ROM (Read-Only Memory) is a type of storage that contains pre-programmed data that cannot be modified. It can be found in the form of an integrated circuit, which is a small electronic device that contains multiple electronic components such as transistors, resistors, and capacitors integrated onto a single chip. This allows for a compact and efficient way to store data in electronic devices. The other options listed (battery, transformer, air tube, and transistor) are not typically associated with ROM storage.

The given answer states that the biggest problem in a star topology is when there is a break or loose connection in one of the connectors, the entire network will stop functioning. This is because in a star topology, all nodes are connected directly to a central node, and if there is a disruption in the connection between any node and the central node, it will affect the entire network. Therefore, this answer is correct as it accurately describes one of the main drawbacks of a star topology.

The correct answer is Linus Torvald. Linux was initially created by a Finnish student named Linus Torvald.

The correct answer is 256 host. In a class C network, the first 3 octets are used for network identification, leaving only 1 octet for host identification. In this octet, the first address is reserved for network identification and the last address is reserved for broadcast, leaving 256 possible host addresses.

The correct answer is SC and ST. SC and ST are types of connectors commonly used with fiber optic cables. BNC and RJ45 are connectors used with coaxial and Ethernet cables respectively, while RJ11 is used with telephone cables. Therefore, the correct answer is SC and ST.

The correct answer is "Server sedang down". This is because the user is able to ping the loopback address (127.0.0.1) successfully, indicating that the network stack on their computer is working properly. However, they are unable to ping the server (192.168.254.10), which suggests that the server is not responding. Additionally, since the user is able to ping the default gateway successfully, it indicates that their network connection is functioning properly. Therefore, the most likely issue is that the server is currently down.

The given answer states that the characteristic of a bus topology that is not true is that every node only has a cable directly connected to the central node. In a bus topology, every node is connected to a single cable, and there is no central node. Each node is connected to the main cable, and if there is a break or loose connection in one connector, the entire network will be affected. Therefore, the statement that each node only has a cable directly connected to the central node is incorrect.

Kemacetan lalu lintas jaringan disebabkan oleh jumlah pengiriman data yang melebihi kapasitas biasa. Istilah yang digunakan untuk menggambarkan kondisi ini adalah "kongesti".

The speed of a processor is influenced by the internal bus speed, external bus speed, and the presence of a cache memory.
