and a bit faster than 32-bit software. It also supports more system memory.
What is a typical speed for a mid-range CPU to run at? - correct answer ✔Around 2 GHz; budget
models might run as low as 1 GHz, while faster ones run at 3 or 4 GHz.
You want to purchase a computer with a fast graphics interface. What type of expansion slot should you
look for? - correct answer ✔PCIe x16—this is a type of PCI Express slot that uses 16 'lanes'. Each lane
can transfer 250 MBps (or 500 MBps for PCIe 2 and 1 GBps for v3).
What type of component provides a passive cooling solution? - correct answer ✔A heatsink
How would you access the system setup program on a PC? - correct answer ✔Historically, by pressing
the appropriate key during startup (ESC, DEL, F1, F2, or F10). Modern PCs often use fast boot modes that
require some other means of booting to the firmware setup program.
