0. Reply content: If you use Node. js, can you use it if you don't need npm to pull dozens of hundreds of megabytes of data? The python installation package looks like a dozen mb. It was just yesterday that node was used. During the installation, it was only 5 MB in size and thought it was lightweight.
When you started writing code, didn't you always download various packages from npm?
In a project, there are more than 10 MB of npm packages, not a s
. The tiny fiber is encapsulated in a plastic sheath, allowing it to bend without breaking. Typically, the transmitter at one end of the fiber uses a light emitting diode,led or a laser beam to transmit the optical pulses to the fiber, and the receiving device at the other end of the fiber uses a photosensitive element to detect pulses. In daily life, optical fiber is used as a long-distance information transmission because the conduction loss of light in optical fiber is much lower than that of
When we choose VPS, Server host, we often see the common MB, GB, Mbps, and so on some of the labeling units. Most of us will probably know MB (megabytes), which is much larger than the amount of memory we often use. But if the bandwidth is involved in Mbps, it may be a bit difficult to understand, such as we often see that there is 2Mbps bandwidth, many people wi
Oracle 12C r2-new features-pdb disk I/O (iops,mbps) resource managementIn previous versions, there was no easy way to control the amount of disk I/O used by a single PDB. As a result, a PDB may run out of disk I/O and affect the performance of other PDB in the same instance. The Oracle 12c R2 can control the amount of disk I/O used by the PDB and is more harmonious with multi-pdb.1 Introduction to I/O parametersSome of the following parameters can be
LocVPS, a Chinese VPS host provider, has many other host brands, such as Weixiang host and HostXen, which are also the same host Brand of the same boss. Their products are similar, to some extent, we can cover the user market with a high probability of packaging different brands. The LocVPS platform uses Xen-based VPS host products, including VPS hosts for data centers in Sha Tin, Hong Kong PN, MC, and Peer1.Currently, LocVPS provides upgraded configuration of the CN2 line in Sha Tin, Hong Kong,
After the Android phone successfully connects to the GHZ wireless signal of the 11N router, the current wireless speed is usually 72 Mbps (or 65 Mbps) on the phone, as shown in the figure below:Note:: The wireless rate cannot be viewed on iOS mobile phones.This is because the Wi-Fi module of the mobile phone only has one built-in antenna and only supports 20 MHz bandwidth. Therefore, after the mobile phone
Mbps and MB/s represent a different network transfer speed, and MB/s is 8 times times the Mbps.MBPS=MBIT/S is the abbreviation for megabits per second (Million bits by second). BPS (bits per second), which is the common unit of bit rate, bits/sec, bits/sec, transfer bits per second, data transfer rate .The size of the file is usually referred to as 8MByte. BYTE (byte) is a unit of measurement used by computer information technology to measure storage
Network server bandwidth Mbps, MB/s, MB/s differenceThe meaning of MB/s is megabytes per second, MB/s means megabits per second, the former refers to the number of bytes transmitted per second, the latter refers to the number of bits transmitted per second. The two are completely different.The so-called 10M bandwidth, in fact, refers to 10Mbps (megabits)Computational bandwidth theory fastest download speed:
between B and B.2. What is the download speed of 2 Mbps?
First:2 m/s = (2*(10 ^ 6)/8 B/S = 250000 B/S
Explanation: we need to convert the 2 Mbit/s network speed to the download speed. 2 Mbit/s = 2*(10 ^ 6) B/S, at this time, we get the data volume of B (B/S) transmitted per second (in lower case, bit.
Because a B represents 8 B, 2 m/s = 2*(10 ^ 6)/8 B/S = 250000 B/S, at this time, we get the amount of B transmitted per second (B/S, note that it is ca
Cacti self-brought traffic monitoring threshold template for "interface–traffic", can only monitor bytes, after adding thresholds, alarm traffic information in bytes units, viewing is unfriendly, you can convert Btyes to MB units by the following methods.1, add the Traffic conversion template, open the Control Panel management function, find cdefs:2, click Add in the top right corner of the page, the following page appears:This function is named as: Turn Bytes to Mbits, after saving, we create a

Among the many Internet Access Technologies, the emerging Power Line Communication technology is particularly eye-catching. The power supply's online network speed can reach 200 Mbps. This absolute advantage will threaten the Traditional Ethernet access power cord communication technology, the basic principle is to use existing power lines to achieve high-speed transmission of data, voice, images, and other multimedia business signals, and load data s

When we configure hardware devices, we often see some wireless network protocol standards. The protocol standards vary with hardware. The wireless network card of the notebook is often labeled as 802.11a/B/g or 802.11a/g/n. In fact, it refers to the wireless network protocol, it can be divided into 802.11a, 802.11b, 802.11g, and 802.11n. these different wireless protocols have evolved from 802.11. 802.11 is a wireless LAN Standard originally developed by IEEE, it is mainly used to solve the wire
