While many students still go on campus, there is no shortage of computers. Most colleges have at least one mega lab with nearly a hundred computers. But if you wish to bring your own laptop there are plenty of wireless hot spots where you could get a connection to the internet from anywhere on campus. Understandably lugging textbooks around campus may seem exhausting and tiring, you now have the option to get an electronic e-Book of most textbooks needed for class.

Portable computers are compact and fully functioning versions of a regular desktop computer that are designed to be mobile. While they rely on rechargeable batteries or an electrical outlet for power, they allow a person the freedom to move around while still being productive. Their mobility alongside their ability to operate similar to a desktop make them powerful tools for businessmen, students, and common individuals alike. Whether giving or preparing a project or presentation, taking notes or studying online, or simply connecting to the internet from a cafe, portable computers have become essential for individuals who wish to work, study, or play on the go. Portable computers come in three basic versions which include the laptop, tablet, and netbook.

Laptops are thin computers that contain a keyboard and monitor folded on top of each other so that the top half is the visual display and the bottom half is the input. Laptops are commonly called "notebooks" do to this folding feature and their thin appearance. Recently, touch screens have been introduced into some laptops allowing some operating systems like Windows 8 to open applications with the touch of a finger. While laptops are comparable to desktops in their use, their smaller size results in some small amounts of the computing power and functionality being lost. However, their compact size allows them to be stored when not in use and the familiar "nest" of wires associated with linking up a desktop is reduced to a single power cord. Laptops are also better at "creating" fully functional content when compared to a Tablet or Mobile Device (such as a cell phone). If you require the ability to write reports or long e-mails, to use a spreadsheet in order to crunch numbers, to create a "PowerPoint" presentation, to rearrange music libraries or photo albums, or to edit pictures then you will need a desktop, laptop or a netbook. Tablets and Mobile Devices are more designed to consume content than to create.[13]

Netbooks are similar to laptops but differ in size as well as processing. While netbooks are smaller versions of laptops, they have been designed, to the best of their ability, to have the same functionality as laptops and PCs. A netbook's computer display will rarely reach above 10" or 12", and are more commonly smaller than this, whereas some laptops can contain up to 15.5" of display screen. Netbooks have been around since 2008, roughly, and have revolved around their ability to connect to mobile networks such as the wifi at your local cafe or restaurant. Because of this feature, it has changed the laptop industry and has been heralded as a revolutionary and pivotal focal point in the production of laptops and netbooks. Since then this capability has now become a standard among both. Even though they don't maintain some of the functionality and computing power as their desktop and laptop counterparts, they are still capable of word processing, mathematical computation, and other productivity programs that businessmen and students use. On top of that, they are also extremely durable and affordable which make them perfect for educational tools. Students will find them easy to manage, organize, and carry around as well as a "distraction free" resource because of their minimalistic capabilities. Couple these advantages with internet access to mobile hotspots such as school libraries and it can be easily seen why this device had dominated the market for so long. It has only been a recent trend for individuals to pick up the tablet despite it's rudimentary processing power and it has been speculated that this is due to the tablet's sleek design and effective marketing strategy toward the younger generation.[15]

Examples of other pointing devices can be seen in gaming. A popular pointing device in video games is the joystick. Joysticks are moved by hand to point to an on-screen object, such as a character, and then a button or buttons are pressed to execute an action, for example jumping. Gamepads are also examples of pointing devices, performing similar functions to the joystick but held fully in hand instead. Another example of a pointing gaming device is a proprietary controller, such as the Wii remote. These devices are motion sensitive and require the controller to point into a sensor, which will move accordingly with an on-screen pointer. A trackball is a pointing device consisting of a ball in a socket, similar to an upside-down mouse, that the user rolls with the thumb, fingers, or palm. Trackballs are commonly seen on CAD workstations for ease of use. Control buttons and wheels are pointing devices commonly found on handheld gaming devices or portable digital media players. For instance, on an ipod, the user can spin the wheel to scroll through songs, and then click on the desired track. Touch pads are generally rectangular pads that a user can slide a thumb or fingertips across. Tapping the touchpad executes the same action clicking a mouse would. Touch pads are typically found on laptops and notebook computers. [11]

Biometrics are objective, measurable, biological traits that can be used to identify somebody.[25] Biometric identification is becoming more and more common, and individuals can be recognized by a computer based on everything from their eyes to their fingerprints, from their voice to their face, from their unique body odor to the shape of their ear. Some uses of biometrics include fingerprint scanners to protect sensitive information stored in databases at places like nuclear power plants, biometric identification at borders and on passports, identification at nightclubs to ensure people who have been banned can't enter, and even at public schools to have stronger records of attendance and library book borrowing.[26] While biometric authentication is incredibly useful, there can also, obviously, be strong privacy concerns if their use is becoming too common. However, an organization called the Biometrics Institute is seeking to not only advance the use of biometrics but also ensure that all privacy concerns are addressed as this kind of technology becomes more and more common, with a set list of privacy guidelines that should be met whenever and wherever biometric identification is being employed.

Chrome OS is an open-source operating system created by Google to create a better computing experience for people who spend most of their time on the web. [General referenced 1]On June 15, 2011, Chrome OS was launched to the public with the first Chromebooks, notebooks using the Chrome OS, created by Samsung and Acer. Today, Chromebooks are created by a number of other computer companies including HP, Toshiba, Asus, and Dell. The main reason the Chrome OS differs from other operating systems is that it allows for user data and applications to reside in the cloud, taking up less space on the computer hardware. By not storing files and data on the system it allows the Chromebooks to boot up faster. Which in return helps prevent viruses; making it an overall more secure and efficient laptop. Because of this, many Chromebooks only contain the same amount of memory and RAM as the average smartphone, Google, however, supplies each user with one-hundred gigabytes of Google Drive cloud storage for up to two years.

There are many types of application softwares. Every type of application software is made to serve a function or to help, for example software for business' or education. Desktop publishing refers to using a personal computer to manipulate text and images to create attractive documents as if they were created by a professional printer. Similar to this, personal publishing softwares are used to create documents for personal use, such as invitations, flyers, or calendars. Very common types of application software include education and entertainment. Entertainment software includes games, simulations, and other programs that provide amusement. Educational software can be found on personal computers, but a popular trend is to combine the hardware and software into a single product. For example, Leapfrog is well-known for their child look-alike laptops used for teaching.[47] Software such as OneNote and Notebook are examples of note taking software. These softwares are generally used by students and business people to take notes during lectures or meetings. Because of this, note taking software normally supports typed and handwritten input. Engineers and architects make use of design software such as CAD (computer-aided design). CAD plays an important role in the design of finished products and other fields such as art, advertising, or law. 041b061a72
