Network Protocols Implementation Steps: FTP, TCP, UDP
FTP Server Implementation Steps
- Start the program.
- Include necessary header files.
- Declare necessary variables.
- Print: “Enter the port address”.
- Create a TCP socket (‘SOCK_STREAM’) and store its file descriptor in ‘sd’.
- Check if the socket creation was successful. If not, print an error message.
- Setup server address structure (Family to IPv4 (‘AF_INET’), IP address to any available address (‘INADDR_ANY’)).
- Convert the port number to network byte order.
- Bind the socket to the server address.

Embryo Formation in Flowering Plants
The formation of embryos in flowering plants begins after fertilization, when the zygote (formed by the fusion of the male and female gametes) undergoes a series of divisions and differentiations. Though the initial stages of development are similar in both dicots and monocots, the final structure of the embryo differs significantly.
Dicot Embryo Formation
In dicot plants (e.g., bean, pea), the zygote first divides asymmetrically into a small terminal cell and a

Carl Jung’s Collective Unconscious (1875-1961)
I: The Unconscious Mind
The unconscious mind encompasses everything not currently in consciousness but accessible to it.
Personal Unconscious
This layer includes forgotten memories and repressed experiences that attract or repel us. Unlike Freud’s view, Jung did not include instincts here.
Collective Unconscious
This is an evolutionary product, a shared, innate knowledge everyone is born with, of which we are unaware. It indirectly influences our experiences

Media Representation of Ethnicity and Gender in Music Videos
Ethnicity in Music Videos
Duran Duran – Rio (1982)
Representation: Ethnicity is largely absent or tokenized. The video features a white British band surrounded by exotic, tropical imagery, filmed in locations like Antigua. Women featured are racially ambiguous or white, and largely passive.
- Key Example: The tropical backdrop is used to enhance the band’s glamour, but the local culture or people are not acknowledged — the setting becomes a backdrop for white luxury.
- Theory Link: Said’s Orientalism
