A student sends an email containing text, images, and an attached audio file to a friend in another city. The information successfully reaches the recipient because several communication components work together to transfer the data across the network.

A smartphone user uploads a video to a cloud storage service. Before transmission, the phone converts the information into signals suitable for network transfer. Which communication component is performing this initial task?

A company shares a presentation over a network. The actual presentation file containing slides, images, and text is the information being transferred between devices. In network communication, this transferred information is known as:

An organization uses fiber optic cables to connect computers in different departments. The cables provide the pathway through which signals travel from one device to another. Which network communication component do these cables represent?

Two computers are physically connected with cables, but they cannot exchange information because they use different communication rules. Which missing component is preventing successful communication?

A network engineer observes that a receiving computer converts incoming signals back into their original form before displaying them to the user. Which communication component is responsible for this stage?

A small office network uses a device that forwards every incoming data packet to all connected computers, regardless of the intended destination. This causes unnecessary network traffic during busy hours.

A school upgrades its network by replacing hubs with devices that examine packet addresses and send data only to the intended computer. This significantly reduces network congestion.

A home network is connected to the Internet through a device that determines the best path for data packets traveling between different networks. Which device performs this function?

A company needs to connect a modern computer network with an older mainframe system that uses different communication standards. Which device acts as a translator between the two networks?

A university campus consists of several buildings connected through a high-speed network. Students can access shared printers and files within the campus. Which type of network best describes this setup?

An international company links offices located in different countries through communication lines and satellite connections. Employees can exchange information globally through this network.

A city-wide network connects multiple schools, government offices, and libraries using fiber optic communication lines. The network covers approximately 30 kilometers.

A web browser requests a webpage from a server. The protocol responsible for transferring webpages and related content between the browser and server is:

A user uploads and downloads large files between two computers connected through a network. Which protocol is primarily designed for this purpose?

A company employee sends an email to a client in another country. Which protocol is mainly responsible for sending the email message from the sender's mail server?

When a user types a website address into a browser, the system converts the human-readable name into a numerical IP address before communication begins. Which Internet service performs this task?

A network administrator explains that data traveling through the Internet is divided into smaller units, each of which may follow different routes before reaching the destination and being reassembled.

A company is choosing a topology for a small temporary network. The design should use minimal cabling and be inexpensive, but the company accepts the risk that failure of a single cable could stop the entire network.

A hospital requires a network where individual cable failures should not affect the communication of other computers. The network should also be easy to troubleshoot and expand.

A user sends an email from one computer to another. During transmission, the data is converted into a standard format so that different systems can understand it. Which OSI layer performs this function?

While browsing the internet, data packets travel through several networks. A router determines the best path for these packets to reach their destination. Which OSI layer is responsible for this task?

During a video conference, the connection between two devices is established, maintained, and terminated after the meeting ends. Which OSI layer manages these communication sessions?
