Exploring Internet and Programming Concepts

What is the primary purpose of Internet Protocols?

• To secure data from unauthorized access

• To enhance the visual design of websites

• To manage user accounts and permissions

• The primary purpose of Internet Protocols is to enable communication and data exchange between devices on a network.

Name one feature of high-level programming languages.

• Machine code compatibility

• Low-level syntax

• Direct access to memory addresses

• Abstraction from hardware details

What device is used to connect multiple networks?

• Switch

• Hub

• Router

• Modem

What is the function of a router in a network?

• The function of a router in a network is to direct data packets between different networks.

• To store data packets for later use.

• To provide a physical connection between devices.

• To amplify the signal strength in a network.

Explain the difference between TCP and UDP.

• TCP and UDP are both connection-oriented protocols with the same speed.

• TCP is reliable and connection-oriented, while UDP is faster and connectionless.

• UDP guarantees delivery of packets, while TCP does not.

• TCP is faster and connectionless, while UDP is reliable and connection-oriented.

What is a database management system (DBMS)?

• A DBMS is a cloud service for hosting websites.

• A DBMS is software that manages databases, allowing users to create, manipulate, and administer data.

• A DBMS is a programming language for data analysis.

• A DBMS is a type of hardware used for data storage.

List two advantages of using high-level languages over low-level languages.

• Simpler syntax for complex algorithms.

• More control over hardware resources.

• 1. Easier to read and write code. 2. Faster development with built-in functions and libraries.

• Better performance in execution speed.

What is the role of a switch in networking?

• A switch connects devices across different networks and routes data based on IP addresses.

• The role of a switch in networking is to connect devices within a LAN and forward data based on MAC addresses.

• A switch acts as a firewall to protect the network from external threats.

• A switch is used to amplify signals over long distances in a WAN.

Define what an IP address is.

• An IP address is a software application used for browsing the internet.

• An IP address is a type of computer virus that spreads through networks.

• An IP address is a physical location of a server in a data center.

• An IP address is a unique numerical label assigned to each device on a network that uses the Internet Protocol for communication.

What is the purpose of DNS in the Internet?

• To provide security for online transactions.

• To manage user accounts on websites.

• The purpose of DNS is to translate domain names into IP addresses.

• To store website content on servers.
