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
