Computer Memory

DDR3 is the generation of ram; it is presently the newest. 1333 is the MHz rating (speed) 1333 is the basic speed rating for the DDR3 generation

RAM is another name for memory in a computer.

One task that can be performed by RAM (random-access memory) is to store data that is input into an application and holds it there only while the application is running. RAM also allows a user to do more things at once, depending on the amount of RAM the computer has. In other words, the more RAM your computer has, the more windows you can have open to work in without slowing down your computer.

Physical memory is a term used to describe the amount of memory [RAM] installed in your computer.

Yes! 2GB is a good Amount of RAM depending on your Operating System, In Windows Vista Or 7 Minimum Is 1GB and Recommended is at least 2GB, but on XP you might only need 1GB. But this depends on what programs you run and if you are a do heavy multitasking or not. Remember, The More The Better! Gaming should be around 4GB to 8GB depending on the games you play running windows 7 or higher.

Hope this Helps! :)

Virtual memory is a special file on the harddisk that the operating system can swap pages of physical RAM back and forth with to allow more programs than fit in physical RAM to run on the machine at the same time. For example on the computer I am writing this on right now the installed physical RAM is only 1GB, but the virtual memory file is about 50GB. Thats a lot more resident programs and data than the machine could support without the virtual memory!

There are 5120 MB in 5 GB. Refer to below : 1 bit = the value of 0 or 1 8 bits = 1 byte 1024 bytes = 1 kilobyte 1024 kilobytes = 1 megabyte 1024 megabytes = 1 gigabyte 1024 gigabytes = 1 terabyte 1024 terabytes = 1 petabyte So 1024 MB = 1 GB so i did 1024 * 5 and got 5150 MB in 5 GB.

In other words, MAR holds the memory location of data that needs to be accessed. When reading from memory, data addressed by MAR is fed into the MDR (memory data register) and then used by the CPU. When writing to memory, the CPU writes data from MDR to the memory location whose address is stored in MAR.

The Memory Address Register is half of a minimal interface between a microprogram and computer storage. The other half is a memory data register.

Far more complex memory interfaces exist, but this is the least that can work.

One million bytes.

Actually, 1,048,576 bytes.

1 kilobyte = 1024 bytes

1 megabyte = 1024 kilobytes

1024 * 1024 = 1,048,576

Slowdowns mainly as the computer swaps memory to hard disk "virtual memory"

If you open too many tabs on a browser, for example, other programs may not be able to open, or you may not be able to use functions of the browser (such as saving things)

If you experience this while web browsing, save your tabs as a bookmark folder, then try other browsers, such as 64-bit Firefox3.7, Chrome6.422, Opera10.54.21868 or Safari4, though usually IE8 is the best, so use IE8 if you are not using it already.

If you have 64-bit windows, run the 64-bit version in C:\Program Files\Internet Explorer because the 32-bit one is on by default

When the Semiconductor technology not in existence there was a usage of magnetic tapes and magnetic drums which were the Sequential access means If you currently at the position of words which is starts from 'A' so if you need to look up the words started from 'Z' then you've to go through all alphabets means b,c,d........y then you'll get your position at 'Z'. It's similar to Audio or Video cassette.....

But the Ram is Random Access means "The ability of a computer to find and go directly to a particular storage location without having to search sequentially from the beginning location"

The human equivalent of random access would be the ability to find a desired address in an address book without having to proceed sequentially through all the addresses.

Your question is a little vague - However... RAM is faster than say, a hard-disk because RAM is made of silicon chips holding thousands of tiny electronic switches which are quicker to access. On a hard-disk - the information has to be found first by reading a 'reference track' which locates the information on the disk - then a read-head has to physically move to that part of the disk.

Yes it is true that memory caching is a method used to store data or programs in SRAM for quick retrieval. The North Bridge is the faster end of the hub that contains the graphics and memory controller.

A memory cell is an individual part of memory, usually just a single bit. A DRAM "cell" is composed of a transistor and a capacitor, with memory refresh used to keep the charged capacitors charged and the drained ones drained until the values change. A SRAM cell is comprised of a transistor latch gate using 4-6 transistors. SRAM memory takes more power but does not need refreshed.

to find the memory from address lines. you just have to make address liness power of 2, as shown below for 12 address lines 212 bits. 212 = 22 * 210 = 4 Kb
that means we can address 4 Kb from 12 address lines.........

Since most cache memory is located on or near the processor (say, inside a slot device for slot-packaged processors), you'll need a new processor entirely. Some older computers allow you to upgrade a cache chip on the motherboard, so you can refer to the computer documentation to find how to upgrade that chip.

a gigabyte equals 1000 megabytes. so 512000/1000=512 gigabytes.

Currently, the largest named unit of data measurement is the heileybyte which is (give or take) 1211288155777568604160000 bytes. The largest reachable amount of data is the petabyte or 1100585369600 bytes. The current file system, NTFS, can only address hard drives up to 25 petabytes. Here is the list of all the data unit measurements:

As you would expect in such an answer: "It Depends!" On a computer system, if one has one weak area (or a "weak link in the chain") then improving that "weak link" will make a huge difference. For instance, one had a PC with an AMD 5000+ X2 processor with only 512 MB of RAM running windows Vista, then the computer performance would greatly be improved with another 1G or even 512MB of RAM. Most systems which you buy at the store are designed to have balanced "links" in the chains. So overall, memory can improve your speed, but may not necessarily.

Note also that different software demands different resources. Video editing uses a lot of memory, VISTA demands more memory than Windows 98.

Also some video cards rely on system memory rather than its own independent memory. If you are using an Intel GMA950, then it will take advantage of more memory.

If you already have a well balanced system with software that does not harness the memory then adding memory to your system will not help much. If your system is unbalanced in the RAM realm, then memory will make a large difference.

For a USB drive (aka Flash Drive), unplug the device.

If you want to be more careful about it, make sure your operating system (or the computer) is not using the device.
The simplest way to ensure this is to shut down the computer.

Another way to do this: wait until the device is not being "read from" or "written to" (close windows that are open that refer to the device) and then try to "eject" the device. Depending on your system, you usually right click (or click-hold) on the icon representing your drive in the task tray. Then you select "unplug" or "eject" and wait until the device disappears from the tray.

Then unplug the device (as above).

Use a rubberized or wooden surface for placing the components on. Never place anything on synthetic materials such as nylon, wool or cotton as it will produce static electricity. Make sure your grounded, do so by touching a metal radiator or metal rod. Products such as anti-static wrist bands can help reduce the risk of damage. Other than that, the risk is very small.

Your good to go!
