Study Notes

Computer Networks

A computer network is a collection of interconnected devices that can communicate and share resources with one another.

Types of Networks

PAN (Personal Area Network): Smallest network type, usually confined to a few meters, designed for personal devices.
LAN (Local Area Network): Limited to a small geographic area, such as a single building or campus, allowing for high-speed connections.
MAN (Metropolitan Area Network): Spans a city or a large campus, larger than a LAN but smaller than a WAN.
WAN (Wide Area Network): Covers a broad area, often a country or continent, connecting multiple LANs.

Network Topologies

Bus Topology: All devices connected to a single central cable (the bus), leading to easier installation but potential drawbacks with cable failures.
Star Topology: All devices connect to a central hub or switch, offering better fault tolerance but higher dependency on the central device.
Mesh Topology: Each device is connected to every other device, providing high redundancy but requiring more cabling.

OSI Model

A framework used to understand and implement network communications in seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical.

IP Addresses

A unique numerical label assigned to each device on a network, used for identification and communication within networks.

Subnet Mask

A subnet mask is crucial for defining which portion of an IP address represents the network and which part represents the host.

Types of IP Addresses

Two main types of IP addresses:
- Static IP Address: Fixed address that does not change.
- Dynamic IP Address: Assigned by a DHCP server and may change over time.

Email Protocol

SMTP (Simple Mail Transfer Protocol): Protocol specifically used for sending emails, differentiating it from file transfer (FTP), domain name services (DNS), or web page transfers (HTTP).

Router Functions

A router connects different networks, directing data packets between them, establishing paths to enable communication across diverse networks.

Wireless Connectivity

Access Point: A device that provides wireless network connectivity, allowing devices to connect to a wired network.

Mesh Topology Truth Value

In a mesh topology, it is true that every device connects to every other device, offering minimal downtime and robust communication.
