Banks read the account and cheque numbers printed at the foot of a cheque with which technology?
D. Magnetic ink character recognition (MICR)
Cheque codes are printed in magnetic ink and read by MICR, which resists forgery and works even if the code is overwritten. OMR reads shaded bubbles on answer sheets, RFID reads radio tags, and OCR converts printed text images to text.
Which generation of computers is defined by the use of integrated circuits?
D. Third generation
Textbook generations: first, vacuum tubes; second, transistors; third, integrated circuits; fourth, microprocessors built by very-large-scale integration. The fourth generation also uses integrated circuits, but it is defined by the whole CPU on one chip.
The core part of an operating system that stays in memory and manages processes, memory and devices is called the:
B. Kernel
The kernel is the resident core of the OS. The shell is the user's command interface to it, the boot loader only starts the kernel, and a device driver is a module that lets the OS control one kind of hardware.
An operating system that must respond to a sensor within a guaranteed time limit, as in an automatic milking or irrigation controller, is a:
D. Real-time operating system
Real-time systems guarantee a response within a fixed deadline. Batch systems run queued jobs without interaction; time-sharing gives users turns but no deadline guarantee; network operating systems provide file and print services to clients.
A computer is so short of RAM that it spends most of its time moving pages between memory and disk and little time doing useful work. This condition is called:
D. Thrashing
Thrashing is excessive paging that starves useful work; the cure is more RAM or fewer simultaneous programs. Spooling queues output to a device, deadlock is processes waiting on each other's resources, and fragmentation is scattered free space.
Which SQL command belongs to the data definition language?
D. CREATE
DDL defines structure: CREATE, ALTER, DROP, TRUNCATE. SELECT is data manipulation (or query) language, GRANT is data control language and COMMIT is transaction control.
A table of 120 farmers is cross-joined with a table of 5 crops. How many rows does the result have?
D. 600
A cross join returns every combination, m × n = 120 × 5 = 600. 125 adds the tables; 120 is what an inner join would give if each farmer matched exactly one crop; 24 divides.
Which protocol is used to send email from a client to a mail server?
C. SMTP
SMTP (Simple Mail Transfer Protocol) sends and relays mail. POP3 and IMAP retrieve mail from the server; FTP transfers files.
A cooperative uses hosted accounting software through a web browser and manages nothing but its own data and users. Which cloud service model is this?
C. Software as a service (SaaS)
Using a finished application while the provider runs everything beneath is SaaS. In IaaS the customer manages the operating system and applications; in PaaS the customer deploys its own applications; on-premises hosting is not a cloud service model.
A caller claiming to be from a farmer's bank asks him to read out the one-time password just sent to his phone. This is an example of:
B. Vishing
Vishing is voice phishing by telephone. Smishing uses text messages; IP spoofing forges network addresses; denial of service floods a system. Banks never ask customers for their OTP.
