Answer:
1). Serial ATA (SATA): SATA drives are base hard drives. Serial ATA was designed to replace the older parallel ATA (PATA) standard (often called by the old name IDE), offering several advantages over the older interface: reduced cable size and cost (7 conductors instead of 40), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through a I/O queuing protocol. On some systems without a controller, these can be cabled instead to the onboard SATA connections on the motherboard. On smaller servers with a controller, they can still be cabled because these systems will not have a backplane. Cabled hard drives are not hot swappable.
2). Near Line SAS: Near Line SAS are enterprise SATA drives with a SAS interface, head, media, and rotational speed of traditional enterprise-class SATA drives with the fully capable SAS interface typical for classic SAS
drives. This provides better performance and reliability over SATA. Basically it is a hybrid between SATA and SAS.
3). Serial Attached SCSI (SAS): SAS is a communication protocol used in Enterprise hard drives and tape drives. SAS is a point-to-point serial protocol that replaces the older based parallel SCSI bus technology (SCSI). It uses the standard SCSI command set. These have extra connections through the top of the SATA connection. These are the top end in performance for electromechanical drives.
4). Solid-State Drive (SSD): An SSD is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives. SSDs do not employ any moving mechanical components, which distinguishes them from traditional magnetic disks such as hard disk drives, which are electromechanical devices containing spinning disks and movable read/write heads. Compared with electromechanical disks, SSDs are typically less susceptible to physical shock, are silent, and have lower access time and latency. Typically because of these features, SSD drives can be the fastest I/O in the market today in standard hard drive form factor.

Answer:
A milestone is a significant progress point within your project. Milestones' main purpose is to set goals you have to achieve in order to succeed and complete your project
Explanation:
-Example 1-
You have to write a report for your project. This report contains introduction, problem background, results, and recommendations. The milestones for writing your report could be:
Milestone 1: introduction section is completed
Milestone 2: problem background section is completed
Milestone 3: results section is completed
Milestone 4: recommendations section is completed
-Example 2-
You have to design a webpage that allows the user to login, enters his/her name, and logout. The milestones in this case could be:
Milestone 1: login functionality is completed
Milestone 2: text field for typing the name is placed
Milestone 3: submit name button functionality is completed
Milestone 4: logout button functionality is completed
Milestone 5: all components of the webpage are fully integrated
You might think the goals in these examples can be set differently, and that is true. The definition of the milestones is in general subjective and it depends on how you design the steps you want to follow to complete your project. You might also want to add these milestones to a timeline so you have an estimated schedule of the development of your project.
Answer:
D
Explanation:
A is declaring a variable
B is getting input from the user and storing it in variable age
C is outputting the word "age" to the screen
D is outputting the word "age" to the screen and then outputting the value of the age variable immediately after which is correct.
Answer: C. Interface.
Explanation:
File manager is an interface between the hardware part of a computer and the software. the main function of a file manager is to help the user manage all files which they have stored up on their computers. for example the file managers allows the users to view, copy, delete and edit the files which they have stored up on their computer storage devices.
