The basic internal components found in a computer tower also called as computer case are the following:
1. The motherboard
2. The power supply
3. Hard drives
4. Fan
5. Random Access Memory - RAM
6. CD - Rom's and DVD - Rom's
7. Ports and Hubs
These are found inside your PC case.
Answer:
2^11
Explanation:
Physical Memory Size = 32 KB = 32 x 2^10 B
Virtual Address space = 216 B
Page size is always equal to frame size.
Page size = 16 B. Therefore, Frame size = 16 B
If there is a restriction, the number of bits is calculated like this:
number of page entries = 2^[log2(physical memory size) - log2(n bit machine)]
where
physical memory size = 32KB which is the restriction
n bit machine = frame size = 16
Hence, we have page entries = 2^[log2(32*2^10) - log2(16)] = 2ˆ[15 - 4 ] = 2ˆ11
As we change password when
1. we forgot the previous password.
2. when the previous password is leaked due to some reasons.
In case 1 we can change the password to the same as well with no change the problem will be solved but for case 2 at least one or for more safety all characters should be changed.
Answer:
There are different kinds of operating systems: such as Windows, Linux and Mac OS
There are also different versions of these operating systems, e.g. Windows 7, 8 and 10
Operating systems can be used with different user interfaces (UI): text user interfaces (TUI) and graphical user interfaces (GUI) as examples
Graphical user interfaces have many similarities in different operating systems: such as the start menu, desktop etc.
When you can recognize the typical parts of each operating system’s user interface, you will mostly be able to use both Windows and Linux as well as e.g. Mac OS.
THE ROLE OF OPERATING SYSTEM IN THE COMPUTER
An operating system (OS) is a set of programs which ensures the interoperability of the hardware and software in your computer. The operating system enables, among other things,
the identification and activation of devices connected to the computer,
the installation and use of programs, and
the handling of files.
Answer:
Syntax is essentially the punctuation and grammar rules for a computer language.
Explanation:
Certain characters and words have special meanings and must appear in a particular order for the computer code to make any sense. A simple example from line 3 in Figure 2.2 is the piece of HTML code <head>.
