Difference Between SATA and PATA
In this post, we will understand the difference between SATA and PATA −PATAIt stands for Parallel Advanced Technology Attachment.It is a 40 pin connector.It is expensive.The speed of data transfer is low.It consumes more power.The size of the cable is big.It doesn’t come with hot swapping feature.External hard drives can’t be used with PATA.SATAIt stands for Serial Advanced Technology Attachment.It is a 7 pin connector.It is cheap.The speed of data transfer is high.It consumes less power.The size of the cable is small.It comes with the hot swapping feature.External hard drives can be used with SATA.
Read MoreDifference Between Internal and External fragmentation
In this post, we will understand the difference between internal and external fragmentation −Internal FragmentationThe difference between the memory allocated and the space required is known as internal fragmentation.In this fragmentation, fixed-sized memory blocks are used to process data.This process occurs when a method or process is larger than the required memory.The method used in internal fragmentation is ‘best-fit’ block.It occurs when the memory is divided into fixed sized partitions.External FragmentationThe unused spaces that is formed between fragments of non-contiguous memory, which are too small to help with a new process, is known as external fragmentation.It uses variable-sized memory blocks ...
Read MoreDifference Between Linker and Loader
In this post, we will understand the difference between a linker and a loader −LinkerThe main function of the linker is to generate executable files.The linker takes the input as the object code which would be generated by a compiler/assembler.The process of linking can be understood as a method to combine different snippets of code in order to obtain executable code.There are two types of linkers available: Linkage Editor and Dynamic Linker.Linker also helps combine all the object modules.Linker is responsible to arrange the objects in the program’s address space.LoaderThe main function of a loader is to load executable files ...
Read MoreDifference between Simultaneous and Hierarchical Access Memory Organisations
As we know in context of computer/system, the main key feature on which the whole performance get dependent is Memory. It is memory and its allocation which make the system to perform fast and efficient. Now on the basis of organizing of this memory in the system, we can distinguish between Simultaneous and Hierarchical Access Memory Organisations.Following are the important differences between Simultaneous and Hierarchical Access Memory Organisations.Sr. No.KeySimultaneous Access Memory OrganisationsHierarchical Access Memory Organisations1DefinitionSimultaneous Access Memory Organisations is the memory organizing technique in which CPU can interact with multiple memory levels at same time and gets data interaction. This ...
Read MoreHow to Increase the Size of a Linux LVM by Adding a New Disk?
This article helps us to add a new disk to LVM ( Logical Volume Manager), the very best advantage of LVM over normal disk partitions is its support for “dynamic partitions”; you can create and resize (expand or shrink) LVM volumes dynamically as we needed. There is no limit of the physical disk boundary in LVM logical volumes, so you can create a large LVM volume that spans across multiple smaller physical disks. This flexibility partitioning allows you to manage storage space more efficiently as disk usage change from time to time.If you want to add new disks to an ...

In this article, we will learn how to enable or add the swap partition on Ubuntu 16.04, actually, the swap will increase the chance of responsiveness of the servers by guarding the out of memory errors for the applications, by default Ubuntu will not enable the swap space. We will learn how to add or enable the swap file for Ubuntu 16.04 servers.Swap is the location or the file which can handle the temporary data which is not required immediately by RAM but will be used to increase the amount of information that the server can handle for its working ...
