**For what purpose are computers used in the field of animation?**
Answer:
To create 2D and 3D moving images (CGI - Computer-Generated Imagery)
** Computers are fundamental to modern animation, used for modeling, rendering, and composing scenes to create animated films, TV shows, and video games.
132
**What type of computer acts as a central repository of data and programs for connected clients?**
Answer:
Server
** A server is a computer that provides data, services, or programs to other computers, known as clients, over a network. In a client-server model, the server is the central computer that manages resources for the clients.
133
**What does the 'E' in E-banking stand for?**
Answer:
Electronic
** E-banking, or Electronic Banking, refers to all forms of banking services and transactions that are conducted through electronic means, such as the internet, mobile phones, or ATMs.
134
What term is related to the concept of input data affecting the output in a computer system?
Answer:
Accuracy
The GIGO principle, short for "Garbage In, Garbage Out," is a fundamental concept in computing. It emphasizes that the quality and accuracy of the output produced by a computer system are directly dependent on the quality and accuracy of the data inputted into it. Therefore, 'Accuracy' is the term that best represents this relationship.
135
**In banking, what does EFT stand for?**
Answer:
Electronic Funds Transfer
** EFT is the electronic transfer of money from one bank account to another, either within a single financial institution or across multiple institutions, through computer-based systems.
136
**A collection of 8 bits is called a:**
Answer:
Byte
** The byte is a standard unit of digital information in computing and telecommunications. It is the basic addressable element in many computer architectures.
137
The characteristic that allows a computer to be used in fields as diverse as entertainment, education, and medicine is:
Answer:
Versatility
** The wide range of applications for computers is a direct result of their versatility. The same hardware can be programmed to perform vastly different functions, making computers a universal tool.
138
Approximately how many bytes are in a kilobyte (KB)?
Answer:
1,000
** In the decimal system (used for storage capacity), a kilobyte is 1,000 bytes. In the binary system (used for memory), a kilobyte (or more accurately, a kibibyte) is 1,024 (2^10) bytes. For general purposes, 1,000 is the common approximation.
139
**Minicomputers are also known as:**
Answer:
Mid-range computers
** Minicomputers, or mid-range computers, are multi-user computers which are more powerful than microcomputers but less powerful than mainframe computers. They were commonly used in the 1960s and 70s before high-end microcomputers became prevalent.
140
**A quantum computer, a new and emerging type of computer, is based on the principles of:**
Answer:
Quantum mechanics
** Quantum computers leverage quantum-mechanical phenomena, such as superposition and entanglement, to perform calculations. They have the potential to solve certain problems much faster than classical computers.
