<u>Explanation</u>

A computer is a multipurpose device that accepts input, processes data, stores data, and produces output, all according to a series of stored instructions. Input is data or information typed, submitted, or transmitted into a computer. Processing data involves performing calculations, drawing graphs, modifying documents, and many more. Output is the result produced by a computer. Processing is handled by the computer’s CPU (Central Processing Unit) and the central processing unit of most modern computers is a microprocessor. A microprocessor executes and manages all logical instructions passed to it and performs tasks involved in computer processing. The instructions that tell a computer how to carry out a task are referred to as computer programs, which are distributed as software. A program is software or set of ordered operations on a computer that performs a particular task or function. A program is created and compiled into a language that the computer can comprehend and then distributed as software. Computers run three main types of software: Application software, system software, and development tools. Application software are programs that help a user carry out a task while a system software helps  the computer system to monitor itself in order to function effectively. On the other hand, development tools are used for creating applications, operating systems, Web sites, and utilities. Digital devices are constructed using tiny electronic components that represent data bits as electrical signals. The system unit houses the system board, which contains several integrated circuits made from semiconducting materials. The essence of digital electronics is the small circuit boards and integrated circuits you see when you open up a digital device. ICs are sets of electronic circuits engraved onto a thin slide of semiconducting material. Computers come in three popular form factors: component, clamshell and slate. Form factor in computer terms refers to the size and dimensions of then device. Clamshell devices have features characterized by a keyboard as the base and a screen on the hinged cover. Those devices configured in the slate form factor have a touchscreen that covers majority of the device’s surface. Many of today's digital devices operate on battery power supplied by Lithium ion batteries. Battery life and lifespan can be extended by following good battery management practices.

Compare the elements of the basic Software Development Life Cycle with 2 other models. How are they similar? How are they differ
Artemon [7]

Answer:

Explanation:

One of the basic notions of the software development process is SDLC models which stands for Software Development Life Cycle models. SDLC – is a continuous process, which starts from the moment, when it’s made a decision to launch the project, and it ends at the moment of its full remove from the exploitation. There is no one single SDLC model. They are divided into main groups, each with its features and weaknesses. The most used, popular and important SDLC models are given below:

1. Waterfall model

2. Iterative model

3. Spiral model

4. V-shaped model

5. Agile model

Stage 1. Planning and requirement analysis

Each software development life cycle model starts with the analysis, in which the stakeholders of the process discuss the requirements for the final product.

Stage 2. Designing project architecture

At the second phase of the software development life cycle, the developers are actually designing the architecture. All the different technical questions that may appear on this stage are discussed by all the stakeholders, including the customer.  

Stage 3. Development and programming

After the requirements approved, the process goes to the next stage – actual development. Programmers start here with the source code writing while keeping in mind previously defined requirements. The programming by itself assumes four stages

• Algorithm development

• Source code writing

• Compilation

• Testing and debugging

Stage 4. Testing

The testing phase includes the debugging process. All the code flaws missed during the development are detected here, documented, and passed back to the developers to fix.  

Stage 5. Deployment

When the program is finalized and has no critical issues – it is time to launch it for the end users.  

SDLC MODELS

Waterfall – is a cascade SDLC model, in which development process looks like the flow, moving step by step through the phases of analysis, projecting, realization, testing, implementation, and support. This SDLC model includes gradual execution of every stage completely. This process is strictly documented and predefined with features expected to every phase of this software development life cycle model.

ADVANTAGES  

Simple to use and understand

DISADVANTAGES

The software is ready only after the last stage is over

ADVANTAGES

Management simplicity thanks to its rigidity: every phase has a defined result and process review

DISADVANTAGES

High risks and uncertainty

Iterative SDLC Model

The Iterative SDLC model does not need the full list of requirements before the project starts. The development process may start with the requirements to the functional part, which can be expanded later.  

ADVANTAGES                                        

Some functions can be quickly be developed at the beginning of the development lifecycle

DISADVANTAGES

Iterative model requires more resources than the waterfall model

The paralleled development can be applied Constant management is required

Spiral SDLC Model

Spiral model – is SDLC model, which combines architecture and prototyping by stages. It is a combination of the Iterative and Waterfall SDLC models with the significant accent on the risk analysis.

Use the values in the range A7:A8 to extend the list of years to the range A9:A11. 3. Use AutoFill to fill the range A9:H11 with
jok3333 [9.3K]

Answer:

Question is incomplete and it needs a proper XL sheet image and more details. I have assumed and answered this question.

1. Use the values in the range A7:A8 to extend the list of years to the range A9:A11

Ans : <em>Use Ctrl + select A7: A8 and drag till A9: A11 : This will extend the list </em>

<em />

<em>2. </em>Use AutoFill to fill the range A9:H11 with the formatting from the range A7:H8.

Ans : Apply format immediately to the cells A9: H11 below with the help of Auto Fill Handle. Using Auto fill button we can able to a cell format to the cell bellow of active cell by just double clicking on the auto fill button.

3. In cell B8, create a formula without using a function that multiplies the value in cell B7 by the value in cell B6 and then adds the value in B7. Update the cell reference to cell B6, from a relative reference to a mixed reference by making an absolute reference to row 

Ans : =($B7*$B6)+$B7

4. Copy the formula from cell B8 to the range B9:B11 and then copy the formulas from the range B8:B11 to the range C8:H11.

Ans:

1. Select the cell B8 that contains which has formula to be copied

2. Click inside the formula bar to activate it and select the entire formula by using mouse and keyboard.

3. Copy the selected formula and press Esc to deactivate the formula bar.

4. Select the cell  B9 : B11 in which you want the copy of the formula to appear.

5. Most range names refer to absolute cell references. This means that when you copy a formula that uses a range name, the copied formula will use the same range name as the original.

6. Paste the formula by using references.

7. Repeat the steps of 1 to 6 for B8:B11 for range C8:H11.

5. Switch to the Cost Estimates worksheet. In cell A9, create a formula using the AVERAGE function that calculates the average of the values in the range A5:A7, then copy your formula to cell D9.

Ans : =AVERAGE(A5:A7) and Copy it to D9 using answer given in 4.
