Objectives

1.1 Operating System Basics
1.2 Network Operating System Overview

1.1 Operating System Basics

1.1.1 Overview of PC Operating Systems
Desktop computers gained widespread popularity in the early 1980s.
Desktop computer efficiency was limited by the lack of shared information and resources.
1.1.2 PCs and Computer Networks
Local area networks (LANs) were created to share data and peripheral devices (e.g., printers) amongst multiple PCs.
NOSs required more processing power than typical desktop PCs.
1.1.3 Kernel
The core of the operating system.
Loaded into memory upon boot.
Handles hardware, memory, processes, and various programs.
1.1.4 User Interface (UI)
The user's method of interaction with the OS.
Translates input (keystrokes, mouse clicks) into program actions.
Utilizes graphical elements (windows, menus, icons).
1.1.5 File System
Organizes files and directories on the system.
File Allocation Tables (FAT32): supports up to 2TB partitions.
New Technology File System (NTFS): supports up to 16 Exabytes.
1.1.6 Common Desktop Operating Systems
Microsoft Windows (popular desktop OS).
Mac OS (proprietary, based on a customized version of UNIX).
UNIX/Linux (old, open-source, various versions).

1.2 Network Operating System Overview

1.2.1 Common Network Operating Systems.
1.2.2 Windows vs. Linux NOS Comparison
1.2.3 Client-Server Model
Most network applications are client-server based.
A server provides services to client programs.
The server receives requests from clients and returns appropriate information.
1.2.4 Evaluating Customer Resources and Requirements
Assess customer needs and existing resources for appropriate system selection.
Evaluate hardware needs (e.g., large disks, high performance) for servers.
Resources such as existing hardware, budget, and expertise are important factors in system procurement.
Linux can often reuse existing hardware while maximizing system performance.
