SEE COMPUTER SCIENCE 2076 Compiled by: Deepak Shrestha Networking and Telecommunication

Questions and Answers [70] 1. Communication Communication is sending and receiving information between two or more persons.

2. Telecommunication [MFT 2075] Telecommunication is a system of transmission of sounds, images, texts or data in the form of electronic signals.

3. Data Communication [SLC 2067] Data communication is a process of transferring data electronically from one place to other using different transmission mediums. Eg. E-Mail, Chat and phone calls.

Components of Data Communication. i) Data ii) Sender iii) Medium iv) Receiver v) Protocol

4. Medium A path through which the sender makes communication to the receiver is known as medium.

5. Protocol [MFT 2075] Protocol is a set of rules by which computers on the network communicate with each other. E.g. TCP/IP, SMTP, HTTP etc.

6. Data Transmission Mode [MF 2076] Data transmission mode is the way of transmission of data from one location to another. There are three types of transmission mode: i) Simplex mode ii) Half duplex mode iii) Full Duplex Mode

7. Simplex mode [MF 2076] The transmission mode in which transmission of data can take place in one direction only is called simplex mode. E.g.: Newspaper, Radio and Television.

8. Half duplex mode [MF 2076] The transmission mode in which transmission of data can take place in both directions but only in one direction at a time is called half duplex mode. E.g.: Wireless handset and walkie-talkie.

9. Full duplex mode [MF 2076] The transmission mode in which data can be transmitted in both directions simultaneously is called full duplex mode. E.g.: Telephone, internet etc.

10. Bandwidth [SEE 2066 S] Bandwidth can be defined as the maximum volume of data that can be transmitted through a communication system. We can measure bandwidth in digital devices by bits per second and in analogue devices by cycles per second or Hertz (Hz).

SEE COMPUTER SCIENCE 2076 Compiled by: Deepak Shrestha 11. Transmission medium / Communication Channel [SLC 2070 S] [SEE 2074 U] [MM 2076] [MFT 2075] Transmission medium is a pathway that can transmit information from a sender to a receiver through wired or wireless medium on a network. The types of communication medium are: i) Guided Medium (Bounded or Wired) ii) Unguided Medium (Unbounded or Wireless)

12. Guided medium [SEE 2074 U] The transmission media which comprises of cables or wires through which data is transmitted is called guided medium. They are called guided since they provide a physical channel from the sender device to the receiver device. The signal travelling through these media are bounded by the physical limits of the medium. E.g.: twisted pair cable, co-axial cable, fibre optics cable, etc.

13. Features of guided media: [SEE 2075] - Data transmits through the physical cable or fixed path - Data transmission rate is higher.

14. Unguided medium [SEE 2074 U] The transmission media which transfer data in the form of electromagnetic waves that do not require any cables for transmission is called unguided medium. These media are bounded by geographical boundaries. E.g.: radio wave, microwave, infrared etc.

15. Twisted pair cable A pair of wires twisted with each other is known as twisted pair cable. A set of four pairs of twisted wires are bundled to form cable. These are the most common medium for LAN. Wires are twisted with each other so as to reduce crosstalk (A disturbance caused by electromagnetic interference, along a circuit or a cable pair). Its types are: a) Unshielded Twisted Pair Cable b) Twisted Pair Cable

16. Unshielded twisted pair (UTP) Unshielded twisted pair is a popular type of cable that consists of two unshielded wires twisted around each other which are used in telephone wiring and local area networks (LANs). It is called unshielded because it has no additional foil wrap, or shield. RJ-45 connector is commonly used with unshielded twisted pair.

17. Shielded twisted pair (STP) Shielded twisted pair is a type of copper telephone wiring in which each of the two copper wires are twisted together and coated with an insulating coating. The extra covering in shielded twisted pair wiring protects the transmission line from electromagnetic interference. D-shell connectors are used with shielded twisted pair.

18. Co-axial cable Coaxial (or “coax”) cable is a common type of cable used for transmitting data over long distances. They are most commonly used to transmit cable TV and Internet signals. The connectors used with co-axial cables are BNC, T-connectors and terminators in bus topology. 10 Mbps is the maximum speed of co-axial cable.

SEE COMPUTER SCIENCE 2076 Compiled by: Deepak Shrestha 19. Fiber optic cable Fiber optics cable is one of the costlier cables used in data communication which uses light to carry a data signal through the cable. The connectors used in fiber optics are Screw Mounted Adaptors (SMA), Spring-loaded Twist (ST), SC and FC. It is costlier to maintain, produce and install.

