The cheapest form of read/write memory in wide use today is the hard disk. Hard disks provide large quantities of inexpensive, permanent storage. You can buy hard disk space for pennies per megabyte, but it can take a good bit of time (approaching a second) to read a megabyte off a hard disk.

This is where things can get slightly confusing. RAM has the name randomaccessbecause (in theory) it's just as quick for the computer toread or write information from any one part of a RAM memory chip as from anyother. (Incidentally, that applies just as much to most ROM chips, whichyou could say are examples of nonvolatile, RAM chips!) Hard drives...
RAM comes in two main varieties called DRAM (dynamic RAM) andSRAM (static RAM). DRAM is the less expensive of the two and has a higher density(packs more data into a smaller space) than SRAM, so it's used formost of the internal memory you find in PCs, games consoles, and so on.SRAM is faster and uses less power than DRAM and, given its greatercost...
Like RAM, ROM also comes in different varieties—and, just to confuse matters, not all of it is strictlyreadonly. The flash-memory you find in USB memory sticks anddigital camera memory cards is actually a kind of ROM that retainsinformation almost indefinitely, even when the power is off (much like conventional ROM) butcan still be reprogrammed rel...
Oct 1, 2024 · A computer hard disk drive (HDD) is a non-volatile data storage device. Non-volatile refers to storage devices that maintain stored data when turned off. All computers need a storage device, and HDDs are just one example of a type of storage device.
RAM is WAY faster. Like… a ton faster… like… flash Gordon fast. To make this clear, here are some tech numbers. The average modern hard drive reads at between 50-70MB/s. The average (actually order DDR2) RAM reads at over 5,000MB/s, and can go up to 12,800MB/s.
Dec 1, 2018 · Hard drive vs memory: both are types of internal storage spaces in a computer, but each serves a different purpose. In this article, we’ll highlight the different role that hard drives and memory play in a computer.
Jun 8, 2024 · The microprocessor in your computer is the bit that does all the "thinking" and calculating—but it's the hard drive that gives your computer its prodigious memory and lets you store digital photos, music files, and text documents. How does it work? Let's take a closer look! Photo: A 30GB (gigabyte) hard drive from an old laptop computer.

Disks, HDDs and SSDs are devices used to store data long term. Disks retain their contents without power. Memory always refers to RAM. Disk space refers to disk space. RAM stands for Random Access Memory. RAM is a collection of electronic circuitry where your computer’s programs and data are stored when it is running. Random Access Memory sticks.
