Does SMART mean self-monitoring?
Introduction S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; often written as SMART) is a monitoring system for computer hard disk drives to detect and report on various indicators of reliability, in the hope of anticipating (predicting) failures.
SMART is an interface between the platform’s BIOS and the storage device. When SMART is enabled in the BIOS (mostly default), the BIOS can process information from the storage device and determine whether to send a warning message about potential failure of the storage device. The purpose of SMART is to warn a user of impending drive failure while there is still time to take action, such as backing up the data or copying the data to a replacement device.
The Self-Monitoring, Analysis, and Reporting Technology (SMART) feature set allows for the protection of user data and minimizes the likelihood of unscheduled system downtime that may be caused by predictable degradation and/or fault of the device. SMART feature set devices attempt to predict the likelihood of near-term degradation or fault condition.
- The SMART feature set provides the host with the knowledge of a negative reliability condition.
- A drive that implements SMART may optionally implement a number of self-test or maintenance routines, and the results of the tests are kept in the self-test log.
- More detail on the health of the drive may be obtained by examining the S.M.A.R.T.
Attributes, which provide statistics on specific set of attributes. The drive has set of attributes with predefined threshold values beyond which attributes should not pass under normal operation. SMART Attributes Each drive manufacturer defines a set of attributes and sets threshold values beyond which attributes should not pass under normal operation.
- Each attribute has a raw value, whose meaning is entirely up to the drive manufacturer (but often corresponds to counts or a physical unit, such as degrees Celsius or seconds).
- A S.M.A.R.T.
- Attribute contains the following fields: – Identifier : the meaning of the attribute – Data (Raw): raw measured values are stored in this field, provided by a sensor or a counter.
This data is then processed by an algorithm designed by the storage device manufacturer – Threshold : the (failure) limit value for the attribute – Value: the current relative “health” of the attribute. This number is calculated by the algorithm, using the raw data – Worst : the worst (smallest) value ever found in the previous lifetime of the storage device An attribute is correct, when the Value is greater than or equal with the Threshold.
If this is not true for a critical attribute, failure is predicted, the device is considered bad and it should be replaced immediately (the attribute determines the problem). If the Threshold is 0 for any attribute, that attribute is not able to predict failure (because the Value cannot be less than 0).
SMART Self-Tests Devices, which support SMART, may offer a number of self-tests: – Short – Checks the electrical and mechanical performance as well as the read/write operations of the device. Scans portion of the drive’s media (area is vendor-specific and there is a time limit on the test). Not only in client, SMART failure in a server at the BIOS level: SMART failure at the Operating System level: SMART Attributes Examples of SMART attributes, showing the
What is SMART monitoring?
Self-Monitoring, Analysis and Reporting Technology Self-monitoring, analysis and reporting technology (SMART) is a fault detection, monitoring and maintenance technology used by computers to provide advanced notification for hard disk drive (HDD) failures. In 1992, IBM launched SMART for their AS/400 disk array servers to identify and predict hard drive errors.
Is the word SMART refers to Self-Monitoring, Analysis and Reporting Technology?
Stands for ‘Self-Monitoring Analysis and Reporting Technology.’ SMART is a monitoring system that is built into hard disk drives and solid-state drives that detects and reports errors that may lead to drive failure.
What is counted as SMART?
IQ tests can measure language, processing, memory, and reasoning. Your score tends to remain consistent from childhood to adulthood. IQ stands for intelligence quotient. IQ tests are tools to measure intellectual abilities and potential. They’re designed to reflect a wide range of cognitive skills, such as reasoning, logic, and problem-solving.
- It’s a test of intelligence, something you’re largely born with.
- It’s not a test of knowledge, which represents what you learn through education or life experience.
- To know your IQ, you take a standardized test in the presence of a trained professional.
- IQ tests you find online might be entertaining, but the results aren’t valid.
It’s also important to understand that your IQ score doesn’t exist in isolation. The number actually represents how your results compare to those of other people your age. A score of 116 or more is considered above average, A score of 130 or higher signals a high IQ.
