Answer:

11: Compiler translates a high level source program into a target equivalent (machine language).

An interpreter implements a virtual machine, the high-level programming language of which is the "machine language." The interpreter reads statements more or less one at a time in that language, and executes them as they go along.

12: One could also consider Java either. A compiler (complicated translator) can create code, which is then executed by a complicated virtual machine (interpreter)

13: A preprocessor is an initial translator which removes comments and white space, and group characters together into tokens such as keywords, identifiers, numbers, and symbols, as well as simple syntactic structure analyses. A compiler uses in-depth analysis and nontrivial transformation.

14: C++ implementations based on the early AT&T compiler created an intermediate program in C rather than assembly language

15: Stack-based language, similar to modern Java compiler byte code

16: A method in which a simple interpreter implementation evolves into building more complex versions until the compiler is built.

17: A compiler which translates byte code into machine language immediately prior to each program execution.

18: Lisp and Prolog

19: TEX and TROFF are one of such compilers that translate high-level document descriptions into laser printer or phototypesetter commands. Query language processors for database systems are also compilers that translate languages such as SQL into primitive file operations.

21: without havin to call multiple tools with command-line tools, You can write an entire program in an IDE.

The text discusses three approaches to combining overall cost leadership and differentiation competitive advantages. Which of th
dedylja [7]

Answer:

C. deriving benefits from highly focused and high technology markets

Explanation:

Firms that engage in cost-leadership approach seek to combine a low per-unit income with large sales for profit making purposes. Typically, but not always, they are more inclined to market their products and services to a large population base or a niche with a high demand volume. While differentiation enables a company to accomplish a competitive advantage. A Competitive advantage enables a company to achieve more strides over other companies offering related product substitutes. It is an important marketing process that is of critical economic importance to a business.

It should be noted that deriving benefits from highly focused and high technology markets is not part of the approaches to combining overall cost leadership and differentiation competitive advantages.

On the 80x86 CPU, the ESP register keeps track of the value on the top of the runtime stack.
Ronch [10]

Answer:

True

Explanation:

The ESP register acts as an indirect operand pointing to the top of the stack at any time.

Stack grows downwards from high memory when a program adds to the stack. However, when items are removed from the stack, it shrinks upwards from low to high memory.

The assembler reduces the stack pointer(ESP) register by 2, when a word value is pushed on to the stack. On the other hand, the assembler increases the stack pointer by 2 when a word value is popped off.

The assembler decreases or increases the ESP register by 4 when a double word value is pushed or popped off the stack respectively. Therefore the ESP register changes in multiples of 4.
