28. Unix Operating System

29. Unix Operating System
UNIX was one of the first operating systems to be written, in 1971.
Advantages of UNIX are…
Multitasking – multiple programs can run at one time.
Multi-user – allows more than a single user to work at any given time. This is accomplished by sharing processing time between each user.
Safe – prevents one program from accessing memory or storage space allocated to another program, and enables file protection, requiring users to have permission to perform certain functions, such as accessing a directory, file, or disk drive.

30. UNIX History
The UNIX operating system was born in the late 1960s. It originally began as a one man project led by Ken Thompson of Bell Labs, and has since grown to become the most widely used operating system.
In the time since UNIX was first developed, it has gone through many different generations and even mutations.

31. General Characteristics of UNIX as an Operating System (OS)
Multi-user & Multi-tasking - most versions of UNIX are capable of allowing multiple users to log onto the system, and have each run multiple tasks.
Over 30 Years Old - UNIX is over 30 years old and it's popularity and use is still high. Over these years, many variations have spawned off and many have died off, but most modern UNIX systems can be traced back to the original versions.

32. General Characteristics of UNIX as an Operating System (OS)
Free Applications and Even a Free Operating System - of all of the applications available under UNIX, many of them are free. The compilers and interpreters that we use in most of the programming courses here at UMBC can be downloaded free of charge. Most of the development that we do in programming courses is done under the Linux OS.
Less Resource Intensive - in general, most UNIX installations tend to be much less demanding on system resources. In many cases, the old family computer that can barely run Windows is more than sufficient to run the latest version of Linux.
Internet Development - Much of the backbone of the Internet is run by UNIX servers. Many of the more general web servers run UNIX with the Apache web server - another free application.

33. Unix Operating System

34. Parts of unix There are three types of unix. The kernel The shell
The Programme

35. Parts of the UNIX OS
The Kernel - handles memory management, input and output requests, and program scheduling. Technically speaking, the kernel is the OS. It provides the basic software connection to the hardware. The kernel is very complex and deals with the inner workings of these things, and is beyond the scope of this course. The kernel is covered in detail in “Operating Systems.”

36. Parts of the UNIX OS
The Shell and Graphical User Interfaces (GUIs) - basic UNIX shells provides a “command line” interface which allows the user to type in commands. These commands are translated by the shell into something the kernel can comprehend, and then executed by the kernel.

37. Parts of the UNIX OS
The Built-in System Utilities - are programs that allow a user to perform tasks which involve complex actions. Utilities provide user interface functions that are basic to an operating system, but which are too complex to be built into the shell. Examples of utilities are programs that let us see the contents of a directory, move & copy files, remove files, etc...

38. Parts of Unix

39. UNIX Interfaces
There are really 2 means of connecting to UNIX computers here at UMBC:
You can be sitting in front of a dual-bootable PC that you have booted into Linux and logged onto. All of your commands are then being run locally on that computer. When you logon in this manner you have a full GUI environment.
You can connect remotely to one of the UNIX servers (whether from home or at the labs). This is often how your projects are suggested to be developed as they are graded on those same servers. When you logon in this manner you have a command line (or text based) environment. You can also open up a command line on local lab machines as well.

40. Macintosh Operating System

41. Mac oS
