2.
Universal ___________ Bus.
Correct Answer
Serial
Explanation
The correct answer is "Serial" because Universal Serial Bus (USB) is a standard interface used for connecting devices to a computer. The word "Serial" in the answer refers to the type of communication protocol used by USB, where data is transmitted one bit at a time.
3.
RAM stands for......
Correct Answer
D. Random Access Memory
Explanation
RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. It is volatile memory, which means that its contents are lost when the power is turned off. RAM is used by the computer to store data that is currently being used by the CPU, allowing for faster data access compared to other types of memory.
4.
ROM stands for Read ______________ Memory.
Correct Answer
Only
5.
CPU stands for: Central ____________ Unit.
Correct Answer
Processing
Explanation
The correct answer for this question is "Processing." CPU stands for Central Processing Unit, which is the main component of a computer responsible for executing instructions and performing calculations. It is often referred to as the brain of the computer, as it carries out all the necessary computations and data processing tasks.
6.
What is the main circuit board to which all of the other internal components is connected. Also known as the "spine" of the computer.
Correct Answer
E. Motherboard
Explanation
The main circuit board to which all of the other internal components are connected is called the motherboard. It is often referred to as the "spine" of the computer because it provides the central communication pathway for all the components to interact with each other. The motherboard houses the CPU, RAM, and other essential components, and it also provides expansion slots for additional devices. Without the motherboard, the computer would not be able to function properly as it acts as the central hub for all the internal connections and communication.
7.
______________________ is the basic software that allows the user to interact with the computer. Also known as the language of a computer.
Correct Answer
operating system
Explanation
The operating system is the basic software that allows the user to interact with the computer. It acts as an interface between the user and the computer hardware, enabling the user to perform various tasks and run applications. It manages system resources, controls hardware devices, and provides a platform for other software to run on. The operating system is often referred to as the language of a computer because it interprets and executes user commands and provides a means for communication between the user and the computer.
8.
This is used by the computer to record and play audio by converting analog sound to digital information and back again.
Correct Answer
E. None of the above.
Explanation
The correct answer is "Sound Card". A sound card is a hardware device that allows a computer to record and play audio. It converts analog sound signals into digital information that the computer can process, and then converts the digital information back into analog sound signals that can be output through speakers or headphones. The options provided (APG, Ports, USB, IDE) are not related to the functionality described in the question.
9.
___________________ is the primary device for entering information into the computer.
Correct Answer
keyboard
key board
Explanation
The keyboard is the primary device for entering information into the computer. It allows users to input text, numbers, and commands by pressing various keys. The term "key board" is likely a typo or misspelling of "keyboard," as both terms refer to the same device.
10.
DSL stands for Digital ____________ Line.
Correct Answer
subscriber
Explanation
DSL stands for Digital Subscriber Line. This technology uses existing telephone lines to provide high-speed internet access to subscribers. By utilizing the existing infrastructure, DSL allows for faster transmission of digital data, such as internet traffic, without interfering with traditional telephone services. Therefore, the correct answer is "subscriber" as it refers to the individuals or businesses who subscribe to DSL services to access the internet.
11.
An electrical transformer regulates the electricity used by the computer.
Correct Answer
E. Power supply
Explanation
The power supply is responsible for regulating the electricity used by the computer. It takes the incoming electrical power and converts it into the appropriate voltage and current needed by the computer components. Without a properly functioning power supply, the computer would not receive the correct amount of power and may not function properly. Therefore, the power supply is crucial in regulating the electricity and ensuring the computer operates efficiently.
12.
Name one of the four types of permanent storage areas.
Correct Answer
ROM / BIOS
removable drives
network / internet storage
hard drive
Explanation
The correct answer is all of the above. ROM / BIOS, removable drives, network / internet storage, and hard drive are all types of permanent storage areas. ROM / BIOS refers to read-only memory or basic input/output system, which contains firmware that is permanently stored and cannot be altered. Removable drives such as USB flash drives or external hard drives provide portable and permanent storage options. Network / internet storage allows users to store and access files remotely over a network or the internet. Hard drives are the primary storage devices found in computers and provide permanent storage for data and programs.
13.
There are two ways to measure the performance of a hard disk. Name one.
Correct Answer
data rate
seek time
Explanation
The performance of a hard disk can be measured in terms of its data rate, which refers to the speed at which data can be read from or written to the disk. It indicates how quickly data can be transferred to and from the disk. Another way to measure the performance of a hard disk is through its seek time, which is the time taken by the disk to locate and access a specific piece of data. Seek time is a measure of how quickly the disk's read/write heads can move to the desired location on the disk.
