1. Certain types of attacks have been made more potent by which of the following advances to microprocessor technology? a. Increased circuits, cache memory, and multiprogramming b. Dual mode computation c. Direct memory access I/0 d. Increases in processing power

d. Increases in processing power

Explanation:

Due to increased processing power, the attackers are now able to crack the passwords and able to decrypt the encrypted text, which is encrypted using very tough encrypting algorithms. The current day processors can process quite a good number of instructions per second. The increased circuits, multiprogramming and cache memory do not make a certain form of attacks more effective. The multiprogramming is being applied to run the antivirus software, email clients firewall and word processors run at the same time, and cache memory is used to ensure very high-speed reading and writing. And there is no dual mode computation when examining the microprocessor advances. And the Direct memory access is the method or transferring the instructions and data in between the i/O devices and the system memory without making use of the CPU. And hence, it increases the speed of the data transfer to a great extent. It offloads the work from the CPU as more simple instructions are being interpreted and executed through the processing power of the computer system. And it is by no means the advancement of microprocessor technology, And hence, the correct option is D.
