What is the difference between ram and the ias?
RAM means Random Access Memory. It's a plugin in to the motherboard for the process to use temporary memory.
IAS means Instant access store, It is on the processor chip itself.
How do you know if you have 128MB of RAM memory on your computer?
You click on the start menu, right click on my computer, and click properties. That should give you the information you need to know.
hi you can play all games on very low details or you cant play.its very slow
Why does fast access RAM improve overall performance of a computer system?
The term 'random access' is used because this kind of memory cn be accessed directly (in any order) if a cell's address is given. Only data stored in RAM can be manipulated,thereforeevery program that needs to be executed must be place in the main memory. The amount of main memory is crucial because it determines how many programs can be executed at the same time. The larger the amount of RAM the better the computer response.
What has more memory- 0.99 gb of ram or 512 MB ram?
Many people mistake storage space for memory.
Storage space is usually on a hard drive and can be very large. It is measured in terabytes and gigabytes. 1000 gigabytes equals 1 terabyte.
Memory is use by a computer to run programs and the operating system for the computer itself. This type of memory is usually called RAM or Random Access Memory. They are usually measured in gigabytes and megabytes. 1000 megabytes equals a gigabyte.
Make sure you are comparing the correct type of "memory." Is it for storage or for running the computer?
To take your question at face value, 0.99 gigabytes is much larger than 512 megabytes. 0.99 gb = 990000 mb, so 512 mb would be very small.
How is binary linked to computer memory?
Computer Memory is made of electrical circuits which can either be "on" or "off". Binary is a counting system that uses just "1" and "0". Thus one can map "0" to "off" and "1" to "on" and directly store Binary representations in computer memory circuits.

Physical device are used to construct physical memory?
Physical devices are used for storing physical devices
It basically blocks access to local servers from local pc's using the public address. Doesnt block access to the servers using the lan address though.
Say your public address is 1.1.1.2, and you have a lan of 192.168.1.0/24.
Someone on your lan wants to get to a ftp server at 192.168.1.254 and you have port 21 opened to that ip in your firewall.
With nat redirection enabled, they cannot get to the ftp server from ftp://1.1.1.2, they have to go to ftp://192.168.1.254. From outside you lan they can go to ftp://1.1.1.2.
What is main memory in computer architecture?
main memory is RAM.The words Memory,Buffer,Cache are all refers Ram. Which is Nearly 11,000 times faster than secondary memory (Hard Disk) in Random Access.
Can permanently deleted file be opened if PC is hacked?
No. In order to read data that is deleted, the harddrive would have to be removed and special software would be used to retreive it. If you want to check it out, look on the internet for Forsenic Software or undelete software.
Think about what you are asking. If you backup 100 files then you have to reload 100 files, unless you use some faster hardware to do one or the other they will take the same amount of time...there is no answer. But there are different backups depending on how much you want to backup..you can backup your favorites, emails, and documents all at once with backup on the accessories>system tools. Or you can back up your whole hard drive under the same place.
yes they can they are most common with the r4s so get a different one insted of an r4
What are some of the causes of ACoil Freeze up?
Too little air flow caused by dirty filters, a dirty evaporator coil, a dirty blower or one that is set on too slow a speed or a loose fan belt if you have one are the most common. A mismatched condenser and evaporator, air somehow bypassing the evapoartor coil, low refrigerant charge due to a refrigerant leak. Running the house temp down too low, closed or blocked return grilles and/or supply registers, long piping runs with out sufficiently increasing the pipe size, and improperly sized ductwork are some of the tougher ones to diagnose.
What is write-through in memory caches?
When a datum is written to the cache, it must at some point be written to the backing store as well. The timing of this write is controlled by what is known as the write policy. In a write-through cache, every write to the cache causes a write to the backing store. Alternatively, in a write-back cache, writes are not immediately mirrored to the store. Instead, the cache tracks which of its locations have been written over (these locations are marked dirty). The data in these locations is written back to the backing store when those data are evicted from the cache. For this reason, a miss in a write-back cache will often require two memory accesses to service: one to retrieve the needed datum, and one to write replaced data from the cache to the store.
The preceding information was obtained from the related link at the left.
- Write Back - Data is written first to the cache, then to the logical drive for better performance. The Promise VTrak has a cache backup battery to protect data in the cache from a sudden power failure.
- Write Thru - Also written as "Write Through". Data is written to the cache and the logical drive at the same time for safer operation. No battery backup is needed since data is written to the drives immediately.
Which measure of memory access time is fastest?
There are many measures of memory access. They vary in speed the fastest being magnetic tapes. That may not be a popular choice in this technological age. The next fastest would be magnetic disks, followed by Semiconductor memories and then compact disks.
Where the constantly needed data is stored?
Constantly needed data is stored in RAM, and depending on the system and the CPU used, it may be stored in cache memory. Cache memory is a special, high-speed type of RAM. It is more expensive and uses more current than DRAM, but it is used where speed is critical. Cache memory is generally inside of the CPU these days.
What is the best RAM for gaming?
RAM memory is a very important factor for how well games run, and most gamers prefer having as much RAM as possible. A good amount of RAM would be anything around 4GB or more.
The ram already in it is a micron 4gb 2rx8 PC3L-12800s-11-11-FP

How much memory does Windows 7 x64 takes on hdd without any side programs?
windows 7 (clean install) takes up 40-50 GB hdd space and around 400-700 MB RAM (idle)
What is beter to speed up a p4 computer a DDR or a SDR?
If the motherboard supports both DDR and SDR RAM, it is almost always a better idea to go with DDR RAM
Differences between analog and digital?
A great question!
We hear much about digital and analog signals and most people know nothing about the difference. Let's try to give some simple basics.
A digital piece of electronics is either on, or it is off, Black or white with no gray in between. Early electrical devices used 5 volts circuitry. If the five volts was there, we had a digital "on" condition. If the 5 volts was not there, we had a digital "off" condition. We could use this in many ways. One way was to call the "on" condition a mathematical "1" and the ansence if the voltage a "0". That means we could make electrical devices count to one! BIG DEAL? well, yes it was because that is how every computer out there works, as well as how the internet transfers all this cool stuff!
Analog is everything in between the "0" and the "1" of digital electronics. This an probably the most interesting area for most engineers that really know electronics. You may be able to save audio information in digital form, but your ear sure wants to hear it in analog. The ability to vary voltages between the full on and off of the divice requires more currents and more design abilities. All actual transmission of every radio or television signal is done through and analog transmitter. When you hear about the end of analog television and the new digital transmission, they are actually discussing the input to the analog transmitter.
The ability to decode digital transmissions on this analog signal allows us to use much more of the transmission band for the given device. A television signal that could only put out maybe 7 signals in analog now can carry many signals. That television station you are watching could also be sending a great deal of other information out! Even in analog we could send a dozen different things out "behind" that signal you could hear and see. "Muzak" (the elevator music) goes out "behind" these tv or radio signals (called sub carriers). Digital encoding of this information allows for many many times the sub carriers on a given station.
