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.

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...
