Is any long-term data stored on ram?
Not unless you power it permanently. RAM can only store data as long the power is turned on.
How much memory does the average computer hold?
It depends on how large your hard drive's capacity is. A 1TB (terabyte) hard drive can store 1,000GB (gigabytes), 1,000,000MB (megabytes), 1,000,000,000KB (kilobytes), or 1,000,000,000,000B (bytes) of data.
What is the smallest unit in a computer's memory?
A bit, which can hold two values. 1 bit is the smallest unit of info in a computer 4 bits = 1 byte 2 bytes = 1 word a "byte" can be all sorts of things: It usually is the smallest addressable unit in a computer. 8 bit bytes are the most common nowadays, but here are, or have been, computers with bytes of 4 bits, 8 bits, 9 bits, 13 bits, 16 bits and others.
The smallest amount of data that can be stored on a computer is a byte. A byte is one character, whether a letter or number. Computers store data in numbers, mostly 0's and 1's, which represent on and off.
A 32-bit processor can perform functions on 32-bit pieces of information. The value of that 32-bit number may only be 1 bit, but the computer processes it as if it were 32-bits.
What is computer circuitry that temporarily holds data waiting to processed known as?
The Ram - Random Access Memory temporarily holds programs and data while the computer is on and allows the computer to access that information randomly.
Vm-ware is the software allows us to install 2 O/S in your PC. Then we can use both operating systems by minimizing the window. It allows to use parallel Operating systems. sorry if the answer is not right.
How many pins are on a sdram dimm on a ddr dimm on a simm on a rimm?
168 pins are used on SDRAM DIMM. 184 pins are used on DDR DIMM. There are either 30 pins or 72 pins used on SIMM. 184 pins are used on RIMM.
The EDO RAM desktop memory modules have 72 pins and operate at 5V as standard
Which chip enables the CPU to interact with RAM?
Both the CPU and the memory (RAM) are connected to a massive circuit board called the motherboard. Internationally it is sometimes called a mainboard.
The motherboard is made up of layers and groups of copper wires that are used to transmit information. One group of these wires will be dedicated to a task. For example, there is a group dedicated to moving information from RAM to the CPU. We call each group a bus.
Buses are the reason why the metaphor of a "data highway" is sometimes used. There are many types and sizes of buses used for different needs. Memory access has one kind, disk access has another kind.
Depending on the type of CPU and type of RAM you will have a unique bus design that allows the CPU to communicate with the RAM.
This is why RAM for new computers has more pins (bigger bus) and a higher bus speed than RAM for old computers.
Can you take RAM from one computer and put it in another?
Provided that the RAM types are compatible.
Understand that RAM does not retain information when the computer is turned off, and there will be no information on the RAM when you turn on the computer.
A byte is the common term for a single character in a computer. It's comprised of 8 bits (0 or 1), which in binary (the base system of any computer) can be any number from 0 to 255. The computer then interprets the number as it's associated character.
What are the functions of primary memory?
Primary memory also called main memory is normally the Random Access Memory (RAM) of the computer. It is the memory that the Central Processing Unit (CPU) can access directly. All data and program instructions are stored and retrieved by the CPU from the primary memory in small block normally from 1 to 8 bytes at a time. The CPU can not store or retrieve anything from the permanent storage locations such as hard drives, jump drives, diskettes, etc. Therefore data on permanent storage is retrieved from the storage device in large blocks, normally 512 to 65536 bytes at a time, and written to the primary memory where it is then used by the CPU. When it is time to save the data or programs from the primary memory to a permanent storage location it is written again in large blocks to the device.
What does additional RAM improve on your computer?
Increasing your RAM will make a major difference. Each program you run requires a specific amount of RAM usage at one time. The more RAM a user has will cause the computer to run more smoother, and should make programs open up faster. Each RAM stick has a sector that holds all physical activity, so increasing the RAM will make the RAM usage not switch as often since you'll have more to use.
Another answer:
Actually, it depends. Increasing RAM will only help things indirectly unless you were very low to begin with. What RAM does is allow more information to be held in memory so the hard drive won't have to be accessed as much. If you are after speed, upgrading the processor chip should help. More RAM and a faster hard drive should also.
As you know, the brain is a muscle and if you don't use it you lose it. It's important to keep your mind active like playing chess with one friend; cards with guests (on occasion) even taking a hobby up or take a night course on something you are interested in. If you enjoy the computer then play games on the computer (ones you have to think about.) Even working on this board is good "brain exercise" and you learn much on top of it all.
