Study Notes
Selecting a Computing Device
- Consider the type of user you are and your computing needs, such as casual use, power use, or mobility.
Evaluating the CPU Subsystem
- A CPU's processing power is determined by its clock speed, number of cores, and amount of cache memory.
- Multiple-core technology enables the independent execution of multiple sets of instructions simultaneously.
- Cache memory has three levels, defined by proximity to the CPU, with Level 1 being the fastest and Level 3 being the largest.
Evaluating the Memory Subsystem
- The amount of RAM needed depends on the type of user and their computing needs.
Evaluating the Storage Subsystem
- No specific details mentioned in the provided text.
Evaluating the Media Subsystems
- Sound Cards:
- Enable the computer to drive the speaker system.
- Now routinely integrated into the motherboard.
- 3D sound technology provides better omnidirectional sound.
- Video Cards:
- Necessary for complex graphics, high-definition video editing, and graphics-rich gaming.
- Various standards of video memory available, including GDDR3 and GDDR5.
- Newer GDDR5X video memory chips offer faster data rates and improved energy efficiency.
- Minimum of 1 GB of video memory recommended, with 2 GB or more suggested for serious gamers.
- Multiple video cards can be used in one system for improved performance.
- Some video cards can support up to six monitors.
- GPU (Graphics Processing Unit) is a separate processing chip specialized for 3D graphics and image/video processing.
Maintaining System Reliability
- Install a reliable antivirus package.
- Run spyware and adware removal programs.
Understanding and assessing hardware, evaluating your system, and selecting a computing device based on your needs and user type.
