The computer system starts with its motherboard, which contains all the components of a computer such as its internal memory, processing unit (processor), hard drive, random access memory (RAM), and video output. In a laptop, the computer has additional components, such as the optical drive, sound card, wireless card, Ethernet card, hard disk, and others. All components of a computer are interconnected with one another and are powered by electricity supplied by the power utility.
The motherboards function to connect all components of a computer together through the use of PCI, AGP, IDE, USB, or parallel port devices. The physical configurations of a computer hardware are determined at the time when it is purchased. As a result, the motherboards that are similar in features will usually have the same hardware layout. There are however differences in the physical configurations of the motherboards that could cause some problems with your computer if it has not been correctly configured.
There are three main parts that make up the motherboard: the analog circuitry, the microprocessor, and the communication circuitry. The analog circuitry part is called the CPU (or central processing unit), which includes the ROM, PROM, and MSU. The CPU performs all arithmetic, logic, and memory operations. The microprocessor is embedded inside the CPU and is responsible for all components of a computer to execute instructions. Lastly, the communication circuit board connects all components of a computer together using I/O ports. It is generally made from a plastic like material and includes a pair of physical I/O ports, an LED, a reset switch, a 4-wire shield, and a connector for connecting the computer to the monitor.
If you want your computer to have more than just a regular computer hardware, then you need a video card. The video card is what draws the graphics and images to your monitor. There are two types of video cards: analog and digital. The analog card uses a CPU and a ROM to do all the work of processing graphics, while the digital card operates almost in the same way as a computer within your computer, but it does not need a CPU or ROM to do so.
Another type of computer components is the RAM. RAM is also known by the name of RAM, or random access memory. It is extremely useful to have because it makes your computer system able to run faster. There are two forms of RAM, namely primary memory and secondary memory, which are sort of like an upgrade of the primary memory that is inside the computer system.
Other components of a computer system include the USB, SD, DVD, and blu-ray disk drives. The USB consists of a U USB port and A B USB port. The USB ports can connect to various external devices like printers, scanners, cameras, digital cameras, as well as other peripherals like game consoles.
The SD or small digital camera is one of the latest additions to computer components. They provide you with picture resolution of up to six megapixels. This is way better than the regular cameras. Another component of a computer monitor is the HDTV. A HDTV basically offers high definition television viewing. It incorporates special features like a digital television tuner and a digital video recorder, which allow you to record any show or movie you want at absolutely any point in time.
All the components mentioned above are available in different configurations. The price range of these products may vary from very cheap to thousands of dollars. Different computers need different configuration of the hardware and software to function properly. You can find the complete specifications of all the hardware and software components of a computer through the manufacturer’s website.
