The video also compares wired and wireless networks, detailing the benefits of each, such as faster speeds and security for wired networks, and flexibility and cost-efficiency for wireless. It concludes by describing wireless technologies like Bluetooth, Wi-Fi, and WiMAX, and their respective network types: PAN, LAN, MAN, and WAN.

Takeaways

• 😀 Wired networks (jaringan kabel) use physical cables to connect computers and share data.
• 😀 There are three main types of network cables: coaxial, twisted pair, and fiber optic.
• 😀 Coaxial cables are mainly used for TV connections and are now largely obsolete for computer networking.
• 😀 Twisted pair cables come in three types: STP (shielded), FTP (foiled), and UTP (unshielded), with varying levels of protection against interference.
• 😀 UTP cables are most commonly used in LAN and telephone networks, but are sensitive to high-voltage electricity.
• 😀 Fiber optic cables provide high-speed, stable connections and are used in large-scale networks like MAN and WAN.
• 😀 The advantages of wired networks include affordability, high security, faster connections, and easier installation.
• 😀 Disadvantages of wired networks include untidy cables, limited reach, and security risks if the cables are cut.
• 😀 Wireless networks (jaringan nirkabel) use radio waves or infrared signals to connect computers without physical cables.
• 😀 Types of wireless networks include PAN (Bluetooth, infrared), WLAN (local area network), MAN (metropolitan area network), and WWAN (wide area network using mobile technologies).
• 😀 Wireless networks offer advantages such as wide coverage, easy relocation, and flexible placement, but have drawbacks like higher costs and lower data security.

Q & A

What is a wired network?

A wired network is a computer network that connects computers using physical cables, allowing them to exchange information or data. It typically uses network cables to create the connection.

What are the three main types of network cables mentioned?

The three main types of network cables discussed are coaxial cables, twisted pair cables, and fiber optic cables.

What is a coaxial cable used for?

Coaxial cables are used to connect televisions with antenna devices, and they can also be used to set up computer networks or as radio transmission lines.

What is the main limitation of coaxial cables?

The main limitation of coaxial cables is that they offer limited performance and network range, making them less common for modern internet users.

What is the difference between STP, FTP, and UTP cables?

STP (Shielded Twisted Pair) cables are designed to protect against electromagnetic interference, making them ideal for large companies. FTP (Foiled Twisted Pair) cables have a foil layer that offers some protection against interference, while UTP (Unshielded Twisted Pair) cables lack any shielding and are more vulnerable to high electrical voltages.

What is a fiber optic cable used for?

Fiber optic cables are used for high-performance and high-quality network connections, offering fast, stable internet. They are typically used in Metropolitan Area Networks (MAN), Wide Area Networks (WAN), and Local Area Networks (LAN).

What are the advantages of wired networks?

The advantages of wired networks include relatively low cost, high security, better performance, higher bandwidth, easy installation, and faster network connections compared to wireless networks.

What are the disadvantages of wired networks?

The disadvantages of wired networks include cluttered cables, limited reach, challenges in network expansion, and the loss of security if cables are cut.

What is a wireless network?

A wireless network is a system that enables communication between computers without the need for cables. It uses transmission media such as radio waves, microwaves, or infrared light.

What are the different types of wireless networks?

The types of wireless networks include Wireless Personal Area Networks (WPAN), Wireless Local Area Networks (WLAN), Wireless Metropolitan Area Networks (WMAN), and Wireless Wide Area Networks (WWAN), with technologies like Bluetooth, Wi-Fi, and WiMax used for each.
