Static electricity stays intact until something causes it to discharge. This means that the static charge remains until it is transferred or neutralized by coming into contact with a conductor or another object with a different charge. Once the discharge occurs, the static electricity is no longer present.

The first job that the basic input output system (BIOS) does at start-up is to run the power-on self-test (POST). The POST is a series of diagnostic tests that the BIOS performs to check the hardware components of the computer system. It ensures that all essential hardware components are functioning properly before proceeding with the boot process. This helps in identifying any potential issues or errors that may prevent the system from starting up successfully.

Static electricity remains intact until it is discharged. Discharging refers to the process of releasing or transferring the excess electric charge from an object to the ground or another object with a lower electric potential. When static electricity is discharged, the accumulation of electric charge is balanced, and the object returns to a neutral state. This can happen through various means, such as through contact with a conductor or through a spark or electric discharge. Once discharged, the object no longer carries a static electric charge.

The Power-on-Self-test (POST) is a diagnostic program that runs when a computer is turned on to check if all the hardware components, including the CPU, are functioning properly. It detects any hardware problems in the CPU by running a series of tests to ensure that all the components are working correctly. Therefore, the POST is specifically designed to detect if a CPU hardware problem exists.

The correct answer is always classified to the highest classification of the material within the container. This means that the combination to any security container is always classified at the same level as the highest classified material that is stored within the container. This ensures that the container provides the appropriate level of protection for the sensitive information or materials it contains.

Polling refers to the process of actively sampling the status of an external device by a client program. In this method, the client program regularly checks the device to see if there is any new information or if any action needs to be taken. It is a common technique used in computer programming to interact with external hardware or devices.

Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle. It ensures that the data is whole and complete, without any errors or inconsistencies. Data integrity is crucial in maintaining the quality and trustworthiness of data, especially in databases and information systems. It involves various measures and techniques to prevent data corruption, unauthorized modifications, or loss of data. Therefore, data integrity is the term that describes the data as whole or complete.

Primary communications security responsible officers must hold the rank of SSgt.

The correct answer is Unit deployment manager and commander. The unit deployment manager and commander should be notified immediately of any predeployment shortfalls in order to address and resolve any issues that may affect the deployment process. They are responsible for overseeing the deployment of personnel and equipment, and ensuring that all necessary resources are available for a successful deployment. By notifying them promptly, any shortfalls can be addressed and necessary actions can be taken to mitigate any potential impact on the deployment.

BIOS stands for Basic Input/Output System. It is a form of firmware that contains the computer's startup instructions. It is responsible for initializing and testing hardware components during the boot process, and it also provides a set of low-level software routines that allow the operating system to communicate with the hardware. The BIOS is stored on a chip on the motherboard and is essential for the computer to start up and function properly.

A driver is a small, low-level program used by the computer operating system to interact with hardware devices. It acts as a bridge between the hardware and the operating system, allowing the operating system to communicate with and control the hardware. Drivers are essential for the proper functioning of hardware devices, as they provide the necessary instructions and protocols for the operating system to utilize the hardware effectively.

Placing masking tape on the cables and connection points is a simple method of identifying cables when troubleshooting hardware. This allows for easy identification and organization of the cables, making it easier to track and troubleshoot any issues. It also helps prevent confusion and ensures that the cables are properly connected.

Predeployment is the phase that focuses on exercises to ensure familiarity with the deployment process and equipment. This phase occurs before the actual deployment and is crucial in preparing individuals for the tasks and challenges they may face during deployment. It allows for practice and training to ensure that all personnel are well-prepared and confident in their abilities to handle the deployment process and effectively use their equipment.

Electrostatic discharge refers to the sudden and momentary electric current that occurs between two objects at different electrical potentials. This discharge happens when there is a buildup of static electricity on one object, and it is transferred to another object with a lower electrical potential. It can occur due to various reasons such as friction, contact, or separation of materials. This discharge can be hazardous and cause damage to electronic devices, which is why precautions such as grounding and using anti-static measures are necessary.

An interrupt is defined as an asynchronous signal from a computer hardware device indicating the need for attention from a central processing unit (CPU) or a synchronous event. It is a mechanism used by hardware devices to communicate with the CPU and request its attention. When an interrupt occurs, the CPU suspends its current execution and handles the interrupt request. This allows the CPU to prioritize and respond to different events or devices in a timely manner, ensuring efficient processing of tasks.

BIOS, or Basic Input/Output System, is responsible for initializing communication with all hardware devices in a computer system. It performs a power-on self-test (POST) during the boot process and checks if all hardware components are functioning properly. If a keyboard or mouse is not found, BIOS sends an error message to the user. Therefore, BIOS is the correct answer for the given question.

