Virtual Laptop
Basically there are so many similarities on the components in the computer and in the laptop. The differences are the size of the components, in laptop, the components are much smaller in size (dimension) and the weight of the components are much lighter than the ones in the computer. Here are the types of components on a laptop;
The first one was power supply, this hardware has so many functions, one of them is to convert the electricity current from the AC to DC, so that the CPU can supply the electricity energy to operate all of the components in the computer including the hardwares. Next is about the motherboard, The motherboard is a printed circuit board (PCB) that contains and controls the components that are responsible for processing data.
The motherboard contains the CPU, memory, and basic controllers for the system. The motherboard has a Real-time clock (RTC), ROM BIOS, CMOS RAM, RAM sockets, bus slots for attaching devices to CPU sockets, cache RAM slots, jumpers, keyboard controller, interrupts, internal connectors, and external connectors.
VGA card is one of the hardware that work as the output source for the monitor, speakers or interact with the network. While the hard disk drive is a permanent storage area for data and the programs used to create the data. There are two types of hard disk that can be set onto the computer. They are the internal and the external hard disks. The difference is that the external is set outside the computer that is connected by a USB cable. The internal hard disk is set inside the CPU, connected to all the other hardwares inside the computer.
The optical driver has so many types, the types are based on the format of the discs that the driver work on. The optical drive can work as a disc burner or disc player. Many new types of optical drives are being invented, one of the most recent was the blue-ray driver.
RAM is a hardware that can make the computer work faster if the specification of the RAM is good. The better specifications that the RAM has, the faster of the computer’s operation can be done. There is a value of the memory in a RAM that is basically used as the guide tio pick up which specification that is better.
LAN stands for Local Area Network, this facility can connect from one computer to another computer in a small range. This facility is supported by a special cable to be connected from one to the other computers.
The importance of learning hardware on a computer is that we can fix problems in our hardware by ourselves, besides that we can understand more about the mechanism of hardware in a computer. Therefore, we can learn about the basic technology in a computer from time to time.
