Hi There!
So, to help explain what a computer system or help gain an understanding, I am going to use a analogy. What I mean by that is how a computer system may be compared to a automobile.
An automobile is made up of a variety of pieces, including an engine, gearbox, axles, wheels, a battery, gears, and other electronics. The components are all interconnected within a frame and function as a whole to enable the car to travel down a road. There is also a driver. By interacting with or physically directing the steering wheel to do certain actions, such as driving straight ahead, turning left, or turning right, the driver controls the vehicle.
The computer system is like a car in that it merely consists of many pieces. The hardware consists of a CPU, memory cards, storage, and other electrical components. The hardware is arranged in a frame and interconnected so that the user may command the computer to do particular tasks. The user and the computer system must interface or communicate. The computer system features a keyboard and mouse instead of a steering wheel, which enables the user to interact with or direct the computer to do activities like opening a file, creating a document, or printing a page.
This comparison should help you understand what a computer system better.
Cheers!

The sites that appear at the top or on the side of the results page are usually those that <u>have paid for there presence on the home page.</u>
Explanation:
It takes a fortune to list on the top or side of the search engine's result page (SERP). Presence on the top or side of the result page guarantees enhanced visibility and increased conversion chances.
The web content masters who are in the need of such strategic advantage often pay for it. The search engine such as Google, Yahoo charges them based on their preferences, content length and the target region. However, with adequate search optimisations, one can make his/her site appear on top in the search page list.
Using a wireless technology known as Near-field communication (NFC), once activated on the smartphone, allows payments or purchases to be made at select stores.
<h3>What is Near-field communication (NFC)?</h3>
NFC is a set of short-range wireless technologies that typically require a distance of 4 cm or less to initiate a connection.
<h3>Characteristics of Near-field communication (NFC)</h3>
- For it to work, it is necessary to place two spiral-type antennas within these close electromagnetic fields.
- This technology is built on radio frequency identification, which allows a gadget to send radio waves to another gadget or another tag and trigger a certain action.
- The NFC acts on the smartphones just like the RFID chips of the bank cards with which you can make payments or purchases.
Therefore, we can conclude that the NFC allows two devices to exchange data when in close proximity to each other.
