Study Notes
Computer Peripheral Devices
- CPU is not a peripheral device
- Keyboard, monitor, and mouse are peripheral devices
System Unit Components
- A port is a place that allows data transfer between various devices and a computer.
Memory Types
- ROM (Read-Only Memory): User cannot write new information or instructions to this memory.
- CPU can operate on data from secondary storage after it is loaded into RAM.
Data Units
- A byte is a group of 8 bits.
- A megabyte equals 1,000,000 bytes.
Input/Output Devices
- Device drivers allow input/output devices to communicate with the computer system.
Computer Memory
- The two basic types of computer memory are primary and secondary.
Optical Storage Devices
- A CD is a nonerasable disk used for storing digitized audio information.
Output Unit Function
- The output unit converts user input into a computer-understandable format.
System Component
- A scanner is a device used to give digitized form of printed papers.
Computer Monitors
- CRT monitors are similar to televisions and are used with nonportable computers.
- LCD, flat panel, and LED monitors are lightweight and used in portable and non-portable computer systems.
Input Unit Function
- It reads instructions and data from outside the computer world.
- It does not convert the data into a usable format for human understanding.
- It does not include converting or formatting data for human understanding.
Data
- Data is the raw material used as input for processing. This creates information.
Computer Characteristics
- Speed, accuracy, and capacity are characteristics of computers, not IQ.
Memory
- Memory is an electronic holding place for data retrieval later.
Memory Size
- The size of main memory depends on the size of the address bus.
Memory Types (Independent of Address Bus)
- Secondary memory
MAR
- MAR stands for Memory Address Register.
Optical Disks
- Optical disks are a promising random access medium for high-capacity secondary storage.
Optical Disk Technology
- Optical disks use laser beam technology.
Optical Disk Storage Capacity
- The capacity of an optical disk is calculated by multiplying the number of sectors by the number of bytes per sector.
Disk Rotation
- Disk rotation must vary inversely with the radius of the disk.
Disk Sectors
- Disk sectors maintain a constant size.
Optical Disk Access Time
- The access time for optical disks typically ranges from 100 to 300 milliseconds.
Laser Beam Technology
- Laser beam technology is used in optical disks.
RAID
- RAID (Redundant array of independent disks) is a method to combine multiple disk packs for a storage unit function.
Updating In Place
- The process of updating a disk record to its original location.
Scrolling
- Moving a page up or down on a computer screen.
Harmful Programs
- A virus is a harmful program.
Recently Used Data/Programs
- Recently used data is swapped into memory.
Storage Unit
- The storage units hold data and instructions to be made readily available.
Vertical Market Software
- Software written specifically for a given business type.
Software Piracy
- Making illegal copies of copyrighted software.
Desktop Publishing Software
- Software used to create professional newsletters and reports.
Database Management Software
- Software used to store, update, manipulate, and retrieve data.
Commercial Software
- Packaged software
Office Suites
- Antivirus software is not typically included in office suites.
Emulation
- Software that makes a personal computer function like a terminal.
Browser
- Software on a user's computer that provides a graphical user interface for accessing the Internet.
Web Site
- A website is a location on the World Wide Web.
Protocol
- TCP/IP is the protocol used to facilitate communication on the internet
Thin Client
- This is a stripped-down computer that accesses network resources.
Earth Stations
- Devices used to communicate with satellites
Transponder
- Devices used in satellite transmission
Digital Medium
- A cellular phone is the least susceptible medium to noise.
Token Passing
- A method used by Token Ring networks to control network access.
Client/Server Relationship
- Processing done by a server and access by a client.
Distortion
- Distortion in a signal is called noise.
Data Representation
- Data is represented by the binary system (0s and 1s).
Computer Memory Unit
- The term "memory" is often used in place of primary storage, used for the rapid retrieval of data.
CPU Components
- A CPU has two parts: The Control Unit and the ALU (Arithmetic Logic Unit).
Machine Cycle
- A machine cycle is the time necessary to take the steps to fetch, decode, execute, and store an operation.
Computer Software
- Software is step-by-step instructions to run the computer.
Computer Types
- Microcomputers are desktops and personal computers.
Computer Data
- Information is processed data.
Computer Units
- Printers and screens are output units.
CPU Functions
- The CPU does calculations, moving and processing data. It executes instructions and interacts with memory and other computer components.
Computer Coding
- ASCII is the most widely used coding scheme.
Computer Memory
- RAM stores data to be accessed quickly for processing.
Computer Memory
- RAM is a volatile memory- loses data when power is off.
Computer Storage
- Secondary storage devices are long-term, and data remains stored when power is off.
- The secondary storage holds data that is not immediately needed for processing.
Computer Components
- CPU contains the Control Unit and the ALU, which perform the calculations.
