Colour coding is a method of organizing and identifying items based on specific colours assigned to different categories or characteristics.

• Used in various industries for organization and identification purposes

• Commonly used in electronics for identifying components (e.g. resistors, capacitors)

• Helps improve efficiency and reduce errors in tasks that involve sorting or categorizing items

RAM stands for Random Access Memory, a type of computer memory that can be accessed randomly; it is volatile and temporary.

• RAM is a type of computer memory that stores data and machine code currently being used by the CPU.

• It is volatile, meaning it loses its data when the computer is turned off.

• RAM is faster to read from and write to than other types of storage like hard drives.

• Examples of RAM include DDR4, DDR3, and L

BSOD stands for Blue Screen of Death, a Windows operating system error screen displayed when a system encounters a critical error.

• BSOD is a screen displayed by Microsoft Windows when the system encounters a critical error that it cannot recover from.

• It usually includes an error code and information about the error that caused the system to crash.

• BSOD can be caused by hardware failures, software issues, or driver proble...read more

A network is a collection of computers, servers, mainframes, network devices, and other devices connected to one another to share data and resources.

• Networks can be wired or wireless

• They can be local (LAN), wide area (WAN), or global (Internet)

• Networks use protocols like TCP/IP to facilitate communication

• Examples include Ethernet, Wi-Fi, and cellular networks

The pattern of a pyramid is a geometric shape with a polygonal base and triangular faces that converge to a single point at the top.

• Pyramids have a base that can be any polygon, such as a square or a triangle.

• The faces of a pyramid are triangular in shape and meet at a single point called the apex.

• Pyramids are commonly found in architecture, such as the Egyptian pyramids or the pyramids of Mesoamerica.

Active Directory is a directory service developed by Microsoft for Windows domain networks.

• Centralized database for managing network resources

• Stores information about users, computers, and other network objects

• Allows administrators to control access and permissions

• Facilitates single sign-on for users across different applications and services

An IP address is a unique numerical label assigned to each device connected to a computer network.

• IP addresses are used to identify and locate devices on a network.

• There are two types of IP addresses: IPv4 (e.g. 192.168.1.1) and IPv6 (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

• IP addresses can be static (manually assigned) or dynamic (assigned by a DHCP server).
