Computer Memory

That is approximately a Gigabyte. The prefix Giga normally means a billion, but in computer science, and specifically for data storage, it is often taken to be 10243. The difference is about 7%.

They are installed in groups or banks of two. Most older motherboards that use SIMMs have one to three banks that can be filled with two, four, or six SIMMs. 72-pin simms are installed into groups or banks of two

ROM, is Read Only Memory. It is a secure chip on which the manufacturers have burned data the computer needs in order to boot up the Operating System. It is not affected on losing power. RAM, on the other-hand, is Random Access Memory, and is very volatile, losing any data held in memory on powering down.

there are several answers i could come up with for this one, depending on the OS you use, many systems use empty hard disk space and convert that into what is called "virtual memory." so systems use both, actual memory installed, and virtual "paged" memory. so to simplify the answer, the more memory you have, the less time programs have to use your hard disk "memory" to finish, or run tasks. when your drive is being accessed for memory, it takes away access time for applications. The limiting reagent model: your system can only go as fast the the slowest reagent. Information moving from memory to CPU - fastest, speed of current Information moving from Hard drive to CPU - slowest, friction of drive turning to access information More memory means more information can be stored electronically and be accessible electronically. Of course, all of this must take into account your OS and how the program you want to run is coded. If the program will not load into memory but constantly accesses the hard drive by design, more memory will not help it so much. More memory really comes into play with the processes behind the scenes in Windows. By having more space for Windows XP to run free, you allow necessary functions to flow quickly.

I presume you are refering to your PC.(I also presume you are not refering to the four legged type of Ram)

on your desktop left double click the my computer icon.in my computer left double click the Control Panel icon.Left double click the System icon (it looks like a PC screen)

This will access the System Properties info.In the general section you should see the makle of PC and the supplier of the chips i.e Pentium and any other info regarding the system you might need.

The set up files folder on the computer can be found on the desktop. Any folder in the All Files section can be synced into this folder.

1) Redundancy: a failure in a single 256MB is critical where as a failure in either 128MB module leaves you at half capacity.

2) Speed : accessing two separate devices is usually quicker than accessing a single device.

However up sides to the single module is usually cost and free slots to expand further.

short-term memory.

You need 12 address lines to access 4K of memory. 212 = 4096. log2 (4096) = 12.

Depends on what type of PC you have what operating system you're using and how much you do on you're PC. ( Open windows / Programs / Processes Running )

Swapping files from virtual memory back to RAM is known as multitasking. When a computer with an insufficient amount of RAM uses its virtual memory too often, it can cause the computer to enter Safe Mode.

Your Computer will have come with a set amount of memory when you bought it.

However if that set amount of memory is not enough for you, then one of the things that you can do is to install more and/or a bigger hard drive.

But there is a much more simple option: Buying an external Hard drive is the defiantly the most simple option. These can store from 100GB to 1TB.

Random access memory (RAM) is memory that can be written to easily (which usually means by the device where the memory's installed). "Random access" means any part of the memory can be got at immediately.

RAM needs to be supplied with power to keep what's in it. ROM (Read Only Memory) doesn't, but writing to it is more difficult - you usually need a separate writer.

Random access memory is more commonly said as RAM. Random access memory or RAM is what some of the speed of your pc or laptop comes from. RAM Looks like a long chip that goes inside your computer and it comes in gigabytes and most computer have 2 RAM slots so E.G. my laptop has got 4gbs of RAM. it has to 2gb sticks. there are about 10different RAM stick ones with 200 pins, 204pins, 240pin etc.

it means that the memory cannot be earased

When you are buying RAM, remember to check how much your computer can handle first. How to do this depends on what system you are using.

Also remember that for your computer to handle RAM better, divide it evenly. If you want to get 1GB, get two 512MB sticks. If you want to get 2GB, get two 1GB sticks, and so on. This way it will be easier for the computer to handle it.

The cost of RAM depends on A) What brand you get and B) What size you get. The brand really does not matter. People will try to tell you "Get this brand! It's so much better than this other brand!" But it's really not. A brand is just a name. Shakespeare said "A rose by any other name would smell as sweet."

4. List five steps, how application programs transfer in and out of RAM.

The RAM slot on Dell laptops is located at the bottom of the computer, usually it is marked with an 'M' for memory. I found a great video on how to replace the RAM yourself. It is really easy, and it improves the performance of your computer immensely.

Contiguous memory allocation scheme suffers from external fragmentation as address spaces are allocated contiguously and holes develop as old processes die and new processes are initiated. It also does not allow processes to share code, since a process's virtual memory segment is not broken into non-contiguous fine-grained segments.

Pure segmentation also suffers from external fragmentation as a segment of a process is laid out contiguously in physical memory and fragmentation would occur as segments of dead processes are replaced by segments of new processes. Segmentation, however, enables processes to share code; for instance, two different processes could share a code segment but have distinct date segments.

Pure paging does not suffer from external fragmentation, but instead suffers from internal fragmentations. Processes are allocated in page granularity and if a page is not completely utilized, it results in internal fragmentation and a corresponding wastage of space. Paging also enables processes to share code at the granularity of pages.

The RAM (random access memory) usually stores temporary files and cache to help speed up your computer by not having to repeatedly load the same thing but is you do not restart your computer the RAM will become full and it will slow down your computer so every now and then just restart the computer for best performance.

The Random Access Memory (RAM) chip is volatile, and any data not saved to the hard drive will be lost on switching off the computer.

== == In Windows XP: Go to Start -> Settings -> Control Panel -> System. The main page shows details of your computer, including the processor type and RAM.

On any Windows machine, you can also run one of the good free utilities like CPU-Z that provide you with information on your processor subsystem and memories in detail. See the Related Link.
