Old Terms for Technology Old Timers

The older you are the more you probably use these “old terms”. Are you guilty of any of these?

Dial

rotary-phoneMany people still say they are “dialing” a phone number. The term goes back to the beginning of the telephone era, when phones had a rotary dial. Rotary phones have not been used for decades, but people still say they’re dialing away.

Hanging Up

Carbon Copy

This term originally referred to the days before making photo copies was possible. back in the “old” days in order to make copies, you would need to place a sheet of carbon paper behind the original sheet so the ink transferred over.

Clicker

clicker

You probably know someone who always this. Plenty of people refer to a TV’s remote control as a clicker, because in the early days of television, the control used to make a very loud clicking sound.

The “Tube”

Referring to a TV as “the tube” probably means you are 50 years of age or older. TVs today are flat-panel LCD or Plasma screens as compared to their predecessors which were made with cathode ray tubes (hence the nickname).

Tuning In

This term was applicable when TVs relied on antennas to get good reception. Users literally had to tune the rabbit ears atop a set in order to get a good signal.

Tape

vhsThere are several ways people still use the word “tape,” but many use it when talking about recording their TV shows with a DVR. “Tape” is a relic leftover from the days of actual tapes and VHS players. I am guilty of this particular old term more then any other.

Rewind

This is the universal term for reversing something to watch it again, whether it’s a DVD, a streaming video on Netflix or YouTube. However keep in mind that there is actually nothing to wind anymore because to rewind something requires physical tape.

IP Addressing 101

2013 is history and 2014 is here. Technology news will start to up here again very soon as the new year gets underway. In the meantime did you ever wonder about IP addresses and wanted to learn more about them? Well lets take this slow tech news moment to delve into the basics of IP addressing.

IP Addresses are critical to how our computers and mobile devices communicate.

IP addresses are unique sets of numbers assigned to devices that connect to a network. These sets of numbers are used to send and receive information on the network and to find other devices. An IP address is very much like a home address that others use to send you physical mail and for you to send mail from. Very simply IP addresses are unique identifiers of your location.

While your home or small business router usually handles all IP address assignments via a DHCP (Dynamic Host Control Protocol) server within the router’s software, there are organizations that officially manage and allocate blocks of IP addresses for companies and organizations, just like we do at the Borough of West Chester’s local area network (LAN). IANA (Internet Assigned Number Authority) handles IP addresses allocated globally, typically to Regional Internet Registries. In the Unites States, IP address allocation is managed by ARIN (American Registry for Internet Numbers).

To see what I am talking about check this out and follow along. Be warned – this is very exciting.

IP addresses are represented as a set of dotted decimal numbers. Check it out for yourself and click on the Start button. In the “Search” or “Run” field type in CMD. At the command prompt (which is the C:\>) Type in ipconfig /all followed by the Enter key.

You will see a screen that looks just like the one below (although you may see different numbers) and the yellow highlighted box is merely for this article:

Look at the area in the yellow box. Look for the line IPv4 address. You will see the numbers 192.168.1.4. This is the IP address that my wireless router is assigning to my computer which is connected wirelessly to the router.

This address is used by every other device I have connected on my home network to communicate with my computer.

Look back at the image above. You will see a line that shows my subnet mask is 255.255.255.0.

What does this mean?

Subnets divide networks into groups. You may want to create different groups within a network for giving different users access to different resources, for performance optimization, or for security reasons. Subnet masks tell other devices if a specific device is on a local or remote network, to efficiently route packets.

Another glance back at the image and you will see my gateway address is 192.168.1.1. In most small business and home networks, the gateway address is typically the IP address assigned to the router. The gateway acts almost like a traffic cop, managing the flow of traffic between the Internet and the LAN.
