The document provides an overview of using CCIS computer systems under different operating systems like Windows NT, Linux, and Unix. It discusses connecting to these systems using PPP or a local area network. It also covers using file managers and editors, sending files remotely, checking email, writing programs, and using the X Window system graphical interface. The guide aims to help users operate effectively under various operating systems.
What Linux can learn from Solaris performance and vice-versaBrendan Gregg
油
The document discusses performance differences between Linux and Solaris (SmartOS). It begins by providing an example of a Perl program that runs 14% slower on one system versus the other. This example is used to explore potential reasons for performance differences between operating systems. The document then categorizes differences into major ("big") differences, such as kernel features, and minor ("small") differences, such as tunable parameters. Several major performance-related features of both Linux and Solaris are highlighted. The document cautions against a "Not Invented Here" viewpoint and suggests areas where each system could potentially learn from the other to improve performance.

This document discusses number representation and coding of information. It covers topics like binary, decimal, and other number systems. It explains how numbers are represented using bits and bytes in binary format. It also describes the maximum number that can be represented using a certain number of bits, like 16-bit, 24-bit and 32-bit representations corresponding to ranges from 0 to 65,535, 0 to 16,777,215 and 0 to 4,294,967,295 respectively. The document also discusses the concept of overflow that can occur during calculations if the result exceeds the maximum representable number.
This document discusses number representation and coding of information. It covers binary, octal, and decimal number systems. It explains how positive and negative numbers are represented using signed value, 1's complement, and 2's complement methods. It discusses the maximum numbers that can be represented using a certain number of bits. Calculations in the different representation methods are also demonstrated.
