What is an Operating System?
UNIX is a modern day operating system. But, what is an operating system?
One definition of an operating system is:
"the programs of a digital computer system which, together with the
characteristics of the computer system, form the basis of the various
operational modes of the digital computer system and especially those
which control and supervise the processing of programs."
This compact and comprehensive description assumes the understanding of
some concepts. The "digital computer system" is the hardware. These are the
physical components of the computer which can be touched. Thirty years ago
this description would have been sufficient. Today addicitonal concepts are
required. Besides the "body", a computer system must have a "soul". Since
a "soul" must be immaterial, it can only consist of software in a computer.
This software is the operating system.
Therefore, the characteristics, better yet the hardware characteristics of
the computer system, together with the operating system form the basis of the
processing capabilities. The operating system does not include all the
software in a computer. This is the software which permites the user of the
system to execute the applications software specifically written to be used
with that operating system. The user of a modern computer system is no
longer confronted by the hardware, but with the operating system such as UNIX.
From this viewpoint of the user, there are three basic operating modes
o Batch Processing
o Conversational (or interactive) mode
o Real-time processing
Batch processing originated during the time when executable programs were
read on a card reader in the form of a punched card dec, consisting of
control statements and the actual program.. The punched cards have now
disappeared - at best they can still be found as scraps for notes - but the
concept and the operating mode remains.
Batch jobs
A barch job must be defined completely and in the proper sequence. The ]
control statements are usually stored in a file. One of these statements calls
the program to be executed Several programs can be initiiated within a batch
job. However, all required operating devices such as disck storage, magnetic
tape storage, printer, plotter, etc. must be requested from inside the job.
No calls to the operating system are permitted since they are not answered.
Unix and MS-DOS,CP/M or OS/2
UNIX is the oldest of the three systems, even though it has been discussed
only in the last few yeards. CP/M and MS-DOS are oriented strongly toweds
the main features if UNIX. The newer versions of MS-DOS resemble UNIX
very much. Even the command syntax is very similar The largest step in
the direction of UNIX came with DOS Version 2.0.
Viewed from the users perspectivem the file systems of UNIX and DOS resemble
earch other alot. Both orginate in a root are structured hierarchically
(like a tree). Directories permit the user to retain an overview. Besides
the common files and directories, UNIX also knows an additional type, the
device file. Devide files provide an interface to the physical devices
which are addressed just like an ordinart file. Special systems call for
control of the peripherals and are therefore not required.
Internally a UNIX file differs from a CO/M or DOS file. The orientation
towards the record oand bloack structure of a disk has been dropped. UNIX
recoqnizes only blocks which contain byte chains. The type of file does
not make any difference to UNIX, since it is only a concern of the
application program using the file.
+---------------------+
| II. History of Unix |
+---------------------+
The history of UNIX begain in 1969 at Bell Labortatories, which is part
of AT&T. Kennth Thompson developed an operating system writtern in
DEC PDP-7 assembler code for the "Soace Travel" project. He called it
UNIX. The names was derived from the preceding operating system
Multics which was less conservative in the use of scare computer
resources. UNIX was at first a single user variant of Multics.
In 1971 UNIS was implemented again in assembler code on ther more powerful
computers of the PDP-11 series. To become more independant from another
change in hardware, Thompson planned a new implementation in a higher level
language. He developed the B language from BCPL in 1970, but this language
did not prove powerful enough.
After Dennis Ritchie, also a Bell, created the C language, UNIX was
rewritten almost completely in this higher level language by 1073. By
utilizing the advantages of C, UNIX became capable of handling multiusers
and multi-tasking. UNIX was then machine independent and the start signal
for its rapid distribution was given. At that time, Version 5 was still
being distributed to American universites free of chare for use in research
and education. Berkeley University in particular developed UNIX further.
The real triumph begain in 1975 with Version 6. AT&T granted source
licenses to intrested companies, but without support. From this
release, derivatives of UNIX were created with spilt away from the main
development.
Version 7 of UNIX appeard about the same time as the first 16-bit
microprocessors. This is the version onwhich most of todays Unix
derivatives are based. A third branch also developed, which is
characterizedmost by the Microsoft product XENIX.
Since 1983 AT&T has tried to bring the various development streams
together again. Training, documentation and other support is
being offered. The external sign is a new number series know as System
V.

Well this is the end of Unix Hacking Volume I. You should have a firm
awareness with UNIX now and I hope you continue to grow and wait for
our UNIX Hacking Voulume II which will contains holes into the unix
