Electronics and Computers

Had someone told you a decade or so ago that you could video conference with your friends through your smartphone; you would have probably scoffed at him. However, thanks to the rapid development of electronics, especially at the nano level, it is now possible to perform that task. Had you used computers during the early 80s, the device would have contained 8 inch floppy drives and a 10 GB hard disk drive running on DOS (disk operating system). Nowadays, even the cheapest mobiles have memories in multiples of gigabytes. Computers, smartphones, and other electronic devices have changed the way we perform our day to day work.

The components of a PC

Modern generation computers contain electronic parts such as the motherboard, RAM (random access memory) ROM (read only memory), HDD (hard disk drives), the CPU (central processing unit), a DVD reader/ writer and a display unit. All of its parts, apart from the display unit are neatly arranged within a cabinet containing one fan to cool the CPU and another that works as an exhaust to suck in air from outside and circulating it inside to keep the electronic components cool. Most of them are sufficient for standard office tasks such as sending and receiving emails, composing text, generating Excel spreadsheets, and creating PowerPoint presentations. However, they do not have the power to play graphic oriented games that require higher processing power, a GPU (graphics processing unit) with its dedicated memory, plenty of powerful DDR4 SDRAM (double data rate, synchronous RAM), and a SSD (solid state drive).

The Laptop

While the desktop is good for use in office and homes, the laptop is ideal for people who want to work on their computers while on the move). These portable units pack enough power to perform most jobs, yet are light enough for you to carry comfortably while traversing from one location to the other.

The Internet

You depend a lot on the internet to send and receive mails, browsing the net, and for many other purposes such as VoIP (voice over the internet protocol). You need to hire the services of an internet service provider (ISP) to connect to the internet. Most of them supply internet connection from their hubs to your laptops and computers via a CAT cable, connected to your computer via a modem (modulator demodulator), which connects your PC and laptop physically through an Ethernet port or your smartphone and other devices, including your PC and laptop via WiFi (wireless fidelity). The speed of the connection is calculated in either mbps (megabits per second) or mbps (mega bytes per second). The aster the speed the faster you can download files or browse the internet.

Other electronic devices we cannot do without

Electronics plays a huge role in devices such as the TV, heaters, fridges, and air conditioners. Even devices in the kitchen such as blenders, toasters, and microwave ovens contain electronic parts. To put it across in simple terms, we simply cannot avoid computers and electronic goods, as they help us to perform our daily tasks effortlessly and quickly.
