Show answer
Correct Option: A
Explanation:

The function of a computer server is to store, retrieve and send computer files and data to other computers on a network.

For example, a user may set up a server to control access to a network, send/receive e-mail, manage print jobs, or host a website. 
Some server types- Web Server, Mail Server, etc.

Multiprocessor is a computer system _________________.

classification of computer introduction to the information age physics

  1. Where many CPU under a common control

  2. Consisting of more than one input devices under common control

  3. Where many output devices under common control

  4. All of the above

  5. None of these

Show answer
Correct Option: A
Explanation:

Multiprocessor is a computer system Where many CPU under a common control.

Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined (multiple cores on one die, multiple dies in one package, multiple packages in one system unit, etc.).

According to some on-line dictionaries, a multiprocessor is a computer system having two or more processing units (multiple processors) each sharing main memory and peripherals, in order to simultaneously process programs.[3][4] A 2009 textbook defined multiprocessor system similarly, but noting that the processors may share "some or all of the system’s memory and I/O facilities"; it also gave tightly coupled system as a synonymous term.

multiprocessor is a computer system with two or more central processing units (CPUs), with each one sharing the common main memory as well as the peripherals. This helps in simultaneous processing of programs.The key objective of using a multiprocessor is to boost the system’s execution speed, with other objectives being fault tolerance and application matching.

Apple Macintoshes(Macs) and PCs use different __________ to process data and different operating systems.

  1. Languages

  2. Methods

  3. CPUs

  4. Storage devices

Show answer
Correct Option: C
Explanation:

Apple Macintoshes(Macs) and PCs use different CPUs to process data and different operating systems

Macintosh and Windows are two different computer systems, and they run on different operating systems. A Mac computer runs on a Unix-based operating system that is designed and sold by Apple. The operating system being used currently for Macs is Mac OS X, and it is designed around graphic interface. The Windows-based computers operate on different operating systems which are made by Microsoft, and some of these are: Windows XP, Windows Vista and Windows 7. These Windows-based operating systems can be used on a variety of PCs which are widely used.

In functional composition, what is done with data flow diagrams _____________.

classification of computer introduction to the information age physics

  1. Is ignored

  2. Is portioned according to the "closeness" of data grams and data storage s items

  3. Is partitioned according to the logical "closeness" of the actigrams

  4. Bother a and c

Show answer
Correct Option: D
Explanation:

In functional composition, what is done with data flow diagrams Is ignored and partitioned according to the logical "closeness" of the actigrams.

Flow diagrams in general are usually designed using simple symbols such as a rectangle, an oval or a circle depicting a processes, data stored or an external entity, and arrows are generally used to depict the data flow from one step to another. A DFD usually comprises of four components.

A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system, modelling its process aspects. A DFD is often used as a preliminary step to create an overview of the system without going into great detail, which can later be elaborated.

A context diagram is a top level (also known as "Level 0") data flow diagram. It only contains one process node ("Process 0") that generalizes the function of the entire system in relationship to external entities. DFD Layers. Draw data flow diagrams can be made in several nested layers.

Which of the following functions are not performed by servers?

classification of computer introduction to the information age physics

  1. Email processing

  2. Database sharing

  3. Processing Web sites

  4. Storage

  5. Word processing

Show answer
Correct Option: E
Explanation:

Word processing is not performed by servers.

Word processors set up and prepare reports, letters, mailing labels, and other materials on a computer using a keyboard and word processing software. Word processors also often perform other clerical duties around an office such as copying documents and answering telephones.

Servers are computers that provide resources to other computers connected to a _________.

classification of computer introduction to the information age physics

  1. Mainframe

  2. Network

  3. Supercomputer

  4. Client

  5. None of these

Show answer
Correct Option: B
Explanation:

Servers are computers that provide resources to other computers connected to a Network.

A network server is a computer system, which is used as the central repository of data and various programs that are shared by users in a network. If you have a computer that you're no longer using due to its slow speed, you can turn it into a network server for other computers in your household.

In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients". This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices.
