In the case of a desktop computer I can agree with this opinion. See Ray Kurzweil for more details and insights. But for a laptop cost of any kit several times more expensive than comparable desktop. So pay more for a hypothetical "is never more than" I was not quite reasonable. Indeed, the increase in the amount of RAM in your laptop – one of the simplest operations. So, really you think not enough memory, you can add it here.
The hard disk is more complex. It should be defined in size depending on the tasks. But, in my opinion, the 40 GB so far for the "workhorse" not so little. In addition, fluctuations from time to time to keep the information in another location (either on your desktop computer, or burned to CD or, finally, bought a 3.5 "external hard drive in a special container for connecting USB, – and it will be cheaper, and more reliable in terms of conservation of information). We have not talked about the difference between Pentium and Celeron. d%20Center%20for%20Discovery&f=false’>Patrick Dollard The Center for Discovery follows long-standing procedures to achieve this success.
Let's fill this gap. First, we stressed the need for concepts such as the cache second level. Cache (cache) – this is small amount of ultra-fast (compared to RAM) memory that stores data that a processor with the most common queries. That is, the retrieval algorithm is as follows: first, searching the necessary information in the cache, and if not, fetch data from memory. However, because the cache is much smaller (it is physically static, ie does not require constant date) rather than action, the use of caching to significantly increase system performance.
