The name of the Windows boot loader program for a BIOS system is called the Master Boot Record (MBR).
This program is responsible for locating the bootable partition on the hard drive and loading the operating system into memory. The MBR is stored in the first sector of the hard drive and contains information about the partition table, boot sector, and the boot loader code.
On the other hand, the name of the Windows boot loader program for a UEFI system is called the UEFI boot manager. This program replaces the MBR and works differently from the traditional BIOS system.
Instead of using a boot sector to load the operating system, UEFI systems use a boot partition that contains the boot loader program.
The UEFI boot manager is responsible for locating and launching the boot loader program, which then loads the operating system into memory.
UEFI systems provide several advantages over traditional BIOS systems, such as faster boot times, improved security features, and support for larger hard drives.

the following code causes java to throw ________. int number = integer.max_value + 1;
The following code causes Java to throw an ArithmeticException.
This is because the code attempts to store a value in the variable 'number' that exceeds the maximum weight that an integer data type can represent. In Java, the integer data type has a maximum value of 2,147,483,647 ([tex]2^{31}[/tex] - 1) and a minimum value of -2,147,483,648 (-[tex]2^{31}[/tex]). If a value is assigned to an integer variable that exceeds these limits, an ArithmeticException is thrown.
In this particular case, the code is attempting to store the value of an integer.max_value + 1 in the 'number' variable. Since integer.max_value already represents the maximum value that can be stored in an integer variable, adding 1 to it will cause it to exceed this limit and result in an ArithmeticException being thrown.
To avoid this exception, it is important to ensure that any values assigned to integer variables do not exceed the maximum or minimum values that can be represented by the data type. This can be done by using appropriate range checks and data validation techniques.

False. Broadcast TV reaches its audience through the transmission of radio waves, not through wires. These signals are picked up by antennas on television sets or by cable providers, but they do not rely on wires strung from telephone poles or laid underground.
Broadcast television uses a network of transmitters to send signals over the air, which can be picked up by antennas connected to television sets. While some cable television providers do use wires to deliver TV signals to households, this is not considered broadcast TV. Broadcast TV is typically free to access with an antenna and does not require a subscription to a cable or satellite provider. This is different from cable or satellite television, which relies on wired connections, such as coaxial cables, fiber-optic cables, or satellite dishes, to deliver content to subscribers. Broadcast TV is designed for free over-the-air reception, and while it may have a more limited channel selection than cable or satellite services, it remains an important medium for reaching audiences, particularly in rural or remote areas where wired connections may not be available.

a ____ is equal to exactly 1,024 bytes, but often is rounded down to 1,000 bytes by computer users.
A kilobyte (KB) is equal to exactly 1,024 bytes but is often rounded down to 1,000 bytes by computer users. This approximation occurs because people tend to use a base 10 (decimal) numbering system, which simplifies calculations by using multiples of 10.
However, computers operate using a binary (base 2) system, and memory capacities are measured in powers of 2. The discrepancy between the two systems results in the rounding of 1,024 bytes down to 1,000 bytes. Technically, 1,024 bytes is the accurate measurement of a kilobyte, as it is a multiple of 2^10. In contrast, 1,000 bytes is a multiple of 10^3, which aligns with the decimal system.
This rounding can sometimes cause confusion when comparing file sizes or data storage capacities. To address this issue, the International Electrotechnical Commission (IEC) introduced the term "kibibyte" (KiB) to represent 1,024 bytes, while "kilobyte" (KB) remains for 1,000 bytes. However, the usage of kibibyte has not been widely adopted, and kilobyte still frequently refers to both 1,000 and 1,024 bytes in common practice.
