Compression Files

What is the purpose of compressing files?

• To reduce file size and make storage, transfer, and sharing more efficient.

• To slow down file transfer

• To increase file size

• To make sharing less efficient

Name one common file format used for compression.

• ZIP

• RAR

• TAR

• 7z

Explain the difference between lossy and lossless compression.

• Lossy compression permanently eliminates some data to reduce file size, while lossless compression reduces file size without losing any data.

• Lossy compression retains all data while reducing file size

• Lossy compression reduces file size without losing any data

• Lossless compression permanently eliminates some data to reduce file size

How does compression help in saving storage space?

• Compression increases the storage space needed by duplicating data.

• Compression reduces the amount of space needed to store data by encoding it more efficiently.

• Compression has no impact on storage space.

• Compression only works for specific types of files.

What are the potential drawbacks of compressing files?

• Loss of quality, longer processing times, potential for corruption or data loss, need for specific software

• Enhanced quality, reduced storage space, compatibility with all devices

• Increased security, faster processing times, improved file organization

• Decreased risk of corruption, easier file sharing, automatic file recovery

What is the role of a compression algorithm in file compression?

• To increase the size of a file by adding unnecessary data

• To rearrange the file content randomly

• To reduce the size of a file by encoding data efficiently and removing redundancy.

• To encrypt the file for security purposes

List two popular software programs used for file compression.

• WinZip, 7-Zip

• WinRAR

• PeaZip

• StuffIt

Describe the process of decompressing a compressed file.

• Decompressing a file involves encrypting the compressed data further

• The process of decompressing a compressed file involves using a decompression tool or software to reverse the compression process and restore the original file.

• Decompressing a file requires increasing its file size

• Decompressing a file involves converting it to a different file format

What are some advantages of using compressed files?

• Limited storage space, same file transfer speeds, no impact on organization

• Reduced storage space, faster file transfer speeds, improved organization

• Increased storage space, slower file transfer speeds, disorganized files

• Inflated storage space, slower file transfer speeds, worsened organization

How does compression affect the speed of file transfer?

• Compression causes data loss, leading to slower transfer speeds.

• Compression has no impact on file transfer speed.

• Compression increases the size of the file, slowing down the transfer speed.

• Compression reduces the size of the file, making it quicker to transfer over a network or between storage devices.
