Ultimate Laptop Buying Guide: All Laptop Features Explained


You’re sure to come across technical explanations of computer components while looking for laptops. It’s simpler to choose a good laptop or notebook computer that suits your computing habits if you understand what these technical factors mean for your laptop’s performance. Here are some facts on the most important laptop components you’ll come across.

Laptop Components:

Laptop Features Explained


The central processor unit (CPU) is the computer’s operating component. Computer processor speeds are measured in gigahertz (GHz). On the same chip, multi-core CPUs feature many processor cores. These processors’ speed ratings represent the speed of each individual core. The quicker the laptop processor is and the more cores it has, the more jobs it can handle at once.

Hard Drive

Your laptop’s memory is stored on the hard disk. A huge hard drive helps you to install and save more applications and files. Hard drives with hundreds of gigabytes of storage space are common in today’s high-performance laptop computers. Hard drives typically spin at 5,400 rpm, but you may receive a performance increase by upgrading to a 7,200 or even 10,000 rpm disk. You can also have several hard drives installed.

System Memory

One of the key components that will make your laptop operate quicker is random access memory (RAM). Your computer will be able to run more programs simultaneously and work with more extensive multimedia programs if you have a lot of RAM. A Web-browsing laptop should have around 2 GB of RAM, whereas an entertainment laptop should have 4 to 8 GB.


Laptop screens are made on thin liquid crystal displays (LCDs). Running your laptop display at native resolution, which is the resolution at which the image matches the exact number of pixels on the screen, produces the clearest image. The greater the native resolution of the laptop screen, the more detailed the picture will be. A touch screen is now standard on many new models.

Drive Optical

The optical drive on a laptop is a DVD or CD drive. A DVD+/-RW drive, often known as a burner, is included in most modern laptops and reads and writes blank DVDs and CDs in all formats. These are useful for backing up vital files and transferring home videos on a disc. Although some smaller laptops may not include an optical drive to conserve space and weight, the great majority of notebook PCs have. Consider the benefits of new laptops vs. used laptops.

External Ports

The number of external ports on a laptop differs from one to the next. At least two USB ports will be available for connecting a printer, smartphone, or camera. If you wish to connect to a different display or a projector, search for a VGA port. Memory card slots for MMC and SD cards may be available on your laptop computer.


An Ethernet port allows you to connect to a network via an Ethernet cable. In recent computers, wireless connections utilizing a wireless-G or wireless-N signal are almost universal. Many families are also setting up home wireless networks to use their laptops to access the web while sitting on the couch or at the breakfast table. In this guide on Wireless Routers vs. Wireless Connections, we compare networking alternatives.

Graphics Card

Laptop Graphics Card

Video cards, often known as graphics cards, are the components that allow your laptop to display graphics. A graphics controller is built into every laptop CPU, allowing the computer to display introductory video and graphics. On the other hand, a video card is a separate device that relieves the processor’s strain, allowing the laptop to operate smoothly and fast whether watching movies or editing photographs. Some video cards have their system memory, resulting in smoother, quicker performance.

Thunderbolt 3 / USB Type-C Ports

Laptop Type C Port

USB, the universal connector that charges your phone and tablet, writes data to your flash drive, and even links you to convenient docking stations, is beloved by everybody. Your old laptop undoubtedly has a few USB Type-A connectors, but many newer systems include USB Type-C ports, which open up a whole new world of possibilities. USB Type-C connections can transport both data and power over a single wire, allowing you to power your laptop, output video to external monitors, and copy files, all with a single standard cable. Even better, all USB Type-C cables are reversible, so you’ll never have to worry about plugging them in the wrong way.

Although not all laptops with USB Type-C support charging, those who do will be able to use a standardized ecosystem of AC adapters, docks, and displays. Because Type-C is an industry-standard, you can use the same power brick with multiple manufacturers of laptops, tablets, and phones. Finsix produces a USB Type-C version of the Dart, its incredibly small charger, while Innergie sells the PowerGear USB-C 45, which is somewhat larger but less costly.

