S-38.113 BASICS OF COMPUTER DATA COMMUNICATIONS,
A LIST OF READING
Yleistä - general
Opetuksessa sovelletaan lähinnä konstruktivistisia
menetelmiä. Käytännössä tämä
näkyy siinä, ettei tietoa pyritä syöttämään
lusikalla opskelijan suuhun - kenties jopa valmiiksi pureskeltuna.
Luento-opetus pyrkii pikemminkin herättämään
ristiriitoja ja nostamaan oppijan mielessä kysymyksiä,
joihin hän saa itse etsiä vastauksia.
Luennoilla käydään vain varsin rajallisesti
läpi asioita, jotka on esitetty kirjassa. Amerikkalaisessa
kirjassa ei käsitellä esimerkiksi eurooppalaisia standardeja
tai telepalveluja Suomessa, joten tämäntyyppiset alueet
täytyy kattaa muilla menetelmillä.
Teletekniikka ei ole - monen nörttipojan harmiksi
- pelkkää tekniikkaa, vaan siihen liittyy subjektiivisia
arvoja. Näitä ei ainakaan kirja välitä lukijalleen.
Kolmas merkittävä näkökohta on,
että samaista kirjaa käytetään eräillä
muillakin opintojaksoilla. Runsaanpuoleisesta sivumäärästä
täytyy jättää jotain muillekin;-)
Näitä ongelmia poistaakseni olen laatinut
oheen listan keskeisistä kirjan sivuista kommentoiden joitain
vain englanniksi.
I have decided to support constructive induction
in teaching this course. Thus during the lectures we will not
concentrate on things clearly described in the book. An American
book will, however, handle neither European standardization nor
telecommunication services in Finland. Also all subjective point
of views have been avoided.
To help the students to orient within the largely
amount of book pages I have collected a list of essential reading
to the following list.
Fred Halsal: Data Communications, Computer Networks
and Open Systems, fourth edition.
Chapter 1
pp. 1 to 22
- Essential, especially standards.
Chapter 2
- 23 to 95
- Cursory read pages 33 to 44. This subject may
be concerned at Hanna's exercises and thus it may be a
potential question in the test.
- Modulation is very essential.
- Interface is very essential and will be concerned
in the nearest tests. You need NOT know the signals, but you MUST
understand what they do. Fig. 2.32 helps!
- X. 21 (p. 88) is not important, why?.
Chapter 3
- 96 to 167
- Contains many interesting things. Read the chapter
through.
- Learn the different code systems and problems
caused by them. Reflect this to standardization.
- Make you familiar with asynchronous transmission
so that you can compare it with synchronous - and it's protocols.
Bit or character oriented synchronous transmission will not be
concerned in the December test.
- Error correction (from p.125) is essential. Reflect
things you read with current modems!
- Data compression (from p. 137) is important.
Try to find out problems involved in it.
- Multiplexing may be important to someone. Read
through to understand the principles.
Chapter 4
- 168 to 216
- Have a 'light' read-through, learn well flow
control (starting from page 198).
Chapter 5
- 217 to 267
- Take no pains, these pages will be read in another
course. Some first pages may, however, be now worth reading.
Chapter 6
- 271 to 351
- We have another course 'Lähiverkot' where
we borrowed Markus to give a lecture to you. Consult him for current
pages or total hits or at least for hints. Refer the 'opetusmonisteet'.
Chapter 7
pp. 352 to 421
Chapter 8
- 423 to 482
- Learn the basic concepts (PDN, PSPDN and CSPDN
for example) and their applications in the real world as well
as brand names used. A visit to the Telegalleria (Oct. 24th
at 16:30) helps, maybe. You need not to learns all those confusing
figures presented in this capture. At HUT we have another course
for them.
Chapter 9
- 483 to 556
- For internetworking we really have another course.
But: we assume that you as an daily Internet user are familiar
with Internet. Something may be asked in the test
Chapter 10
pp. 558 to 637
- Broadband services are state-of-the-art technology.
They do not, however, belong the subjects on a basic course. In
spite of these words you must know the concepts concerned before
the page 571.
Chapter 11
- 641 to 693
- Be familiar with TCP/IP you use daily. Reflect
it to OSI.
- This is a chapter for you desiring the grade
5.
Chapter 12
- 694 to 753
- Contains an interesting short story concerning
data encryption. You can forget all other.
Chapter 13
- 755 to 810
- The chapter contains descriptions of some familiar
concepts. Be ready to explain clearly in the test what for example
TELNET, FTP, SMTP and SNMP are. A short answer will not be accepted
Chapter 14
- 811 to 865
Appendix
- Part D is useful as well as list of acronyms
printed on the back of the book covers. Be sure I ask something
about them
