When a Web client receives an IP address of a Web server, the client browser uses the IP address and port 80 to request Web services. This request is sent to the server using the Hypertext Transfer Protocol (HTTP). The FTP server allows a client to exchange files between devices and manage files remotely, sending management commands to start applications. FTP sessions are sent to the server using destination port 21 (data FTP 20). After opening the session, the server will use port 20 to transfer

Understanding IP Addresses
An IP address is a series of 32 binary bits (ones and zeros). In a byte, the rightmost bit has a value of 1, and the values of the remaining bits from right to left are 2, 4, 8, 16, 32, 64, and 128. The first part identifies the network, and the second part identifies a host on that network. Both parts are necessary in an IP address. For example, the first three octets (192.168.1.8) identify the network portion of the address, and the last octet (57) identifies the host.

Network Management Functional Areas
Network management maximizes efficiency and productivity in a data network transparently to users. It performs various management tasks:
- Fault Management: Locating and correcting network problems and failures, including configuration adjustments.
- Configuration Management: Identifying and configuring critical devices, requiring an inventory to track updates.
- Security Management: Controlling access to information and data.
- Network Performance Management: Measuring the

Lecture 4 – Client/Server and Sockets
Client-Server: Provides high-level functionality that users access. They use the transport mechanism provided by a network (such as the internet). They are identified by high-level names, while low-level details are hidden. They provide functions for exposing, accessing, and using services.
Single Server Multiple Services: Makes better use of CPU cycles and reduces the cost of additional server overhead. When there are multiple services on a single server, they
