Which conceptual model divides network communication into seven distinct layers, from Physical to Application?
Correct answer: B
The OSI Model divides network communication functions into seven standardized layers.
In the OSI Model, which layer is responsible for the physical transmission of raw bits over a medium?
Correct answer: B
The Physical Layer handles the transmission of raw, unstructured bit streams over a physical medium.
In the OSI Model, which layer is responsible for node-to-node data transfer and error detection on the physical link?
Correct answer: A
The Data Link Layer manages reliable node-to-node transfer and detects errors from the physical layer.
In the OSI Model, which layer handles logical addressing and routing of data between different networks?
Correct answer: C
The Network Layer manages logical addressing (like IP) and routes data across networks.
In the OSI Model, which layer ensures complete data transfer and manages error recovery and flow control end-to-end?
Correct answer: B
The Transport Layer ensures reliable, end-to-end data delivery with error recovery and flow control.
In the OSI Model, which layer manages and controls the connections (sessions) between applications?
Correct answer: D
The Session Layer establishes, manages, and terminates connections (sessions) between applications.
In the OSI Model, which layer translates, encrypts, or compresses data for the Application layer, such as formatting or converting character sets?
Correct answer: B
The Presentation Layer handles data translation, encryption, and compression for the application layer.
In the OSI Model, which layer is closest to the end user, providing network services directly to applications like browsers and email clients?
Correct answer: D
The Application Layer provides network services directly usable by end-user applications.
Which simpler four-layer networking model, underlying the modern internet, is commonly contrasted with the seven-layer OSI Model?
Correct answer: B
The TCP/IP Model is a simpler four-layer framework that underlies how the modern internet actually operates.
Which protocol is used to transfer web pages between a browser and a web server?
Correct answer: C
HTTP is the protocol used to transfer web page data between browsers and servers.
Which protocol is the secure, encrypted version of HTTP, indicated by a padlock icon in browsers?
Correct answer: C
HTTPS encrypts the data exchanged between browser and server, unlike plain HTTP.
Which protocol is used to transfer files between computers over a network?
Correct answer: B
FTP is specifically designed for transferring files between computers over a network.
Which protocol translates human-readable domain names, like www.example.com, into numerical IP addresses?
Correct answer: B
DNS translates domain names into the numerical IP addresses computers use to locate each other.
Which protocol automatically assigns IP addresses to devices joining a network?
Correct answer: C
DHCP automatically assigns IP addresses and other network settings to devices on a network.
Which protocol allows a user to remotely log into and control another computer over a network, typically insecurely?
Correct answer: C
Telnet allows remote login to another computer but transmits data, including passwords, without encryption.
Which protocol allows secure, encrypted remote login and command execution on another computer over a network?
Correct answer: D
SSH provides encrypted remote access to another computer, unlike the insecure Telnet.
Which suite of communication protocols forms the foundational language of the internet, governing how data is transmitted?
Correct answer: B
TCP/IP (Transmission Control Protocol/Internet Protocol) is the foundational protocol suite of the internet.
Which protocol within TCP/IP breaks data into packets, ensures reliable delivery, and reassembles them in order at the destination?
Correct answer: C
TCP ensures reliable, ordered delivery of data packets between devices.
Which protocol within TCP/IP sends data faster than TCP but without guaranteeing delivery or order, often used for streaming?
Correct answer: B
UDP prioritizes speed over reliability, commonly used for streaming and gaming where some data loss is acceptable.
Which term describes a virtual, numbered 'channel' (like 80 for HTTP) used to direct network traffic to specific services on a device?
Correct answer: C
Port numbers direct incoming network traffic to the correct service or application on a device.
Which port number is conventionally used for standard, unencrypted HTTP web traffic?
Correct answer: D
Port 80 is the standard port for unencrypted HTTP traffic.
Which port number is conventionally used for secure, encrypted HTTPS web traffic?
Correct answer: B
Port 443 is the standard port for encrypted HTTPS traffic.
Which port number is conventionally used for File Transfer Protocol (FTP) connections?
Correct answer: C
Port 21 is the standard control port used by FTP.
Which port number is conventionally used for sending email via SMTP?
Correct answer: B
Port 25 is the traditional standard port used for SMTP email transmission.
