I.19 match the words with their definitions.
i.20 Look through the table 7. space / time given above and make dialogues using the prompts below. Prompts for Dialogues - 1. What units is memory access time measured ['meʒəd] in? - It is measured in nanoseconds. - What does a nanosecond mean? - It means ‘ one billionth or 10 to the -9th power of a second ’. - What else can be measured in nanoseconds? - Used to measure the speed of logic and memory chips, a nanosecond can be visualized by converting it to distance. In one nanosecond, electricity travels about six inches in a wire. Even at 186,000 miles per second, electricity is never fast enough for the hardware designer who worries over a few inches of circuit path. The slightest delay is multiplied millions of times, since millions of pulses are sent through a wire in a single second. - I see. - 2. How many is ‘ mega ’ I wonder? - It means ‘million’. - What is it abbreviated to? - "M." - What is the precise value of ‘mega’ in computer specifications? - It often refers to the precise value 1,048,576 since computer specifications are usually binary numbers. - And what does MHz stand for? - MHz stands for MegaHertZ, megahertz. that is one million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. Megahertz is generally equivalent to one million bits per second or to one million times some number of bits per second. - MegaHertZ … It’s quite an interesting word. Sounds like German. - MHz is the heartbeat. When referencing CPU speed, the megahertz rating is really the heartbeat of the computer, providing the raw, steady pulses that energize the circuits. I see you know a little of the German language, so it's easy to remember this. The word "Herz", pronounced "hayrtz," means heart. - I really appreciate your explanations. ***
