DEFINITION
The default port number for HTTP (Hypertext Transfer Protocol)
traffic is port 80. It is the standard port used for transmitting
web pages and other data on the World Wide Web.
SSH is a cryptographic network protocol used to securely
communicate and exchange data between two devices
over an unsecured network. It provides a secure channel
over an insecure network by encrypting the communication
session, allowing users to remotely access and manage
devices securely.
LDAP is an open, vendor-neutral protocol used for accessing
and maintaining directory services data. It provides a
standardized way for querying and modifying directory
services, such as user authentication information,
organizational data, and system configurations.
Common symptoms of a faulty computer system may
include slow performance, frequent crashes or freezes,
unusual noises (such as clicking or grinding), hardware
component failures (such as a malfunctioning hard drive or
RAM), overheating, and error messages during startup or
operation.

The first step in diagnosing a faulty network connection is to
check the physical connections, including cables,
connectors, and network devices (such as routers or
switches), to ensure everything is properly connected and
powered on. Additionally, checking for any network-related
error messages or status indicators on devices can help
identify potential issues
Computer maintenance tips include regularly updating
software and operating systems to patch security
vulnerabilities and improve performance, running antivirus
and antimalware scans to detect and remove threats,
regularly backing up important data to prevent data loss in
case of hardware failure or malware attacks, cleaning dust
and debris from hardware components to prevent
overheating, and avoiding exposure to extreme
temperatures or moisture.
The booting process, also known as bootstrapping or booting
up, is the sequence of events that occur when a computer
system is powered on or restarted. It involves loading and
initializing the operating system and essential system software
from non-volatile storage (such as a hard drive or SSD) into
memory (RAM), configuring hardware devices, and
preparing the system for user interaction. The booting
process typically includes a power-on self-test (POST),
bootloader execution, kernel loading, and initialization of
system services and drivers.