- Membership in Mensa, the High IQ society, includes people who score in the top 2 percent, which is usually 132 or higher.
- Eep reading as we explore more about high IQ, what it means, and what it doesn’t mean.
- IQ tests have gone through significant changes through the decades to correct for racial, gender, and social biases, as well as cultural norms.
Today, there are several versions in use. They may have different methods of scoring, but they all use 100 as the average. IQ scores follow a bell curve. The very peak of the bell represents the average score of 100. Lower scores are represented on one slope of the bell while higher scores are represented on the other.
What does self SMART mean?
SELF SMART (intrapersonal intelligence) involves knowledge of the internal aspects of the self, such as knowledge of feelings, the range of emotional responses, thinking processes, and self-reflection. This intelligence allows us to step back from ourselves and watch ourselves as an observer.
What is SMART attributes?
S.M.A.R.T. Attributes Each drive manufacturer defines a set of attributes and selects threshold values which attributes should not go below under normal operation. Attribute values can range from 1 to 253 (1 representing the worst case and 253 representing the best).
- Depending on the manufacturer, a value of 100 or 200 will often be chosen as the “normal” value.
- Manufacturers that have supported one or more S.M.A.R.T.
- Attributes in various products include: Samsung, Seagate, IBM ( Hitachi), Fujitsu, Maxtor, Western Digital.
- These manufacturers do not necessarily agree on precise attribute definitions and measurement units; therefore the following list should be regarded as a general reference only.
Note that the attribute values are always mapped to the range of 1 to 253 in a way that means higher values are better. For example, the “Reallocated Sectors Count” attribute value decreases as the number of reallocated sectors increases. In this case, the attribute’s raw value will often indicate the actual number of sectors that were reallocated, although vendors are in no way required to adhere to this convention.
What is SMART in hard disk?
S.M.A.R.T. (or simply SMART) is a monitoring system built into most modern hard drives.S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology. The technology helps detect various reliability problems at an early stage, giving warning signs well in advance before the hard drive fails.
- By reading (and interpreting) the indicators, the user can prevent data loss by replacing the disk before the crash occurs.
- But what S.M.A.R.T.
- Flags should we look at? There are dozens available! This article talks about tools to use and parameters to check for to prevent accidental data loss due to hard drive failure.
The Tools Before you begin, you’ll need a tool to read the many S.M.A.R.T. parameters available in your hard drive. There are many free tools that can display and decode the many available S.M.A.R.T. parameters. Hard Drive S.M.A.R.T. Parameters With so many different parameters available, which ones give a warning sign? This is not an easy question to answer, as different manufacturers support different subsets of reporting variables.
In addition, raw values you see in the rightmost column are vendor-specific, meaning nothing before they are decoded. However, there are some parameters that are supported by most manufacturers (for example AData, PQI, Transcend). Most S.M.A.R.T. tools calculate drive’s health by analyzing the following variables: Reallocated Sectors Count, Current Pending Sectors Count, and Uncorrectable Sector Count.
Manufacturer supplied disk analysis tools can use other (vendor-specific) parameters as well to perform a more in-depth analysis of the drive’s health.
Reallocated Sectors Count. This parameter gives a good hint on the overall health of the drive. It represents the number of sectors that were found bad and were remapped to a special zone (reserved area) of the hard disk. Normally, new hard drives should have zero reallocated sectors. With use, you may get an occasional instance or two; this usually does not represent a serious problem. What does represent a problem is a situation where the number of reallocated sectors is steadily increasing with time. This means the disk is slowly failing; get a replacement ASAP before you start getting uncorrectable read errors (see below). Current Pending Sector Count. The meaning of this value is highly dependent on disk manufacturers. A rise in Current Pending Sector Count may mean there are unstable (but not necessarily outright bad) sectors on the drive. If the count of pending sectors increases with time, it’s time to replace the disk. Uncorrectable Sector Count. When a sector is so bad it can’t be read for remapping, the Uncorrectable Sector Count variable increases. The variable represents the count of uncorrectable errors when reading/writing a sector from the disk surface. If the value of this attribute increases, this indicates mechanical problems or defects of the disk surface. A replacement disk should be used as soon as possible. Read Error Rate. This parameter stores data about the rate of hardware read errors that occurred when reading data from the disk. The raw value is manufacturer dependent, so it’s difficult to interpret correctly. This parameter may not mean much to generic S.M.A.R.T. analysis tools, but is often used by disk diagnostic tools supplied by hard drive manufacturers. Write Error Rate. Indicates errors while recording data into disk. Vendor-specific value, mostly used by manufacturer supplied HDD diagnostic tools. Reallocation Event Count. The value stores the count of sector reallocation operations. Both successful and unsuccessful attempts are counted. This value supplements the reading of Reallocated Sectors Count, but is sometimes omitted (not recorded) by some models/manufacturers. A rise in Reallocation Event Count means the hard drive is deteriorating. Spin Retry Count. This value stores the number of retries during disk spin-up. A growing value may be a sign of an upcoming mechanical failure.
