  1. Essential Roles of a Virtualization Hypervisor:

    • (b) Scheduling CPU time slices 4 each virtual machine.
    • (c) Exposing custom virtualized hardware.
    • (d) Allocating system resources across guest operating systems.

    Hypervisors R responsible 4 managing virtual machines by allocating resources & scheduling CPU time. Direct disk access is typically managed through the hypervisor but is not considered a direct role of the hypervisor as it involves more direct interaction with the guest OS.

PIC18 Microcontroller Overview

CPU Architecture

The PIC18 microcontroller features a powerful CPU with the following key components:

  • ALU (Arithmetic Logic Unit): Performs arithmetic and logical operations.
  • Instruction Decoder: Decodes 16-bit instructions.
  • Status Register: Stores 5-bit flags indicating the CPU’s state.
  • WREG: An 8-bit working register used for temporary data storage.

Registers

The PIC18 provides various registers for program execution and data management:

  • Program Counter (PC): A 21-bit register

Basic SQL Statements

DDL Commands

DDL (Data Definition Language) commands manage the structure of database objects. They are auto-committed, meaning changes are saved permanently. Common DDL commands include:

  • CREATE: Defines tables and their columns.
  • ALTER: Modifies existing tables.
  • DROP: Deletes tables and their data.
  • TRUNCATE: Removes all data from a table.
  • RENAME: Changes the name of a table.

CREATE Command

The CREATE command defines a table’s structure, specifying column names and data types.

Syntax:

CREATE
