Silicon is the basic element in computer microchips. This is because silicon has unique electrical properties that make it an ideal material for creating transistors, which are the building blocks of microchips. Silicon is a semiconductor, meaning it can conduct electricity under certain conditions. It is abundant, relatively inexpensive, and can be easily processed into wafers, making it the preferred material for manufacturing microchips. Additionally, silicon has a high melting point and is chemically stable, which allows microchips to operate at high temperatures without degrading.

The CPU, or Central Processing Unit, is the heart of the entire computer complex data processing system. It is responsible for executing instructions and performing calculations, making it a crucial component in processing and managing data. The CPU acts as the brain of the computer, coordinating and controlling the various operations of the system. Without the CPU, the computer would not be able to perform any tasks or process any data, making it the central component in the data processing system.

The avionics control unit responsible for performing trajectory impact calculations to determine the weapon release point is the Weapons delivery control unit. This unit is specifically designed to calculate and determine the optimal point for releasing weapons during an operation or mission. It takes into account various factors such as aircraft speed, altitude, target location, and other critical data to ensure accurate weapon delivery and maximum effectiveness.

The clock controls the speed of a computer's activities. The clock is an electronic component that generates a regular pulse or signal, known as clock cycles, which synchronize the operations of the computer's components. It determines the rate at which instructions are executed and data is processed. The clock speed is measured in hertz (Hz) and a higher clock speed generally results in faster processing and execution of tasks.

Auxiliary storage in a computer refers to memory stored outside the computer. This means that it is additional storage that is not directly connected to the computer's main storage or memory. Auxiliary storage can include devices such as external hard drives, USB flash drives, and cloud storage services. These external storage options provide extra space for storing data that is not immediately needed by the computer's processor, allowing for the storage of large amounts of data that can be accessed when required.

AND gate is the correct answer because it is a logic gate that produces a high output only when both of its inputs are high. In other words, it sends a pulse only when it receives a pulse at both its terminals.

The offensive systems operator is provided with a video display of various important data such as navigation, countermeasure, stores management system, and system management data. This display is known as the multifunction display. It allows the operator to access and monitor multiple functions and systems simultaneously, providing a comprehensive view of the offensive systems and their status. This helps the operator effectively manage and control the offensive systems during operations.

The avionics control unit complex supports the function of weapons delivery. This means that it is responsible for controlling and managing the delivery of weapons on the aircraft. It ensures that the weapons are deployed accurately and effectively, allowing the aircraft to engage targets and carry out its mission.

The avionics control units do not have a print controller. A print controller is a device that manages the printing process, but it is not necessary for the functioning of avionics control units. These units are responsible for controlling and monitoring various electronic systems in an aircraft and do not require printing capabilities.

ROM stands for Read-Only Memory, which is a type of primary memory in a computer complex that cannot be erased or modified. It contains permanent instructions and data that are stored during manufacturing and cannot be changed by normal computer operations. ROM retains its contents even when the computer is powered off, making it non-volatile. This makes it ideal for storing firmware and other critical system information that needs to be accessed quickly and reliably. Therefore, ROM is the correct answer for the primary memory that usually cannot be erased in a computer complex.

The correct answer is "displaying information in the form of printed characters." This is because using a text-based method means representing information on a computer display using characters that resemble printed text. This method is commonly used in command line interfaces and text editors where text is displayed as a series of characters rather than graphical objects or images.

Passive and active are the two ways in which fine synchronization is accomplished. Passive synchronization refers to the process of synchronizing with an external time source without actively transmitting any signals. This can be done by receiving signals from GPS satellites or other timekeeping devices. Active synchronization, on the other hand, involves actively transmitting signals to synchronize with other devices or systems. This can be done through the use of network protocols or specialized synchronization hardware. Both passive and active synchronization methods are commonly used in various industries and applications to ensure accurate and precise timing.

Microprocessors are chips with circuits that are capable of performing the functions of all the different parts of a computer. They are essentially the "brain" of a computer, responsible for executing instructions, performing calculations, and controlling the overall operation of the system. Microprocessors are commonly used in various electronic devices, including computers, smartphones, and tablets, due to their compact size and high processing power.

The two non-central avionics control units are responsible for terrain following and radar control. These functions are crucial for the safe navigation and operation of the aircraft. Terrain following ensures that the aircraft maintains a safe altitude above the ground, especially during low visibility conditions or when flying over uneven terrain. Radar control involves the management and operation of the aircraft's radar system, which is used for detecting and tracking other aircraft, as well as for navigation and situational awareness. These functions are essential for the overall performance and safety of the aircraft.

