• A server is a computer that is a meant to be a dedicated service provider, and a client is a computer that requests services.
• Before selecting the hardware and software components of a server, you should identify the server roles and network services that the server will need to provide and how many people will be accessing the server at once to help determine the load the server needs to fulfill.
• The primary subsystems that make up a server are processor, memory, storage, and network.
• The computer, including servers, is built around one or more integrated chips called the processor. It is considered the brain of the computer because all of the instructions it performs are mathematical calculations and logical comparisons. • A 64-bit processor is a processor with a default word size of 64 bits and a 64-bit external data bus, which allows you to access much more RAM than a 32-bit processor. • The amount of RAM can be one of the largest factors in your overall computer performance. • For the processor to communicate with the rest of the system, the processor plugs in or connects to a large circuit board called the motherboard or system board. The motherboard allows the processor to branch out and communicate with all of the other computer components. • Instructions that control most of the computer’s input/output functions, such as communicating with disks, RAM, and the monitor kept in the System ROM chips, are known as the BIOS (basic input/output system).
• The process of updating your system ROM BIOS is called flashing the BIOS. • While a server needs to have solid performance, the server needs to be reliable. • Virtual machines technologies enable multiple operating systems to run concurrently on a single machine.
• Windows Server 2008 R2 has organized the most common services into server roles. A server role describes the function of the server.
• Windows Server 2008 R2 Features are software programs that are not directly part of a role, or they...
