When computing a bootstrap confidence interval for a parameter, at least how many times should we re-sample from the original sample?.
Bootstrap - There is no definitive answer to this question, but a common rule of thumb is to resample at least 1000 times.
What is Bootstrap?
An HTML, CSS, and JS library called Bootstrap aims to make the creation of educational web pages as simple as possible (as opposed to web apps). The main goal of adding to a web project would be to apply the colour, size, font, and layout options of Bootstrap to that project. Therefore, the main determinant is whether the responsible developers like those options. All HTML components have basic style declarations once Bootstrap is introduced to a project. As a result, texts, tables, and form components appear consistently in all web browsers. In order to further personalise the appearance of their contents, developers can make use of the CSS classes defined in Bootstrap.

assuming that inputfile is a scanner object used to read words from a text file, select an expression to complete the following code segment, which counts the number of words in the input file.
A Scanner object may read a text file. Utilizing the methods included with the Scanner class is a benefit of utilizing the Scanner.
To guarantee that the file is closed, the application should define the Print Writer variable in a try-with-resources statement. Leading and trailing spaces are removed by the built-in Java String function trim(). The space character's Unicode value is "u0020." Java's trim() function looks for this Unicode value before and after the text, removes any spaces if they are present, and then returns the string that was omitted. The exception produced inside the try block will be propagated up the call stack if it occurs both inside the try-with-resources block and when a resource is closed (when close() is used).

suppose that a 64-bit processor uses the following cache: 2kb block size, 16-way associativity, and total size of 32mb. determine how many bits are used for the tag, index, and block offset.
We are aware that 64 KB equals 64K words, or 2 to the power of 14 words (2 to the power of 1 word = 2 to the power of 14 blocks).
Each block has 32 bits of data, a 32-14-2 bit tag, and a valid bit. Therefore, for a 64-KB cache, the overall cache size is (2 to the power 14)*49=784 bits, or 98KB. Since there are 64 bytes per line and a cache line's size equals a main memory block's size, the block offset is 6 bits. Associative 2-way cache stores two lines as a single set. The remaining 18 bits for the tag are calculated as follows: number of sets = total cache lines/2 = (512KB/64)/2 = 212, translating to 12 bits for the set.

What is IP address?
An Internet Protocol address (IP address) is a numerical label that identifies a computer network that employs the Internet Protocol for communication. An example of such an IP address is 192.0.2.1.Identification of the network interface and location addressing are the two primary purposes of an IP address. A 32-bit number is what the Internet Protocol version 4 (IPv4) designates as an IP address. However, a new version of IP (IPv6), utilising 128 bits again for IP address, was established in 1998 in response to the expansion of the Internet and the exhaustion of IPv4 addresses. Deployment of IPv6 has been happening since the middle of the 2000s.
