What does ISDN stand for?
- A.
  
  Internet scores display nation
- B.
  
  Intergrated services digital network
- C.
  
  Internet service display network
Correct Answer
B. Intergrated services digital network

Explanation
ISDN stands for Integrated Services Digital Network. It is a telecommunications network that allows the transmission of voice, data, and video over digital lines. It was developed to provide a faster and more reliable connection compared to traditional analog networks. ISDN offers various services such as telephone calls, video conferencing, and data transfer, all through a single digital line.

What are the four types of networks?
- A.
  
  Bus Ring Star Mesh
- B.
  
  Flower Water Rain Main
- C.
  
  Coke Ring Flower Mash
Correct Answer
A. Bus Ring Star Mesh

Explanation
The correct answer is "Bus Ring Star Mesh." These are the four types of network topologies commonly used in computer networking. A bus network consists of a single cable that connects all devices in a linear fashion. In a ring network, each device is connected to two other devices, forming a closed loop. A star network has a central device, such as a switch or hub, which connects all other devices. Lastly, a mesh network has multiple interconnected devices, providing redundant paths for data transmission.

- A.
  
  Essay words
- B.
  
  Losers
- C.
  
  Topolgy
- D.
  
  Interconnecting devices
Correct Answer
D. Interconnecting devices

Explanation
The given answer, "interconnecting devices," accurately explains what routers, modems, and WAPs are. These devices are used to connect different networks or devices together, allowing for communication and data transfer. Routers are responsible for directing network traffic, modems connect devices to the internet, and WAPs enable wireless connectivity. Therefore, they can all be classified as interconnecting devices.

- D.
  
  Wireless access pin
Correct Answer
B. Wireless access point

Explanation
WAP stands for "wireless access point." It is a device that allows wireless communication devices to connect to a wired network. It acts as a bridge between the wireless and wired networks, enabling devices such as smartphones, laptops, and tablets to access the internet or other network resources without the need for physical cables.

What does a network bridge do?
- A.
  
  Connects multiple network segments at the data link layer (layer 2) of the OSI model
- B.
  
  Connects multiple segments to the network
Correct Answer
A. Connects multiple network segments at the data link layer (layer 2) of the OSI model

Explanation
A network bridge is a device or software that connects multiple network segments at the data link layer (layer 2) of the OSI model. It allows for the forwarding of data packets between different segments, effectively extending the network and allowing devices on different segments to communicate with each other. By operating at the data link layer, a network bridge can efficiently manage and control the flow of data between segments, improving network performance and reducing congestion.

  20
- C.

- D.
  
  7
- E.
  
  1
Correct Answer
D. 7

Explanation
The OSI model is a conceptual framework that standardizes the functions of a communication system into seven different layers. Each layer performs specific tasks and interacts with the layers above and below it. These layers include the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer. Therefore, the correct answer is 7.

Which are layers in the OSI model?
- A.
  
  Application layer , presentation layer and physical layer
- B.
  
  Application layer, switch layer , bridge layer
- C.
  
  Presentation layer, hub layer physical layer
Correct Answer
A. Application layer , presentation layer and physical layer

Explanation
The correct answer is application layer, presentation layer, and physical layer. These are the three layers in the OSI model. The application layer is responsible for providing network services to the user, such as email and file transfer. The presentation layer handles data formatting and encryption. The physical layer deals with the actual transmission of data through the physical medium, such as cables or wireless signals.

- A.
  
  1
- B.
  
  6
- C.
  
  9
- D.
  
  4
Correct Answer
B. 6

Explanation
The presentation layer is the sixth layer in the OSI model. It is responsible for the formatting and presentation of data to the application layer. This layer ensures that the data is in a format that the application layer can understand and interpret. It also handles tasks such as encryption and compression of data for secure transmission.

What is the function of a Gateway?
- A.
  
  Is enabling connection to other networks
- B.
  
  The way in which you get out of the internet
- C.
  
  To direct traffic
Correct Answer
A. Is enabling connection to other networks

Explanation
A gateway is a network device that enables connection to other networks. It acts as an entrance or exit point for data to flow between different networks. It facilitates communication and data transfer between networks by converting protocols, managing traffic, and directing data packets to their intended destinations. Without a gateway, devices within a network would not be able to connect or communicate with devices on other networks.
