What is ram and rom

Random Access Memory (RAM) is a type of computer memory that is used to temporarily store data that the computer is currently using or processing. RAM is volatile memory, which means that the data stored in it is lost when the power is turned off. RAM is typically used to store the operating system, application programs, and data that the computer is currently using. Read Only Memory (ROM) is a type of computer memory that is used to permanently store data that does not need to be modified. ROM is non-volatile memory, which means that the data stored in it is retained even when the power is turned off. ROM is typically used to store the computer’s BIOS (basic input/output system), which contains the instructions for booting the computer, as well as firmware for other hardware devices. Types of Memory Memory is the most essential element of a computing system because without it computer can’t perform simple tasks. Both types of memory (RAM and ROM) are important for the computer, but they serve different purposes. RAM is used to store data that the computer is currently using, while ROM is used to store data that the computer needs to boot and operate. RAM is faster than ROM, as the data stored in it can be accessed and modified in any order, while data stored in ROM can only be read. Computer memory is of two basic types: Classification of Primary Memory Random Access Memory (RAM) • It is also called read-write memory or the main memory or the primary memory. • The program...

RAM stands for Random Access Memory, and if you’ve ever opened a lap- or desktop computer, you’ve seen it. In the image above, you see modern RAM sticks for desktop PCs. They have a sleek casing that functions as a heat spreader. However, unless you’re a high-powered overclocker, this is mostly about looks (and making them easier to install.) Laptops, meanwhile, often have more basic RAM sticks, as space concerns are paramount. Plus, unlike modern PC cases with transparent sides, people rarely see the inside of a laptop. However, you can get laptop RAM (especially for gaming models) with heat spreaders. What RAM Does So now, we know that those sticks in your PC’s motherboard are system RAM, and they function as short-term memory, but what does that all mean in practice? Well, when you carry out actions on your computer, like opening a text document, it requires access to the data contained in that file. When you’re no...

RAM, also known as memory, is one of the most important components in determining your computer’s speed and overall performance. So, whether you’re looking to buy a new computer, or you want to speed up your current PC, it’s crucial to understand what RAM is, and how much memory you actually need. Here’s everything you need to know about what RAM does, and how to find out if you have enough memory you have on your Mac or Windows computer. What Is RAM? Random access memory (RAM) is a hardware component that is used to store temporary data for the programs running on computers, smartphones, gaming consoles, and other devices. Operating systems (like Windows and macOS) need to have a certain amount of memory installed just to boot up. What Does RAM Do? You can think of RAM as your computer’s short-term memory. It provides temporary storage space for data and program codes that your computer is currently using. Your computer uses memory to launch programs, process actions, load features, and more. While your hard drive and RAM are both measured in gigabytes (GB), they do very different things. You can think of your hard drive like your computer’s long-term memory, where all your files and programs are stored when they are not in use. However, the data stored in your RAM will be erased whenever you turn off your computer. (Image Source: Your computer’s RAM is faster than the best long-term storage drives today.

There are many types of RAM, so you may hear it called by other names. It's also known as main memory, internal memory, primary storage, primary memory, memory "stick", and RAM "stick". What Is RAM? Put simply, the purpose of RAM is to provide quick read and write access to a storage device. Your computer uses RAM to load data because it's much quicker than running that same data directly off of a hard drive. Lifewire / Kyle Fewel Think of RAM like an office desk. A desk is used for quick access to important documents, writing tools, and other items that you need right now. Without a desk, you'd keep everything stored in drawers and filing cabinets, meaning it would take much longer to do your everyday tasks since you would have to constantly reach into these storage compartments to get what you need, and then spend additional time putting them away. Similarly, all the data you're actively using on your computer (or smartphone, tablet, etc.) is temporarily stored in RAM. This type of memory, like a desk in the analogy, provides much faster read/write times than using a hard drive. Most hard drives are considerably slower than RAM due to physical limitations like rotation speed. RAM Works With Your Hard Drive (But They're Different Things) RAM is typically referred to simply as "memory" even though other types of memory may exist inside a computer. RAM, which is the focus of this article, has nothing at all to do with the amount of file storage a hard drive has, even though...

Don't worry though, I cover hardware components for a living and have been studying computer science for nearly a decade now, so I'm here to answer the question 'what is RAM?', but also explain what it does and how much you need for your next PC. I'll also help you figure out which kind you need so you make the right choice of the (Image credit: Future / John Loeffler) What is RAM memory? Random Access Memory (RAM) is a type of computer memory that lets the CPU temporarily store program data that it is actively working on or with. It is often referred to as "main memory" because of the critical role it plays in your computer's operations and in the overall performance of a computer. Is 8 GB RAM good for my needs? Is 8GB of RAM good? For general computing use, 8GB of RAM is more than enough for day-to-day work, like productivity apps, web browsing, and video streaming. Given the size of the files you'd need to work on in multimedia projects like video editing or graphic design, or needed while gaming, 8GB is generally considered too little memory capacity for gaming and creative content usage. How much RAM do you need? (Image credit: Future / John Loeffler) How much RAM do you need? How much RAM memory you actually need will depend almost entirely on what kind of activity you plan on using your computer for. And while there are going to be some borderline use cases where the amount of RAM you need is going to be fuzzy, this is generally a good breakdown of how much memory y...
