It is kind of Electronic Machine that is powered by Electric
COMPUTER
What are the Basic components of Computer?
Hardware
Software
- The physical components of a computer system
Hardware
- These are the instructions that tell the computer what to do and how to do
Software
It is non-tangible that stored in digital form within computer memory
Software
Input and Output devices is under what component of computer?
Hardware
is any hardware component that allows the user to enter data into the computer.
input devices
Examples of Input Devices:
• Keyboard
• Mouse
• Scanner
• Microphone
• Digital Camera
• PC Video Camera
is any hardware component that gives information to the user
output device
Example of Output Devices:
• Monitor
• Printer
• Speaker
– responsible for the processing of information within the computer system.
Processing Devices
– considered as the brain of the computer
Central Processing Unit
–considered as the backbone of the computer
Motherboard
It retrieves and executes the instruction given by the software
Central Processing Unit
It is the intermediate stage wherein raw data is transform into information
Processing Devices
It connect some parts of a computer together
Motherboard
The two main categories of software:
System software
Application software
- The system software also called the __________which actually runs the computer.
operating system (OS)
is a program that allows users to a specific task on the computer.
Application software
• Word Processing Application
• Spreadsheet Application
• E-mail Application
• Internet Application
Examples of application software
It keeps data, information and instructions for use in the future.
Storage Media
Storage Media can also be called?
Storage medium and Storage device
Its work is not just for saving files, but it also can run task and application
Storage media
In storage media, saving data or information into storage devices
Writing
In Storage media, opening the data of information you saved on the storage devices.
Reading
- is the primary storage of a computer. When you’re working on a file on your computer, it will temporarily store data in your____.
RAM (Random Access Memory)
It allows you to perform everyday tasks like opening applications, loading webpages, editing a document or playing games, and allows you to quickly jump from one task to another without losing your progress.
RAM (Random Access Memory)
Considered as Volatile Memory/data
RAM ( Random Access Memory)
This is where the application software and operating system are stored, also considered as Non volatile memory/data.
ROM ( Read only Memory )
What are the Secondary storage?
Hard Disk Drives (HDD)
Solid State Drives (SSD)
are commonly used as the main storage device in a computer. it is often store operating system, software programs and other files.
These are magnetic storage devices.
Hard disk drives
This storage takes longer to transfer information and also vulnerable to damage and wet.
Hard Disk Drives
is a new generation of storage device used in computers. It replace traditional mechanical hard disks by using flash-based memory, which is significantly faster. also it don’t rely on magnets and disks, instead they use a type of flash memory called NAND.
Solid-state drives (SSD)
SSD use type of flash memory called ____ which means “not and”
NAND
- is a device which is plugged into your machine to give almost-immediate storage space, without the need to open or use your computer’s internal storage.
External hard drive
were the first widely available portable, removable storage devices. They work in the same way as hard disk drives, although at a much smaller scale.
Floppy disks
It was the first personal computer release without a floppy disk drive
IMAC
these disks are used for a lot more than just playing music and videos—they also act as storage devices, and collectively they’re known as optical storage devices or optical disk media.
CDs, DVDs, and Blu-Ray
– these are small, portable storage devices that have long been a popular choice for extra computer storage.
Flash memory devices
The most recognizable type of flash memory device is the?
USB flash drive
CD means?
Compact Disk
DVD means?
Digital Video Disk
it is the lates optical drives that is available
Blu-Ray
It is permanent and cannot be removed.
It is commonly use for software installation and it cannot be used as personal storage device.
CD/DVD-ROM
Recordable but cannot be Overwritten, You can insert data but it will be permanent (blank disk)
CD/DVD-R
Rewritable, you can continuosly write data on them and erase unwanted data, that’s why it is used as Storage devices.
Can be great help in Evidence.
DVD\CD-RW
