1. PAN, LAN, MAN, WAN By Zach and Salah 9BA

2. PAN (Personal Area Network) PAN is a small network that interconnects technology devices within a limited range of just a few meters. This type of network is designed to enable devices in an office environment to communicate and share resources, data and applications either wired or wirelessly.

3. LAN (Local Area Network) A local area network (LAN) is defined as a connected environment spanning one or more building (Normally in a 1 kilometer radius) that links computing devices within close proximity of each other by using ethernet and Wi-Fi technology.

4. WAN (Wide Area Network) WAN (Wide Area Network) is a large network of information that is not tied to a single location. WANs can facilitate communication, the sharing of information and much more between devices from around the world through a WAN provider.

5. MAN (Metropolitan Area Network) A metropolitan area network (MAN) is a computer network that connects computers within a metropolitan area, which could be a single large city, multiple cities and towns, or any given large area with multiple buildings.

6. Advantages and Disadvantages of PAN, LAN, WAN, MAN Advantages Disadvantages PAN LAN WAN MAN

7. Advantages and Disadvantages of LAN Advantages: Simple and reasonable cost: The primary benefit of the local area network is that is immediate and easy to set up and also its price is minimum. LAN allows for the sharing of software programs, allowing for a single licensed program to be used by any device on the network, eliminating the need for costly licenses. Data protection ensures secure storage of information on servers, allowing quick updates or removal of data on a single computer, ensuring access to new information for other devices. The LAN-connected system offers high-speed direct communication through ethernet cabling and LAN models, with the most common speeds being 10Mbps, 100Mbps, and 1000Mbps. Disa dvantages: Local area networks are exclusively used in buildings or apartment complexes and cannot be used in larger areas. Information security vulnerability created: A technological error could allow unauthorised users to get data from the server equipment if it is not programmed appropriately. Problems like server privacy come up. Data sharing via external source: Since transportable media, such as CDs and pen drives, cannot be conveniently used on all networked computers, sending files from outside the network is challenging and time-consuming. Maintenance and management: To guarantee optimum operation, LANs need to have regular maintenance and management. This may be expensive and time-consuming.

8. Network Topologies Topology Logical layout of wires and equipment Choice Effects Network performance Network size Network collision detection

9. Network Topologies Bus To pology Also called linear bus One wire connects all nodes Terminator ends the wires Advantages: Easy to set up Small amount of wire Disadvantages: Slow Easy to crash

10. Mesh Topology N etwork setup where each computer and network device is interconnected with one another. Advantages of Topology:

11. Scenario 1: A research laboratory needs a group of three computers connected together to share resources. The network will be temporary because it is for a short experiment. The computers will be in a secure room and each user will have access to each computer, this means data transfer security isn't a high priority. The majority of the scientists' funding has been spent on the experiments so there are very limited funds to create this network Answer: They should use a bus topology as it is simpler to set up and it is for a short experiment and the networks doesn’t need to be that complex.

12. Scenario 2: A h omeowner is building their dream house. There are four bedrooms and two offices in the new home. The homeowner wants a stable connection from each room to a central location. The central location will also be connected to the internet and a printer. The homeowner doesn't require a direct connection from room to room but would like the ability to connect through the central location on occasion when the family might want to shore photographs or videos with each other through the network. They have a reasonable budget but want to avoid any unnecessary costs. The homeowner Answer: Star topology because the homeowner needs the network to be in a central location in the house

13. Scenario 3: A new tech startup company has an office space that currently requires 20 users to be connected to a network. There will be a mixture of laptops and desktop computers. They also require shared, high-speed internet access and a shared laser printer. The network must be fast and stable. It should also be easy to add new devices to the network without having to shutdown the network or compromise on stability and speed. Users of the network will need to be in constant contact with other users in the network through an internal messaging system, this must be fast and reliable to increase productivity The tech company has two wealthy backers and they have an excellent budget for setting up their network. Answer: Ring Topology

14. Scenario 4: A small printing company has been using stand alone computers (computers not connected to a network) for several decades. They have five computers and three industrial printers. They would like to upgrade their IT infrastructure to enable all computers on the network to share a connection with the printers. They also want the ability to share an internet connection and to send data to other computers on the network. The network will be in a secured location and not accessible to the public. transfer must be fast because they will be sending large amounts of data to the industrial printers. They also would like the option to expand the network in the future they need to. The company doesn't have a large budget for this project. Answer: Mesh Topology because the printing company wants all the data to transfer fast.

15. How do these devices aid in the flow of communication in a network? -Modem: modems are essential for enabling devices to communicate with each other and access the internet, serving as the bridge between digital devices and analog transmission mediums. - Router: routers are essential for managing and directing data traffic within and between networks, ensuring that devices can communicate effectively and securely. 4o mini:routers manage data traffic, enhance security, and facilitate communication between devices and networks. -Switch: switches improve communication within a network by managing data flow, reducing congestion, and enhancing performance. -Hub : A hub is a networking device that connects multiple computers or other network devices together. -Printer: prints and farts -Computer: computers are essential for generating, processing, and communicating data within a network, enabling various applications and services that connect users and devices. -Server:
