Answer:
Hardware security module.
Explanation:
Hardware security module is a Physical digital device that comes as a plug-in adapter used to secure and manage digital keys and provides crypto processing for strong authentication.
It has an onboard cryptographic keyboard and one or more crypto processors, and can be used on computers and network servers to prevent logical or physical authentication access to unauthorized users. It supports symmetric and asymmetric cryptography.
Answer:
The data in web storage is passed to the server with every HTTP request.
Explanation:
There are basically two Web storage APIs Session storage and local storage.Both can store data up to 5MB. They are supported by every modern browser.You can store data in local storage indefinitely and for browser session in session storage.There is no data or information in HTTP request header.So we conclude that option 4 is the answer.
Answer and Explanation:
Given that total number of records in a file = 100000
Each record consists of= 240 bytes
Given that B= 2400 bytes.
Then total blocks in file = 100000 records * 240 / 2400
= 10000 blocks.
Time that will take for exhaustive read
= s + r + b.btt
= 16 + 8.3 + (10000) * 0.8
= 8024.3 msec
Now as per given X be the number of records that are searched randomly and it takes more than exhaustive read time.
Hence, X (s + r + btt) > 8024.3
X (16+8.3+0.8) > 8024.3
X > 8024.3/25.1
So that, X > 319.69
Hence, atleast 320 random reads should be made to search the file
The correct answer is known as a "query".
When you ask a lot of complex questions , which uses comparison operators, that is called a query. A query refers to the <span>exact request for </span>data retrieval<span> with the use of database and information systems. </span>
