Microsoft Office is an example of a

  1. closed-source software

  2. open-source software

  3. horizontal-market software

  4. vertical-market software

  5. compiler
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Microsoft Office is an example of a closed-source software.

Closed source (or proprietary software) means computer programs whose source code is not published. The source code is not shared with the public for anyone to look at or change. Closed source is not open source, but some software is neither, because open source also implies the freedom to redistribute.

Examples of closed source software for commercial use are Microsoft Office, Adobe Acrobat, McAfee anti-virus software, and so on. Examples of closed source software not distributed commercially would be proprietary software used to operate a proprietary operation at a bank or a factory.

Multiple choice elements of accounts using computerised accounting system grouping and codification of accounting steps in installation of cas accounting information system

One key control in the organization of the information systems department is the:

  1. Separation of the systems development group and the operations (data processing) group.

  2. Operating personnel should strictly control access to the client's database.

  3. Controller should manage the information system since it supplements the accounting work already done under the supervision of the controller.

  4. Information system department should be under the direction of systems development personnel since they are responsible for the overall performance of the system.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Separation of duties is a fundamental internal control principle in information systems. By separating the development group from the operations group, the organization prevents unauthorized changes to production systems and reduces fraud risk.

A.................... is a computerized centre, that is responsible for connecting calls, recording call information and billing. 

  1. Base station

  2. Mobile switching centre

  3. Cell

  4. Mobile station
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A  Mobile switching centre is a computerized centre, that is responsible for connecting calls, recording call information and billing.

A mobile switching center (MSC) is the centerpiece of a network switching subsystem (NSS). The MSC is mostly associated with communications switching functions, such as call set-up, release, and routing. The Mobile Switching Centre (MSC) is a telephone exchange that makes the connection between mobile users within the network, from mobile users to the public switched telephone network and from mobile users to other mobile networks.

BSC. The Base Station Controller (BSC) is in control of and supervises a number of Base Transceiver Stations (BTS). The BSC is responsible for the allocation of radio resources to a mobile call and for the handovers that are made between base stations under his control. Other handovers are under control of the MSC.

Base Transciever Station (BTS) The BTS is a telecoms infrastructure used to facilitate wireless communication between subscriber device and telecoms operator network. The subscriber device can be mobile phone, wireless internet devices while the operator network could be a GSM, CDMA or TDMA platform.

What is the name of the 64-bit Microprocessor developed by AMD?

  1. Opteron

  2. Risc-9000

  3. iMac

  4. Athlon
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Opteron is the name of the 64-bit Microprocessor developed by AMD.

Opteron is family of 64-bit x86 server uniprocessors and multiprocessors designed by AMD as a successor to the Athlon MP family. Opteron processors are designed for workstations and servers and are a direct competition to Intel's Xeon processors.

Opteron is the name of a family of CPUs within the AMD64 line. Designed by AMD for the server market, it competes with Intel's Xeon. For Socket 940 and Socket 939 Opterons, each chip has a three-digit model number, in the form Opteron XYY.

Opteron is AMD's x86 former server and workstation processor line, and was the first processor which supported the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003, with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed Barcelona) were announced on September 10, 2007, featuring a new quad-core configuration.

AMD's main products include microprocessors, motherboard chipsets, embedded processors and graphics processors for servers, workstations and personal computers, and embedded systems applications. AMD is the second-largest supplier and only significant rival to Intel in the market for x86-based microprocessors.

Multiple choice classification of computer introduction to the information age physics

A computer will function only if it.

  1. Has a control unit

  2. Is given input data

  3. Has a program in its memory

  4. Has software package

  5. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A computer will function only if  has a program in its memory.

The chips that make up a computer's internal memory come in two broad flavors known as RAM (random access memory) and ROM (read-only memory). RAM chips remember things only while a computer is powered on, so they're used for storing whatever a computer is working on in the very short term.

Organizing Data Storage. Data is stored as lots of binary numbers, by magnetism, electronics or optics. ... The computer's BIOS contains simple instructions, stored as data in electronic memory, to move data in and out of different storage locations and around the computer for processing.
