Answer:                      

Explanation:

The hard drive is long-term storage, which means the data is still saved even if you turn the computer off or unplug it. When you run a program or open a file, the computer copies some of the data from the hard drive onto the RAM. When you save a file, the data is copied back to the hard drive.

Consider an error-free 64 kbps satellite channel used to send 512 byte data frames in one direction, with very short acknowledge
Vladimir [108]

Answer:

The answer is "2".

Explanation:

In the given question some information is missing, that is "The propagation time for satellite to earth" which is "270 milliseconds" so, the description to this question can be defined as follows:

Given values:

Bandwidth = 64 kbps

Data frames = 512 bytes  

Propagation Time (t​​​​​​p ) =270 ms

Change Bandwidth  kbps to bps:

1 kb= 1024 bytes

calculated bandwidth= 64 kbps = 64×1024 bps = 65536 bps

1 bytes = 8 bits

512 bytes = 512 × 8 =  4096 bits

Frame length = 4096 bits

Formula

Transmission time (T​​​​​​t) = Frame length /Bandwidth

Window size = 1+2a

where a = Propagation time/Transmission time

Calculate Transmission time:

Transmission time (T​​​​​​t) = 4096 / 65536

Transmission time (T​​​​​​t)= 625 m.sec

Calculate Window size:

Window size = 1+2(270/625)

Window size = 1+2(0.432)

Window size = 1+0.864

Window size = 1.864

Window size = 2

What are the disadvantages of a server-based network? -lack of centralized network security - need for a network administrator -
tigry1 [53]

Answer:

The server-based network has some disadvantages such as hardware-accelerated which is affordable. Effective operating system with a network. Requires a dedicated system administrator.

Explanation:

  • When one of the databases drops south all the people are being affected and the whole network can even be downgraded.
  • Costlier to set up and maintain.
  • Expensive: - The expensive server hardware equipment, database software platforms, and network installation can require significant source host and system administrator.
  • Administrating:-  Appears to require continual servicing by the system administrator and admin must behave with the relevant skills to preserve also that network infrastructure tracking is an important requirement.
  • Server Failure: - The complete functionality of the system is hosting events. If the server crashes, the whole system will go away even though all the customers rely solely on the computer.
  • Heavy Traffic:- The server is the infrastructure for managing entire elements of the organization that offer the server overload. Internet traffic will be even more relevant as the customer must start their contact session from boot time to disconnect. System routing must be properly maintained otherwise it tends to lead this same computer as a crowded state or the standard processes will be affected.

Pick the correct statements on the 64-bit machine representation of numbers.
Cerrena [4.2K]

Answer:Floating-point arithmetic is considered an esoteric subject by many people. This is rather surprising because floating-point is ubiquitous in computer systems. Almost every language has a floating-point datatype; computers from PCs to supercomputers have floating-point accelerators; most compilers will be called upon to compile floating-point algorithms from time to time; and virtually every operating system must respond to floating-point exceptions such as overflow. This paper presents a tutorial on those aspects of floating-point that have a direct impact on designers of computer systems. It begins with background on floating-point representation and rounding error, continues with a discussion of the IEEE floating-point standard, and concludes with numerous examples of how computer builders can better support floating-point.
