 Backing storage comes in various forms for shell compact disks and diskette disks. Backing storage is a portable and cheerful way of saving training. To reduce the risk of selective entropy button it is fool austerey to save information on the computers hard drive and make a copy onto a disk or a nonher type of musical accompaniment storage for insurance purposes. Types of backing storage  Floppy disks The most special K storage device available, these provide extremely cheap storage and tolerate a capacity of 1. 5 Mb.  Compact Disk (CD-ROM) These have been employ for some years as storage devices for computer software.It provided accesses information which is already stored on it and is able to store 650 Mb of information.  Zip Drives A storage device that has become popular over the last a few(prenominal) years because it offers the convenience and portability of a floppy disk, combined with a carbon Mb capacity.  CD-R and CD-RWThe difference bein g that CD-R disks give the axe only have info saved to them once, While CD-RW can be utilise in the selfsame(prenominal) manner as other storage devices having data saved to them on a re-usable basis.  DVD (digital versatile disc) using the same basic principles as the CD, DVD packs the data more than densely and can store 4.7Gb compared with the CDs 650Mg, can h centenarian 133 minutes of video, with Dolby surround sound. Data pens A new storage device that plugs into the computers USP drive. These are petty and compact and have a capacity of 80Mb.  Magnetic Tape snug and cheap medium for backing up hard disks onto computers. Mostly utilise for mainframe computers for storing information for a long duration. Magnetic tapes will not be suitable for a small company like apostate Plc. Data Protection Craven Plc must comply with the data tribute act in order to hold personal information of customers.The data protection act works in two ways. It gives you certain right s. It as well as says those who record and use personal information must be cleared about how the information is used and must follow the eight principles for levelheaded handling. The eight principles were put in place to make sure that your information is handled properly. They say that data must be 1. Fairly and lawfully processed. 2. process for limited purposes. 3. Adequate, relevant and not excessive. 4. Accurate. 5. Not kept for longer than is necessary. 6. processed in line with your rights. 7. Secure, and 8.Not transferred to countries without adequate protection. Micro computers Micro computers accept personal computers and laptop computers, they are usually equipped with hard disk, floppy disk drive, between 1 and 32 megabytes of memory, a keyboard and a visual display unit unit. Microcomputers will be suitable to fulfil the needs of Craven Plc. central processor Computers These are large systems that can hold vast amounts of data. Mainframe computers gratify a wh ole floor of a fair sized building. These healthy mainframe computers are present in very large companies storing considerable amounts of data on to disk.Mainframe computers cost tens of thousands of pounds, therefore they are not suitable for a small business like Craven Plc. send cabinet Server This is a specially configured microcomputer to control the veer of files between network users. A file server also has more memory and disk storage than normal microcomputers. These classifications of computers are usually ground on physical size, speed, processing capabilities, memory size, disc storage, capacities and cost. Direct and consequent Access Direct access devices can go instantaneously to the file or record. For example a CD can go directly to track number 10.Sequential access devices have to run done the file sequentially, for instance, if we want track 10 on a cassette, The cassette moves from the send-off from track 1 to 9 until it comes to track 10. 4) Proposed p urchases and prices of equipment 2x Sony Intel 2. 6GHZ DVD CDRW Laptop  256Mb RAM, 40Gb aphonic Drive DVD/CDRW Drive  15 inch TPT screen i?? 899 for each one = i?? 1798 4x Packard Bell 6111 Intel Pentium 42. 8GHZ processor and 15 TFT monitor  Intel P4 2. 8 GHz processor * 512 Mb RAM  160 GHb problematical Drive i?? 1199 each =i?? 4796 4x PacKard Bell 5050 and Xp2600+ PC and 17 CRT monitor  Athlon Xp 2600 & processor  256Mb RAM.60 Gb hard Drive i?? 549 each =i?? 2196 4x Hewlet Packard DJ 9300 A3 Desktop newspaperwoman i?? 279 each =i?? 1116 3x Hewlet Packard scanner i?? 99 each =i?? 396 Network- Windows 2000 professional i?? 3449 web Designer Approx 3000to4000 Training cost i?? 2000 Specialist soft ware Sage Accounts i?? 2000 Web Train Video Conferencing i?? 1000 Total cost i?? 22751 5) Proposed method of flip-flop over from manual to the new computerised systems Before the change over can take place an extensive training create by mental act needs to take place. This may take several months to train the reliable workforce in the correct operating procedures of the new system.To ensure information will not be lost in transition the old manual method needs to be in place for the start-off 2 months along side the new computerised system. In the unlikely content of system collapse information and data will still be on hand. This change over will inevitably endure a small cost of training and staff development. 6) Procedure to transfer the paysheet from the old to the new system Payroll is something Craven Plc cannot afford to render wrong. Therefore manual systems need to be in place for 3-4 months along side the new computerised sage accounts system. This will again ensure against loss of data.
