Which is a machine-oriented high-level language for the GEC 4080 series machines.
Answer: C
Correct answer: Babbage
Babbage was the machine-oriented high-level language written for GEC’s 4080 series minicomputers, giving structured statements while still allowing direct access to the hardware. LOGO, SNOBOL and ALGOL were general languages not tied to that machine.

Cache memory is best described as ________.
Answer: C
Correct answer: a small, fast memory between the processor and main memory
Cache holds recently and frequently used data close to the processor, so the CPU does not have to wait for the much slower main memory. It is small precisely because the fast memory it uses is expensive.

The radix of a number system
Answer: C
Correct answer: Equals the number of its distinct counting digits
The radix, or base, of a number system is the count of distinct digits it uses: decimal has ten (0–9) so its radix is 10, binary has two so its radix is 2, hexadecimal sixteen. The radix also fixes each place value, since the \( n \)-th place is worth \( r^n \) - so it is fixed for a given system and need not be even.

When a document is opened in computer it is temporarily stored in ?
Answer: B
Correct answer: RAM
Opening a document copies it from the disk into RAM, the working memory the processor can reach quickly, and the edits are made to that copy. Because RAM is volatile the copy is lost if the power fails, which is why the file must be saved back to disk.

Laser printer is a type of ?
Answer: B
Correct answer: Non impact printing
A laser printer draws the page as a pattern of charge on a photosensitive drum, which picks up toner and transfers it to the paper, where heat fuses it. Nothing ever strikes the sheet, so it is a non-impact printer - unlike dot-matrix, daisy-wheel and line printers, where hammers or pins hit a ribbon against the paper.

Answer: B
Correct answer: DASD
A direct access storage device is abbreviated DASD, an IBM term for disk storage - a medium on which any record can be reached directly by its address, without reading everything recorded before it, as tape would require.

Which of the following software interacts with the hardware ?
Answer: C
Correct answer: System software
System software - the operating system, its drivers and its utilities - is the layer that deals with the hardware directly, issuing the commands that read a disk, drive a display or send a packet. Application software asks the system software to do that work rather than touching the hardware itself.

What is The capacity of 3.5 inch floppy disk?
Answer: D
Correct answer: 1.44 MB
The 3.5-inch high-density diskette holds 1.44 MB: 80 tracks a side, two sides, 18 sectors per track and 512 bytes per sector, giving \[ 80 \times 2 \times 18 \times 512 = 1{,}474{,}560 \text{ bytes} \] which is 1440 KB, quoted as 1.44 MB.
