Jaringan yang dapat mencakup sebuah negara disebut dengan . . . .
Correct Answer
C. C. WAN
Explanation
A WAN (Wide Area Network) is a network that can cover a large geographical area, such as a country. It connects multiple LANs (Local Area Networks) across different locations and allows for communication and data transfer between them. Therefore, the correct answer is c. WAN.
2.
Berikut ini merupakan manfaat dari jaringan computer, kecuali . . . .
Correct Answer
D. D. Kita dapat mengakses data orang lain tanpa diketahui
Explanation
The given correct answer is d. Kita dapat mengakses data orang lain tanpa diketahui. This statement is incorrect because accessing someone else's data without their knowledge or permission is considered unethical and a violation of privacy. In a computer network, the focus is on sharing resources, using data collaboratively, and improving reliability, not on unauthorized access to others' data.
3.
Perangkat berikut yang berfungsi untuk menghubungkan dua LAN adalah . . . .
Correct Answer
B. B. Bridge
Explanation
A bridge is a device that connects two LANs together. It operates at the data link layer of the OSI model and uses MAC addresses to forward data between the two LANs. Unlike a router, which operates at the network layer and uses IP addresses, a bridge does not perform any routing or network address translation. Instead, it simply forwards data packets based on their MAC addresses. This allows devices on one LAN to communicate with devices on the other LAN as if they were all connected to the same network.

Perangkat berikut yang berfungsi untuk mengisolasi arus data yang datang dari satu LAN dengan yang datang dari LAN yang lain adalah . . . .
Correct Answer
A. A. Router
Explanation
A router is a device that is used to connect multiple networks together and route data between them. It is designed to separate and isolate data traffic coming from one LAN (Local Area Network) from another LAN. Routers have the ability to analyze the destination IP address of incoming data packets and determine the most efficient path for them to reach their destination. This allows them to direct data traffic between different LANs and prevent them from interfering with each other. Therefore, a router is the correct device for isolating data traffic coming from different LANs.
5.
Perangkat berikut yang memungkinkan dua buah komputer saling berkomunikasi dan mempertukarkan data dalam jaringan adalah . . . .
Correct Answer
D. D. LAN Card
Explanation
A LAN card, also known as a network interface card (NIC), is a device that allows two computers to communicate and exchange data in a network. It is a hardware component that is installed in each computer and provides a physical connection to the network. The LAN card enables the computer to send and receive data packets over the network, allowing for communication and data transfer between the two computers.
6.
Protokol jaringan yang berfungsi mengirimkan dan menerima data ke dan dari media fisik jaringan adalah . . .
Correct Answer
D. D. Network Interface Layer
Explanation
The correct answer is d. Network Interface Layer. The Network Interface Layer is responsible for sending and receiving data to and from the physical network media. It handles tasks such as framing the data into packets, adding physical addresses, and error detection and correction. It also manages the physical connection to the network, including the network interface card and the cables.
7.
Bentuk penyusupan yang dilakukan dengan cara memalsukan identitas username dikenal dengan istilah . . . .
Correct Answer
A. A. Spoofing
Explanation
Spoofing is a form of intrusion where the attacker falsifies their identity or impersonates someone else's identity in order to gain unauthorized access to a system or network. This can involve creating fake usernames or manipulating existing ones to deceive the system into granting access. Spoofing can also be used to manipulate network traffic or deceive users into revealing sensitive information.
8.
Program yang berfungsi untuk memonitor jaringan dan menangkap paket data yang melewati jaringan disebut . . . .
Correct Answer
C. C. Sniffer
Explanation
A program that monitors a network and captures data packets passing through the network is called a sniffer. Sniffers are commonly used for network troubleshooting and security analysis purposes. They can capture and analyze network traffic, allowing administrators to identify and resolve network issues, as well as detect and investigate any suspicious or unauthorized activities on the network.
9.
Teknik pengamanan data yang dilakukan dengan cara menyandikan data-data yang dikirim dikenal dengan istilah . . . .
Correct Answer
C. C. Secure Socket Layer
Explanation
The correct answer is Secure Socket Layer. Secure Socket Layer (SSL) is a security protocol that encrypts data transmitted over the internet. It ensures that the data being sent between a web server and a browser remains private and secure. SSL uses encryption algorithms to scramble the data, making it unreadable to anyone who might intercept it. This helps to protect sensitive information such as credit card numbers, login credentials, and personal data from being accessed by unauthorized individuals.
10.
Teknik pengamanan data yang dilakukan dengan cara memfilter arus komunikasi yang masuk dan keluar dikenal dengan istilah . . . .
Correct Answer
A. A. Firewall
Explanation
A firewall is a security measure that filters incoming and outgoing network traffic. It acts as a barrier between a trusted internal network and an untrusted external network, allowing only authorized communication to pass through while blocking unauthorized access. It helps protect against unauthorized access, malicious attacks, and data breaches by monitoring and controlling network traffic based on predetermined security rules. Therefore, a firewall is the correct answer for the given question.
