  Phase Sequence tester
• an instrument for detecting and measuring small electric currents?

  Galvanometer
• A device that measures the amount of electric energy consumed by a residence, a business or an electrically powered device?

  Electric meter
• What does vernier caliper measures?

  Circumference
• Explain resistance...
• refers to the process of measuring the computer components and objects to fully understand the needed requirements and capacity

  Mensuration
• is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage.

  Memory
• Megabytes

  1 million bytes
• Gigabytes

  1 billion bytes
• refers to how much disk space one or more storage devices provides.

  Data storage capacity
• stores data in a form of tiny magnetized dots.

  Magnetic media and storage devices
• have a relatively high storage capacity (up to few TB). They can be used for storing large quantities of data.

  Hard drives
• as external hard drive, is one that is mount in a small case along with some electronics that allows the hard-drive to be accessed using a USB link or similar connection

  Portable hard drives
• a kind of computer disk drive that reads and writes data from optical disks through laser beaming technology. 

  Optical storage devices
• disc that can hold around 800MB of data.

  Compact disk ROM
• Discs can hold around 4.7GB of data, dual-layer DVD can hold twice as much.

  Digital Versatile disk
• can hold data from 25-50 GB

  Blue ray disk
• can hold data up to 30 GB.

  HD DVD
• storage device that has no moving parts no reels of tape, no spinning discs, and no laser beams.

  Solid state storage
• also known as 'thumb- drives'-are non-volatile random- access storage devices.

  Memory sticks
• a kind of storage device that is used for storing media and data files.

  Memory card
• Called the CPU or central processing unit which is considered as the computer's 'brain.

  Processor
• The speed at which the CPU can execute the instructions is called the

  Clock speed
• The clock speed is measured in

  cycles per second
• It is a computer component that is used to enhance the quality of images showed on a display.

  Video card
• The information in computer is presented and stored in a

  Digital binary format
• can be used to represent the state of something that has two states

  Bit
• Each group of eight bits, such as the representations of letters and numbers, is known as a

  byte
• can be used to represent almost any type of information digitally: computer data, graphics, photos, voice, video, and music.

  Codes
• a German mathematician and philosopher, was  credited to have devised the modern binary number system
