TESTE DEIN WISSEN

What are the three classes of use of a computer?

Lösung anzeigen
TESTE DEIN WISSEN
  1. Personal Computers (PC): A computer designed for use by an individual, usually incorporating a graphics display, a keyboard, and a mouse.
  2. Servers:  A computer used for running larger programs for multiple users, oft en simultaneously, and typically accessed only via a network.
  3. Embedded Computers: A computer inside another device used for running one predetermined application or  collection  of software.

What are PMDs? What is it replacing?

Lösung anzeigen
TESTE DEIN WISSEN

Personal mobile devices (PMDs) are small wireless devices to connect to the Internet; they  rely  on  batteries for power, and soft ware  is installed by  downloading apps. Conventional examples are smart phones and tablets.

What was the constrain for programming back in the 60s-70s? What are the contrains currently?

Lösung anzeigen
TESTE DEIN WISSEN

Back then: In the 1960s and 1970s, a primary constraint on computer performance was the size of the computer’s memory. Th us, programmers oft en followed a simple credo: minimize memory space to make programs fast
Today: the parallel nature of processors and the hierarchical nature of memories. Today’s programmers need to worry about energy effi  ciency  of their programs, which also requires understanding what is below your code.

What is an OS? What are its three main functions?

Lösung anzeigen
TESTE DEIN WISSEN

An operating system is a supervising program that manages the resources of a computer for the benefit of the programs that run on that computer. 

  1. Handling basic input and output operations
  2. Allocating  storage and memory 
  3. Providing for protected sharing of the computer among multiple applications using it simultaneously.

What are LCDs?

Lösung anzeigen
TESTE DEIN WISSEN

Liquid crystal display: a display technology using a thin layer of liquid polymers that can be used to transmit or block light according to whether a charge is applied.

What is the function od the datapath and the control inside the processor?

Lösung anzeigen
TESTE DEIN WISSEN

The datapath performs the arithmetic operations, and the control tells the datapath, memory, and I/O devices what to do according to the wishes of the instructions of the program.

What is DRAM? What does RAM mean?

Lösung anzeigen
TESTE DEIN WISSEN

Dynamic random access memory (DRAM): Memory built as an integrated circuit; it provides random access to any location. Access times are 50 nanoseconds

The RAM  portion of  the term  DRAM means that  memory accesses take basically the same amount of time no matter what portion of the memory  is read.
