What is MAN

NIELIT O Level Solved Paper

Internet and Web Technology

Q: Define MAN. Write down three important features that discriminate MAN from WAN.

A metropolitan area network (MAN) is a network that connect users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.

What is Topology

Nielit O Level Solved Paper

Internet and Web Design

Q: Explain in brief: Bus, Star and Ring Network Topologies

Physical and logical arrangement of devices with a network is known as Topology.

Bus Topology

A bus topology is a network setup in which each computer and network device are connected to a single cable or backbone.A signal from the source is broadcasted and it travels to all workstations connected to bus cable. Although the message is broadcasted but only the intended recipient, whose MAC address or IP address matches, accepts it. If the MAC /IP address of machine doesn’t match with the intended address, machine discards the signal.

Describe the ISDN

Q 5 (a). Describe the ISDN ?

Integrated Services Digital Network (ISDN)

Integrated Services Digital Network (ISDN) is a telephone system network. It is a wide area network which is widely available. Before to the ISDN, the telephone system was viewed as a way to transport only voice, with some special services available for data. The key feature of the ISDN is that it integrates speech and data on the same lines, adding features that were not available in the classic telephone system.

Database relationship

Microsoft Access is an example of relational database. In relational data base we can join a table to more than one table which makes relationship. With this capability our access database becomes more powerful than non-relational data base category. Consistency of database become easy and easily achieve by database on automatically.  If you want to make relationship in access database then you need at least two tables and one field must be common in both tables. For example, we are going to make relationship between two tables’ student and canteen. Student table store record of student and canteen stores what the products students are having. So in this type of relationship student is master table and canteen is related table. So student table need a primary key which uniquely identified a record from student table. Canteen table must have a key which match the data type of student table primary key which further known as foreign key.

The following is a partial taxonomy of rotating electrical machines. Electrical machines may

be categorized for analysis purposes into alternating current (ac) or direct current (dc).

Some machines run on ac, some on dc, and some will run on either. An ac machine may

be synchronous or induction. A few examples of electrical machines include large

synchronous motors, small induction motors, universal motors, and permanent magnet

motors. Most motors found in the homes are usually induction machines or universal

motors. Universal motors are typically used in where high speed is needed such as in

blenders or vacuum cleaners. They will run on either “AC” or “DC”. Permanent magnet

motors are frequently used in toys and will work only on dc.

Girfa Library Management is window based software written in VB.Net. This software covers all working aspect of a library. You can use this software at any school, college or any book shop that run their own paid library. Due to flexible of this software, which achieve all the activity of library Management task in an efficient way. The simplicity of the software need little bit training for execution. Power of software is wide range of report generation which makes audit work easy. Various types of setting option in option menu like book issue day, fine amount and many more makes this software dynamic.

Polymorphism

“One name many form.”

Polymorphism gives the ability to dynamic programming to a language which reduces to write repeated code for each module. You can use polymorphism for flexible programming for example if you‘re making software for a school and you need to print record of different type person which may be student, teacher, non teaching staff etc. So without using polymorphism you need to make separate function for each person related record printing. which lead to increase complexity. In polymorphism you need to make a function for printing record and rewrite different version of this as printing which are isolated by function signature. So you have a better approach to solve your need with flexible coding.
