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.

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 which

The basic idea of RAID was to combine multiple small‚ inexpensive disk drives into an array of disk drives which yields performance exceeding that of a Single Large Expensive Drive (What is RAID?). 3. a. RAID Level 0 is not redundant‚ hence does not truly fit the "RAID" acronym. In level 0‚ data is split across drives

Overclocking a processor What is overclocking? It is a procedure of increasing your PCs performance by increasing your CPUs/RAMs/Southbridge’s/Northbridge’s/GPUs clock and multiplier (only CPU and RAM) and voltage. In this text I am gonna explain you how can you overclock your CPU and RAM. About others I will maybe explain you some other time. Why would anyone want to overclock (OC) a processor? Because it increases computers performance. But it also increases CPU-s temperature‚ so it needs a better

The need for more storage is growing. The amount of data produced is doubling in every two years. (in 2010 – 1.8 zettabytes) The cost of creating‚ managing and storing the data is decreasing‚ but can the optical storage expand further? The current Blu-ray lasers emit light in the blue part of the electromagnetic spectrum (about 420 nanometer wavelength). There are ongoing researches using UV light‚ that would probably have to be 200 nm and would provide storage capacities of over 100 GB in a single

• A server is a computer that is a meant to be a dedicated service provider‚ and a client is a computer that requests services. • Before selecting the hardware and software components of a server‚ you should identify the server roles and network services that the server will need to provide and how many people will be accessing the server at once to help determine the load the server needs to fulfill. • The primary subsystems that make up a server are processor‚ memory‚ storage‚ and network

There are two types of memory RAM (random access memory) and ROM (Read-only memory). With memory a computer is able to hold applications‚ operating systems and saved files such as documents. Understanding the difference between the two types of memory is key. RAM is a volatile memory meaning the data can be lost when power is interrupted if not saved to a disk or hard drive. While ROM is a nonvolatile memory meaning data is not lost when power is interrupted. RAM is usually found in dim sticks
