Answers:

Q1. a
 (First Generation (1940-1956) Vacuum Tubes. The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.)

Q2. d
 (Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers.)

Q3. c
 (Basic is a very powerful language as a tool for the novice programmer. Basic allows for a wide range of applications, and it has many versions. However, as long as the emphasis is on the techniques of programming and problem solving, the specific syntax is easy to follow.)

Q4. e
 (A computer keyboard is one of the primary input devices used with a computer that looks similar to those found on electric typewriters, but with some additional keys. The modern keyboard is based on the typewriter, a typing device that was first developed and patented in 1868 by Christopher Sholes.)

Q5. c
 (Worksheet formulas are built-in functions that are entered as part of a formula in a cell. These are the most basic functions used when learning Excel. VBA functions are built-in functions that are used in Excel's programming environment called Visual Basic for Applications (VBA).)

Q6. a
 (An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).)

Q7. c
 (A high-level language is a programming language such as C, 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 considered high-level because they are closer to human languages and further from machine languages.)

Q8. d
 (A semiconductor is a substance, usually a solid chemical element or compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current.)

Q9. a
 (Terminal is a term used to describe a group of hardware devices that commonly consists of a keyboard and a monitor that enables a user to communicate with the internal CPU or another network device or computer.)

Q10. b
 (A database management system (DBMS) is system software for creating and managing databases. The DBMS provides users and programmers with a systematic way to create, retrieve, update and manage data.)