Why use smart sensors?
What is a Smart Sensor and How Does it Work? | Definition from TechTarget A smart sensor is a device that takes input from the physical environment and uses built-in compute resources to perform predefined functions upon detection of specific input and then process data before passing it on.
Smart sensors enable more accurate and automated collection of environmental data with less erroneous noise among the accurately recorded information. These devices are used for monitoring and control mechanisms in a variety of environments, including smart grids, battlefield reconnaissance, exploration and many science applications.
The smart sensor is also a crucial and integral element in the, IoT technology makes it possible to provide a unique identifier for almost anything and to transmit data from or about those things over the internet or a similar sensor network. One implementation of smart sensors is as components of a, which can have thousands of nodes.
- Each node is connected to one or more other sensors and sensor hubs as well as to individual actuators.
- Low-power mobile microprocessors typically provide compute resources in IoT environments.
- At a minimum, a smart sensor is made of a sensor, a microprocessor and wireless communication technology of some kind.
The compute resources must be an integral part of the physical design. A sensor that just sends its data along for remote processing isn’t considered a smart sensor. A smart sensor has three components: a sensor that captures data, a microprocessor that computes on the output of the sensor via programming and communications capabilities. A smart sensor might also include several other components besides the primary sensor.
- These components can include, amplifiers, excitation control, analog filters,, and compensation that provides a built-in correction of less-than-ideal measurements or output.
- A smart sensor also incorporates software-defined elements that provide functions such as, digital processing and communication to external devices.
A smart sensor connects a raw base sensor to integrated computing resources that enable the sensor’s input to be processed. The base sensor is the component that provides the sensing capability. It might be designed to sense heat, light or pressure. Often, the base sensor will produce an analog signal from an application algorithm that must be processed before it can be used.
This process is also called, At this point, an intelligent sensor’s integrated technology comes into play. In signal processing, an onboard microprocessor uses a technique called filtering to and convert the sensor’s signal into a usable, digital format. Smart sensor technology also contain integrated communications capabilities that let them connect to a private cloud computing environment or the internet.
This lets them communicate with external devices. Smart sensors have many uses. They’re commonly found in industrial environments and are the driving force behind and industrial automation, robotics and other advanced instrumentation. Factories often use smart sensors for diagnostic purposes.
- Smart temperature sensors ensure machines aren’t overheating, and vibration sensors monitor machines at risk of vibrating loose.
- Smart sensors also enable process control, such as monitoring a manufacturing process and making necessary adjustments so it can meet quality or production goals.
- These were once manual processes, but smart sensors have automated them.
Smart sensors also play a key role in the advancement of modern security systems. Thermal imaging sensors detect an intruder’s body heat. Similarly, devices such as, motion sensors, and window and door sensors are commonly connected to a common network.
