system buses in computer-computer world

 System bus

System buses in computer are use to connect the measure component of a computer system.Information caries by data bus and address bus determine where it should be sent and a control bus to control it's operation. Simply we can say that buses are used in computer to connect it's components and transfer data between them. Buses may be serial or parallel. Parallel buses transfer data across multiple wires and serial buses transmitted data in single wires. System bus is a cable which capable of carrying signals from one place to another place a computer bus can be divided into two different types : Internal and External . 

Internal bus connect the different component inside  the cabin-ate for example CPU and all other components on the motherboard. 

The external bus connect the different external devices peripherals, extension slots, input output codes etc.

Types of bus : 

1. Address bus : A collection of wires used to identify particular information in main memory is called address bus. Address bus is also known as memory bus.

2. Data bus : Lines that carry data to and from memory are called data bus. The main work of the data bus is to carry digital information.

3. Control bus : A control bus is carries the control signal that make sour everything is flowing smoothly from one place to another.

Deadlock in operating system-computer world

  Deadlock in operating system-computer world Deadlock :  In a multi-programming environment, many process may complete for a minute number of resources. A process make a request for a resource and if the resource is not available at that time, the process enter In a waiting state. A waiting state process is never again-able to change state because the resource it has requested is held by other waiting process. This situation is called deadlock. So we can say that a process is said to be deadlock when it is waiting for an event or resources which will never occurs.   so we can say that in this situation none of the process gets executed  since the resource it needs, is held by some other process which is also waits for some other resource to be released.  Let's assume that there are three process P1, P2, p3 and three different resources R1, R2 and R3. R1 is assigned to p1, R2 is assigned to P2 and R3 is assigned to P3.   After somet...

Memory management in operating system-computer world

Memory management in operating system-computer world Memory management :   The function of operating system which manages the memory of a computer for the processing of the program this management is known as memory management. There are several programs that consist in memory, so it became to move programs and data around the memory of a memory management system is the collection of hardware and software procedures for the Managing various program consisting in the memory. Memory management play an important role in operating system to improve the speed speed of the computer system.   Memory management determines how  memory is allocated between the processes,  deciding which gets memory, when they receive it and how much they are allowed. When memory is allocated it determines which memory location will be assigned. Main memory refers to a physical memory that is the internal memory of the computer. Main memory is also known as RAM. The computer is able t...
