Q-1) Which of the following memory chip is programmed during the manufacturing process?
(a)
(b)
(c)
(d)
Read-only memory (ROM) is a class of storage medium used in computers and other electronic devices. It is programmed during manufacturing process.
Q-2) ______is cross between human language and a programming language.
(a)
(b)
(c)
(d)
Pseudocode is an informal high-level description of the operating principle of a computer program or other algorithm. It uses the structural conventions of a programming language, but is intended for human reading rather than machine reading.
Q-3) Which among the following standard protocols is the most widely used by the Internet ?
(a)
(b)
(c)
(d)
The Internet protocol suite is the set of communications protocols used for the Internet and similar networks, and generally the most popular protocol stack for wide area networks.
It is commonly known as TCP/IP, because of its most important protocols: Transmission Control Protocol (TCP) and Internet Protocol (IP), which were the first networking protocols defined in this standard.
Q-4) One kilobit is equal to_______ bits
(a)
(b)
(c)
(d)
The kilobit is a multiple of the unit bit for digital information or computer storage.
The prefix kilo (symbol k) is defined in the International System of Units (SI) as a multiplier of 103 (1 thousand), and therefore, 1 kilobit = 103 bits = 1000bits.
However, computers are binary or base 2, as in ones and zeros. So instead of counting by tens, they count by 2s.
So instead of 1, 10, 100, 1000 it is 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024.
Q-5) A __________ is an agreement between the communicating parties on how communication is to proceed.
(a)
(b)
(c)
(d)
In information technology, a protocol is an agreement between the communicating parties on how communication is to proceed.
Violating the protocol makes communication more difficult, if not impossible. A protocol is the specialist set of rules that endpoints in a telecommunication connection.
Q-6) Which type of switching is used in Internet?
(a)
(b)
(c)
(d)
Packet switching is the dividing of messages into packets before they are sent, transmitting each packet individually, and then reassembling them into the original message once all of them have arrived at the intended destination.
Packets are the fundamental unit of information transport on the internet that uses the datagram packet switching method. Most modern Wide Area Network protocols, including TCP/IP, are based on packet-switching technologies.
Q-7) Data in database at a particular point of time is called as:
(a)
(b)
(c)
(d)
The overall design or description of the database is known as database schema or intension of the database and is specified while designing the database.
The data in the database at a particular point of time is known as database instance of database state or snapshot. The database state is also called an extension of the schema.
Q-8) A collection of pictures that can be inserted into documents is called :
(a)
(b)
(c)
(d)
Clip art, in the graphic arts, refers to pre-made images used to illustrate any medium.
Today, clip art is used extensively in both personal and commercial projects, ranging from home-printed greeting cards to commercial candles. Clip art comes in many forms, both electronic and printed.
However, most clip art today is created, distributed, and used in an electronic form.
Q-9) _______ allows users to access accounts and pay bills
(a)
(b)
(c)
(d)
Electronic commerce, commonly known as e-commerce, is the buying and selling of products or services over electronic systems such as the Internet and other computer networks.
Electronic commerce draws on such technologies as electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems.
Q-10) Which of the following circuit is used as 'Memory device' in computers ?
(a)
(b)
(c)
(d)
A flip-flop is a circuit that has two stable states and can be used to store state information. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs.
It is the basic storage element in sequential logic. Flip-flops and latches are a fundamental building block of digital electronics systems used in computers, communications, and many other types of systems.
