Answer Details
The set of instructions written by computer experts to solve a specific task of the user is called application software. Application software is a type of computer software that is designed to perform specific tasks, such as word processing, spreadsheet management, and media editing. It is created by developers to meet the needs of users, and it is installed onto a computer to help the user perform a certain task. Examples of application software include Microsoft Word, Excel, and Adobe Photoshop. Operating systems, system software, and utility software are different types of software. The operating system is the primary software that manages all of the hardware and software resources of a computer, while system software includes programs that help manage and maintain the computer, such as device drivers, security software, and system utilities. Utility software refers to programs that are designed to perform specific tasks, such as disk cleanup, backup, and optimization.
Question 2 Report
Which of the file organization methods can be accessed both randomly and sequentially?
Answer Details
The file organization method that can be accessed both randomly and sequentially is the Indexed Sequential Files. Indexed Sequential Files use an index to organize data records, allowing for both sequential and random access. The records are stored in sequence based on a primary key field, and the index keeps track of the location of each record. This allows for sequential access by reading the records in order, or random access by searching for a specific record based on its key value. For example, imagine a library catalog that is organized using an Indexed Sequential File. The books in the library are stored in order by their call numbers (i.e., the primary key field), and an index is kept that maps each call number to its location in the library. A patron could browse the catalog sequentially by looking at each book in order, or they could search for a specific book by using the index to find its location. Overall, Indexed Sequential Files provide the flexibility of both sequential and random access, making them a popular choice for applications that require both types of access.
Question 5 Report
In BCD encoding system, 25, will be represented as?
Answer Details
In BCD (Binary Coded Decimal) encoding system, 25 will be represented as 00100101. BCD is a system that represents each digit of a decimal number with its equivalent binary code. In BCD, each decimal digit is represented by a four-bit binary code. Therefore, the decimal number 25 is represented in BCD as follows: The binary representation of 2 is 0010, and the binary representation of 5 is 0101. So, combining the binary codes for both digits, we get 0010 0101, which is equivalent to the decimal number 25 in BCD representation. Therefore, the correct option is 00100101.
Question 7 Report
The disk operating system will label three hard drives as?
Answer Details
The labeling of hard drives depends on the specific operating system being used. However, it is common for disk operating systems to label hard drives as letters starting from "C". This is because the first two letters, "A" and "B", are reserved for floppy drives. So, the most common labeling of hard drives is "C, D, and E".
Question 9 Report

Answer Details
The suite of software that controls and manages the basic operation of a computer is called system software. It includes programs that provide essential functionalities like managing hardware resources, running other software applications, and providing a user interface for interacting with the computer. Examples of system software include operating systems like Windows, macOS, and Linux, device drivers, system utilities, and firmware. System software is different from application software, which is designed to perform specific tasks like word processing, spreadsheet management, or video editing.
Question 12 Report
Three major types of language translators are?
Answer Details
The three major types of language translators are: Assembler, Compiler, and Interpreter. An Assembler is a translator that converts assembly language code, which is a low-level programming language, into machine language code that a computer can understand and execute. Assembly language is specific to a particular computer architecture, so an assembler is also specific to that architecture. A Compiler is a translator that converts high-level programming language code, which is more human-readable, into machine language code that a computer can understand and execute. The process of compilation involves several stages, including lexical analysis, syntax analysis, semantic analysis, code generation, and optimization. Once compiled, the resulting machine code can be run repeatedly without needing to recompile the source code. An Interpreter is a translator that works by executing high-level programming language code directly, without the need to first compile it into machine language code. Interpreters translate code line-by-line, executing each line immediately before moving on to the next one. This process is slower than compilation, but it allows for greater flexibility and interactivity during development, as changes to the source code can be tested immediately without needing to recompile.
Question 13 Report

Question 19 Report
Effects of file insecurity include the following except?
Answer Details
The effects of file insecurity include virus infection, file corruption, and data loss. However, encrypted data is not an effect of file insecurity. When files are insecure, they can be easily infected by viruses and malware, which can cause harm to the computer and compromise sensitive data. File corruption can occur due to various reasons such as hardware failure, software errors, or virus attacks. This can lead to files becoming unreadable or unusable, which can cause significant inconvenience and loss of important information. Data loss is also a common effect of file insecurity, which can occur due to accidental deletion, system failure, or hardware damage. Encrypted data, on the other hand, is a security measure that is used to protect files and data from unauthorized access. It is not an effect of file insecurity, but rather a way to prevent file insecurity from happening. Encryption involves converting the original data into a code that is unreadable without a specific decryption key. This helps to ensure that sensitive data is kept safe and secure, even if the files themselves are compromised.

