What are the advantages of using RAM?
The Major advantage of using RAM is that your programs will load much faster. Like if your decided to upgrade your RAM from 128MB to 1GB of RAM you will notice that your games will load faster as well as your applications that you are running. On top of that, you would be able to run multiple applications at the same time without having that annoying skip and pausing, etc. Like you could listen to I-tunes flawlessly while doing a 3-D drawing in AUTO CAD. However, even though your programs, applications and games load faster, it does not mean that your computer will run smoother because you did not upgrade your graphics card. But, that is in entirely different topic.
No, DRAM is dynamic and thus stores its data as charge in capacitors. These capacitors are always discharging, so without refresh (i.e. read and rewrite every bit of data) periodically all the data in the DRAM will simply vanish. The operation of refresh requires power.
DRAM is very volatile.
What technology uses battery power to retain information even when the power to the computer is off?
complementary metal oxide semiconductor random access memory
A form of static random access memory built using both N-channel and P-channel metal oxide semiconductor field effect transistors, to keep the data hold current draw in the microampere range (or smaller) when not being accessed.
Does RAM matter in the case of the brand type?
In terms of which brand of RAM, it does mostly matter, depending on what computer it is to be installed in. For basic tasks, PNY and Crucial are good brands for the money, keep in mind they won't perform as well as something like G. Skill or Corsair.
The first true RAM, Williams Tube CRT DRAM, was invented in 1946 and built in 1947 for use on the Manchester Baby experimental computer. It was 32 words of 32 bits each. Larger versions soon followed, typically about 1K words in size.
Which computer memories has the shortest access time?
Usually the register set memory. The L1 cache may be as fast.
What are the new age memories of computer?
the new age memories are the memory devices which are modernly used for storing the data such as pen,thumb,flash drives,memory sticks,blue ray discs,etc.
The new generation computer and laptop memory is DDR4
Disk Caching.
What are the three major activities of an operating system with regard to memory management?
1- keeping track of which parts of memory are currently being used and by whom.
2- decide which process is to be loaded in memory when the space is available.
3- allocate and deallocate memory space as needed.
How many register in 2K memory chip?
Registers represent the number of memory locations. A 2K memory chip has 2x1024=2048 memory locations. Hence there are 2048 registers in a 2K memory.
How many bytes make 2kilobytes?
1 MB (megabyte) has 1000 kb (kilobyte).
1 GB (gigabyte) has 1000 MB (megabyte).
So, 1 GB (gigabyte) has 1000x1000=1,000,000 KB (kilobytes)
Hope This Helps You!
That depends on the memory architecture of the system.
- if the memory chips are byte wide and not used to create a multibyte bus, 11 address bits are needed.
- if the memory chips are 32 bits wide, 9 address bits are needed (with the CPU internally selecting which of the 4 bytes it will use).
- it the memory chips are 64 bits wide, 8 address bits are needed (with the CPU internally selecting which of the 8 bytes it will use.
- if the memory chips are 4 bits wide, 12 address bits will be needed and the CPU must perform 2 memory cycles per byte that it needs. (yes, I have seen a computer that worked this way!)
- etc.
How many megabytes are in a gigabyte?
This definition is used in hard drives, portable memory drives (memory cards, USB drives), DVDs, Blu-ray disks, and most measures of performance. Some software (such as Mac OS X and the Linux kernel) uses this definition when displaying file and disk sizes.
MB stands for megabyte. Mb with lowercase b is ambiguous, as it has been used for both "megabyte" and "megabit". Writing megabytes as MB and megabits as Mbit avoids any confusion.
Memory manufacturer definitionAnother definition is used by memory manufacturers and some software, like Microsoft Windows. They use 1024 (210) megabytes per gigabyte, but this is more properly called a gigabinary byte(GiB), sometimes contracted to gibibyte.Using the non-standard definition:
- 1 megabyte (MB) = 1024 kilobytes (KB)
- 1 gigabyte (GB) = 1024 megabytes (MB) or 8192 megabits (Mb)
- 1,000 megabyte (MB) = 1 gigabyte (GB)
- 1,024 mebibyte (MiB) = 1 gibibyte (GiB)
- 1 megabyte = 8 megabits
- mega- = 1,000,000
- giga- = 1,000,000,000
- mebi- = 1,024 × 1,024 = 1,048,576
- gibi- = 1,024 × 1,024 × 1,024 = 1,073,741,824
What is the difference between single port ram dual port ram and pseudo dual port ram?
