What is a term that refers to the permanent storage of computer programs files and data?
read only memory
What does 512 MB of ram equal?
To give a basic overview of RAM and ROM: Read-only-memory refers to memory that cannot be changed. You have it in your computer under the form of a BIOS ROM chip. Files and programs are stored in non-volatile memory (such as hard drives) then transferred to Random-Access-Memory (RAM, usually called "memory" by the average person) to work with.
RAM (Random-Access-Memory) is what the computer works with. Most computers now days come out with at least 2GB of RAM (512MB is half a gigabyte).
RAM is one of the major deciding factors in how fast your computer runs. It can be upgraded but should only be upgraded by someone knowledgeable in the subject and shouldn't be attempted by a non-professional, especially while under warranty.
One of the reasons to get a higher amount of RAM is to run games. All games should have minimum specifications, which is the lowest amount of hard drive space, RAM, graphics et cetera to run the game. For example, The Sims 3 has a minimum specification of 2GB of RAM.
Programs can take up different amount of RAM. On average, on my laptop iTunes will take up around 500MB of RAM (though I have a large library and use the album art look), Google Chrome (my web browser) uses roughly 90MB with a few tabs open and Word 2010 uses roughly 55MB. However, these are only rough estimates and shouldn't be used as your only sources.
How do you overclock your motherboard?
There are several methods that people have used to overclock their processors:
1. Crystal Oscillator - A crystal oscillator is a small electronic component that generates a steady clock signal, expressed in MHz or KHz (ex. 27.1432 MHz) or. By replacing the clock signal with one that generates a higher clock (ex. 29.7265 MHz), you would make your processor also run faster. Although still possible, this method is more awkward on modern motherboards, because of the high internal multipliers and numerous buses running at lower speeds (curse you, PCI!). This method is still useful on many game consoles and portable devices, however.
2. Adjusting Front Side Bus speed (jumpers) - The processor always runs at a multiple of the Front Side Bus (FSB) speed. By increasing the FSB speed, the internal speed of the processor would also be increased. For instance, if the FSB speed is at 66 Mhz, and the multiplier is 3, the processor runs at 200 MHz. If the FSB is increased to 100 MHz, the processor will run at 300 MHz. This method has been largely replaced by doing it in the BIOS, since after the Socket 7 era.
3. Adjusting CPU multipliers (jumpers) - Adjuisting the multipliers for the CPU was a slightly easier and more reliable way to overclock, since it did not stress any other components, such as PCI or ISA. If the FSB was at 66 MHz, and the multiplier was at 3, the processor would run at 200 MHz. If the multiplier was changed to 4.5, the processor would run at 300 MHz. Intel locked the multipliers on all their processors after the Socket 7 era.
4. Adjusting Front Side Bus speed (BIOS) - Starting with the Pentium II era, Intel processor were multiplier-locked. The only method to increase the processor speed was to increase the FSB speed. This could be done in the BIOS of many non-OEM (ASUS, Abit, Tyan, DFI, and not Gateway, HP, Dell, or Acer) motherboards. Although it stressed the other buses slightly doing so, the higher multipliers in processors made even a small increase in FSB speed a large boost in clock speed. This method is still commonly used today.
5. Adjusting CPU multipliers (BIOS) - AMD left their multipliers unlocked for a long period of time. Even when they began locking them, they left them in a way that was easily unlocked again. Jumpers on the motherboard were replaced with settings in the BIOS. This method is not common today, although AMD still has some unlocked CPUs, and even Intel has begun unlocking their high-end enthusiast (Extreme) chips again.
