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.
By default, 10 computers can be joined to the domain by both users and administrators. As long as a user is authenticated against the Active Directory, he or she can add up to 10 computers to the domain.
While this one posses as an advantage for smaller companies, it is not a desirable feature for bigger companies since they have to control more tightly who can add machines to their domain.
