Pořadatel převezme prodlužovací kabel a předá přístupový kód návštěvníkům.

Because these are perfective verbs. In Czech, the non-past form of a perfective verb usually refers to the future.

• převezme = he/she will take over / receive
• předá = he/she will hand over / pass on

So although the forms look like present tense endings, their meaning is future here.

Compare:

• přebírá = is taking over / takes over regularly (imperfective)
• převezme = will take over once, as a completed action (perfective)

The same pattern applies to:

• předává = is handing over / hands over regularly
• předá = will hand over

Pořadatel means organizer, event organizer, or sometimes steward/attendant, depending on context.

It comes from the idea of someone who organizes or manages something. In this sentence, it is the person responsible for handling things such as equipment and access details.

Grammatically, pořadatel is:

• masculine animate singular
• in the nominative case, because it is the subject of the sentence

So Pořadatel převezme... means The organizer will take over...

Because it is the direct object of převezme, and in this sentence that direct object happens to have the same form as the nominative.

• kabel = cable
• prodlužovací = extension / extending
• prodlužovací kabel = extension cable

Case details:

• kabel is masculine inanimate
• singular accusative of masculine inanimate nouns is usually the same as the nominative
• so kabel stays kabel

The adjective must agree with the noun:

• masculine inanimate
• singular
• accusative

For this type of adjective, that gives prodlužovací.

So:

• nominative: prodlužovací kabel
• accusative: prodlužovací kabel

They look the same here.

This is another noun phrase in the accusative singular, because it is the thing being handed over.

• kód = code
• přístupový = access
• přístupový kód = access code

Again:

• kód is masculine inanimate
• accusative singular = same as nominative singular

So both words stay in the form you see.

It is similar to English access code, where access describes the type of code.

Because návštěvníkům is in the dative plural.

The verb předat often works like to hand something over to someone:

• předat co? = what? → the thing handed over
• předat komu? = to whom? → the receiver

In the sentence:

• přístupový kód = the thing being handed over → accusative
• návštěvníkům = the people receiving it → dative plural

So:

• návštěvník = visitor
• návštěvníkům = to the visitors

The ending -ům is a common dative plural ending for masculine nouns.

Because návštěvníky would be accusative plural, and that would make them the direct object.

But here the visitors are not the thing being handed over. They are the recipients of the access code.

Compare:

• Pořadatel vidí návštěvníky. = The organizer sees the visitors.
  Here návštěvníky is accusative, because the visitors are the direct object.

• Pořadatel předá kód návštěvníkům. = The organizer will hand the code to the visitors.
  Here návštěvníkům is dative, because they receive something.

So Czech marks the role of the noun by case ending.

The prefix changes the meaning.

• vzít / vezme = to take
• převzít / převezme = to take over, receive, assume responsibility for

So převezme prodlužovací kabel does not just mean physically grabbing a cable. It suggests something more like:

• receiving it from someone
• taking charge of it
• accepting it officially or procedurally

Similarly:

• dát = to give
• předat = to hand over, pass on, transfer

So předá přístupový kód sounds more specific and appropriate than just dá kód.

Because Czech has no articles like English a/an/the.

Czech leaves definiteness to context. So the same noun form can mean:

• an organizer
• the organizer

depending on the situation.

In this sentence, context tells you how to translate it naturally into English. If the situation is already known, English will often use the:

• The organizer will take over the extension cable and hand the access code to the visitors.

But Czech itself does not mark that with an article.

Because both verbs have the same subject, so Czech does not need to repeat it.

Structure:

• Pořadatel převezme... a předá...

This means:

• The organizer will take over... and hand over...

English works the same way:

• we normally say The organizer will take over the cable and hand over the code
• not The organizer will take over the cable and the organizer will hand over the code

So the omission is completely normal.

Yes. Czech word order is relatively flexible because case endings show grammatical roles.

The neutral order here is:

• Pořadatel převezme prodlužovací kabel a předá přístupový kód návštěvníkům.

But other orders are possible for emphasis, for example:

• Pořadatel návštěvníkům předá přístupový kód.
• Přístupový kód předá pořadatel návštěvníkům.

These alternatives may sound more marked or emphasize different information.

However, for learners, the original order is a very good neutral pattern:

• subject
• verb
• object
• and then another verb phrase

Not necessarily. The singular noun návštěvník is grammatically masculine, but in the plural it can often refer to a mixed group of people.

So návštěvníkům can mean:

• to male visitors
• to a mixed group of visitors

If you specifically wanted to refer only to female visitors, you would use the feminine noun:

• návštěvnice = female visitor
• návštěvnicím = to the female visitors

But in many real contexts, masculine plural forms can function generically.

A rough guide:

• Pořadatel ≈ po-zhah-da-tel, but with the Czech ř, which is a special sound not found in English
• převezme ≈ przhe-vez-me
• prodlužovací ≈ pro-dloo-zhoh-vah-tsee
• přístupový ≈ przhee-stoo-poh-vee
• návštěvníkům ≈ naaf-shtehv-nyee-koom

About ř:

• it is one of the hardest Czech sounds for English speakers
• it is something like a mix of r and zh (the sound in measure)

You do not need to master it immediately to be understood. Many learners first approximate it with:

• r
• or zh
• or a combination of the two

That is normal in the early stages.

Because the sentence describes two completed, one-time actions in sequence:

1. the organizer will receive/take over the extension cable
2. then the organizer will hand over the access code to the visitors

Perfective verbs are natural when the speaker sees the actions as whole, completed events.

If you used imperfective forms, the meaning would change. It could suggest:

• an ongoing process
• repeated action
• habitual action
• more focus on the activity itself rather than completion

So the perfective choices převezme and předá fit a schedule, instruction, or planned procedure very well.

Yes. a is the normal Czech word for and.

In this sentence it joins two coordinated actions:

• převezme prodlužovací kabel
• předá přístupový kód návštěvníkům

So the whole sentence is literally structured as:

• Organizer will take over extension cable and will hand over access code to visitors.

Very straightforwardly, a connects the two verb phrases just like English and.
