Computer Network Pdf Computer Network Network Topology What is an operating system? what are the primary functions of an operating system? 0x001af38 rc general idea of usage is to ”orchestrate” services to develop application. why do we need distributed control algorithms? an algorithm is sometimes called protocol if it specifies coordination more than computation. What is an operating system? “the one program running at all times on the computer” is the kernel. everything else is either a system program (ships with the operating system) or an application program. a process is a program in execution. it is a unit of work within the system. program is a passive entity, process is an active entity. 1.1 what is an operating system? 3 1.1.1 the operating system as an extended machine 4 1.1.2 the operating system as a resource manager 5 1.2 history of operating systems 6 1.2.1 the first generation (1945–55): vacuum tubes 7 1.2.2the second generation (1955–65): transistors and batch systems8 1.2.3 the third generation (1965–1980): ics. This chapter starts by considering the reasons for attaching a computer to a network, and underlines them by comparing and contrasting the capabilities of a stand alone computer and a networked computer.

Introduction network operating systems extend the facilities and services provided by computer operating systems to support a set of computers, connected by a network. the environment managed by a network operating system consists of an interconnected group of machines that are loosely connected. The primary purpose of the network operating system is to allow shared file and printer access among multiple computers in a network, typically a local area network (lan), a private network or to other networks. Networks and operating systems (252 0062 00) chapter 1: introduction to operating systems if operating systems were airways (~year 2000) unix airways everyone brings one piece of the plane along when they come to the airport. Chapter 1 provides a brief survey of the processor, memory, and input output (i o) elements of a computer system. the topic of operating system (os) design covers a huge territory, and it is easy to get lost in the details and lose the context of a discussion of a particular issue.
