Which of these generally leaves messages on a mail server?
- A.
IMAP4
- B.
SMTP
- C.
POP3
- D.
HTTP
Correct Answer
A. IMAP4Explanation
IMAP4 generally leaves messages on a mail server. IMAP4 (Internet Message Access Protocol version 4) is a protocol used by email clients to retrieve emails from a mail server. Unlike POP3 (Post Office Protocol version 3) which typically downloads emails to the client device and removes them from the server, IMAP4 allows users to access and manage their emails directly on the server. This means that messages are stored on the server and can be accessed from multiple devices, providing a more synchronized and flexible email experience. SMTP (Simple Mail Transfer Protocol) is used for sending emails, while HTTP (Hypertext Transfer Protocol) is used for web browsing.Rate this question:

Correct Answer(s)
A. Complex instruction set computer (CISC)
B. Reduced instruction set computer (RISC)
C. Explicitly parallel instruction computing (EPIC)Explanation
The main categories of instruction sets are Complex instruction set computer (CISC), Reduced instruction set computer (RISC), and Explicitly parallel instruction computing (EPIC). These categories represent different approaches to designing the instruction set architecture for a computer processor. CISC focuses on providing a wide variety of complex instructions that can perform multiple operations in a single instruction. RISC, on the other hand, emphasizes a simplified instruction set with a smaller number of basic instructions that can be executed more quickly. EPIC is a newer approach that aims to exploit parallelism in instruction execution by allowing multiple instructions to be executed simultaneously. EISC is not a main category of instruction sets and is therefore not included in the correct answer.Rate this question:
