Consider a 4-drive 200gb-per-drive raid array.what is the available data storage

It depends on what RAID you're using. Some RAID arrays use multiple drives for redundancy. Therefore, if all four of those drives were on this kind of RAID array, then you would only have 200GB of available storage, as data is duplicated.

In other RAID arrays, speed and performance is the main goal, where data is spit between the four drives, meaning there would be a total of 800GB of available storage.

Finally, you could have a mix between the two if you liked, where 2 drives are paired up in the redundancy RAID, as are the other two. The two pairs are then put up in the performance RAID, allowing for a total of 400GB of available storage.

Long story short, it depends on what kind of RAID you're using, and there are many more RAID configurations than I have mentioned here.

What is the definition of Graphic AIDS?.

V125BC [204]

Any image that helps you, the reader, understand the text that the visual aid is accompanied with is referred to as a visual graphic or graphic aid.

Too frequently, readers lazily scan or entirely ignore graphs, diagrams, charts, and tables. Grid graphs, tables, bar charts, flow charts, maps, pie diagrams, and drawings and sketches are the most popular. Relationships are displayed using grid graphs. A visual aid should always be used in conjunction with preparation to interest the audience, improve their comprehension of your message, elicit an emotional response, and assist you in communicating it effectively. Charts, diagrams, graphs, maps, flashcards, posters, images, photos, booklets, folders, pamphlets, cartoons, and comics are examples of graphic aids.
