Transcript of Computer Science Academy
The second day we worked on the same computers that we were assigned. We installed the operating system, changed the boot order, installed a dick, booted the disk, deleted partitions, created new partitions with 41,120, formatted the NTFS, and changed the computer name. As we were doing this, we also kept a repair record of how the machine is acting and if there was any problems.
The purpose of the operating system
Provides a graphical user interface (GUI)
Learning to compress files was interesting to learn. I've never done that before so it was great experience. The task manager is known as the CPU. The CPU gives you the opportunity to check what is running. We got to chance to learn what a C: drive was. Before, I thought it was just a smiley face. The C: drive contains folders and folders of saved information and data.
We learned how to do Binary math. The Binary finds the IP address. The IP address is made up of four octets. They range from 0-255. To get that, you would add all the number together. There are 256 possible because you would add zero. It uses the base 10 numbering systems.
On this day, we learned that if there is a blue screen, and if it is not a virus, 80% of the time its the driver or the ram.
Hubs and switches was one of the topics we had covered. They both look the same, but hubs are the oldest. The hubs makes more traffic and is less secure. Switches determine where the packet goes and has less traffic.
DHCP stands for Dynamic Host Configuration Packet. DNS is the abbreviation of Domain Name Service.
We read an article called Conflicker: The battle of Everyman. Its stated that there was about 130 millions symantec networks. I read that it doesn't take long for a virus to spread, and there are so many ways it could spread.
We learned about web filter, and Proxy.com.
This day we learned about how the blue screen and the debugging mode are both useless. Learning how safe mode is very useful. By starting in safe mode, only the mandatory processes will run. And if you do a virus scan while in safe mode, all the viruses will be detected. F8 is the fastest way to get into safe mode.
There can never be two addresses that are the same on the network card. We also learned the abbreviations of MAC and DHCP. We even got to work on our computers again and we installed JAVA, Adobe Reader, Sophos, and Office 2013. We had also installed the Windows 10. That was part of our lab assignment.
As the day went on, we got into subject of networking. The point of having a network is to control it and change things. It is used for sharing resources. The internet is one of the biggest things that have drove the networking. But it is very complicated and very expensive.
Computer Science Academy
The first day of class was good. We introduced ourselves to the class, took notes about the computer hardware, and the components that were inside the computer. As a class, we were assigned a computer and got the opportunity to look inside a computer and we kept a computer profile to identify what hardware was inside the machine, the brand, the model, type of ram, etc. We learn the abbreviations of BIOS, CMOS, and ESD. Learning what the purpose of a motherboard and how easily it can get ruined. Also getting to see what the motherboard looks like was very interesting. At the end of the day, we took our first review about what we had learned.
During the third day, I learned about the OSI model. It was designed to explain the parts of the networking system. The OSI model has seven layers of data.
Data Link Layer
All of the networking is based on the OSI Model.
The OSI Model uses the MAC address, IP address, Binary, and the connection/connectionless to function.
After learning about the OSI model, we jumped into networks and learned what a Cisco Packet Tracer is. A Cisco Packet Tracer is to create a peer to peer network. Shoring stuff with one another on a peer to peer network. The user decided to have permission for certain viewing.
The Networks we learned about was from the less convenient one to the most modern advanced kind, that we now use today.
For example, if we have an IP address of 192.168.100.30, the router will then be 10101000. The router has to know which network (1) and which part of the local machine address (0). The Router only looks at the subnet mask, it doesn't care about the IP address.
The subnet mask is how we group computers; normally the location.
After the binary math, we learned the abbreviations of MDF and IDF. MDF stands for Main Distribution Frame and IDF stands for Intermediate Distribution Frame. The MDF connects from one side of the world. It also serves and dates. It needs to be secure, limited access, and needs a lot of cooling. But the IDF only deals with switches.
Continuing on during the day, we made our own Cisco Packet Tracer. I learned that the default gateway is always the router, and that the router has a inside and outside address. We followed the steps to activate the router, and once all the routers were active, we started to ping to the different routers.
At the end of the day, as a class, we made our own patch cables and connected them to the RJ47 clips.
On day six, we were introduced to Adobe Photoshop, Adobe Illustrator, and Adobe InDesign. I've never used any of the before so it was fun. It was frustrating at first, then we got the hang of it and it became more clear and understanding.
In the Adobe Photoshop, we edit the color of a picture we chose, we also cut people face out of a photo and placed it on to a carton of eggs. In the Adobe illustrator, we designed a carton hippo. In the Adobe InDesign, we placed a background of our choice, and wrote what we thought of the progams we used.
On day 7, we worked with word press all morning. We designed our own website based on our personality, and our interest. I did a Blog post abut Who I Am. After lunch, we started working on our portfolio. We used Prezi.com to design our portfolio.
This is the last day of the academy. All morning we've been working on our portfolio using Prezi. Its very easy and cool to see all the designs they have to offer. I enjoyed this academy and I learned a lot. And my typing skills have improved.