Some people may have short term memory out of habit from the environment they grew up in, while others may suffer from certain diseases that cause this. Also some medications can create short-term memory. Stress is also a factor for not being able to remember things well or missing appointments, etc. Perimenopause and menopause in women will cause this temporarily and "Andropause" (once called mid-life crisis) in men may cause this. The dark dreary days of winter can certainly cause the brain to feel sluggish. I live in beautiful British Columbia (it got that way from all the rain) and although today is a beautiful sunny day we have to put our sunglasses on! LOL We can have weeks of dreary wet weather and people feel lethargic and have what we refer to as "blond moments." LOL I try to keep busy with my work off the computer, on this board, and also my artwork and other projects I'm in the midst of as I've had Interior Decorating experience so love to work on the inside of my home during these miserable days and then I'm more active in the spring and summer. Taking long walks, doing Tai Chi, going to the gym and on occasion swimming. For quiet times and to get myself centered it's Tai Chi, gardening, fishing and camping.
Believe it or not a good exercise for the brain is Crossword Puzzles (start out with the mid-range ones or even the easier ones and work up.) I've done this for years and still do it when I'm waiting in an office for an appointment.
Good eating habits is a must and 3 1/2 ounces of protein at each meal for a woman and 6 - 8 ounces of protein for a man at each meal is the amount of protein needed for the brain and other organs to function. Exercise is right at the top of the list to keep the heart in good shape because it pumps oxygen to all organs including the brain. Jogging, biking, swimming, or working out at the gym. Golf is good to lower the stress level or fishing and camping. Getting back to the good old earth such as gardening is also helpful. Getting back to nature basically.
During stressful times (which most of us can have) it's important to simply write appointments on a calender or mark it in a daily journal (I use this all the time.)
In many cases for certain individuals it's just bad habits and they are lazy. In other words, "Let someone else remember all my appointments, etc.) My husband came from a family of bad habits, so when home he conveniently can have short-term memory. Instead of remembering for him I put up a calender in the kitchen right where he eats breakfast and gave him another habit .... look at the calender to see what appointments he may have that week! It took about a month, but he's on his own and doing well. I refuse to remind him unless he's had long and hard days at work. I also get him make his own appointments, do the odd bit of grocery shopping and some banking only because if something happened to me he would know how to do all these things properly. He relied on me too much because my memory is quite good and I'm 65. It makes him feel more responsible and also doesn't make him feel like he's growing old which we can all feel at times once one passes 40.
If you are into Homeopathic medicines then go to a good Homeopathic doctor and ask them if they can help to keep your brain active. Be sure your doctor is informed of whatever the Homeopathic doctor gives you so he can mark it on your file. Although Alzheimer's and Dementia (a close relative of Alzheimer's) can strike anyone of us (could be genetic) one can ward off much of this if they do keep their mind active.

What is the average memory of RAM in a computer?
Most computers in 2008 come with at least 1 GB (even laptops). You should get around 2 GB if you're going to do alot of work on the computer such as editing photos or editing videos. However, for a casual user who is surfing the web or using MS Word/Excel, even 512 MB would be enough.
What unit of memory stores 1024 kilobytes?
There are 1000 kilobytes in 1 megabyte, but a common misinterpretation is that there are 1024 kilobytes in 1 megabyte.
Most things are measured in 1000s (like hard drives, internet speeds, etc.), but memory is measured in 1024s due to the binary addressing.
- 1024 kibibytes (KiB) = 1 mebibyte (MiB)
- 1000 kilobytes (kB) = 1 megabyte (MB)
What is the full meaning of RAM?
The full form of RAM is random access memory. Ram is volatile. Volatile chips don't hold the same data. Program and data can be written to and erased from RAM as needed. RAM can be found various places in a computer system. RAM's job is to hold programs and data while they are in use. Now a days we also found NVRAM. The full form of NVRAM is non-volatile random access memory. Non-volatile chips can hold the data, even the main power is turned off.
What memory is very fast memory circuitry located near the CPU that is used to speed up processing?
RAM

Write a short note on computer memory?
1 what is computer memory 2 explain information system. discuss various information systems available in any organization.
What is the longest memory capacity of a computer?
you can have as much as you like. you would just have to get a bigger hard drive, memory stick, external hard drive or server etc.
How many nuMBer of address lines required for 1 MB memory?
Firstly we need to convert Mb's into bits
i.e 1Mb=1024x1024
= 210x210
=220
That means there are 220 memory locations and we will need 20 address lines.
