A key physical design element is the UI, which describes how are users interact with a computer system.
The four components of computer are explained clearly.
<u>Explanation:</u>
- Hardware is the electrical physical parts that a computer system needs to function. It organizes all the process by a circuit board that operates within a PC or laptop; built with the "motherboard", "graphics card", "CPU (Central Processing Unit)", "ventilation fans", "webcam", "power supply", and so on. Without hardware, there is no means of running the necessary software that makes computers so valuable.
- Software is a program that facilitates a computer to execute a particular task, as objected to the hardware. Computer software has to be "stored" into the computer's storage (such as a hard drive, memory, or RAM). Working computer systems segment software into three major classes: system software, programming software, and application software.
- A user is a person who handles a computer or network service. Users of computer and software output regularly require the technical expertise needed to fully know how they operate.
- Data is defined as bases or figures, or knowledge that's saved in or utilized by a computer. This data will be in the form of text documents, images, audio clips, software programs, or other types of data. Computer data may be prepared by the CPU and are saved in files and folders on the hard disk.
Answer:
D. return str.substring(0, 1) + removeDupChars(str.substring(1));
Explanation:
The logic here is following:
If the there are consecutive duplicate characters, return the removeDupChars method. The parameter of the removeDupChars method is a string, but the duplicate of the first character is removed from the string. The else-if part of the program does this job.
If the consecutive characters are not duplicated, return the first character of the string and the removeDupChars method. The parameter of the removeDupChars method is the rest of the string characters. The else part of the program does this job.
When the length of the str becomes one (or when the str is null), the program reaches its base and returns the str. The if part of the program does this job.
