Process synchronization-oocomputerworld


Process synchronization:- Process synchronization is the task coordinating the execution of process in a way that no two process can have excess to the same shared data and resources it is specially needed in multi process system when multiple process are running together and more than one process try to gain access to the same shared resources or data at the same time this can lead to inconsistency of shared data, So the changes made by one process note necessary reflected when other processes access the same shared data. To avoid the this type of inconsistency of data, the process need to be synchronize with each other. When two or more process operated with each other, their order of execution must be preserved otherwise there can be conflicts in their execution and in appropriate output can be produced. A Co-operative process is the one other one which can affect the execution of other process or can be affected by execution of other processes. 


Such process need to be synchronized so that their order to execution can be granted.

Single partition allocation, Multiple-partition allocation and Fixed Equal-size partitions in operating system-computer world

  Single partition allocation, Multiple-partition allocation and Fixed Equal-size partitions in operating system Single partition allocation In this scheme operating system is residing in law memory and user process are executing in higher memory. Advantages It is simple  It is easy to understand and use Disadvantages User job is limited to the size of available memory. It leads to poor Utilization of processor and memory. Multiple-partition allocation  It is the simplest method for allocating  memory is divided memory into several fixed size partitions. Fixed Equal-size partitions It divides the main memory Into equal number of fixed sized partitions, operating system occupies some fixed portion and remaining portion of main memory is available for user processes. Advantages It supports multi programming. A process whose size is less then or equal to the partitions size can be loaded into any available partition. Disadvantages If a program is big to fit in...

Memory in computer (primary, secondary and cache memory)-computer world

  Memory : A memory just like a human brain.It is used to store data and instructions. Computer memory is the storage space in the computer, where data is to be processed and instruction  required processing are stored. Computer memory is classified into following types : 1. Cache memory : Cache memory is a very high speed semiconductor memory which can speed up the CPU. It act as buffer(small storage are ) Between the CPU and main memory. We can say that it is a high speed memory between CPU and RAM and it is used temporary store very active data and instruction during processing.  2. Primary memory : Primary holds only that data and instruction on which the computer is currently working. Data holds by primary memory is lost when power is switched of. Primary is not fast as resisters. Primary is divided into two subcategory's : 1. RAM(Random access memory) : Random access memory is a form of computer memory that can be read and change in any any order typically ...

Definition of computer cables and types of cables

Definition of computer cables and types of cables Definition  of computer cables : A cable is one or more wires which are covered in plastic that transmitter power or data between devices and computers. A cables is also known as cord, connector or plug. Data cables provides communication between devices for example DVD and HDMI, USB cables and Cat 5. A power cable is used for supply the power and electricity. Types of cables : There are many types of cables used in computer science some of them are given below : Coaxial cable Twisted cable Optical cable Coaxial cable :   It is consist of a central copper wire surrounded  by a copper mess.  Coaxial cables are used for transmitting data at high rate. Coaxial tables are used by telephone companies to transmit data because cables handle  up to 40000 telephone calls simultaneously. Coaxial  cables group of specially wrapped and insulated wires.   Twisted pair cab...
