A computer virus is a program that replicates itself by attaching or copying itself into other programs stored on a computer, so it can spread when those programs are run. The defining idea is this self-replication through infection of existing software, which allows the virus to propagate across files, programs, or systems as users work with their computer. Viruses often execute only when the infected host program runs, and they may cause harm by altering data, displaying unwanted messages, or consuming resources. Backing up files is a legitimate safety tool, not a virus. A routine for cleaning malware is a remediation or removal tool, not a virus. A password management tool stores and autofills passwords, which is unrelated to the self-replicating, spreading nature of a virus.

This item is about your tendency to finish tasks before their deadlines, which taps into your time-management habits. Choosing the strongest form of agreement—“Very much like me”—best communicates that finishing early is a consistent pattern for you. It signals you routinely plan ahead, pace yourself, and leave time to review work, which is especially valuable in online settings where deadlines are strict and last-minute rushes can derail performance. The other responses convey weaker or hedged levels of agreement. Saying the statement is “very much like me” is still positive, but the shorter, direct form communicates the clearest, most consistent alignment with finishing early. Options that indicate little or no alignment would suggest you rarely finish early, which doesn’t match the idea of a strong tendency toward completing tasks before deadlines.

Connecting to the Internet means joining a network that has Internet access. The Internet is made up of many interconnected networks, so your device must connect to one of these networks to reach online resources. Once you’re on a network, you can access websites, apps, and services across the Internet. The other terms describe parts of the setup—like a modem that links you to your service provider’s network, or Wi‑Fi as a wireless way to reach a local network, or a cable as a type of physical connection—but the essential concept is the act of connecting to a network that provides Internet access.

You’re matching each task to the kind of software that handles it most efficiently. For writing a letter, a word processor is best because it gives you proper formatting, margins, fonts, and easy printing or sending with a professional appearance. For tracking donor names, a database shines because it stores records in structured fields (like name, contact info, donation history), makes it easy to update records, and lets you search or sort through many entries quickly. For budgeting, a spreadsheet is the right choice since it handles numbers, formulas, sums, and charts, helping you compute totals and create clear, updatable budgets. Trying to mix these roles would make one task harder: writing a letter in a spreadsheet would strip away formatting options, and budgeting in a database would complicate calculations. Using a database for letters or a spreadsheet for donor records would also be less efficient. So using a word processor for the letter, a database for donor names, and a spreadsheet for budgeting aligns each tool with its strengths.
