Q.  Explain any two types of SBC in detail. 

Answer: 

The Two types of SBC are as follows:

Raspberry Pi :

Raspberry Pi is a low-cost, credit card-sized SBC that was first introduced in 2012. It is designed and manufactured by the Raspberry Pi Foundation and is widely used in educational, hobbyist, and DIY projects. Raspberry Pi boards feature a Broadcom ARM processor, RAM, and various input/output interfaces such as USB, Ethernet, HDMI, and GPIO pins.Raspberry Pi is known for being user-friendly, with a simple setup process and a range of software tools and programming languages available.

Beagleboard :

BeagleBoard is a more powerful SBC that is designed for advanced applications, such as robotics and industrial automation. BeagleBoard is an open-source hardware platform that was first introduced in 2008 and has evolved over time with different iterations such as BeagleBoard-xM, BeagleBone, and BeagleBone Black. BeagleBone boards feature a more powerful ARM processor, more RAM, and a range of input/output interfaces, including Ethernet, USB, HDMI, and GPIO pins.BeagleBoard is known for being flexible and customizable, with support for a wide range of software and operating systems.

Q. Give the advantages and disadvantages of SBC.

Answer:

Advantages of SBCs:

1) Small size and low power consumption
2) Can be easily integrated into existing systems
3) More cost-effective than traditional computers for certain applications
4) Ideal for low-power and low-cost applications

Disadvantages of SBCs:

1) Limited computing power compared to traditional computers
2) May require additional peripherals or components for certain applications
3) May be more difficult to set up and use compared to traditional computers

Q. Explain different types of Network Access devices used for SBC along with their features.

Answer:

There are various types of network access devices that are commonly used in conjunction with SBCs. Devices are as follows:

Ethernet Switch:

Ethernet switches are network devices that connect multiple devices together on a local area network (LAN). They provide connectivity by directing traffic between devices based on their MAC addresses.

Router:

Routers are network devices that connect multiple networks together. They provide connectivity by directing traffic between networks based on their IP addresses. Routers are available in a range of sizes, from small home routers to large enterprise routers with advanced features such as VPNs, firewalls, and load balancing.

Wireless Access Point (WAP):

A wireless access point (WAP) is a network device that allows wireless devices to connect to a wired network. They provide wireless connectivity by creating a wireless network (also known as a Wi-Fi network) that devices can connect to. WAPs are available in a range of sizes and configurations, from small home WAPs to large enterprise WAPs with advanced features such as multiple SSIDs, VLANs, and roaming.

Modem:

A modem is a network device that provides connectivity to the internet. It connects to a WAN (wide area network) connection, such as cable or DSL, and converts the signals into data that can be used by a computer or other network device.
