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.

List at least 4 things you can do if you receive memory errors during normal operation?
2) Make sure that the chips are seated correctly
3) Make sure that you are using the correct chips for your board
4) Enable boot logging to see if there are any specific errors during the boot process.
Answer 2- Remove and install the module
- Check that you have the right memory modules supported by your MOBO , verify thru CMOS
- Check that you have installed the right module size, as stated in MOBO documentation
- Remove the newly installed memory and check for error, switch memory sockets
- Clean the module edge connectors with a soft cloth or contact cleaner, blow or vacuum dust from memory slots
- Flash BIOS, BIOS might have problems with the new memory
- PG 295/296 Jean Andrews A+ book, good luck! :)
- remove and reinstall the module,
- check that you have the right memory modules supported by your motherboard,
- check that you have installed the right module size as stated in the motherboard documentation,
- and remove the newly installed memory and check whether the error message disappears.
2. Delete unwanted to unused programs or documents so save more memory
3. Defragment your PC/Laptop (will delete unused programs and more folders)
3 Main things.
How many 32K x 1 RAM chips are needed to provide a memory capacity of 256Kbytes?
A kilobyte (KB) is equal to 1,024 bytes. A megabyte (MB) is 1,024 kilobytes. So there are 1,024 KB * 256 = 262,144 KB in 256 MB
When a computer is first powered up it runs a "Power On Self Test" (POST). Many people call it a "POST test", but of course, that's redundant.
The POST runs through some basic systems, verifying that the computer is capable, at a very basic level, of running.
3 short beeps means that you have a problem with RAM.
RAM is VERY static sensitive. Your friend could have subjected the RAM to static electrical charges and not even known that he/she was doing it.
Remove the memory, put it in a static free container and take it to your local computer geek shop and have it tested. I'll include a link to a web site that lists the "Beep codes" and their meaning. http://www.computerhope.com/beep.htm
Which must be loaded first to a computer's memory the operating system or software?
Operating system must be loaded first so that other applications and programs will be able to work.
Two 512 mb ram is better or one 1gb ram?
1GB of DDR2 is definitely better. DDR3 is only a teeny tiny bit faster RAM. You'd barely
be able to tell in a benchmark test.
But to have double the amount, that's a huge difference.
DMA , IRQ and I/O address
DDR3 SDRAM stands for double data rate type three synchronous dynamic random access memory. It is used at the tempory memory a computer needs to operate. It is a faster version of the DDR2 RAM.
Meaning of the parts of the keyboard?
The meaning behind keyboard parts can regard to subjects. The actual components between the keys, switches and dials are one definition. The other definition depending on context are the number keys, arrows and letter, which indicate keyboard sections.
Is ddr3 ram compatible with Pentium 4?
It depends on the NorthBridge of the motherboard and the socket of the P4. Most intel-processor supported DDR3 Motherboard should be able to run a pentium, but remember that Pentium4 are very slow and DDR3 is still very immature. I recommend you to rather spend more money upgrading your CPU AND MOBO, rather than moving directly to DDR3.
Is there a way to wipe a computer hard-drive without destroying programs or program data?
The 'format' command will appear to erase the hard-drive HOWEVER - ALL it does is erase the reference track. The data will still be on the drive (and can be recovered). There are programs that will physically write either random characters or just zeros to every sector of the drive - over-writing all the data that was stored.
What is the difference between gigga bytes mega byte and tera byte?
1024 megabyte = 1 gigabyte
1024 gigabyte = 1 terabyte
A terabyte is MUCH bigger than a megabyte. Here is a break down of the sizes:
- Terabyte = 1024 Gigabytes
- Gigabyte = 1024 Megabytes
- Megabyte = 1024 Kilobytes
- Kilobyte = 1024 Bytes
- Byte = 8 Bits
- Nibble = 4 Bits
What is the Difference between secondary memory and auxiliary memory?
secondary memory is actually the permanent memory/the backing storage of the computer. it is of two types:
sequential access
direct access
auxiliary memory is the computer's internal/temporary memory. it is also of two types:
random access memory (RAM)
read only memory (ROM)
the difference between secondary memory and auxiliary memory is that:-
both are same i.e both performs the same operations
thanks.
How much MB of ram is in 1 GB of ram?
1 byte = 8 bits
1 kilobyte (kB) = 1024 bytes
1 megabyte (mB) = 1024 kB
1 gigabyte (gB) = 1024 mB
Basically, the 1024 comes from computers using the binary system
zettabyte, then yottabyte..
...so says another online source: http://www.chaaban.info/2006/11/02/what-comes-after-the-terabyte/
What is the function of the CD RAM?
The function of a CD to a computer is read only. A CD is used to view information stored on a computer and easily removed to transport to another location like sneaker netting. A CD-R is for reading and recording data that you do not wish to have saved only to the computer.
What are the four types of memory and their functions?
The few types of memory includes sensory memory, which deals with sensory information and stores visuals for few seconds. The other is short-term memory which recalls events or things happened over a perod of few seconds to few minutes, and then we have long term memory which deals with info over a larger period of time.
What are disadvantages of shared memory?
Interesting question. Most agree that shared memory should be minimized and that you should use IPC rather than shared memory if at all possible. Object Oriented programming suggests that an "Object" have it's own methods and that should be the only way that the data object should be modified. Shared memory tends to bypass that construct. In the current programming environment, shared memory is no longer recommended.
The portion of the internal bus that connects the processor to the memory cache is called?
Back-side bus(BSB)
800MHz and DDR2 is the assigned DIMM
What is one billion bytes called?
1,000 bytes, strictly doesn't have a name. A kilobyte is 1,024 bytes.
However, hard drive manufactures round this down to 1,000 bytes, so you can argue that 1,000 bytes is called a kilobyte.
Hard Drives that are advertised as 1TB drives often only have 1,000GB, not the 1,024GB they should have by definition... Always read the label!
Is memory a set of computer programs used ona computer to help perform tasks?
No. Memory is a physical component that temporarily stores on-demand digital data that is either being used by a program or transferred via a network connection to another computer (i.e. Random Access Memory or RAM).
Memory might also refer to the physical component used to store digital data for later access; the hard drive (HDD).
Virtual Memory is still physical memory in that it's a portion of the HDD allocated to assist the RAM in performing operations associated with the transfer of data.
Read only memory (ROM)
What is the SIC Code for Computer Storage Devices?
NAICS 334112 applies to Computer Storage Device Manufacturing.
What uses a portion of the hard drive as an extension of your physical ram?
Virtual Memory is using the Hard Drive as if it were RAM.
Cache is memory for frequently used things and is not stored on the hard drive.
