DAY 13

Processor AKA: central processing unit (CPU) The CPU or processor is the "brain" of the computer. It performs all the operations that the computer does, from simple encoding of text to complex rendering of video. So, the faster the speed of your processor, the faster your computer will run.

MEASUREMENTS: • SPEED: GHz example: 3.5GHz • CORES: number of example: quad core BRAND NAMES: • Intel • AMD Objective: • Learn the parts of a computer DAY 18

Memory AKA: Random-access memory (RAM) Usually referred to as "memory", RAM is second to the CPU in determining your computer's performance. It temporarily stores your computer's activities until they are transferred and stored permanently in your hard disk when you shut down or restart

MEASUREMENTS: • SIZE: GB (Gigabyte) example: 4GB NOTE: • The more memory your computer has, • the faster it will respond. Objective: • Learn the parts of a computer DAY 18 Hard Drive The hard disk drive, more commonly known as the hard drive or hard disk, is where all data and programs are stored in your computer permanently, unless you delete them. Generally speaking, a hard disk with a higher capacity is always better.

MEASUREMENTS: • SIZE: GB or TB (terabyte) example: 500GB or 2TB • TYPES: Disk or Solid State

Objective: • Learn the parts of a computer DAY 18 Motherboard The motherboard is where all the other devices in your computer such as the processor, memory, hard disk, and CD/DVD drives are connected. To prevent problems that may lead to loss of data in the future, choose a good quality motherboard.

Objective: • Learn the parts of a computer DAY 18 Optical Drive An optical drive is any storage device that uses light to read and write information.

TYPES: CD, DVD, and Blu-ray drives.

Objective: • Learn the parts of a computer DAY 18 Monitor A monitor or a display is an electronic visual display for computers. The monitor comprises the display device, circuitry and an enclosure.

MEASUREMENTS: • SIZE: Inches example: 21 inch • INPUTS: HDMI, DVI, SVGA • RESOLUTION: number of distinct pixels • NTSC (480i) • 1280 x 720 (720p) • 1920 × 1080 (1080i) Objective: • 4k • Learn the parts of a computer DAY 18 Peripherals Peripherals are devices that, are commonly used in conjunction with a computer.

EXAMPLES: • Keyboard • Mouse • Speakers • Printer • Camera

Objective: • Learn the parts of a computer DAY 18 Operating System An operating system is a program designed to run other programs on a computer. A computer’s operating system is its most important program. It is considered the backbone of a computer, managing both software and hardware resources. Operating systems are responsible for everything from the control and allocation of memory to recognizing input from external devices and transmitting output to computer displays. They also manage files on computer hard drives and control peripherals, like printers and scanners. EXAMPLES: • Windows (Windows 8) • OSX (Snow Leopard) Objective: • UNIX • Learn the parts of a computer

DAY 18 Software or as you call it Apps Computer software, or just software, is any set of machine-readable instructions that directs a computer's processor to perform specific operations.

EXAMPLES: • PowerPoint • Word • Instagram • Photo Shop • Chrome

Objective: • Learn the parts of a computer
