Device management in operating system-computer world

 Device management in operating system

Device management in operating system implies the management of input/output devices such as keyboard, disc ,microphone, scanner etc. There are a variety of input output devices that can be attached to a computer system. We discuss about the element of input output devices and how they interact with the computer system and also discuss about the responsibilities of an operating system. Computer operates on many devices like transmission devices, character devices, multimedia devices etc.

Device management is the process of managing the maintenance of physical and virtual devices. The various resources controlled by the operating system can be thought of as devices some of these devices are physical devices and virtual devices, physical devices like keyboard printer Mouse etc Virtual devices like file and device driver. 

Device driver : A device driver is a type of software that helps to run any hardware connected to a computer. When we add a device such as a printer, scanner etc to the computer they also have their driver. Some computers already have a driver and some have to do letter.

Devices management functions that must be performed by an operating system : 

  1. Status of every devices.
  2. Allocate the devices.
  3. keeps tracks of all devices, program responsible for this task is known as input output controller.

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...

Aggregation and Functional dependency in DBMS-computer world

  Aggregation and  Functional dependency in  DBMS Aggregation  In aggregation the relation between two entities is treated as a single entity. In aggregation relationship with its corresponding entity is aggregated into higher level entity . It is the process of compiling information on object, there by obstructing a higher level. On limitation of the ER model is that it can not Express relationship among relationships. The aggregation represent a relationship between a whole object and its component in other word we can say that using aggregation we can express relationship main relationships.  For example center entity offer the course entity act as a single entity in the relationship which is in a relationship with another entity visitor. In the real world if a visitor visits a coaching center they will never inquiry about the course or just about the center instead he will ask the inquiry about both. Functional dependency  Functional dependency play an ...

HTML sites will be show upon client side Technologies, while  DHTML site will be fast enough upon client side Technologies as most of entries are checked on browser itself and not waste time rendering to server for mistake.  HTML creates a plain web page without any style and scripts called as HTML. Whereas,  DHTML creates a page with HTML, CSS,DOM And scripts called as DHTML.  HTML cannot any server side code but XHTML may contain server side code.  ...