When you slide the real beam map switch on the tracking handle backwards, the ranges that are stepped through are 160, 80, 40, 20, and 10.

When all of the avionics control unit's power lights are off and you press one of the ACU/PWR ON switchlights, you cause power to be applied to the four central avionics control units. This means that pressing the switchlight will activate the power supply to the four central avionics control units, allowing them to receive power and function properly.

The Tactical Digital Information Link J performs 77,000 hops per second to preclude jamming by a narrow band jammer. This means that the link changes its frequency rapidly, making it difficult for the jammer to disrupt the communication. By hopping between different frequencies, the link can avoid interference and maintain a reliable connection.

The operating band used by the Joint Tactical Information Distribution System is L.

The arithmetic/logic unit of a computer stores the intermediate results of arithmetic operations in registers. Registers are small, high-speed storage units located within the CPU. They are used to hold data that is being actively used or manipulated by the CPU. Since registers are located within the CPU itself, they allow for fast access and retrieval of data, making them ideal for storing intermediate results during arithmetic operations.

If the critical data avionics control unit (ACU) is not available when one of the other ACUs fail, the ACU complex powers off automatically and the mission is aborted. This means that without the critical data ACU, the system cannot continue processing the necessary functions to carry out the mission successfully, leading to an automatic shutdown and the termination of the mission.

The correct answer is "Twelve blocks displayed in four levels of video intensity." This means that on the multifunction displays, there are twelve blocks that are shown, and each block is displayed in one of four different levels of video intensity. This test pattern helps to assess the functionality and performance of the displays by checking if all blocks are visible and if the video intensity levels are accurate.

The correct answer, "X HAIR X HAIR TO," suggests that this bomb/navigation control switchlight command is responsible for directing the crosshairs to a selected action point.

Nickel-cadmium batteries are used as the power source to provide emergency back-up power to the Joint Tactical Information Distribution System terminal. These batteries are known for their high energy density, long cycle life, and ability to withstand extreme temperatures. They are commonly used in critical applications where reliability and longevity are crucial, making them an ideal choice for maintaining critical data during emergencies.

Random access memory (RAM) is a type of computer memory that allows data to be read from and written to in any order, making it suitable for storing the results of computer calculations. Unlike other types of memory, RAM is volatile, meaning that its contents are lost when the computer is powered off. Therefore, it is commonly used to temporarily store data that needs to be quickly accessed and manipulated by the computer's processor during calculations or program execution. RAM provides fast and efficient storage for these results, allowing for efficient computation and data processing.

A video graphics array (VGA) computer monitor typically has 640 pixels per horizontal line. This resolution is a standard for VGA monitors and provides a decent level of detail for most computer applications.

The correct answer is mass storage device. Each central avionics control unit can be loaded from a mass storage device. This suggests that the avionics control unit can retrieve or access information from a storage device, such as a hard drive or memory card, which contains the necessary data or software required for its operation. This allows for flexibility and ease of updating or changing the information on the avionics control unit as needed.

The Joint Tactical Information Distribution System/Multifunctional Information Distribution System terminal provides for the transmission and reception of Tactical Digital Information Link (TADIL) J information.

The data buses used in the ACU complex are 1553B.

When the mass storage device is initially loaded or reloaded, the display electronics unit provides the inputs. As a result, the avionics control units are automatically declared unloaded. This means that the avionics control units are not operational or active until they are specifically loaded. Therefore, in order to ensure proper functioning of the avionics control units, they must be loaded first before any other systems or components can be activated.

The correct answer is "crosshair control" because it suggests that the movement of the tracking handle crosshair is controlled by a specific mechanism or feature called "crosshair control." This implies that there is a dedicated control system or function in place to manipulate the crosshair's movements, making it the most logical choice among the given options.

The power output of the high power amplifier group in high power mode is 1050 watts.

The correct answer is Satellite communication/Global Positioning System antenna. This component enables beyond line of sight coverage by utilizing satellite communication technology and the Global Positioning System. It allows for communication and positioning information to be transmitted and received over long distances, even when there are obstacles or no direct line of sight between the sender and receiver.

The radar data terminal operates in conjunction with the terrain following ACU. This suggests that the radar data terminal is specifically designed to work together with the terrain following ACU, indicating that they have a close relationship and likely depend on each other for effective operation. This could mean that the radar data terminal provides data or information to the terrain following ACU, or that it receives and processes data from the terrain following ACU.

