Introduction to networking

Binary numbers 1-15

1=1
2=10
3=11
4=100
5=101
6=110
7=111
8=1000
9=1001
10=1010
11=1011
12=1100
13=1101
14=1110
15=1111

Activity 5 summary

In this activity I learned how to transfer binary numbers into decimal conversions. Although at first it was confussing it came out to be really easy if you just pay attention.

Activity 5 binary

Activity 4 summary

In this activity we were suppose to find the definitions for physical connection, physical address, network address, default gateway, and DNS server. Then we had to get screen shots of general/support tabs and IPconfig/all. Then we had to post the Ip Address, N mask, D/F Gateway,and the DNS Server Address.

Post of cdm config

Ip Address- 10.57.119.60
S/N mask- 255.255.255.0
D/F Gateway- 10.57.119.1
DNS Server Address- 10.57.2.37

Screen shot of General/ support tabs

Activity 4 definitions

Physical Connection- A physical connection is like a wire. It determines what kind of cable is used

Physical Address- A physical address is something such as a social secritey number. It is just a computer address

Network Address- A network address is like a phone number. Its numbers that lead to the site you want to goto.

Defaut Gateway- This is a door way to the rest of the internet

DNS Server- This is like a phone book to everywhere on the web

Activity 3 january 28 2010

Today we discused input and output devices such as keyboards and TVs. We also discussed operating systems and networking applications. Then we made a blog. In this blog we found pictures or took screen shots of the input and output devices, Operating systems, and networking applications.

Network Applications

Opperating systems

Input and Output

Input 1. Keyboard 2. Mouse 3. TV remote
Output 1. TV 2. Computer Monitor 3. Speakers

Journal/summary activity two jan 26

I am going to find the 7 defintions of a osi-tcp. Then i will have a chart explaining it and a summary also explaining it.

Defintion

OSI Physical- The Physical Layer is the first and lowest layer in the seven layers of the OSI models. It defines the eltrical, mechanical, and other things. It transmits raw bits rather than logical data packets over a physical link connecting network nodes.

Data Link- The data link transits data accross a physical link. The data link is used with the physical adressing and flow control.

Network- This is a layer that provides connectivity on geographically driverse networks. It is concerend with the Ip.

Transport- This layer segments data into a data stream. It provides establishment, maintance and information flow.

Application- This layer is closest to the user. Provides networking to the users applications also it does not provide service to any other OSI

OSI

In the OSI reference model, there are seven numbered layers, each of which illustrates a particular network function. It describes a method of how information or data moves from one computer to another computer. It also is considered the best tool available for teaching people about sending and receiving data on a network and provides a framework for network discussions.

Conclusion

In Activity 2 we had to get a graphic of the OSI-ICP Comparrison charts. We had to define the 7 layers of the OSI. I am looking foward to the second semester of learning in this class.