The scanner and the floppy disk are?
Answer Details
A scanner and a floppy disk are respectively an input device and a storage device. A scanner is a device used to convert a physical document or image into a digital format. It works by using a light source to capture an image and then digitize it. This means that it takes information from the physical world and converts it into a form that a computer can understand and process, making it an input device. On the other hand, a floppy disk is a type of removable storage device used to store and transfer data. It works by using magnetic storage to store data on a disk that can be easily removed and used in another computer. This means that it takes information from the computer and stores it in a physical form that can be accessed later, making it a storage device.
Question 36 Report
Data transfer can be initiated through the following media except?
Figure 1 28. The topology
Answer Details
Data transfer cannot be initiated through trunking pipe. Trunking pipes are used to protect and route cables, but they are not capable of initiating data transfer themselves. On the other hand, coaxial cable, fibre cable, and twisted pair cable are all examples of media that can be used to initiate data transfer. Coaxial cable uses a central conductor surrounded by insulation and a grounded shield to transmit signals, while fibre cable uses thin strands of glass or plastic to transmit light signals, and twisted pair cable uses pairs of copper wires twisted together to transmit electrical signals. Each of these media has its own advantages and disadvantages, and the choice of which one to use will depend on factors such as distance, bandwidth requirements, and cost.
Question 37 Report
The following symbols are used in flowcharting except the?
Answer Details
The answer is "close symbol." Flowcharts are diagrams that are used to represent the flow of a process or system. They use different symbols to represent different elements of the process, such as starting points, decision points, and actions. Terminal symbols, also known as start/end symbols, are used to indicate the beginning or end of a process or flowchart. Process symbols are used to represent actions or steps in the process, while input/output symbols are used to represent data inputs or outputs. However, there is no such thing as a "close symbol" in flowcharting. There are, however, symbols such as the decision symbol, which is used to indicate a point in the process where a decision needs to be made based on a condition or set of conditions. In summary, the correct answer is "close symbol" because there is no such symbol used in flowcharting.

However, it is important to note that technology is constantly evolving, so it's possible for there to be newer computers that are even faster and smaller than current ones.
Question 40 Report
A Collection of software that allows the computer to operate is called?
Answer Details
The collection of software that allows a computer to operate is called an Operating System (OS). An Operating System is a software that manages computer hardware and provides common services for computer programs. It acts as an interface between the hardware components of the computer and the applications that run on it. The operating system is responsible for managing resources such as memory, CPU time, and input/output operations. It also provides a user interface that enables users to interact with the computer and run applications. General-purpose software and specific software are not appropriate terms to describe the collection of software that allows a computer to operate. General-purpose software refers to software that can perform a variety of functions, such as word processing, spreadsheet management, and email communication. Specific software, on the other hand, is designed to perform a particular task, such as graphic design or accounting. Utility software, on the other hand, refers to software that performs specific tasks to maintain the performance and functionality of a computer system, such as virus scanners, disk defragmenters, and backup tools. However, utility software alone cannot allow a computer to operate; it needs an operating system to function. Therefore, the collection of software that allows a computer to operate is called an Operating System.

Data that is copied from an application is store the?
Answer Details
Data that is copied from an application is stored in the clipboard. The clipboard is a temporary storage location that allows you to copy and paste information between different applications or within the same application. When you copy data, it is stored in the clipboard, which is a type of memory that holds the data until you paste it elsewhere. Once you paste the data, it is removed from the clipboard, and the clipboard is ready to store new data. Therefore, the clipboard acts as a buffer that allows you to move information from one place to another, making it a useful tool for working with multiple applications or files.

Question 49 Report
The output of a NAND gate is 1 when?
Answer Details
A NAND gate is a logic gate that produces an output of 0 only when all its inputs are 1. In all other cases, the output is 1. So, if any of the inputs is 0, the output will be 1. If all the inputs are 1, the output will be 0. To put it another way, the NAND gate behaves like an "inverted AND" gate. It produces an output of 1 when any of the inputs is 0, and only produces an output of 0 when all the inputs are 1. This behavior makes the NAND gate a very useful building block in digital circuits, as it can be used to implement any other logical function.

