what do you understand by computer memory for class 2

As when you search for micro SD cards on any e-commerce you get lots of memory cards with lots of specifications different storage different class different sizes. NOT interchangeable. Memory – With respect to class 5 Computer Memory, the device used to store data for a short-term or a long-term is called memory. Memory can be accessed on the rising edge of the system clock pulse. To understand the way memory works, you need to know what a "bus" is. 2 Memory consists of computer chips that hold data.. One type of memory, called Random Access Memory (RAM), forms the central pool of memory that a computer uses to operate. But instead of wires, a circuit board uses copper "traces" inside or on the surface of the circuit board. b) Arithmetic and Logic Unit For example (RAM)Random Access Memory is a volatile memory that store information or an integrated circuit used by the operating system software and hardware. 2. If you want to upgrade your computer’s memory, you need to know what kind of memory it needs. name it parts 2 See answers Debolina11 Debolina11 Computer memory is any physical device capable of storing information temporarily or permanently. To understand storage classes and scope in detail, first we need to know more about how the compiler/computer stores variables in the computer’s memory. CBSE Notes for Class 9 Foundation of Information Technology – Concept of Memory. Without RAM, doing just about anything on any system would be much, much slower. When used by itself, the term RAM refers to read and write memory; that is, you can both write data into RAM and read data Easy notes that contain overview and key points of the chapter. Each cell holds one binary data bit, either 0 or 1. In fact, a computer consists primarily of memory. The capacity of each location to store data is same. The term primary memory is used for storage systems which function at high-speed (i.e. "Double Data Rate". Since response time, complexity, and capacity are related, the levels may also be distinguished by their performance and controlling technologies. This one is easy to understand, since you have used files and files sytems e.g. Digital computer, any of a class of devices capable of solving problems by processing information in discrete form.It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code—i.e., using only the two digits 0 and 1. When you turn on the computer, most of the boot time is as the operating system is being loaded from the computer's main storage unit -- likely a hard drive -- to the system memory. Check how much RAM your computer and operating system can support. Here are just a few examples of the many items that use memory: Computers are capable of storing data and instructions and retrieving them. It comes in two speeds: 266 MHz (PC2100) and 333 MHz (PC2700). If you want to upgrade your PC's memory, be sure to use the correct type of memory for your system board. Nowadays, generation includes both hardware and software, which together make up an entire computer system. As we know that the memory management of computer system is one of the important features of the operating system. Dinesh authors the hugely popular Computer Notes blog. This is the hardware. The CPU requests step-by-step instructions from memory, which tell it how to draw the letter B. Because a computer needs millions of memory cells in order to operate efficiently, the cells have to be cheap. 100 separate 1 GB video files .. need 100 GB of storage capacity Pictures of Hardware. In computing, memory refers to the devices used to store information for use in a computer. Before we look at the different types of memory, let's first ensure that you understand the purpose of memory. Some system boards made by Intel use Rambus DRAM (RDRAM). Memory, or RAM, plays a big role in the speed and performance of a PC. Each location or cell has a unique address, which varies from zero to memory size minus one. As you can see, we use the number “2” or “3” after “DDR” or “PC” to indicate that we are talking about a DDR2 or DDR3 memory, not DDR. Modern computer systems use DDR memory, which stands for http://www.test-king.com/exams/EC0-350.htm, http://www.actualtests.com/exam-HP0-S36.htm. It can store or retrieve a word from any memory address at random, hence the term "random access memory" (RAM). Not all SD cards offer the same speeds. Level 2 or Cache memory – It is the fastest memory which has faster access time where data is temporarily stored for faster access. There are several different types of memory: RAM (random-access memory): This is the same as main memory. A computer that has 1 megabyte of memory, therefore, can hold about 1 million bytes (or characters) of information. The type of memory matters to the performance of a computer. You’ll take a look at the underlying concepts of how computers work and what’s happening behind the scenes when you run your computer programs. People know two types of memory, and that is good. Dinesh Thakur holds an B.C.A, MCDBA, MCSD certifications. The most important signal racing around the system board is known as the "system clock signal". The previous discussion becomes a little clearer if you understand how memory addresses work in a computer's hardware.
