Q. How are the instructions executed and interpreted?
All computers have a Unit which performs arithmetic and logical functions. This Unit is called as Arithmetic and Logic Unit (ALU). However how will computer decide what operation is to be carried out by ALU or we can say who will interpret the operation that is to be performed by ALU?
This interpretation is carried out by Control Unit of computer. The control unit recognizes the binary form of instruction as well as interprets instruction to generate control signals. These control signals then direct ALU to carry out a particular arithmetic or logic function on data. Thus by changing control signal desired function can be performed on data. Or on the other hand the operations that require to be performed on the data can be achieved by providing a set of control signals. So for a new operation one just needs to change set of control signals.
The unit which interprets a code (a machine instruction) to produce respective control signals is called as Control Unit (CU). A program comprises a sequence of codes. Every code is, in effect, an instruction for computer. The hardware interprets each one of these instructions and then generates respective control signals such that desired operation is performed on data.
The Control Unit (CU) and Arithmetic Logic Unit (ALU) together are termed as Central Processing Unit (CPU). CPU is the most significant component of a computer's hardware.
All these arithmetic and logical Operations are carried out in CPU in some special storage areas known as registers. Size of the register is one of the significant considerations in signifying processing capabilities of CPU. Register size indicates to the amount of information which can be held in a register at a time for processing. Larger the register size the faster can be the speed of processing.
Question: (a) Program instructions and data are brought into memory first, in order to be executed. Explain how the CPU enables an instruction to be executed? (b) Describe
The idea of clustering is defined as use of multiple computers naturally multiple storage devices, PCs or UNIX workstations and their interconnections to make what emerges to users
A shell is a program that presents an interface to several operating system functions and services. The shell is so called because it is an outer layer of interface among the user
Backward Chaining: In generally given that we are only interested in constructing the path whether we can set our initial state to be the theorem statement and search backward
What are benefits of having densely packed Integrated Circuits? These are stated below: Reliability: The integrated circuit interconnections are in fact more reliable
What is blocking probability? Blocking Probability: The blocking probability P is described as the probability like all the servers in system are busy. If all the servers ar
The OS of a computer might be periodically collect all the free memory space to form contiguous block of free space. Garbage collection
It speeds execution of distributed applications. It runs on dissimilar platforms. It time independent. No loss for msg delivery i.e. guarantee delivery.
What is virtual memory? Method that automatically move program and datablocks into the physical main memory when they are needed for execution are known as virtual memory.
Q. Show the Comparison of ASCII and EBCDIC? EBCDIC is an easier to employ code on punched cards due to BCD compatibility. But ASCII has some of major benefits on EBCDIC. These
