In an asynchronous write, the data are stored in the cache, and control returns to the caller.
An asynchronous write is a write operation that does not block the caller until the data is actually written to the underlying storage. The data is instead stored in the cache, and control returns to the caller. When the data is eventually written to the underlying storage, the write is said to be "completed".
Asynchronous writes can be useful in situations where blocking the caller is not desirable, or where the time to complete the write is not known in advance. For example, an application that is writing data to a slow storage device may choose to use an asynchronous write in order to avoid blocking the caller while the data is being written.

If an ip address has the number 194 in the first octet, it is a class _______ address.
If an IP address has the number 194 in the first octet, it is a class C address.
If you're working with IP addresses, it's important to know the different classes. An IP address can be classified as a Class A, B, or C address. If the first octet of an IP address is 1-126, it's a Class A address. If the first octet is 127, it's a Class B address. And if the first octet is 128-191, it's a Class C address.
The number in the first octet tells us what class the address is in. For example, an address with the first octet of 194 is a Class C address. Class C addresses are most commonly used for home and small office networks.
Knowing the class of an IP address is important because it determines the range of addresses that can be used. For example, Class A addresses can be used for networks with up to 16 million hosts, while Class B addresses can be used for networks with up to 65,000 hosts.
So, when you're working with IP addresses, be sure to keep the different classes in mind. Knowing which class an address is in will help you understand what range of addresses can be used.

Size vs capacity the netvidsdatabase class had two methods called size and capacity. what is the difference between size and capacity?
The NetvidsDatabase class is a data structure that stores information about movies. The size of the NetvidsDatabase represents how many movies are currently in the database, while the capacity represents how many movies can be stored in the database before the underlying array needs to be expanded.
When the NetvidsDatabase is first created, its size and capacity are both set to 0. As movies are added to the database, the size is incremented. If the size reaches the capacity, then the capacity is doubled and the underlying array is expanded to accommodate the new movies.
The NetvidsDatabase class is an efficient way to store and manage information about movies. The size and capacity parameters help to ensure that the underlying array does not need to be frequently expanded, which can save time and resources.
