38
Q

What is PROM? 1.1.2.4

A

Programmable read-only memory. Information is written to a PROM chip after it is manufactured. A PROM chip cannot be erased or re-written.

39
Q

What is EPROM? 1.1.2.4

A

Electrically erasable programmable read-only memory. Information is written to an EEPROM chip after it is manufactured. EEPROM chips are also called Flash ROMs. An EEPROM chip can be erased and re-written without having to remove the chip from the computer.

41
Q

What is DRAM? (RAM TYPE) 1.1.2.5

A

Dynamic RAM is a memory chip that is used as main memory. DRAM must be constantly refreshed with pulses of electricity in order to maintain the data stored within the chip.

42
Q

What is SRAM (RAM TYPE) 1.1.2.5

A

Static RAM is a memory chip that is used as cache memory. SRAM is much faster than DRAM and does not have to be refreshed as often. SRAM is much more expensive than DRAM.

43
Q

What is FPM Memory? (RAM TYPE) 1.1.2.5

A

Fast Page Mode DRAM is memory that supports paging. Paging enables faster access to the data than regular DRAM. FPM memory was used in Intel 486 and Pentium systems.

44
Q

What is EDO Memory? (RAM TYPE) 1.1.2.5

A

Extended Data Out RAM is memory that overlaps consecutive data accesses. This speeds up the access time to retrieve data from memory, because the CPU does not have to wait for one data access cycle to end before another data access cycle begins.

45
Q

What is SDRAM? (RAM TYPE) 1.1.2.5

A

Synchronous DRAM is DRAM that operates in synchronization with the memory bus. The memory bus is the data path between the CPU and the main memory. Control signals are used to coordinate the exchange of data between SDRAM and the CPU.

46
Q

What is DDR SDRAM? (RAM TYPE) 1.1.2.5

A

Double Data Rate SDRAM is memory that transfers data twice as fast as SDRAM. DDR SDRAM increases performance by transferring data twice per clock cycle.

47
Q

What is DDR2 SDRAM? (RAM TYPE) 1.1.2.5

A

Double Data Rate 2 SDRAM is a faster than DDR-SDRAM memory. DDR2 SDRAM improves performance over DDR SDRAM by decreasing noise and crosstalk between the signal wires.

48
Q

What is DDR3 SDRAM? (RAM TYPE) 1.1.2.5

A

Double Data Rate 3 SDRAM expands memory bandwidth by doubling the clock rate of DDR2 SDRAM. DDR3 SDRAM consumes less power and generates less heat than DDR2 SDRAM.

49
Q

What is RDRAM? (RAM TYPE) 1.1.2.5

A

RAMBus DRAM is a memory chip that was developed to communicate at very high rates of speed. RDRAM chips are not commonly used.

50

52
Q

What is DIMM (Memory Module) 1.1.2.6

A

Dual Inline Memory Module is a circuit board that holds SDRAM, DDR SDRAM, DDR2 SDRAM, and DDR3 SDRAM chips. There are 168-pin SDRAM DIMMs, 184-pin DDR DIMMs, and 240-pin DDR2 and DDR3 DIMMs.

53
Q

What is RIMM (Memory Module) 1.1.2.6

A

RAMBus Inline Memory Module is a circuit board that holds RDRAM chips. A typical RIMM has a 184-pin configuration.

54
Q

What is SODIMM (Memory Module) 1.1.2.6

A

Small Outline DIMM has a 72-pin and 100-pin configurations for support of 32-bit transfers or a 144-pin, 200-pin, and 204-pin configurations for support of 64-bit transfers. This smaller, more condensed version of DIMM provides random access data storage that is ideal for use in laptops, printers, and other devices where conserving space is desirable.
