Integrity constraints are enforced by The database designer.
<h3>What are Integrity constraints?</h3>
An Integrity Constraints is known to be the protocols that a table's data columns is mandated to follow.
Note that they are used to hinder the types of information that can be put into a table and as such, Integrity constraints are enforced by The database designer.

Some computer engineering students decided to revise the LC-3 for their senior project. KBSR and the DSR into one status register: the IOSR (the input/output status register). IOSR[15] is the keyboard device Ready bit and IOSR[14] is the display device Ready bit can be done in LC-3.
LC-4 is a poor design.
Explanation:
LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.
It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a theoretically viable target for a C compiler. The language is less complex than x86 assembly but has many features similar to those in more complex languages. These features make it useful for beginning instruction, so it is most often used to teach fundamentals of programming and computer architecture to computer science and computer engineering students.
The LC-3 specifies a word size of 16 bits for its registers and uses a 16-bit addressable memory with a 216-location address space. The register file contains eight registers, referred to by number as R0 through R7. All of the registers are general-purpose in that they may be freely used by any of the instructions that can write to the register file, but in some contexts (such as translating from C code to LC-3 assembly) some of the registers are used for special purposes.
When a character is typed:
- Its ASCII code is placed in bits [7:0] of KBDR (bits [15:8] are always zero)
- The “ready bit” (KBSR[15]) is set to one
- Keyboard is disabled -- any typed characters will be ignored
When KBDR is read:
- KBSR[15] is set to zero
- Keyboard is enabled
- Alternative implementation: buffering keyboard input

Answer:
The host-based firewall settings are blocking the service
Explanation:
Host-based firewall settings can be configured on each workstation. The firewall can be provided by the operating system itself, or it can be a standalone software package that provides security features and functionality for the device's network connection. If this firewall contains incorrect settings, legitimate services can be blocked, and if so, a message will usually notify the user of such a breach. In these cases, the firewall settings need to be adjusted to make the desired service work.
