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.

They are both needed for your computer to work. You make the decision.
Fiber Distributed Data Interface (FDDI) NICs are commonly used to connect host systems or file servers to FDDI network equipment using one connectin (single attachment) and to attach the network equipment to the FDDI cabling through two attachments (dual attachment).
FDDI is defined by the ANSI X3T9.5 standards committee and provides an access method to enable high-capacity data throughput on busy networks. It has a data throughput rate of 100Mbps, and is simliar to the token ring access method because it uses token passing for network communication.
Remove the RAM stick from the motherboard and then desolder it from the PCB. But after dont put the RAM stick back in, unless you wanna break your computer.
What and where is the fire wall and plugs on the computer located?
The firewall on a computer is not, generally, a physical thing at all, but is a software program that watches everything happening on the network and stops network activity that it believes could be harmful.
The firewall, as it watches what is happening on the network, could be said to be connected to the network plug, which is a small, square plug, generally on the back of the computer. It looks like an oversized phone jack. Do not plug a phone jack into a network connector; it will destroy your network hardware.
DDR3, you can check with the manufacturer if you're not sure.
How do you know what type of motherboard yor're using?
Several methods can get you this information. You could look at your computers POST bootup screen which will sometimes give you this information. You could look for a model number embedded on the motherboards face itself, and you could also look in your computer manuals for this information. Alot of times if the computer is a prebuilt like a Gateway, Dell, etc. they do not readily give you this information. You can download utilities off the internet that will read hardware information from your motherboard and display it.
Can you install two different ram clock rates like a ddr3 1600 and a ddr3 1333?
yes, you can. but both will run on the lowest component speed.. so your ddr3 1600 module will only run at 1333.
What is the purpose of ddr2 pc2 6400?
The purpose of the ddr2 pc2 6400 is to provide more memory to users. Keep in mind that before purchase, it does not work with every type of computer, so you need to double check.
That is simple as example USB flash memory, pen drives, memory cards.
Can RAM be totally replaced by cache memory?
A resounding "sort of!" You could, but it would defeat the point of having a cache to begin with.
Physically, the cache(s) of a computer is (are) located closer to the CPU than the RAM - so even if you replaced the RAM with a higher-speed memory, the part that was further away from the CPU would take longer to access than the part that was closer (although the difference would be very small). Cache is also much more expensive than RAM to create, although that doesn't mean it's impossible, and the speed of access is still limited by the speed of the FSB (Front Side Bus). Although cache may have a faster access time than RAM, it is not efficient (cost-wise, at least!) to simply cache everything because you don't necessarily need to use everything right away all the time - cache exists to give you faster access to time-expensive data that you use often. It could get to the point where even your cache would need cache!
Can you put as many memory ram cards in your PC as you want?
Sorry...you can only put in as many as the motherboard will accept...ie: slots 1&2, slots 3&4 (that is usually all that the PC hold. Now, in the older PCs there was a 'piggyback' card that could accept another two mem cards then it would go into the slot..but, now I do not think that is acceptable.
Size of computer memory refers to RAM or hard disk?
RAM (Random Access "Memory") stores information temporarily while the power is on. Hard Disk "Space" stores information permanently regardless of whether the power is on or off.
Computer specifications usually specify RAM as system "memory" (like 2GB DDR2 MEMORY) and refer to Hard Disk storage as "Hard Drive(s)", system "storage", or "Disk Space" (like 320GB HARD DRIVE).
Think of the Hard Drive as a storage shed and the RAM as the playground. The computer gets the programs/data from the hard drive and pulls them out temporarily into the playground for you to use, then stores them back in the shed when you are done.
What if Cache size is equal to main memory size?
If we took size of cache as large as size of main memory then the main purpose of cache(take less time) would come to end, as larger the cache slower would be it's processing speed.

There are 64GB hard drives, in fact, that is a fairly average size hard drive. There is no such thing as 64GB RAM. The largest RAM available is 4 GB and that is the most any computer at this time can hold. You can use some of your hard drive as memory, that is called Virtual Memory and the motherboad does it automatically but you can change it in the software of Windows. I would suggest you review the documentation on the Internet on the motherboard or the system that you have, it will give you the correct amount of Virtual Memory to use. 64GB is not realistic and your system will be unstable.
:::This is the asker- you are missing my point: I am talking theoretically about what would the difference be between a SOLID STATE (not spinning) hard drive and flash memory of the same size- and since swap space (Virtual Memory) is simply hard disk space allotted to write unused RAM memory items temporalily, if you have a solid state hard drive with superfast read/write (like RAM, since it's basically the same thing), whether you could have virtually unlimited RAM just by increasing your swap space when you have a solid state hard drive? I was not asking about my computer at all... Also I think you can have more than 4 gb of ram, if you install it yourself There are many MAJOR differences between solid state drives and RAM. The main differences are: 1. Solid State drives are non-volatile so when you turn the computer off whatever is stored on it is still there. RAM requires power to retain information stored on it. 2. The attainable speed on the two are different due to architecture and as of now RAM is significantly faster. As far as having 64 GB of ram, the barrier at the moment is 16 GB max on a 64 bit processor (for desktop computers, mainframes and servers are different due to architecture). If you did have 64 GB of RAM, you would be able to make faster speed exchanges than 64 GB of virtual memory due to bus speeds and relative distance from the CPU. If you actually needed to utilize 64 GB of the fastest memory possible then you would want RAM. Honestly though if you need that much then you are probably doing extreme theoretical work and should look into distributed computing or mainframes because Im sure there is are multiple barriers for the CPU...
Memory modules will have a small notch in the bottom edge that ensures it can only be inserted into a slot one way.
What are the levels of Computer data storage?
In ascending order (least to greatest), it goes
Bit, byte, kilobit, kilobyte, megabit, megabyte, gigabit, gigabyte, terabit, terabyte, petabyte. I think petabit MAY be right between terabyte and petabyte, but it is underlined when I type in to my computer, so I am not sure.
What type of volatile memory is usually used only for temporary storage while running a program?
RAM--Random Access Memory.
Why temporary memory is required for computer even though permanent is available?
Temporary memory is used to store program and applications that are being used at the time and allows for computing to be much faster. After the program closes the memory is no longer needed. there are two types RAM and Virtual Memory. RAM is a separate card and stands for Random Access Memory. Virtual Memory is space reserved on the Hard drive for the same purpose. By far the most efficient type is RAM as it is much faster than Virtual Memory and doesn't take Hard drive space al though for a modern computer both are needed for efficient performance.
How are facts retrieved from long-term memory?
A person has to process their long term memory to remember facts that have been saved in their brain. Some people can store a lot of facts in their long term memory and discuss it any time.
Is it possible to run a computer without primary memory?
Yes, that is how computers used to run, it is called D.O.S.. but it will not give you any fancy video, that's for sure
