Chapter 3 Computer Hardware Flashcards
It is the most obvious component of any information system
Hardware
What are the two(2) hardware devices
- Input Devices
- Output Devices
It acts as the brain of your computer.
Central Processing Unit (CPU)
What are the Three(3) Components of the CPU
- Memory or Storage Unit
- Control Unit
- Arithmetic and Logic Unit
This stores all the information and the instructions needed for processing.
Memory or Storage Unit
It is responsible for managing the transition between other units of a computer of data and instructions.
Control Unit
Operations such as addition, subtraction, multiplication, and division are performed.
Arithmetic
What are the two(2) subsections of the Arithmetic Logic Unit (ALU)
- Arithmetic
- Logic Section
Operations such as comparing, selecting, matching, and combining data are performed
Logic Section
It is the Computer’s storage space where data is to be processed and the instructions are necessary for processing are stored
Computer’s Memory
What are the three(3) Primary Types of memory
- Cache Memory
- Primary Memory / Main Memory
- Secondary Memory
It is the CPU’s internal memory for storing data, program, and program output. It is a read / write memory that stores data before the computer is running. As soon as the computer is turned off, the data is removed.
Random Access Memory (RAM)
What are the two(2) types of RAM
- Static RAM (SRAM)
- Dynamic RAM (DRAM)
A memory we can only read from, so we cannot write on it. This memory form is non-volatile. The knowledge is permanently preserved in such memories during development.
Read Only Memory (ROM)
What are the four(4) types of ROM
- Masked ROM (MROM)
- Programmable Read Only Memory (PROM)
- Erasable and Programmable Read Only Memory (EPROM)
- Electrically Erasable and Programmable Read Only Memory (EEPROM)
It is also known as MB, Mainboard, mboard, Mobo, Mobd, Backplane Board, Base Board, Main Circuit Board, Ect,. alam nyo na yan
Motherboard
The amount of data that can be stored in the storage unit is called ____________. In terms of bytes, this storage ability is represented.
Computer Memory-Units
What are the Seven(7) Data units in the Memory
- Bit (Binary Digit)
- Nibble
- Byte
- Kilobyte
- Megabyte
- Gigabyte
- Terabyte
The unit that most computers use to represent a character such as letter, number or typographic symbol ( For example, “g” , “5”, or “?”).
Byte
This is a single memory unit and only 2 possible binary values can be stored, either 0 or 1
Bit (Binary Digit)
It its a group of 4 bits or half a byte.
Nibble
It is numbered 1024 bytes. It is also referred to as 1000 bytes when talking about data storage instead of computer memory.
Kilobytes
It is numbered 1024 kilobytes. It is also referred to as 1000 kilobytes when talking about data storage instead of computer memory.
Megabytes
It is numbered 1024 megabytes. It is also referred to as 1000 megabytes when talking about data storage instead of computer memory.
Gigabytes
It is numbered 1024 gigabytes. It is also referred to as 1000 gigabytes when talking about data storage instead of computer memory.
Terabytes
Also known as Headphone Jack
3.5mm Audio Jack
What year did the first 1 TB hard drive was made?
2007
RJ-45, Gigabit ________, 10/100 ________
Ethernet
This popular port is the most common one for connecting to TVs and also appears on many external monitors and projectors.
HDMI(High Definition Multimedia Interface)
With the ability to output to a single monitor at 4K resolution and 60hz, or up to three monitors at full HD (using a hub or dock), it is the most advance display-connection standard today.
DisplayPort / mini DisplayPort
Also known as Dual-Link
DVI (Digital Visual Interface)
Also known as the microSD slot
microSD card reader
3-in-1 card reader, 4-in-1 card reader, 5-in-1 card reader
SD Card Reader
Also known as the Regular USB
USB / USB Type - A
Also known as High-Speed USB
USB 2.0
Also known as SuperSpeed USB
USB 3.0
Also known as SuperSpeed+ USB, SuperSpeed USB 10Gbps
USB 3.1 Gen 2
Also known as Micro-B
Micro USB
Hard-Wired Computers containing a pre-programmed set of data or instructions were the very first ROMs.
MROM (Masked ROM)
It’s a read-only memory that a user can only change once.
PROM ( Programmable Read Only Memory)
By exposing it to ultraviolet light for a time of up to 40 minutes, it can be erased.
EPROM (Erasable and Programmable Read Only Memory)
It is electrically programmed and erased. Around ten thousand times, it can be deleted and reprogrammed. Both Programming and erasing take between 4 to 10 ms (miliseconds).
EEPROM (Electrically Erasable and Programmable Read Only Memory)
