Mac addresses(media access control)
MAC addresses are 48- or 64-bit identifiers linked to the hardware of network adapters. They are expressed as hexadecimal strings like 01-23-45-67-89-AB. There are two types: universally administered addresses, which are assigned at manufacture with the first three octets identifying the manufacturer, and locally administered addresses, which can be manually changed but must be unique on the local subnet. MAC addresses can be useful for security and troubleshooting network issues.
Network Sockets
Overview of socket API.
A network socket is an interface for an application to connect to a host‘s network stack (part of the OS). Sockets provide an abstraction of the network. Applications use the transport services available on the socket interface for communication with a peer application.
Transport protocol such as TCP, UDP or SCTP offer different levels of service. TCP for example provides reliable stream-oriented transport service while UDP more reflects the best-effort kind of service provided by the underlying IP protocol layer.
Sockets are bound to a transport address. For TCP/IP sockets this means an IP address and port number.
Sockets provide only very basic data transport services without any higher level functions like parameter marshaling or serialization. These functions have to be performed by the applications. These functions are often hidden in middleware platforms like distributed object technologies (CORBA, RMI, DCOM) or web service frameworks (WCF, JAX-WS).
Multicast sockets make the IP multicast capability accessible to applications. Multicast sockets are often used for streaming services where multiple applications are recipients of the same data packets.

Dhcp ppt
DHCP is a protocol that dynamically assigns IP addresses and other network configuration parameters to devices on a network. It uses a client-server model where DHCP clients make requests to DHCP servers which maintain pools of addresses. A DHCP client will broadcast requests at initialization and use a 4-step process to get an address assigned. It will later enter renewal states to extend its lease before initialization again if needed. This allows for efficient dynamic allocation and management of IP addresses on a network.

The document outlines the history and development of ARPANET and the Internet from 1957 to 2001. It describes key events like the launch of ARPA in 1958, the beginning of the ARPANET project in 1966, and the first connections between nodes in 1969. It also notes the creation of email in 1971, the connection of 23 nodes by 1971, and the shutdown of ARPANET in 1989. The number of websites grew from 50 in 1992 to 30 million in 2001.
Presentation about Fiber Optics
Optical fiber is a flexible transparent fiber made of high quality glass or plastic that transmits light between two ends. It functions as a waveguide or light pipe. Optical fibers are widely used for fiber optic communications due to their ability to transmit signals over longer distances and higher bandwidths compared to other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are safe from electromagnetic interference. Optical fibers have been used for communication since the 1840s and are now used for transmitting data at rates as high as 400 gigabits per second. Optical fiber provides benefits such as greater bandwidth, immunity to electrical interference, and lower signal attenuation over long distances compared to conventional copper cables.

ARPANET was the world's first operational packet switching network and predecessor to the global Internet. Hard bounces occur when emails are permanently undeliverable, while soft bounces happen when emails reach the recipient's server but bounce before delivery. Computer spam refers to junk emails or newsgroup posts, some containing viruses. The Internet connects millions of global computers, while an intranet is a private network within an organization only accessible to members. POP retrieves email from servers, phishing involves scam emails pretending to be legitimate, and encryption involves encoding data while decryption decodes encrypted data. Netiquette refers to proper online behavior which affects one's reputation, and routers forward data packets between networks.
