Computer Fundamental

note!Answer: A) Device manager
Device Manager shows installed hardware, its configuration and status.

note!Answer: B) W3C
The World Wide Web Consortium (W3C), founded by Tim Berners-Lee, develops and maintains Web standards.

note!Answer: C) Put data into secondary storage
Saving writes data permanently to secondary storage such as a hard disk.

note!Answer: A) Assembler
An assembler translates assembly (low-level) language into machine code.

note!Answer: D) File compression
WinZip is a utility that compresses files into archives (zip files) and extracts them.

note!Answer: B) Indicates an action to be performed during execution of assembled program
Imperative statements tell the machine what action to perform at execution time. Declarative statements, by contrast, reserve storage and associate names.

note!Answer: B) LIFO (Last in First out)
Nested macro calls are expanded in a stack-like manner, so the most recently started expansion finishes first. This is LIFO behaviour.

note!Answer: B) LIFO rule.
Nested macro calls are expanded using LIFO (last in, first out). This is the standard rule taught for macro processing.

note!Answer: D) synthesize the target program.
Pass I builds the symbol table and intermediate code. Pass II uses them to generate the final target (machine) program.

note!Answer: C) links the program with other programs needed for its execution.
A linker combines object modules and library routines the program needs into one executable. Relocation is done by the loader, and placing the program in memory is also loader work.

note!Answer: B) Secure it for transmission
Encryption protects data confidentiality, especially when the file is sent over a network.

note!Answer: A) low level programming language
Assembly language is a low-level language that closely maps to machine instructions.

note!Answer: C) machine dependant.
An assembler translates assembly code into machine code for a specific processor, so it is machine dependent.

note!Answer: C) Both (A) and (B).
Both block ciphers and stream ciphers are encryption techniques. 'Steam' in option B is a typo for 'Stream'.

note!Answer: A) information
Processing raw data produces meaningful information.

note!Answer: D) B and C
Data is raw and unprocessed, and processing it turns it into information.

note!Answer: A) Electronic Data Processing
EDP stands for Electronic Data Processing, the processing of data by electronic computers.

note!Answer: D) Input Method Editor
IME stands for Input Method Editor, used to type non-Latin scripts on a computer.

note!Answer: C) Remote Job Entry
RJE stands for Remote Job Entry, submitting batch jobs to a computer from a remote terminal.

note!Answer: B) Validation data
Validation checks that input data meets defined rules before it is processed.
