1 CAMBRIDGE INTERNATIONAL EXAMINATIONS International General Certificate of Secondary Education MARK SCHEME for the May/June 2013 series 0417 INFORMATION AND COMMUNICATION TECHNOLOGY 0417/22 Paper 2 (Practical Test A), maximum raw mark 80 This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for Teachers. Cambridge will not enter into discussions about these mark schemes. Cambridge is publishing the mark schemes for the May/June 2013 series for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level components and some Ordinary Level components.

So, will you look for a SATA3 drive as your Spellings corrected motherboard supports this? Get lots of storage Header: Candidate details Filename and path You have already, perhaps, a good size hard disk, but on examining it you see that its connection is a parallel ATA system and your new motherboard only supports serial ATA connections. You only had a 500gb drive and now you think that as this was getting pretty full you will need at least a terabyte of storage. If you are seriously gaming or streaming video you may find even this gets full soon. This may seem incredible, but whenever we have installed what seems to be an excessively huge amount Appropriate of storage image that we found will never fill, 1 along mark come Spelling correct, 18 point serif font Underscored, right aligned Use an SSD for the OS For your main storage you will probably use a mechanical hard drive which writes data to a series of platters and has a moving read/write head. There is nothing wrong with these devices, but for speed you might be thinking of Subheads an SSD drive. body These text plus are 14 solid pt and state centred drives which have no moving parts, so are more robust in moving environments such as laptops or tablets. They are also very fast as they use flash memory. The disadvantage of them is that they are much more expensive than mechanical hard disk drives.

One reason is that even in this fantasy world of building a crazy but cool machine there are limits to finance and two 512gb SSD drives will probably cost more than the rest of the project together. Another reason is that currently SSDs are said to slow down rapidly when they have made a lot of writes to the disk. Controllers are being developed to level the wear and they are now said to be better at keeping to their original incredible speed. Hence the plan to use a small SSD for the operating system and programs, and a mechanical hard disk drive for data storage. Here are examples of the cheapest storage devices per GB in our list. Full file path and candidates file name the loss of data on both disks. You will need to make sure you have regular backups of your data. RAID1 configuration mirrors the data on two discs. This gives the security of automatic backup as all data is recorded on both discs and if one disc fails, the other can take over. For speed and security, RAID10 combines both striped and mirrored data using four disks. This now sounds a bit excessive for our gaming machine, but you might consider a pair of SSDs in RAID0 for your operating system.

You might combine disks for speed or security or both. In RAID0, the data is written across two disks as though they were one. This is called striping.
