How Can I Improve Desktop Computer Security?

A desktop computer is an independent phase-separated computer that is completely unconnected with other components. Compared to laptops and netbooks, it is relatively large. The host, monitor, and other devices are generally relatively independent. On the workbench. Hence the name desktop.

Desktop PC

A desktop computer is an independent phase-separated computer that is completely unconnected with other components. Compared to laptops and netbooks, it is relatively large. The host, monitor, and other devices are generally relatively independent. On the workbench. Hence the name desktop.

The advantages of desktop computers are durability and affordable. Compared with notebooks, they are better configured at the same price and have better heat dissipation. If the accessories are damaged, the replacement price is relatively cheap. The disadvantages are: bulky and large power consumption.

Software system

Software system includes: operating system, application software, etc. Management software for the computer industry in application software, an essential tool for the development of the IT computer industry,

Computers can be divided into analog computers and

Computer equipment must be powered off properly, otherwise it will affect its working life and is the culprit of some failures. The correct computer power-on and power-off sequence is: power on, first turn on and turn on the computer's peripheral devices (such as monitors, printers, etc.), and then turn on the computer host; the shutdown sequence is the opposite, turn off the host power, and then disconnect Power for peripherals.

Second, computer equipment safety instructions

(1) Computer equipment should not be placed in dusty places (such as windows near the roadside, etc.)

The first aspect starts with the central processing unit and the fan. The central processing unit is referred to as the CPU and the central processing fan is referred to as the CPU.

I'm afraid the difference is obvious. The desktop occupies a large area and the notebook is easy to carry.

In terms of internal structure, the architecture of desktops and notebooks is the same. It's just that due to space limitations of laptops, many devices are integrated with the motherboard.

Both the CPU and the graphics card are soldered to the motherboard (it seems that some graphics cards are not soldered). Therefore, the laptop cannot replace the CPU and graphics card separately.

Due to many reasons such as limited battery life and difficult cooling due to small space, the hardware inside the notebook mostly appears in the form of a low-power version. For example, the processor is called the mobile version (Pentium M = Pentium Mobility), and the graphics card is also the mobile version (AMD-ATI is called Mobility Radeon, nVidia is called GeForce Go!), Which are actually low-frequency and low-power versions to reduce heat emission and power Consumption. Therefore, the performance of the same level of equipment, the mobile version also shrinks. At the same time, there must be complete cooling measures inside the notebook in accordance with the model design. These measures are usually designed separately, which is different from desktop computers.

In addition, due to integration reasons, laptops generally come with more devices, such as Bluetooth and infrared, which are basically standard. Centrino models also have 802.11a / b / g wireless network cards. Apple computers also have 802.11n devices. These devices allow notebooks to cope with more situations.
