Embedded Unit4&5

Which file system is best suited for systems requiring frequent read-only access with limited storage?

• EXT4

• RAMDisk

• CRAMFS

• JFFS

CRAMFS is primarily used for

• High-speed volatile storage

• Compressed read-only storage

• Journaling flash file systems

• Network file storage

JFFS stands for

• Java Flash File System

• Journaling Flash File System

• Joint File Format System

• Journaled Fast File Storage

Wear-leveling in JFFS2 helps in

• Improving RAM speed

• Reducing network latency

• Increasing CPU performance

• Preventing premature flash memory wear-out

PROC file system provides

• Physical file storage

• Kernel and process information

• Networked file access

• Permanent data storage

Kernel space optimization is typically aimed at reducing

• Memory footprint of kernel

• Network bandwidth

• Power consumption

• Application data size

Application space optimization in embedded Linux mainly targets

• Reducing kernel size

• Increasing CPU speed

• Enhancing network latency

• Reducing memory used by applications

The best practice to optimize embedded Linux application storage is to

• Store all data on RAMDisk

• Utilize CRAMFS for frequently modified data

• Remove unused libraries and binaries

• Always mount file systems remotely via NFS

Why might embedded Linux systems prefer compressed file systems like CRAMFS?

• Faster CPU performance

• Enhanced RAM utilization

• Reduced storage requirements

• Improved network access

Which activity is NOT typically part of embedded file system optimization?

• Kernel parameter tuning

• Application trimming

• Using compressed filesystems

• Adding extensive documentation in memory
