Job Shadowing

I job shadowed Promotional Partners' Olivia Scott from eight in the morning to twelve. They worked on putting logos and designs on items for companies and sometimes individual families. They put them on pens, shirts, mugs, flags, stickers, everything!
I got there a few minutes past eight to find that (surprise!) Trevor from AOIT was already there. He had gotten to Historic Downtown Apex shortly before me to find that all the doors to Promotional Partners were locked. But then, when I was testing the doors just to make sure that they were locked, Ms. Olivia Scott arrived and took us upstairs to her office, right over Anna's Pizzeria. She showed us the office rooms, the restrooms, and the two storage rooms where they put example products in case a client had no idea what they wanted. She also added that they'd help make the AOIT shirts. Indeed, later in the day, I found a shirt just like mine in that room, just without the embroidery.
After that, she told us that she pitied the two of us. Promotional Partners, she explained, did most of their work online, writing out emails. Her husband worked on financing, Miranda was there to design logos and things of that nature, while another woman's main job was to check if the manufacturing companies had the materials for the supplies they wanted to make. I didn't meet her. She only came in the afternoons.
I also sort of forgot what Olivia did, except she mentioned emails and lists. Maybe it was to identify what that client wanted?
After the tour of the three rooms, she handed us some magazines and told us that we could sit in the seats in front of her desk and read them. Trevor was a much faster reader than me and he kept on staring off into space or eyeing the one that he hadn't read on my lap. The magazines were mostly about ideas for promoting businesses. There were lots of pens and even a few pages on Fall Fashion, in case the companies wanted to put their logo on some of them. I was struck in awe at how cheap everything was. The next time I get pens at Target, I'm going to compare them to the few cents of the ones in the magazines!
While we were busy reading them (or at least I was) her husband Keith walked in and told us that we were doing a fine job acting like those magazines were interesting. Miranda, a young woman who said she'd graduated from AOIT, agreed with him. I wasn't looking at the the time, you see, so I couldn't tell you everything in detail. But some time between eight thirty and ten, Miranda showed us some Honda stickers she was making. They went something like, "Remember to get an oil change when your oil is at 15%!" split into three lines. There was "Automobiles" under that and "Honda" tucked under "mobiles". The "Automobiles" was a cerulean like blue while the the third line on the sticker was a bright red.
After that, we got back to reading magazines for a while. But Miranda seemed to have warned up on us and put up some music on the radio by the door. She also had Trevor try some special-vision glasses of whatever. They allowed you to view a Youtube video as if you were actually in it. Trevor's phone case didn't fit in the phone slot so Miranda lended him hers and he watched a roller coaster ride.
After that, I dragged Trevor along so we could explore the building. Olivia had gone to a to a parade meeting while Keith seemed to have disappeared. It seemed to be from ten to eleven. We went downstairs to Anna's Pizzeria and to all of the storage rooms.
It was then that Miranda showed us how she made logos and things like that and Keith explained how he worked with the budget.

Lesson 11- Internet

What is the Internet?
     The Internet is the world's largest WAN (Wide Area Network) and is made up lots of smaller networks. It connects more than two billion people together by delivering information to them. It's very young, being introduced to the public for less than three decades. There are lots of rules for the Internet and lots of parts to it too. The Internet can also be accessed through apps on a phone.

What is a protocol?
     A protocol would be a set of rules for any given thing. In this case, it would be the Internet. The who basic types are TCP (Transmission Control Protocol) and IP (Internet Protocol). The first parts of Internet's URLs would be the "http://" part, which would be needed for someone to view the page. They can also be used as a communications protocol for private networks like an intranet or an extranet. 

What is DNS?
     Domain Name Services (DNS) help translate addresses. Without them, there would be no Internet. They basically are like a phone book and they look for the information that you type. For example, if you type a website name, they will look for the IP address. If they don't have it, they'll ask other DNS with they have the information.

Explain what an ISP is and what it does?
     Internet Service Providers (ISPs), provide Internet. They basically use routers that connect with LAN's and then WAN's and then onto the Internet. It's what the data travels through and they often skip around from router to router before finding their destination. Some examples of ISP would be AT&T, IBM, and Netcom. Sometimes they can also be called IAP, "Internet Access Providers", or another version of ISP, "Independent Service Provider".

What is a Ping and Firewall?
     Pings are used to determine if the connections to the machines are working or not. They check the network connections. Firewalls protect your computer from Internet threats and can be both hardware and software. Firewalls can be customized to their own rules. Some examples of what they block can be malicious websites or virus'.
