| Answer : Option B |
| Explanation : |
| ROM stands for Read-Only Memory. It is computer memory on which data has been prerecorded. Once data has been written onto a ROM chip, it cannot be removed and can only be read. Unlike main memory (RAM), ROM retains its contents even when the computer is turned off. ROM is referred to as being nonvolatile, whereas RAM is volatile. |
17. Which of the following are advantages of CD-ROM as a storage media?
| Answer : Option A |
| Explanation : |
| CD-ROM is a circular disk used to store large amounts of electronic data. CD-ROMS can hold up to 680 MB of computer data. The media is low cost and durable, and in large scale applications can be inexpensively duplicated into thousands of copies. Unlike optical disks which can be written to many times, a CD-ROM is read only. |
18. After a user has saved and deleted many files, many scattered areas of stored data remain that are too small to be used efficiency, causing
| Answer : Option E |
| Explanation : |
| Fragmentation occurs when a process which are loaded or removed from memory. The free memory space is broken into little pieces, such type of pieces may or may not be of any use to be allocated individually to any process. This may give rise to memory wastage or fragmentation. So, it is a phenomenon in which storage space is used inefficiently, reducingcapacity & often performance. |
19. What do we call for the arrangement when two or more computers physically connected by cables to share information orhardware ?
| Answer : Option D |
| Explanation : |
| When two or more computers are connected with one another for the purpose of communicating data electronically, it is called a network. In computer networks, networked computing devices pass data to each other along network links (data connections). The bestknown computer network is the Internet. |
20. A MODEM is connected in between a telephone line and a____
| Answer : Option B |
| Explanation : |
| Modem is an electronic device that allows computer to communicate over telephone wires or cable TV cable. One computer's modem converts its digital signals into analog signals and the othercomputer's modem reconverts the analog signals into digital signals. |
21. What is the full form of ROM ?
| Answer : Option E |
| Explanation : |
| ROM stands for read only memory. It is a computer memory that can permanently store data and applications within it. That is, it is non-volatile. |
22. What is the full form of VoIP?
| Answer : Option C |
| Explanation : |
| VoIP stands for Voice over Internet Protocol. It is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. VoIP services convert voice into a digital signal that travels over the Internet. |
23. The sequence of events that occurs in the computer when it is interpreting and executing an instruction is known as a (n)
| Answer : Option A |
| Explanation : |
| When a computer obeys the instructions in a computer program it is said to be running or executing the program. Before a computer can execute a computer program, the program must be resident in memory. Once the program is loaded into memory then the following sequence is carried out: Set instructions address to the address of the first instruction. While program not finished { Fetch instruction from current instruction address. Update current instruction address, execute the fetch instruction. } This sequence is called the execution cycle. |
24. Codes consisting of bars or lines of varying widths or lengths that are computer-readable are known as-
| Answer : Option C |
| Explanation : |
| Bar code is a series of parallel vertical lines (bards and space) that can be read by bar code scanners. It is used world wide as part of product packages, as price tags, carton labels, on invoices even in credit card bills. It facilitates unique product identifications through using international symboligies/ numbering systems promotes brand image and would enabletimely and accurate capture of product information. |
25. The __ of a system includes the programs or instructions.
| Answer : Option E |
| Explanation : |
| A computer software or a program is a set of computerised instructions that operate a computer, manipulate the data and execute particular functions or tasks. Computer software tells the hardware of a computer what to do. |
26. Which of the following computer languages is a mathematically oriented languages used for scientific problems?
| Answer : Option E |
| Explanation : |
| FORTRAN (Formula Translation) is a third- generation programming language that was designed for use by engineers, Mathematicians and other users and creators of scientific algorithms. |
27. The user generally applies ____ to access mainframe or super computer.
| Answer : Option E |
| Explanation : |
| Traditionally, user connect to a mainframe using a terminal which allowed them to input request to the mainframe. The mainframe would then handle all the computing before outputing a response. These terminals are called dumb terminals because they had no data-processing abilities of their own, they were simply windows through which users could access the mainframe. These days, terminal emulation software such as 3270 emulation is used in place of a terminal. |
28. _____ is the process of finding errors in software code.
| Answer : Option E |
| Explanation : |
| Debugging is the process of detecting and rectifying bugs in a software code that can cause it to crash, behave erratically or be susceptible to hacker or cracker attack. Bugs can be in a variety of forms : coding errors, design errors, complex interaction, poor user interface design and system failures. |
29. A directory within a directory is called
| Answer : Option B |
| Explanation : |
| A subdirectory is a directory within another directory or a folder within a ALL directories can become a subdirectory except for the master directory, which is typically referred to as the root directory or the parent directory. |
30. What is output ?
| Answer : Option D |
