e) None of the above

Answers:
1)   ( a )
Explanation:
In computers and digital technology, a nibble  is four binary digits or half of an eight-bit byte. A nibble can be conveniently represented by one hexadecimal digit.
2)   ( b )
Explanation:
Byte,  the basic unit of information in computer storage and processing. A byte consists of 8 adjacent binary digits (bits). it can represent a number from 0 to 255.
3)    ( b )
Explanation:
SRAM – a type of memory chip which is faster and requires less power than dynamic memory.
4)    ( b )
Explanation:
In computer architecture, a bus is a communication system that transfers data between components inside a computer, or between computers.
5)    ( d )
Explanation:
A programming language such as C, C++, COBOL FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are consideredhigh-level because they are closer to humanlanguages and further from machinelanguages.
6)    ( c )
Explanation:
Linux, windows 2000, windows 2003, windows 2007/2008/2010…etc all are operating systems. With out operating system computers does not work.
7)    ( c )
Explanation:
RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes.RAM is the most common type of memory found in computers and other devices, such as printers.
8)    ( d )
Explanation:
Dots per inch (DPI, or dpi) is a measure of spatial printing or video dot density, in particular the number of individual dots that can be placed in a line within the span of 1 inch (2.54 cm).
9)    ( d )
Explanation:
Direct Thermal Printer, Thermal Wax transfer Printer.
10)    ( d )
Explanation:

An impact printer is a type of printer that operates by striking a metal or plastic head against an ink ribbon. The ink ribbon is pressed against the paper, marking the page with the appropriate character, dot, line, or symbol. Common examples of impact printers include dot matrix, daisy-wheel printers, and ball printers.
