Jaringan yang dapat mencakup sebuah negara disebut ... .
- A.
LAN
- B.
MAN
- C.
WAN
- D.
Internet
Correct Answer
C. WANExplanation
A WAN (Wide Area Network) is a network that covers a large geographical area, such as a country. It connects multiple smaller networks, such as LANs (Local Area Networks) and MANs (Metropolitan Area Networks), allowing for communication and data exchange over long distances. Therefore, a WAN is the correct answer as it refers to a network that can cover an entire country.Rate this question:

Perangkat berikut yang berfungsi untuk menghubungkan dua LAN adalah ... .
- A.
Router
- B.
Bridge
- C.
Hub
- D.
Kabel UTP
Correct Answer
B. BridgeExplanation
A bridge is a device that connects two LANs (Local Area Networks) together, allowing them to communicate with each other. Unlike a hub, which simply broadcasts data to all connected devices, a bridge intelligently filters and forwards data only to the intended destination. This helps to improve network performance and reduce unnecessary network traffic. A router, on the other hand, connects multiple networks together, including LANs and WANs (Wide Area Networks), and is responsible for directing data packets between them. A cable UTP (Unshielded Twisted Pair) is a type of network cable used to connect devices within a LAN, but it does not directly connect two LANs together.Rate this question:

Iaringan yang menggunakan Internet Protocol namun hanya dapat diakses oleh kalangan terbatas adalah ... .
- A.
VPN
- B.
LAN
- C.
Internet
- D.
Intranet
Correct Answer
D. IntranetExplanation
An intranet is a private network that uses Internet Protocol (IP) technology but is only accessible to a limited group of people, such as employees within an organization. It is designed to provide internal communication and collaboration tools, as well as access to company resources and information. Unlike the internet, which is a public network accessible to anyone, an intranet is restricted and requires authentication to access its services. Therefore, an intranet is the correct answer as it fits the description of a network that uses IP but is accessible only to a limited group of users.Rate this question:

Perangkat yang berfungsi untuk melindungi jaringan dari serangan luar adalah ... .
- A.
Bridge
- B.
Firewall
- C.
Hub
- D.
Router
Correct Answer
B. FirewallExplanation
A firewall is a device that is designed to protect a network from external attacks. It acts as a barrier between the internal network and the external network, monitoring and controlling incoming and outgoing network traffic. It examines the data packets and filters them based on predetermined security rules. By doing so, it prevents unauthorized access and blocks malicious traffic from entering the network. A firewall is an essential component of network security, ensuring the confidentiality, integrity, and availability of the network resources.Rate this question:
