Understanding Memory (RAM), Hard Drives, and the Difference Between Them. When I was a kid our family computer started complaining about . In an attempt to remedy the problem, we deleted as much unused stuff as we could from the hard drive, but it never seemed to help. We had committed one of the most common computing errors: confusing RAM with hard drive space. Bits and bytes. The confusion is so common, I think, because the two share the same basic terminology: bits, bytes, kilobytes, megabytes, and gigabytes. So let's get those out of the way first.
A bit is the smallest unit of information, like a light that can be described only as . Eight bits- -the number of bits a single character (that is, a letter, numeral, or symbol) is usually represented by- -is called a byte. Since we often deal with information that is many, many bytes in size- -music or movie files, for example- -we use shorthand prefixes like kilo- , mega- , and giga- , for thousands, millions, and billions of bytes, respectively.
A kilobyte (k. B) is 1,0. MB) is 1,0. 48,5.
I won't go into any more technical detail, but if it interests you, Wikipedia is a good resource. Both your computer's hard drive and its memory store information, and the capacity of both is measured in bits, bytes, kilobytes, and so on, but the two store different kinds of information in different ways, which I describe in the next sections.
For starters I'm trying to understand whats the difference between flash memory and. Random access is the ability to access data at random. DRAM - dynamic random access memory; VRAM - video random access memory; SRAM - static random access memory. Accessing Stored Data . A serial (or sequential) access storage device is one that. The difference between the various types of things we might call 'memory. What’s the difference between memory and hard. RAM stands for Random Access Memory. For the average consumer, computer memory is often confused with storage drives, the hardware that is used to store files and install software. What is the maximum cable length supported for an RS-232 serial cable? Sequential access compared to random access.
RAM: Random Access Memory. In desktop computers, RAM takes the form of long, narrow modules, sometimes called . RAM for laptop computers is basically the same, but considerably smaller (and consequently more expensive).
Plan and deploy 64-bit editions of Office 2013. Differences between the 32-bit and. Random Access Memory Functions; Home; Blog. The inverse of RAM is serial access memory. Understanding Memory (RAM), Hard Drives, and the Difference Between. What are the differences between serial access memory.
Random access memory is used to store temporary but. This is unlike serial access memory. The are two major differences between RAM (random access memory). Serial Access (also known as. Direct Access (also known as 'random access). Know the difference between 'Serial' and 'Direct' data access. RAM: Stands for random access memory; refers to memory that the microprocessor can read from and write to. When you create something in memory, it’s done in RAM. The major difference between the FM25V10. What are the differences between NAND and NOR flash? What is the difference between Flash memory and. Two Flash Technologies Compared: NOR vs. NOR flash is basically a random access memory.
Most new computers are sold with 1 or 2 gigabytes (GB) of RAM. Older ones may have 2. MB, and top- of- the- lines might have 2.
GB, 3. GB, or more. RAM's purpose in a computer is temporary storage for information that the computer is using right now. If you're listening to music, parts of the song file will be present in RAM, as well as the software that's being used to play it. Fs Global Real Weather V1 727 Food.
What’s the Diff: RAM vs Storage. The difference between Memory and Storage. RAM stands for Random Access Memory. Sequential access memory In computing, sequential access memory. This is in contrast to random access memory (RAM) where data can be accessed in any order.
If you're reading an email, the text of the email is in RAM, and likewise the software needed to read it. All programs, including Windows itself, your web browser, video players, instant messaging programs, and so on, use memory while they're running (even if they're not visible on the screen and minimized or hidden). Unfortunately your computer's memory is finite. If a program complains of . The computer can compensate, to a degree, by using . By its very nature, as soon as you turn off the computer, everything in memory is instantly gone.
Without electricity running through them, RAM modules are blank slates and inert as rocks. That's just fine, though. For storing information we want to keep around, we have hard drives. The hard drive. The proper term here, technical types will tell you, is hard disk drive. An apt metaphor is a record player: The disk refers to one or more circular platters that are like vinyl records but permanently mounted on a spindle. Instead of vinyl, however, they're made out of metal or glass and are coated with a magnetic material.
The rest of the device is the drive, which is like the record player itself: It has a motor that turns the disks on the spindle and read- write heads for each platter, which are like the record player's needle, except that they use magnetism to both access- -. The drive also contains electronics that control these parts and let it talk to the rest of the computer.
Most hard drives in desktop computers are similar in size and shape to a small paperback book, while laptop hard drives are a bit smaller than a deck of cards, and even smaller hard drives are used in some i. Pods and similar devices. The platters in a hard drive spin very fast- -7,2. RPMs is typical- -and the read- write heads move incredibly fast as well (these are the sounds you hear from within your computer when it's working hard), but compared to RAM accessing a hard drive is very slow- -milliseconds compared to RAM's nanoseconds (that is, a million times slower). But, per gigabyte, hard drives are much cheaper to manufacture than RAM, and unlike RAM, data stored on a hard drive will remain intact for many years, even in the absence of electricity, which is why we use them for long- term storage.
Though they work differently inside, for the purposes of the rest of this article they're functionally equivalent to their platter- spinning cousins.)By long- term storage I mean stuff you keep: The documents you create in Microsoft Word, your web browser bookmarks and history, photos, music and videos you save, and so on. These things- -unless you keep them on removable media like a CD or USB flash drive- -are all stored on your hard drive. Windows, as well as programs you've installed, along with their settings, are also stored on your hard drive- -it isn't until you run them that they're loaded into RAM.
New computers typically come with hard drives that hold anywhere from 3. GB to 2. 50. GB of data, but this is constantly increasing- -hard drives up to 1,0. GB (one terabyte, or TB, i. Partitions are sometimes, confusingly, also called drives. You might, for example, have a . A partition can be split up into different folders, also called directories.
You probably save your documents in the . The music you've copied from CDs, the movies you've downloaded, the documents you've saved, the programs you've installed- -all have contributed to your hard drive being filled, and once it's full you can't put anything else on it.
The only solutions are to delete some large files- -perhaps copying them to a CD first- -or to buy a larger hard drive. Virtual memory. Your computer's memory and its hard drive are two distinct things- -I hope I've illustrated that successfully. But there is one place where they overlap: Virtual memory. Relatively speaking, RAM is expensive and hard drive space is cheap, and we must live with a lot of latter and relatively little of the former. Long ago, however, computer scientists figured out how to use space on the hard drive as though it were extra memory; they called it . Remember that accessing data on your hard drive is a million times slower than accessing data in RAM.
So if the computer is performing a complex operation, or running many programs at once, or manipulating a large file, and runs out of . This is why, when your computer is working hard, you may hear a lot of clicking and whirring sounds from within- -that's the computer rapidly reading and writing data to and from the hard drive. The good news is that because of virtual memory you don't see . The bad news is that the more your computer has to use virtual memory, the slower it will operate. Finally, you only have as much . That means if your hard drive is almost full, programs may not have as much memory as they need, and things will slow down and you may even get errors.
For this reason it's best not to fill your hard drive completely- -a couple gigabytes of elbow room will help keep things running smoothly.
