Adresace

QuestionAnswer
Pro počítače ve stejném segmentu sítě platí: mají stejné NetID
Maska IP adresy určuje: rozdělení IP adresy na NetID a HostID
Pro počítače z různých segmentů sítě platí: mohou mít stejné HostID
Kam odesílá data počítač, pokud je cílová adresa z jiného segmentu sítě? výchozí brána
Pro počítače se stejným NetID platí: posílají si data přímo
Pro síť, která obsahuje pouze huby a switche (L2) platí: skládá se z jednoho segmentu
Pro výchozí bránu počítače platí: adresa počítače a výchozí brány jsou ve stejném segmentu
Zkrácený zápis masky IP adresy (např.: /24) udává: počet bitů NetID
Pokud HostID obsahuje pouze jedničky (binárně), pak platí: adresa je broadcast
Pokud HostID obsahuje pouze nuly (binárně), pak platí: adresa je adresa sítě
Pokud se síť skládá pouze z jednoho segmentu, pak platí: počítače nemusí mít nastavenu výchozí bránu
Logický součin IP adresy počítače a masky je adresa sítě
Dva počítače z jednoho segmentu sítě nemohou mít: stejné HostID

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
