what are the internal and external components of laptop

Laptop Components 

Every person who wants a laptop computer must have thought carefully about the technical specifications of the computer components, because those specifications are what determine the level of computational efficiency, and the following are the most important components of the laptop: 


The central processing unit is the component responsible for the device, whose speed is measured in gigahertz, and there are multi-core central processing units made up of internal processing units in the same chip, and the higher the speed of the processing unit, turn, will be reflected in the speed of the laptop.

Hard Disk 

A hard drive is a laptop’s memory storage unit, which the larger the space it allows to install more large programs and save more files. Today’s high-performance laptops have hard drives with hundreds of gigabytes of storage space, and typical hard drives operate at 5,400 speeds. RPM, but better performance can be obtained with a 7,200 or even 10,000 RPM hard drive.

system memory

Random access memory (RAM) is one of the main components that make a laptop run faster, a lot of RAM will allow a laptop to run more programs simultaneously, in addition to working with large multimedia programs, a laptop that is browsing the Internet needs to About 2 GB of RAM, while a laptop dedicated to entertainment can range between 4 and 8 GB.

the screen

Laptops use liquid crystal display (LCD) displays, and the clearest picture that plays on the laptop screen can be obtained with the original resolution, which is the resolution at which the image matches the exact number of pixels on the screen and the higher the resolution of the original screen of the laptop the better the image quality more details.

optical drive

A laptop optical drive is a DVD or CD drive, and most new laptops come with a DVD +/- RW drive, also called a burner that reads and writes DVDs and blank CDs in all formats. Importance of this feature is for backing up important files in addition to putting home videos on a disc, and some small laptops save space and weight by not having an optical drive.

External Ports 

The number of external ports varies from one laptop to another so that each one has at least two USB ports, we may also find a (VGA) port for connection to a separate monitor or monitor, and the laptop may also include memory card slots for MMC cards. and (SD).


An (Ethernet) port connects via an (Ethernet) cable to a wireless network using a Wireless – G or Wireless- N signal, and is available in almost all new laptops, and many families are now creatingwirelesshome networks, so they can use their laptops to Browse the web from anywhere in the house. 

Typical laptop components

Touchpad: It is a panel with a very high sensitivity that is used to control the cursor by drawing a finger on it, and it also has another name, the trackpad.


All laptops include batteries, where the computer is used without the need to connect it to the mains, and when the laptop is connected to electricity, it charges the battery, which provides additional power in the absence of an electrical outlet.

AC adapter: 

A laptop computer has a dedicated power cord called an AC adapter, which is created to be used with this type of laptop.


Most laptops have the same types of ports as desktop computers, such as (USB), but sometimes they have fewer ports to make room for an adapter that we may need to use.

Memory and logic unit.


CD drives.

Computer multimedia devices (modems), where you insert an audio reproduction adapter and amplifiers.

Laptop Features :

energy conservation.

Produce less heat than desktop components.

It can be moved easily.

Which is a better laptop or a tablet?

Because of the tremendous advantages offered by tablets, some users rely on them as an alternative to laptops, but can those who depend on the work on the laptop move to the tablet? What is the best option for those who wish to acquire one of the two devices? Answering the two questions requires shedding light on some of the differences between a tablet and a laptop, including the following:

Input method: 

If you are a user whose work nature requires using the keyboard continuously, for example, as writing emails, writing articles, or other tasks, then the laptop is the right choice because the tablet computer depends mainly on the touch screen and the default keyboard does not allow the user to type at high speed and accuracy, compared to the practical keyboard in a mobile device. Of course, tablet users can rely on an external Bluetooth keyboard, but this leads to an increase in the price and the need to attract it every time as a peripheral device.

Battery life: 

Because of the differences in the internal components between the laptop and the tablet, the balance will tilt strongly towards the tablet in terms of battery life, as the tablet battery can simply last up to ten hours when using the Internet, while the A mobile battery usually lasts up to four hours, with the presence of There are some exceptions, so a tablet is preferred over a laptop in case of long daily use.

Storage capacity: 

The laptop on the tablet clearly succeeds in terms of storage and storage options, as it is considered the most tablet computer in the market, with internal storage space ranging between 16 and 128 GB, but the average storage capacity within laptops is five hundred GB. It also provides a laptop computer, as it is more flexible and smooth to add external memory disks of all sizes and types, while we will find that in a tablet computer the matter is limited to inserting a microSD card, an option that is not present in all of these computers. Therefore, a laptop computer would be the most appropriate and appropriate option if you want to save and store huge and huge amounts of data.