20. Radio wave transmission The transmission making use of radio waves through air is called radio wave transmission. It provides low bandwidth for data communication. Radio, TV, cellular phones etc. uses radio transmission in one form or another. The radio waves can travel through walls and through an entire building. Depending upon the frequency, they can travel long distance or short distance. It does not require line of sight for data transmission 21. Microwave transmission Microwave is a line-of-sight wireless communication technology that uses high frequency beams of radio waves to provide high speed wireless connections that can send and receive voice, video, and data information. Microwaves do not pass through buildings. So, indoor receivers cannot be used effectively. It provides higher bandwidth for data communication. It requires line of sight for data transmission.

22. Infrared transmission Infrared Transmission is the transmission of data or voice information over infrared (IR) light over short ranges. It requires line-of-sight and is unable to break through walls.

23. Computer network [SLC 2066] [SLC 2068 S] [SLC 2069 S] [SLC 2070 S] [SLC 2071 S] [SEE 2074] [MF 2076] A computer network means two or more computers connected with each other to share data, hardware, software and other resources.

28. Goals of computer network a) Resource sharing and Reliability b) Communication medium c) Access to remote database d) Easy data transfer

29. Computer Network reduces expenses of an office. Justify this statement with an example. Computer Network reduces expenses of an office because computer on a network share different hardware devices like printers, scanners, hard disk etc. And sharing those hardware devices will reduces the expense of an office. For example if there are twenty computers in an office, now for printing the data there is no need to buy twenty printers individually rather than simple network the computer and connect the printer on the network which helps in sharing of the one printer among twenty computers which reduces the cost of buying nineteen printers individually.

30. Computer network makes the world a small place. Justify. Computer network makes the world small place. It is true because in computer network we can know about the events and things place outside or inside the country sitting within a room. And we also can communicate with our relatives who are far away from us or has gone to abroad for job or study. Therefore, computer network makes the world a small place.

SEE COMPUTER SCIENCE 2076 Compiled by: Deepak Shrestha 36. Network Interface Card (NIC) [SQE 2075K] A Network Interface Card (NIC) is the adapter through which the computer is connected to the network. The function of NIC is to convert data into electronic signals and transfer them through cables and vice-versa. The advantage is to present the platform for a communication between the computers within a network.

37. Cable Cables are commonly used media of physical channel for transmitting data between computers in network. Examples of cables are coaxial, twisted pair and fiber optic cable.

38. Connector Connector is an interface between the NIC of the computer and the cable that passes data between computers in network. Examples of connectors are BNC used with coaxial cable, RJ 45 used with UTP cable, ST used with fiber optic cable etc.

39. Hub [MF 2076] A hub is a network device with multiple points or ports which acts as a central point from where different computers and other devices are connected. It broadcasts all network data across each connection. Hub is mostly used in physical star topology.

40. Switch [MF 2076] A switch is a networking device that has multiple connecting ports which is often used interchangeably with the bridge.

41. Bridge A bridge is a device that connects two or more similar types of network which filters the data or inspects incoming signals and decides whether to forward the signals or discard them.

42. Gateway Gateway is an interconnecting device that connects two dissimilar networks

43. Repeater Repeater is a device that amplifies the incoming signals, creates a copy of it and transmits the signal on network.

44. MODEM [MFT 2075] MODEM is a device which is used to transfer the data of one computer to another computer using telephone lines. The role of MODEM in data transmission is that it transfers data from one computer to another through telephone line. It also converts the digital signal into analog and vice versa.

45. Importance of MODEM [SLC 2064] [SLC 2071 S] [SEE 2073 U] MODEM modulates the digital codes of the computer into analog signal, which then can travel through the telephone cable. At the receiving end the MODEM kept there will demodulate the analog signal to digital codes, which can be then understood and used by the receiving computer. In this way a MODEM makes the computer network possible.

46. Modulation The process of translating digital signals of a computer to analog signals, which are then transmitted across the standard telephone lines, is known as modulation.

52. LAN (Local Area Network) A LAN is a type of network which covers small area i.e. within a room, building, or short distance by using cables or small wireless devices. It is controlled by a single organization. It uses private connection media. E.g.: network in a school, college or cyber cafe. The diameter is not more than a few kilometres. LAN offers bandwidth of 10- 100 Mbps.

53. MAN (Metropolitan Area Network) A MAN is a type of network which covers an entire city. It is controlled by single or group of organization. It uses private or public connection media. E.g.: interconnection between different branches on same branch and ISP providing internet services. It offers a number of network services compatible with bandwidth from 128 kbps to 1 Gbps.

