wiring is needed.
RJ-45 - The standard connector for Ethernet cables with the same shape as a phone plug, but
they contain more wires and are a little larger.
Router - Adevice often used to connect multiple computers to the Internet. The computers are
shielded from the Internet as many routers have security features like a firewall.
Security - Acomputer connected to the Internet is vulnerable to attacks from other people who
might be trying to steal data or use your computer to attack other computers. Arouter provides
protection from many kinds of attacks.
Static IP Address - The opposite of using DHCPto get your IP address. With a static IP
address, the same IP address is always assigned to a single computer. With DHCP, the IP
address is assigned from a bank of available addresses and may not be the same every time
the computer is switched on.
Streaming - Sending data over a network which is then used as soon as it is received. An
Internet radio station uses streaming audio that is played back as soon as it is received.
Subnet - This is part of the advanced network setup. This allows a group of computers on a net-
work to be separated form other groups.
Subnet mask - The mask that indicates what IPAddresses belong to the subnet.
TCP (Transmission Control Protocol) - Avery common protocol used in combination with the
IP protocol, often called TCP/IP. TCPis used for reliable data transfer of files, etc. when data
must be received error-free. The protocol uses an acknowledgment system through which the
receiver must send a reply for each packet sent. The companion protocol to TCP is UDP, which
provides faster, but less accurate, transmission.
UDP (User Datagram Protocol) - This is a protocol often used when speed is more important
than error-free data. A good example is audio or video where a small amount of errors are
preferable to audio or video not playing back at the correct speed. The protocol gets its speed
advantage by sending packets without waiting for an acknowledgment from the recipient.
USB (Universal Serial Bus) - A high speed bus for connecting devices to a PC. USB version
1.0 and 1.1 can reach up to 12 Mbps while the newer USB v2.0 can reach up to 400 Mbps. A
USB device can be connected or disconnected without switching the PC off; this is unlike older
devices that need the computer to be restarted.
WWW (World Wide Web) - Originally, the Internet was a text- only world. The introduction of the
World Wide Web brought about the Web browser and a graphical way of surfing the Internet.
winipcfg - This is the Windows 98/ME equivalent of ipconfig and is used to find out the comput-
er's IPAddress and host name.
