Control Unit – controls all parts of the computer system. It manages the four basic operations of the Fetch Execute Cycle as follows:
Fetch – gets the next program command from the computer’s memory
Decode – deciphers what the program is telling the computer to do
Execute – carries out the requested action
Store – saves the results to a Register or Memory
Arithmetic Logic Unit (ALU) – performs arithmetic and logical operations
Register – saves the most frequently used instructions and data
Answer:
BlueBorne Attack
Explanation:
If you're using a Bluetooth enabled device, whether it's a smartphone, laptop, smart TV, or any other IoT device, you risk malware attacks that can be remotely performed to take over your device, even without requiring any interaction from your side.
Security researchers have just discovered a total of 8 zero-day Bluetooth protocol vulnerabilities affecting more than 5.3 billion devices - from Android, iOS, Windows and Linux to the Internet of devices (IoT) - using technology short-range wireless communication
Using these vulnerabilities, security researchers at IoT security firm Armis created an attack, called BlueBorne, which could allow attackers to completely take over Bluetooth-enabled devices, spread malware, or even establish a “man” connection. -in-the-middle ”to gain access to device critical data and networks without requiring any victim interaction.
Answer:
Pair Programming
Explanation:
In Extreme Programming XP, pair programming is a practice in which two programmers work together in a pair at one machine, when writing a code.
One of the two programmers is called the "driver" or developer who writes the code and supervises all the changes made to the program.
The other one is called an "navigator" or observer who provides ideas on how the program should be written, observes or reviews it the program, identify the issues or errors in the code, help in code simplifications.
The two developers implements the program, do coding, review the program and check each other's work. They both are required to be equally skilled in order to implement and test the code. This improves the process of the software development. By working in a pair and reviewing and testing the code together, they develop a better code.
