Computers

A computeris an electronic device. It manipulates information or data. It has the ability to store, retrieve, and processdata. People can use a computer to type documents, send email, play games, and browse the Web,edit or create spreadsheets, presentations, and evenvideos.

Two things all computers have in common: hardwareand software.

·Hardwareis 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.

·Softwareis any set of instructionsthat tells the hardware what to doand how to do it. Examples of software include web browsers, games, and word processors. People use Microsoft PowerPoint to create presentations.

Everything you do on your computer will rely on both hardware and software. For example, imagine, you are viewing the e-book in a web browser(software) and using your mouse(hardware) to click from page to page.

When most people hear the word computer, they think of a personal computersuch as a desktopor laptop. However, computers come in many shapes and sizes, and they perform many different functions in our daily lives. When you withdraw cash from an ATM, scan groceries at the store, or use a calculator, you're using a type of computer.

Many people use desktop computersat work, home, and school. Desktop computers are usually on our desks. Most of them have a few different parts, including the computer case, monitor, keyboard, and mouse.

Tablet computers (tablets)are handheld computers. These computers are even more portable than laptops. Instead of a keyboard and mouse, tablets use a touch-sensitive screenfor typing and navigation. The iPadis an example of a tablet.

A serveris a computer. This computer serves up information to other computers on a network. For example, whenever you use the Internet, you're looking at something that is stored on a server.

Many of today's electronics are basically specialized computers, though we don't always think of them that way. Here are a few common examples.

Many cell phones can do a lot of things computers can do, including browsing the Internet and playing games. They are often called smartphones.

Wearables. Wearable technology is a general term for a group of devices. These devices are worn throughout the day. They are often called wearablesfor short. Examples of wearables are fitness trackers and smartwatches.

A game consoleis a specialized type of computer. We use it for playing video gameson your TV.

Many TVs now include applications. These programslet you access various types of online content. For example, you can stream video from the Internet directly onto your TV.

·Personal computers come in two main styles: PCand Mac. Both are fully functional, but they have a different look and feel, and many people prefer one or the other.

·This type of computer began with the original IBM PCthat was introduced in 1981. Other companies began creating similar computers, which were called IBM PC Compatible(often shortened to PC). Today, this is the most common type of personal computer, and it typically includes the Microsoft Windowsoperating system.

·The Macintoshcomputer was introduced in 1984, and it was the first widely sold personal computer with a graphical user interface, or GUI(pronounced gooey). All Macs are made by one company (Apple), and they almost always use the Mac OS Xoperating system.

A laptop is also quicker to set up, and there are fewer cables to get in the way.

2) Here are the main differences you can expect with a laptop.

· Touchpad:A touchpad (trackpad)is a touch-sensitive pad. It lets you control the pointer by making a drawing motion with your finger.
