Answer:

RAID level 5 can be used to compensate a limited number of available disks.

Explanation:

There are two type of RAID

  • Hardware RAID

Software RAID

deliver services form the host.

Hardware RAID

RAID has levels

0, 1, 5, 6, and 10

4 and 6 also work on both media.

RAID 0 :Striping

In this level minimum of two disks,RAID 0 split the file strip the data.Multiple hard drive are used to split the data.

RAID 1 : Mirroring

In this level Minimum two disk require and provide data tendency.

RAID 5 :Stripping with parity

Parity is a binary data.RAID system calculate the value which system used to recover the data.

Most RAID system with parity function store parity blocks.

RAID 5 combines the performance of RAID 0 with redundancy of RAID 1.

What are computer virus ? Explain in detail.In your answer include symptoms and prevention (3each)
Elenna [48]

Answer:

Explanation:

A computer virus is a form of malicious software that piggybacks onto legitimate application code in order to spread and reproduce itself.

Like other types of malware, a virus is deployed by attackers to damage or take control of a computer. Its name comes from the method by which it infects its targets. A biological virus like HIV or the flu cannot reproduce on its own; it needs to hijack a cell to do that work for it, wreaking havoc on the infected organism in the process. Similarly, a computer virus isn't itself a standalone program. It's a code snippet that inserts itself into some other application. When that application runs, it executes the virus code, with results that range from the irritating to the disastrous.

Computer virus symptoms

How can you tell if a virus has slipped past your defenses? With some exceptions, like ransomware, viruses are not keen to alert you that they've compromised your computer. Just as a biological virus wants to keep its host alive so it can continue to use it as a vehicle to reproduce and spread, so too does a computer virus attempt to do its damage in the background while your computer still limps along. But there are ways to tell that you've been infected. Norton has a good list; symptoms include:

Unusually slow performance

Frequent crashes

Unknown or unfamiliar programs that start up when you turn on your computer

Mass emails being sent from your email account

Changes to your homepage or passwords

Do the following SQL questions. The resulting columns must all have descriptive names. You must show the result of the query. Fo
Maslowich

Answer:

We can use CREATE command to create tables with columns having descriptive names

Explanation:

Firstly, create a table using CREATE  command in SQL. The syntax is as follows:

CREATE TABLE [table_name]

(

 [col_name] [datatype]),

[col_name] [datatype]),

[col_name] [datatype]),

[col_name] [datatype])

)

Once the table is created, we can insert the data into table using INSERT command. It's syntax is as follows:

INSERT INTO table_name VALUES('', '', '')

if datatype is string, values must be entered within single quotes. If datatype is int, values are entered directly without using  quotes.

Now, you can select the data from  the table using SELECT command. It's syntax is as follows:

SELECT column-list FROM table_name

If you want to filter rows according to conditions, you can use WHERE command.

I have created  sample table and inserted some data into it. Now, I applied some queries on it to select data from the table.

I have written in a text file and attached the same. Please find. Thank you!