(a) Explain the following terms: (i) storage device; (ii) virtual memory.
(b) Two storage devices have capacities 2KB and 2MB respectively. (i) Calculate the number of bits that each of 2KB and 2MB can hold. 2 KB: 2 MB
(i) Putting the two storage together, calculate the total capacity in bytes.
(a)
-
(i) A storage device is a physical device used to store digital information such as data, documents, pictures, videos, or software programs. Storage devices can be classified into primary storage devices and secondary storage devices. Primary storage devices include Random Access Memory (RAM) and cache memory, while secondary storage devices include Hard Disk Drives (HDDs), Solid State Drives (SSDs), USB flash drives, CD/DVDs, and memory cards.
-
(ii) Virtual memory is a technique used by a computer's operating system to expand the available memory by using the hard disk as temporary storage. When a computer runs out of RAM, it moves some of the less frequently used data from RAM to the hard disk, freeing up space in RAM for more immediate data. The operating system manages this process automatically, and the user is generally unaware of it.
(b)
-
(i) 2KB can hold 2,048 bits (1 byte = 8 bits, therefore 2KB = 2,048 bytes x 8 bits/byte = 16,384 bits) while 2MB can hold 16,777,216 bits (2MB = 2,048,000 bytes x 8 bits/byte = 16,777,216 bits).
-
(ii) To calculate the total capacity in bytes when the two storage devices are put together, we simply add the capacities of the two devices. Thus, the total capacity is 2KB + 2MB, which equals 2,048 bytes + 2,048,000 bytes = 2,050,048 bytes.

(d) Insert your full name and index number as a label on the report.
(e) Save the report as rpt-Employee.
(f) Print your work and submit to the supervisor.
To create a table named "tbl-Employee" in a database application package, you would need to use a database management system and write a SQL (Structured Query Language) script to create the table and specify the fields. The fields you need to include are: "Employee Name", "Department", "Assumption Date", "Address", and "Designation".
Here's an example of the SQL script to create the table:
CREATE TABLE tbl-Employee (
EmployeeName varchar(50),
Department varchar(50),
AssumptionDate date,
Address varchar(100),
Designation varchar(50)
);
Next, you can insert the data into the table using the following SQL script:
INSERT INTO tbl-Employee (EmployeeName, Department, AssumptionDate, Address, Designation)
VALUES
('Kate Willikie', 'General Office', '03/08/18', '3 Lagos Crescent', 'Secretary'),
('James Elliot', 'Security', '27/11/10', '2 Cocoa House Villa.', 'CSO'),
('Paul Akinson', 'Admin', '03/11/12', '12 Millo Avenue', 'HRM'),
('Abdul Kaduna', 'Registry', '05/06/16', '2 Park Lane Rd', 'Clerk'),
('David Madu', 'Management', '22/03/94', '34 Lakeside', 'MD');
To sort the data by the "Assumption Date" field from oldest to newest, you can use the following SQL script:
SELECT * FROM tbl-Employee
ORDER BY AssumptionDate ASC;
For the report, you can use a reporting tool or generate a SQL script to format the data into a tabular, landscape report. You can add your full name and index number as a label on the report by including it as a header or footer in the report.
Finally, you can save the report as "rpt-Employee" and print it for submission to your supervisor.
Answer Details
To create a table named "tbl-Employee" in a database application package, you would need to use a database management system and write a SQL (Structured Query Language) script to create the table and specify the fields. The fields you need to include are: "Employee Name", "Department", "Assumption Date", "Address", and "Designation".
Here's an example of the SQL script to create the table:
CREATE TABLE tbl-Employee (
EmployeeName varchar(50),
Department varchar(50),
AssumptionDate date,
Address varchar(100),
Designation varchar(50)
);
Next, you can insert the data into the table using the following SQL script:
INSERT INTO tbl-Employee (EmployeeName, Department, AssumptionDate, Address, Designation)
VALUES
('Kate Willikie', 'General Office', '03/08/18', '3 Lagos Crescent', 'Secretary'),
('James Elliot', 'Security', '27/11/10', '2 Cocoa House Villa.', 'CSO'),
('Paul Akinson', 'Admin', '03/11/12', '12 Millo Avenue', 'HRM'),
('Abdul Kaduna', 'Registry', '05/06/16', '2 Park Lane Rd', 'Clerk'),
('David Madu', 'Management', '22/03/94', '34 Lakeside', 'MD');
To sort the data by the "Assumption Date" field from oldest to newest, you can use the following SQL script:
SELECT * FROM tbl-Employee
ORDER BY AssumptionDate ASC;
For the report, you can use a reporting tool or generate a SQL script to format the data into a tabular, landscape report. You can add your full name and index number as a label on the report by including it as a header or footer in the report.
Finally, you can save the report as "rpt-Employee" and print it for submission to your supervisor.
