High-level languages usually employ one of two types of translators: a compiler or an interpreter. A compiler is a translator that reads your high-level program and converts the entire thing into a working machine language program.
Indicate which is a pre-emptive scheduling algorithm
Round-robin is the preemptive process scheduling algorithm. Each process is provided a fix time to execute, it is called a quantum. Once a process is executed for a given time period, it is preempted and other process executes for a given time period.
Which of the following, is necessary to work on a computer
An operating system is a software program me required to manage and operate a computing device like smart phones, tablets, computers, supercomputers, web servers, cars, network towers, smart watches, etc. It is the operating system that eliminates the need to know coding language to interact with computing devices.
In the case of disk storage, the access time is the average time taken for a disk drive to provide the first byte of data, measured from the time the host issues a read command. To a good approximation, the average access time is the sum of the average seeks time, the command overhead, and the average latency.
Which of the following is not a characteristic of a daisy chaining priority control scheme?
In computing, a programmable interrupt controller (PIC) is an integrated circuit that helps a microprocessor (or CPU) handle interrupt requests (IRQ) coming from multiple different sources (like external I/O devices) which may occur simultaneously.
An assembler is a program that takes basic computer instructions and converts them into a pattern of bits that the computer's processor can use to perform its basic operations. Some people call these instructions assembler language and others use the term assembly language.
Indicate which, of the following, in not true about an interpreter
Interpreter does not take up the whole of the source code and goes on converting it into the object code. It basically works on a single instruction at a time and translates it first, and then it proceeds further with the next instruction.
Object modules generated by assemblers that contain unresolved external references are resolved for two or more object modules by a/an
In computing, a linker or link editor is a computer system program that takes one or more object files (generated by a compiler or an assembler) and combines them into a single executable file, library file, or another "object" file.
The advantage of a command processor running only built-in commands is:
