Computer Review and Exam

What must occur before patterns can be identified in data?

• Computational tools must process the data in iterative ways.

• Algorithms need to be written for the patterns.

• Abstracting out the details in the data must occur.

• The data must be encrypted.

Why should procedures be used?

• They case the workload on the processors.

• They facilitate the storage of data on hard drives

• They make writing and maintaining programs easier through reuse of code.

• They control the flow of input and output data.

How should large datasets be analyzed?

• Using information filtering and search tools because they are efficient.

• Using frequency analysis tools so patterns stand out.

• Using exponential tools for faster analysis.

• Using linear tools to see patterns as they develop.

What can help with identifying and correcting program errors?

• Revisiting requirements

• Collaboration

• Clustering requirements and test

• Consolidating testing

How can financial transactions safely occur on the Internet?

• Through the use of symmetric keys

• Through certificates issued by Certificate Authorities (CAs) that validate the keys used

• Through the use of double authentication methods

• Through the use of frequency analysis

What is the definition of bandwidth?

• The frequency that data can be transmitted across the Internet

• The speed that data can be sent through the Internet

• The amount of data that can transmitted in a fixed amount of time

• The delay between the request and the receipt of information on the Internet

Which type of loop is most effective to iterate over a list?

• Continuous

• While

• For Each

• Do

What is one way to help ensure the correctness of algorithms?

• By testing with small sets of expected data

• Through the reuse of existing correct algorithms to build new algorithms

• Through documenting the functionality of the algorithm

• Through the use of heuristic algorithms

How has the sharing of information globally with experts impacted the medical field?

• Diagnosis and consultations can be done by non-local experts

• There's been an increase in the sales of hardware needed to create the Internet to enable the sharing of data.

• Privacy laws have prevented the sharing of patient data on the Internet. It can be discussed online after sending the data using a delivery service.

• Social media sharing has increased the general public's knowledge of disease outbreaks.

How is collaboration useful in analyzing datasets?

• The multiple viewpoints can provide several outcomes for the data.

• Applying differing experience and skills provides better analysis and insight

• The analysis can be divided among several people, speeding up the analysis

• Having multiple leaders helps the group form alliances based on interest.
