What is a Laptop computer?
A laptop computer is a small and a portable computer. Today’s laptops deliver performance is what that’s on par with that of many desktops. Increased battery life is essential, more lightweight materials and compact components help allow for more performance and portability than ever before. The result is greater productivity for business users and more multimedia fun in more places for those that are of home user.
Dell has a laptop to fit the needs of most businesses, travelers, students and others who simply want the freedom to use a compact computer virtually wherever they like to. Dell laptop computers do come with a long list of optional features that makes life better. A built-in Wi-Fi technology has helped simplify connection to wireless networks. Mobile broadband has helped speed up the mobile online experience of users and Bluetooth connectivity has helped simplify use of wireless devices in conjunction with a laptop computers.
When purchasing a DellTM laptop, consider how you plan to use it then find one that meets the precise size and weight for your portability needs. When you purchase a Dell InspironTM laptop, you even have the freedom to choose an optional color or design that fits your personality affinity.
Types of laptop computers
All Laptop computers come in a variety of weights and sizes and sizes. The basic classifications are:
Ultraportable laptop computers typically weigh the least, are very small and very extremely slim. Typically, less than three pounds most times, most come with a display size of 12 inches or less. While easy to carry, ultraportables may offer relatively low system performance and a small sized keyboard and display as well.
Thin-and-light laptop computers mix portability with performance and other features. They typically weigh four to five pounds with a display size of 12 to 14 inches mostly. Thin-and-light laptops often feature a mid- to full-size keyboard, especially for comfortable typing, but may or may not include built-in optical drives.
Mainstream laptop computers are slightly larger and heavier than thin-and-lights with 14- or 15-inch displays screens. Generally, the mainstream laptop will provide performance and features that are equal to those of a thin-and-light laptop, but with more peripheral connections and a slightly lower price.
Desktop-replacement laptops are the heaviest and largest family of laptop computers. They can be more difficult to carry around, but with display sizes of approximately 17 inches, they provide the most on-screen workspace and typically more hard drive space than mainstream laptops does.
Laptop uses – for business or for pleasure?
Laptops are purchased for personal use, business use, or both combined. Those seeking a personal laptop usually consider the entertainment desires it can fulfill for them. Business users, on the other hand, are typically more concerned with productivity and data security more.
While processor speed and data-storage capacity are important considerations in both instances, business users may want user-authentication features like a biometric fingerprint reader or smart-card support to help protect sensitive business data they may have. Business users may also require multiple wireless connectivity options so that they can connect to networks in a broad range of the work environment.
Personal users, however, might want to purchase a laptop that will play their favorite movies and music while storing photos as well. Ever-faster processors, high-definition displays and enhanced sound capabilities combine to make the laptop a complete mobile multimedia entertainment platform. A range of optical drives, including those with Blu-ray compatibility, helps ensure that whether you are into music, movies or games, Dell laptops have you covered.
Benefits of a laptop computer
The most obvious advantage and benefit of the laptop computer is its mobility. In addition, as processor manufacturers pack more performance into their products, they are learning to manufacture processors that also require less energy to operate and produces very lesser heat. Coupled with technology that has allowed lighter, longer-lasting and more compact batteries, DellTM laptops offer a world of performance while occupying a very small space in your world.
Anatomy of a Laptop Computer
Display and the display size
The display on your laptop is the first window into your digital world. In recent years, Active matrix (or TFT, thin film transistor) displays have become a popular display technology because of their bright, vivid images that can be viewed from wide range angles. Moving up a step, high-resolution, high-definition displays can give your movies and photos more life-like images with crisper and clearer details. Yea, The higher the resolution, the more information can be displayed and the sharper the definition and color.
When choosing a laptop, remember that the larger its display, the easier it can be to work with and view movies on if you love movies. But at the same time, larger displays can reduce your level of mobility.
The Central Processing Unit (CPU) of a computer is the brain of your computer and the largest single determinant of system performance. A laptop CPU will often differ from a desktop CPU in that it’s engineered with advanced power management features that are used to help extend battery life. Most laptops today offer multiple-core processors, allowing parallel processing of multiple tasks for fast performance. Multiple-core processors currently range from two to four processor cores per chip.
Random-access memory (RAM, or just “memory”) is utilized by the processor to open, close and manage tasks across multiple applications. The more memory a computer has, the faster the performance of your laptop. Most laptops now come with 1GB of memory, though 2GB is often recommended. Most laptops have capacity for 4GB up to 8GB or even 16GB of memory.
Hard drive (or HDD, Hard Disk Drive)
The hard drive of a computer is where all the data on your laptop is stored, including the operating system, applications and user data. Hard drives employ different rotational speeds, measured in RPM, which directly affect performance. Generally speaking, higher RPM equal faster performance for a laptop.
Hard drive storage capacity is typically measured in gigabytes (GB) with sizes now exceeding 300GB to as much terabytes as possible now. If you store lots of music, video and photos, you should consider a laptop with at least 250GB of storage.
Optical drive Almost all laptop computers feature internal optical drives now. Most users want re-writeable DVD and CD drives, which enable easy creation of CDs and DVDs containing music, video or backups of files. Laptops with high-definition displays can also benefit from the latest optical technology: Blu-ray. This technology was developed majorly to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data.
Dell laptops are designed to keep you connected to the Web in a variety of ways. Dell’s Wi-Fi catcher helps you find the strongest wireless signal and connects you to it. Our exclusive Hyperband Multi-Antenna utilizes three antennas deigned to find and connect to networks with ease. And to keep you moving quickly, available next-generation Wireless-N technology provides fast data transfer rates.
A video card is a separate, dedicated expansion card that is plugged into a slot on the laptop’s motherboard. Video cards are designed to provide increased video performance over the standard integrated graphics processor (IGP) found in most laptop computers. Video cards are sometimes required for operating high-end graphics applications or running multiple monitors off one laptop. In most cases, IGP is sufficient.
USB 2.0 or 3.0 Ports
USB 2.0 ports allow you to connect to peripheral devices such as digital cameras, scanners, and printers. Originally, USB was intended to replace the multitude of connectors at the back of PCs, as well as to simplify software configuration of communication devices. Most peripheral hardware now connects to a laptop via USB 2.0 or 3.0 ports, so consider whether you’ll use an external mouse, keyboard, printer or other devices and select a laptop with a sufficient number of ports.
