<h3>What is a 
mobile computing device?</h3>
Any device that was built using mobile parts, such as mobile hardware and software, is referred to as a mobile computing device. Portable devices that can function like a typical computing device in terms of operation, execution, and provision of services and applications are known as mobile computing devices.
Portable and handheld computing devices are other names for mobile computing devices.
Modern handheld devices that have the hardware and software needed to run common desktop and Web applications are generally referred to as mobile computing devices. Similar hardware and software elements found in personal computers, such as processors, random memory and storage, Wi-Fi, and an operating system, are also found in mobile computing devices. They are made specifically for mobile architecture and portability, which sets them apart from PCS.

Answer:
a. 1 is a packet, 2 is data, 3 is a frame.
Explanation:
And what is not  mentioned is segment which used TCP/UDP and is part of Transport layer. The packet carries the destination and sender IP address, and is part of the Network Layer. The frame has the Mac address of destination device and senders device and is part of data link layer. 
Hence segment has no IP address, hence b. is not correct. Also, data cannot have the IP Address, and Frame has the MAC address, Hence, the above answer. And this arrangement is part of Data Encapsulation.
Also keep in mind data can be anything like a series of bits, or any and it can or not have a header.
 
        
             
        
        
        
The best scenario is when a program suffers from frequent
page faults. In the situations when a kernel thread experiences a page fault,
another kernel thread can be switched in; something a single-threaded process
will not be capable of doing. Another best circumstance is when a program has
to wait for other systems events.
