Answer:

1. Natural Language Interface- Telephone users

2. Menu Driven Interface- Automated Teller machine users.

3. Graphic User Interface- Computer users

4. Form-based interface- Website visitors

5. Command-line interface- Advanced users of computers

Explanation:

User interface refers to the hardware and software features in a computer system which makes it easier for the operators to relate with the system. Some of them include;

1. Natural Language Interface- This software feature allows the user to send oral instructions to the computer system. Telephone users experience this when they give oral commands to their phones.

2. Menu Driven Interface- Contains buttons and a touch screen feature that allows users to enter commands in a menu. Automated teller machines used by bank customers are menu-driven interfaces.

3. Graphic User Interphase- Involves the use of the cursor to draw images using graphic icons. Graphic designers can use this to create images.

4. Form-based Interface- Basically contains fields with boxes and menus that would need to be completed. For example, job seekers have to complete fields and boxes before they submit a job application form online.

5. Command-line interface- Is characterized by basic commands which are to be entered by the user to the computer. Advanced users of computes use this feature.

Select the focus questions that emphasizes what is more important: (Select all that apply) a.What needs to be relegated to the b

agasfer [191]

Answer:

Options b and d

Explanation:

Option B: What needs to be bigger and more prominent?

This gets the more foucs on the first look of the product to the user. Let's say you are developing a website and in the first page, your name and logo must be prominent and bigger than the rest of the elements on that webpage makes the user remember your name and the business model which gets more focus.

Option D: What needs to be brought into view in the foreground?

As the index says, face is the index of the mind, your product's index page is the face of your product. Hence it should be prioritized to show what is important and what is not.

The above two questions are the most important questions to be considered while emphasizing on what is more important.

Suppose that a computer can run an algorithm on a problem of size 1,024 in time t. We do not know the complexity of the algorith

Setler79 [48]

Answer:

Time Complexity of Problem - O(n)

Explanation:

When n= 1024 time taken is t. on a particular computer.

When computer is 8 times faster in same time t , n can be equal to 8192. It means on increasing processing speed input grows linearly.

When computer is 8 times slow then with same time t , n will be 128 which is (1/8)th time 1024.

It means with increase in processing speed by x factor time taken will decrease by (1/x) factor. Or input size can be increased by x times. This signifies that time taken by program grows linearly with input size n. Therefore time complexity of problem will be O(n).

If we double the speed of original machine then we can solve problems of size 2n in time t.

In memory ads for DIMMs, you notice DDR 2400 CL15 in one ad and PC4 21300 CL9 in another. Which ad is advertising the faster mem

Artyom0805 [142]

Answer:

The answer is 'PC4 21300 CL9".

Explanation:

Faster memory advertising is used to provide customer memory, which is essential for brand actions. It can't be taken throughout ad coverage. Retired-laboratory tests revealed its access to ad-memory detection aspects of the effect of its grade through publicity recovery, that's why it uses the PC4 21300 CL9, it transfers the 170400 bits per second.
