What are the types of monitors we can use with computers?
Correct Answer
B. CRT and LCD
Explanation
The types of monitors that can be used with computers are CRT and LCD. CRT stands for Cathode Ray Tube and LCD stands for Liquid Crystal Display. CRT monitors use a cathode ray tube to display images, while LCD monitors use liquid crystals to display images. Both types of monitors have been widely used in the past, but LCD monitors have become more popular in recent years due to their slim design and energy efficiency.

What are the 3 most important parts of a MOTHERBOARD?
Correct Answer
C. Power Port, Battery, PCI & RAM Slots
Explanation
The three most important parts of a motherboard are the power port, battery, and PCI & RAM slots. The power port is essential for supplying electricity to the motherboard and its components. The battery is responsible for providing backup power to maintain the motherboard's settings and clock. The PCI & RAM slots are crucial for expanding the motherboard's capabilities by allowing the installation of additional hardware components such as graphics cards and RAM modules.

What are the 3 most important parts of a MICROPROCESSOR?
Correct Answer
A. Microchip, Heat Sink, Fan
Explanation
The correct answer is Microchip, Heat Sink, Fan. These three components are essential for the proper functioning of a microprocessor. The microchip is the central processing unit that carries out the instructions and calculations. The heat sink is responsible for dissipating the heat generated by the microchip to prevent overheating. The fan helps to cool down the heat sink and maintain a suitable temperature for the microprocessor. Together, these three parts ensure the efficient and reliable operation of the microprocessor.

TRUE OR FALSE:
An external hard drive is an example of an input and output device.
Correct Answer
A. TRUE
Explanation
An external hard drive can be considered as an example of an input and output device because it allows users to both input data from their computer to the hard drive and output data from the hard drive to their computer. Users can transfer files and data to the external hard drive (input) and retrieve files and data from the external hard drive (output). Therefore, it can be categorized as both an input and output device.
5.
TRUE OR FALSE:
Dual Layer DVDs hold less information than a regular DVD
Correct Answer
B. FALSE
Explanation
Dual Layer DVDs actually hold more information than regular DVDs. Regular DVDs typically have a single layer that can hold up to 4.7GB of data, while dual layer DVDs have an additional layer that can hold an additional 4.7GB, resulting in a total capacity of 8.5GB. Therefore, the statement that dual layer DVDs hold less information than regular DVDs is false.
6.
TRUE OR FALSE:
A CD/DVD ROM can create a CD/DVD.
Correct Answer
B. FALSE
Explanation
A CD/DVD ROM (Read-Only Memory) is a device that can only read data from a CD or DVD. It is not capable of creating or writing data onto a CD or DVD. Therefore, the statement "A CD/DVD ROM can create a CD/DVD" is false.
7.
What is the device that helps us connect to the Internet called?
Correct Answer
A. Modem
Explanation
A modem is a device that helps us connect to the Internet. It is responsible for converting digital signals from our computer into analog signals that can be transmitted over telephone lines or cable lines. The modem then receives analog signals from the Internet and converts them back into digital signals that our computer can understand. This allows us to access and browse the Internet.
8.
What does RAM stand for?
Correct Answer
B. Random Access Memory
Explanation
RAM stands for Random Access Memory. It is a type of computer memory that allows data to be stored and retrieved by the computer's processor quickly and efficiently. Unlike other types of memory, such as hard drives or solid-state drives, RAM is volatile, meaning that its contents are lost when the computer is turned off or restarted. RAM is an essential component of a computer system as it provides temporary storage for data that is actively being used by the processor, allowing for faster access and execution of tasks.
9.
Which are examples of an input AND an ouput device
Correct Answer
C. Keyboard, Printer
Explanation
Keyboard and printer are examples of both input and output devices. A keyboard allows the user to input data into a computer by typing, while a printer allows the computer to output data by printing documents or images. Both devices can be used for both input and output purposes, making them examples of dual-function devices.
10.
What does an ink jet printer use to create a print job?
Correct Answer
D. Ink cartridges
Explanation
An ink jet printer uses ink cartridges to create a print job. Ink cartridges contain liquid ink that is sprayed onto the paper in tiny droplets to form the desired text or image. The printer's mechanism controls the movement of the cartridges and the precise release of ink, resulting in high-quality prints.
11.
What does a laser printer use to make a print job?
Correct Answer
A. Toner and static electricity
Explanation
A laser printer uses toner and static electricity to make a print job. Toner is a powder-like substance that is attracted to areas of the paper that have been charged with static electricity. The laser inside the printer creates an image on a drum using static electricity, which then attracts the toner particles. The toner is then transferred onto the paper and fused onto it using heat and pressure, resulting in a printed document.
12.
The microprocessor is like this part of the human body.
Correct Answer
D. Brains
Explanation
The correct answer is "Brains." The comparison suggests that the microprocessor is similar to the brain in the human body. Just like the brain controls and processes information, the microprocessor is responsible for controlling and processing data in a computer system. Both are essential for proper functioning and decision-making.
13.
The motherboard acts like this part of the human body.
Correct Answer
A. Nerves
Explanation
The motherboard acts like the nerves in the human body. Just like nerves transmit signals between different parts of the body, the motherboard connects and allows communication between various components of a computer system. It facilitates the flow of data and instructions between the processor, memory, storage devices, and other peripherals, similar to how nerves transmit signals between the brain and different organs.