6. Adjusting Front Side Bus (software) - The FSB speed, along with the other buses, is controlled nowadays by a chip known as a PLL. The crystal oscillator still exists, but it primarily serves as a reference clock signal for the PLL. The PLL is more often controlled through the BIOS, but special programs running in Windows are also available. This method is the only overclocking option available for many OEM motherboards (though some may still not work through this method). You will first have to reboot you computer into the BIOS ( usually by pressing the Delete key during start up). go to the Frequency Voltage control menu, find the entry called CPU FSB Clock, and increase it by the smallest amount possible (2MHz is usually a reasonable increment). Don't get impatient and try for a large jump, you'll have only yourself to blame if you fry a very expensive chip. Finally, save the settings and reboot your PC. Be aware that increasing the speed of the front-side bus also increases the speed of your system RAM, which could prove the limiting factor.
There are many ways to overclock, and there are a lot of resources available on the Internet. With that said, it is possible to overclock a device through utilities, possibly through human ingenuity, (for example, the pencil trick for computer motherboards) and much more.
What is the name of the storage location in the computer's memory?
Depending on the architecture of the computer one addressable memory location might be called a word, a character, a parcel, a decimal digit, a byte, etc.
Two advantages that main memory has over magnetic disk storage?
Faster access time(uses data bus directly and not through any controller) and no moving parts
- Improvement in the uniformity of the magnetic filmsurface to increase disk reliability.
- A significant reduction in overall surface defects to help reduce read/write errors.
- Ability to support lower fly heights (described subsequently).Better stiffness to reduce disk dynamics.
- Greater ability to withstand shock and damage
Which memory temporarily holds data and instructions as the CPU processes them?
RAM (Random Access Memory) and SRAM (Static Random Access Memory) are the most commonly used types of memory used to hold instructions. RAM is the familiar chips you see people use to upgrade memory on the machine. SRAM is normally integrated and very expensive but much faster than normal RAM because it communicates directly with the processor.
What is the storage capacity of cache memory?
Cache memory is a type of memory. It does not dictate a specific quantity. The actual amount varies and can best be determined by looking up the specifications for your particular CPU chip.
PC5300 memory, is one of the newest types of memory. Thus being DDR II. The slot in the middle, is slightly different to that of DDR ram. This is the easiest way of telling the two apart.
Hope this helps
be safe
What is memory that loses its contents when the computer's power goes off called?
RAM or Random Access Memory
Is RIMM or DIMM more expensive given that both hold the same amount of memory?
RIMMs are copyrighted so companies have to pay to produce them. also, RIMM is legacy and getting to be much harder to find.
DIMM is open tech and they are now faster than Rambus anyway.
How do you tell which CPU fits what motherboard?
I am going to assume you're being technical and using the term CPU meaning the processor specifically. Usually when you buy a motherboard located somewhere in the specifications it will tell you what "socket" the motherboard supports. Just like how only US electrical plugs will fit into US electrical outlets, it is the same for motherboards. For example, the Asus Intel P965 Motherboard states it supports socket 775 processors. Usually the motherboard will have the processor it supports in the title name, this one being Asus Intel. So by buying that motherboard you would go and buy a processor, that's made by Intel, with a socket 775 fit. Unfortunately technology has its limitations, so if you buy a motherboard and your socket becomes outdated, you will probably have to buy a new motherboard to accommodate the new sockets if you ever want to upgrade the processor. On the plus side, motherboards aren't all that expensive. However, processors ARE expensive, especially if you plan to go over 2 Gigahertz in speed. The Intel Core 2 Extreme Processor E6800 2.93 GHz processor costs $1,049.99, according to Best Buy. So, make sure you plan your computer investments wisely.
What is the typed of memory where information is stored for the shortest period of time?
Short term memory
Short term memory. RAM. Wet mud. Chalk boards. Sidewalks (with spray paint). Walls (with spray paint). Paper. The back of your hand, if you're forgetful. Your fingers and toes. Your teeth (store for a short time what you recently ate). This is a stupid question.
What is the function of the memory controller chip?
The memory controller hub in a PC -- often called the northbridge -- is one of two chips in the core logic chipset on a PC motherboard; the other chip in the set is usually called the southbridge. The northbridge typically handles communications among the CPU, the RAM, the BIOS ROM, the PCI-E (or AGP) video adapter, and the southbridge chip.
How much does 8 GB of RAM cost for a desktop PC?
8 GB of RAM will be approximately $45 - $50 at most places. The price is fairly inexpensive at this time as they are offering even larger RAM in the marketplace.
The cost of RAM will depend on the particular Mac model. Modern Macs use standard SO-DIMM components which will cost around $40 (£30) for 2GB and can be obtained from any reliable supplier. Added memory should match the speed of existing memory. Details of existing memory can be found by selecting About This Mac from the Apple menu (top left corner), then clicking the More Info button to open the System Profiler, and selecting Memory (in the Hardware section) in the left hand pane.
If the computer is turned off will a word document remain stored in the computer memory?
if you save the document before you turn off the computer then it will be saved into the computer memory but if not it will be lost. most computers ask you if you want to save the document before the computer shuts down if that happens all you have to do is click yes you want to save and your done as soon as you name the document.
The prefix for kilo means 1000, also have a meaning when speaking of computer terms. The definition would be a multiple of the unit byte (meaning unit of digital information). Kilobyte is used to mean either 1000 bytes or 1024 bytes. This was used as an originated compromise technical jargon for byte multiples that needed to express by the powers of 2.
Why computers are necessary in this world?
Having a computer is not necessary, but a matter of opinion, although having a computer has many benefits.
Some of the benefits of having a computer:
Having a computer usually means that you are able to search online for questions, things to buy, and information on a wide variety of topics. Having access to these things can help you a lot, with research and other needs that you might use it for.
Having a computer will allow you to 'connect' to the rest of the world through social networking sites, which is ideal for you if you have friends overseas or people who you would like to keep in touch with that you don't see very often.
Having a computer means that you will access to your own email account. When signing up for most things these days, you constantly need an email address, whether it is to join a website, receive newsletter updates, or need to fill in forms for something. Having an email account also means that you will be able to email work, friends, and family whenever you need to.
Having a computer also means that you can do assignments, documents for work, or just write stories on a word or other application document. Having your own computer will mean that things that you can do your office work from home, which can be very convenient, especially for mums or people who are very busy.
These are just some of the benefits of having a computer, but this isn't necessary, just up to you!
Why add more RAM to my computer?
What is virtual memory? We know that computer stores all the data needed for processing in the RAM. But the RAM has a limit. So when your RAM is full, the computer automatically starts writing information on the hard disk. This utilization of hard disk space in place of real memory is called virtual memory. But, by virtual memory, the computer becomes slow as it takes much longer time to retrieve data from Harddisk. So by adding more RAM you get away from the condition where your computer has to go for Virtual Memory and the speed of the computer is maintained.
What is the difference between ram ROM cmos cache and virtual memory?
Short answer is difficult, but we need one. Your computer contains all kinds of virtual memory.. on the RAM chips primarily. Maxed-out older computers resort to using space on the disk drive, which is relatively slow. A cache is a saved memory of what you have recently been doing, and is used since it is very fast. It duplicates a finite amount of what is in virtual memory.
What are two kind of memory in a computer?
That depends on what you mean by "Memory". If you are talking generally then there is Hard Disk Memory, Flash Memory, and RAM (Random Access Memory), usually when referring to memory in a computer though people are talking about the RAM. There are 4 types of RAM (That I know of) which are SD RAM, DDR, DDR2 and DDR3.
Because you can change the settings to the CMOS setup by pressing a key or combination of keys during the boot process, whereas you have to open your PC to change jumpers or switches.
What type of RAM do most laptops use?
The question is broad so the answer is also they use sodimm,which are smaller modules in a 200 or 204 pin attachment....the newest would use DDR3,older DDR2 or DDR.The best way to check what you have is to find out the specs of your motherboard,with that information you could buy the right type and amount the motherboard could handle.....side note if your running Xp it can only handle 4 gig's of ram if your board supports that amount
What is the main memory of the computer?
# Main memory is the short term memory of a computer. It retains data only for the period that a program is running, and that's it.
