Answer:
Tout calculateur électronique ou numérique nécessite une source d'alimentation pour fonctionner, avec son circuit configuré à la porte logique requise liée aux touches d'entrée et à l'écran de sortie.
Explanation:
Les calculatrices sont des appareils utilisés pour les calculs arithmétiques. Au 19ème siècle, les calculatrices étaient mécaniques et n'utilisaient pas de batterie, elles étaient encombrantes et utilisaient des tiges et des engrenages dans leur fonctionnement. Les calculatrices récentes sont électroniques, alimentées par une batterie. Ils comprennent un circuit électronique configuré à sa porte logique requise pour le calcul, un bouton pour l'entrée et un écran pour la sortie du calcul.
An array of integers named parkingTickets has been declared and initialized to the number of parking tickets given out by the city police each day since the beginning of the current year.
Explanation:
- A variable named ndays has been declared and initialized to hold the size of the array.
- The first element of the array contains the number of tickets given on January 1; the last element contains the number of tickets given today.
- A variable named mostTickets has been declared, along with a variable k.
- If today were January 18, ndays would have the value 18; if today were February 3, ndays would have the value 34
mostTickets=0;
for (k=0; k< ndays; k++)
{
if (parkingTickets[k]>mostTickets) mostTickets=parkingTickets[k];
}
Technologies that can operate in the 125 kHz to 134 kHz range is the
B. RFID
Explanation:
- RFID is technology which works on radio frequency and it is used for the auto-identification for the different object.
- The RFID system mainly consists of two parts. In this RFID system, this RFID reader continuously sends radio waves of a particular frequency
- RFID is the use of radio waves to read and capture information stored on a tag attached to an object, providing a unique identifier for an object.
- Active RFID tags have a transmitter and their own power source. Instead, they draw power from the reader, which sends out electromagnetic waves that induce a current in the tag's antenna.
- Semi-passive tags use a battery to run the chip's circuitry, but communicate by drawing power from the reader.
- Radio frequency identification (RFID) can operate in three frequency bands: 125 kHz to 134 kHz, 13.56 MHz, or 856 MHz to 960 MHz. Bluetooth is 2.4 GHz; NFC is 13.56 MHz; and LTE is between 600 MHz and 6 GHz.
Answer:
C. control unit.
Explanation:
A processor is a miniaturized central processing unit a in digital system that interconnects and controls the activities of other components in the device.
The components of a microprocessor are the bus, registers, cache memory, arithmetic and logical unit and the central or control unit.
The bus is the transportation medium for all activities in the processor. The registers like the accumulator and the B register are memory locations used to hold the operand of an operation.The cache memory holds data meant for immediate use by the processor. Arithmetic and logical unit carries out the various arithmetic and logical operation in the processor, while the control unit is responsible for handling or managing all activities in the processor.
