Main Components and Types of ERP Software

Business Intelligence (BI) is the core component or foundational pillar of an ERP system. BI begins by collecting the data and analyzing the same. Next, it generates numbers, tables, and visual reports from the analyzed data.
There are six main components in Enterprise Resource Planning (ERP). You can find them in the following list:

1. Human Resources
2. Customer Relationship Management (CRM)
3. Business Intelligence (BI)
4. Supply Chain Management (SCM)
5. Inventory Management
6. Accounting/Financial Management

There are four different types of ERP software. All of them have been listed below for your reference:

1. Box ERPs
2. Large Scale ERPs
3. Intermediate and Flexible ERPs
4. Industry Specific ERPs

How Does ErP Mode Work?

ErP works by providing instructions to the motherboard to stop providing power to all the connected devices when the computer is in S4 or S5 mode. Consequently, the connected devices won’t get the power, and the energy will be conserved.

Thus, the purpose of ErP is to save energy from being wasted when the computer is either shut down, sleeping, or on standby mode.

Unavailable Features in the ErP Ready BIOS Mode

Some features become unavailable in the ErP mode to fulfill the purpose of the same. Each unavailable feature has been described below for your reference:

• Power on during mouse click or movement

You can click on the mouse button or move the mouse to power on the PC while using a computer that doesn’t have ErP enabled on the same. However, the stated feature becomes unavailable once you switch to the ErP mode. Hence, now you won’t be able to power on your computer with the help of a mouse.

• Power on during the key press

The computers have a feature that can turn on your PC through the keyboard. It means that you can power on your PC by pressing a random key on your keyboard. However, the said feature would not be available on ErP-enabled computers.

• Wake on LAN

The system that usually wakes up with an incoming LAN signal won’t wake up with the same signal if ErP is enabled. Hence, the “wake on LAN” feature is disabled as well.

• Power Management Event (PME) wake up

The PME wake-up feature ensures that your computer is powered on again after you’ve shut down the same. But in the case of ErP, the stated action won’t take place, and your PC will remain in the shutdown mode until you turn it on by pressing the power button.

In Which Computer Modes Does ErP Operate?

ErP operates in the following computer modes:

• The shutdown mode

In the shutdown mode, all the processes of Windows and system services are shut down while the important data is saved to the disk. The shutdown mode is also known as S5 mode.

• The hibernate mode

In the hibernate mode, the computer’s state is saved in a “hibernate file.” The said file is then saved in the hard disk, while the other components are shut down to save the power until you come back. Hence, the given mode is known as the lowest power mode. Also, it ensures that you find the computer in the same state in which you left it without waiting for the bootup.

The hibernate mode is often referred to as the S4 mode.

What Does ErP Do When the Computer Is ShutDown?

After learning about the happenings in the shutdown mode, here you’ll see how ErP impacts the different aspects of the same mode.

• Consumption of power

Almost all of the components are shut down. No components except for the power button and few power source components get the power. Hence, only a small amount of power is consumed, while the remaining power is saved.

• Resumption of software

The state of the software is not maintained or saved. It means that all the processes and programs are closed completely. Now, they’ll need to be launched again for further use.

• The access time of hardware

The access time of hardware means the amount of time that a hardware component takes to respond to another device’s request. You can call the same “hardware latency” as well.

Note that the hardware latency is quite long as no device or LAN signal can power on your computer but you, the user.

• Hardware context retention

You won’t find any hardware context retained in your PC.

What Does ErP Do When the Computer Is in Hibernate Mode?

Moving towards observing the impacts of ErP on various aspects of the hibernation mode, here you go.

• Consumption of power

Similar to the ErP-enabled shutdown mode, you’ll see that almost all of the components are shut down. However, only the power button and a few power source components have access to the power. Hence, only a small amount of power is consumed while the rest of it is conserved.

• Resumption of software

The state of the software is saved in a “hibernate file,” as discussed above. It means that you won’t need to launch all of your programs again, and a complete boot-up won’t be required here. However, in the worst case, if a problem occurs in the hibernate file, then you’ll need to restart your PC to start working again. Also, the software state won’t be maintained due to the given scenario.

• The access time of hardware

The access time of hardware is long enough in the ErP-enabled to hibernate mode too. Similar to the shutdown or S5 mode, you’ll need to power on the PC by pressing the power button. No device or LAN signal would be able to perform the same action for you.

• Hardware context retention

Similar to the ErP-enabled shutdown mode, no hardware context is retained in your PC. However, the only difference between ErP-enabled S5 and S4 is that the former requires a full reboot, while the latter doesn’t. Hence, your hardware will continue working according to its previous state.

The Difference Between ErP and EuP

ErP is an abbreviation for energy-related products, while EuP stands for energy-using products. Also, ErP is the latest standard than EuP. Plus, it would be good to note that ErP also includes those products that consume electricity indirectly. It means that they aren’t directly connected to electricity, but they do have an impact on power usage. 

Water comes under the stated category of products.
