Understanding Network Topology
Topology determines the physical configuration of a network. Basically it provides the way how to connect computer while developing computer network. There are number of topology available, such as bus topology, star topology, ring topology, tree topology and hybrid topology.
Star Topology
Star Topology is one of the most common network setup. In this topology each node is directly connected with hub. Thus the devices in the network are not directly linked to each other. The main advantage of star topology is that if any node fails, it does not affect the entire network. It is also less expensive than mesh, and hence easy to configure and maintain. The main disadvantage of star topology is that if the central hub fails, all computers connected with hub are disconnected automatically and whole network would fail. The following is the figure of star topology: (See Figure. 9.4.4)
Bus Topology
Bus Topology provides one of the simplest network structures. In this topology all nodes are connected together to the parallel cable by drop lines and taps / T- connectors. The cable is arranged in a straight line and each node connects to the cable with a T-connector. The advantage of bus topology is low cost because it requires less cable, It is also easy to install. It is difficult to reconfigure. It has parallel network cable. The major disadvantage of this type of topology is if cable breaks, then entire network fails down. The following is the figure of bus topology: (See Figure. 9.4.5)
Ring Topology
In Ring Topology all computers are connected in a ring shape. In this topology each node has an input and an output connection. It contains wiring that allows information to pass from one device to another in a circle or ring. The main advantages of ring topology is, it is easy to install and provides good signal quality. The main disadvantages of ring topology: If one node fails or the ring is broken, then the network is down. The following is the figure of ring topology: (See Figure. 9.4.6)
Topology determines the physical configuration of a network. Which one of the following is not a network topology?
(A) Star
(B) Bus
(C) Ring

In which of the following topologies each computer is directly attached with hub?
(A) Bus
(B) more... 
Types of Network
While connecting more than one computer with each other through wire or wireless is called computer network. The first network was implemented by both IBM's SNA (Systems Network Architecture) and Digital's network architecture. Using network you can share peripheral and software. You need to load software only on the file server. All interconnected users use these software form server. This technique saves time and cost compared to installing and tracking files on independent computers. Using network you can also share several resources and files, such as printers, scanners, fax machines and modems which reduces the cost of hardware.
There are three types of computer network. They are the following:
LAN (Local Area Network)
A local area network can be of two computers and a printer in office, home or it can be extended throughout an organization. A computer lab in a school or college is a good example of LAN. It enables multiple users in a relatively small geographical area to exchange files and messages, as well as access shared resources such as file servers and printers. (See Figure. 9.4.1)
The following figure shows a LAN structure
WAN (Wide Area Network)
A Wide Area Network is one of the computer networks which is established on a large geographical area. While accessing through the Internet and connecting to the locations of an organization to each other it uses data links provided by the carrier services. It generally carries a variety of traffic types such as data, video and voice. Data services and telephone services are the most commonly used services. Today, high-speed LANs and switched internet works are becoming widely used, largely because they operate at very high speeds and support such high-bandwidth applications, as multimedia and video conferencing. The following image shows a WAN: (See Figure, 9.4.2), Internet is the best example of WAN. It allows people to access a vast information resource, talk to each other by email and join electronic news, discussion and special mailing groups.
The Fallowing are the advantages of the Internet:
Mnemonic
Mnemonic word
comes from the Greek mnemonikos which refers to the mind. Basically it is a
special word that is used to help a person remember some thing. Many mnemonics
also take the form of acronyms. Basically mnemonics are verbal, such as a very
short poem or a special word.
Compiler
vs. Linker
Linker is a
program that combines the one or more object which is generated by compiler
into a single executable program. They are also useful to convert object code
into executable code. Compiler is system software that executes the computer
program and converts it into machine language. It also debugs syntax error and
run time error.
Compiler
vs. Interpreter
Compiler is system
software that executes the computer program and converts it into machine
language. Compilers are widely used in translating code of high-level
languages, such as C. It provides faster execution speed. Interpreter is a type
of translator that translates the program line by line. It is very slow for
executing large programs. Hence, interpreters are not suitable for most of the
applications development.
Generation
of Languages
First
Generation Languages (1 GL)
Basically first
generation languages are low level languages that consists machine language.
This language is directly processed by microprocessor. There is no need to any
translator.
Second
Generation Languages (2 GL)
It is also a low
level language that consists of assembly language. This language is not
directly processed by microprocessor. A translator namely Assembler converts it
into machine language. That machine code is directly understood by
microprocessor.
Third
Generation Language (3GL)
Basically third
generation languages are high level language. It is a type of advanced computer
programming language, such as FORTRAN, C, Prolog and PASCAL. They support OOP
concept and helps in development of large programs.
Fourth
Generation Language (4GL)
These kinds of
languages are easy to write computer program. They are similar to English
language statements. This kind of languages is used in data base programming
and scripts. ABAP, SAS, Visual FoxPro and Uniface are the some well known
languages that are categorized in 4GL.
Fifth
Generation Language (5GL)
Visual Basic is
the best example of fifth generation languages SG- such as Mercury is mainly
used in aircraft intelligence research.
Mnemonic

Incorrect Options:
Rest of the options is incorrect. 
Assembly language
The assembly language is also called 2GL. This language is not directly processed by microprocessor. A translator namely Assembler converts it into machine language. That machine code is directly understood by microprocessor A translator namely are close to a one to one correspondence between symbolic instructor's instructions and machine code Writing program in assembly language is typical than writing program in high level language because program needs to have detail knowledge of the processor.
Main features of assembly languages are the following:
Machine Language
Machine language is the lowest level computer language that is directly understood by a program. The machine language is also called 1GL. This language is directly processed by microprocessor. There is no need to any translator. Machine language is sometime called native code. Writing program in machine language is very typical task. You can lot write program in machine language directly. Machine language is created by programs called assemblers, interpreter and compiler.
Assemblers
Assemblers translate the assembly language code (source program) into machine language code (object program), after assembling; a linker program is used to convert the object program into an executable program. The MASM (Microsoft Assembler Program) and Borland TASM (Turbo Assembler Program) are two popular assemblers. Assemblers are used mainly in development of system software.
Interpreters
Instructions of a high-level language are coded in many statements. At the time of their execution, they are converted statement by statement into machine code, by using system software, called Interpreters. For example, programs written in BASIC language are executed by using BASICA or GWBASIC interpreters. There are certain disadvantages of interpreters. As instructions are translated and executed simultaneously using interpreters. They are very slow for executing large programs. Hence, interpreters are not suitable for most of the applications development.
Compilers
Is system software that provides faster execution speed. Compilers do not translate and execute the instructions at the same time. They translate the entire program into machine code. Compilers are widely used in translating code of high-level languages, such as COBOL, FORTRAN, PASCAL, Turbo/ Quick BASIC, Turbo/ Microsoft C, Java, etc. Mostly compilers are preferred in development of application software. Compilers are not only working as a translator they also debug syntax error and compile time error. 
Time Sharing Operating Systems
In time sharing system multiple jobs are executed by switching the CPU between them and the CPU time is shared by different processes. In this environment various users are sharing the central processor, the memory and other resources of the computer system in a manner facilitated, controlled and monitored by the operating system. UNIX is the best example of time sharing operating system.
