Register and type of register in computer Architecture-computer world

 Register and type of register in computer Architecture


Register : register is very fast computer memory used to store data in execution. A register is consist of a group of flip-flop and gates. The flip flop hold the binary information and gates control when and how new information is transferred into a register.

Types of register 

  1. Input/output adders register
  2. Input/output buffer register
  3. Program counter(PC)
  4. Data register
  5. Accumulator register(AC)

Input/output address register : Each input/output device connector to our computer is mapped to a unique input/output address. These address are assigned to every input/output port on our computer. Including USB, Ethernet as well as any other ports or computer might having a unique address assign to each port allow our computer to easily recognize and locate device attache to computer. 

Input/output buffer register : This register is used for exchanging the data between the input/output module and the processor. 

Program counter (PC) : This register is used for hold the address of instruction and execute these instruction at current time.

Data register (DR) : Data register is used by the microcomputers for storing the data temporary the trans-meted to and from peripheral devices.

Accumulator register(AC) : Accumulator register is used for store Arithmetic and logic data in a computer CPU.

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...

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...

What is computer and its characteristics-computer world

  What is computer and its characteristics  Computer  :  Computer is an electronic data processing device, which accept and store data input, process the data and generates the output in a required format. computer is made up of integrated  parts (input, control, ALU, storage and output unit) All the part work together to process data so, we can say that a computer is a programmable electronic device accept row data as input and process it with  set of instruction to produce the result as output. Meaning of computer The word "computer" comes from the word "compute" which means to "calculate". The word computer is derived from the Latin word compute which means to calculate. Characteristics of computer Automatic : It is a automatic machine work by itself without human instruction. Speed :  A computer is a very fast devices. It can perform in a few second, the amount of work that a human being can do in an entire year.  Accuracy : In addition t...
