The answer is Database.
Reason being is because because the definition of database matches the statement.
- Collection of information that is organized so that it can be easily accessed, managed and updated.
The four components of computer are explained clearly.
<u>Explanation:</u>
- Hardware is the electrical physical parts that a computer system needs to function. It organizes all the process by a circuit board that operates within a PC or laptop; built with the "motherboard", "graphics card", "CPU (Central Processing Unit)", "ventilation fans", "webcam", "power supply", and so on. Without hardware, there is no means of running the necessary software that makes computers so valuable.
- Software is a program that facilitates a computer to execute a particular task, as objected to the hardware. Computer software has to be "stored" into the computer's storage (such as a hard drive, memory, or RAM). Working computer systems segment software into three major classes: system software, programming software, and application software.
- A user is a person who handles a computer or network service. Users of computer and software output regularly require the technical expertise needed to fully know how they operate.
- Data is defined as bases or figures, or knowledge that's saved in or utilized by a computer. This data will be in the form of text documents, images, audio clips, software programs, or other types of data. Computer data may be prepared by the CPU and are saved in files and folders on the hard disk.
Answer:
B. the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.
Explanation:
Sound can be defined as mechanical waves that are highly dependent on matter for their propagation and transmission. Sound travels faster through solids than it does through either liquids or gases.
Signal-to-noise ratio (SNR) is simply the ratio of signal power to noise power or the ratio of desired information to the undesired signal. SNR doesn't have a unit i.e it is a unitless quantity.
Generally, the higher the signal-to-noise ratio (SNR), the better would be the quality of a signal.
Additionally, a negative signal-to-noise ratio (SNR) in decibel form simply means that the signal power is lesser than the noise power.
Hence, the correct statement regarding the signal-to-noise ratio (SNR) is that the noise (i.e., noise floor) in the signal-to-noise ratio, is a wideband noise product that is predominated by thermal noise.
Note: noise can be defined as an unwanted disturbance or undesired signal present in an electrical signal.