54. WAN (Wide Area Network) A WAN is a type of network which connects two or more computers generally across a wide geographical area such as cities, districts, and countries. It is controlled by group of organization. It uses public connections media like telephone lines, satellite links or microwave system to connect several LANs and MANs. E.g. internet. Data transmission in WAN is slower than LANs and WANs.

55. Network topology (LAN topology) [SLC 2064] [SLC 2065 S] [SEE 2066 S] [SEE 2067 S] [SLC 2068] [SLC 2070] [SEE 2072] [SEE 2075U] The arrangement or connection pattern of computers or nodes and other devices of the network is called network topology.

66. Advantages of star topology i) Easy to set up and configure. ii) Failure of single computer or cable doesn’t affect the entire network. iii) It is easy to find the fault. iv) It is easy to extend to network by attaching new devices to the central devices. Disadvantages of star topology i) It requires more cable in comparison of bus topology so it is more costly. ii) Failure of central devices (hub or switch) break down the whole system. 67. Network architecture (Models of Computer Network) The arrangement of the computers on the network which is based on the computing model is called network architecture. Its types are a) Centralized computing network b) Client / Server Network c) Peer to Peer Network 68. Centralized computing network [SQE 2074K] A centralized computing network is a network in which a central host computer performs data processing and storage on behalf of clients. It is different from client server network as client server network consists of at least one server and one or more client as well as client server provides high security of data and other resources. 69. Client/server network [SLC 2071] Client/ server network is a type of network architecture that consists of at least one server and one or more clients or workstations, where users do their work. It provides central security administration and the network administrator is responsible for data security and other resources management of the network. 70. Peer-to-peer network [SLC 2071] Peer-to-Peer network is a group of computers, which function both as servers and workstations to share data, information and other resources of the network. It lacks centralized network administration, where the network administrator needs to manage security on each computer. It provides no reliable security and might put data in higher risks.

SEE COMPUTER SCIENCE 2076 Compiled by: Deepak Shrestha Modular Programming Questions and Answers [25] 1. Modular programming [SEE 2075 U] [SLC 2066] [SEE 2065 S] [MM 2076] [PMT 2075K] Modular programming is a technique used to divide program into many small, manageable, logical and functional modules or blocks.

2. Qbasic is called Modular Programming [MFT 2075] [SQE 2074K] QBasic is called modular programming because it divides program into many small, manageable, logical and functional modules or blocks.

3. Advantages of modular programming [SEE 2073 U] [MFT 2075] [SQE 2074K] i) Different programmers can design different program modules independently, which is required in a large and complex program. ii) It is easy to design code and test the program modules independently. iii) It is possible to use a single module in different places which reduces program codes. 4. Main module The top level controlling section or the entry point in modular programming is called main module.

5. Sub module Module is a block of statement that solves a particular problem. Sub module is a program which is written under the main module. A program may have one or more sub modules under main module.

6. Procedure [SLC 2072] [SLC 2071] [SLC 2064] [SLC 2067] [SLC 2068 S] [SQE 2075K] [PMT 2075K] Procedure is a block of statements that solves a particular program. Procedure is a section of code which performs one or more specific tasks and can be accessed from remote location. There are two types of procedure – SUB Procedure and FUNCTION procedure

7. SUB procedure [SLC 2064] [SLC 2065] [SLC 2069 S] [MM 2076] A SUB procedure is a small, logical and manageable functional part of program which prefers specific task and does not return any value. SUB-procedure is called by CALL statement. SUB-procedure’s name does not accept data type symbol because it does not need to return a value.

8. FUNCTION procedure [SLC 2064] [SLC 2065] [SLC 2069 S] [MM 2076] A FUNCTION procedure is a small, logical and manageable functional part of a program which performs specific task and returns single value to the main program or calling module. FUNCTION-procedure is called by statement and expression method. FUNCTION-procedure’s name accepts data type symbols such as $, %, !, #, &, etc. and it depends on the type of value to be returned. E.g.: FUNCTION REV$ returns string.

9. String function [SEE 2074 U] String function is used with string it returns string value.

10. Numeric function [SEE 2074 U] Numeric function is used with number it returns numeric value.

11. Library functions [SQE 2074K] Library functions are built-in or readymade functions provided by QBASIC. E.g. MID$( ), LEN( ), SQR( ) etc.

