Computer Memory
The computer memory is a physical device used to store data or programs for use in a computer. Some types of computer memory include RAM (random access memory), ROM (read-only memory), and page cache.

What are the different types of ROM and RAM?
Some types are:
- Diode matrix ROM
- Capacitor matrix ROM
- Transformer matrix ROM
- Masked ROM
- one time programable ROM (e.g. fusible link ROM - nichrome or polysilicon)
- UVROM
- EEROM
- Flash ROM
- etc.
- SRAM
- DRAM
- Ferrite Core Memory
- NOVRAM
- Williams Tube CRT DRAM
- SGRAM
- SDRAM
- RAMBUS DRAM
- DDR DRAM
- etc.
Far too many to explain here, the subject would likely take several textbooks.
Can an acrylic stayplate be considered permanent?
Technically they are not supposed to be considered permanent. However, if you have government insurance (Medi-caid) and have teeth pulled, that is all they will pay for unless you are getting full dentures. And they usually don't pay to replace stayplates if they break. So, for a lot of people it is permanent, in the sense that they never get any other type of teeth, because the government always wants to do things as cheaply as they can. Dental Implants are probably the only thing considered permanent, and they are mega-bucks.
How can you improve your PC with a RAM of 190 MB?
Disk Defragmenter, Disk cleanup and a portable hard drive.
What does proactive interference of long-term memory means?
Proactive interference of long term memory can mean various things that effect ones future and past. Overall, this can mean that the memory is currently fading away.
What is the difference between Crucial BLS8G3N169ES4CEU and CT102464BF160B Laptop memories?
Looking at the two models, it seems that the only differences I can find are (1) the CT102464BF160B has a CAS Latency of 11 as compared to 9 in the other stick and (2) the only sources that I find for the BLS8G3N169ES4CEU are across the pond in the United Kingdom. Why that memory is offered only over that way is beyond me but that is just something I did notice.
For all intents and purposes, they are the same. Yes, the UK memory is slightly faster due to its lower CAS Latency but unless you are using some highly memory-intensive applications or games, chances are that you will never notice the difference.
My professional advice is to get whatever model is most commonly available where you are and don't sweat the difference between the two models.
Does primary storage consists of RAM and ROM chips?
Depends on what you mean by "primary".
Main memory is a term that mostly applies to RAM.
Primary memory can mean the same thing I guess.
Secondary storage usually refers to non-volatile devices, like a hard drive, which retain the digital data(bits)in sectors even when the computer is off.
ROM is a different story, and is usually burned program code sold as firmware that retains program instructions only closely tied to specific hardware or purposes, and usually doesn't change much, nor acts like a secondary storage device.
Does the Toshiba 1 GB DDR2 SDRAM work on laptops or desktops?
The Toshiba 1 GB DDR2 SDRAM works on laptops and desktops.
What does ALU use to hold data that is being processed?
It doesn't. Usually, the CPU general purpose registers provide input to the ALU, and the Accumulator receives the answer temporarily until it can be placed back into one of those registers.
Exactly how this is wired up varies widely with different CPU architectures, but in the theoretical model of an ALU, you specify which function you want, and the answer appears at the output as fast as the gates can operate. It is up to the CPU to store it somewhere.
What part of the computer where you install RAM?
the insdie part... right next to where the old ram is;;; on a laptop there is usually a little door on the bottom of it that you have to unscrew to put ram in
RAM and CPU requirements of the applications you typically use on your computer?
The RAM and CPU requirements of the applications you typically use on your computer will vary depending on the application. Most software will come with instructions and key requirements for installation.
What is Kingston valueram 2 GB 800mhz pc2-6400 ddr2 cl5?
It is a type of system memory, called RAM (Random Access Memory)
Kingston is the manufacturer, or brand
Valueram is the product line, or model
2 GB means 'Two Gigabytes', or 2,048 megabytes
800 MHz is the RAM's speed.
DDR2 is the technology, 'Double Data Rate 2'.
PC2-6400 is a way of repeating speed, type, and tech. PC2 means 'DDR2' and -6400 is the speed (6400 MB/s, or 800 MHz. 100 MHz = 800 MB/s for DDR2)
CL5 is the 'CAS latency'. This is how quickly the ram responds. It is a second method of measuring speed. The frequency (800 MHz) is the 'top speed', while the CAS latency is the 'acceleration'. What this means is that the computer needs 5 cycles to prepare every read or write, before it begins to do so (at 6400 MB/s). Lower CAS latency means faster response time. Generally, the frequency (MHz) is more important than CAS. But if you have two types of RAM with different CL and the same frequency (MHz), the one with the lower CL will be faster. CL5 and CL6 are standard DDR2 speeds. CL5 is considered 'good'.
How many bytes are in a megabyte'?
There are three definitions of megabyte (MB), two of which are commonly used in computing:
- 1000 × 1000 = 1,000,000 bytes in a megabyte - This is the standard SI definition, used for most media measurements (like hard drives and DVDs), for networking, and in some software (like Mac OS X and Linux).
- 1024 × 1024 = 1,048,576 bytes in a megabyte - This is the definition commonly used by memory manufacturers and in some software (like Microsoft Windows). The official term for this unit is "mebibyte" (MiB).
- 1024 × 1000 = 1,024,000 bytes in a megabyte - This definition was used in the once-common "1.44 MB" floppy disk, and is usually considered a mistake
Who loads bootstrap program in memory and when?
When the computer start all the essential files, to start the operating system load from disk to the memory.Basically the bootstrap program is loaded into the read only memory(ROM) which enables while the computer start.
What is the term for when new memories impair the retreival of old memories?
If i understand correctly e believe it's called Deja Vu. I might be wrong thou.
Can you transfer a used 512mb memory block from your old computer to your new computer?
If you mean RAM. then you may transfer it, but the new motherboard must support the same type of RAM.
How does RAM relate to the system bus and clock?
Dunno for sure but RAM is what the computer uses to perform all of its functions simotaneously and the more RAM ur comp computer has the faster you will see things like, overall programs speeds. 1GB is the REAl minimum for good computer experiences