Level sensors. These are used to measure the volume of space taken up in a container. A vehicle’s fuel gauge might be connected to a level sensor that monitors the level of fuel in the tank. Temperature sensors. These monitor a component’s temperature so a corrective action can be taken if the temperature gets too high or low. For example, in an industrial setting, a temperature sensor is used to ensure machinery doesn’t overheat. Pressure sensors. These are used to monitor the pressure of gases or fluids in a pipeline. A sudden drop in pressure might indicate a leak or a flow control system issue. Infrared sensors. These are used in thermal imaging cameras and noncontact infrared thermometers are used for temperature monitoring. Other infrared sensors are optical sensors tuned to a frequency that helps them see light in the, These sensors are used in medical equipment, such as pulse oximetry devices, and in electronic devices designed for remote control operation. Proximity sensors. These are used to detect the location of a person or object in relation to the sensor. In retail environments, proximity sensors can track customer movements throughout the store.
Other smart sensors can monitor electrical power consumption; vibration, such as in the case of factory equipment; humidity; moisture; and light. Flow sensors monitor in-home water systems for leaks and send alerts if one is detected. Smart sensors come with a range of benefits, but they also have challenges and drawbacks.
What are SMART logs?
Drive Logs ¶ – The View Logs section displays the content of various drive logs. These logs contain information and errors, usually related to self-tests and potentially other errors encountered by the disk. To view drive logs:
Navigate to Diagnostics > SMART Status Locate the View Logs panel on the page Select the Device to view Select the Log Type Click View
There are numerous logs available, but some logs are only present on specific types of devices, and some devices may not support certain logs even if they are the correct type. Summary Error Log The Error log on a drive contains a record of errors encountered during the drive’s operation, such as read errors, uncorrectable errors, CRC errors, and so on.
- Running an Offline test will also make the drive print more errors here if they are found during the test.
- Extended Error Log Similar to the summary error log but allows for longer and more detailed error messages.
- SMART Self-Test Log The Self-test logs contain a record of several recent self-tests run on the drive.
It shows the type of test, the results of the test, and in the case of tests that were stopped prematurely, it shows the percentage of the test remaining. If an error is encountered during a test, the first logical block address (LBA) is printed to help determine where in the disk the problem lies.
Extended Self-Test Log Similar to the SMART self-test log but allows for longer and more detailed error messages. Selective Self-Test Log Shows the results of recent selective self-tests and the min/max LBA sets which were included in the test. Log Directory Prints the contents of the device log directory, which includes a list of logs and their current sizes.
Device Temperature Log (ATA Only) The disk temperature information log from the SMART command transport. Prints both the current temperature and a temperature history with an ASCII graph. Device Statistics (ATA Only) Values and descriptions of ATA device statistics logged by the drive.
Is SMART an acronym technology?
The term ‘smart’ is in fact an abbreviation for ‘Self-Monitoring Analysis and Reporting Technology ‘, although it is used with its actual meaning of ‘clever’ to describe any kind of available technology that allows users to connect with internet networks.
What is SMART vs KPI?
SMART goals and KPIs Goals aren’t KPIs, but KPIs support your goals. Your SMART goal is the result you want to attain, and the KPI shows you if you’re on the right track. Thus, used as part of your SMART goals, KPIs can be especially useful in the Measurement element of your goal.

- What are SMART goals? Acronym Explained
April 10, 2023 SMART is an acronym for S pecific, M easurable, A ssignable, R ealistic and T ime-Related. Businesses use SMART to help determine if a goal is viable. The concept was originally developed in 1981 as a way to write meaningful objectives. SMART goals are a popular project management technique.
Are there different types of smart?
What kind of smarts are there? – There are nine kind of smarts these are: Naturalistic, Musical, Logical–mathematical, Existential, Interpersonal, Linguistic, Bodily–kinaesthetic, Intra–personal and Spatial smarts.
What makes a smart?
The intellectual capacity of a smart person – Intelligence is directly tied to intellectual capacity. It’s about being able to learn, remember, and use new information to solve problems and adapt to new situations. There are some illustrious names like Charles Spearman or Francis Galton at the beginning of the study we mentioned above.
However, Binet stands out because the context in which he developed his work was educational. Also, his interest in studying intelligence was about improving the educational system. He wanted to know if there was a way to intervene in children with learning difficulties. Along with his colleague, Theodore Simon, Binet designed a test to try to measure the intellectual ability of children,
To do so, they created individual test items for the children to answer according to their age. For example:
- A three-year-old should be able to point to their mouth and eyes.