12. User defined function [SLC 2066 S] [SQE 2074K] Function which is defined by the user according to the need is called user defined function. https://seeqbasicomputer.blogspot.com/ 68 | P a g e

SEE COMPUTER SCIENCE 2076 Compiled by: Deepak Shrestha 13. Parameters [SEE 2074] Parameters are variables that will receive data (arguments value) sent to the procedures (SUB program and FUNCTION). Formal parameters are called parameter. 14. Arguments Arguments are the values that are sent to the procedures (SUB program and FUNCTION). Actual or real parameters are called arguments. 15. CALL statement [SLC 2071] [PMT 2075K] The function of CALL statement is to transfer the control to another procedure. 16. DECLARE statement The function of DECLARE statement is to declare procedure such as FUNCTION or SUB in modular programming. 17. DIM SHARED statement i) It makes variable accessible to all modules. ii) It appears in main module/ program. 18. SHARED [SLC 2071] It is used in the sub program to share the values of certain variables between main module and sub program 19. COMMON SHARED [SEE 2074 U] It is used in the main program to share variable list between main module and all sub programs. This statement is used to declared variable global. 20. Local Variable [SEE 2075 S2] Variables which are declared inside the procedure are called local variables. Local variables are not visible to other modules or functions. Its value is protected from outside interference and has no effect on the variables outside the procedures. Local variable can access only in its own module. 21. Global Variable [SEE 2075 S2] Variables which are declared outside the procedure are called global variables. Global variables are visible to other modules or functions. Its values can be accessed from any procedure or module. Global variable can be access throughout the program 22. Passing arguments by value When arguments are passed by value it makes a duplicate copy of arguments and their values (constants) are used directly in parameter. It doesn’t make any effect on values of variable which are passed to a procedure even they are changed in the procedure. To pass the argument by value, variable is enclosed in parenthesis.

23. Passing arguments by reference When arguments are passed by reference the address of the variables are passed to the procedure. The changes made in the procedure’s variable will affect the variables used at calling module. By default the value is passed by reference.

24. Qbasic Operators [MFT 2075] [SQE 2074K] Operators are special symbols that are meant for specific tasks or operators. i) Arithmetic operators ii) Relational operators iii) Logical Operators iv) String operator

25. Static variable The variable which is declared by using the “STATIC” keyword is called static variable.

SEE COMPUTER SCIENCE 2076 Compiled by: Deepak Shrestha Handling of data file Questions and Answers [25] 1. Data file The file which contains data given by the user to the program and information provided by the user to the computer is called data file. The different types of data file are: a) Sequential Access files - A data file that stores a sequential data file containing name, address of some people in the same order or in sequential order is called sequential access data file. It takes long time to access if the data file contains a large volume of data. In sequential access data file we cannot change the existing entry or insert a new entry. b) Random access files 2. Program File The file which contains a set of instructions that are needed for data processing is called program file. 3. Mode of data file [SLC 2069] Mode of data file means opening a sequential file for one of the three modes of operation like output mode, input mode and append mode. 4. Modes of operation for opening a sequential file a) Output Mode: It is used to create a new data file and write data in it. If the file already exists its current contents will be destroyed. b) Input Mode: It is used to retrieve records or contents of existing data file. c) Append Mode: It is used to add more records in existing file. If the specified file does not exist APPEND mode creates it. 5. File number The number assigned to a file in order to identify it during processing is called file number. Write down the functions of: 6. OPEN statement: It opens a sequential file for one of the three possible operations (reading, writing, appending). 7. WRITE statement [SEE 2075] [MM 2076]: It sends one or more data items to the specified file. It inserts commas between the data items. It encloses strings in double quotation marks. 8. PRINT#: It adds spaces between data items while storing data. It does not enclose strings in double quotation marks. 9. CLOSE statement [SEE 2074] [SEE 2073: It closes one or all open files. 10. INPUT# statement [SEE 2075 U] [SEE 2075 S 2]: It reads data from the sequential data file. 11. EOF( ) function [SEE 2075 S 2]: It is used to test the end of records with in a file. 12. LINE INPUT statement: It reads the entire line or maximum 255 characters form the keyboard or the sequential file. 13. INPUT$ function: It reads the specified number of characters form the data file. 14. NAME statement [SEE 2073] [SLC 2071 S]: The NAME statement renames a file on a diskette. Only file name changes, data and program line remains intact. 15. KILL statement [SEE 2074]: The KILL statement deletes the file or files from the specified drive and directory. 16. MKDIR statement [SEE 2075 U]: It creates a subdirectory which is used to manage files. 17. CHDIR statement: It allows QBASIC to change from one directory to another. 18. RMDIR statement [SLC 2065] [SLC 2068 S]: It is used to remove or delete only the subdirectories from a disk. It can remove only empty subdirectories. 19. FILES statement: The FILES statement displays the files of the current sub directory or specified sub directory. 20. SHELL: The SHELL statement allows a program to run external programs or command line statements in Windows, MAC OS and Linux. 21. INT [MM 2076] [MFT 2075]: It rounds and returns the largest integer less than or equal to a numeric expression. 22. PRINT [PMT 2075K] : Display result on screen. 23. MID$ ( ) [MFT 2075]: It is a string function that returns the specified number of characters from the specified location of string. 24. LEN ( ) [SQE 2074K]: Returns the number of characters in a string or the number of bytes required to store a variable. 25. SQR ( ) [SQE 2074K]: Returns the square root of a numeric expression. https://seeqbasicomputer.blogspot.com/ 70 | P a g e

