Theory answers

(1a)
report in a database is the report created from a culmination of queried data visualized for the purposes of analysis, data discovery, and decision-making. In other words database reports can be created through traditional BI platforms and embedded BI platforms through front-end calls to a backend database.

(1b)
(i)Database reporting tools allow you to access any database and create reports based upon the stored data.

(ii)Relational databases store data in tabular relations. A database reporting tool typically queries relational databases using SQL over a JDBC or ODBC connection.

(iii)Database reporting on NoSQL big data sources relies on a customized SQL connector, ETL solution, or another native way at accessing data.

(iv)With Logi Report, you have the flexibility to embed reports, dashboards, and visualizations created from any data source.

(1c)
(i) Click File > Print.

(ii) To preview each page, click the forward and backward arrows at the bottom of the page. If the text is too small to read, use the zoom slider at the bottom of the page to enlarge it.

(iii) Choose the number of copies, and any other options you want, and click the Print button.

*2a*

First, convert AB116 into decimal, by using above steps:

= AB116
= A × 162B × 1611 × 160
= 273710

Now, we have to convert 273710 to octal

2737 / 8 = 342 with remainder 1
342 / 8 = 42 with remainder 6
42 / 8 = 5 with remainder 2
5 / 8 = 0 with remainder 5
Then just write down the remainders in the reverse order to get the answer, The hexadecimal number AB1 converted to octal is therefore equal to :

5261

*2b*
Decimal equivalent of “1” = 1 × 3^1 = 3
Decimal equivalent of “1” = 1 × 3^2 = 9
Decimal equivalent of “0” = 0 × 3^3 = 0
Decimal equivalent of “1” = 1 × 3^4 = 81
Decimal equivalent of “1” = 1 × 3^5 = 243
Decimal equivalent of “110111” = 243810931
110111 = 337

Now we will convert the fractional part 0.101 to decimal form (Don’t forget that we start from tenths palce to so on..):

Decimal equivalent of “1” = 1 × 3^-1 = 0.33333333333333
Decimal equivalent of “0” = 0 × 3^-2 = 0
Decimal equivalent of “1” = 1 × 3^-3 = 0.037037037037037
Decimal equivalent of “0.101” = 0.3333333333333300.037037037037037
0.101 = 0.37037037037037

Here is the final answer, The ternary number 110111.101 converted to decimal is therefore equal to:
= 110111.1013
= 33710 + 0.3703703703703710
= 337.3703703703703710

*2c*

First, convert 5078 into decimal, by using above steps:

= 5078
= 5 × 820 × 817 × 80
= 32710

Now, we have to convert 32710 to binary

327 / 2 = 163 with remainder 1
163 / 2 = 81 with remainder 1
81 / 2 = 40 with remainder 1
40 / 2 = 20 with remainder 0
20 / 2 = 10 with remainder 0
10 / 2 = 5 with remainder 0
5 / 2 = 2 with remainder 1
2 / 2 = 1 with remainder 0
1 / 2 = 0 with remainder 1
*1010001112*

The questions and answers above are not from the WAEC Computer Studies Objective. Go over them and you’ll be ready to ace your WAEC 2022 Computer Studies exam. Computer Science Paper 1 (Objective) and Paper 2 (Essay) can be found here.

How to to WAEC Computer studies examination

Every WAEC candidate wants to pass. No body wants to embark on exam second journey and that is you need to read this in order to pass.

Concentrate on your studies

Everyone understands that hard work leads to success. Make sure to read the West Africa Examination Council-recommended computer science textbooks (WAEC).

This will enable you to examine the majority of the questions that you will encounter on the day of the WAEC Computer examination.

Let me emphasize unequivocally that questions are derived from textbooks suggested by WAEC, not from heaven.

Go over past WAEC Computer Studies questions.

In order to create new questions, WAEC frequently selects questions from prior years. Past WAEC Computer Studies questions might help you understand how WAEC Computer questions are constructed.

Stop wasting time and start preparing for WAEC 2022. After you’ve obtained your textbooks and practice questions, it’s time to start reading. You will do well in WAEC 2022 Computer Studies if you start reading and practicing early.

SEE ALSO: WAEC Syllabus For Computer Studies 

Try to understand and solve every example and exercise in your textbooks.

Secondary school students have an undesirable habit of skipping exercises and even examples while studying textbooks.

They were so enamored with notebooks that they asked, “Can I read my Computer Studies notebook and pass WAEC 2022?” Don’t be afraid to try exercises; they’re there to assist you. Face it and conquer it!

I have extra examination tricks for you, Read it and get ready to make your papers.
