RAM 64 GB

16 GB RAM

Plastic filament

3D printers melt plastic filament to create objects in three dimensions.

Scratched photosensitive drum

Black vertical line runs down the length of the page drum on a laser printer is a critical part of the printing process, and a scratch around the drum will appear as a line down the entire length of the printed page.

VIDEO PCIe graphics adapter

Built-in video adapter

Cooling Liquid-cooled CPU

CPU fan

CIFS

Common internet file system known as SMB (Server Message Block), and it's commonly used on Windows systems for file and printer sharing over tcp/445.

Access Point

Communicate over wireless frequencies An access point provides a bridge between a wired Ethernet network and an 802.11 wireless network.

tcp/23

Connect to a console over an insecure connection Communicating to a command line console on a remote system is commonly performed over tcp/22 using the SSH (Secure Shell) protocol, but older systems may not support the encryption required by SSH.

Firewall

Control the flow of traffic through the network Although a switch or router can be configured with certain traffic control features, the best selection from the available list is a network firewall.

Switch

Forward traffic over the network based on MAC address switch makes all forwarding decisions based on the destination MAC address in the Ethernet frame.

Display High-resolution monitor

Headless

HDMI

High Definition Multimedia Interface External video display video display connection that is used across many different consumer and professional devices.

Ribbion

Impact impact printer uses a print head to physically impact the printed page.

Resource pooling

Individual services are allocated from a larger resource Cloud technologies allow a cloud service provider to create large pools of resources and separate those pools into smaller virtualized groups as needed. This allows the service provider to manage smaller and more powerful groups of hardware devices and separate that hardware into different logical groups.

Ink cartridge

Inkjet placed small drops of ink onto a page, and the printer commonly contains cartridges that store the ink.

IAAS

Internet as a service Hardware is available as an on-demand resource the service provider allocates hardware to be used in the cloud, and it's the responsibility of the customer to install operating systems, applications, and data into the IaaS infrastructure.

SSH

Secure Shell used to communicate to a terminal screen over an encrypted channel using tcp/22.

SLP

Service Location Protocol used to populate the list of available devices on a macOS devices. SLP commonly uses tcp/427 and udp/427.

Hybrid

Services are available publicly on the internet and within a private network.

Rapid elasticity

Services can scale up or down as needed Resource demands can change dramatically depending on the time of day, the season of the year, or an advertising campaign. Rapid elasticity allows the infrastructure to grow and shrink based on these changing demands.

tcp/445

Share a folder in Windows Microsoft Windows uses the SMB (Server Message Block) protocol to transfer files and print jobs between Windows devices. The SMB protocol communicates directly between Windows systems using TCP port 445.

SMTP

Simple mail transfer protocol send messages from a device, or to transfer email messages between email servers over tcp/25.

SNMP

Simple network management protocol used to monitor and configure network devices over udp/161.

Ink cartridge is low

The output prints in the wrong color inkjet printer commonly uses a combination of colors to create the final color output. These colors are often referenced as CMYK (Cyan, Magenta, Yellow, Key or black).

heating element

Thermal Element thermal printer uses a heating element to change the color of specially treated paper.

Fuser is not operational

Toner smears and wipes off the paper the fuser is responsible for applying heat and pressure to melt the toner particles to the page. If the fuser is not operational, then the toner will not be permanently bonded to the paper.

Output file

Virtual virtual printer digitally prints to a file on the storage system.

AFP

Apple Filing Protocol transfers files between mac OS Is used for copying, deleting and other file services.

Drum not cleaning properly

A ghost image is printed on the same page as the original drum in a laser printer will rotate many times to print a single page. If the cleaning process isn't working properly, then a "ghost" image of the previous page contents may appear on the final output.

DHCP

Dynamic host configuration protocol primary protocol commonly used to automate the configuration of IP addresses, subnet masks, and other networking options. DHCP uses both udp/67 and udp/68

RJ45

Ethernet network connection is the standard connector for Ethernet networking over copper cabling.