- A nine-year-old should be able to name the months of the year in order.
- Finally, a twelve-year-old should be able to name sixty words in three minutes.
This assessment was the first IQ test:
What determines being smart?
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. Intelligence is challenging to study, in part because it can be defined and measured in different ways. Most definitions of intelligence include the ability to learn from experiences and adapt to changing environments.
- Elements of intelligence include the ability to reason, plan, solve problems, think abstractly, and understand complex ideas.
- Many studies rely on a measure of intelligence called the intelligence quotient (IQ).
- Researchers have conducted many studies to look for genes that influence intelligence.
- Many of these studies have focused on similarities and differences in IQ within families, particularly looking at adopted children and twins.
Other studies have examined variations across the entire genomes of many people (an approach called genome-wide association studies or GWAS) to determine whether any specific areas of the genome are associated with IQ. Studies have not conclusively identified any genes that have major roles in differences in intelligence.
It is likely that a large number of genes are involved, each of which makes only a small contribution to a person’s intelligence. Other areas that contribute to intelligence, such as memory and verbal ability, involve additional genetic factors. Intelligence is also strongly influenced by the environment.
During a child’s development, factors that contribute to intelligence include their home environment and parenting, education and availability of learning resources, and healthcare and nutrition. A person’s environment and genes influence each other, and it can be challenging to tease apart the effects of the environment from those of genetics.
What is an example of being smart?
smart vs. intelligent – In general, the words and are both used to describe a person who has a sharp mind and is mentally capable. For example, a person who can correctly use calculus would typically be described as either smart or intelligent, In many contexts, smart and intelligent are used as interchangeable synonyms.
- However, they each have some of their own senses.
- For example, only intelligent is used to refer to something that is capable of using reason or understanding at all.
- When we wonder if there’s intelligent life on other planets, we’re wondering if there are other creatures that are able to reason like humans can.
And when we discuss computers as being artificially intelligent or having artificial intelligence, we mean that they are able to understand meanings and use reason similarly to how a person can. Smart can mean “saucy” or “brash” or “fashionable,” while intelligent can’t.
I get so frustrated with my brother’s smart comments about how my car won’t start because it’s old. James was a smart dresser, wearing a tie and three-piece suit every day to work. It may only be a paper cut, but it still smarts.
And sometimes small distinctions between the two words are made. Smart is often used to describe a person who has improved their mind through study and learning, while intelligent is used to describe a person who was born with mental sharpness or is naturally good at learning.
What is natural smart?
What Is It? Nature smarts (or naturalistic intelligence) is the ability to know about and relate well to one’s natural surroundings. This includes having a greater sensitivity to nature and one’s place within it, being able to nurture and grow things, and easily caring for and interacting with animals.
What is the difference between smart and logical?
Logic vs Intelligence – Logic is associated with formal systems for validating arguments and inferring new information from known facts. Intelligence is associated with the human mind and the ability to solve problems in dynamic ways.For a given problem, it is possible to come up with a large number of solutions that are logically valid.
What is meant by self-monitoring?
Self-monitoring is a strategy that teaches students to self-assess their behavior and record the results. Though it does not create new skills or knowledge, self-monitoring does increase or decrease the frequency, intensity, or duration of existing behavior. It also saves teachers time monitoring students’ behavior.
What is an example of self-monitoring?
An example of self-monitoring at work could include using a checklist to stay focused on the tasks you need to complete and observing how often you get off task with non-work related activities.
Do SMART people have self awareness?
2. Self-awareness is one of the reasons – Regardless of the hypersensitivity to external stimuli, smart people are usually self-aware. Not only are they attentive to those around them but also concerned about their personal performance. Smart people experience the “spotlight” more often.
Do SMART people have self-control?
9. They can connect seemingly unrelated concepts – Several Quora users suggested that smart people are able to see patterns where others can’t. That’s because they can draw parallels between seemingly disparate ideas. As April Astoria notes : “You think there’s no relation between sashimi and watermelon? You’d be wrong.
