Main ideas / lessons conveyed

  • Setting up a small network requires planning based on needs, preferences, and a budget.
  • You must define your requirements across:
    • Hardware
    • Software
    • Internet connection
  • You need to choose:
    • Wired vs. wireless connectivity
    • A networking strategy: client-server vs peer-to-peer
    • A security approach
  • After planning, you must budget for all necessary purchases and then implement configuration steps.

Assumptions described in the video

  • The network is assumed to have about 10 computers (e.g., desktop, laptop, tablet).
  • Additional peripherals are included, such as printers and scanners.

Networking model / strategy assumed

  • Client-server model is used, with:
    • A server for data storage, application services, file sharing, and security
    • Support for both wired and wireless connections

Detailed instruction / methodology (step-by-step)

1) Assess needs and plan

  • Identify requirements in:
    • Hardware
    • Software
    • Internet connection
  • Decide connectivity method:
    • Wired or wireless
  • Decide networking strategy:
    • Client-server (as assumed)
    • or peer-to-peer
  • Identify how the network will be secured
  • Allocate a budget for required components

2) Hardware requirements (what you need)

  • Computers/devices: desktops, laptops, tablets
  • Peripherals: printers, scanners
  • Network interface cards (NICs):
    • Needed for devices that don’t already have built-in network interfaces
  • Server:
    • Manages applications, data storage, communication, and network security
  • Switch:
    • Connects devices on the local network (LAN)
  • Network cables (for wired connections)
  • Wireless access point:
    • Allows wireless devices to join the network
  • Modem/router + telephone/cable line
  • Internet service provider (ISP) account for internet access

3) Software requirements (what to install/use)

  • Firewall (protects against hackers)
  • Antivirus and anti-spyware (protects against malware)
  • Email account (sending/receiving electronic mail)
  • Web browser (accessing web pages)
  • Server configuration tasks:
    • Install common software onto the server
    • Set up user privileges so users can access:
      • their own area
      • shared/common areas

4) Setup / configuration steps (as described)

  • Connect wired devices:
    • Plug one end of each network cable into a device’s NIC
    • Plug the other end into the switch ports
  • Set up wireless access:
    • Connect/configure a wireless access point to the switch
  • Set up ISP account
  • Connect router to the line:
    • Plug one end into the telephone/cable line
    • Plug the other end into the telephone/cable box
  • Get internet connection installed via the ISP
  • Connect LAN to the internet:
    • Connect the device that links the LAN (described as connecting the router/switch path) to allow internet access
  • Install and configure software on devices/server:
    • Firewall, antivirus, anti-spyware
    • Configure web browser access for each device
    • Set up email accounts for users
