1. Which of the following computer languages is used for artificial intelligence?
A C
B COBOL
C PROLOG
D FORTRAN
E None of the above
C
Prolog stands for Logic Programming. It is used in artificial intelligence programming.
2. The brain of any computer system is _________?
A CPU
B Memory
C Control unit
D Arithmetic and Logic Unit – ALU
E None of the above
A
The brain of any computer system is the CPU (Central Processing Unit). The CPU is a chip containing millions of transistors. The job of the CPU is to perform the calculations necessary for the computer to function properly.
3. Which protocol provides a mail service between different hosts?
A FTP
B TELNET
C SMTP
D SNMP
E None of the above
C
SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used for sending and receiving e-mail. It is usually used with one of two protocols, POP3 or IMAP, allowing the user to save messages in a mailbox on the server and download them periodically from the server. SMTP is implemented to work on port 25.
4. The microprocessor was introduced in which computer generation?
A Second generation
B Fourth generation
C Both A and B are true.
D Third generation
E All the answers are true
B
The microprocessor brought the fourth generation of computers, with thousands of integrated circuits built on a single silicon chip. The Intel 4004 chip, developed in 1971, placed all of the computer’s components – from the Central Processing Unit (CPU) and memory to input/output controls – on a single chip.
5. A program that converts assembly language to machine language is called _______?
A Assembler
B Interpreter
C Compiler
D Comparator
E None of the above
A
An assembler is a program that takes basic computer instructions and converts them into a sequence of bits that the computer’s processor can use to perform its basic operations.
6. The binary system uses the base ______?
A 2
B 10
C 8
D 16
E None of the above
A
In the binary representation we use only two digits which are 0 and 1. So, we use only a binary number whose power is 2.
7. Which of the following languages is best suited for structured programming?
A PL/SQL
B FORTRAN
C PASCAL
D PROLOG
E None of the above
C
Pascal is more suited for structured programming, because Pascal was designed (in 1970 by Nicklaus) to force programmers to adopt a structured programming style. Pascal has successors, Modula and Oberon, which add modules and access to system resources.
8. ASCII means_______?
A American standard code for information interchange
B All purpose scientific code for information interchange
C American security code for information interchange
D American Scientific code for information interchange
E None of the above
A
ASCII(American Standard Code for Information Interchange) is the most common format for text files on computers and the Internet. In an ASCII file, each alphabetic, numeric or special character is represented by a 7-bit binary number.
9. Which of the following memories is non-volatile?
A SRAM
B DRAM
C ROM
D RAM
E All the answers are true
C
ROM is a non-volatile memory.
10. GUI means_______?
A Graph Use Interface
B Graphical Universal Interface
C Graphical User Interface
D Graphical Unique Interface
E None of the above
C
GUI (Graphical User Interface) is a graphical interface that allows users to interact with devices via graphical elements such as buttons, images and animations, unlike the console.
