Which of the following is NOT a method used to resolve incompatiblility between platfoms?
- A.
Computers now use same platform
- B.
Programs use same file formates
- C.
Emulators allow one OS to run programs written for other OS
Correct Answer
A. Computers now use same platformExplanation
The given answer states that "computers now use the same platform" is NOT a method used to resolve incompatibility between platforms. This means that having computers use the same platform is not a solution to address compatibility issues between different platforms. Instead, other methods like using programs with the same file formats or using emulators to run programs written for different operating systems are suggested as possible solutions.Rate this question:

Which is an example of an analog computer?
- A.
Desktop computer
- B.
Electronic calculator
- C.
Thermometer
- D.
Computer network
Correct Answer
C. ThermometerExplanation
A thermometer is an example of an analog computer because it measures temperature using a physical quantity, such as the expansion of a liquid or the change in electrical resistance. Analog computers operate on continuous data and perform calculations through the manipulation of physical variables. In contrast, desktop computers, electronic calculators, and computer networks are examples of digital computers, which process data in discrete binary form.Rate this question:

What three colors are used to digitize images?
- A.
Black, white,green
- B.
Yellow, black, red
- C.
Blue, green, red
- D.
Red, blue, black
Correct Answer
C. Blue, green, redExplanation
The three colors used to digitize images are blue, green, and red. This is known as the RGB color model, where each pixel in an image is represented by a combination of these three primary colors. By varying the intensity of each color, a wide range of colors can be displayed on a digital screen or image.Rate this question:

Which language does NOT need Unicode to represent its character set?
- A.
Chinese
- B.
English
- C.
Greek
- D.
Hebrew
Correct Answer
B. EnglishExplanation
English does not need Unicode to represent its character set because it uses the ASCII character encoding system, which is a subset of Unicode. ASCII can represent all the characters used in the English language, including letters, numbers, and common punctuation marks. Unicode is necessary for languages that have a larger character set, such as Chinese, Greek, and Hebrew, which have thousands of unique characters that cannot be represented by ASCII alone.Rate this question:

Which input device can be used to input photos?
- A.
Graphics tablet
- B.
Mouse
- C.
Keyboard
- D.
Scanner
Correct Answer
D. ScannerExplanation
A scanner is an input device that can be used to input photos. It is designed to capture physical images and convert them into digital format, allowing users to store, edit, and manipulate the photos on a computer. Unlike a graphics tablet, mouse, or keyboard, which are primarily used for inputting text or creating digital drawings, a scanner specifically specializes in capturing and digitizing physical images such as photographs.Rate this question:

What type of programs make one operating system perform like another?
Correct Answer
emulatorsExplanation
Emulators are programs that enable one operating system to mimic the behavior and functionality of another operating system. They accomplish this by simulating the hardware and software environment of the target operating system, allowing software designed for that system to run on a different system. Emulators are commonly used for various purposes, such as running legacy software on modern systems, testing software compatibility, and providing a platform for cross-platform development.Rate this question:

What type of system is used for coding letters and numbers?
Correct Answer
character setExplanation
A character set is a system used for coding letters and numbers. It is a collection of characters, such as letters, digits, and symbols, that are assigned unique binary codes. These codes allow computers to represent and process text in various languages and formats. Character sets are essential for encoding and decoding information, ensuring that data can be accurately stored, transmitted, and displayed across different computer systems and devices.Rate this question:

What allows data to change into a format a computer can read?
Correct Answer
digitizeExplanation
Digitize is the process of converting data into a digital format that can be understood and processed by a computer. This involves encoding the data into binary code, which consists of ones and zeros. By digitizing data, it becomes possible for computers to read and manipulate the information. This process is essential for various tasks such as storing, transmitting, and analyzing data using computer systems.Rate this question:

What program allows useres to record music?
Correct Answer
MIDIExplanation
MIDI (Musical Instrument Digital Interface) is a protocol that allows electronic musical instruments, computers, and other devices to communicate with each other. It does not record music directly, but it enables users to connect and control various devices such as keyboards, synthesizers, and software programs that can record and playback MIDI data. Therefore, MIDI itself does not record music, but it provides the means to do so by facilitating communication between different musical devices and software.Rate this question:

RAM / hard drive space that stores frequently used data is called _____________.
Correct Answer
Disk CacheExplanation
Disk cache refers to the RAM or hard drive space that stores frequently used data. This allows for quicker access to the data, as it is readily available in the cache rather than having to be retrieved from the slower main memory or hard drive. The disk cache acts as a temporary storage area for frequently accessed data, improving overall system performance by reducing the time required to retrieve information.Rate this question:

Hardware on the motherboard that stores frequently used data is called______________.
Correct Answer
Cache memoryExplanation
Cache memory is a type of hardware on the motherboard that stores frequently used data. It is designed to provide faster access to data than the main memory (RAM). By storing frequently accessed data closer to the processor, cache memory helps to reduce the time it takes for the CPU to retrieve data, improving overall system performance. Cache memory operates at a higher speed than RAM and is typically smaller in size, but it provides quicker access to data, making it an essential component in modern computer systems.Rate this question:
