Final answer:
Amazon VPC is the AWS networking service that enables a company to create a virtual network within AWS.
Step-by-step explanation:
The AWS networking service that enables a company to create a virtual network within AWS is Amazon VPC (Virtual Private Cloud).
Amazon VPC allows you to provision a logically isolated section of the AWS Cloud, where you can launch AWS resources such as Amazon EC2 instances, Amazon RDS databases, and more.
By creating a virtual network with Amazon VPC, you can control the network configuration, IP address range, subnet, security groups, and routing tables, providing a secure and customizable environment for your company's infrastructure.
