Hardware consists of electronic components that input, process, output, and store data.

The central processing unit is referred to as the brain of the computer.

The CPU performs arithmetic and logical comparisons and stores results of operations in memory.

The speed and costs of central processing units are the same across multiple hardware vendors.

Some computers have two or more CPUs.

The CPU reads data and instructions from a read-only memory.

Optical disks are the most common storage devices.

USB connectors complicated the connection of peripheral gear to computers for users.

Main memory is also called cache memory.

A bit is represented either as a zero or a one.

A specification that a computing device has 100 million bytes of memory means that the device could hold up to 100 million characters.

A gigabyte is 1,024 terabytes.

An exabyte is 1,024 petabytes.

A terabyte is a larger unit than a petabyte.

A computer is faster if it has a large cache.

The CPU keeps rarely used instructions in the cache.

The CPU loads programs into the memory as chunks.

Constant memory swapping will reduce the speed of a computer.

Processing many programs at the same time needs lots of main memory.

When you work on a spreadsheet program like Excel, the program is loaded into the cache for processing.

A 64-bit CPU can address more main memory than a 32-bit CPU

Saving your work frequently is advised to tackle the issue of memory volatility.

A client computer can be part of a public network.
