Challenge your competence level in computers, computing, algorithms, hardware and software with these Computer science questions and answers.
The two types of operating system are
command line and graphical user interface
translators and assemblers
system software and application software
UNIX and LINUX
Correct answer is A
Operating systems can be categorized into two types based on their user interface: Command Line Interface (CLI) and Graphical User Interface (GUI). CLI requires users to type commands to interact with the system, while GUI uses visual elements like icons, windows, and buttons for interaction

external modems are PCI or ISA expansion cards while internal modems are traditionally plug into a serial port on the computer
internal modems are PCI or ISA expansion cards while external modems are traditionally plug into a serial port on the computer
external modems are PCI or ISA expansion cards while internal modems are USB modems
they are PCI or ISA expansion cards
Correct answer is B
Internal modems are PCI or ISA expansion cards, they tend to be simple to install while external modems are traditionally plug into a serial port on the computer

cold booting
hard reboot
cold reboot

EDVAC was produced using which of these concepts ?
packet routing
stored program
circuit switching
packet switching
Correct answer is B
EDVAC (Electronic Discrete Variable Automatic Computer) was produced using the 'stored program' concept. This concept is a design architecture for computers where the instructions to be executed by the computer are stored in the same memory that holds the data. 'Circuit switching', 'packet routing', and 'packet switching' are concepts related to network communication, not computer design
