T Media Def. and Uses Advantages Disadvantages Magnetic backing storage media Stores the binary data on a disk or tape coated with a material that can be magnetised differently‚ depending on whether a 0 or 1 is stored. used for tertiary and off-line storage. Data stored in backing storage is permanent so it is NOT lost when the computer is turned off. It is always slower to access data from backing storage than from internal memory.

define at least five different types of storage devices from the most reliable to the least reliable. Include in your search cost and availability of the storage devices. Include names of vendors for these storage devices. There are three main types of consumer-grade computer storage: internal‚ external‚ and network attached. Internal storage is generally a hard drive or solid-state drive (SSD) that hosts computer’s operating systems and programs. External storage comes mostly in the form of external

STORAGE DEVICE Definition A storage device can be defined as any piece of hardware whose main function is to store data and information The hardware that writes data to or reads data from a storage medium is called a storage device. Types of Computer Storage Devices Computer storage devices can be classified into o Primary storage o Secondary storage o Tertiary storage Primary Computer Storage Devices Primary storage refers to the computer’s memory(RAM) RAM (Random Access Memory)

Types of Storage Devices Physical components or materials on which data is stored are called storage media. Hardware components that read/write to storage media are called storage devices. Two main categories of storage technology used today are magnetic storage and optical storage. Primary magnetic storage o Diskettes o Hard disks (both fixed and removable) o High capacity floppy disks o Disk cartridges o Magnetic tape Primary optical storage o Compact Disk Read Only Memory (CD ROM)

Types of Storage Devices A storage device is a device capable of storing data. The term usually refers to mass storage devices‚ such as disk and tape drives (www.webopedia.com). In this paper I will explore different types of storage devices and which ones are optimal for different situations. I will also explain what situations are appropriate for the following devices and explain why: a. Hard disk b. Floppy disk c. RAM d. CD ROM e. Tape Hard Disk A hard disk is a magnetic disk on

Limitations of Primary Memory: Limited capacity because the cost per bit of storage is high Volatile - data stored in it is lost when the electric power is turned off or interrupted. So as a result additional memory called auxiliary memory or secondary memory is used. Following are the features of Auxiliary or Secondary Storage: 1. Permanent or Non-volatile Storage: The data which is stored in those devices is not lost when the power is switched off. The data is retained. 2. Voluminous

IS022 3/20/2014 Access Methods of Secondary Storage Devices Secondary Storage Device is storage medium which is used to store large amount of data permanently until it is changed by user. Though it stores information‚ it cannot be accessed directly by the CPU. The data stored in Secondary Storage Device can be accessed depending upon how it is stored on the device. Mainly there are two methods of accessing data from the Secondary Storage Device. 1) Sequential Access Method 2) Direct Access
