In summary, a branch instruction is conditional and will jump to a different location if a certain condition is met. A jump, on the other hand, is not conditional and will always jump to a specific location. The usage of these instructions can vary depending on the programming language being used.

how is "branch" instruction different from "jump"?

Thanks in advance.

A branch instruction is conditional. If some condition is met, program flow jumps to some other location. If the condition is not met, the next instruction is executed instead.

A jump, on the other hand, is not conditional.

It also sometimes has to do with language you are programming. I believed in 68HC11 code, a jump is for an absolute position, and a branch is relative. Check out the BRA and the JMP commands.

From what I have seen, it is more loose than an absolute definition.

ya, we use 68HC12. Thanks for the explanations.
 

1. What is the purpose of instructions in a computer?

Instructions in a computer are a set of commands that tell the computer what to do. They are essential for the computer to perform tasks and carry out operations.

2. How are instructions stored in a computer?

Instructions are stored in the computer's memory in the form of binary code, which is a series of 0s and 1s. Each instruction is represented by a unique binary sequence.

3. Can instructions be modified or changed?

Yes, instructions can be modified or changed by programmers or users. This allows for the computer to perform different tasks and adapt to different situations.

4. Are all instructions in a computer the same?

No, instructions in a computer can vary depending on the type of processor and its architecture. Different processors may have different instruction sets and may require specific instructions to perform certain tasks.

5. How does a computer execute instructions?

A computer executes instructions in a sequential manner, one after the other. The processor reads the instructions from memory, decodes them, and then executes them. This process is repeated until all instructions have been executed or until a program is terminated.