To prevent the build-up of static electricity, grounding the electrostatic discharge sensitive devices is necessary. This is because grounding provides a pathway for the static electricity to flow into the ground, preventing it from accumulating on the devices. By doing so, the risk of damaging the devices or causing a discharge that could harm individuals or disrupt the operation of electronic equipment is minimized. Checking the relative humidity level, disconnecting the circuit from the device, or turning the power switch to the off position may not directly address the issue of static electricity build-up.

The CMOS (Complementary metal-oxide semiconductor) component uses a lithium battery to maintain computer settings when power is removed. CMOS is responsible for storing the BIOS (Basic input output system) settings, including date, time, and hardware configuration. The lithium battery provides a continuous power supply to the CMOS chip, ensuring that the settings are not lost when the computer is turned off or unplugged. This allows the computer to retain its configuration and settings even when not connected to a power source.

Cache is the correct answer because most modern computers have two or three levels of memory, and cache is one of those levels. Cache memory is a small and fast memory that is closer to the CPU, allowing for quick access to frequently used data and instructions. It helps to improve the computer's overall performance by reducing the time it takes to retrieve data from the slower main memory.

After the computer goes through the initial steps of the boot up process, such as the keyboard lights flashing and the memory test being visible on the monitor, the next and final step is for the operating system (OS) to load into memory. Once this happens, the user interface appears, allowing the user to interact with the computer and access its features and functions.

The preferred method for listing material on the Air Force COMSEC Form 16 is alphabetically by short title. This means that the materials should be organized and listed in alphabetical order based on their short titles. This method allows for easy and efficient referencing and retrieval of the materials when needed.

If it is physically impossible to conduct an inventory of a user because of distance, the COMSEC manager would ask the user to verify his or her holding by letter or message. This method allows the COMSEC manager to obtain the necessary information from the user without physically being present. It is a practical solution when conducting an inventory in person is not feasible due to distance constraints.

Survivability is the TDC characteristic that requires equipment to be capable of operation and maintenance by personnel wearing nuclear, biological, and chemical protective gear. This means that the equipment must be designed and built to withstand and operate in hazardous environments where nuclear, biological, and chemical threats are present. It ensures that the equipment can continue to function and be maintained even in these challenging conditions, thus enhancing the safety and effectiveness of the personnel using it.

The CMOS (Complementary metal-oxide semiconductor) is very susceptible to damage from electrostatic discharge. CMOS is a type of semiconductor technology used in microprocessors and other digital logic circuits. It is sensitive to static electricity, which can cause permanent damage to the component. Therefore, proper handling and precautions must be taken when working with CMOS to prevent electrostatic discharge.

Nonvolatile memory refers to a type of computer memory that retains its stored data even when the power is turned off or lost. Among the options provided, Read-Only Memory (ROM) is considered as nonvolatile memory. ROM is a type of memory that stores permanent data and instructions that cannot be modified or erased by normal computer operations. It is commonly used to store firmware, such as the BIOS, which is essential for booting up the computer. Unlike volatile memory, which loses its data when the power is turned off, ROM retains its contents, making it a nonvolatile memory option.

The floppy disk controller typically uses IRQ line number 6. IRQ lines are used by devices to request the attention of the CPU. Each device is assigned a specific IRQ line number to avoid conflicts. In the case of the floppy disk controller, it commonly uses IRQ 6 to communicate with the CPU and handle disk operations.

Class I of electrostatic discharge (ESD) refers to items that are sensitive to voltages below 1000 volts. Since the item in question is sensitive to 900 volts, it falls under Class I.

After initial power is applied, the next step in the boot-up process is for the keyboard lights to flash. This is a common indication that the computer is receiving power and initializing its hardware components. It does not necessarily mean that the operating system has loaded or that the user interface is visible.

This COMSEC material requires the most strenuous accounting practices by using an accounting control number. The answer "Accounting legend code (ALC)-1" suggests that ALC-1 is the specific accounting control number that should be used for this COMSEC material. This indicates that the material is of high importance and requires strict accounting procedures to ensure its security and proper handling.

The maximum number of different actions that can be accomplished on a single Stand Form 153 is 1. This means that there is only one action that can be performed on this specific form.

The term used when referring to specific COMSEC material other than equipment is "aids". This term is used to describe any additional materials or resources that are used to support the secure communication and protection of sensitive information. These aids can include things like key cards, codebooks, or cryptographic algorithms that are used in conjunction with the equipment to ensure the confidentiality and integrity of the communications.

