1.8 Internal Memory 1.8.1 RAM (Random Access Memory)
Random access memory (RAM) is the memory in a computer that is used to store computer programs while they are running as well as any other information the programs need to do their job. Information in the RAM can be read and written quickly in any order. Usually the RAM is emptied every time the computer is turned off. It is known as 'volatile memory'.
1.8.2 ROM (Read-Only Memory)
ROM is a memory chip where crucial system instructions (BIOS) are permanently stored. The data held on ROM can be read but not changed. This is done during manufacturing of the ROM chip. ROM is non-volatile, so the data stored on it will not be lost when the computer is

1058 Words | 5 PagesBreak Point 6.2 I think that the students are trying to describe what most people cannot: the effect that music has not on our minds, but our bodies.

401 Words | 2 Pages1. How does DNA encode information? DNA is a double-stranded helix composed of a phosphate backbone and deoxyribose, and encodes information by the sequence of its nucleotide bases, which are composed of adenine, thiamine, guanine and cytosine. DNA undergoes transcription, which produces single-stranded mRNA, which uses uracil in place of thiamine. Next step is translation, in which the RNA becomes a protein, which then can act as structural units or enzymes.

314 Words | 2 Pages3.1.1 Dual Clock In this technique it is assumed that delay misses rarely happens, then circuit schedules are designed using minimal delays for critical paths. Pair of alternate clocks, fast and slow, is used. The system normally operates at the fast clock however, when an error is noticed, computation for the input values which is causing error is restarted at the slower clock. Under the premise that delay errors occur for small number of input values, the system can switch back to the faster clock on the next input value.
