Study Notes
Memory Addressing
- 32-bit: Utilizes up to 4 GB of address space on Windows operating systems.
- 64-bit: Capable of addressing more than 4 GB of space; varying versions can address between 8 to 192 GB.
Wireless Standards
- 802.11a: Operates on the 5 GHz band for wireless networking.
- 802.11b: Functions on the 2.4 GHz band with speeds up to 10 Mbps.
- 802.11g: Uses the 2.4 GHz band; supports speeds of up to 54 Mbps, and is backward-compatible with 802.11b.
- 802.11n: Offers speeds up to 600 Mbps; compatible with 802.11a, b, and g.
Display Technologies
- 8-bit high color: VGA mode that can represent approximately 16 million colors but only displays 256 simultaneously.
- Active matrix display: LCD technology leveraging thin-film transistors (TFT), allowing rapid changes in display due to dedicated transistors at each pixel.
Power and Connectivity
- AC adapter: Converts AC power to required voltages for devices, commonly used for portable PCs.
- Accelerated graphics port: Local bus designed solely for video, enabling direct communication between processor and video card.
- Adapter card: Expansion card installed on the motherboard to enhance functionality (e.g., video adapters, network interface cards).
Networking
- Access control: Involves managing user access to computer and network resources through authentication and authorization.
- Access control entry: Single record in an access control list (ACL) detailing permissions for one user or group.
- Access control list: A NTFS file system component containing multiple access control entries for files and folders.
- Ad hoc mode: Wi-Fi networking mode allowing peer-to-peer communications without central wireless access points.
System Components
- Accessory bay: Laptop compartment for single media devices that can be swapped with others.
- Active partition: Primary partition designated for system use during startup; Windows can only boot from this partition.
Network Protocols
- Address Resolution Protocol (ARP): Resolves an IP address to a MAC address.
- Advanced Communications Riser (ACR): Riser card standard for accelerated audio and modem functions using one PCI slot, for networking support.
Communication Skills
- Active communication: Involves behaviors like active listening and speaking to promote engagement in conversation.
- Active listening: Skills and attitudes essential for effectively listening to others.
- Active speaking: Responses made during conversations that reflect engagement and understanding.
Miscellaneous
- Activation: A process employed by software companies to prevent piracy.
- ACT (Activity Light): NIC status indicator showing data transmission activity.
- Address bus: Collection of wires marking addresses in memory; wider buses can address more memory (e.g., 32-bit bus for 4 GB, 36-bit for 64 GB).
