Answer:
Modern CPUs contain multiple cores. Think of it as multiple smaller CPU's on the single CPU chip. The multiple cores can handle different processes in parallel allowing for multiple programs to be running at the same time. This is not considered true multi-processing since the architecture still has a single I/O bus and can be subject to a single point of failure. But the operating system will take advantage of the additional cores as if they were multiple physical CPU's - enhancing performance and productivity.

Answer:
In binary signaling, Non Return to Zero (NRZ) is the technique in which zero voltage is represented by 0 bit while high voltage is represented by 1 until the voltage level change from high to low.
Explanation:
There are different techniques to encode the signal for transmission between transmitter and receiver. These techniques includes return to zero, non return to zero. In return to zero technique, the if the voltage is high the signal will become 1 for half of the time period and then after half time period it return to 0.
In NRZ the signal is 0 if the voltage level is zero. In case of high voltage of the signal the binary bit remains 1 until the next zero voltage level arrive in the signal until the end of the time period of bit.
Answer:
The correct answer to the following question will be "Trojan programs".
Explanation:
- A trojan is a kind of software often identified as legal applications. Internet-thieves and hackers will hire Trojans and they were trying to access to consumer programs. Users are usually fooled into launching and operating Trojans on their devices by a certain form of economic manipulation.
- It's a kind of malicious software that express themselves as helpful applications and programs.
Therefore, the Trojan program is the right answer.
