Study Notes

Types of Memory

Synchronous Dynamic RAM (SDRAM): Operates in sync with the memory bus for improved performance.
Double Data Rate Synchronous Dynamic RAM (DDR SDRAM): Transfers data at double the rate of standard SDRAM, allowing two reads and writes per CPU clock cycle.
DDR2 SDRAM: Similar to DDR but operates at higher clock speeds, maintaining the double transfer rate.
DDR3 SDRAM: Doubles the memory bandwidth of DDR2 by increasing the clock rate.
DDR4 SDRAM: Quadruples the maximum storage capacity of DDR3, enhancing performance.
Graphics Double Data Rate (GDDR): Specialized RAM for graphics processing, associated with dedicated GPUs and includes versions like GDDR2 through GDDR5.

Multi Channel System Memory

Enhances data transfer rates by utilizing multiple communication channels between DRAM and the memory controller.

Error Correction Code (ECC) RAM

Found in workstations and servers for critical data, ECC RAM detects and corrects memory errors, reducing crashes and improving reliability.

Central Processing Unit (CPU)

The CPU executes commands and processes instructions from other hardware and software components, outputting information to monitors and performing tasks.

CPU Architectures and Features

Comprises of:
- Arithmetic Logic Unit (ALU): Executes arithmetic and logic operations.
- Processor Registers: Supply operands and store results from the ALU.
- Control Unit: Directs the operation of the processor.

Printer Speed, Quality, and Color

Speed: Measured in pages per minute (ppm).
Quality: Assessed in dots per inch (dpi).
Color: Uses the CMYK model (Cyan, Magenta, Yellow, and Black) for inkjets.

Reliability and Total Cost of Ownership

Factors include warranty, scheduled servicing, Mean Time Between Failures (MTBF), and Total Cost of Ownership (TCO).

Automatic Document Feeder (ADF)

Allows automatic feeding of documents into printers, often providing collation.

Network Scanning

Multifunction Devices (MFDs) can scan and send documents to various locations such as cloud storage, network folders, or email attachments.

Laser Printer Characteristics

Advantages: Low per-page cost, high capacity, fast printing, and high-quality output.
Disadvantages: High initial cost and expensive toner cartridges.

Laser Printer Parts

Imaging Drum, Transfer Roller, Pickup Rollers, Toner Cartridge, Fuser Assembly, Duplexing Assembly.

Laser Printing Process

Involves seven steps: Processing, Charging, Exposing, Developing, Transferring, Fusing, and Outputting.

Wireless Printer Connections

Bluetooth: Allows pairing for printing from mobile devices.
Wi-Fi: Supports 802.11 standards for direct connections.

Purpose of Print Servers

Facilitate client access to print resources, manage print jobs, and provide feedback about device status.

Software vs. Hardware Print Servers

Software print servers share printers using applications, while hardware print servers manage connections independently, improving performance and reliability.

Printer Security

Critical measures include disabling unsecured network access, using firewalls, regularly updating firmware, and changing default passwords.

Printer Maintenance Guidelines

Laser Printers: Use HEPA filters during cleaning, watch for low toner alerts.
Inkjet Printers: Use the correct ink type, avoid refilling cartridges, and ensure that cartridges are not empty.
Thermal Printers: Replace paper regularly and clean heating elements.
Impact Printers: Replace ribbons and check print head quality.
3D Printers: Regular cleaning, replacing components, and updating firmware.

Common Scanner Issues and Solutions

Won't Turn On: Check the power cord connections.
Strange Noises: Normal calibration sounds upon startup.
Won't Scan: Rebooting the computer can resolve software issues.

Scanner Troubleshooting

Problems with buttons and scanning quality can often be corrected by restarting or adjusting settings such as resolution.

Printer Selection Criteria

Factors include intended use, cost of consumables, print speed, and quality of output.
