Q

What is the RAM connected to?

A

The memory controller in the northbridge chip or the CPU itself

20
Q

The memory bus is a series of electronic circuitry that provides three functions:

A

data, address, and control.

21
Q

Performs management functions such as specifying the memory’s clock signal, and telling the memory module if the operation is a read or write.

A

The control bus

22
Q

A 32-bit module that has memory chips on one side of the package. Only used on very old computers, and frequently must be installed in matched pairs

A

SIMM: A single inline memory module

23
Q

A 64-bit module which can have memory chips on one or both sides of the package. Depending on the system they might be installed alone, in pairs, or even in larger sets.

A

DIMM: A dual inline memory module

24
Q

A smaller memory form factor typically used in laptops and SFF PCs

A

SODIMM: A small outline dual inline memory module

25
Q

A trademarked term for memory modules used by Rambus memory. 64-bit modules much like DIMMs, but slightly smaller.

A

RIMM

26
Q

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

A

ECC (error-correcting code) Memory

27
Q

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

A

DDR4

28
Q

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

A

DIMM

29
Q

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

A

SODIMM

30
Q

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

A

SIMM

31
Q

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

A

RIMM

32
Q

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

A

Advanced Configuration Power Interface (ACPI)

33
Q

Controls what happens when the computer doesn’t shut down properly or it goes into, or awakens from, a misconfigured Standby or Hibernate mode

A

The BIOS/UEFI power management settings

34
Q

Security features that might be included with your BIOS/UEFI include:

A 
BIOS/UEFI passwords
Hard drive encryption
Secure boot
Trusted platform module (TPM)
LoJack
35
Q

Prevent unauthorized changes to both a computer’s BIOS/UEFI settings and hard drive data

A

BIOS/UEFI security features

36
Q

Uses 1.8 V to operate and fetches 4 bits of data per clock cycle (twice as fast as DDR)

A

DDR2 SDRAM

37
Q

Uses 1.8 V to operate and fetches 2 bits of data per clock cycle

A

DDR SDRAM

38
Q

Uses 1.5 V to operate and fetches 8 bits of data per clock cycle

A

DDR3 SDRAM

39
Q

Used primarily in older AGP 2x/4x low-end video cards and chipsets and transfers 1 byte of data per clock cycle and uses 1.8 V to operate.

A

SDRAM

40
Q

How many pins in Dual inline memory modules (DIMMs)

A

168 pins. Some DIMM designs have 72 or 144 pins. Known as SODIMMs. Normally used in portable computers.

41
Q

Where is Buffered Data stored?

A

RAM

42
Q

How many pins in Single inline pin packages (SIPPs)

A

30

43
Q

How many pins in single inline memory modules (SIMMs)

A

30 or 72 pins

44
Q

How many pins in dual inline pin packages (DIPPs)

A

16 pins

45
Q

Acquire wide recognition with the release of computers that use Intel’s Pentium III processor. This type of RAM requires that all available memory slots be filled, creating a need for continuity chips in otherwise unused slots.

A

RDRAM (rambus dynamic random access memory)