SEE COMPUTER SCIENCE 2076 Compiled by: Deepak Shrestha Introduction of C Questions and Answers [20]

1. Structured programming The programming that follows a top- down approach, on which developers separate the overall program structure into different sub selection, is called structured programming.

2. Advantages of structured programming [SEE 2075] [SLC 2066] a) It is easy to design code and test the program modules independently b) It is possible to use a single module in different in different places which reduces program codes.

3. C language C language is a structured programming language that divides program into many functions. Dennis Ritchie at Bell telephone laboratory developed C-language in 1972 AD. C is called middle level language because it combines elements of high level language with some features of assembler. A high level language tries to give programmer everything through built-in language. A low level language forces programmer to define function directly from user level. C is mostly used to write system program such as operating system, language, compiler, text editor, language interpreters, utilities, etc. C keywords are words which have special meaning for the compiler. Examples are: auto, break ,case, char etc.

4. Data types used in C Data type are means to identify the type data and associated operation of handling it.

5. Data types used in C language [SEE 2074] [SLC 2072] [SLC 2071 S] [SLC 2065] [SLC 2068] [SLC 2070] [SEE 2065 S] [SLC 2066 S] [SLC 2067 S] [SLC 2069 S] [SLC 2070 S] [SQE 2074K] a) char b) int c) float d) double

6. Data Modifiers: Data modifiers change the meaning of the basic data type to fit the various situations. The data modifiers are: short int, unsigned int and long int

7. Characteristics of C language [SEE 2075 U] [SEE 2075 S 2] [SLC 2071] [SLC 2067] [SLC 2069] a) It is a high level language with some features of low level language. b) It is mostly used to prepare system software. c) It is structured programming language with function procedure. d) It has enough number of inbuilt functions and operators. e) It is a small programming language which occupies less memory space.

8. Features of C- language [SEE 2073 U] a) Simple and easy to use b) Occupies less memory c) C is the structured programming language. d) C has powerful set of operators. e) C is a high level programming language. f) C contains very less number of keywords

It has poor errors detection system. b) On large programs , it is hard to find errors. c) There is no strict type checking int data type to float variables. d) It does not support modern programming methodologies oriented programming language.

11. Counter Counter is a variable which controls the loop statement and provides the track to run the loop statement in certain number times.

12. Accumulator Accumulator is a numeric variable which accumulates the values in a loop statement.

13. Variable [SEE 2073] [SLC 2071 S] [SLC 2070] [MFT 2075] A variable is a location in the memory of a computer whose value may change during the execution of program.

14. Constant Constant are the values that do not change during the execution of a program.

15. Operator [SQE 2075K] Operators are special symbols that are meant for specific tasks or operators. The different types of C operators are:- Arithmetic operators, Assignment operators, Unary operators, Relational operators, Logical operators and Conditional operators. Arithmetic operators are the operators that are used for manipulating arithmetic data and performs arithmetic operation. The arithmetic operators are:- +, - , * , / and % The operator that operate on one operand variable or constant is called urinary operator. E.g. ++, - -

16. Logical Operator [SEE 2075] The operators used for logical operation is called logical operator.

17. Selection statement. Selection statement is a statement that allows the selective execution o statements depending on the value of an an expression. The selection statements of C program are:- If statement and Switch statement

18. Loop [SEE 2073] [SLC 2068] [SLC 2067 S] [SLC 2070 S] A set of statements which is used to repeat a block of statements for a specific number of times or as long as the condition is true/false is called loop. The looping statements provided by care:-For loop, While loop and Do.....while loop

19. Comparing C and QBASIC language [SEE 2074 U] [SLC 2068 S] QBASIC C It is a high level language without feature of low It is a high level language with some features of level language. low level language. It is mostly used to design application software. It is mostly used to prepare system software. It supports structure programming with sub and It is a structured programming language with function procedure. function procedure. It is not case sensitive It is case sensitive IBM PC version of BASIC has around 159 It has only 32 keywords. keywords.
