NEW QUESTION # 32
Which three are the advantages ofDistributed Database? (Choosethree)
- A. Easy to scale
- B. Increase Availability
- C. Improved Performance
- D. Easier Expansion
Answer: B,C,D
Explanation:
Distributed databases provide several advantages over centralized databases, including improved scalability, availability, performance, flexibility, fault tolerance, and security1. Here are some of the advantages of distributed databases:
Increased availability: Distributed databases can tolerate failures of individual nodes or sites without affecting the overall system functionality. Users can access data from other sites if their local site is down or unreachable. Data replication and backup mechanisms can also enhance data availability and recovery2.
Easier expansion: Distributed databases can be scaled horizontally by adding more nodes to the network. This allows for increased capacity and performance as data and user demand grow. Adding new sites or units to the distributed system does not require significant efforts or disruption in the existing functions2.
Improved performance: Distributed databases can offer faster response and lower communication costs by locating data near the users who normally use that data. Distributed query processing and transaction management can also optimize the use of network and computing resources. Furthermore, distributed databases can exploit the parallelism of multiple nodes to execute operations concurrently13.

NEW QUESTION # 33
Which methodology is basedon the notation of functions;programs consist of modules to meet functional requirements?
- A. Transnational Approach
- B. Structured Approach
- C. Object-Oriented Approach
- D. Model Approach
Answer: B
Explanation:
The Structured Approach is a methodology that is based on the notation of functions; programs consist of modules to meet functional requirements. The Structured Approach focuses on the processes involved in a software system, modeling them as a series of connected steps. It follows a top-down approach, breaking down complex systems into smaller, simpler parts that can be more easily understood. It also focuses on the data that a software system manipulates, modeling it as data flows between processes. It emphasizes the functional decomposition of a software system into smaller, independent functions12.

NEW QUESTION # 34
Which feature supports more than one processor?
- A. Multiprocessing
- B. Multitasking
- C. Multithreading
- D. Multiswitching
Answer: A
Explanation:
Multiprocessing is a feature that supports more than one processor in a computer system. It allows multiple processes to run concurrently on multiple CPUs (or cores), thus increasing the performance and throughput of the system12. Multiprocessing can be achieved by using either multiple physical processors or a single processor with multiple cores3. Multiprocessing can also be classified into symmetric multiprocessing (SMP) and asymmetric multiprocessing (AMP), depending on how the processors are coordinated and share resources4.
Multiprocessing is different from other features such as multiprogramming, multitasking, and multithreading. Multiprogramming is the ability of an operating system to keep multiple programs in the main memory at the same time, ready for execution5. Multitasking is the ability of an operating system to switch between multiple tasks (applications) on a single CPU, giving the illusion of parallelism6. Multithreading is the ability of an application to create multiple threads of execution within a single task, sharing the same memory space and resources7. These features aim to maximize the utilization of CPU and memory, but they do not require more than oneprocessor.

NEW QUESTION # 35
Which two designs are considered to design a system? (Choosetwo)
- A. Functional Design
- B. Object-Oriented Design
- C. Organizational Design
- D. Structured design
Answer: B,D
Explanation:
Structured design and object-oriented design are two common approaches to design a system. Structured design is a method of breaking down a system into smaller and simpler modules, which can be independently created and tested. Structured design follows a top-down approach, where the system is divided into sub-systems, and then into modules, until the desired level of detail is reached. Structured design is suitable for systems that have well-defined inputs and outputs, and a clear hierarchy of functions. Object-oriented design is a method of modeling a system as a collection of objects, which have attributes and behaviors. Object-oriented design follows a bottom-up approach, where the system is built from reusable and interchangeable components, called classes. Object-oriented design is suitable for systems that have complex interactions, dynamic behavior, and multiple inheritance. Functional design and organizational design are not considered to design a system, but rather to describe the system's purpose and structure. Functional design is a process of defining the functions and processes that the system performs, and how they relate to each other. Functional design focuses on the what and why of the system, rather than the how. Organizational design is a process of defining the roles and responsibilities of the people and units involved in the system, and how they communicate and coordinate with each other. Organizational design focuses on the who and where of the system, rather than the how.

NEW QUESTION # 36
Which term describes dormant code added to software andtriggered at a predetermined time or by a predetermined event?
- A. Virus
- B. Keylogger
- C. Spam
- D. Logic Bomb
Answer: D
Explanation:
A logic bomb is a type of malicious code that is inserted into a software program and remains dormant until a specific condition or event occurs, such as a certain date, time, or user action. When the condition is met, the logic bomb activates and executes its harmful payload, which can range from deleting or corrupting data, to displaying unwanted messages, to crashing the system. Logic bombs are often used by disgruntled employees or hackers to sabotage an organization's IT infrastructure or to extort money or information. Logic bombs are different from keyloggers, spam, and viruses, which are explained below:
A keylogger is a software or hardware device that records every keystroke made by a user on a computer or mobile device, usually for the purpose of stealing passwords, personal information, or other sensitive data. Keyloggers can be installed by hackers through phishing, trojan viruses, or physical access to the device. Keyloggers do not wait for a specific condition to activate, but rather run continuously in the background and transmit the captured data to a remote server or storage device.
Spam is any kind of unwanted, unsolicited, or irrelevant digital communication that is sent or posted to a large number of recipients or places, typically for the purposes of advertising, phishing, spreading malware, or disrupting normal operations. Spam can be delivered via email,text message, phone call, or social media. Spam does not contain hidden code that executes a harmful action, but rather relies on the user's response or interaction to achieve its goal, such as clicking a link, opening an attachment, or providing personal information.
A virus is a type of malware that infects a computer or mobile device by attaching itself to another program or file and replicating itself when the host program or file is executed. A virus can have various harmful effects, such as deleting or modifying data, consuming system resources, displaying unwanted messages, or opening backdoors for hackers. A virus can spread from one device to another through networks, removable media, or email attachments. A virus does not require a specific condition to activate, but rather runs whenever the infected program or file is executed.

NEW QUESTION # 42
Information derived from processing transactionreduces uncertainty about a firm's order backlog or financial position.
- A. False
- B. True
Answer: B
Explanation:
Information derived from processing transaction reduces uncertainty about a firm's order backlog or financial position because it provides a quantitative and forward-looking measure of demand. Order backlog is the amount of orders that a firm has received but not yet fulfilled. It reflects the expected future revenue and cash flows of the firm, as well as its ability to meet customer needs and expectations. Order backlog can also indicate the competitive position and market share of the firm, as well as its operational efficiency and capacity utilization. Therefore, disclosing order backlog can help stakeholders such as investors, analysts, managers, and regulators to assess the firm's performance and prospects more accurately and reliably.
