To create an SSL connection, a Web server requires a ________, which is an electronic document that confirms the identity of a w

pogonyaev

Answer:

c. SSL Certificate

Explanation:

The full form of SSL is Secure Sockets Layer. It is the standard security technology which establishes the encrypted link between a client and the server—typically a web server (which is the website) and the browser, or the mail server along with a mail client (for e.g., Outlook).

In the context, in order to develop an SSL connection, an SSL Certificate is required by the Web server.

Provided you have an Internet connection and functional Web browser, gather information on three different commercial RAID contr

aalyn [17]

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.

Since java.util.PriorityQueue doesn't use the Cloneable interface, I think it's safe to say that Serializable interfaces are implemented in all instances.

Given six memory partitions of 300 KB, 600 KB, 350 KB, 200 KB, 750 KB, and 125 KB (in order). The memory allocation algorithm th

Makovka662 [10]

Answer:

The memory allocation algorithm that is used to place the processes given is the <u>First Fit Algorithm </u>

Explanation:

The First Fit Management Algorithm works by ensuring that the pointer keeps track of all the free spaces in the memory and accepts and executes all instructions to allocate a memory block to the coming process as long as it is big enough to hold the size of the process.

For example, the First Fit algorithm will allocate the processes in the first block that fits (that is, if it can fit the memory bock in the queue, then the process will be store)

It will work as follows (recall that the memory partitions are in order and must remain so):

A) 115 KB is stored in 300KB block, leaving the following free spaces (185KB, 600KB, 350KB, 200KB, 750KB, 125KB), next

B) 500 KB is store in a 600KB block leaving the following free spaces (185 KB, 100 KB, 350 KB, 200 KB, 750 KB, 125 KB), next

C) 358 KB is stored in 750KB block, leaving the following free spaces (185KB, 100KB, 350KB, 200KB, 392KB, 125KB) next

D) 200 KB is stored in 350KB block, leaving the following free spaces (185 KB, 100 KB, 150KB, 200KB, 392KB, 125KB) next

E) 375KB is stored in 392KB block leaving (185KB, 100KB, 150KB, 200KB, 17KB, 125KB)

One of the demerits of this Algorithm is that, as shown above, memory is not maximized. It however is one of the easiest algorithms amongst all the other memory allocation processes.
