TCP/IP & Security for Wireless & Mobile Networks - Chapter Summary
In this chapter, you'll find a series of lessons on TCIP/IP and security for mobile and wireless networks. Some of the topics covered include communication protocols, layers in the TCP/IP network stack and use of this protocol for mobile networking. The lessons are self-paced and accompanied by multiple-choice quizzes that allow you to reinforce concepts as you study. If you have any questions along the way, reach out to one of our experts for assistance. Once you complete this chapter, you should be ready to achieve the following objectives:
- Detail the function of the layers in the TCP/IP network stack
- Use the TCP/IP protocol for mobile networking
- Outline the problems and solutions involved with wireless transmission of TCP/IP packets
- Discuss the analysis and detection of mobile malware
- Detail protection from and removal of mobile malware
- Explain causes of noise and poor signal strength in wireless networks
- Identify problems with TCP/IP in a mobile network
1. What is Communication Protocol? - TCP/IP & Explanation
In this lesson, you will learn about 'The Internet's Protocol Suite', composed of the Transmission Control Protocol (TCP), and the Internet Protocol (IP); abbreviated as TCP/IP. Lesson highlights include: TCP and IP defined, how TCP/IP became the foundation for today's Internet communications and how the five layers of the TCP/IP model compares with the seven layers of the Open System Interconnection (OSI) model.
2. Layers in the TCP/IP Network Stack: Function & Purpose
The Transmission Control Protocol/Internet Protocol (TCP/IP suite) governs the Internet and the data transported over it. In this lesson, we take a closer look at the organization of TCP/IP, study its divisions and the function they perform.
3. Using the TCP/IP Protocol for Mobile Networking
The traditional design of the TCP/IP protocol suite mainly supports wired networks. Mobile or wireless networking requires additional requirements over these traditional protocols. Let us discuss the problems in TCP/IP and their solutions for wireless networking.
4. Wireless Transmission of TCP/IP Packets: Problems & Solutions
In this lesson, you will be introduced to some of the common problems occurring in TCP/IP packets like bit errors, handoff errors, congestion, re-ordering errors, errors caused by delays, and bursts of errors. How they are typically dealt with in order to insure packet delivery in the wireless network will also be discussed.
5. Mobile Malware: Analysis & Detection
One of the most important ways to lessen the danger caused by mobile malware is to be able to detect it early through device analysis. This lesson shows you what to look for.
6. Mobile Malware: Protection & Removal
If you think that your data is safe because it is on a mobile device, think again! Mobile malware has arrived in the last few years as a legitimate concern to the security of your data.
7. Internet Packet: Definition & Explanation
In this lesson, we'll define Internet packets and describe Internet packet construction. We'll also discuss the 14 fields comprising a typical data packet and how you can test for and correct packet loss problems, such as signal loss.
8. Noise in Wireless Networks: Causes & Resolution
Noise can make it hard to hear someone you're trying to talk to. You may not be able to understand what they're are saying and you may even miss whole parts of the conversation. The same can happen in wireless networks. In this lesson, we will discuss what noise is in terms of a wireless network and how to resolve the issues caused by it.
9. Poor Signal Strength in Wireless Networks: Causes & Remedies
Poor signal strength from your wireless network can make surfing the internet and downloading content a frustrating experience. In this lesson, you'll learn about causes and remedies of signal strength issues.