Thunderbolt 3, which utilizes the same USB Type-C connection and is completely compatible with Type-C devices, but adds capability for even faster Thunderbolt peripherals, is available on some higher-end laptops. With Thunderbolt 3, you can connect to an external video card for gaming, power up to two 4K displays over a single cable, transfer data with a portable backup drive at the speed of an internal SSD, and power up to two 4K monitors over a single wire.

OLED Displays

Laptop OLED Displays

You could be forgiven for thinking your laptop’s display looks dreary and lifeless after looking at your smartphone. The finest phone screens on the market, such as the Samsung Galaxy Series and Google Pixels, use OLED displays that cover well over 100% of the sRGB color gamut, making images on the screen seem better than in real life.

The Alienware 13 and the ThinkPad X1 Yoga are the only laptops with OLED screens currently available. The bright hues of the 2016 models of both laptops wowed us. In 2017, we hoped to see even more OLED laptops introduced.

2-in-1 PCs

There’s nothing better than your laptop’s keyboard and touchpad for sending emails, surfing the web, or getting work done. However, you wish it were a tablet when you’re on a plane and want to watch a movie or in line at the shop and want to check Facebook. A new generation of 2-in-1 PCs provides you the best of both worlds: a laptop that can fold flat for productivity or a slate experience when the screen is detached. That’s something your three-to-five-year-old laptop can’t accomplish.

Wi-Fi 802.11ac

Most new laptops now come with 802.11ac Wi-Fi, a faster wireless standard that allows you to get three to ten times quicker rates than earlier wireless standards, especially as you get farther away from your network. You may need to upgrade your router to take full use of this protocol, but 802.11ac-capable access points start at less than $100. Because most smartphones launched in the previous two years support 802.11ac, your phone will benefit as well.

Infrared Camera for Windows Hello

You may now log into your Windows 10 machine simply by looking at it. A similar feature is Windows Hello. It requires either a laptop with an infrared or RealSense 3D camera built-in or an external webcam with these capabilities built-in, such as the Logitech Brio. When looking for a laptop, seek one that has one of these cameras, or that has Windows Hello facial recognition expressly listed as a feature. You can also use a fingerprint reader with Hello, but it’s not as amazing.

Laptop FAQ’s


What Is the Best Laptop Brand?

The laptop market used to be segmented by price, with low cost implying bad quality, but that has evolved. Manufacturers of low-cost gadgets enhanced their goods, while manufacturers of high-cost equipment reduced manufacturing costs. This is due to client requirements and technological advancements: new materials and manufacturing processes have developed, and electronic components have grown more powerful and less expensive (especially in mass production).

As a result, the price of a modern laptop is linked to its performance and quality rather than the brand name. Furthermore, businesses began to manufacture a range of laptops for various uses, including ordinary duties and document production, professional activities, business, and computer gaming. In some cases, the laptop configurations change, increasing the cost.

Companies that have been around for decades as well as others that are very new to the laptop computer market, in particular:

  • Asus
  • Dell
  • Lenovo
  • Hewlett-Packard (HP)
  • Acer
  • Sony
  • Samsung
  • Apple
  • Razer
  • MSI

Toshiba, Fujitsu, and Microsoft laptops have a limited market share, although the first two’s models are of good quality. Microsoft has only lately begun producing laptops and has struggled to achieve customer approval. Razer specializes in gaming computers.

What Is the Standard Size Of Laptop?

The diagonal of the screen, measured from one corner to the opposite, is the most important characteristic. There are versions ranging in size from 10.1 to 20 inches on the market. Because the casing thickness and display aspect ratio vary, the linear dimensions of devices with the same diagonal differ.

Netbooks are portable computers with displays ranging from 10.1 to 13.3 inches. Ultrabooks are small, light, and powerful, with screen sizes ranging from 12 to 13.3 inches. Universal laptops have screens ranging from 13.3 to 15.6 inches, and machines with a diagonal of 15.6 to 17.3 inches or more can take the role of traditional desktop PCs.

How Much Does A Laptop Weigh?

