Which term refers to the type of memory that loses its contents when power isn't present?
A) Asynchronous B) Dynamic C) Nonvolatile
D) Static E) Synchronous F) Volatile
The term that refers to the type of memory that loses its contents when power isn't present is F) Volatile. Memory, in the context of computing, refers to the storage and retrieval of digital information by a computer or other electronic device. Memory can be divided into two broad categories: primary memory and secondary memory.
Primary memory, also known as RAM (Random Access Memory), is a type of volatile memory that is used to temporarily store data and program instructions while the computer is running. RAM is typically made up of small, fast memory chips that can be accessed quickly by the computer's processor. The amount of RAM in a computer determines how many programs can be run simultaneously and how quickly the computer can switch between them.
Secondary memory, also known as storage, refers to non-volatile memory that is used to store data and programs for long-term use. This includes hard disk drives (HDDs), solid-state drives (SSDs), and removable storage devices such as USB flash drives and memory cards. Unlike RAM, which is erased when the computer is turned off, data stored in secondary memory remains intact even when the power is turned off.

What is the maximum number of subnets and hosts per subnet for the 192.168.50.247 255.255.255.224 network?
1) 2 subnets, 126 hosts per subnet
2) 4 subnets, 62 hosts per subnet
3) 8 subnets, 30 hosts per subnet
4) 16 subnets, 14 hosts per subnet
The correct answer is option 3: 8 subnets, 30 hosts per subnet. This means that the network can be divided into 8 subnets, each containing up to 30 hosts.
The maximum number of subnets and hosts per subnet for the 192.168.50.247 255.255.255.224 network can be determined by looking at the subnet mask, which is represented by 255.255.255.224. This subnet mask indicates that the network uses 27 bits for the network portion and 5 bits for the host portion.
To calculate the number of subnets, we need to determine the number of bits that are used for the network portion of the address. In this case, 27 bits are used, which means that there are 2⁵ or 32 possible subnets. However, two of these subnets are reserved for network and broadcast addresses, leaving 30 usable subnets.
To calculate the number of hosts per subnet, we need to determine the number of bits that are used for the host portion of the address. In this case, 5 bits are used, which means that there are 2⁵⁻² or 30 possible hosts per subnet. The -2 is because the first and last addresses in each subnet are reserved for the network and broadcast addresses.
So, the correct option is 3). This information is important for network administrators who need to allocate IP addresses and manage network traffic effectively.

Unlike a traditional IDS, an IPS must sit ____________________ (in the flow of traffic) to be able to interact effectively with the network traffic.
Unlike a traditional IDS, an IPS must sit "in-line" (in the flow of traffic) to be able to interact effectively with the network traffic.Explanation:
Intrusion Prevention Systems (IPS) are designed to detect and block network-based attacks in real-time. Unlike an Intrusion Detection System (IDS), which only passively monitors network traffic and raises alerts when it detects suspicious activity, an IPS is positioned directly in the path of network traffic, allowing it to actively inspect and block malicious traffic in real-time.This "in-line" positioning is crucial for the effectiveness of an IPS because it enables it to intercept and block malicious traffic before it can reach its intended target. This is particularly important in today's fast-paced threat landscape, where attackers are constantly developing new and sophisticated techniques to evade detection and infiltrate networks.By sitting in-line, an IPS is able to inspect every packet of data passing through the network, in real-time, and take immediate action to block any suspicious or malicious traffic. This helps organizations to better protect their network assets and data from potential cyber threats.