The difference between single port RAM and dual port RAM is that single port RAM can be accessed at one address at one time, thus you can read/write only one memory cell during each clock cycle. Dual port RAM has ability to simultaneously read and write different memory cells at different addresses.
SPRAM uses a 6 transistor basic ram cell, while the dual port ram cell uses 8 transistor cell for memory. so the area of spram is much smaller than the area of dpram cell. To gain the advantages of both spram (less area) and dpram ( high speed) Pseudo dual port ram is introduced. which can read and write the data in the same clock, using rising and falling edges for the operations respectively, and using spram memory cell for the storage of data.
To unblock a USB port, simply click on the 'start' menu. From there, go to 'my computer', 'system tools', 'computer management' and then find the USB port in the list. From there, right click the icon and click 'enable'.
Why does a 2001 dodge ram have 8 wires running to the trailer plug when only 7 are needed?
Is there an extra connection for a rear power outlet? I think so.
The extra hot wire in your trailer plug is for your camper if your towing one. This charges the camper battery while your driving and can discharge your truck battery if you leave it connected and are drawing on your camper electrical system. I found this out the while I was switching my trailer plug and found I had an extra hot wire. The fuse for this is either in the fuse box with the others or if it was added after production is in line at the left front fender corner.
How do you put a larger hard drive in and put old info on it?
Assuming it is an IDE drive, there are two IDE slots - Primary & Secondary. Each slot can hold two drives, Master & Slave, which are configured by jumper settings on the disk drive.
You have two options.
OPTION ONE: Start a brand new installation on the new drive. Reinstall the OS and all your software, then add the old drive as an additional drive. Your old data is then available to copy across.
This sounds drastic, but it has the advantage of cleaning up your PC, getting rid of old / corrupted no longer used files.
Remove old drive (otherwise the old OS will be detected). Install new drive as Primary-Master. Reload Windows Configure old drive as either "Primary-Slave" or "Secondary-Master". This will probably depend on where your IDE cables reach. If the new drive has room, I would copy the old drive across into "C:\old drive" and keep the old drive in a cupboard as an emergency backup. Carry on reinstalling.Your old data will be available in "C:\old drive" or on your "D:" or "E:" drive. nb Do not format or delete files from your old drive until everything is working again. (In an emergency, it will still be available for booting). Caveat: Reloading data into some software may require some degree of computer knowledge. It may not be a simple case of copying over files.
OPTION TWO: Duplicate the drive using software such as "Partition Magic" or "Norton Ghost". This involves an expense, but saves having to reinstall.
Install new drive as "Primary-Slave" or "Secondary-Master". Load "Partition Magic". Duplicate the existing drive onto the new drive. Increase the partition size on the new drive to its maximum. Configure new drive as "Primary-Master". Remove old drive. Boot up. You should get your old system back, but with much more disk space. The old drive can be stored as a back up, or added later as a "Primary-Slave", "Secondary-Master" once the system is proved to be working.
Just to clarify the above answer... Partition Magic won't clone a disk but Drive Image Pro (by the same company) will. I prefer Ghost. See if your IT people at work can assist you if they use a cloning program.
Alternate Software OptionI would like to mention an additional software tool that I have found to be easier than Ghost. Acronis True Image is awesome for swapping the hard drive or even when you upgrade the CPU and motherboard. It has a Universal Restore option that will allow you to reimage your entire Windows environment (applications and all) to a brand new machine. It is pretty affordable at $29.00 or so.What is the use of virtual memory?
Virtual memory is used to increase the size of working memory in the system main memory by using the locations in secondary storage such as harddisk.
What does it mean when a computer says the ECM on Dodge Ram is bad?
THAT WOULD MEAN THAT YOUR "EMISSION CONTROL MODULE" IS BAD AND YOU NEED TO GET A NEW ONE. YOU CAN ASK ANY PARTS STORE FOR INFO ON WHERE YOUR'S IS LOCATED, MINE WAS ON TOP OF THE ENGINE. BUT THATS A CHEVY! COLLEEN S.
Yes it is hard to visualize but yes, the CPU does everything from mundane things like fetch the lastest game to biometric physics...But CPUs are built for different jobs. The data is put in "Registers" inside the CPU. These registers act like work benches to organize what needs to be done first. There is a register for normal processing and a Register for math computations. This is called the Arithmetic Logic Unit. Those work together moving billions of line of code a second..hope this helps. Answer: CPU
