Study Notes
### Compter Peripherals and Memory
- A CPU is not a peripheral device.
- A keyboard, monitor, and mouse are peripheral devices..
- A port allows transfer of data between a variety of devices and computer.
- ROM (Read-Only Memory) is computer memory where the user cannot write new information or instructions.
- A byte is a group of 8 bits.
- A megabyte is equivalent to 1,024,000 bytes.
- Device drivers allow peripheral devices to communicate with the computer.
- The two basic types of memory in a computer are primary and secondary.
- A CD is a non-erasable disk that stores digitized audio information.
- Outputting is the process of producing useful information for the user.
- The output unit converts user input into computer-understandable form.
- A scanner is a device to convert printed documents to digital form.
- The smallest unit of data in a computer is a bit.
- A monitor looks like a television and is normally used with non-portable computer systems. It can be CRT or Flat panel monitors.
- Input and Output (I/O) devices are often called peripheral devices because they are in the external part of the computer.
- Data is a raw material used as input and processed data becomes information.
- Computer has a characteristic of speed, accuracy, and capacity.
- Memory is a place where data and information can be stored.
- The main memory depends on the size of the address bus.
- Secondary memory is independent of the address bus.
- MAR stands for Memory Address Register.
- Optical disks are a promising random access medium for high capacity secondary storage.
- The technology used in optical disks is a laser beam.
- The storage capacity of an optical disk is given by the number of sectors multiplied by the number of bytes per sector.
- The rotation of a disk must vary inversely with the radius of the disk.
- The tracks are divided into sectors whose size remains the same.
- The range of access times of optical disks are generally 100 to 300 milliseconds.
- DVD uses laser beam technology.
- A bar code reader is an input device.
- A supercomputer is the most powerful computer.
- A kilobyte is 1024 bytes.
- Memory management is the process of allocating memory to the program to keep them separate.
- A thin client has no hard disk.
- Earth stations send and receive satellite signals.
- A transponder ensures that outgoing satellite signals do not interfere with incoming signals.
- Cellular phones are least susceptible to noise.
- Token passing is a method used for network access.
- Centralized processing holds all data and processing in one site.
- Half-duplex allows data to be sent in both directions but in only one way at a time.
- A modem converts digital data to analog and vice-versa.
- A network is a group of computers connected together.
- A communication network can be wire or wireless.
- A web page is identified by a URL.
- The last part of the domain name is the top-level domain.
- A browser is used to access the internet and display Web pages.
- ARPANET was the first major computer network.
- The most used top-level domain is .com.
- A user can access a company's network using Telnet.
- A computer's primary storage is measured in bytes.
- An example of a computer's primary storage is RAM.
- A microprocessor clock's speed is measured in Hz.
- An example of a peripheral device is a printer..
- An operating system helps manage computer resources.
- A processor (CPU) is an electronic circuitry for executing instructions.
- Instructions are also called software.
- An instruction set is a set of instructions that a computer can execute.
### Computer Software
- A software program is a set of step-by-step instructions.
- Packaged Software is user-friendly and includes software documentation.
- Custom software is tailored to a specific business or user.
- An operating system is a set of software to manage computer resources.
- Application software is used to perform specific tasks.
- Word processing is a task-oriented program.
- Groupware software allows people to work together.
- Freeware software can be used for a limited time at no cost.
- Software piracy is illegal copying, distribution, etc.
- A site license allows a program to be used at multiple computer locations.
- A help desk is a place to resolve software and/or hardware problems.
