Networks

COMP 1010 Home > Networks

Introduction A computer network is a set of computers that can communicate with each other. This communications can be achieved using Ethernet cables or wireless. have changed the way society communicates information through email, video, and websites like Facebook, YouTube and Twitter. This topic continues to be in the forefront of research as newer technologies and algorithms are required to transfer these large amounts of data from point to another point. Areas of research such as wireless ad-hoc networks and peer-to-peer networks are continuing to be in the forefront of this research.

Courses

• Computer Networks I
• Computer Networks II
• Computer Security
• Cryptography and Cryptosystems

Career Opportunities

• Network Administrator : network administrators configure and manage LANs(Local Area Networks) and sometimes WANs(Wide Area Networks)
• Network (Systems) Engineer : network engineers focus primarily on system upgrades, evaluating vendor products, security testing, and so on
• Network (Service) Technician : focus more on the setup, troubleshooting, and repair of specific hardware and software products. Service Technicians in particular often must travel to remote customer sites to perform "field" upgrades and support
• Network Programmer/Analyst : write software programs or scripts that aid in network analysis, such as diagnostics or monitoring utilities
• Network/Information Systems Manager : supervise the work of administrators, engineers, technicians, and/or programmers. Network / Information Systems Managers also focus on longer-range planning and strategy considerations

I wanted to upgrade the speed and reliability of the wireless signal at home, but I knew almost nothing about networks. I started by doing some research on routers, looking for faster download speeds and stronger signal. I decided on a router but now I had to set it up to work at home while still ensure my network was secure. So, as I researched the router settings related to security, I discovered how to enable features like MAC Address Filtering, restricting access by a password, and encrypting the data that is being transferred from the router to the computers on the network. It was all very interesting to learn how a typical network works and how to make my computers less vulnerable to attacks.
