3. Clients and Servers
The client-server paradigm uses the direction of initiation to categorize whether a program is a
client or server. In general, an application that initiates peer-to-peer communication is called a
client. End users usually invoke client programs when they use network services.
By comparison, a server is any program that waits for incoming requests from a client program.
The server receives a request from a client, performs the necessary action sand returns the
result to the client.
4. Ethernet
The term Ethernet generally refers to a standard published in 1982 by Digital Equipment Corp.,
Intel Corp. and Xerox Corp. Ethernet is the most popular physical layer Local Area Network (LAN)
technology in use today.
5. Firmware
Firmware is an embedded software program or set of instructions programmed on a device that
provides the necessary instructions for how the device communicated with other computer
hardware, and is located or stored in a semi-permanent storage area, e.g., ROM, EEPROM, or
Flash memory. Firmware can often be updated by downloading a file from the manufacturer’s
web site or FTP.
6. ICMP (Internet Control Message Protocol)
ICMP provides a method of communicating between the Internet Protocol software on one
machine and the corresponding software on another. It allows a gateway to send error or control
messages to other gateways, or allows a host to diagnose problems with the network
communication.
7. Internet
Physically, the Internet is a collection of packet switching networks interconnected by gateways
that together with the TCP/IP protocol, allows them to perform logically as a single, large and
virtual network. The Internet recognizes hosts using 32-bit IP address.
