what would happen if you delete a game from file explorer instead of the laucher it was downloaded from
If you delete a game from File Explorer instead of the launcher it was downloaded from, the game files will be removed from your computer, making it inaccessible to the launcher.
When you delete a game from File Explorer, you are directly removing the game files from your computer's storage. The launcher, which manages the game installation and updates, relies on these files to run the game. Without the game files, the launcher won't be able to locate the necessary components and won't be able to launch the game.
The game will effectively become inaccessible and unplayable until you reinstall it using the original launcher. Deleting the game through the launcher itself is preferable as it ensures proper removal and prevents any potential issues with the game's installation and associated files.

you design a recursive descent parser for a cfg by writing a parsing function for each nonterminal symbol of that cfg.
To design a recursive descent parser for a Context-Free Grammar (CFG), you write a parsing function for each nonterminal symbol in the CFG.
These parsing functions recursively analyze the input based on the grammar rules associated with the nonterminal symbols.
A recursive descent parser is a top-down parsing technique where the parsing process starts from the start symbol of the CFG and recursively expands nonterminal symbols until the input is fully parsed or an error is encountered. Each nonterminal symbol in the CFG corresponds to a parsing function.
The parsing functions are responsible for recognizing and handling the different grammar rules associated with their respective nonterminal symbols. They typically have a similar structure: they examine the input, apply the corresponding grammar rule, and call other parsing functions to handle the nonterminal symbols in the rule.
The recursive nature of the parser allows it to handle CFGs that exhibit recursive structures, such as nested expressions or repetitive constructs. By recursively calling the parsing functions, the parser explores all possible paths through the grammar to determine the valid structure of the input.
Overall, a recursive descent parser provides a systematic approach to parse input based on a CFG by breaking down the parsing task into smaller subtasks associated with the nonterminal symbols. It offers flexibility and readability in the implementation, making it a popular choice for simple to moderately complex grammars.

how many functional failures can raid 10 withstand and remain functional?
RAID 10 can withstand multiple functional failures and remain functional.
How many functional failures can RAID 10 endure while remaining operational?RAID 10, also known as RAID 1+0 or mirrored striping, offers a high level of fault tolerance by combining mirroring and striping techniques. In this configuration, data is simultaneously written to multiple drives, creating a mirrored set of striped drives. This design allows RAID 10 to withstand the failure of multiple drives within the array and still remain functional.
By implementing RAID 10, you benefit from its ability to withstand the loss of up to half of the drives in the array without losing any data or suffering from a complete system failure.

Not all file systems support setting access control on files or directories. The ability to set access control on files or directories depends on the file system's features and the underlying operating system.
File systems like ext4, NTFS, and HFS+ (used by Linux, Windows, and macOS, respectively) support access control mechanisms that allow setting permissions on files and directories. These permissions determine who can read, write, or execute the file. They are typically represented by the permission bits such as r (read), w (write), and x (execute) in the ls -l output.
However, there are file systems that do not support access control. For example, the FAT file system (commonly used in USB drives and older Windows versions) does not have built-in support for access control. In such cases, the operating system may emulate access control by applying permissions based on the mounted file system's configuration.

_____ encodes a message with an algorithm that uses a single numeric key to encode and decode data.
The answer to your question is that the term you are referring to is "symmetric encryption". Symmetric encryption is a matrix type of encryption where a single key is used to both encrypt and decrypt data.
In a symmetric encryption system, the algorithm used to encrypt the data is known as the "cipher". The cipher takes the original message (plaintext) and the key as input, and produces the encrypted message (ciphertext) as output. To decrypt the ciphertext and recover the original message, the same key is used with the same cipher algorithm.
The use of a single key in symmetric encryption makes it faster and more efficient than asymmetric encryption, which uses two separate keys for encryption and decryption. However, symmetric encryption also presents a security risk, as the key must be kept secret and secure to prevent unauthorized access to the encrypted data.

When a packet arrives at the router, it checks the destination IP address and compares it with its routing table. The routing table contains information about the destination network addresses and the next-hop router that the packet should be forwarded to. The router then selects the best path for the packet based on metrics such as distance, bandwidth, and cost.
The router forwards the packet to the next-hop router, which repeats the process until the packet reaches its final destination. Along the way, each router updates the header of the packet with its own IP address and passes it on to the next router. This process is known as hop-by-hop forwarding.
Routers can also perform other functions, such as packet filtering, network address translation (NAT), and quality of service (QoS) management. Packet filtering involves inspecting the packet header and either allowing or denying the packet based on predetermined rules. NAT allows multiple devices on a private network to share a single public IP address, while QoS ensures that certain types of traffic (e.g. video conferencing ) receive priority over other types of traffic (e.g. file downloads).
