    Berikut ini yang merupakan contoh jaringan LAN, kecuali jaringan komputer ... .

    • Dalam laboratorium

    • Dalam satu perusahaan

    • Antar cabang suatu bank

    • Dalam satu lembaga/kantor

    Correct Answer
    A. Antar cabang suatu bank
    Explanation
    The correct answer is "antar cabang suatu bank". This is because a LAN (Local Area Network) refers to a network that is confined to a small geographical area, such as a single building or campus. While all the other options mentioned (dalam laboratorium, dalam satu perusahaan, dalam satu lembaga/kantor) can be examples of LANs, connecting branches of a bank is an example of a WAN (Wide Area Network) rather than a LAN.

    • Linear

    • Server

    • Tree

    • Client

    Correct Answer
    A. Client
    Explanation
    The correct answer is "client". In computer networking, the term "client" refers to a device or software application that requests services or resources from a server. In this context, the "client" is the entity that initiates communication with the server and makes requests for data or services.

    • Email spoofing

    • Pharming

    • Spoofing

    • Browser hijackers

    Correct Answer
    A. Spoofing
    Explanation
    Spoofing is the correct answer because it refers to the technique of deceiving or tricking someone by falsifying information, such as IP addresses, in order to gain unauthorized access or manipulate data. In this case, the question specifically mentions the act of falsifying IP addresses, which aligns with the concept of spoofing. Email spoofing, pharming, and browser hijackers are related but not specifically focused on the manipulation of IP addresses.

    Correct Answer
    A. RJ 45
    Explanation
    The correct answer is RJ 45. RJ 45 is the connector used for UTP (Unshielded Twisted Pair) cables, which are commonly used for Ethernet networks. RJ 45 connectors have eight pins and are designed to connect to the RJ 45 ports on devices such as computers, routers, and switches. These connectors provide a secure and reliable connection for transmitting data over the network.

    • Transport layer

    • Internet layer

    • Network interface layer

    Correct Answer
    A. Network interface layer
    Explanation
    The correct answer is Network interface layer. The network interface layer is responsible for sending and receiving data to and from the physical network media. It provides the interface between the network protocol stack and the physical network. This layer handles tasks such as framing the data into packets, addressing, error detection and correction, and media access control.

    Iaringan yang menggunakan Internet Protocol namun hanya dapat diakses oleh kalangan terbatas adalah ... .

    • VPN

    • LAN

    • Internet

    • Intranet

    Correct Answer
    A. Intranet
    Explanation
    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:

  • 21. 

    Perangkat berikut yang berfungsi untuk menghubungkan dua LAN adalah ... .

    • Router

    • Bridge

    • Hub

    • Kabel UTP

    Correct Answer
    A. Bridge
    Explanation
    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:

  • 22. 

    Pada topologi jaringan komputer semua sentral dihubungkan secara langsung pada medium transmisi, jaringan ini disebut ... .

    • Ring

    • Bus

    • Star

    • Client Server

    Correct Answer
    A. Bus
    Explanation
    In a bus network topology, all the nodes are connected directly to a common transmission medium, such as a single cable. Each node can communicate with all other nodes by broadcasting the message onto the medium. This type of network is called a bus network.

    Rate this question:

  • 23. 

    Tindakan melakukan intercepsi secara real-time yang tidak diotorisasi terhadap komunikasi pribadi disebut ... .

    • Eavesdropping

    • Spoofing

    • Pharming

    • Spyware

    Correct Answer
    A. Eavesdropping
    Explanation
    Eavesdropping refers to the unauthorized act of intercepting and listening to private communications in real-time. It involves secretly accessing and monitoring conversations or messages without the knowledge or consent of the parties involved. This can be done through various means such as wiretapping, hacking into communication channels, or using specialized equipment to capture and decode signals. Eavesdropping is considered a violation of privacy and can be illegal in many jurisdictions.

    Data hasil enkripsi disebut ... .

    • Plain teks

    • Sandi Teks

    • Cipher teks

    • Enkrip Teks

    Correct Answer
    A. Cipher teks
    Explanation
    The correct answer is "Cipher teks" because when data is encrypted, it is transformed into a form that is not easily understood or readable. This transformed data is called cipher text.

    Rate this question:

  • 25. 

    Perbedaan sistem jaringan LAN dan WAN adalah ... .

    • Letak pemasangan komputer

    • Area pemasangan komputer

    • Sistem jaringan komputer

    • Koneksi ke Internet

    Correct Answer
    A. Koneksi ke Internet
    Explanation
    The correct answer is "Koneksi ke Internet". The difference between LAN (Local Area Network) and WAN (Wide Area Network) lies in their connection to the Internet. LAN refers to a network that is confined to a small geographical area, such as a home, office, or building, and does not necessarily require an Internet connection. On the other hand, WAN refers to a network that covers a larger geographical area, such as multiple buildings, cities, or even countries, and requires an Internet connection to connect different LANs or other networks together.
