Computer-based examinations (CBEs) offer several advantages over traditional paper-and-pencil tests. A significant benefit, and often a primary reason for their adoption, is the ability to automate the scoring process. This automation allows for instant results and immediate feedback to be provided to the test-taker, which can be highly beneficial for learning and understanding performance. Option A is incorrect because CBEs are often administered in dedicated computer labs or with provided devices, not necessarily requiring each student to own a personal computer. Option C is incorrect; like any technology, CBEs are susceptible to technical glitches, though robust systems aim to minimize them. Option D is incorrect as CBEs inherently require electrical power to operate computers and servers.

Computer-Based Testing (CBT) refers to a modern assessment methodology where candidates use a computer to take an exam. This involves questions being displayed on a screen and responses being entered digitally, rather than on paper. Key characteristics of CBT include electronic recording of responses, often automated scoring, and the potential for a wide variety of interactive question types (e.g., drag-and-drop, simulations). This method enhances efficiency, security, and provides immediate or faster feedback compared to traditional paper-based exams. Option A describes traditional paper-based testing. Option C describes an oral exam. Option D is incorrect as CBT inherently involves electronic devices.

Optical Mark Recognition (OMR) is the technology specifically designed for detecting the presence or absence of marks in predefined positions on a paper document, such as bubbles or shaded areas on an answer sheet. This allows for rapid and automated grading of multiple-choice questions in standardized tests.

* Magnetic Ink Character Recognition (MICR) is used primarily by the banking industry for processing checks, reading specially formatted characters printed with magnetic ink.
* Optical Character Recognition (OCR) converts images of typewritten or handwritten text into machine-encoded text, which is different from detecting shaded bubbles.
* Radio-Frequency Identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects, commonly used for inventory management or access control, not for grading test papers.

In computer science, an algorithm is fundamentally a well-defined computational procedure that takes some value or set of values as input and produces some value or set of values as output. More simply, it's a step-by-step method or a set of rules for solving a problem or accomplishing a task. Option (a) describes hardware. Option (c) describes a type of application software. Option (d) describes test data, not an algorithm.

A test authoring tool is a specialized software that provides functionalities for educators and examiners to create, manage, and deploy online tests and quizzes. These tools typically include features for designing various question types (e.g., multiple-choice, true/false, fill-in-the-blank), organizing and selecting questions from a question bank, setting test parameters (such as time limits, scoring, and question randomization), and publishing the exam for students to take. OMR software is used for scanning and grading paper-based tests, plagiarism detection software identifies academic dishonesty, and a core banking system manages financial transactions, none of which directly facilitate the creation and deployment of online exams from a question bank.

Electronic Funds Transfer (EFT) is the correct answer. It is a comprehensive system that enables the electronic movement of money between financial institutions or accounts. Examples of EFT include direct deposit of paychecks, online bill payments, wire transfers, and automated teller machine (ATM) transactions.

Option A, Optical Mark Recognition (OMR), is a technology used to read human-marked data from documents, like surveys or tests, and is unrelated to financial transfers.

Option B, Electronic Commerce (E-commerce), refers to the buying and selling of goods and services, or transmitting funds or data, over an electronic network, primarily the internet. While EFT is a component that enables e-commerce, e-commerce itself is a broader concept of online business, not the specific system for funds transfer.

Option D, Core Banking System (CBS), is a centralized system used by banks to manage their main operations, such as account management, loan processing, and customer relationship management. While CBS facilitates EFT services, it is the underlying platform for all banking operations, not the specific term for electronic fund transfers.

Data storage units are organized hierarchically based on their capacity. Starting from the smallest common unit listed and moving to the largest:

* **Kilobyte (KB):** Approximately 1,024 bytes.
* **Megabyte (MB):** Approximately 1,024 Kilobytes (KB).
* **Gigabyte (GB):** Approximately 1,024 Megabytes (MB).
* **Terabyte (TB):** Approximately 1,024 Gigabytes (GB).

Therefore, a Terabyte (TB) represents the largest amount of data among the options provided, as 1 TB is roughly equivalent to 1,000 GB.

OMR stands for Optical Mark Recognition. It is a technology that detects the presence or absence of a mark in a designated area on a document, such as a bubble or checkbox. This technology is widely used in examinations to rapidly and accurately score multiple-choice answer sheets, surveys, and other forms where data is captured through human-filled marks. It automates the process of data entry and evaluation, significantly reducing the time and potential for error compared to manual methods.

A speed test will give you a good idea of your current throughput (download/upload speeds) and latency (ping), which are the two main indicators of connection performance.

A computer bus supports the fastest data rate for devices within a computer compared to external lines.
