Study Notes
Introduction to Computer Network
- A computer network is a group of interconnected devices, using transmission mediums like wires or cables.
- The purpose of a computer network is to share data between devices.
- Computer networks consist of two or more interconnected computer systems.
- A network connection can be established using either cables or wireless media.
Advantages of a Computer Network
- Connects multiple computers for sharing information.
- Enables sharing of resources like printers, scanners, and emails.
- Allows for faster information sharing.
- Offers electronic communication, which is often more efficient and less expensive than traditional methods.
Basic Components of a Computer Network
- Protocol: A set of rules governing communication between devices.
- Sender: Device originating the data.
- Receiver: Device receiving the data.
- Message: Data being transferred.
- Transmission Media: The pathway for data transfer (e.g., cables, radio waves).
Transmission Media
- Physical paths for data transmission between devices.
- Examples include: wires, cables, radio waves.
Protocols
- Protocols are sets of rules that govern how devices communicate.
- Without protocols, devices can't communicate reliably.
- Protocols ensure reliable data communication between devices.
Switches
- Connect devices within a network (e.g., computers, printers).
- Act as controllers in a campus or building network.
Routers
- Connect multiple networks.
- Allow for efficient data sharing.
- Act as dispatchers to find the best routes for data transmission.
Servers
- Computers storing shared files and programs for network users.
- Provide access to network resources.
Transmission Media
- Various types exist, including coaxial cables, twisted-pair wires, and fiber optic cables.
Access points
- Allow wireless device connections to a network.
- Provide flexible connectivity and easier connection to mobile users.
Shared data
- Data shared among clients (e.g., files, printer access, programs, emails).
Network Interface Card (NIC)
- Card that allows a computer to communicate with the network.
- Sends, receives, and controls data flow between the computer and the network.
Local Operating System (OS)
- Software a personal computer uses to access local files, printers, and CD/DVD drives.
Network Operating System (NOS)
- Software for computers and servers that allows communication.
- Enables communication between computers on a network.
Hubs
- Network devices in data transmission.
- Act as a central connection point for other devices.
- Transmit data to all attached devices.
LAN Cables
- Ethernet or data cables used to connect devices to a local area network (LAN).
OSI Model
- Open Systems Interconnection model.
- Allows for the standardization of communication protocols.
Network Topology
- Physical or logical arrangement of devices in a network.
- Bus Topology: All devices share a single communication line, potential single point of failure.
- Star Topology: Devices connected to a central hub using point-to-point connections.
- Ring Topology: Devices form a closed loop, with each device connected to two others.
- Mesh Topology: Devices are connected directly to each other, often in a complex configuration.
- Tree Topology: A hierarchical structure of interconnected devices and logical network layers.
- Hybrid Topology: Combines different topologies, creating a combined network structure.
Peer-to-Peer Architecture
- All computers in the network are connected, with each computer sharing resources.
- Every computer acts as a client and a server.
Client-Server Architecture
- Central server manages data and resources.
- Client computers request services from the server.
- Efficient for large networks.
Internet Service Providers (ISPs)
- Companies providing internet access.
- Offer various services like internet access, domain name registration, dial-up access, and leased lines.
VSAT (Very Small Aperture Terminal)
- Microwaves transmitted between ground stations and satellites.
- Often used for remote areas lacking wired infrastructure.
Types of Networks
- Personal Area Network (PAN): Connects devices within a personal space, like smartphones and computers.
- Local Area Network (LAN): Connects devices within a limited area, like a home or office.
- Metropolitan Area Network (MAN): Spans a metropolitan area (city or a region)
- Wide Area Network (WAN): Connects devices across large geographical areas.
