A laptop has the same components as a desktop computer but in a portable unit. It includes a display screen, keyboard, trackpad replacing the mouse and a battery.
The best laptop for you depends on your needs and budget. Avoid laptops with low-end specs that will shorten their useful life.
Definition
A laptop, also known as a notebook computer, is a battery- or AC-powered personal computer that’s small enough to fit in your backpack or briefcase. It has a built-in LCD screen, keyboard and touch pad. Its case folds back like a book to keep the keyboard and display safe when you’re not using it.
Its rechargable battery lets you use it away from power outlets, making it useful in temporary spaces like on airplanes, at meetings or in libraries. It has ports that let you connect input/output devices such as a mouse and printer.
Most laptops have a hard disk drive for storage, but solid-state drives are starting to replace them in many models. These drives are faster and more energy-efficient, and they’re less likely to corrupt data from physical impacts.
Many laptops have a built-in Wi-Fi network and cellular connectivity so that you can surf the web without tethering to your phone or tablet. This makes it easy to work on projects at home, at school or in the office. Prolonged usage of a laptop’s integrated screen can cause neck or spinal injuries, so some health standards require ergonomic keyboards in workplaces.
Functions
The laptop, also known as a notebook computer, combines all of the functionality of a desktop PC in a mobile device that’s easy to carry around. Its functions include a display, keyboard, touchpad and battery. Its software allows users to manage documents, emails and video chats. The keyboard is a popular feature that provides a familiar QWERTY layout with function keys to perform specific tasks.
The touchpad, or trackpad, is a built-in pointing device that replaces the traditional mouse. The pad uses tactile sensors to translate movement and position of the user’s fingers on a specialized surface into cursor movement on the operating system’s screen. It is a key component for navigating the laptop’s interface.
The internal hard drive in a laptop stores files, applications, and operating systems. It can be either hot-swappable or cold-swappable, allowing the laptop to remain on while its hard disk drive is changed. The laptop’s speaker provides audio output for entertainment and communication. Hinges connect it to the laptop base panel and screen. It also protects electronic components inside the laptop from external dust or moisture.
Design
A laptop is a mobile computer that packs all desktop computer input/output capabilities in a portable form factor. It can run on AC power or rechargeable batteries and fold shut for storage and transport.
A typical laptop includes a keyboard, a mouse, data storage, a disc drive, and a processor with built-in memory. It also supports a variety of wireless networking technologies for connectivity with other devices and accessories.
A laptop’s hardware can be upgraded to improve its performance. Fast storage and a high-resolution display are especially important for graphic designers.
Graphics RAM is usually separate from system memory for efficiency, although some laptops, such as Apple’s M series SoCs, use a unified pool of system memory to improve performance. A high-end laptop may offer up to 16 GB of RAM, while budget models tend to have 8 GB. External hard drives, NAS data storage servers, or USB flash drives can supplement a laptop’s storage. The latest connectivity methods, such as Thunderbolt 4, are a bonus, and it’s also good to have HDMI and audio jacks.
Portability
Laptops are mobile computers that integrate all the components of a PC into a single unit and are powered by a rechargeable battery. This allows users to be productive at any location, such as on the train during a work commute or in the café during a break between lectures. Using a single device also ensures files are always up-to-date as opposed to multiple desktop PCs where documents can become out of sync with one another.
American computer scientist Alan Kay designed the first laptop prototype in 1968. His machine called the Dynabook, had a clamshell form factor, a flat-panel display on the inside of the upper lid, an alphanumeric keyboard, and a trackpad replacing the mouse.
Technology advancements in the 1990s further increased laptop utility and popularity. Improvements included lighter, more efficient batteries, active matrix displays that replaced inferior cathode ray tube (CRT) screens, more powerful Intel processors, internal modems, and more storage space. Manufacturers in the past used various marketing terms to differentiate laptops of different sizes, including netbooks, subnotebooks, ultra-mobile PCs, and desktop replacement laptops.
Security
Laptops can be a security risk if they don’t have appropriate protections. A lost or stolen laptop can be a magnet for identity thieves who can steal confidential information, proprietary business data, and more. For this reason, many SMBs implement a comprehensive laptop security policy to ensure that employees don’t put their company at risk by exposing sensitive data.
To protect against unauthorized access, it’s essential to have an effective system password and a secure operating system. A good password should be long, and incorporate a mix of upper and lowercase letters, numbers and special characters (e.g.,!, #, $). It should also be changed frequently to reduce the likelihood of a hacker guessing it by running a dictionary or other brute force attacks.
It’s also important to back up the device regularly and establish a specific time to do so. This will help protect against accidental deletion and hardware failures that can cause irreparable damage to a company’s valuable data. It’s also a best practice to avoid using public Wi-Fi, as hackers can use it to spread malware or position themselves between users and the internet to obtain private information.
