Answer:
IBM's own Personal Computer (IBM 5150) was introduced in August 1981, only a year after corporate executives gave the go-ahead to Bill Lowe, the lab director in the company's Boca Raton, Fla., facilities. He set up a task force that developed the proposal for the first IBM PC.
Answer:
Your “digital footprint” includes all traces of your online activity, including your comments on news articles, posts on social media, and records of your online purchases. When you know the boundaries of your digital footprint and take steps to contain it, you can help protect your identity and your reputation.
Explanation:
You have an application deployed in Oracle Cloud Infrastructure running only in the Phoenix region. You were asked to create a disaster recovery (DR) plan that will protect against the loss of critical data. The DR site must be at least 500 miles from your primary site and data transfer between the two sites must not traverse the public internet. The recommended disaster recovery plan is
<u>A. Create a new virtual cloud network (VCN) in the Phoenix region and create a subnet in one availability domain (AD) that is not currently being used by your production systems. Establish VCN peering between the production and DRsites.</u>
<u></u>
Explanation:
- Local VCN peering is the process of connecting two VCNs in the same region and tenancy so that their resources can communicate using private IP addresses without routing the traffic over the internet or through your on-premises network.
- You have a central VCN that has resources that you want to share with other VCNs.
- A VCN is a customizable private network in Oracle Cloud Infrastructure. Just like a traditional data center network, a VCN provides you with complete control over your network environment.
- A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments.
- A VCN resides in a single Oracle Cloud Infrastructure region and covers a single, contiguous IPv4 CIDR block of your choice.

Advantages of Analog computers:
- Many data parameters can be obtained concurrently in a simultaneous and real-time procedure.
- Certain operations can be computed without the need of converters to transform the inputs and outputs to and from digital digital mode.
- The developer must scale the problem for the computer's dynamic range during configuration. This might provide insight into the issue as well as the consequences of numerous faults.
Disadvantages of Analog computers:
- Computer systems can handle greater issues for a certain efficiency and power usage.
- Solution arise in real or delayed time, and recording them for subsequent use or investigation might be problematic.
- The number of temporal variables that can be used is restricted. It's tough to correctly solve problems with elements that operate on radically various time periods.
Advantages of Digital computers:
- It is a lot more efficient and more effective, particularly with today's computers, which can analyze information at a billion times the rate of a human.
- Modern digital computers' incredible speed enables them to recreate objects in real time, resulting in new experiential characteristics of digital computers, such as interactive media.
- It has the ability to convey information in a very brief manner. This enables data storage and transmission to be more efficient as digital systems are extremely dependable and controllable.
Disadvantages of Digital computers:
- To complete the same tasks, digital computers need more power than analog computers, resulting in greater heat, which increases the complexity of the computer and necessitates the usage of heating elements.
- To convey the same amount of data, digital computers require more capacity than analogue computers.
- The detection of digital computers necessitates synchronization of the computer system, which is not always the scenario with analogue computers
