The main challenges facing by operating system between user mode and kernel mode are as follows:
The size of each parameter which is passing to make system calls must not exceed to the size of registers. The parameters should not be more than six.To deal with the above problem, the parameters are written in the registers before executing system call.
Further explanation:
User Mode: In this mode, CPU has limited access to manage the memory and also access of peripheral devices (network cards and disks) is not permissible. The CPU can be taking away from a program at any tie.
Kernel Mode: The CPU has ability to manage the memory and have access of peripheral devices. The CPU can switch from one program to other program in this mode.
Hence, if program is running in user mode then it prevents to access the other programs.
Switching from User to Kernel Mode: First, set the values with parameters in the registers and execute the trap instruction. Just after that, CPU switches to kernel mode and jumps to the memory location. These instructions are known as system call handler or trap which reads the instructions and perform in kernel mode. After the system call, OS resets the mode to user mode and hence now it can now perform both simultaneously.

D.font
Answer:
C.animation
Explanation:
You can animate text, images, shapes, tables SmartArt graphics and other objects in your interactive presentation.
Effects can make an object appear, disappear, or move. They can change the size or color of the object.
You can apply more than one animation to a single object. Just select the object again and apply an additional effect.
Each animation effect is represented on the slide by a number Animation number next to the object and this number indicates the order of playback. If there are two animation effects set to play at the same time, they will be represented by a numbered stack.

A dhcp server is a server that uses software and dhcp to automatically assign a(n) ______ address from a pool of possible addresses
A DHCP server uses the Dynamic Host Configuration Protocol to allocate dynamic IP addresses from a pool to client devices on a network, streamlining the IP address management process.
A DHCP server is a server that uses software and the Dynamic Host Configuration Protocol (DHCP) to automatically assign a dynamic IP address from a pool of possible addresses to client machines on a network. This process is essential for simplifying the management of IP addresses.
The DHCP server ensures each client has an IP address that is unique on the network, which is necessary for communication with other computers. Additionally, the DHCP server can provide other configuration details such as the subnet mask, default gateway, and DNS server information.

The use of computer hardware and software to analyze biological data, such as dna sequence comparison data, is known as ________.
Bioinformatics is the field that combines biology, computer science, and statistics to analyze and interpret biological data, such as DNA sequences, using computer hardware and software.
What is Bioinformatics?
The use of computer hardware and software to analyze biological data, such as dna sequence comparison data, is known as bioinformatics. This interdisciplinary field combines biology, computer science, and statistics to manage and analyze the large amounts of data generated by genomic sequencing, gene expression profiling, and determination of macromolecular structures. Essential to modern biology, bioinformatics involves a range of activities, including genome annotation, sequence comparison, and evolutionary analysis. With the advent of high throughput scientific techniques, such as DNA sequencing, researchers have access to vast datasets necessitating the development of efficient computational tools to align and analyze sequences. By comparing DNA sequences with those in databases like GenBank, scientists can conduct sequence homology studies to estimate evolutionary distances and construct phylogenetic trees, dramatically improving our understanding of biological evolution and species relationships.
