Computer specification (Hardware)

Computer hardware specifications are technical descriptions of the computer's components and capabilities. Processor speed, model and manufacturer. Processor speed is typically indicated in gigahertz (GHz). The higher the number, the faster the computer. Random Access Memory (RAM), This is typically indicated in gigabytes (GB). The more RAM in a computer the more it can do simultaneously. Hard disk (sometimes called ROM) space.  This is typically indicated in gigabytes (GB) and refers generally to the amount of information (like documents, music and other data) your computer can hold. Other specifications might include network (ethernet or wi-fi) adapters or audio and video capabilities.

Language : large and small numbers

For decimal values, we say “point” for the decimal points and pronounce the next numbers individually. We don’t always mention the 0 to the left of the decimal point for values ;less than 1	It’s 0,54 millimeters long (‘nought point five four or “point five four. NOT “nought point fifty-four)
To express large and small numbers, we often use prefixes. For example, kilo-means 1,000. the main stress is on the first syllable of the prefix	A 3,6-killobyte file

Language : giving instructions

We often use imperatives to given instructions. We use “softener” such as could you, can you and just to make the instructions sound more polite.	Drag the window to the left Could you just double click on the bottom icon?
We use sequencers (e.g. first, then, next, after that, finally) to show the order of the steps	First, just click on the “start button. Then select “shut down” in the bottom right corner.
