A temporary storage space used by the operating system and applications to pass information to the CPU for processing.

Question 5

Read-Only Memory (ROM)

Answer 5

A memory that saves and stores system data without a constant power source.

Question 6

TPM (Trusted Platform Module)

Answer 6

An international standard designed to secure hardware by integrating encryption keys into devices.

Question 7

BIOS/UEFI

Answer 7

UEFI (Unified Extensible Firmware Interface) and its predecessor BIOS (Basic Input/Output System) are the primary firmware standards used on PCs.

Question 8

Boot Sequence

Answer 8

Boot sequence is one of the more important settings in your BIOS/UEFI. It controls the order in which the computer searches its disk drives for an operating system.

Question 9

Power Management

Answer 9

The BIOS/UEFI power management settings control what happens when the computer doesn’t shut down properly or it goes into, or awakens from, a misconfigured Standby or Hibernate mode.

Question 10

Advanced Configuration and Power Interface (ACPI)

Answer 10

Provides an open standard that operating systems can use to discover and configure computer hardware components, to perform power management by putting unused components to sleep, and to perform status monitoring.

Question 11

DIMM

Answer 11

A 64-bit module which can have memory chips on one or both sides of the package

Question 12

SODIMM

Answer 12

A form factor used in laptops and SFF PCs and is built using integrated circuits

Question 13

SIMM

Answer 13

A 32-bit module that has memory chips on one side of the package.

Question 14

RIMM

Answer 14

A 64-bit module mostly found in older computers which use Rambus technology

Question 15

What firmware security features can be included with the BIOS/UEFI?

Answer 15

• BIOS/UEFI passwords
• Hard drive encryption

• Intrusion detection
• Diagnostic tools

Question 17

Name a data protection and theft recovery solution that protects your devices data and can locate your lost or stolen device?

Answer 17

Lojack

Question 18

What test scans critical components to look for errors that interrupt the boot process?

Answer 18

Start up test

Question 19

What allows the operating system to control the amount of power given to each device and to power them down when not in use?

Answer 19

ACPI

Question 20

State two facts that are true about RAM?

Answer 20

• It is generally faster than hard drives and flash storage.

- It is considered volatile because the data it holds is lost when power is removed from the computer or device.

Question 21

What type of memory module is used in laptops and other small devices?

Answer 21

SODIMM

Question 22

What RAM feature uses an algorithm to detect single-bit and multi-bit memory errors?

Answer 22

ECC

Question 23

What DDR version has a curved contact edge designed to help prevent damage to the module during installation?

Answer 23

DDR4

Question 24

Which of the following uses n algorithm to encode information into a block of bits?

Answer 24

ECC

Question 25

What is an international standard designed to secure hardware by integrating encryption keys into devices?

Answer 25

Trusted Platform Module

Question 26

What is a UEFI feature that verifies an operating system's boot loader is electronically signed by the vendor before it loads?

Answer 26

Secure Boot

Question 27

What performs management functions such as specifying the memory's clock signal?

Answer 27

Control Bus

Question 28

What is a software programmed into a read-only memory?

Answer 28

Firmware

Question 29

What is flashing?

Answer 29

A process of rewriting the information stored on the chip

Question 30

Three types of Random Access Memory (RAM)

Answer 30

- SIMM - DIMM - SODIMM - RIMM

Question 31

RAM features

Answer 31

- Buffering – have additional circuits that hold data and manage electrical signals before information is passed between RAM and the memory controller. - Parity – Regular memory contains one bit of memory for every bit of data it stores – 8 bits for each byte of data. Parity memory modules have an extra parity checking bit that can be used to verify each byte of data was correctly read or written by the memory modules. - ECC - A more advanced version of parity that uses an algorithm to encode information into a block of bits. - Clock Speed – Like a processor, every RAM module is rated to operate at a specific clock speed. - Channels - DIMMS and SODIMMS are 64-bit devices, which can transfer 64 bits of data at a time. - DDR Memory - Double Data Rate memory (DDR) memory is based on the SDRAM (Synchronous Dynamic Random Access Memory) technology that uses the memory bus' clock signal to synchronize with the system bus clock speed.

Question 32

DDR operating voltages

Answer 32

- DDR = 1.8V or 2.5V - DDR2 = 1.8V or 1.9V - DDR3 = 1.35V, 1.5V or 1.65V - DDR4 = 1.05V, 1.2V or 1.35V

Question 33

Memory problems

Answer 33

- The system fails to boot and you receive a system beep code related to memory. - The system hangs or freezes. - Illegal operation or fatal exception errors occur. - General Protection Fault (GPF) errors occur. - The computer reboots randomly with or without BSOD. - Windows reports a memory problem.
