The computer’s main circuit board. It holds the CPU, RAM modules, and most of the circuitry. All adapter cards plug into it. It defines how much RAM, adapter cards, and the type of CPU the computer is going to have.
A program which processes data in batches
It sends the visual output that a program produces to the monitor, which displays it on the screen. For gamers and others who use very high end graphics or special video work regularly, the it is the most expensive part of the computer. These cards also run very hot and most have a fan on the side.
It holds “short term” information for the processor to use. This may be a program or a set of data. The processor is able to retrieve information from it at very high speeds. When the processor needs information that is not in it, it has to read the information from the hard drive, which is much slower.
It is the brain of the computer and the most important chip in the computer. When a program is run, it performs the calculations and carries out the commands.
The monitor works with a ... located inside the computer case, to display images and text on the screen.
Any part of your computer that has a physical structure, such as the keyboard or mouse. It also includes all of the computer's internal parts, which you can see in the image below.
Any set of instructions that tells the hardware what to do and how to do it. Examples of software include web browsers, games, and word processors. Below, you can see an image of Microsoft PowerPoint, which is used to create presentations.
This port looks a lot like the modem or telephone port, but it is slightly wider. You can use this port for networking and connecting to the Internet.
This port is less common on today's computers. It was frequently used to connect peripherals like digital cameras, but it has been replaced by USB and other types of ports.
These empty slots are where expansion cards are added to computers. For example, if your computer did not come with a video card, you could purchase one and install it here.

A computer that serves up information to other computers on a network. For example, whenever you use the Internet, you're looking at something that's stored on a server. Many businesses also use local file ... to store and share files internally.
Handheld computers that are even more portable than laptops. Instead of a keyboard and mouse, they use a touch-sensitive screen for typing and navigation.
The computer case is the metal and plastic box that contains the main components of the computer, including the motherboard, central processing unit (CPU), and power supply. The front of the case usually has an ... and one or more optical drives.

This is where you'll connect the power cord to the computer.
Almost every computer has two or more audio ports where you can connect various devices, including speakers, microphones, and headsets.
RAM is your system's short-term memory. Whenever your computer performs calculations, it temporarily stores the data in the RAM until it is needed.This short-term memory disappears when the computer is turned off. If you're working on a document, spreadsheet, or other type of file, you'll need to save it to avoid losing it. When you save a file, the data is written to the hard drive, which acts as long-term storage.
RAM is measured in ______________ and _______________. The more RAM you have, the more things your computer can do at the same time. If you don't have enough RAM, you may notice that your computer is sluggish when you have several programs open. Because of this, many people add extra RAM to their computers to improve performance.
The hard drive is where your software, documents, and other files are stored. The hard drive is long-term storage, which means the data is still saved even if you turn the computer off or unplug it.
When you run a program or open a file, the computer copies some of the data from the hard drive onto the RAM. When you save a file, the data is copied back to the hard drive. The faster the hard drive, the faster your computer can _________________________.
The sound card—also called an audio card—is responsible for what you hear in the speakers or headphones. Most motherboards have integrated sound, but you can upgrade to a dedicated sound card for __________________________.
How is a laptop different from a desktop?
Because laptops are designed for portability, there are some important differences between them and desktop computers. A laptop has an all-in-one design, with a built-in monitor, keyboard, touchpad (which replaces the mouse), and speakers. This means it is fully functional, even when no peripherals are connected. A laptop is also quicker to set up, and there are fewer cables to get in the way.
You'll also have to the option to connect a regular mouse, larger monitor, and other peripherals. This basically turns your laptop into a desktop computer, with one main difference: You can easily disconnect the peripherals and take the laptop with you wherever you go.
Choose five main differences you can expect with a laptop.
It is the most important software that runs on a computer. It manages the computer's memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's language. Without it, a computer is useless.
You may have heard people talking about using a program, an application, or an app. But what exactly does that mean? Simply put, an app is a type of software that allows you to perform specific tasks. Applications for desktop or laptop computers are sometimes called desktop applications, while those for mobile devices are called mobile apps.
When you open an application, it runs inside the ...
A web browser is the tool you use to access the Internet. Most computers come with a web browser pre-installed, but you can also download a different one if you prefer. Examples of browsers include
