CISSP® Certification Domain 3: Security Architecture and Engineering Video Boot Camp for 2022 - Hardware architecture

The video tutorial covers the basics of computer hardware, including the system unit, motherboard, and peripherals. It explains the CPU's role, its components, and functions like fetch, decode, execute, and store. The tutorial also delves into processes, threads, and multitasking, highlighting differences between multithreading, multiprocessing, and multiprogramming. Memory management techniques such as virtual memory, swapping, and paging are discussed. Finally, the video addresses BIOS functions and security measures like TPM and data execution prevention.

What is the primary role of the Northbridge in a computer system?

• To manage input/output devices

• To store the BIOS

• To control peripheral devices

• To connect the CPU to the RAM and video cards

Which part of the CPU is responsible for performing arithmetic and logical operations?

• Control Unit (CU)

• Arithmetic Logic Unit (ALU)

• Memory Controller

• Northbridge

What is the main difference between multithreading and multiprocessing?

• Multithreading uses multiple CPUs, multiprocessing uses one

• Multithreading uses one CPU, multiprocessing uses multiple CPUs

• Multithreading is for multitasking, multiprocessing is for single tasks

• Multithreading is slower than multiprocessing

What is the purpose of virtual memory in a computer system?

• To increase the speed of the CPU

• To protect the BIOS from corruption

• To use disk space as an extension of RAM

• To allow more programs to run simultaneously

What does the BIOS do during the boot process?

• Manages network connections

• Encrypts data on the hard drive

• Loads the operating system into memory

• Executes user applications

Which security feature helps prevent buffer overflow attacks by randomizing memory locations?

• Memory Protection

• Address Space Layout Randomization

• Trusted Platform Module

• Data Execution Prevention

What is the function of the Trusted Platform Module (TPM)?

• To increase CPU speed

• To manage input/output devices

• To store user data securely

• To secure hardware with cryptographic keys
