Network Protocols and IP Addresses

Flashcards covering key concepts related to network protocols and IP addresses.

What is a protocol?

A protocol is a set of rules that governs communication between devices on a network.

What is the role of protocols in a network?

The role of protocols in a network is to ensure that devices can communicate with each other effectively and efficiently by providing a common language for communication.

What are some common network protocols?

Some common network protocols include HTTP, HTTPS, FTP, FTPS, SMTP, and POP3.

What is HTTP?

HTTP (Hypertext Transfer Protocol) governs communication between a web server and a client.

What is HTTPS?

HTTPS (Hypertext Transfer Protocol Secure) includes secure encryption to allow transactions to be made over the internet securely.

What is FTP?

FTP (File Transfer Protocol) governs file transfers between devices on a network.

What is FTPS?

FTPS (File Transfer Protocol Secure) includes secure encryption to allow file transfers to be made over the internet securely.

What is SMTP?

SMTP (Simple Mail Transfer Protocol) governs email communication between devices on a network.

What is POP3?

POP3 (Post Office Protocol version 3) allows email clients to retrieve email messages from an email server.

What is an IP address?

An IP address is a numerical label that identifies a device on a network.

What is the format of an IP address?

The format of an IP address is four numbers separated by periods, such as 192.168.123.132.

How many bits are in an IP address?

An IP address is a 32-bit number.

What is a network ID?

A network ID is a part of the IP address starting from the left that identifies the specific network on which the device is located.

What is a host ID?

A host ID is a part of the IP address starting from the left that identifies the specific device on the network.

How are IP addresses associated with devices on a network?

IP addresses are associated with devices on a network through a process called DHCP (Dynamic Host Configuration Protocol).

What is a public IP address?

A public IP address is an IP address that can be accessed over the internet.

What is a private IP address?

A private IP address is an IP address that is used in a private network.

What is the difference between a public IP address and a private IP address?

The main difference is that a public IP address can be seen by other devices on the internet, while a private IP address cannot.

What are some implications for security when using public IP addresses?

Public IP addresses are more vulnerable to attacks than private IP addresses because they can be accessed over the internet.

What are some implications for security when using private IP addresses?

Private IP addresses are generally more secure than public IP addresses because they are not visible on the internet.
