____________ is a device that works with discrete-distinct data such as 0 or 1.
Correct Answer
A. Digital Device
Explanation
A digital device is the correct answer because it is specifically designed to work with discrete data, which is represented by binary digits (0 or 1). Unlike analog devices that work with continuous data, digital devices process and store information in a binary format, allowing for precise and accurate calculations. Input and output devices, on the other hand, refer to the means by which data is entered into or displayed by a device, and do not necessarily imply the use of digital technology.

From the following , identify which are the capabilities of Function-based IntegratedSystem.1. Intended for the exclusive support of a specific application area.2. Share a common set of database files.3. Only one database file implies 0% redundancy and 100% data integrity4.Database files easily become different if one is updated are the others are not.
Correct Answer
D. 1 and 4 only
Explanation
The Function-based Integrated System is intended for the exclusive support of a specific application area, which is mentioned in statement 1. This means that it is designed to cater to the specific needs and requirements of that particular application area. Additionally, statement 4 states that the database files easily become different if one is updated and the others are not. This implies that there can be differences in the data stored in the database files, highlighting the lack of data integrity. Therefore, the correct answer is 1 and 4 only.

____________is a computer program that searches for specific words and returns a list of documents in which they were found, especially a commercial Internet service.
Correct Answer
D. Search Engine
Explanation
A search engine is a computer program that searches for specific words and returns a list of documents in which they were found. It is commonly used on the internet as a commercial service, with popular examples being Google and Yahoo. These search engines allow users to input their search queries in a search textbox, and then the engine scans its database to find relevant documents that contain the specified words. The search engine then presents the user with a list of results that match their query, making it easier to find information on the internet.

___________________ is a process wherein all data processing operations and calculations are executed bythe central computer.
Correct Answer
C. Distributed Data Processing
Explanation
Distributed Data Processing refers to a process where all data processing operations and calculations are executed by multiple computers or servers instead of a central computer. This allows for better scalability, fault tolerance, and improved performance as the workload is distributed across multiple machines. This approach is commonly used in large-scale systems where a single central computer may not be able to handle the processing requirements efficiently.
9.
Users in ________________ are allowed to request information from a database.
Correct Answer
B. Query Language
Explanation
In this specialized language, users are allowed to request information from a database. This language is known as a query language. It is specifically designed to interact with databases and retrieve data based on specific criteria or conditions. Users can use query language commands to search, filter, and extract information from the database. Therefore, the correct answer is Query Language.
10.
_______________ is a system of instructions and data directly executed by a computer's central processing unit.
Correct Answer
C. Machine Language
Explanation
Machine language is the correct answer because it refers to the set of instructions and data that can be directly executed by a computer's central processing unit. It consists of binary code that represents specific operations and addresses in the computer's memory. This low-level programming language is specific to the computer's hardware and is often used by assembly language programmers to write software that can directly control the computer's hardware components. It is the closest representation of how a computer actually understands and executes instructions.

_______________________ is a pioneer in implementing von Neumann’s Architecture, the key to which theCentral Processing Unit, which allowed all computer functions to be coordinated though a single source.
Correct Answer
A. EDVAC
Explanation
EDVAC is the correct answer because it was one of the first computers to implement von Neumann's architecture. This architecture is characterized by having a central processing unit (CPU) that coordinates all computer functions through a single source. Therefore, EDVAC's implementation of von Neumann's architecture allowed for the coordination of all computer functions through the CPU, making it the correct answer.
12.
_________________ provides the instructions needed to load the core parts into memory when system boots.
Correct Answer
C. Bootstrap Program
Explanation
The bootstrap program is responsible for loading the core parts of the operating system into memory when the system boots up. It provides the necessary instructions for the system to initialize and start running. Without the bootstrap program, the system would not know how to properly load and execute the kernel and other essential components.
13.
________________ is a programming paradigm based on the concepts that computers are programmed in the same way as how humans think.
Correct Answer
B. Neural Network
Explanation
Neural Network is the correct answer because it is a programming paradigm that is based on the concepts of how humans think. It is inspired by the functioning of the human brain and consists of interconnected nodes or artificial neurons that work together to process and analyze data. This approach allows computers to learn and make decisions in a similar way to humans, making it an effective tool for tasks such as pattern recognition, data classification, and prediction.

_______________ is a type of computer memory chip that allows instructions and data to be stored, changed and retrieved by the user.
Correct Answer
C. Random Access Memory
Explanation
Random Access Memory (RAM) is a type of computer memory chip that allows instructions and data to be stored, changed, and retrieved by the user. Unlike Read Only Memory (ROM) which is non-volatile and cannot be modified, RAM is volatile and can be read from and written to. It provides temporary storage for data that is actively being used by the computer's operating system and applications. When the computer is turned off or restarted, the data stored in RAM is lost. Virtual Memory and Programmable Read Only Memory are not accurate descriptions for this type of memory.
17.
_______________ is the manipulation of "on" and "off" signals to perform complex tasks.
Correct Answer
C. Digital Electronics
Explanation
Digital Electronics refers to the field of electronics that deals with the manipulation and control of digital signals, which are represented by discrete values of "on" and "off". These signals are used to perform complex tasks and operations in various electronic devices and systems. Unlike analog electronics, which deals with continuous signals, digital electronics focuses on discrete and binary representations of data. Therefore, the given answer accurately describes the concept of digital electronics and its application in performing complex tasks through the manipulation of "on" and "off" signals.

What is the equivalent decimal value of AE103 base-16?
Correct Answer
C. 712963
Explanation
The correct answer is 712963 because AE103 in base-16 is equal to 712963 in base-10. In hexadecimal (base-16), each digit represents a power of 16. A is equivalent to 10, E is equivalent to 14, and 1 is equivalent to 1. So, AE103 can be calculated as (10 * 16^4) + (14 * 16^3) + (1 * 16^2) + (0 * 16^1) + (3 * 16^0) = 712963.
