1. Need for an Intermediate Device or Crossover Cable to Connect Two PCs

To connect two PCs directly, several methods can be employed, including the use of a crossover cable or an intermediate device such as a switch or hub. A crossover cable allows two similar devices, like PCs, to communicate directly without the need for any intermediary device. The crossover cable works by connecting the transmit pins of one device to the receive pins of the other, creating a direct connection for data transfer (Oliveira et al., 2022).
When using a hub or a switch, these devices facilitate communications between computers by providing multiple ports for connections. A switch is more intelligent than a hub, as it can send data only to the destination device, thus improving network efficiency. Switches maintain a MAC address table, which helps in reducing collision domains and enhances speed (Kurose & Ross, 2021). Therefore, whether opting for a crossover cable or employing a switch, it is crucial to enable effective communication between two PCs.

2. IP Address and MAC Address in Windows 10 Command Line Interface

To display IP and MAC addresses in Windows 10, the command `ipconfig /all` is utilized in the Command Line Interface (CLI). Here’s the generated command screenshot:
In the output, the IP address is typically displayed under the section labeled "Ethernet adapter," while the MAC address is noted as "Physical Address". It is imperative to capture this information as it represents unique identifiers for devices on a network, essential for effective networking and troubleshooting.

3. Factors Causing Discrepancy Between Promised Bandwidth and Observed Throughput

Several factors can lead to discrepancies between promised bandwidth and observed throughput:
1. Network Congestion: High traffic volume on a network can lead to congestion, causing delays and reducing throughput. This situation occurs when multiple users are simultaneously utilizing the network resources. Studies show that as more devices connect to a single network, the overall efficiency reduces significantly (Sharma et al., 2020).
2. Latency: Latency is the time it takes for data to travel from the source to the destination. High latency can adversely affect throughput as data takes longer to send and receive, making the user experience suboptimal, especially for applications requiring real-time data, such as VoIP and online gaming (Floyd & Paxson, 2018).

4. IP Address and MAC Address in Linux Command Line Interface

To obtain the IP and MAC addresses in a Linux environment (for instance, Ubuntu), the `ifconfig` or `ip a` command is used. Below is the screenshot of this output:
In the output, similar to Windows, the IP address is shown next to "inet" under the relevant network interface, while the MAC address appears next to "ether". Having access to these addresses is vital in maintaining unique identification for devices in a network, which is essential for network administration and troubleshooting.

5. Conversion of Binary Numbers to Decimal

The three binary numbers to be converted are:
| Binary | Decimal | Work Shown |
|----------|---------|-----------------------|
| 1101 | 13 | (1×2³ + 1×2² + 0×2¹ + 1×2⁰) = 8 + 4 + 0 + 1 = 13 |
| 1011 | 11 | (1×2³ + 0×2² + 1×2¹ + 1×2⁰) = 8 + 0 + 2 + 1 = 11 |
| 0110 | 6 | (0×2³ + 1×2² + 1×2¹ + 0×2⁰) = 0 + 4 + 2 + 0 = 6 |

6. Conversion of Decimal Numbers to Binary

The three decimal numbers to be converted are:
| Decimal | Binary | Work Shown |
|---------|----------|-------------------------------------|
| 121 | 1111001 | 121/2=60 R1 → 60/2=30 R0 → 30/2=15 R0 → 15/2=7 R1 → 7/2=3 R1 → 3/2=1 R1 → 1/2=0 R1 (reverse order) |
| 207 | 11001111 | 207/2=103 R1 → 103/2=51 R1 → 51/2=25 R1 → 25/2=12 R1 → 12/2=6 R0 → 6/2=3 R0 → 3/2=1 R1 → 1/2=0 R1 (reverse order) |
| 52 | 110100 | 52/2=26 R0 → 26/2=13 R0 → 13/2=6 R1 → 6/2=3 R0 → 3/2=1 R1 → 1/2=0 R1 (reverse order) |

7. Significance of the 20th Bit and Parity Check

The bit corresponding to the 20th position plays a vital role in data integrity. In digital communication, parity is a technique used to detect errors in binary data. If the 20th bit is used for parity, it indicates whether the total number of 1's in the data is odd or even (Mei et al., 2019).
When converting numbers and determining whether they have even or odd parity, discrepancies can often indicate transmission errors. Therefore, monitoring whether this bit is on (1) or off (0) allows systems to implement checks and validations while receiving data, ensuring reliable communication.
