Which of the following statements about the ISO/OSI reference model are correct?

This is a reference model only. I.e. it regulates the tasks of the protocol layers, but not how they are to be implemented.

The top three layers are for transport, the remaining layers are for applications.

The layers of the ISO/OSI reference model are numbered from bottom to top.

The model is independent of the hardware used or the network topology.

Which statements about the layer model and communication protocols are correct?

Application logs are found in the ISO/OSI layer model on the lowest layer.

The ISO/OSI layer model contradicts the concepts of a layer architecture.

Communication protocols are, among other things, agreements on the establishment, monitoring and termination of connections.

A layer model isolates the technical details of the layers from each other.

What is the name of the language with which the web pages can be described?

«Hypertext Markup Language» or «HTML»

"Transmission Control Protocol/Internet Protocol" or short "TCP/IP"

"Media-Access-Control" or short "MAC"

"Transport Layer Security" or short "TLS"

Which statements about "line switching" are correct?

All Internet protocols are optimized for line switching.

Intermediate exchanges store data packets and forward them on the optimal line.

Line switching has a worse performance of the entire network than packet switching.

The participants have their own channel during the transmission.

Responsible for addressing and forwarding data packets..

Which statements about Transport Layer Security (TLS) are correct?

Encryption is completely sufficient for establishing a secure connection in e-banking.

Formerly known as Secure Sockets Layer (SSL)

A certificate is only required in rare cases for TLS, then when a lot of money is involved.

Allows encrypted and secure communication over the Internet.

Which statements about operating systems are correct?

Multi-user system requires at least two concurrent users.

Operating systems for desktop and mobile devices do not differ in their core functionalities.

The hardware can only be used in interactive dialog mode.

An operating system includes all programs required for starting up a computer.

Which statements on normalization are correct?

In the standard normalization procedure, data sets are gradually converted from the 1st normal form to the 3rd normal form.

The number of tables tends to decrease with increasing normalization.