The correct answer is "Mass storage device". A mass storage device is a type of storage that provides bulk storage for programs and database information to be transferred to and from the memories of each of the ACUs (Avionics Control Units). This device allows for the storage and retrieval of large amounts of data, making it suitable for storing programs and database information in an efficient and organized manner.

When an unacknowledged subsystem message is available, the subsystem indicator appears in reverse video on the multifunction display. This means that the indicator will be displayed with the colors inverted, usually with a dark background and light text. This visual cue helps to draw attention to the unacknowledged message and indicates that action needs to be taken to address the issue.

The correct answer is 960-1215 MHz. This range represents the frequencies that the low pass filter allows to pass through. A low pass filter is designed to allow signals with frequencies below a certain cutoff frequency to pass through, while attenuating or blocking signals with higher frequencies. In this case, the low pass filter allows signals in the range of 960-1215 MHz to pass through, while attenuating or blocking signals with frequencies above this range.

The data bus that is part of the avionics multiplex data buses is A.

The data rates used in a stacked net of Tactical Digital Information Link (TADIL) J voice channels are 2.4 or 16 kb per second.

The LRU (Last-Resort Unit) is a backup for the mass storage device known as the Data Transfer Set. It is responsible for transferring data between different devices or systems. In case of a failure or malfunction of the primary mass storage device, the LRU can take over and ensure that data transfer operations can still be carried out effectively.

Link 16 friendly status reports provide information about the equipment status. This means that the reports contain details about the operational status, availability, and condition of the equipment being monitored. It allows for effective communication and coordination between friendly forces by providing real-time updates on the status of equipment, ensuring that all parties involved are aware of any potential issues or limitations.

The correct answer is Navigation/auxiliary. This control allows the offensive system operator to apply or remove power from the avionics control unit complex, giving them control over the navigation and auxiliary systems.

The integrated keyboard allows the offensive system operator to select between multifunction displays.

The correct answer is "terrain following ACU". The radar set is managed by the terrain following ACU, which suggests that this unit is responsible for controlling and operating the radar system. The terrain following ACU is specifically designed to provide accurate terrain mapping and navigation information to the aircraft, allowing it to fly at low altitudes and follow the contours of the terrain. This functionality is crucial for missions that require precise navigation and avoidance of obstacles, such as low-level flying or terrain-hugging maneuvers.

The correct answer is impedance matching and transformer coupling. Impedance matching ensures that the input and output impedances of the data link terminals are matched, allowing for efficient transfer of signals. Transformer coupling is a method of connecting the terminals using transformers, which provide electrical isolation and allow for signal transmission between different impedance levels. This combination of impedance matching and transformer coupling ensures proper signal transmission and compatibility between the data link terminals.

When in the display mode, pressing the NEXT switch on the integrated keyboard displays the option set. This means that pressing the NEXT switch will show a list of available options or choices that the user can select from. This allows the user to navigate through different settings or actions that can be performed in the display mode.

The control unit in a computer acts like a sophisticated switchboard operator. It is responsible for coordinating and controlling the activities of other components in the computer. Similar to a switchboard operator, the control unit receives and interprets instructions from the memory, and then directs the flow of data and instructions to the appropriate components, such as the arithmetic unit and logic unit. It ensures that the instructions are executed in the correct sequence and coordinates the timing of operations. In this way, the control unit plays a crucial role in managing the overall operation of the computer system.

During load management mode 2, the powered data transfer set cavities are 1 and 2.

The correct answer is 930 bits. In a given time slot of a Joint Tactical Information Distribution System, the maximum amount of data that can be transmitted is 930 bits. This indicates that the system has the capacity to handle and transmit a larger amount of data compared to the other options provided (465 bits, 516 bits, and 258 bits).

The synchronization process can be initiated every 12 seconds when a Net Entry message is transmitted. This means that the synchronization process occurs periodically, specifically every 12 seconds, whenever a Net Entry message is sent. This ensures that the system remains synchronized and updated at regular intervals.

The control panel backup feature for the integrated keyboard can simulate a digital signal. This means that it can replicate a signal that has discrete values, typically represented as a series of 0s and 1s. Digital signals are commonly used in computer systems and electronic devices as they are more reliable and less susceptible to noise interference compared to analog signals. The control panel backup feature allows for the simulation of such digital signals, enabling testing and troubleshooting in various applications.
