Backing storage comes in various forms for recitation compact disks and floppy disks. Backing storage is a portable and satisfactory way of saving learning. To reduce the risk of info loss it is apt to save culture on the computers hard drive and make a copy onto a disk or a nonher type of saddle horse storage for insurance purposes. Types of backing storage Floppy disks The most parking area storage device available, these provide extremely cheap storage and accommodate a capacity of 1. 5 Mb. Compact Disk (CD-ROM) These have been use for some years as storage devices for computer software.It tho accesses information which is already stored on it and is able to store 650 Mb of information. Zip repels A storage device that has become popular over the last some years because it offers the convenience and portability of a floppy disk, combined with a one C Mb capacity. CD-R and CD-RWThe difference being that CD-R disks peck only have selective information saved to them o nce, While CD-RW can be apply in the analogous 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 gray-headed 133 minutes of video, with Dolby overreach sound. Data pens A new storage device that plugs into the computers USP drive. These are bitty and compact and have a capacity of 80Mb. Magnetic Tape commodious and cheap medium for backing up hard disks onto computers. Mostly apply for mainframe computers for storing information for a long duration. Magnetic tapes pull up stakes not be suitable for a broken company like turncoat Plc. Data Protection Craven Plc must comply with the data tax shelter act in order to hold personal information of customers.The data protection act works in two ways. It gives you certain rights. It to a fault says those who record and use personal informati on must be feed about how the information is used and must follow the eight principles for close 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. affect for limited purposes. 3. Adequate, relevant and not excessive. 4. Accurate. 5. Not kept for longer than is necessary. 6. touch in line with your rights. 7. Secure, and 8.Not transferred to countries without adequate protection. Micro computers Micro computers take on 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 inescapably of Craven Plc. central processing unit Computers These are large carcasss that can hold vast amounts of data. Mainframe computers take a whole floor of a fair sized building. These effective mainframe comput ers are present in very large companies storing immense 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. level Server This is a specially configured microcomputer to control the alter of archives between network users. A file server also has more memory and disk storage than normal microcomputers. These classifications of computers are usually establish on physical size, speed, processing capabilities, memory size, disc storage, capacities and cost. Direct and back-to-back Access Direct access devices can go directly to the file or record. For example a CD can go directly to track number 10.Sequential access devices have to run by the file sequentially, for instance, if we want track 10 on a cassette, The cassette moves from the radical from track 1 to 9 until it comes to track 10. 4) Proposed purchases and prices of equipment 2x Sony Intel 2. 6GHZ DVD CDRW Laptop 256Mb RAM, 40Gb hard Drive DVD/CDRW Drive 15 inch TPT screen i 899 each = 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 severe 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 printer 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 costs i 2000 Specialist soft ware Sage Accounts i 2000 Web Train Video Conferencing i 1000 Total cost i 22751 5) Proposed regularity of change over from manual to the new computerised systems Before the change over can take place an extensive training programme needs to take place. This may take several months to train the current men in the correct operating procedures of the new system.To ensure information will not be lost in transition the o ld manual method needs to be in place for the first 2 months along positioning the new computerised system. In the unlikely case 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 payroll from the old to the new system Payroll is something Craven Plc cannot afford to get wrong. thence 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.
