Home network: Ethernet or Wi-Fi

If you do not go into the jungle of network technology and do not utter such terrible words as a router, a switch, a hub and a routing table, the task boils down to the following: connect two computers in the same house. You can do this either by extending the network cable from one computer to another (99% of computers and laptops are equipped with an RJ-45 port), or by installing Wi-Fi adapters on computers (most laptops and netbooks have a built-in Wi-Fi adapter). Let’s look at the advantages and disadvantages of each method.
Price. The option with a network cable seems cheaper – you have to spend only on a cable, network adapters are already installed. But laying the cable around the house (especially if you have to drill holes in Continue reading

How to improve the noise characteristics of the system unit of a personal computer

When using a home personal computer to watch movies, listen to music or browse the Internet, especially at night, the noise of the system unit becomes especially noticeable. Permanent noise sources are active elements of cooling systems (ventilation) and hard disk drives.
Usually, several fans are installed in the system unit: on the processor heatsink, on the video card (if there is an active cooling system), for blowing the hard drive, for housing ventilation, in the power supply.

The most energy-intensive components of a personal computer are the central processor and video card. Accordingly, they have the most powerful cooling systems, which are the main sources of noise. On the other hand, since all modern processors, including graphic ones, are equipped with energy-saving functions, the heat dissipated by them under low loads is small. In this case, the fan or turbine of the cooling systems installed on them practically Continue reading

Reading books on a computer. How to read books on a computer?

I welcome all fans to read interesting and useful books, as well as those who are just interested in how you can read books on a computer. In the past two years, I myself have really loved reading, but in school it was completely different. Every day, at least an hour or less, I set aside useful material to read, it can be on the phone, on an e-book, on a laptop, on a computer, or just real printed books. At least anywhere that comes to hand, I read various books on all devices.

In general, the love of reading books came from my computer. When I began to sit down at my computer in debt, learned to make websites, make money on the Internet and so on, then I started reading books on my computer and I liked it. I have already read many different books, tried various programs! That is why today I Continue reading
