1 Define the two main categories of processor registers?
User-visible registers: Enable the machine- or assembly-language programmer to minimize main memory references by optimizing register use.Control and status registers: Used by the processor to control the operation of the processor and by privileged, operating system routines to control the execution of programs.
How many types of registers?
registers are five types.
A RISC computer has 16 global registers 10 windows 16 local registers per window and 16 common registers per window What is the window size and total number of registers?
304
Why Encapsulation is an important concept in the context of Object Orientation?
From the point of view of security and robustness it is important for the program code in a class that instantiates an object not to be necessarily visible to the programmer and never visible to the user.
How many register are located in 8088microprocessor?
there are 14 registers in 8088 micro processor. All the 14 are 16 bit registers. They are4 segment registers viz - code segment register, stack segment register, data segment register, extra segment register.general registers are - accumulator register i.e. AX, base register i.e. BX, count register i.e. CX, data register i.e. DX and stack pointer (SP), base pointer (BP).index registers are - source index(SI), destination index(DI),and the other registers are instruction pointer and flags register.
User visible register?
Registers that are used during prigramming and specified directly by the instruction.
What categories of data are commonly supported by user-visible register?
User-visible registers commonly support several categories of data, including general-purpose data for arithmetic and logic operations, control and status information, and memory addresses for data manipulation. They may also include special-purpose registers for specific functions like instruction pointers or stack pointers. Additionally, some architectures provide registers for floating-point operations and SIMD (Single Instruction, Multiple Data) processing. Overall, user-visible registers facilitate efficient data handling and processing within the CPU.
What is a program visible register?
the registers that are used during programming and are specified directly by the instructions.

What is program-visible registers?
Program-visible registers are a set of registers in a CPU that can be accessed and manipulated directly by software programs. These registers typically store data, addresses, or control information that the program needs during execution. Their visibility allows for efficient data handling and faster execution, as operations can be performed directly using these registers rather than accessing slower memory. In contrast, some registers are internal or reserved for the processor's own operations and are not directly accessible by programs.

Which color registers the highest frequency shortest wave length?
Of the visible light spectrum, that would be blue light.

What are the Differences between program invisible registers and program visible registers?
The programming model of the 8086 through the Pentium II’s considered to be program visible because its registers are used during application programming and are specified by the instructions. Other registers, detailed later in this chapter, are considered to be program invisible because they are not addressable directly during applications programming, but may be used indirectly during system programming. Only the 80286 and above contain the program-invisible registers used to control and operate the protected memory system.
What are the 4 general purposes registers?
Cash register School Register -------------------- processor register User-accessible Registers Data registers Address registers Conditional registers General purpose registers Floating point registers Constant registers Special purpose registers Instruction registers Model-specific registers Control and status registers Memory buffer register Memory data register Memory address register Memory Type Range Registers Hardware registers
What is difference between enable and visible property in visual basic?
Visible means that the property can be used, but is not visible in the graphical user interface. But, if the user were to click a control that edit the objects properties, the object would change even if it isn't visible. Enabled/Disable means that for instance if the object is Disabled, it's still visible but the user cannot interact with it. This means, that if code is executed for the control that is disabled, nothing will change to that control.
Which color registers the highest frequencyshortest wave length?
In visible light, that would be blue light. But please note that there are also higher frequencies, not visible for the naked eye - ultraviolet, x-rays, gamma rays.
