Text, numbers, pictures, audio, and nearly any other form of information can be converted into a string of bits, or binary digits, each of which has a value of 1 or 0. A memory is just like a human brain. RAM chips only keep things in their memory until the power is turned off. Memory devices utilize integrated circuits and are used by operating systems, software, and hardware. 4. List at least three kinds of information stored in a computer. Storage media includes disk drives, flash drives, media cards, and CDs and DVDs. Memory is where the processor does its work, where programs run, and where information is stored while it’s being worked on. 4. 1 Answer to 1. If your computer's CPU had to constantly access the hard drive to retrieve every piece of data it needs, it would operate very slowly. Media storage is the place where things go when the microprocessor isn’t directly working on them — but from where stuff can be retrieved later, if need be. For example, if the computer has 64k words, then this memory … The information in the RAM is stored in the form of hundreds of electronic circuits. This is the main memory of the computer. RAM gives applications a place to store and access data on a short-term basis. Computers remember things in a very different way from human brains, although it ispossible to program a computer to remember things and recognize patterns in a brain-like wayusing what are called neural networks. The BIOS operates the fun… The type of data being stored also determines how much you can fit on a memory card. Add to your Knowledge The memory from which we can only read but cannot write on it. Therefore, it is used only for short-term memory storage. The full form of RAM is Random Access Memory. All the information that CPU use, is stored and accessible from the primary memory. Types of RAM 4. It's called dynamic because it needs to be periodically refreshed or the data gets lost. Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. ROM stands for Read Only Memory. A ROM stores such instructions that are required to start a computer… The shortest type of memory is known as working memory, which can last just seconds. This allows the CPU direct access to the computer program. Understanding your computer's memory and how it works will help you better understand certain aspects of C programming.
