What are the three basic types of instruction?

The three basic types of instruction are as follows:

1. Imperative Instruction: This type of instruction involves giving commands and providing details about how the task should be carried out. This type of instruction typically signals specifics about the task—what should be done, in what order, and how long it should take to complete the task.

2. Declarative Instruction: This type of instruction involves providing information and the details of a task that the learner may need to know. The goal is to provide all the facts and information required to understand, remember, and be able to apply the given task.

3. Procedural Instruction: This type of instruction is focused on instructing and providing steps, guidance, and strategies to complete a task. It is selective as it focuses more on concepts, principles, and how to transfer knowledge rather than the facts.

This type of instruction helps learners to develop skills they can use while carrying out tasks.

How many types of instruction are there?

There are five main types of instruction, which are as follows:

1. Imperative: This type of instruction involves giving specific commands and instructions for a task. It is typically used for giving instructions for tasks that need to be performed quickly or precisely.

2. Descriptive: This type of instruction involves providing an explanation of how something is done. It is typically used for providing instructions for tasks that involve more complex concepts or information.

3. Procedural: This type of instruction involves providing step-by-step instructions on how to complete a task. It is typically used for providing instructions for tasks that involve multiple steps and processes.

4. Directive: This type of instruction involves providing advice, guidelines, and suggestions on how to complete a task. It is typically used for providing instructions for tasks that involve more subjective matters.

5. Explanatory: This type of instruction involves providing an analysis of why things are done the way they are. It is typically used for providing instructions for tasks that involve advanced concepts, such as in mathematics or science.

What are 3 instructions a teacher might give?

1. Listen carefully to the instructions: It is important for students to listen carefully to the instructions given by their teacher. Make sure all students are paying attention and understand what is being asked of them before starting the task.

2. Raise your hand before asking a question: Encourage students to raise their hand if they have a question or need clarification on something. This ensures that all the students in the classroom are paying attention and will not disrupt the lesson or disturb other students.

3. Stay on task: Make sure that students remain focused and pay attention throughout the lesson. Distractions like talking to peers or using phones should not be allowed and students should be reminded to stay on task and complete their work.

What is 3 address instruction advantages and disadvantages?

The 3-address instruction is an instruction which uses three memory locations (or registers) to store information. This type of instruction has some advantages as well as some disadvantages.

Advantages:

1. The 3-address instruction allows for a more efficient use of memory by requiring fewer instructions to achieve a given result. This leads to shorter programs that can be executed faster and take less memory space.

2. It also helps to simplify expression evaluation and result calculation as it eliminates the need for temporary variables which can add complexity.

3. The 3-address instruction allows for more flexibility and increased scope of operations, making it possible to manipulate greater amounts of data in a single instruction.

4. The 3-address instruction also enables a reduction in execution time as the machine does not have to process all of the data at once but instead processes sections at a time.

Disadvantages:

1. The 3-address instruction can lead to increased overhead as the machine has to execute multiple instructions to get the desired result.

2. It can also require multiple operation cycles as the machine must load, decode, and execute a large number of instructions.

3. The 3-address instruction can be hard to debug as the operation performed by a single instruction may be difficult to understand.

4. The 3-address instruction can also be difficult to optimize as there may not be any known optimizations that can be applied to improve the performance of the instruction.

What is addressing mode and define 2 addressing modes with an example each?

Addressing mode is the strategy used by a processor to determine how the memory address of an instruction or the data is identified. With the two basic addressing modes, the processor can determine both where the instruction is located in memory and what data the instruction will operate upon.

The two primary addressing modes are:

1. Immediate Addressing Mode: In immediate addressing mode, the processor directly obtains the memory address of the operand from the instruction. For example, if the instruction is MOV AX, 23h, the processor will directly take the 23h (data) and store it in the AX register.

2. Direct Addressing Mode: In direct addressing mode, the memory address of the operand is stored within the instruction. For example, if the instruction is MOV AX, [100], the processor first reads the memory address 100h, and then reads the data from the memory address and stores it in the AX register.

Which of the following is a 2 word instruction set *?

The most common 2-word instruction set is “fetch execute,” which is used in processor architectures. This two-word instruction set instructs the processor to retrieve an instruction from memory and then execute it.

This is the basis for most computer programs, as they are largely made up of processors fetching, decoding, and executing instructions in sequence. Additionally, this two-word instruction set can also be used to instruct the processor to perform arithmetic and logical operations such as addition and subtraction, as well as branching and conditional execution.

What is Thumb 2 instruction?

Thumb 2 instruction is a 32-bit instruction set used in modern ARM CPUs. It was introduced in 2007 and is one of the components of the ARMv7 architecture. Thumb 2 allows code to be written in a more compact instruction set and provides increased speed and performance compared to previous designs.

It also enables more efficient use of code size and power while offering improved performance over ARMv5 and ARMv6 architectures. The main benefit of Thumb 2 is its ability to allow better use of computer memory, providing a smaller and more efficient code than what could be achieved using the ARMv6 instruction set.

With improved performance and decreased instruction set size, Thumb 2 increases power efficiency and stability for applications like embedded systems, audio and video applications, and more.
