Week 7 - Chapter 4

Intro

In this week's class, we explored the world of networks; more specifically what they (networks) are and how they have influenced business practices. Let's dive in:

4.1 What is a computer network?
- A computer network enables data transmission by connecting devices via communication channels.
- Networks have a need for more bandwidth in order to achieve faster functioning (measured in bits per second.)
- Two different types of networks: local area networks (LAN) and wide area networks (WAN).
- WANs connect numerous LANs, separating them from one another.

4.2 Network fundamentals
In class, we discussed how networks transmit information using two sorts of signals: analogue and digital.
Analogue signals: Continuous waves that transmit information through amplitude and frequency changes.
Digital signals: Made consisting of discrete pulses that can be represented in binary as on (1) or off (0).
Modems are critical instruments for transforming these signal kinds. Analogue transmissions, such as AM, are less susceptible to interference from adjacent channels, although FM signals can travel longer distances.

4.3 The internet and the world wide web
The internet serves as a "network of networks," allowing individuals and organisations throughout the world to instantly access and exchange data at a minimal cost, making it critical for modern enterprises. Some methods of connecting to the internet could include:

- Cable modem: via the coaxial line of your cable TV. may experience poor speed if numerous neighbours are using the internet concurrently. - Wireless: Extremely practical and promotes the adoption of wireless broadband - Satellite: Where cable and ADSL are unavailable, access

4.4 Network Applications

We utilise and apply networks in many ways, this mainly includes aspects such as:

• Discovery: Enabling people to obtain information from several databases.

• Communication: Users can connect globally in record speed using email, call centres, and chat rooms.

• Collaboration: Users can work together effectively to complete tasks.

• E-learning and distance learning: Because the internet is interactive, people can conduct their own research.

• Virtual universities: Online access has made universities that were previously only available in person available.

• Telecommuting: Enables the ability to work remotely, mostly from home but from other locations as well that's outside the usual traditional office.
