1) data lost when power off
2) high cost
3)high transfer speed

secondary storage:

What are the different performance measures and to represent a computer systems performance
Weegy: Multi-core processors can offer significant performance improvements over their single-core counterparts for certain kinds of parallelized tasks, often demanding new programming paradigms to efficiently utilize the complex architecture involved. [ Multi-core processors also present unique challenges for the performance analyst because the architecture of these processors has significant impacts on the way work is scheduled, memory is allocated, and instructions are executed. ] (More)

Discuss the operating system’s performance measurements
Weegy: Which operating system are you referring to? User: UNIX Weegy: A fundamental simplifying assumption of Unix was its focus on newline-delimited ASCII text for nearly all file formats. [ There were no "binary" editors in the original version of Unix – the entire system was configured using textual shell command scripts. The common denominator in the I/O system was the byte – unlike "record-based" file systems. The focus on text for representing nearly everything made Unix pipes especially useful, and encouraged the development of simple, general tools that could be easily combined to perform more complicated ad hoc tasks. The focus on text and bytes made the system far more scalable and portable than other systems. Over time, text-based applications have also proven popular in application areas, such as printing languages (PostScript, ODF), and at the application layer of the Internet protocols, e.g., FTP, SMTP, HTTP, SOAP, and SIP. ] (More)
