Port 993 is used for secure IMAP (Internet Message Access Protocol) connections. IMAP allows email clients to access email messages stored on a mail server. Port 993 specifically designates IMAP over SSL/TLS (IMAPS), which encrypts the communication between the email client and the server, ensuring data confidentiality and integrity during transmission. Port 993 and port … Read more
IMAP4 (Internet Message Access Protocol version 4) is a protocol used by email clients to retrieve email messages from a mail server. It allows users to manage their email messages on the server without having to download them to their local devices permanently. IMAP4 supports functionalities such as folder management, message flagging, and synchronization of … Read more
IMAP (Internet Message Access Protocol) is a protocol used by email clients to retrieve and manage email messages stored on a mail server. Unlike POP3 (Post Office Protocol version 3), which typically downloads emails to a local device and removes them from the server, IMAP allows users to view, organize, and synchronize their emails across … Read more
Post Office Protocol (POP) has two main modes of operation: POP3 (Post Office Protocol version 3) and POP2 (Post Office Protocol version 2). POP2 was the earlier version of the protocol and is less commonly used today. It retrieves emails from a server to a client device, deleting them from the server once downloaded. POP3, … Read more

SMTP is responsible for sending outgoing email messages from a sender’s email client or server to the recipient’s email server. It operates on port 25 (or port 587 for … Read more
The function of the NTP (Network Time Protocol) protocol is to synchronize the time of computer systems over a network. It ensures that all devices within a network agree on the current time, which is crucial for maintaining consistency in operations, logging events accurately, and coordinating tasks that require synchronized timing across distributed systems. NTP … Read more
Zigbee is a wireless communication protocol designed for low-power, low-data-rate applications such as wireless sensor networks and Internet of Things (IoT) devices. It operates on the IEEE 802.15.4 standard and uses the 2.4 GHz frequency band (in most regions) for communication. Zigbee forms a mesh network where devices can communicate directly with each other or … Read more
A server plays a crucial role in computing by providing centralized resources and services to client computers or devices within a network. It is a dedicated computer or software system designed to respond to requests from clients and facilitate data sharing, communication, and resource management. Servers are typically more powerful and equipped with specialized hardware … Read more
LLDP (Link Layer Discovery Protocol) and CDP (Cisco Discovery Protocol) are both protocols used for network device discovery and management, but they differ in their implementations and vendor support. LLDP is an open standard protocol defined by the IEEE (Institute of Electrical and Electronics Engineers) and is vendor-neutral, making it compatible with devices from various … Read more
There are three main types of servers: file servers, which store and manage files accessible to network users; application servers, which host and deliver applications to client computers or devices over a network; and database servers, which manage and store databases, allowing clients to retrieve and manipulate data. Servers can be categorized into various types … Read more
