E-Business Hardware
– CPU
There are three key elements of a computer that determine its speed and capability:
- The speed of the central processing unit (CPU)
- The amount of random-access memory (RAM)
- The ability of the graphics processing unit (GPU)
The CPU is the brains of the computer. The faster the CPU the quicker the computer can perform tasks and exchange signals with the RAM.
– Network:
In business, computers needs to be connected together so they can share the data and information easily.
For internal, employee-only communication then a local area network (LAN) might suffice.
To connect the computers over large distance, we have to use Wide area network (WAN) using internet, intranets or extranet.
– Server:
Servers are used to manage network traffic, share data in applications and store data (if necessary). The more CPU speed and RAM that the server has the greater number of users who can access the network at once and the quicker the network will work.
– Backups:
The server holds a lot of vital information that is accessed and created by users. It will therefore be vital that this data is backed up regularly.
