What is a router?
1. Concept
Router is a network equipment, providing routing and forwarding two mechanisms. Deciding to end packets from the source to a destination after the routing path (transmission path between the host and the host), a process called routing. Transfer the packet sent by the router to the appropriate router output end (inside the router), which is referred to as forwarding. Routing works at the third layer of the OSI model -- the network layer, such as the Internet protocol (IP).
2. Components
A router consists of the following major components:
● CPU
● ROM
● RAM
● NVRAM
● Flash Memory
● Interfaces
● Buses
● Power Supply
How to choose a router?
1. Fast and stable
This is the core function of router, but it depends on the routing USES chip solutions, system optimization, and WiFi technology. These feature can't see when we buy a router, unless the professional, the common user does not understand the meaning of these parameters.
At present, four big factories of routing chips is Broadcom, Qualcomm, MTK and Realtek.
There are three main types of current routing processor (CPU) architectures: MIPS, ARM, and Intel X86.
(1) MIPS has a long history in 32-bit and 64-bit embedded fields, is the most widely used. But the adoption rate for Android is the lowest among the three.
(2) The basic performance of ARM is higher than that of MIPS, and it is currently used in the flagship route of front-line manufacturers.
(3) Intel X86 is common in core devices such as servers
Overall processor chip is mainly to see the performance parameters, such as frequency and the size of the memory, don't really understand the buyers may focus on the brand (netgear, asus, Linksys these high-end routing ).
2. Srtonger WiFi signal
The ability to penetrate the wall is directly related to the wireless power of the router and the antenna gain. In theory, the router if placed in the same specifications down more, on behalf of the power, the higher the more antennas, the application of MIMO technology can also improve the transmission speed, the natural ability to wall performance will be better.
In addition, 2.4GHz and 5GHz is wireless signal spectrum, 2.4GHz is earlier than 5GHz, so 2.4GHz generality is better than 5GHz, but it also creates a 2.4GHz frequency band is too congested, while 5GHz band just can solve this problem. Therefore, the difference between the two can be summed up in two sentences: 5GHz WiFi is faster than 2.4GHz WiFi, about coverage, 2.4GHz WiFi is more extensive than 5GHz WiFi.
In addition, now the co-existence of the 2.4GHz and 5GHz form (double-frequency) has become a trend, dual-band WiFi devices the advantage of stronger anti-interference ability, more stable and the WiFi signal, faster transmission speed, so choose the dual-band router is positive choice.
3. Simple setting
The brand of smart router in this aspect is better. Xiaomi, Huawei, 360 these are all very simple. From the user's point, traditional route brands, TP-Link, tengda also follow up to make changes, new production model, set UI is relatively simple and practical.
4. More Functions: remote control, offline downloading, etc.
Now that routers are no longer just a network device, many brands add new features to their routers.Intelligent routing brands represented by Xiaomi are doing better.In addition, if you need a USB port and a built-in hard drive, you can pay attention to brands such as Xiaomi and Huawei.
5. The router needs to match the broadband in the home
We need to know that wireless signal quality is not only restricted by the router. Its most fundamentally are subject to the limitation of network bandwidth, such as your home broadband only 20M, so if you choose to gigabit router would be a waste. Because in the LAN environment, the wireless router with the larger M number, the wireless transmission speed (network speed) must be better, while the network speed of the Internet is determined by the broadband size. Namely 50M broadband, whether with 300M of the router, or 1200M of routers, while surfing Internet connection can only be biggest is 50M, so we also want to consider this point when the choose and buy, of course, if is for subsequent upgrade broadband, then certainly suggest you buy gigabit dual-band routers, saves on the subsequent upgrade equipment.
In addition, the network port of the router also needs to be aware. At present there are two kinds of gigabit and 100 megabytes. Gigabit nics transmission rate is 1000 megabits per second (gigabit), and a rate card (nic) ordinary transfer rate is 100 megabits per second (MB), gigabit nics and general network card is the biggest difference is that it so the transmission speed is 1000 megabits per second. It is ten times the MB network transmission rate.
