Types and Components of Computer System
This type of memory is volatile and loses its contents when power is turned off.
What is RAM?
This input device is used in fast-food restaurants and replaces a traditional keyboard with pre-set choices.
What is a concept keyboard?
A network covering a small area, such as one building, allowing resource sharing.
What is a LAN?
Compared to humans, robots do not get tired and can perform repetitive tasks without this.
What is getting bored?
This software allows creation of newsletters, posters, and leaflets using text boxes and images.
What is desktop publishing / word processing?
This computer component contains the Control Unit, ALU, and IAS and is known as the "brain" of the computer.
What is the CPU?
This optical media type can be written to many times, often used for recording TV programs.
What is CD/DVD-RW?
This device connects a LAN to the Internet by transferring data between networks.
What is a router?
This working arrangement lets employees choose when to start and finish work.
What is flexi-time?
These sensors read pulse rate, temperature, and respiration in hospitals.
What are vital-sign sensors?
This type of software translates high-level language step-by-step into machine code.
What is an interpreter?
This direct data-entry device reads characters printed in special magnetic ink, used in banking.
What is MICR?
A unique identifier for a device on a network that identifies its physical address.
What is a MAC address?
A microprocessor-controlled device category including washing machines, microwaves, and dishwashers.
What are labour-saving devices?
A system where barcode data is used to reduce stock levels and automatically reorder items.
What is automatic stock control?
This chip stores BIOS settings such as date, time, and system configuration and is non-volatile.
What is CMOS?
These storage devices are more reliable, lighter, and faster than HDDs but more expensive.
What are Solid State Drives (SSD)?
This change-over method runs both old and new systems side-by-side until ready.
What is parallel implementation?
One disadvantage of robots: they may require this when assigned entirely new tasks.
What is reprogramming?
Used in expert systems, this component stores knowledge gathered from experts.
What is the knowledge base?
This technology uses photons to make messages unintelligible to unauthorized users.
What is quantum cryptography?
This serial-access storage medium is used for batch processing such as clearing bank cheques.
What is magnetic tape?
A technique that converts information into meaningless form to prevent unauthorized reading.
What is encryption?
One advantage of microprocessor-controlled devices in homes is that they allow people to do this while the system works.
What is continue other activities / multitask?
This application uses sensors such as humidity, temperature, pH, and light to control plant growth conditions.
What is glasshouse environment control?
