What are the answers to the following multiple-choice questions on computer technology?

Here are the solutions to the questions:

1. Virtual reality creates simulated environments that can be experienced in three dimensions. It heavily relies on 3-D Technology to render these immersive worlds.

   $$\boxed{\text{B) 3-D Technology}}$$

2. EFT stands for Electronic Funds Transfer, which is the process of transferring money from one bank account to another electronically, often online.

   $$\boxed{\text{E) EFT}}$$

3. Computer modelling is the process of creating a mathematical or computational representation of a real-world system or process. This is often done through Simulation, where the model is run to observe its behavior over time.

   $$\boxed{\text{B) Simulation}}$$

4. Computers are important tools for Computer-Aided Learning (CAL), Computer-Aided Manufacturing (CAM), Computer-Aided Design (CAD), and Computer Algebra Systems (CAS). CT Scans (Computed Tomography Scans) are a medical imaging procedure that uses computers for data acquisition and processing, but the scan itself is a diagnostic procedure rather than a general field where computers are tools in the same category as the "Computer-Aided" applications.

   $$\boxed{\text{E) CT Scans}}$$

5. The Input Unit (e.g., keyboard, mouse, scanner) is responsible for receiving data from the user and converting it into a digital format that the computer's central processing unit can understand and process.

   $$\boxed{\text{C) Input Unit}}$$

6. The only language that a computer's central processing unit (CPU) can directly execute is machine code, which is represented in Binary Language (sequences of 0s and 1s).

   $$\boxed{\text{B) Binary Language}}$$

7. The smallest unit of data in a computer is a Bit, which is a binary digit (either 0 or 1).

   $$\boxed{\text{C) Bit}}$$

8. A nibble is a unit of data storage that consists of 4 bits.

   $$\boxed{\text{B) 4}}$$

9. In low-level programming or assembly language, IN or INP followed by a port number is a common format for an
