gigahertz
The speed of most modern processors is measured in
clock speed, word size, bus width
The three factors that impact a processor's speed
multi- core- processor
Two or more complete processors residing on the same chip and can execute two or more sets of instructions at a time is called a
Embedded computers...
are integrated with a larger device
Hertz
Measure of clockspeed (cycles of internal operations per second)
gigabytes and terabytes
Measurements of hard drive capacities
ROM
The instructions needed to boot-up a computer, such as the basic input/output system (BIOS), are typically stored in
Machine cycle (fetch, decode, execute, and store)
Which important process is performed by the CPU? Machine cycle (fetch, decode, execute, and store)
Embedded computers..
are small computers integrated to part of a larger devices

Word Size
The amount of bits a processor can work with is referred to as
clock
The amount of instructions the CPU can process per second is dictated by the
Intel

L1
The small amount of memory, located within the CPU itself, is referred to as
ASCII
coding language uses 8 bits to represent a byte of information.
Server
computer system in a network that is shared by multiple users
Cahce
contains frequently accessed data and is much smaller than computer's RAM
Web Serve
controls access to resources on the web
External storage devices
devices that have: - optical DVD drive - universal serial bus (USB) - External hard drive
Hard Drive Space
is the amount of storage you have available to save data and information.
L3
memory located next to processor
Read-only- memory (ROM)
separate chips of storage (nonvolatile) that contain instructions not designed to be rewritten or removed.
Network Server
use to control access to resources like printers and applications
Which two of the following items are commonly included when you purchase a Windows PC laptop computer with a solid-state hard drive?
- An operating system -A universal serial bus (USB) port
CPU is..
- The CPU is integrated into a chip called a microprocessor. -The CPU is located on the motherboard of the computer. -CPU is the abbreviation for Central Processing Unit.
Clock speed
- aka: clock rate -is the speed at which the processor performs the operations required to run a digital device and instructions executed
All- in - one computers..
- house every component except the keyboard and mouse inside the same case as the monitor - are stationary devices with mother board behind monitor
Unicode
- many computer use _____which is a coding scheme using at least 16 bits to represent a character. - capable of representing world's lamguage
Solid- State Drive
- no moving parts - extremely fast - used in a variety of products including smartphones
Mainframe
- not designed to solve complex technical formulas - more powerful than a server computer - used by organizations to process large amounts of transactions
Traditional Hard Drives
- store data magnetically -have a platter - have a read and write head - commonly found in desktop computers
Boot Process
- the device is powered on and the CPU activates the BIOS - the power on self test is executed - the OS is loaded into RAM - OS check registry setting and loads saved configuration settings
Overclocking
-Changing processor setting so that computer runs faster than recommended by the manufacturer is called -can damage a processor if not properly executed. It will also void your warranty.
cache, l2 cache, or l1 cache
A high-speed storage area usually located directly on the CPU is called
Hyperthreading
A multicore processor has the ability to execute two or more sets of instructions at the same time. This is called
single core processor
A processor with one control unit and one arithmetic logic unit (ALU) is called a
