Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

Question

a. What is the compression ratio? (uncompressed size/compressed size, expressed as
a ratio)
b. What is the space savings? (1 – compressed/original)

Expert Solution

Compression Ratio

1 MB= 1000KB

Uncompressed size= 1.2 MB= 1200 KB

Compressed Size= 46 KB

Compression ratio= uncompressed size / compressed size

So, compression ratio =1200:46

=600:23
