PCI express

A keyboard, a mouse, an operating system and a hard drive.

Consists of tangible objects, the actual machinery, physical parts of the computer.

Consists of algorithms and their computer representations: programs.

The cache memory is an internal memory of the CPU that stores the most frequently used instructions.

The cache memory is an internal memory of the CPU that stores all the instructions of the executing program.

The cache memory is an internal memory of the CPU. It is volatile and has a great capacity.

The cache memory is an internal memory of the CPU. It is non volatile and has a low capacity.

The extended ATX is the most common one so it is used in most computers.

Provides a physical interface for the interconnection of the other elements (processor, RAM memory, hard disk…)

Micro ATX and Mini ITX models are smaller and have more connectors for expansion cards and RAM memories than the standard ATX.

It handles large amounts of data and performs calculations at low speed.

It is placed in the motherboard by means of a PCI express socket.

Receives data from the input peripherals (keyboard, mouse…) or RAM memory.

Its cache memory determines the time it needs to complete a process.

It is placed on the motherboard, via dedicated sockets like the PCI slots.

It is a read/write memory and non volatile.

It is the one that stores the program to initialize the system.

It is a volatile read/write memory.

It is a memory which stores a program to initialize the physical components when the computer is turned on.

It is not in charge of checking these components to find posible errors or absence, like lack of RAM, CPU or hard disk.

It is a volatile memory which stores a program to initialize the physical components when the computer is turned on

Manages communications between the processor and the other elements of the motherboard.

If the RAM memory has a too large capacity the performance of the computer can be reduced.

Stores programs and data required by the CPU during the execution of a program while providing quick acces to the processor.

Stores programs and data required by the CPU during the execution of a program while providing slow acces to the processor.

Sends information to the hard drive when the CPU wants to run a program.

Main software of the computer system.

Software packages intended for the execution of specific tasks.

Each peripheral device has an specific program which needs to be installed in order to allow the operating system to communicate and control the device.

It manages hardware resources, programs and applications.

PCI slots are for expansion cards such the graphic card.

PCI slots are for expansion cards such as the sound card.

PCI express slot provides a higher data transfer and is used by hard drives.

All PCI slots have the same data transfer but different number of pins depending on the motherboard model.
