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. om .c MARK SCHEME for the May/June 2013 series s er International General Certificate of Secondary Education Page 2 Mark Scheme IGCSE – May/June 2013 Name, candidate number, Centre number Header: Candidate details Filename and path Syllabus 0417 Paper 22 Full file path and candidates file name 1 mark 1 mark Building a Crazy but Cool Computer Spelling correct, 26 point serif font Text italicised, centre aligned 1 mark 1 mark Spelling correct, 18 point serif font Underscored, right aligned 1 mark 1 mark Choosing your storage by: name You will like the SATA connections as each drive has its own cable and your motherboard will have plenty of connectors.

It may only be a fantasy, but in the first two articles we Page layout changes here explored choosing a motherboard and CPU for a maximum speed gaming machine. Then we looked at cases and power supplies. This week we consider storage devices. Get lots of storage 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 Appropriate found markcome excessively huge amount of storageimage that we will “never fill”, 1along Placed here and aligned to top of text and applications that will fill up the space. 01/08/2013 aligned to left margin with text wrapped Resized to half column width with aspect ratio maintained 1 mark 1 mark 1 mark 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.

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.

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.
