Q & A

How long does it take to assemble a computer?

It takes about 90 minutes to assemble a computer.

What is the function of the hard disk drive in a computer?

The hard disk drive saves information transmitted to it for a long time, and the reading head reads this information with extreme precision.

What are the two units that safeguard information in a computer besides the hard disk drive?

The two units that safeguard information are the removable 3.5-inch disc reader and the CD ROM reader, which allow for the reading and execution of programs recorded on compact discs.

What is the motherboard's role in a computer?

The motherboard is the spinal column of the computer, to which all other elements of the computer are connected.

How does the processor function within a computer system?

The processor is the brain of the system, interpreting, calculating, and executing the instructions given to it, with an operating speed that reaches the gigahertz level.

What is the purpose of the RAM memory in a computer?

The RAM memory stores short-term information but erases it when the current is turned off. It is more rapid than the memory of the hard disk or CD ROM.

What is the role of the video card in a computer?

The video card creates images in two and three dimensions. The video memory's capacity determines the clarity of the image displayed on the monitor.

How does a modem facilitate communication between two computers?

A modem allows two computers to communicate by producing a perfectly clean phone signal through its capacitors, and its chip connectors control the information circulating between the two computers.

What is the significance of the printed circuit board in a computer?

A printed circuit board is a computer component that can produce spectacularly realistic scenes and is essential for the functioning of electronic devices.

How are the components of a printed circuit board assembled?

Components are assembled using two technologies: surface wiring and wiring through the card. They are placed into holes, soldered in place, and then the card is subjected to a convection oven for soldering.

What is the primary function of a robotic arm in a manufacturing setting?

A robotic arm is designed for repetitive work that is difficult, dangerous, or boring for humans, providing constant productivity without the need for breaks or time off.
