IMAP is a protocol used by email clients to retrieve emails from a mail server. Unlike POP (Post Office Protocol), which downloads the email and usually removes it from the server, IMAP allows the email to remain on the server while providing access to it across multiple devices. This is particularly useful when users access their email from multiple locations, such as a phone, laptop, and desktop, because any actions performed on the email (such as reading, deleting, or moving) are synchronized across all devices. IMAP essentially keeps a copy of the email on the server, allowing for better flexibility in managing emails.

22.
In the computer memory hierarchy, which is the fastest memory type?
Hide Answer
Answer:
Cache
Explanation:
Cache memory is the fastest type of memory in a computer and is used to store frequently accessed data and instructions. Cache is located close to the CPU, either directly on the processor (L1 cache) or on the motherboard (L2/L3 cache). The speed of cache memory allows the CPU to access data much more quickly than if it had to retrieve it from the main memory (RAM). Cache is particularly useful for speeding up repetitive tasks because it keeps recently used data close at hand. However, it is small in size compared to RAM, so it is used only for critical data that needs to be accessed quickly.

What is the purpose of DNS in the internet structure?
Hide Answer
Answer:
Translate Domain Names
Explanation:
The Domain Name System (DNS) is the technology that translates human-readable domain names, such as www.example.com, into the numerical IP addresses that computers use to identify each other on the network. DNS is often compared to a phonebook because it allows users to access websites using easy-to-remember names instead of complicated numerical addresses. Without DNS, users would have to remember the exact IP address of every website they wanted to visit. The DNS system is distributed globally, with many DNS servers working together to provide quick and reliable access to websites.
