For many beginners, the ROM Monitor of Cisco routers is often unfamiliar or even daunting. The reason is very simple. First, we do not often use this mode and are not familiar with its related operations; second, Operation errors in ROM Monitor mode often cause fatal damage To routers, such as destroying IOS files in flash, resulting in system crashes. So many people put their hands on it and are discourage
I believe most people have come across a computer disc and can't read it, in the optical drive, the computer can not read the CD-ROM, the optical drive emits a "squeak" sound, some CD files and directories cannot be read, or the entire CD is unable to read, and even sometimes the CD-ROM sound like a motor to make the entire machine crash.
Why can't the disc read out, the disc can not read out how to do? It
First, the CD-ROM reload computer system
1, restart the computer, start to hold down the DEL key, enter the BIOS settings, set up the computer to start the CD-ROM drive.
2, the system CD into the CD-ROM drive, restart the computer.
3, follow the prompts to operate, installation system.
4, System installation and then install the motherboard driver, graphics d

Non-Android devices. I believe that most of the camera friends choose Android phones to view their high customization and playability. The Android system has been continuously updated over the past five years, and its fluency and system functions have become increasingly improved, in addition to the native Android systems favored by many enthusiasts, custom UIS such as HTC Sense, Samsung touwiz, and Xiaomi miui all cultivate their fans with high-quality u

Miui rom has the "" vulnerability to obtain system permissions, text messages, passwords, and other important data.
All miui rom versions on Xiaomi official website have system permission vulnerabilities. Any APK can exploit this vulnerability to obtain the same permissions and data as ROM vendors, attackers can steal system application data (such as text messag
the stored data, but SRAM does not need it. DRAM has a long access clock interval, while SRAM is fast and time-consuming. DRAM consumes low power, high power consumption of SRAM.
At present, the price of the same capacity of SRAM is about 8 times that of SDRAM, and the area is nearly 4 times larger. Therefore, SRAM is often used for fast storage of low-capacity Ram requirements, such as cache (cache ), for example, the L1 cache in the CPU and the L2 cache on the motherboard are usually only sev
Rom and RAM are both semiconductor memory, Rom is short for read only memory, and Ram is short for random access memory. ROM can still maintain data when the system stops power supply, while Ram usually loses data after power loss. A typical Ram is the computer memory.Ram has two categories: static RAM (static RAM/SRAM ), The fast speed of SRAM is the fastest rea
The Android system is also an OS, and is based on the Linux kernel.ArticleFrom the perspective of operating system exploration, we can understand the Android system from practice, so as to better use the Android system and even transform it.

ROM: read only memory, read-only memory
It is a kind of semiconductor memory, also called non-volatile memory. The feature is that once data is stored, it cannot be changed or deleted. The stored data will not disappear because the power supply is off.

Many friends have added an acpi slic table to the BIOS to activate OEM Windows Vista (Windows 7 ?) It is a great deal of fun. They have mature tool chain support for legacy bios. Tools that exit from the BIOS factory can help you easily add a new SLIC table to Rom to activate windows.
However, uefi bios is not that simple. The current motherboard 100% that can be modified is legacy. I have never heard of anyone who can successfully modify the UEFI mo
Q: Can I tell you how to enter the ROM status?
A: There are different ways for cisco routers to enter the rom status. However, the following three methods can be used to enter the rom status. during use, you can try to enter the rom status.

Common Memory Concepts: RAM, SRAM, SDRAM, ROM, EPROM, EEPROM, flash memory can be divided into many kinds, which can be divided into RAM (random access memory) and ROM (read-only memory) according to the loss of the power-down data, where the RAM access speed is relatively fast , but the data is lost after power-down, and the data is not lost after the ROM is dro
