Which Of The Following Refers To The Case That Contains And Protects The Motherboard?

Which of the following refers to the case that contains and protects the motherboard?

1. A) memory manager
2. B) CP case
3. C) system unit
4. D) encapsulator

Answer: The system unit is referring to the case that contains and protect the motherboard, it does not have the motherboard but the hard disk, electric component from the damage while in another computer the system is the separate component. This topic has a brief description of the system unit so read it to the end to get complete information on the topic.

What is a system unit and describe its component?

A system unit is also described as a tower that can define a hardware case that protects the computer’s main component or primary devices i.e., power, RAM graphics card, CD-ROM drive, hard disk drive, internal cables, CPU which form the entire computer as a functioning computer. The basic reason for the system unit is to protect the computer components also act as the insulator which protects the computer damage from the electricity.

System unit physically in a box form which has all the components related to electricity. Some say it is the CPU, it is also called the computer chassis, cabinet, box, tower enclosure, housing, etc.

Components of the system unit

Some of the components of the system units which are inside it are discussed in the following section:

Motherboard:

The motherboard is also known as the system board or mainboard, in the microcomputer, the motherboard is the main component.it has a different connector where other components can connect in different ways.IT has the CPU BIOS, memory, mass storage interfaces, expansion slots, parallel and series ports, and the control of the devices such as the keyboard, mouse, disk drive, etc.

Hard drive:

The hard drive has the maximum capacity, low volatile and a magnetic storage device along the volume drive attached which is not removed in any case. The data stored on it is magnetically written and read on a platter with the help of the read and write heads which are over the platter as a cushion of air.

Floppy disk:

The floppy disk function is the same as the USB drive in the modern days. The function is to read and write the floppy disk which is absolute nowadays.

Power unit:

The currents which are attained through the different computers are converted from the AC currents from the main source to the DC voltage. The power supply gives the output in watts and the max power transfer by power unit is 350 watts. the power supply increase with the components of the operating system.

CD ROM drive:

It is a high-capacity storage device that is removable and it writes the data onto and read from the storage medium. The CD ROM is attached to the computer through IDE(ATA), SCSI, S-ATA, FIREWIRE, OR USB.
