Without them, the revolution of current computer and information-technology would not exist. 2. A multimeter is a general-purpose meter capable of measuring DC and AC voltage, current, resistance, and in some cases, decibels. 3. When measuring current, the circuit must be opened and the meter inserted in series with the circuit or component to be measured. 4. Moores law, which predicted that the number of devices integrated on a chip would be doubled every two years, was accurate for a number of years. 得 分五、综合运用(每小题 20分,共 20 分) C is commonly considered to be a structured language with some similarities to Pascal. In C, a block of code is a logically connected group of program statements that can be treated as a unit. You can create a block of code by placing lines of code between opening and closing curly braces. For example:if(x10) printf (“too low, try again”); reset_counter(-1);The two statements after
