Year 8 Computer architecture (unit 8)

A program written in __________ needs to be ____________ to ___________.

• source code, translated, machine code

• machine code, programmed, source code

• source code, programmed, machine code

• machine code, encrypted, source code.

The fetch _______ execute cycle is a sequence of actions the CPU performs to execute each machine code instruction in a program.

• reboot

• initiate

• store

• decode

A computer architecture where data and program instructions are stored in the same memory location.

• Harvard architecture.

• Von Neumann architecture.

• Caltech architecture.

• Van Helsing architecture.

Which of the following is a disadvantage of the Von Neumann architecture?

• Data and program instructions both use the same bus, which is slow, so the CPU spends too much time waiting for instructions.

• The program counter can only function if the electrical pathway to the register is clear.

• There is a flaw in the design which can cause humans to become irradiated.

• The integrated development environment only allows a small set of data holding places.

Which of the following is not normally included in an integrated development environment?

• Debugging facilities

• Interpreters

• Compilers

• Integrated circuits

__________ convert assembly languages into object code. The object code is then output by the assembler, and linked to together to form machine code.

• Compliers

• Assemblers

• Interpreters

• Object codes

Interpreters....

• convert assembly languages into object code. The object code is then output by the assembler and linked together to form machine code.

• are designed for rapid access by the CPU when processing. They consist of enormous numbers of memory cells.

• take each line of code written in a high-level programming language such as PHP one at a time and convert it into an intermediate language, before converting it into machine code.

• Take a high level programming language like C, and translate it into object code, which is created in the form of an executable file. The object code is linked together to form machine code in the form of an executable file.
