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 is access time in case of computer memory?
Access time in case of computer memory is the time a program or device takes to locate single piece of information and then make it available to computer for processing.
The first instruction in the ROM BIOS startup program is always assigned to?
Memory address FFFF0h is the memory address always assigned to the first instruction in the ROM BIOS
A physical hard drive that has 2 or more drive letters?
It probably has a partition, which is a way of separating a physical drive into 2 or more logical drives. This is useful is you want to install 2 operating systems, or if you want your operating system on one drive and your data on the other.
How big is 4096 ram on computers?
Well, that depends. You left out whether that is kilobytes, megabytes, or whatever. If you mean megabytes, then that is four gigabytes, or four "gigs" if you will. Note, however, that unless you are running a 64bit version of windows, you will only be able to use 3GB of that.
Does the speed and or quality of your ram affect how much you can overclock a computers processor?
Speed and quality (brand).
PS: memory parameters are not directly connected to overclocking capabilities of CPU. Usually CPU itself is the major factor. Meaning that even if you have the best memory on the market but your CPU is not capable of overclocking you do get good results. And opposite if you have average quality memory but good CPU you can get very good results. There is one exception. When you overclock both CPU and memory both should be with a right speed and good brand.
Does a magnet affect the computer's memory?
No, computer memory is controlled by electricity flowing through the ram modules.
However it can effect a computer's Hard Drive which is where you store your data, the data is stored on Hard Drives by magnetic arms on the platters within.
It is probably a good idea to avoid having magnets near your computer regardless just to be on the safe side.
A shape memory alloy (SMA, smart metal, memory alloy, muscle wire, smart alloy) is an alloy that "remembers" its original, cold, forged shape, and which returns to that shape after being deformed by applying heat. This material is a lightweight, solid state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems. Shape memory alloys have applications in industries including medical and aerospace.
How much memory does the average person use on a laptop?
There's no real way to measure that scientifically. When more RAM is present on a system, the same applications will use more to cache data and provide quicker response times. RAM usage is also a transient thing; the same application may use different amounts of RAM when being used, when running in the background, or when minimized.
How much faster is DDR3 memory than DDR2?
It is not very noticeable if you upgrade your memory on your computer.
What is the difference between DRAM and SRAM?
Short for static random access memory, and pronounced ess-ram. SRAM is a type of memory that is faster and more reliable than the more common DRAM (dynamic RAM). The term static is derived from the fact that it doesn't need to be refreshed like dynamic RAM. To store 1 bit of information about 6 transistors are used and it does not required refreshing. Because Six transistors are used to store 1 bit of information, it is more costlier than DRAM in terms of cost per bit, where only 1 transistor and 1 capacitor is used to store 1 bit of information.
DRAM stands for dynamic random access memory, a type of memory used in most personal computers. In DRAM to store 1 bit of information 1 transistor and 1 capacitor is used. The information is stored in the capacitor in form of charge, so it required refreshing to retain the charge or data in the capacitor.
SRAM is Static RAM and DRAM is Dynamic RAM. DRAM is slower than SRAM and needs to be refreshed where SRAM does not and is used for cache.
(Static RAM) SRAM is similar to DRAM but does not constantly refresh. SRAM is faster and more expensive than DRAM and is generally used for speed-critical areas of the computer such as cache memory.
(Dynamic Random Access Memory) DRAM is the most common type of memory and is "dynamic" because in order for the memory chip to retain data, it must be refreshed constantly (every few milliseconds). If the cell is not refreshed, the data is lost. DRAM temporarily stores data in a cell composed of a capacitor and a transistor. Each cell contains a specified number of bits. These cells are accessed by row addresses and column addresses.
How do you get the type of motherboard without opening the CPU?
if that's the case then you need a tool to identity the motherboard for you.
a freeware tool called cpu-z will do the job, download it from: http://www.cpuid.com/cpuz.php
download and install, then run and navigate to the main-board tab
there you will find the information you seek.
You just partition the Hard drive not the RAM.
Will all types of RAM fit any type of computer Why or why not?
No, All types of RAM will not fit in any computer. certain RAM fits in Certain Computers. I do not know why they do this but i do know that a while back they had RAM sticks with a notch direcly in the middle and they could be put in backwords witch would couse it to smoke and not work properly. now they moved the notch down the stick a little so as what they say it can only fit "one way" but, i have accully managed to put one backwords and smoke like crazy but that was because the slot was cracked.
Why should RAM be referred to as RWM?
RWM is not a computer term, RAM is Random Access Memory and is referred to as
RAM.
What are the Three System Memory Theory?
There are three types of memory storage systems: sensory memory, short-term memory, and long-term memory.
Computing memory that retains data in the absence of a power supply i.e. it is non-volatile memory. A computer chip with a read-only memory that retains its data when the power is turned off and that can be electronically erased and reprogrammed without being removed from the circuit board, often used in fax machines. Flash memory stores computer data in a solid state format (vs. magnetic). Answer: Flash memory is a form of EAPROM (Electrically Alterable Programmable Read-Only Memory).Each bit of data in a flash memory device is stored in a transistor called a floating gate. The floating gate can only be accessed though another transistor, the control gate.The process the control gate uses to access the floating gate is a field emission phenomenon known as Fowler-Nordheim tunneling. Tunneling allows voltage to flow from the control gate to the floating gate through the dielectric layer of oxide which separates them.
What are the Differences between program invisible registers and program visible registers?
The programming model of the 8086 through the Pentium II’s considered to be program visible because its registers are used during application programming and are specified by the instructions. Other registers, detailed later in this chapter, are considered to be program invisible because they are not addressable directly during applications programming, but may be used indirectly during system programming. Only the 80286 and above contain the program-invisible registers used to control and operate the protected memory system.
How do you find processor usage in ubuntu?
Click on the System menu, go to Administration and then choose System Monitor. Once is open choose the Resources tab, it will show processor usage on a graph; or you can choose the Processes tab to see the CPU usage of individual programs.
There is a way, what you do is either:
1. Think where you're memory stick last was.
2. Retrace your steps
3. Ask who was in that room about it.
Or, the technical way:
1. If you are using a Mac - you're screwed.
2. If you are using a PC you might not be screwed. It's all down to luck.
3. Go to recent documents.
4. Click on it (if it's there)
5. If the file says 'Does Not Exist' you are screwed.
6. If by a 2000-1 chance it works - you're a lucky piece of...
Thanks 4 listening.
What is the maximum amount of RAM supported by an MSI MS-7082 motherboard?
The MSI MS-7082 supports a maximum of 2 GB of RAM, using DDR400 modules in 2 slots (1 GB per slot).
