What type of DIMM supports triple channeling?
DIMM is a type of computer memory for your computer, and it supports certain types of channeling. DIMM 1, 2 3, and 4 supports some types of dual channelling.
What is a type of computer memory that can be accessed randomly?
Of Course. RAM= Random Access Memory, so yes, you CAN randomly access your RAM... And you Probably ARE RIGHT NOW!
What is the function of the program counter register?
The function of the program counter register is to hold the address of the instruction that is being executed and (later) to hold the address of the instruction that will be executed next.
Where do you plug a memory card in a computer?
you will need a card reader to connect your memory card in a computer, card reader can be plug in a USB port.
How do you reset the computer on a 1996 Dodge Ram?
Take it to auto zone or orielly part store something similar to that and have them use the machine that plugs in under the dash and select reset code. One other thing u might try is unplugging the battery for a half hour to force reset the computer. goodluck.
Which the largest kilobyte gigabyte megabyte or terabyte?
From largest to smallest: Terabyte, gigabyte, megabyte, kilobyte.
Looking at the prefix of the word will give you the answer. "Kilo" means 1000. "Mega" means one million. "Giga" means one billion. This prefix system is commonly used in the metric system as well, so feel free to read more about it.
What is the general relationship among access time memory cost and capacity?
Faster access time, greater cost per bit; greater capacity, smaller cost per bit; greater
capacity, slower access time.
As a general rule (but there are exceptions) the greater the capacity of a memory the longer the access time. For a higher cost the access time of a given capacity memory can usually be shortened some.
As a general rule (but there are exceptions) the greater the capacity of a memory the total memory cost increases, but the memory cost per bit decreases.
How many bits in 20 mega bytes?
1 Bit is the smallest recordable state ( Zero or One / ON or Off / High or Low ) 1 Byte is 8 Bits which can represent a number upto 256 ( 2**8) or a character 1 KiloBytes (KB) is 2**10 Bytes == 1024 Bytes //// "Slang" as One Thousand 1 MegaBytes (MB) is 2**20 Bytes = 2**10 * 2**10 Bytes 1,045,876 Bytes //// "Slang" as One Million 1 GigaByte (GB) is 2**30 == 1,073,741,824 //// "Slang" as One Billion So 20 Gigabytes is 20 * 2**30 Bytes 1 TeraByte (GB) is 2**40 == 1,099,511,627,776 //// "Slang" as One Trillion From the above, you can see why a 32 bit operating system can address upto 4 GB of memory (2**32 4GB if your computer has 4GB of RAM and a 32 bit OS, it will not be able to address it all since some of that address is used by video cards and other devices. This is why most PCs have either 3GB (or less) with a 32 bit OS or MORE & MORE ( 4+GB with 64 Bit OS)
How many 30-pin simms are installed in one bank?
30-pin SIMMs are installed in groups of four. SIMMs in each group or bank must be the same type and size.
How many terabytes are in one petabyte?
There are 1000 terabytes (TB) in a petabyte (PB). There is an older definition based on multiples of 1024 instead of 1000, but this was changed, and tebibytes and pebibyte are the ones based on multiples of 1024.
Computer Manufactures consider it being 1000. But the OS will say 1024 (due to the binary numbering).
Here is the memory ladder according to computer manufactures
- 8 bits= 1 Byte
- 1000 bytes= 1 Kilobyte
- 1000 Kilobytes= 1 Megabyte
- 1000 Megabytes= 1 Gigabyte
- 1000 Gigabytes= 1 Terabyte
- 1000 Terabytes= 1 Petabyte
- 1000 Petabytes= 1 Exabyte
- 1000 Exabytes= 1 Zettabyte
- 1000 Zettabytes= 1 Yottabyte
Here it is according to binary prefix and the older numbering system:
- 8 bits= 1 Byte
- 1024 bytes= 1 Kilobyte
- 1024 Kilobytes= 1 Megabyte (1 048 576 bytes)
- 1024 Megabytes= 1 Gigabyte (1 073 741 824 bytes)
- 1024 Gigabytes= 1 Terabyte
- 1024 Terabytes= 1 Petabyte
- 1024 Petabytes= 1 Exabyte
- 1024 Exabytes= 1 Zettabyte
- 1024 Zettabytes= 1 Yottabyte
What is the random operating memory?
There is no such thing.
random access memory maybe? RAM
ROM = Read Only Memory, not Random Operating Memory.
The ________ is the essential component of the operating system that remains in RAM when your computer is powered on.
See this answer : http://wiki.answers.com/Q/What_is_the_difference_between_primary_memory_and_secondary_memory
What is the process of loading a process secondary memory into primary memory?
The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage.
What ports are available on desktop computers?
Ports are something where you can connect output devices and other devices.
Here is a list of different ports you can have:
USB ports
SD card reader port
SATA ports (located on the motherboard)
What does the cache memory do in accessing data?
Generally, there isn't. Specifically, you got a shot. Here's what I mean.
Cache - Stores minor information in your system from website's such as log-in information, what pages you visited, and what products you looked at. It also saves information pertaining your applications (software) window size and location. Cache is stored in Temp folders, although it is pointless to access this. If you are wanting to clean your Cache, I always recommend CCleaner, I've been using it for years.
"BIOS is stored on a ROM (Read Only Memory) chip, however, the data in the ROM chip can be changed. Its called flashing BIOs. It is done with software."
^You did not answer the question. He asked the "type" of ROM. EEPROM is the type of ROM that is able to be reprogrammed while physically installed in the computer.
ddr3 can achive much higher clock rates than ddr2. the highest possible clock speed of ddr2 is 1333MHz while there are already 1800MHz ddr3 sticks being produced. also ddr3 can support twice as much capacity per stick than ddr2. Answer DDR3 in several significant ways: * Higher bandwidth due to increased clock rate * Reduced power consumption due to 90mm fabrication technology * Pre-fetch buffer is doubled to 8 bits to further increase performance
What is the largest unit of imormation Kilobyte gigabyte megabyte terabyte?
1000 KB = 1 MB, 1000 MB = 1 GB, 1000 GB = 1 TB
The answer is Terabyte.
What is the function of DDR in computers?
Depending on it's context, 'DDR' can have several meanings.
Double Data Rate (refers to the transfer rate of computer memory)
Dance Dance Revolution (a video game)
Deutsche Demokratische Republik (was known in the US as East Germany)
Direct to Disk Recording
What are all the types of bytes?
A bit is one unit of data, a yes or no, an on or off.
8 bits is one byte.
1024 bytes is one kilobyte
1024 kilobytes is one megabyte
1024 megabytes is one gigabyte
1024 gigabytes is one terabyte
1024 terabytes is one petabyte
1024 petabytes is one exabyte
1024 exabytes is one zettabyte
1024 zettabytes is one yottabyte
(they have just perfected the terabyte for the computer)
I can answer this de jure or de facto.
The definition most people refer to is just how many pictures your internal storage or flash card can store. For example, 8GB of photos on my CF card.
The proper definition of memory capacity is the internal RAM of any device which handles files as they're being processed. Think of it this way.. the processor is good at adding numbers, but can't remember any. If I tell you 2+3 your brain knows how to do addition, but what if you can't even remember the numbers "2" and "3"? That's what memory is for. In a camera this is often called an image buffer because you can take a few photos and even if they aren't stored permanently they can be in "limbo" in the camera and not be lost.
What kind of material is used to make HDD platters?
Platters made from several material ferromagnetic and nonmagnetic material which are:
1 : perpendicular material cobalt and platinum and Cr
2: coated material Al2O3
Weight of platinum about 10 % to 35 %
