Partition Hard disk drive

Hard Disk Partitioning

Disk Partitioning is dividing hard disk drive into multiple disks to treat one large physical disk drive as if it were multiple disks.

Advantages of Disk Partition:

1. Use of multi-boot setups, which allows to have and operate more than one operating system on a single computer.
2. The access time with smaller file systems is efficient when compared to big Master File System with a single Master File Table(MFT).

How to Partition Hard disk drive step-by-step process

Step 1:  Go to START and right click on Computer and select Manage.
Step 2:
1. A window similar to the below one opens, select Disk Management on the left side of the window toolbar.
2. Select the hard disk (C in this case) you want to partition.
3. Right click as shown on the hard drive (c).
4. Select Shrink Volume.

Step 3:
Enter the amount you want to shrink in MB (Example: if you want to partition 100GB from the hard drive, enter the amount to shrink as 102400 MB since 1GB = 1024 MB) and click Shrink.

Step 4:
After the hard disk had partitioned, we need to label that. Right click on the partitioned hard drive to select New Simple Volume.

Step 5: New Simple Volume wizard opens
1. Click Next and specify Volume size and Click Next.
2. Assign Drive Letter or Path(here you can select any letter you want)
3. Format Partition, where you can specify Volume Label (ie., name the partitioned hard disk space).

Once you click Finish, the hard disk is partitioned and labelled.

VMware Workstation

What is a Virtual Machine:

A Virtual Machine, is a computer software implementation of hardware in which you can install an  operating system(OS) that executes programs, applications and scripts just like the real machine do.

VMware:

VMware provides users to set/simulate  a group of computers in order to test software or applications prior to deployment in a known environment.

VMware in Software Testing:

Quality Assurance Teams use VMware Workstation to test applications/software on a variety of operating systems(OS), application platforms and browsers with different configurations of tasks.

Difference between VMware Player and VMware Workstation:

VMware Player is like a subset of VMware Workstation.

1. The major difference is in the previous versions(versions earlier than 3) of VMware Player, you can only run virtual machines created on other versions like VMware Workstation but you cannot create a virtual machine itself. But the newer Versions of VMware Player has the ability to create Virtual machine but the major difference would be VMware Player is available for free while the VMware Workstation costs.
2. In VMware Workstation, you can create multiple snapshots and Clones which helps in case of failures from software or hardware. That is this feature enables users  to create a base VM and Clone it and use it for other software installations and test applications and if there is any kind of crash or system failure you still have your base VMware Workstation. VMware Player is lacking this feature of creating Clones and multiple snapshots.
3. VMware Workstation has the ability to create and manage teams by grouping them while VMware Player is lacking this feature. By grouping multiple VM s into teams, certain operations can be performed on all the members of the team as if it is one machine.
4.  VMware Workstation has the ability to handle VRM(Virtual Rights Management) while the VMware Player does not.

Project Life Cycle (PLC) and System Development Life Cycle (SDLC)

Project Life Cycle (PLC) and System Development Life Cycle (SDLC)

The Project Life Cycle (PLC) focuses on the phases, processes, tools, knowledge and skills for managing a project.

The Systems Development Life Cycle (SDLC) focuses on  creating and implementing the project’s product or the application.

SDLC is a part of PLC, as many of the development activities happen during the execution phase of the PLC.
