Answer:

The answer to this question is given below in the explanation section

Explanation:

First,  we need to know what is abstraction and refinement.

Abstraction and refinement are used in application/system development in the field of computing. Abstraction is used to abstract the details from the model. It means that displaying only essential information about the the model and hiding other details. While refinement is the idea that is used in software development by moving through each level of abstraction and incrementally refining each level of abstraction, providing more detail at each increment. Refinement is the inverse of abstraction.  

So the correct options to this question are:

  • Models may be abstracted and refined depending on the goals of the project.
  • Abstraction is a technique used in computational thinking.
  • Refinement is the inverse of abstraction.

In a multiprogramming and time-sharing environment, several users share the system simultaneously. This situation can result in
kap26 [50]

<u>Explanation:</u>

a.

  • One user can read the private data of another user-privacy.
  • One user can prevent another user from getting anything done-denial of service.

Indeed, in any multiprogramming and time-sharing environment since the computers of users are networked together, then it is very possible for a bad actor to read the private data of another user, or even prevent another user from accessing their computer by employing a denial of service attack on the network. In other words, the network would be unable to handle the request of users since has been overloaded by another user.

b. a. Yes - if we can ensure that the operating system prevents any sharing of data between users, either for reading or writing and fairly shares the computer, then we can achieve the same level of security.

Create a website on budget
kaheart [24]

Answer:I bet your attention automatically tuned into the video background, right?  It’s almost impossible to ignore it as it is moving.

There’s nothing wrong with you – it’s just human nature and how we subconsciously decide where to pay our attention to.

We are easily distracted by anything that moves – just like that dog that ignores everything in its world to chase that pesky little squirrel!

“Okay, you got me to look at your silly video, what does this have to do with my website design?”

What a great question and I’m glad you asked.

A video background on your website, if used properly, can help you capture your website visitors’ attention too!

Video background is one of the most popular website design trend that seems to be here to stay.

Marketers love video backgrounds because they make websites look modern and create a sense of artistry that static background images simply can’t match up to.

Many website conversion experts and regular people alike see their visitors stay on their websites longer and more likely to sign up or opt-in to their product / service offers.

I’ll admit – a 138% improvement sounds extraordinary and challenging to achieve every other day.

Keep in mind that such high figure is from tests ran by conversion / business optimization professionals who do this for a living. So it’s fair to say not everybody who runs a DIY website will see similar improvements, just by adding a video background to their website.

However, even a 10% – 20% improvement in engagement and conversion is not unreasonable for even a first-time website owners with no professional help  – if you use video background on your homepage the right way!

Imagine if you collected email newsletter subscribers so you can follow up with special promotions or share interesting discussions to build your brand.

Consider what a 20% increase in subscribers can do to your business? This can mean more sales and/or higher brand awareness!

All this can be done if you can capture your visitors’ attention more effectively – by using a video background.

This is not just a hypothetical idea. A lot of real life case studies have demonstrated how many businesses have succeeded by using video backgrounds to improve sales.

Like all things in life, there is a right way and a wrong way of doing things.

Even with something as groundbreaking as a video background, you can still screw it up and end up hurting your overall website design and experience – if you don’t abide by some basic rules.

So, understanding how to avoid basic mistakes when using a video background on your homepage can give you a much higher chance of succeeding in improving your web design.

In this guide, we will show you all the steps and best practices you should take to use video background effectively:Video background is most effective when you use it to (1) create a vibe, (2) to set a tone or (3) to induce an emotional reaction.

Let’s check out some examples:

Example #1: Businesses, Services, Organizations

Video backgrounds work for most professional websites, whether you are running a clinic, consultancy business, or design agency.

You can use a video background to show clips of the life of your staff or even the process of helping a customer. This gives your potential clients a chance to get to know you before even talking to you. It also paints a very vivid visual representation of what they can expect to experience from your business.Grain & Mortar is a design agency. This example is interesting because it shows you that you don’t always need to have a full page video background to get a similar benefit. They only display a video in the header section of the page that takes no more than half the screen real estate.

The video shows the daily collaboration of the staff (strategy sessions) and how they create design solutions for their clients.

At this moment, video background themes are somewhat limited in Shopify’s Theme Store. You do get more selection if you search for Shopify Video Background Themes in third party providers like Themeforest.

Do keep in mind all themes available in Shopify’s Theme Store are screened, approved and supported by Shopify.

In comparison, Shopify Themes from third party providers do not undergo Shopify’s direct screening process. While I am not saying third party themes are not as good, I just want you to be informed if you are considering whether to purchase from a third party provider.

Which statement describes a characteristic of SRAM in a PC?
svlad2 [7]

It is used for cache memory.

Further Explanation:

Cache memory is the memory that stores the instructions and data that is used repeatedly. If the processor wants some data it first looks into cache memory then the processor doesn't has to look into the main memory for the data or instructions which is more time consuming. As the SRAM uses small but a constant source of power, it is usually used for making cache memories. Moreover it is benficial to keep the previously used data in SRAM(Which is faster) than acessing DRAM (Which is way more slow than SRAM.