Compact laptops with tiny displays are the lightest (1-1.2 kg). The weight of a medium model (14-15.6 inches) is 2.3-2.5 kg, while a 17.3-inch model is 2.6-3 kg. Even with the same screen size, ultra-thin devices are lighter than traditional tablets. However, in addition to the weight of the laptop, you must consider the weight of the charger, which is around 400 g, though there are versions with smaller power adapters available.

How Long Should A Laptop Run On Battery?

A laptop is a computer that can function alone. Lithium-ion batteries are utilized as backup batteries because they can endure much charging and draining cycles. The battery capacity stands out among the key parameters. Its size determines a laptop’s power consumption.

For example, 15.6-inch laptops use 4400 mAh batteries that last about 2-3 hours on average. Portable versions and small ultrabooks may function for up to 4-6 hours without a network connection, whereas netbooks with their modest performance can last up to 8 or even 10 hours.

Portable versions and small ultrabooks may function for up to 4-6 hours without a network connection, whereas netbooks with their modest performance can last up to 8 or even 10 hours. The running time is affected by the load: resource-intensive apps (movies, games, graphics, and video editors) will drain the battery faster, whereas office programs will not. A second power supply may be added to some versions to increase the battery life.

What Is A Laptop TV Tuner Card?

This component enables you to view digital television on your laptop directly. Tuners are both built-in (placed within the laptop casing) and external (positioned outside the laptop case) (connected to one of the side connectors).

A good choice for TV fans who don’t want to buy more televisions. The quality of playback is influenced by the amount of signal reception and the laptop’s performance: on low-performance laptops, the image may diverge from the sound. Furthermore, during the decoding of the video stream, the laptop gets drained quicker.

Materials Used For Laptop Casing

Plastic is the most frequent material used to make casings. Cheap computers are more brittle, and their surfaces wipe faster due to the touch with hands, whereas more costly ones employ high-impact plastic.

Some versions can endure fall from many tens of centimeters and are resistant to rain, sand, and extreme room temperatures. This is accomplished by using high-quality materials, the reduction of gaps between sections, and the installation of port protection.

Rubber pads are put on the corners and sides of various rulers (for example, on small laptops for schoolchildren). Rubberized inserts can be seen on the bottom of the gadgets: they are required to keep the laptop from slipping off the smooth surface. Rubber is also used for the legs.

The bodies of high-end versions are constructed partly or entirely of metal: anodized aluminum that has been polished and covered with weather-resistant paint. These laptops and ultrabooks are far more sturdy, robust, and long-lasting than those with plastic coverings. Metal and plastic are combined in cheaper computers.

What Colors Do Laptops Come In?

The most common colors for sale are black, silver-gray, white, and red, but particular lines stand out and grab attention with vivid hues such as blue, pink, gold, and others, as well as unique color combinations. Laptops designed for kids and ladies typically have multicolored casings. Models in the business class have a rigid design and come in metallic gray, gold, black, and dark red. Gaming laptops are often gray or black with contrasting colorful stripes.

The case’s surface might be smooth or rough, with or without a design. The laptop does not slip out of the hands in this case, and the textured surface of the touchpad offers greater contact with the fingertips, making working without a mouse simpler.

Which Operating System Is Used In Laptop?

A shopper who does not want to spend a lot of time setting up a new laptop might choose a computer with a pre-installed Windows operating system, such as Windows 8 or 10, in a home or professional version.

Mac OS X is usually installed on Apple computers. You may instantly begin working with Chrome OS, Android, or another Linux-based operating system that comes preloaded.

Because reasonable consumers are unlikely to overpay for software they won’t use, vendors provide a selection of laptops with non-graphical operating systems (MS-DOS or FreeDOS).

There are models without an operating system at every retailer. These choices are appropriate for sophisticated users or those who want free, open-source software.

Laptops have evolved from a high-priced, niche technology to commonplace gadgets that are easy to use and don’t take up much space. Customers are increasingly opting for laptops over large desktop PCs.

Mobile devices that fit in a backpack or luggage are preferred by students, teachers, tourists, businesspeople, and IT employees. Compact technology is becoming more popular as the cost of electronic components decreases and manufacturers adhere to fair pricing policies.
