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

Mozilla Firefox Web Browser Overview

For more than 10 years I have been using the “Firefox” browser in my daily work on my PC and have gained a decent experience, which I hasten to share. This article is an introductory FAQ for beginners, which reveals and demonstrates the main features of the browser. This article is also a guide to setting up Firefox for beginners. So to say, “read before use.”

Most users simply install the browser and use it as is. Naked Firefox loses to WebKit browsers in a number of ways. At the same time, if we try to dress up (set up) the browser at least a little, then WebKit browsers (Chrome, Opera, etc.) will start to play strongly, and Firefox – vice versa. After all, with the help of extensions, this wonderful browser can be turned into an ultra-convenient assistant that can make work on the Internet many times more convenient.

Since Firefox can be configured for very different tasks, this review contains general (basic) setup instructions that Continue reading
