In fact, the human brain itself is a sophisticated computer, and scientists are learning more about how it works with each passing year.
Our most common use of the word computer, though, is to describe an electronic device containing a microprocessor. A microprocessor is a small electronic device that can carry out complex calculations in the blink of an eye. You can find microprocessors in many devices you use each day, such as cars, refrigerators and televisions. The most recognized device with a microprocessor is how computers work 10th edition pdf download personal computer, or PC.
In fact, the concept of a computer has become nearly synonymous with the term PC. When you hear PC, you probably envision an enclosed device with an attached video screen, keyboard and some type of a pointing device, like a how computers work 10th edition pdf download or touchpad.
You might also envision different forms of PCs, such as desktop computers, towers and laptops. The term PC has been associated with certain brands, such as Intel processors or Microsoft operating systems. Popular Electronics ran a story about the kit in its January issue, and to the surprise of just about everyone, the kits became an instant hit.
Thus, the era of the personal computer began [sources: Cerruzi, Lasar]. While the Altair was the first real personal computer, it was the release of the Apple II a couple of years later that signaled the start of the PC as a sought-after home appliance. The Apple II, from inventors Steve Jobs and Steve Wozniak, proved that there was a demand for computers in homes and schools. Soon after, long-established computer companies like IBM and Texas Instruments jumped into the PC market, and new brands like Commodore and Atari jumped into the game.
In this article, we'll look inside the PC to find out about its parts and what they do. We'll also check out the basic software used to boot and run a PC. Then, we'll cover mobile PCs and examine the future for PC technology.
Core PC Components To see how a PC works, let's start with the pieces that come together to make up the machine. The following are the components common to PCs in the order they're typically assembled: Case -- If you're using a laptop, the computer case includes keyboard and screen. For desktop PCs, the case is typically some type of box with lights, vents, and places for attaching cables.
The size of the case can vary from small tabletop units to tall towers. A larger case doesn't always imply a more powerful computer; it's what's inside that counts.
PC builders design or select a case based on the type of motherboard that should fit inside. Motherboard -- The primary circuit board inside your PC is its motherboard, how computers work 10th edition pdf download.
All components, inside and out, connect through the motherboard in some way. The other components listed on this how computers work 10th edition pdf download are removable and, thus, replaceable without replacing the motherboard. Several important components, though, are attached directly to the motherboard. These include the complementary metal-oxide semiconductor CMOSwhich stores some information, such as the system clock, when the computer is powered down, how computers work 10th edition pdf download.
Motherboards come in different sizes and standards, the most common as of this writing being ATX and MicroATX.
From there, motherboards vary by the type of removable components they're designed to handle internally and what ports are available for attaching external devices. Power supply -- Other than its CMOS, which is powered by a replaceable CMOS battery on the motherboard, every component in your PC relies on its power supply. The power supply connects to some type of power source, whether that's a battery in the case of mobile computers, or a power outlet in the case of desktop PCs.
In a desktop PC, you can see the power supply mounted inside the case with a power cable connection on the outside and a handful of attached cables inside. Some of these cables connect directly to the motherboard while others connect to other components like drives and fans. Central processing unit CPU -- The CPU, often just called the processor, is the component that contains the microprocessor. That microprocessor is the heart of all the PC's operations, and the performance of both hardware and software rely on the processor's performance.
Intel and AMD are the largest CPU manufacturers for PCs, how computers work 10th edition pdf download, though you'll find others on the market, too. The two common CPU architectures are bit and bit, and you'll find that certain software relies on this architecture distinction. Random-access memory RAM -- Even the fastest processor needs a buffer to store information while it's being processed.
Both a fast CPU and an ample amount of RAM are necessary for a speedy PC. Each PC has a maximum amount of RAM it can handle, and slots on the motherboard indicate the type of RAM the PC requires. Drives -- A drive is a device intended to store data when it's not in use. A hard drive or solid state drive stores a PC's operating system and software, how computers work 10th edition pdf download we'll look at more closely later.
This category also includes optical drives such as those used for reading and writing CD, DVD and Blu-ray media. A drive connects to the motherboard based on the type of drive controller technology it uses, including the older IDE standard and the newer SATA standard. Cooling devices -- The more your computer processes, the more heat it generates.
The CPU and other components can handle a certain amount of heat. However, if a PC isn't cooled properly, it can overheat, causing costly damage to its components and circuitry, how computers work 10th edition pdf download. Fans are the most common device used to cool a PC. In addition, the CPU is covered by a metallic block called a heat sink, which draws heat away from the CPU.
Some serious computer users, such as gamers, sometimes how computers work 10th edition pdf download more expensive heat management solutions, like a water-cooled system, designed to deal with more intense cooling demands. Cables -- All the components we've mentioned so far are connected by some combination of cables. These cables are designed to carry data, power or both. PCs should be constructed so that the cables fold neatly within the case and do not block air flow throughout it.
A PC is typically much more than these core components. Next, we'll look at the ports and peripherals that let you interact with the computer and how you can add even more components using expansion slots. Ports, Peripherals and How computers work 10th edition pdf download Slots The core components we've looked at so far make up a PC's central processing power.
A PC needs additional components, though, for interacting with human users and other computers. The following are the PC parts that make this happen: Graphics components -- While some motherboards have on-board graphics, others include what's called an expansion slot, where you can slide in a separate video card. In both cases, the video components in a PC process some of the complex graphics data going to the screen, taking some of the load off your CPU.
A motherboard accepts video cards based on a specific interface, such as the older AGP standard or one of the newer PCI standards. Ports -- The word port is often used to describe a place on the outside of your PC where you can plug in a cable, how computers work 10th edition pdf download.
Describe a port by its use, such as a USB port or an Ethernet port. Note that the word port is also used to describe a software connection when two pieces of hardware try to communicate. Many ports are affixed directly to the motherboard. This includes your basic input and output devices: monitors, keyboards and mice. It also includes printers, speakers, how computers work 10th edition pdf download, headphones, microphones, webcams and USB flash drives.
Anything you can plug in to a port on the PC is one of the PC's peripherals. The essential peripherals such as monitors aren't necessary on laptops, which have them built in instead. Expansion how computers work 10th edition pdf download -- On occasion, you'll want to add components to a PC that don't have a designated slot somewhere on the motherboard.
That's why the motherboard will include a series of expansion slots. The removable components designed to fit into expansion slots are called cards, probably because of their flat, card-like structure. Using expansion slots, you can add extra video cards, network cards, printer ports, TV receivers and many other custom additions. Now that we've looked at the parts of a PC, let's press the power button and see what makes it boot.
Powering Up a PC When you first power up a PC, the machine goes through several internal processes before it's ready for you to use. This is called the boot process, or booting the PC. Boot is short for bootstrap, a reference to the old adage, "Pull yourself up by the bootstraps," which means to start something from the very beginning.
The boot process is controlled by the PC's basic input-output system How computers work 10th edition pdf download. The BIOS is software stored on a flash memory chip. In a PC, the BIOS is embedded on the motherboard. Occasionally, a PC manufacturer will release an update for the BIOS, and you can carefully follow instructions to "flash the BIOS" with the updated software.
Besides controlling the boot process, the BIOS provides a basic configuration interface for the PC's hardware components.