The characteristic of theater deployable communications that requires equipment setup times to be kept to a minimum is mobility. In a deployed environment, it is crucial to be able to quickly transport, deploy, and operate the communication equipment. This allows for flexibility and adaptability in rapidly changing situations. By minimizing setup times, the communication system can be easily moved and reconfigured as needed, ensuring effective communication capabilities in the theater of operations.

Fault isolation is the correct answer because it refers to the process of collecting and analyzing data to determine the cause of an operational failure and how to prevent it from recurring. This involves identifying and isolating the specific fault or problem that led to the failure, in order to address it effectively and prevent it from happening again in the future.

Memory chips are the easiest hardware installation on a computer because they can be easily inserted into the memory slots on the motherboard. Unlike other hardware components such as the video card, CPU, or motherboard, memory chips do not require additional cables or connectors. They simply need to be properly aligned and firmly inserted into the memory slots. This process is relatively simple and can be done by most computer users without any technical expertise.

Items that are sensitive to more than 4000 but less than 15000 volts fall into category III.

When either installing or removing an electrostatic discharge sensitive (ESDS) device, the first step you must take is to turn the power switch to the off position. This is important to ensure that there is no electrical current flowing through the device, reducing the risk of electrostatic discharge and potential damage to the device. Grounding the ESDS device, checking the relative humidity level, and disconnecting the circuit from the device may be necessary steps in the process, but they should be done after turning off the power switch.

The individual who is required to use and safeguard COMSEC aids while performing official duties is the user. This means that the person is responsible for utilizing and protecting communication security equipment and materials in their role. They must follow proper procedures and protocols to ensure the confidentiality and integrity of sensitive information. The user plays a crucial role in maintaining the security of communication systems and preventing unauthorized access or disclosure.

Disposition records and/or destruction reports are not required for material that has been issued to Transient Aircrews. This means that when material is issued to Transient Aircrews, there is no need to keep records of its disposition or report its destruction. This could be because Transient Aircrews are not expected to hold onto the material for an extended period of time, and therefore there is no need for the same level of accountability as with other entities such as NATO Forces or the Base COMSEC Account itself.

AFCOMSEC Form 16 inventories are retained for the current inventory plus the previous 6 months of inventory. This means that the form includes information on the current inventory as well as the inventory from the past 6 months. This allows for a comprehensive record of inventory to be kept and helps in tracking any changes or discrepancies over time.

It is recommended to change a cipher lock combination at least once a month to ensure maximum security. Regularly changing the combination reduces the risk of unauthorized access as it limits the time frame for someone to potentially figure out the current combination. This frequent change also prevents any potential security breaches or compromises that may occur over a longer period of time.

The destruction certificates are filed in folder 6 of the COMSEC account 6-part folder.

The main goal of buffers is to temporarily hold data used by some types of hardware. Buffers act as a temporary storage area that allows for smoother data flow between different components of a system. By temporarily holding data, buffers can help prevent data loss or corruption when there is a difference in the speed at which data is produced and consumed. This ensures that data is available when needed and can be processed at a consistent rate, improving overall system performance.

A parity bit is a simple error detecting code that is commonly used in data communication. It is a single bit added to a binary code to ensure that the total number of 1s in the code is either even or odd. The receiver can then check the parity bit to detect if any errors occurred during transmission. If the number of 1s is different from what the parity bit indicates, an error is detected. Therefore, the parity bit is a very simple example of an error detecting code.

After the BIOS message appears on the monitor, the next step in the boot up process is usually a memory test being visible on the monitor. This test checks the computer's RAM (Random Access Memory) to ensure that it is functioning properly. It is an important step in the boot up process as it helps identify any potential issues with the computer's memory.

ALC-2 is the correct answer because it indicates that the COMSEC material is accounted for continuously by quantity. The other accounting legend codes (ALC-1, ALC-3, and ALC-4) do not specify continuous accounting by quantity.

The correct answer is ALC-4. This COMSEC material is not required to be tracked on the daily or shift inventory. This suggests that ALC-4 is either not considered as important or its tracking is not necessary for the daily or shift operations.

In the preparation phase, the COMSEC manager assesses the specific materials needed by the CRO officer. This involves identifying the necessary encryption devices, codes, keys, and other resources required for secure communication. By determining these materials in advance, the COMSEC manager ensures that the CRO officer is properly equipped to protect sensitive information during communication operations.

In the distribution phase, the CRO checks the material issued against the list on the SF 153. This phase involves the actual transfer of materials from one location to another, ensuring that the correct items are being distributed according to the list provided. The CRO plays a crucial role in verifying that the materials being distributed match the list on the SF 153, ensuring accuracy and accountability in the distribution process.

ICAP is known as a suite of modules and accessory kits that serve as the backbone of deployed communication networks.
