To remove files, use the rm command. The rm command also prompts before deleting folders when the -i and -r arguments are used combined.
The final flag supplied takes effect if both -i and -f are specified. To do this, we enter the desired working directory's pathname after typing cd. A pathname is the path we take through the tree's branches to reach the desired directory. Absolute pathnames and relative pathnames are the two ways that pathnames can be given. Let's start by taking a look at absolute pathnames. Use the rm command along with the recursive option, -r, to delete a directory along with all of its contents, including any subdirectories and files.

consider a source and destination host. before packets leave the source host, the host needs to define the path over which the packets will travel to reach the destination host. false
Before packets leave the source host, the source host does not define the path over which the packets will be traveling to reach the destination host. Thus the given statement is false.
When packets are transmitted over the network from a source host to a destination host, the source host does not determine the path through which packets will travel toward the destination host from the source host. Instead, it is the router that defines the best path and directs the packets from the source host to the destination host.
What is a router?
A router is a network layer device that determines the optimal path along which packets are forwarded over the network. Based on network layer information, routers forward packets from one network to the other network.

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.

The client will attempt to establish a TCP connection with the incorrect process or a nonexistent process if you use different port numbers. There will be errors.
An internet message or other network communication that arrives at a server can be redirected to a specific process by using the port number. All network-connected devices have standardized ports with a unique number installed. Multiple connections can be accepted simultaneously by a single listening port. There is a restriction of 64K that is frequently mentioned, but it should be made clear that this applies to each client and each server port.

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.
