Explanation
The correct answer is "Peer to peer". In a peer-to-peer network, each computer in the network can act as both a client and a server, allowing for decentralized communication and resource sharing. This means that the network can continue to function even if one server fails, as the other computers can still communicate and share resources with each other.

Explanation
The correct answer is RAM. RAM stands for Random Access Memory and it is a type of computer memory that is used to store data that is currently being used by the computer. It is a temporary storage space that allows the computer to quickly access and manipulate data. Unlike a hard disk, which is a permanent storage device, RAM is volatile and its contents are lost when the computer is turned off. Therefore, RAM is the peripheral that is used to store data temporarily.

Explanation
The given IP address 192.168.1.0/26 has a subnet mask of 26 bits, which means that there are 6 bits available for host addresses. In binary, these 6 bits can represent 2^6 = 64 different combinations. However, the first and last combinations are reserved for network and broadcast addresses respectively, leaving 62 combinations for usable host addresses. Therefore, the correct answer is 62.

Explanation
Firewall is a network security system that acts as a barrier between a trusted internal network and an untrusted external network. It functions to forward data packets to their intended destination (client or server) while also blocking unwanted packets. It is a type of security that helps protect the network from unauthorized access and potential threats.

Explanation
Disk defragmenter is a tool used to organize and optimize files on a hard disk. It rearranges fragmented data on the disk, making it easier and faster for the computer to access and retrieve files. This tool helps to improve overall system performance by reducing the time it takes to read and write files. It is different from other options mentioned, such as scan virus, system information, and task manager, which have different purposes and functions.

Explanation
NIC stands for Network Interface Card. It is a hardware component used to connect a computer to a network. It enables the computer to send and receive data over the network. Unlike the other options mentioned (VGA Card, Super I/O, Empeg Card), which are not specifically designed for network connectivity, NIC is specifically designed for this purpose. Therefore, NIC is the correct answer for the card used to connect a network.

Explanation
The Presentation layer of the OSI model is responsible for the formatting and presentation of data to the application layer. It acts as an interface between the user and the computer, ensuring that the data is in a format that the application layer can understand. This layer is responsible for tasks such as data encryption, compression, and decompression. Therefore, the correct answer is Presentation.

Explanation
The subnet mask 255.255.255.248 is a /29 subnet, which means it has 29 bits for the network portion and 3 bits for the host portion. In this case, the host portion can accommodate 2^3 - 2 = 6 valid hosts. The -2 is because the first address in the subnet is reserved for the network address, and the last address is reserved for the broadcast address. Therefore, there are 6 valid hosts in this subnet.

Explanation
A repeater is a device that amplifies and retransmits a signal to extend its reach or improve its quality. In the context of data transmission, a repeater is used to strengthen the signal and ensure that it reaches its intended destination without degradation. Unlike a hub, switch, or router, which are used for different purposes in networking, a repeater specifically focuses on signal amplification and transmission. Therefore, a repeater is the correct answer for this question.

Explanation
The correct answer is "/dev". In Linux, the "/dev" directory is used to represent devices, including hard drives. The other options mentioned in the question, such as "C:\" and "D:\", are specific to Windows operating systems and are not applicable in Linux.
