Lesson 11
IT Infrastructure II
LO
1. You know the concept of distributed computing and are able to explain it,
you know the client-server model and the different assignments between
clients and servers, and the multi-tier architecture concept.
2. You know the current status of 5G mobile phone technology in Switzerland,
you can explain the advantages and disadvantages of 5G compared to
previous generations of mobile communications, you know the factors that
influence the spread of 5G and what the Massive Internet of Things
(MIoT) is and what role 5G plays in this area.
3. You know the difference between the World Wide Web (WWW) and the
Internet and can explain it in your own words.
4. You know the structure of a Uniform Resource Locator (URL) and why
URLs are used in communication on the Internet.
5. You know what the DNS system does when a DNS server is used in
communication, which task an IP address takes on, and when it is needed
for communication.
6. You know the purpose of the network protocols and you can name the
most important Internet protocols at the application level and explain how
they work.
7. You can explain what a layer model is and give an example.
8. You can explain the term "cloud computing" and name the characteristics
of cloud computing.
9. You can describe the service models «Infrastructure-as-a-Service»,
«Platform-as-a-Service» and «Software-as-a-Service».
10. You know what Hypertext Markup Language (HTML) is and for what
purpose you need HTML, the structure of a HTML file and can explain it in
your own words and what a browser is and what purpose it serves when
surfing the WWW.
, Lesson 11
1. Distributed Computing
The Principle of Distributed Processing (Single-Tier)
- Different tasks can be divided between different
computers.
- Same principle as with the division of labor (Taylor,
1911).
- The "Client & Server principle" is also a form of
distributed processing.
- Clients request something.
- Servers respond / provide something.
- A client can access different servers in the course of the
application
- A server can serve many clients at the same time.
Dual Role and Distribution to Several Layers (Multi-Tier)
- Often there are dual roles as client and server.
- Work is not only shared between two different computers but across several levels.
