Algorithm

• is simply a list of instructions that describe how to do
  a particular task.
  
• Starting up a computer
  
• The speed at which the processor carries out instructions
  
• A technology for storing data in an electronic format
  which is used for memory cards. e.g. USB, memory cards.
  

BIOS

• . It checks that the computer
  hardware is all present and working correctly when you power up a
  computer system
  
• The speed at which the processor carries out instructions,
  measured in Megahertz (MHz) or Gigahertz (GHz).
  
• A technology for storing data in an electronic format
  which is used for memory cards. e.g. USB, memory cards.
  
• 210 bytes exactly, or about 1000 bytes.
  

Bit

• Either a 0 or a 1
• 8 sets of 8 or 1
• 1024 sets of 0 or 1
• The measurement of speed in a network

Cache Memory

• Very fast access memory which is close to the processor and stores
  frequently used data.
  
• A technology for storing data in an electronic format
  which is used for memory cards. e.g. USB, memory cards.
  
• a group of 4 bits.
  
• holds part of a program that starts running
  when a computer is switched on.
  

Virtual Memory

• when the computer uses some of its hard disk
  space as if it were RAM.
  
• When you switch the power off, all the contents will be los
  
• where the workstations are 'further
  apart' from each other. WANs are usually made up of LANs connected
  together
  
• his is the place where the computer
  stores programs and files it is using at the moment.
  

The PCs on a network are connected to a ______. It manages
lots of connections with computers at the same time and lets them all
communicate with the server.

• Hub or Switch
• Memory Drive
• USB
• HTTPS

Dynamic IP Address

• changes all the time and is allocated by other equipment
  on the network automatically.
  
• Transferring files over the internet
  
• software system which is designed and developed specifically for
  a purpose or company.
  
• Very fast access memory which is close to the processor and stores
  frequently
  

Protocols

• When two devices want to successfully communicate, they must
  agree to follow some rules about the way they will do it.
  
• Memory devices which keeps its data without power and has no
  moving parts.
  
• when the computer uses some of its hard disk
  space as if it were RAM.
  
• When you switch the power off, all the contents will be lost. e.g. RAM
  

Where the workstations are 'further
apart' from each other. 

• WAN
• LAN

Peripheral Device

• Any hardware device which is connected to the
  computer and controlled by CPU.
  
• This is the place where the computer
  stores programs and files it is using at the moment.
  
• ROM holds part of a program that starts running
  when a computer is switched on.
  
• Simple Mail Transfer Protocol
