Q281.
How does the processor predict the outcome of a conditional branch?

a.

By waiting for information on the branch's outcome before fetching the next instruction

b.

By assuming that backward branches are always taken and forward branches are not taken

c.

By using a branch trace buffer to record the results of recent branch instructions

d.

By refilling the pipeline with instructions from the branch's target address

Discuss
Answer: (b).By assuming that backward branches are always taken and forward branches are not taken Explanation:The general prediction strategy is to assume that backward branches are always taken and forward branches are not taken, and that IA-32 processors use a branch trace buffer to record the results of recent branch instructions.
Q282.
What is the purpose of the double-speed ALUs in the IA-32 architecture?

a.

To perform floating-point operations

b.

To move data between memory and the FPU stack

c.

To execute two operations in a single clock cycle

d.

To reorder ΞΌops based on resource availability

Discuss
Answer: (c).To execute two operations in a single clock cycle Explanation:Port 0 and port 1 both have double-speed ALUs (arithmetic logical units). This is a significant aspect of IA-32 optimizations because it means that each ALU can actually perform two operations in a single clock cycle.
Q283.
What is object-oriented design (OOD)?

a.

The process of designing a program using objects

b.

The process of designing a program using procedures

c.

The process of designing a program using static libraries

d.

The process of designing a program using dynamic libraries

Discuss
Answer: (a).The process of designing a program using objects Explanation:Object-oriented design (OOD) is the process of designing a program using objects.
Q284.
What is assembly language?

a.

A high-level programming language

b.

A low-level programming language

c.

A markup language

d.

A scripting language

Discuss
Answer: (b).A low-level programming language Explanation:Assembly language is a low-level programming language that is used to write programs that can be executed by a computer. It is a symbolic representation of the machine code instructions that the computer can understand.
Q285.
What is a compiler?

a.

A program that takes a high-level representation of a program as input and produces a different representation of the same program as output.

b.

A program that converts machine code to assembly language.

c.

A program that converts assembly language to high-level language.

d.

A program that translates one programming language to another.

Discuss
Answer: (a).A program that takes a high-level representation of a program as input and produces a different representation of the same program as output. Explanation:A compiler takes a high-level representation of a program as input and produces a different representation of the same program as output.
Q286.
What is a virtual machine?

a.

A software environment that directly runs on a processor

b.

A hardware component that executes programs on the local processor

c.

An intermediate representation of a program's bytecode

d.

None of the above

Discuss
Answer: (c).An intermediate representation of a program's bytecode Explanation:Some software development platforms generate some kind of intermediate representation of the program, or bytecode. This bytecode is then read by a special program on the user’s machine, which executes the program on the local processor. This program is called a virtual machine.
Q287.
What is a virtual machine?

a.

A type of microprocessor

b.

A program that generates machine code

c.

A processor-specific environment that runs programs

d.

A software environment that reads intermediate bytecode and executes programs

Discuss
Answer: (d).A software environment that reads intermediate bytecode and executes programs Explanation:A virtual machine is a software environment that reads intermediate bytecode and executes programs. This means that a virtual machine is not a microprocessor (option a) or a program that generates machine code (option b). It is also not necessarily processor-specific (option c), as some bytecode formats have multiple virtual machines that allow running the same bytecode program on different platforms.
Q288.
What are two common virtual machine architectures?

a.

Microsoft .NET and Adobe Flash

b.

Java Virtual Machine and Common Language Runtime

c.

Oracle Database and MySQL

d.

Amazon Web Services and Microsoft Azure

Discuss
Answer: (b).Java Virtual Machine and Common Language Runtime Explanation:Some software development platforms generate an intermediate representation of the program or bytecode, which is then read by a special program on the user's machine, known as a virtual machine. Two common virtual machine architectures are the Java Virtual Machine that runs Java programs and the Common Language Runtime that runs Microsoft .NET applications. Option a) is incorrect as Adobe Flash is not a virtual machine architecture, and option c) and d) are incorrect as Oracle Database, MySQL, Amazon Web Services, and Microsoft Azure are not virtual machine architectures either.
Q289.
What is bytecode?

a.

A low-level language similar to assembly language

b.

A high-level language used in virtual machines

c.

A programming language used for web development

d.

A type of binary code used by hardware processors

Discuss
Answer: (a).A low-level language similar to assembly language Explanation:Bytecode is a low-level language similar to hardware processor's assembly language, used by virtual machines to execute programs.
Q290.
What is an interpreter?

a.

A program that reads a program's bytecode executable and executes it in a virtual environment

b.

A program that deciphers source code and generates machine code

c.

A program that manages memory allocation and deallocation

d.

A program that executes machine code directly on the host CPU

Discuss
Answer: (a).A program that reads a program's bytecode executable and executes it in a virtual environment Explanation:An interpreter is a program that reads a program's bytecode executable and executes it in a virtual environment implemented in software.
