Which transmission method is being used?, Simplex, Parallel, Asymmetric, Serial, Why is serial transmission usually more reliable over long distances?, It sends no data packets, It does not need a receiver, It reduces the risk of bits arriving at different times, It uses several wires, A digital sign only receives information from a control computer. Which direction of transmission is used?, Half-duplex, Simplex, Full-duplex, Parallel, Two people use walkie-talkies, but only one person can speak at a time. Which transmission mode is this?, Half-duplex, Serial, Simplex, Full-duplex, During a phone call, both people can speak and listen at the same time. This is:, Half-duplex, Simplex, Parallel transmission, Full-duplex, Which statement correctly describes USB communication?, It cannot transfer data, It uses serial transmission, It uses parallel transmission only, It is a type of cloud storage, Data arrives with one bit changed because of interference. What has happened?, The data has been corrupted, The data has been printed, The data has been stored, The data has been compressed, An extra bit is added to make the total number of 1s odd. Which method is being used?, Encryption, Packet switching, Parity check, Echo check, A sender calculates a value from a block of data. The receiver calculates it again and compares the results. This is:, An embedded system, A MAC address, A packet header, A checksum, A receiver sends a copy of the received data back to the sender. Why?, To compare it with the original data, To increase storage, To change the encryption key, To assign an IP address, A message is automatically sent again because confirmation was not received. Which process caused this?, CPU, ADC, ARQ, DHCP, What does a positive acknowledgement indicate?, The router has failed, The file has been deleted, The computer needs more RAM, The data was received correctly, A bank changes readable customer information into unreadable characters before transmission. What has the bank used?, Virtual memory, Encryption, Packet switching, Parallel transmission, Which term describes a readable message before it is encrypted?, Ciphertext, Plaintext, Trailer, Checksum, Which term describes information after encryption has been applied?, Source code, Plaintext, Payload, Ciphertext, A company uses one secret key to lock and unlock a file. Which encryption type is this?, Symmetric, Asymmetric, Simplex, Parallel, A secure website uses one public key and one private key. Which system is being used?, Packet switching, Symmetric encryption, Asymmetric encryption, Parity checking, Which key in asymmetric encryption should remain secret?, Private key, Network key, Public key, Parity key, Which computer component follows instructions and processes data?, Keyboard, Monitor, CPU, NIC, A traffic light contains a small computer that performs one specific task. This is an example of:, Virtual memory, An embedded system, Cloud storage, A network server, During which stage does the CPU obtain the next instruction from memory?, Decode, Store, Execute, Fetch, During which stage does the Control Unit interpret an instruction?, Transmit, Fetch, Decode, Execute, During which stage is a calculation or instruction carried out?, Receive, Decode, Fetch, Execute, Which component performs arithmetic and logical comparisons?, ALU, NIC, ROM, Router, Which register contains the address of the next instruction?, MDR, Program Counter, CIR, Accumulator, A bus carries the location of data in memory. Which bus is this?, Control bus, Data bus, Address bus, USB, Which bus carries commands such as read and write signals?, Control bus, Data bus, Serial bus only, Address bus, A student opens several applications. Which memory temporarily stores the programs currently being used?, HDD, RAM, ROM, DVD, What happens to the contents of RAM when the computer loses power?, They move to ROM automatically, They are printed, They are permanently saved, They are normally lost, Which memory stores important instructions needed when a computer starts?, Virtual memory, ROM, Cache only, RAM, Which option is an example of secondary storage?, CPU register, Control Unit, SSD, RAM, A laptop connects to the school network using a hardware component. Which component is required?, ALU, Accumulator, ADC, NIC, A school computer receives an address automatically when it connects to the network. Which service assigns this address?, DHCP, CPU, ARQ, USB
