According to the OSI reference model, the protocol layers are divided into seven layers. Each layer has a specific function 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. Each layer is responsible for a specific aspect of data communication and helps in the smooth transmission of data across a network.

WAN stands for Wide Area Network, which is a type of computer network that spans a large geographical area, such as multiple buildings, cities, or even countries. It is used to connect multiple local area networks (LANs) together, allowing users to share resources and communicate over long distances. Unlike LANs, which are typically confined to a single location, WANs utilize public or private telecommunications infrastructure to transmit data between different locations. Therefore, "Wide Area Network" is the correct answer as it accurately represents the meaning and purpose of WAN.

The correct answer is 1000km. This is because the question is asking about the range of the WAN distance used in continental areas. A WAN (Wide Area Network) is a network that covers a large geographical area, such as a continent. The options provided include distances in meters, centimeters, and kilometers. Since the question specifies "area benua" which means continental area, the most appropriate option would be 1000km, as it represents a longer distance compared to the other options.

FDDI (Fiber Distributed Data Interface) is a networking technology that uses fiber optic cables to transmit data. It operates on two concentric rings, which allow for redundancy and fault tolerance. The correct answer, 100 Mbps, refers to the maximum data transfer rate of FDDI. This means that FDDI can transmit data at a speed of up to 100 megabits per second, making it suitable for high-bandwidth applications and networks that require fast and reliable communication.

The OSI Presentation layer is responsible for ensuring that the data sent by the application layer of one system is understood by the application layer of another system, regardless of the different data formats used by each application. It achieves this by converting the data into a standard format that can be easily interpreted by the receiving application layer. Therefore, the statement that the OSI Presentation layer functions to standardize formats is true.

The statement is false because the correct term for the occurrence of data collision in a computer network is "Collision", not "Broken".

Backing up and restoring data is important in network maintenance in order to document and preserve important data and information. This ensures that important data is not lost in case of any errors or changes in the network. It also allows for the creation of a secure location for storing data.

The correct answer is DTE. DTE stands for Data Terminal Equipment, which refers to the devices or equipment used by customers to connect to a Wide Area Network (WAN) provided by a company. This can include devices such as modems, routers, or switches that enable communication between the customer's network and the WAN.

Mesh topology is a network configuration where multiple devices are interconnected in a network, allowing for multiple routes to be established. This means that if one route fails, there are alternative paths available for data transmission. In a mesh topology, each device is connected to every other device, creating a redundant and fault-tolerant network. This makes mesh topology suitable for routing a large amount of data as it provides high reliability and flexibility.

The correct answer is Data-Link because HDLC (High-Level Data Link Control) is a protocol that operates at the data link layer of the OSI model. This layer is responsible for the reliable transfer of data between nodes on a network, ensuring error detection and correction, as well as flow control. HDLC is commonly used in wide area networks (WANs) for point-to-point and multipoint connections. It provides a synchronous, bit-oriented data link layer protocol that defines how data is framed and transmitted over a physical medium.

The correct answer is "Network." The Network layer in the OSI model is responsible for routing. It determines the best path for data packets to travel from the source to the destination across different networks. It also handles logical addressing and subnetting. The Network layer ensures that data is delivered efficiently and reliably by selecting the appropriate route and managing congestion control.

The correct answer is Hub. A hub is a networking device that connects multiple devices in a network. It operates in half-duplex mode because it only has one collision domain for all its ports. In a half-duplex mode, data can only flow in one direction at a time, and collisions can occur when multiple devices try to transmit data simultaneously. Therefore, a hub is limited to half-duplex mode to avoid collisions and ensure proper communication between devices.

The correct answer is "Hemat kabel". The other options mention the advantages of a star network topology, such as being flexible, easy installation/change of stations, centralized control, and ease of detecting and isolating network management failures. However, "Hemat kabel" (cable saving) is not a recognized advantage of a star network topology.

The correct answer is "Panjang Gelombang". Panjang gelombang refers to the distance between two consecutive points in a wave that are in phase with each other. It represents the physical length of one complete cycle of the wave. It is a fundamental property of a wave and is measured in units of length, such as meters or nanometers.

A log sheet is a record or document where a network administrator can document and track any issues, configuration changes, and troubleshooting activities. It allows the administrator to have a chronological record of events and actions taken, which can be useful for future reference, identifying patterns, and analyzing the network's performance. A diary administrator, history cache, history note, and cache do not accurately describe the purpose of recording network activities.

The given factors are all possible causes of damage to a WAN network, except for incompatible WAN components. Incompatible WAN components would not directly cause damage to the network, but they may lead to connectivity issues or poor performance. The other factors mentioned, such as malfunctioning wireless components, voltage instability, and software issues, can all contribute to network damage or disruption.

The correct answer includes "Point to Point", "Paket Switching", and "Sirkuit Switching". These are all forms of wide area network (WAN) communication. "Point to Point" refers to a direct connection between two devices, "Paket Switching" is a method of transmitting data in packets over a network, and "Sirkuit Switching" is a technique that establishes a dedicated communication path between two devices. These three options are all commonly used in WAN communication.

The factors that can cause damage to a WAN include unstable electrical voltage, sabotage, software malfunctions, malfunctioning network components, and natural disasters. Unstable electrical voltage can lead to power surges or outages, which can disrupt the functioning of network equipment. Sabotage refers to intentional acts of damaging or interfering with the network infrastructure. Software malfunctions can cause errors or crashes in the network, affecting its performance. Malfunctioning network components such as routers or switches can result in connectivity issues or data loss. Natural disasters like earthquakes, floods, or storms can physically damage the network infrastructure, leading to disruptions in communication.

The benefits of a star topology include the ease of detecting network problems for users, as each device is connected directly to a central hub. Additionally, the level of data security is relatively high because if one device is compromised, it does not affect the entire network. The star topology is also flexible, as devices can be easily added or removed without disrupting the entire network.

The correct answer is: "Pertukaran file dapat dilakukan dengan mudah, Komunikasi antar kantor dapat menggunakan chat atau e-mail, Pooling data dan updating data antar kantor dapat dilakukan setiap hari pada waktu yang ditentukan."

The advantages of a WAN (Wide Area Network) include the ease of file exchange, which allows for efficient sharing of files between different locations. Additionally, communication between offices can be facilitated through chat or email, enabling seamless collaboration. Moreover, pooling and updating data between offices can be done regularly at specified times, ensuring that information is consistently up to date across the network. These benefits contribute to improved efficiency, productivity, and data management within an organization.
